Foreign Treasury Holdings and Pettis

In the last reported month Foreign Treasury holdings have gone from 5652.9 to 5653.5 or up only 0.6 billion. Over the last 8 reported months it has gone from 5691.1 to 5653.5 or down 37.6 billion.

If you look at the last 5 reported months China has gone from 1297.3 to 1304.5 but last month it was 1293.8.   So last month you could say they were slightly down for 4 months and this is slightly up for 5 months.   But China has since said it is No Longer in China’s Interest to Increase Reserves.

Michael Pettis says that  If foreigners buy fewer USD assets, the US trade deficit must decline.  From this Pettis says that "China Won’t Sell Our Bonds Anytime Soon".   Since they have stopped buying bonds, and the US still has a $40 billion per month trade deficit, I think Pettis overlooked something.   Seems to me that foreigners can buy up other assets besides bonds.   They could be buying land and stocks for example.

I would certainly rather buy US land or US companies or gold than US bonds, given the rate of money creation.    It would seem I am not the only one.   This is a list of famous US brands now owned by foreigners
  1. Budweiser, now owned by Anheuser-Busch InBev N.V., which is based in Leuven, Belgium
  2. Alka-Seltzer, now owned by German company Bayer Schering Pharma AG
  3. Ben & Jerrys, now owned by British-Dutch Unilever
  4. AMC theaters, now owned by the Chinese
  5. 7-Eleven, now owned by the Japanese company, Seven & I Holdings
  6. Woman’s Day Magazine, now owned by the French company, Hachette Filipacchi M├ędias, S.A
  7. Purina, now owned by the Swiss company, Nestle
  8. Gerber, now owned by the Swiss pharmaceutical giant, Novartis
  9. Firestone, now owned by the Japanese Bridgestone Corporation
  10. Citgo, now owned by the government of Venezuela
  11. French’s Mustard, now owned by Reckitt Benckiser, a British conglomerate
  12. Frigidaire, now owned by Sweden’s AB Electrolux
  13. The Plaza Hotel in New York City, now owned by Israeli billionaire Yitzhak Tshuva’s El-Ad Group
  14. Trader Joes, now owned by German billionaires Karl and Theo Albrecht
  15. Dial soap, now owned by Henkel KGaA, based in Dusseldorf, Germany
  16. Sunglass Hut, now owned by Italian eyewear seller Luxottica Group

Past Hyperinflation in France vs Current Hyperinflation in Venezuela

It is interesting to look at articles about past hyperinflation in France and how similar these are to current articles about hyperinflation in Venezuela

In both cases the government deficit was being financed with new money and that was the true cause of the hyperinflation.   In both cases the government blamed shop keepers for rising prices.  In both cases shops were basically robbed with government approval.   In both cases shops had to shut down as they could not operate at the prices they were allowed to charge.

Even in the days of the Internet, the average person just does not understand hyperinflation.

List of 590+ Dead Currencies

This list of 590+ dead currencies is interesting.   I think there are nearly 150 listed as "hyperinflation".   I expect that many of the others listed as "war" would count as hyperinflation if we used a 26% yearly rate as the cutoff.   When a war is going poorly the currency usually is going poorly as well.  So while it is reasonable to list war as the reason the currency died, the currency probably hit the 26% inflation mark before it died.

Note that ounces of pure silver or ounces of pure gold will never completely fail to have value.

How the US Dollar Will Fail?

Bernanke made new money but kept most of it in the Fed by paying interest on excess bank reserves.   If you imagine a big black box around both the Federal Government and the Federal Reserve, then to everyone outside this box there is no difference between interest on government debt and interest on excess reserves.   So really excess reserves are like government debt as far as the impact on the economy, inflation, and risk of hyperinflation.

It looks like a Yellen led Fed wants to reduce the interest rate paid on excess reserves.   Interest rates have been rising, so to provide enough incentive for banks to leave money as excess reserves the Fed would have to raise the interest they pay.  Instead they are talking of lowering the interest rate they pay.

Looks to me like a good bet for how things fail is that the Fed does not keep rates on excess reserves competitive, so that money comes flooding out into the real economy. 

Of course, the Japanese Yen failing and then the UK and US following is another good bet.

Armstrong and Hanke out of touch with real world definitions

If the US had 100% inflation in 3 years just about everyone except Armstrong and Hanke would say, "the US has hyperinflation".  Here is a good post on this idea, Prof. Steve Hanke, Your definition of hyperinflation is just nonsense.

Armstrong gets hyperinflation wrong

In Armstrong's latest post he says:

Hyperinflation - All Just Hype
Hyperinflation is a good sales pitch but it PRESUMES government will honor all its promises. There is no indication in history that any established government has EVER done such a thing. They will confiscate everything they can, raise taxes that kill the economy, and the less revenue they generate the higher interest rates will rise forcing further defaults on debts.

Hyperinflation PRESUMES they will honor their debt. If they do not, it just vaporizes and that is DEFLATIONARY.
If we use 26% inflation per year as the cutoff for hyperinflation, then hyperinflation has happened many many times.  In the US alone there are several in the colonial period, the revolutionary war, and the civil war.  Armstrong makes it sound like hyperinflation is something that can only happen in a bad theory with false assumptions.  Really it is something with many historical examples.  Plenty of real world experimental evidence.

Really, there is no history of a government ever defaulting on debt in their own currency.  They just print to pay off the bonds.   If you look at Japan now the interest is only 0.19% on 5 year bonds, not rising higher.  This is because the central bank of Japan is making money like crazy to buy up bonds.  This is the normal sort of thing leading up to hyperinflation.  In the end the value of the paper they are using to pay off debts is a small fraction of the original value, so this is not particularly honorable, but they do not default.  

Armstrong has hyperinflation all wrong.

Hyperinflation is a market revolt not a political choice

Again and again I see people saying that hyperinflation is a "political event" or a "political choice".    There are political events and bad choices leading up to hyperinflation but really hyperinflation is a market revolt against government debt and and deficit spending.   Hyperinflation is a market response to bad politics, not the bad politics themselves.   Never do politicians explicitly choose hyperinflation, they just keep trying to kick the can down the road further with deficit spending and then the market revolts.

How could they not expect inflation?

Some day in the future people will look back on our time and graphs like this and wonder in amazement, "How could they not expect inflation?".

Real life success in hyperinflation detection?

I am wondering if any readers have lived through hyperinflation and what was their first clue that hyperinflation was coming?    Or if people have read any real life examples someplace on the net if they can say how people first became aware hyperinflation was coming (links if you have them).    Like did foreign exchange rates change first?   Did food go up first?  

One place I read that stock markets in Germany, Zimbabwe, and Venezuala went up early on.   I note that Japan's stock market is well up.   It seems that when people get worried about money one of the first things they do is buy stocks.  So this seems a good clue.

Another early way is when the government robs the central bank of its foreign reserves.   Using the "backing view" in my many explanations of hyperinflation we can tell this will cause hyperinflation.

People rushing to get out of bonds while the central bank is buying also seems a good warning.

It would be nice if there were people who had already had success in detecting hyperinflation ahead of time and we could find how they did it.   I don't mean predicting that sometime there will be hyperinflation but I mean in telling when something has already started but before the prices are going up fast.

Thanks for any help anyone can provide.

Food Prices as Early Warning for Hyperinflaton

It seems that in previous hyperinflations food and energy prices went up first.

Food and energy cross boarders and so foreign exchange rates impact them quickly.   It seems that a currency heading for hyperinflation does poorly in foreign exchange markets.

When times get tough there are people selling off optional things but everyone keeps buying food.  Even land and houses become optional as people can move in with parents or rent.   So prices of some things can go down while food is going up, making it look like the overall price change is not too much.   But as a leading indicator for hyperinflation, I think we should only look at food and energy.

Every household buys food most every week.   So they see the prices going up on food.   It does not matter so much what government says the CPI is to people who notice that a grocery cart full of food costs more than it used to.  Their personal perception of the rate of inflation is shaped by what they see in food prices.

We are currently seeing food inflation in India and in Japan.

The world food price index is one way of looking at how the US dollar is doing.

If your bank account pays 1% and the price of a can of tuna is going up at 10% then you are better off investing in canned tuna than putting your money in the bank.  It would be very rational to take any extra money at the end of the month and buy canned food.   After enough time that most people understand what is going on, I think we will eventually see rational behavior.

If food is going to be up over 30% in 3 years it is just not reasonable to invest in government bonds paying 0.19% per year for 5 years, or less than 1% total after 5 years.   Better to buy canned food.

As more and more people get out of bonds and buy real things, the central bank will make more and more new money to buy up the bonds that nobody else wants.  If nobody at all were buying bonds, the government could not deficit spend, which at this point is not optional.  So the central bank must buy bonds.  The price of food will go up even faster, and it will make even less sense to hold government bonds. 

I think we should keep an eye on food prices in any country at risk for hyperinflation.

BOJ only buyer of JGBs

The Bank of Japan is now the only buyer of Japanese Government Bonds.   This is what happens in the early stages of hyperinflation.   Next I would expect JGB selling to go faster and faster.  The death spiral could start anytime now.

Hunt Brothers vs. Japan

In the 1970s the Hunt Brothers were able to drive the price of silver up to about $50/oz.  With around $1 billion they controlled over half the world's silver.   There is many times the amount of money in circulation today as back then.   The stockpile of above ground silver is smaller than back then.   Imagine if Japan gets hyperinflation, so the Yen is not a good store of value, and many people in Japan start buying silver as a store of value.   The price of  silver could go way up.

Foreign Treasury Holdings Down

The monthly report on foreign Treasury holdings shows that they declined again this past month.   Over 4 months they are down from 5721.8 to 5590.1 for a total loss of $131.7 billion. This is an average of about $33 billion per month.

In the prior 8 months foreign holdings went from 5381.6 to 5721.8 for a total increase of $340.2 billion or $42.5 billion per month.

It is too early to say for sure, but there is a chance that foreign holdings have peaked and might keep going down from here.   Going from an average increase of $42.5 billion per month to an average decrease of $33 billion per month is a $75.5 billion per month change. 

This is on the order of the Fed's $85 billion per month monetization.    In fact, you could imagine that most of the Fed's buying over the last 4 months is just compensating for this change.   If the Fed had stopped buying, and foreigners kept buying instead of selling, the supply/demand situation would be similar to what it is now.   So if this change by foreigners is ongoing, it is a  big change.

There is a good article on this topic.

The Fed is now buying more bonds faster than the Treasury  is making new bonds, so someone had to be getting out of bonds.   It seems it is foreigners.

It could increase into a panic at some point.  It is worth watching these numbers each month.  It seems to indicate less foreign confidence in the dollar and less desire to use it as the global currency.  The Triffin Dilema has long predicted the end to an unbacked reserve currency.  We may be seeing the start of this.

Polling Questions

I believe that with some practice a set of polling questions could be developed that could provide an early warning for hyperinflation.  Below are some possible questions:

1)  Imagine a 90 year old friend/relative has $5,000 and the current cost for casket and funeral services is $5,000.   Would you recommend that this person pay the funeral home in advance or put the money in a saving account to be used after their death?

2) Do you think it is better to hold onto your gold jewelry or to sell it now and put the cash in the bank?

3) How important to you is it to have your salary indexed for inflation?

4) Do you feel the prices on necessities are going up faster than other prices?

5) Would you advise a friend/relative to buy long term bonds in a retirement account that only permits changes once a year?

6) If you personally own any bonds do you plan to roll them over?  Y/N/na

7) Do you expect interest rates to go higher?

8) Do you expect inflation rates to go higher?

9) Do you plan to buy any gold or silver coins?

10) If you had the option of having your salary specified in the local currency or a foreign currency of your choice, which would you choose?

11) Do you know of people moving their wealth out of the country?

12) Do you feel the government budget deficit is out of control?

13) If you had extra money at the end of the month do you think it is better to buy extra things you will use in the future or just save the money?

14) Do you have confidence in your countries bonds?

15) Do you have confidence in your countries currency?

16) Do you have confidence in your countries central bank?

17) Do you have confidence in your countries government?

18) Do you think the central bank needs to create more money?

19) Do you think the current level of government deficit spending is sustainable?

20) Do you think inflation will get bad enough to hurt economic growth?

21) Do you think your currency will be a safe store of value over the next decade?

22) Do you think some more inflation would reduce the government debt burden?

23) Do you think politicians have too much/little influence over the central bank?

24) Do you think it is ok if they print new money to pay off bond holders?

25) Do you think the central bank is funding the government deficit spending?

26) Does your government have too much foreign debt?

27) Does your government have to pay for too many imports?

28) Are bond prices high?

29) Do government employees get inflation raises faster than others?

30) Do you feel that the government has protecting the value of the currency as a higher priority or creating jobs as a higher priority?

31) Are you afraid prices will go up faster and faster?

32) Is the government paying out money to too many different special interests?

33) Have you seen or do you expect price controls?

34) Do rising prices cause the government to print more money?

35) Do you think the same currency will be around 50 years from now?

36) Has the central bank been buying bonds for a long time?

37) Does the government need to borrow money to pay the interest on the debt?

38) Do you think the central bank will reduce the rate it is making new money in the next year?

39) Do you think that central bank interest rates are a good deal for big time borrowers given the current inflation rate?

40) Do you keep a bigger stock of canned food than you used to?

41) Do you think it is easy or hard to get a job now?

42) Is your government stable?

43) Do you think there is a danger of an economic crash?

44) Have you noticed any new gold dealers in the last few years?

The idea is to poll a bunch of different countries that seem to be at risk for hyperinflation each month.   After awhile if some do get hyperinflation, then you could look at the data and see if there were some questions that seem to be good predictors.  Then you keep refining and repeating this and you get better and better at predicting hyperinflation. 

This is a post that I expect to update from time to time.

What are the numbers for Japan?

This post is to collect together some information on Japan and to point out a confusion that I and I think some others have from the Japanese numbers.

Video's on Japan situation

OtterWood video on Japan.

Kyle Bass video on Japan.

My posts on Japan

Japan will soon be zooming past their inflation target of 2%.

Japan is already printing money at hyperinflationary rates.

Japan to be First Currency Domino.


I was commenting on Sumner's blog and he pointed out that my numbers for Japan did not look right.   The Japanese ministry of finance web site made it seem like national debt service was already about 25% of expenditures and  50% of taxes, even at near zero interest rates.  However, Krugman says this 25% includes principle for bonds coming due

It is not clear from the MOF web site how much is spent on interest.  Kyle Bass, and someone trying to rebut him, say that interest is about 25% of taxes.  This would mean half of the reported "national debt service" is interest and half principle.

Sumner also says that for hyperinflation it is only the net debt to the public that matters.  He says for Japan this is about 100% of GNP.   It does make sense that net debt is the correct number to use.  This also explains why Japan could get debt over 200% of GNP without hyperinflation

An article in the economist has Japan's net debt at 114% of GNP in 2010.   This article has net debt, years to maturity, and primary budget balance.  These all are important factors when looking at the chance of hyperinflation.

USA Hyperinflation Risk

If the US were to head into hyperinflation we know where the extra money would come from.  It would come from excess reserves, monetization of debt held by the public, and monetization of the new deficit.    Imagine that we are going to have hyperinflation over the next 12 months so we count both the current debt and the deficit coming over the next 12 months.   We can combine these 3 things in a graph and see how the potential pool for hyperinflation money is changing over time.  Below is a FRED Graph with these 3 things combined.  The only reason it looks like it is flattening out at the end of the curve is that the deficit data does not go as far as the other data.

Also during hyperinflation the velocity of money goes up and this adds to inflationary pressure.  The lower the velocity of money is to start with the easier it is for it to start going up.  We are currently at record low velocities.

The potential for hyperinflation is going up fast.  In practice as prices start to go up the actual deficit will as well but this makes a nice way of estimating what resources will be available to trigger hyperinflation.

Good Paper on Four Hyperinflations

The paper, The Ends of Four Big Inflations, explains what happened in 4 hyperinflations after WWI.   In each case the government was spending far beyond their taxes.  In each case the inflation ended when they got their deficit under control.    I believe this is true for all hyperinflations and can not find any counterexamples.

This was recommended to me by Tom Brown and Michael Salemi.  Thanks to you both!    I now recommend this paper to you.

I found another interesting paper, Determinants of Hyperinflation: Case Studies from Latin America.

This article on Weimar Germany is good.

Hyperinflation Explained in Many Different Ways

Hyperinflation is part of the experimental data that any good economic theory should be able to explain.   There are many different economic schools of thought and they often have very different views of hyperinflation.  I am trying to collect as many different explanations here as I can.  I think it is fun to be able to understand this problem from many different angles.  If you know of any other explanations, then please post them in the comments.  A good explanation should fit with some common characteristics:  there are always high government debt and deficit levels, hyperinflation can start very suddenly, it often accelerates,  it can go on for years, it is very hard to stop, but sometimes it is stopped by balancing the government budget.

The biggest flaw in most people's understanding of hyperinflation is that they think if we have low inflation now we are safe for a long time.  As you read through each explanation, try to imagine how fast things could switch from low inflation to hyperinflation.

Equation of Exchange with Positive Feedback Loop

 There can be a feedback loop where the more the central bank makes money and buys bonds the less people want to hold bonds, but the less people hold bonds the more the central bank has to monetize so the government has cash to operate.  This results in a flood of new money and inflation.  The inflation causes the velocity of money to go up.  Governments almost always try to fight inflation with price controls.  The resulting shortages reduce the real GNP.   Using the equation of exchange view of hyperinflation we can see that if the money supply is going up fast, the velocity of money is going up fast, and GNP is going down that prices will go up very fast.  But nobody wants to hold bonds in a currency that is dropping fast, so this can spiral out of controlHyperinflation can be simulated using this view.

Corrected Modern Monetary Theory

A simple model makes it easy to understand hyperinflation.  In this model all government spending uses newly made money and we imagine money collected from taxes and bond sales is just destroyed.   In this model bonds are paid off with newly made money.    If much of the government debt is short term, and people stop rolling over bonds, then the government would end up paying off lots of bonds with lots of new money.   If there is a full bond panic, then this could result in hyperinflation.

Unsustainable Interest Expense

If the deficit is large then the debt and the interest on the debt can both be  growing faster than the tax base.  In this case then, at some point, the  interest on the debt adds so much to the debt that it is clear there is no hope of really paying this off.  Often about when this is becoming clear the interest rates go up and the interest expense shoots up so that it is obvious to all this can not go on.   The alternative is for the central bank to peg interest rates by buying bonds very fast.  Either way, it gets to where all the government can really do is print money to pay off the debt.   This then makes lots of new money and the value of each unit goes way down.

Inflation Tax View

Inflation is a tax on those who hold money.   The higher taxes are the more people change their behavior to avoid the taxes.  As the inflation tax gets higher and higher people change what they do so that the real value of the money they hold goes down.   This involves spending money faster and keeping lower real balances.  This can make the total real value of the currency outstanding go down even as the nominal value is shooting up. But the lower the real value of currency out there to collect an inflation tax from, the more drastic the same real value of inflation tax impacts price levels.   In other words, the more people try to avoid the inflation tax the more extreme the government has to get about printing money to get the same real amount.  But the more extreme the inflation tax the more people try to avoid it.  This can spiral out of control, often to where people avoid that currency altogether.   Search for Krugman here for more.

Backing View or Real Bills Doctrine

In the Real Bills Doctrine a bank can issue as many notes as it wants without causing inflation as long as it gets assets of real value that could be sold to withdraw the notes.   If it is getting bonds they should be for less than 60 days and come with collateral.   In hyperinflation the central bank buys government bonds.  The problem here is that the only collateral is a  real tax base.  So the more bonds they buy the less real collateral they have per bond.  Also, they typically buy long term bonds which go down in value as interest rates go up.   So the current value of the assets backing the notes per note issued goes down.  The value of notes is determined by the value of the assets per note, so the value of the notes goes down if the value of the assets goes down.   This can spiral out of control.  As the notes go down, the value of the bonds goes down, but as the value of the bonds goes down, the value of the notes goes down.  As you get hyperinflation the government gets weaker and the amount of real taxes collected goes down.  This further reduces the value of the backing/bonds at the central bank.    This feedback loop can go on and destroy the currency.

A central bank backing its currency with long term bonds is like backing the currency with the future value of the currency.   Holding a 30 year bond as backing is like backing the currency with the value of the currency 30 years from now.  There is a dangerous recursion here.   Once the future value starts going down, the backing goes down, which reduces the current value of the currency, which reduces the future value, and things spiral out of control.

Supply and Demand

If a currency is losing value fast the demand for that currency goes down.  This makes the value of the currency go down even more.   If the government needs to print money to cover a deficit of a certain real total value, to cover real expenses in the real world (employees, retired people, unemployed),  then as the value of the currency goes down it is forced to increase the supply faster and faster.   This can spiral out of control with supply going up fast while demand goes down fast and the currency gets destroyed. 

Rational Expectations

Rational expectations theory holds that economic actors look rationally into the future when trying to maximize their well-being.  History shows that when the government starts using new money to fund a big deficit that the currency will go down.  Once economic actors expect the currency to go down, they work to avoid that currency.  The faster it is going down the harder they work to avoid it.   The more people try to avoid the currency the more it goes down.  You can get  a feedback loop or panic.  Eventually everyone is out of that currency.

Half Dead Money

Good money is both a store of value and a medium of exchange.   During hyperinflation the currency is no longer a good store of value.   It can be viewed as half dead money.  Such money often keeps losing value till it eventually becomes completely dead.

Replaced as Store of Value

The higher the inflation the more the store of value function of the currency is replaced by other things.   In the past if someone did not need their money for 6 months, then the money might stand still for 6 months.   But the higher the inflation rate the less sensible it is to use the currency as a store of value.   So people who don't need their money for some time use something else as a store of value.  This might be another currency, purchasing goods in advance of when they are needed, buying gold or silver, or not selling something till they need the cash.   The less the currency is used as a store of value, the higher the velocity of money, and the higher the inflation.   But the higher the inflation, the less it is used as a store of value.   This makes a death spiral that is hard to escape from.

Loss of Confidence or Faith

For some reason the public becomes less confident in the currency.  This may be from too much new money, from central bank monetizing government debt, from war, from corrupt government, or whatever.   As the public loses confidence they don't want to hold the currency as long and the velocity of money goes up.  However, as the velocity goes up the prices go up, which makes confidence even lower.  This can spiral out of control.

"If there is a real loss of confidence in the dollar, then I think we are in trouble. That is something that has to be watched."  - Paul Volker

Inflate Away the Debt

The idea here is that those in charge have decided to inflate away the national debt by printing money and this causes hyperinflation.   If politicians have ever made such a decision I can not find them admitting it publicly.   To me hyperinflation happens when there is no good way out of a bad situation.   I doubt there was ever a "vote for hyperinflation".  Perhaps they voted to monetize the debt but did not understand it would cause hyperinflation.  I can not even find that though.

When Politicians Get Control of Printing Press

Politicians can spend unlimited amounts once they  are able to get as much money as they want from the printing presses.  Usually this is done by getting control of the central bank and making them buy as many government bonds as needed.   Once this is how things work, all restraints on the amount of money are gone.  The more they print, the higher the prices.  The higher the prices, the more they print.  They print and spend into oblivion. 

Khan Academy

The Khan Academy video explains hyperinflation as two feedback loops.  First, the more the government prints, the higher the prices go, but the higher the prices go, the more the government needs to print to pay for whatever it needs to pay for.   The other cycle is that the faster prices go up the more people hoard real goods.  But the more people hoard real goods and less cash, the bigger the impact of constant real value of new money (and so bigger nominal value).  Hoarding can be done by buying extra stuff ahead of when they normally would or waiting to sell things until prices have gone up.  They keep less cash and more real goods.   These two cycles can spiral out of control.

Addiction to Monetary Heroin 

The economy and government get addicted to cheap money.  The longer our reliance on it and the greater our dependence, the more it takes on the toxic dynamics of an addictive drug: we can only sustain a feeling of wellbeing by increasing resort to it.   If at any point the cheap money is removed the economy and government will nearly fall apart.  But over time a larger and larger dosage is needed.   Eventually the patient dies.

Taxes for Bond Holders

Bond holders that are paid with money collected from taxes can expect to get the value of their initial investment back plus interest.  However, when governments start printing money to pay bond holders the value of the money will be going down and holding bonds for years is a bad deal.  Bond holders know this and can head for the exits when governments start doing this.  The faster bond holders exit the faster the government will print.   So this can spiral out of control in a bond panic.

Market Perception

If the market thinks that the central bank is funding the government deficit with new money, then you will get hyperinflation.   There can be deficit spending, and even monetization, as long as the market thinks the deficits will be controlled eventually.  It must expect that in the future the monetization will unwind, stop, or at least slow down.   Once the market thinks the deficit will not be controlled, and the monetization will continue without bound, then hyperinflation comes.  It is like things go too far and something snaps.  Initially the market is willing to buy government bonds but after this tipping point they are not.  The central bank becomes the only bond buyer and is funding the deficit with no way to get back to the previous state.

Government with Real Foreign Obligations

If a government with a large deficit needs to pay another country some real amount (say gold bars for war reparations, oil being imported for military, government debt denominated in a foreign currency, imported food for local population), then as it attempts to do so by printing local currency, it causes inflation.   The more inflation the more it needs to print to pay the same real amount to the foreign country.   This can spiral out of control.

Bond Market Bubble

The central bank buys up more and more bonds driving the price of bonds up and interest rates down.  At some point this bubble pops.  As it pops, people stop rolling over bonds and the central bank is forced to monetize everything so the government still has cash to stay in operation.  This makes for a flood of new money and causes hyperinflation.

Wage Price Spiral

Government wages, unemployment benefits, social security benefits, medical benefits, retirement benefits, etc. are indexed to inflation.  This means that the government expenses go up right away with inflation.   As government pays out more money in wages and other things, that new money can add to the inflationary pressure, making prices go up more.  If the government is deficit spending and the central bank is monetizing debt, this can spiral out of control.

This does not work for private wages.  There is no way that private wages going up can ever spiral out of control making wheelbarrows full of money.  The spiral needs to include government to get the new money and keep going.

Diminishing Real Stock of Money

With inflation you can have a diminishing real stock of money.  It can get to where economists and business people are advising the central bank that the economy does not have enough money.   So the central bank makes more money.  After this the velocity of money goes up and inflation goes up more, making the real stock of money even lower.   This cycle repeats until the real stock of money is virtually zero, as nobody wants the money. 

State Theory of Money

In the State Theory of Money, fiat currency is a creation of the state.  The state has a monopoly on the creation of this fiat currency.  By making and spending money as well as taxing back some of this money it can regulate the quantity and the value of this money.  If for some reason the spending and creation of money get too out of balance with the  taxing, then the value can go down.  If they are way out of balance, then the value can go down fast.

The Quantity Theory of Money

The velocity of money can go from changing hands on the order of once a month to changing hands on the order of once a day.   This can account for a factor of 30 chance in price.  However, prices can go up by factors of even billions.   The vast majority of this price change is simply due to the quantity of money.    The more money you make the less it will be worth.  In hyperinflation the central bank makes lots of new money to fund the government deficit and the value goes down proporionally.

Cagan's Explanation

In Cagan's explanation of hyperinflation, the velocity of money goes up as people's expectation of inflation goes up.  Over the long term the higher the quantity of money the lower the value.   People's expectation of inflation is adjusted up if their previous expectation was exceeded.   In this model you can sometimes get control of inflation by stopping the money creation and sometimes things have passed a tipping point where even if you stop making new money the currency will keep crashing.

This model does not address why a government would not be able to stop making money but that is simple, if they are spending more than they get in taxes and nobody is buying their bonds.

Government No Longer Wins by Money Printing

For modest amounts of inflation when a government prints money (or borrows from a central bank that prints) it gets ahead.   It has the new money that was printed and downside of prices going up is shared over a wide base, not just the stuff it buys.  Often prices go up long after the new money is spent.  So initially the government is better off after the money printing.    Eventually some tipping point is passed and for each amount of money printing the prices on just the stuff government has to pay for go up more than what it got from the money printing.  So each time it prints it gets worse off and needs to print more.  However, if they are spending much more than they get in taxes and nobody is buying their bonds, they are trapped and all they can do is print (or borrow from the central bank which makes the money).   So there is a death spiral with uncontrolled money printing.

Keynesian Bubble Economics

Most government economists are Keynesians.   When a bubble pops Keynesians advocate money printing to mop up and make a new bubble.   To clean up the previous mess and make a new bubble takes more money printing than the previous bubble did.  So you get a sequence of larger and larger bubbles.  Eventually it is not possible to make a new larger bubble without making so much money that the currency collapses.

Theory of Reflexivity

Perceptions tend to create their own reality.   If people believe the money is going to become worthless, then it probably will.

Democracy Causes Hyperinflation

There have been studies that indicate democracies are more prone to hyperinflation than dictatorships.   Democracies are more prone to run large deficits because of trying to give too many things to too many different people.  Once the budget is out of control then inflation can get out of control.

Friedman said, “inflation is neither a capitalist nor a communist phenomenon.  In our modern world, inflation is a money printing phenomenon."

Lenin's View

There is no subtler, no surer way to overturn the existing basis of society to than to debauch the currency. The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner, which not one man in a million is able to diagnose. -As reported by Keynes

Keynes View

Keynes wrote about hyperinflation:

"In the latter stages of the war all the belligerent governments practiced, from necessity or incompetence, what a Bolshevist might have done from design. Even now, when the war is over, most of them continue out of weakness the same malpractices. But further, the governments of Europe, being many of them at this moment reckless in their methods as well as weak, seek to direct on to a class known as "profiteers" the popular indignation against the more obvious consequences of their vicious methods. [...]

"The inflationism of the currency systems of Europe has proceeded to extraordinary lengths. The various belligerent governments, unable or too timid or too short-sighted to secure from loans or taxes the resources they required, have printed notes for the balance. In Russia and Austria-Hungary this process has reached a point where for the purposes of foreign trade the
currency is practically valueless. [...]

"The preservation of a spurious value for the currency, by the force of law expressed in the regulation of prices, contains in itself, however, the seeds of final economic decay, and soon dries up the sources of ultimate supply. If a man is compelled to exchange the fruits of his labors for paper which, as experience soon teaches him, he cannot use to purchase what he requires at a price comparable to that which he has received for his own products, he will keep his produce for himself, dispose of it to his friends and neighbors as a favor, or relax his efforts in producing it.

When money permanently escapes central bank

The central bank is like a huge market player.  When it is buying bonds it drives up the prices and lowers the interest rates at the same time it is injecting liquidity.  If it later wants to withdraw that liquidity by selling the bonds then the prices of bonds will be lower and it will not be able to withdraw as much as it injected.  If it bought long term bonds and interest rates went up substantially, then the value of the bonds will be far less than what it paid earlier.   This means that even if it sold all the bonds it would not be possible to withdraw all the money it injected.   Note that with short term bonds it could just hold them till they were paid off and not lose money but if there is an inflation problem and it has to wait 30 years to withdraw the money then it has failed. If inflation goes up and bonds drop in value then it can't effectively fight inflation as the assets it has to withdraw cash are no longer valuable enough to do the job.   Normally a central bank should be able to withdraw all the money it has created at near the value it originally had.  However, a central bank holding lots of long term bonds where the value has crashed can no longer do this.   The money is out there but can not be withdrawn.  The central bank has lost control of it.

Flaw in "Government can't run out of money"

There are those who think a government can't run out of money because it has a printing press.     Hyperinflation exposes the error in this way of thinking.  If the government is increasing the money supply too fast, then their currency is not a good store of value and people won't want to hold it.   As people want to hold it less and less it makes it worse and worse as a store of value.  As prices go up the government needs more and more money, but since it thinks it can't run out of money it just prints more.   This can spiral out of control.   The government can print so much currency that it is no longer accepted as money.  At that point the government is out of money even though it has a printing press.

Unsustainable Currency Peg 

Sometimes a central bank is trying to both peg the local currency to a foreign currency and print money to help a government that is running a deficit.   By doing this it does not really have enough reserves to support the peg and can rapidly lose much of the reserves it does have attempting to maintain this unsustainable currency peg.   There are also times where the government just takes a central bank's reserves.   Eventually the central bank's reserves get  dangerously low and has to give up the peg.  At this point the currency can suddenly crash and they can get hyperinflation.

Hard Money View

Paper currencies all seem to fail eventually.

Like a Nuclear Reactor

The policymakers at the Fed think they are dialing a thermostat up and down, but they're actually playing with a nuclear reactor.  A runaway chain reaction can melt the whole thing down.    Paraphrase of Jim Rickards,  Currency Wars.

QE Trap / Roach Motel of Monetary Policy

Once the government/central-bank has artificially lowered interest rates to stimulate the economy, it is very hard to ever stop.   If they even hint that they might slow down a bit on the money creation then interest rates shoot up and hurt the recovery, so the central bank can not slow the money creation.   In fact, they will have to print faster to try control interest rates once they start going up.   But the more money they make the more inflationary pressure there is, which will push interest rates up.  So the central bank ends up fighting harder and harder to try to keep rates down by making money faster and faster.  This spirals out of control and you get hyperinflation.

Non-Linearity of One More Trillion

The government can keep adding trillions in debt one by one.  But at some point the market reacts very differently to one more trillion in debt than it did for all the previous times one more trillion in debt was added.   When we get this "non-linear reaction" we say the government has passed some "tipping point" and things start to "spiral out of control".   You can see this in all the previous cases of hyperinflation and yet people always seem surprised when it happens to them.   Since even people who understand the danger of hyperinflation don't know exactly when the tipping point will come, as they warn of the danger for years they will be viewed as being proven wrong for years, right up till when it hits.

Borrowing To Pay Interest

After things get so bad that the government has to borrow just to make the interest payments on the debt, then things have gone too far.  To service the current debt they must go further into debt.  Bond holders can tell where this is going and flee.   The central bank becomes the only bond buyer.  The more the government borrows, the higher the interest payments, and the more they have to borrow.   But as they do this the central bank is making new money.   This can spiral out of control making hyperinflation.  

Mises/Austrian Crack-up-boom

Money is, like any other good, subject to the irrefutably law of diminishing marginal utility. It is this law, which is implied by the axiom of human action, which is at the heart of Mises's praxeology.  If the central bank is expected to increase the money supply in the future, people can be expected to rein in their money demand in the present — that is, increasingly surrendering money against vendible items.

"Once public opinion is convinced that the increase in the quantity of money will continue and never come to an end, and that consequently the prices of all commodities and services will not cease to rise, everybody becomes eager to buy as much as possible and to restrict his cash holding to a minimum size. For under these circumstances the regular costs incurred by holding cash are increased by the losses caused by the progressive fall in purchasing power. The advantages of holding cash must be paid for by sacrifices which are deemed unreasonably burdensome. This phenomenon was, in the great European inflations of the 'twenties, called flight into real goods (Flucht in die Sachwerte) or crack-up boom (Katastrophenhausse). The mathematical economists are at a loss to comprehend the causal relation between the increase in the quantity of money and what they call "velocity of circulation."" - Mises

Ken Rogoff 

"It's pretty basic. Usually, governments desperate for money start printing currency, lots and lots of currency, and go out buying things."

Modified Dornbusch Overshoot Model

In the Dornbush Overshoot Model the exchange rate for a currency initially drops more than the eventual value in response to a one time monetary increase, so that higher local interest rates provide comparable value to investors.  Local prices are slow to adjust and exchange rates adjust much faster to changes in the money supply.   However, when the monetary injections are repeated, and not a one time thing, then you get repeated "overshoots" and the currency just keeps going down on the forex markets.  Because of the "overshoot" issue it goes down more than linearly with the monetary increase.  The higher cost of imports, and exports being bought up with cheap local currency, eventually overcome the sticky nature of local prices and make prices go up fast.

Interest Rate Below Inflation Rate

If the central bank loans out money at interest rates below the inflation rate then it makes sense for both government and banks to borrow money.  Companies can easily make money if they can borrow from banks at an interest rate lower than the rate prices are going up.  They can borrow and buy just about anything.  Often they buy inputs for their business before they are needed, which can be viewed as increased demand.   The more they borrow the more the inflation rate goes up and the better off the borrowers are.  This can spiral out of control.

Going Galt

 When a government is in trouble it often increases taxes of all kinds and tightens up on the enforcement of existing taxes. Inflation is a tax on those with money.    Government spending is an overhead that the productive parts of the economy have to support in one way or another.    At some point the burdens on an employer can be so great that he is better off to pay the cost to relocate or shut down than to continue in the current environment.   This is called Going Galt.  However, the more employers shut down the smaller the pool of productive people there is for the government  to  extract wealth from, so the higher government increases the various taxes, including inflation.   But the higher the burden on the productive parts of the economy the more business and capital flee that government.   This can spiral out of control, resulting in hyperinflation. 

Attempt to Inflate Asset Prices

     In this explanation of hyperinflation, the central bank wants to inflate asset prices (stocks,  bonds, real estate) to create a wealth effect, so they print lots of money.   However, this increases the prices of the necessities like food and energy more.  Wages do not go up as fast as food prices.   People have to sell assets to get money for necessities.   This causes asset prices to go down in real terms.  This causes the central bank to print more money.   You have a positive feedback loop that gets out of control.

Each Fiat Money is a Bubble

There is no real value to the paper in fiat money, so fiat money is just a bubble.   Hyperinflation is when the bubble pops.

Alternative Method of Defaulting

When a government that can print money has no chance of paying off the bonds it has sold with taxes it can collect, it is effectively bankrupt.   It could default on the debt or it could print money to pay off the debt.   If it prints money to pay off the debt then inflation/hyperinflation makes the value of the currency go down so much that bond holders only really get the value of pennies on the dollar, but legally they were paid off in full.    

Havenstein Moment / Kick the can down the road

Governments that spend much more than they get in taxes will eventually reach a point where the public does not want to lend the government enough money.  At this point, which can be called the Havenstein moment, the government has a choice of either cutting back spending to match the money it can get or getting the central bank to print money and "loan" it to the government.    In the short term it is easier to just print more money than to make the hard spending cuts.   This is sort of "kick the can down the road" approach.  However,  in the long term this results in much more pain.    Once a government starts down the money printing path it is very hard to ever turn back.  Sadly, politicians usually seem to focus on the short term and pick the money printing path.  This eventually leads to

Kuroda and Peter Pan

"the moment you doubt whether you can fly, you cease forever to be able to do it."

Deficits Don't Matter Until They Do

As long as people are loaning the government more and more money, then deficits don't really matter.   But when the public does not want to loan any more money and the government has to get the central bank to print money, then the deficit matters.  But by then it is too late.  Now they are printing money fast.  People are even less interested in buying government bonds.   If they raise interest rates it makes the government more clearly bankrupt, and also makes people less interested in buying bonds.   At this point there is no easy way to avoid high inflation.

Debt Bomb Exploding

When a government that prints its own money sails into the zone of insolvency you can have a debt bomb explode.   If they let interest rates go up, then the interest on the debt takes all the tax money and nobody will buy the bonds.   If they hold the interest rates down, then the yield is so low nobody buys the bonds.  Either way, the central bank ends up monetizing a huge amount of debt in a surprisingly short period.  The explosion of new money makes the money worth far less.

War of Attrition

One group does not want to cut spending and another group does not want to increase taxes.  The stand off results in money printing and inflation till one group gives in.  Thus hyperinflation can be viewed as a war of attrition.

Escape From Liquidity Trap

When a central bank makes money and buys bonds they initially force up the price of bonds and force down the interest rates.  At lower interest rates the velocity of money is lower.  So printing lots of money does not immediately result in inflation (see equation of exchange).  However, the velocity of money also depends on the inflation level.  So if the central bank tries to hold down interest rates forever it eventually results in runaway inflation.  You get to a situation where the more inflation there is, the more the velocity of money goes up, which causes more inflation, and suddenly the economy has escaped from the liquidity trap and has high inflation. 

Double Laffer Overshoot

The Laffer Curve shows how after some point higher tax rates result in lower total taxes collected.   There is also a Laffer Curve for money printing, which is really an inflation tax on those holding money.   After some rate more money printing does not result in more real wealth for the government.  World events and public confidence can shift these Laffer curves around.  Hyperinflation is when the government has overshot the optimal point on both the regular tax rate and the money printing rate.  Any further attempts to increase real revenue for the government fail and make the economy worse off.  The only real fix at that point is to cut government spending, and after all other possibilities have been exhausted, that is how hyperinflation will eventually be halted (maybe years later).

 Bond Traders vs Investors

As a central bank drives up bond prices by buying them it can make sense for a trader to hold bonds.  However, the lower the interest rate the less sense it makes for a long term investor to hold bonds.  So the longer the central bank does this the higher the percentage of bonds are held by traders and the lower percentage held by long term investors.  When bond prices stop going up and start  going down they can do so very suddenly because by that point a very high fraction are held by traders who sell very quickly when prices are dropping.  The sudden flood of sellers makes the central bank have to print money like crazy and buy bonds like crazy or the government won't be able to raise cash by selling bonds.

Central Bank Sucker Punch

For years the market lets the central bankers think they control the markets.  This tricks the central bank in to buying up lots of bonds.  Then very quickly the markets make the bonds and currency worthless.   The central bank is destroyed.

Instability of Velocity of Money

If conditions are such that the price increase from a velocity of money increase results in further velocity of money increase and further price increase then we can say that the velocity of money is unstable.  This spiral can result in hyperinflation.

Modern Monetary Theory and Monetary Realism

In these theories hyperinflation is viewed as a political issue and not a monetary issue.   They will say things like, "Contrary to popular opinion deficit spending and high government debt levels are not the actual cause of a hyperinflation".  They look for some trigger to blame the whole hyperinflation on.  This may be a supply shock, a loss of productive capacity, corrupt or unstable government, or external factors like war.   This will be some reason the government was deficit spending and has high debt levels.  While normally very into detail, even at the level of each debit and credit for monetary operations, when it comes to hyperinflation, they skip over all the detail of the mechanics of hyperinflation.

They always name the initial trigger after the hyperinflation has started and they know to go looking for one.   They do not seem to have any ability to predict hyperinflation ahead of time and never discuss the mechanics of how it works or goes on for so long.   If Japan gets hyperinflation, then they might trace things back to the tsunami and say that was the core cause; however, they could not tell you now if the tsunami will lead to hyperinflation in the future.

These two theories do not seem to help at all in warning when hyperinflation might start nor in really understanding how it works.  All the other theories  above can give you some insight to how hyperinflation happens.     These are more like, "sometimes war causes hyperinflation", without talking about how or any of the steps that go on so you might be able to predict  which wars would cause hyperinflation.    

Since these two  schools of economic thought seem unwilling to explain the mechanics of hyperinflation in their own theories, I will do it for them.   In these theories government bonds are part of the money supply.  Each time the government makes a new bond out of thin air and sells it, they add to the money supply.   In these theories, if the government budget and deficit are out of control, then the money supply is also out of  control.   Note that for this to work in practice, the central bank will have to buy the bonds as the pool of people with money who are foolish enough to buy bonds in the inflating currency soon dries up.  As prices go up the government needs to make more bonds to be able to handle the new higher prices.  However, the more bonds they make the more prices go up.  This spirals out of control, making hyperinflation.

Update:  Cullen responded to this.  

Bond Currency Spiral

If the central government is spending much more than it gets in taxes, and the central bank is buying up bonds, then eventually the currency may start to lose value.   If the currency is going down people may reduce holdings in those bonds but this then forces the central bank to buy more so that the government can keep selling new bonds.  The faster the central bank prints money and buys bonds the faster the currency goes down.  The faster the currency goes down, the faster people rush to get out of bonds.   You can get a death spiral where the currency crashes. 

Blind Men  Describing an Elephant

Above are more than 30 different explanations for hyperinflation, yet they are not contradictory.  They are just different ways of talking about what is going on.  There is clearly some overlap.   It reminds me of the blind men describing an elephant.  At the core of each of these explanations the central bank is funding the government's deficit spending with new money.   Many explanations have some sort of tipping point or feedback loop.  There seem to be many different adverse feedback loops that all operate during hyperinflation.    I challenge anyone to find any error in any of these explanations or any contradiction between them.  

Predicting the Timing

I think that you really can understand the mechanics of hyperinflation if you can understand all these different explanations.   You can understand which currencies have a higher risk of hyperinflation.   However, predicting when hyperinflation starts is a much harder problem.   The reason is that hyperinflation is a positive feedback loop with characteristics similar to positive feedback loops in nature.   You can tell when there is a high risk of an avalanche or volcanic eruption but not exactly when it will start.   I think polling could be used to help predict hyperinflation.  I also think that a simulation could be fitted to historical data and then used to improve prediction of hyperinflation.   

Others Views of Hyperinflation

As I think of other ways to explain hyperinflation I will add them.   If you know of any more, please comment.     I do not mean to leave any theory out.   While I have the names of many other theories (Thanks Tom!), I am finding it hard to locate explanations of hyperinflation for many of them.  If your favorite economic theory is not shown in this list, please let me know how it explains hyperinflation and I will add it.  If  I have not accurately explained hyperinflation in your economic theory, then please comment with a better version.  If your  economic theory does not have an explanation for hyperinflation, then I claim there is a big hole in your theory that someone should work on.

Rejected Explanations for Hyperinflation

Hyperinflation is a complete loss of faith in a currency.  Hyperinflation can go on for years and end in a complete loss of faith in the currency.  However, during those years of hyperinflation, before the end, there is a declining faith but not a complete loss of faith.  Hyperinflation is the process, not the end result.

Drop in productive capacity.    During hyperinflation real productive capacity goes down.  This is because credit is no longer available, price controls make all kinds of shortages, governments usually raise taxes, and it is just hard to do business in a hyperinflation environment.   In most cases this loss of productive capacity is part of a feedback loop but as much an effect of hyperinflation as it is a cause.  There are some hyperinflations where the government deficit can be traced back to a drop in taxes from a drop in productive capacity, but this does not work as a general explanation for hyperinflation.

Political event not a monetary phenomenon.   Yes, politics is the root cause for trouble but the way it causes trouble is by getting the government to deficit spend and get a huge debt that the central bank starts monetizing.  Central banks monetizing out of control government debt is a monetary phenomenon.  Can't we look a little closer at the mechanics of what is going on?  Can't we be a bit more scientific than just saying "hyperinflation is due to politics"?  We are talking about a feedback loop that includes money printing, higher velocity of money, and a rapid drop in the value of the monetary unit.  It is absurd to say "hyperinflation is not a monetary phenomenon".   This is not facing the facts.  It is so wrong it is painful.   Please stop this anywhere you see it.

Caused by foreign currency speculators
Some have claimed that hyperinflation is caused by currency speculators.  There are speculators betting against currencies all over the world.   If they could cause hyperinflation and win big, then all the currencies would have hyperinflation.   A successful speculator figures out that a currency is going to go down before it does and his bets against it.  This does make it happen a bit sooner.  However, speculators always cash out their positions and so undo any net influence they had on the direction the currency was being pushed.  In the long run, foreigner speculators have no ability to make a central bank add zeros to their notes or print so much money that people need wheelbarrows to carry it around.  Also, a country can get hyperinflation even when there is very little foreign currency trading going on.   When politicians and central banks cause hyperinflation they always try to direct public anger away from themselves, but this is just a diversion and not the truth.

A mad man running the central bank could make hyperinflation
A number of people have said that if a mad man was in charge of the central bank then there could be hyperinflation.  This does not help to explain any of the many historical cases of hyperinflation.  It is just someone saying they don't feel there is a risk of hyperinflation without bothering to explain any rational theory of hyperinflation.

Rejected explanations for why hyperinflation can not happen

Any explanation of why hyperinflation can not happen that contradicts the hundreds of cases of historical hyperinflation should be rejected immediately.   For example, if someone says, "the public will never stop buying government bonds", while in hundreds of cases they did stop buying government bonds, then reject immediately.   If someone says, "central bankers would never do that", while there are hundreds of counter-examples where central bankers did participate in hyperinflation, just reject immediately.

Anyone who says hyperinflation can not happen without first explaining their theory for the mechanism of hyperinflation should be asked to explain their theory for the mechanism of hyperinflation used in making their prediction.

I am now offering a prize for additional hyperinflation explanations.  See details of prize here.

The Real Bills Doctrine

In comments on another post Tom Brown linked to work by Mike Sproul on The Real Bills Doctrine.   I think this is well worth understanding.

My interpretation of some key points:

1) Many people think "fiat money" has no backing but really the central bank has assets with real value that back the notes it issues.  By selling these assets it can pull back the money it issues and so support the value of that money.

2) If the bank loans money for 60 days or less and has solid collateral the notes it issues will hold value no matter the quantity issued.

3) If a central bank buys 30 year bonds and interest rates go up then the market value of these bonds can drop so much that it can not withdraw all the notes it has issued.   This then is inflationary.  So interest rates going up when a central bank has long term bonds as assets is inflationary.  This fits with other things I think I understand.

4) The Real Bills theory of money is better for predicting the future value of money than The Quantity Theory of Money.

5) Historically when the assets of the bank have fallen in value the notes have fallen in value as well.  This is inflation.

I think there are often several very different but good ways of thinking about a problem and it is really fun when I can understand more than one way and get the same answer either way.   I think Real Bills is one of these things.  Again, I recommend understanding this.

This Real Bills view is very different from The Equation of Exchange view that I usually use when talking about hyperinflation but I think it is a very valid view.

So let me try to explain hyperinflation from a Real Bills point of view.  If the main assets a central bank has is long term bonds in their own currency  then there can be a dangerous feedback loop.   As inflation or interest rates go up the value of its bonds used as backing go down.  The longer term the bonds are the bigger the drop in value.  But as the value of its backing assets go down so does the value of the currency, and so the value of all bonds in that currency also go down.   The bonds go down much faster than the currency alone as they are a projected future value of the currency.   This, or the fear of more of this, can cause more people to sell.  This can make a feedback loop where the more people sell bonds the worse the backing for that currency, but the worse the backing the more people sell.  This feedback loop can drive the value of the currency lower and lower.

CMMT - Cate's Modern Monetary Theory

CMMT is a very simple model that helps expose the real impact of spending, taxes, and bonds on things like the money supply,  inflation, and hyperinflation.  With a few simplifications it is easier to understand at a high level what is going on.   One big simplification is that the central bank and government are lumped together, as if in one big black box.

Here is the model:
  1. The central bank is part of the government
  2. All government spending is from newly made money (electronic or paper)
  3. All money from taxes is destroyed (electronic or paper)
  4. All money collected from government bond sales is destroyed
  5. All government bonds are paid off with newly made money

If the government is spending more than it is getting from taxes, and it is not selling bonds, then the money supply will go up.

In this model the government can make as much money as it wants, so the only reason for taxes and bond sales is to control inflation.   Since money from taxes is destroyed, taxes reduce the money supply.   Bond sales temporarily reduce the money supply.   As far as the effect on the money supply, a bond sale is equal to a tax and then later a stimulus check.

In this model it is easy to explain hyperinflation.   If the total value of the  bonds is multiples of the money supply, and government spending is twice taxes, then it will be forced to make lots of money if people stop buying bonds.   The money supply will increase because spending is twice taxes, so creation is twice destruction, and because money is created to pay off bonds.   If people get worried that in the future the value of money will be less then they don't want to hold bonds.   However, the faster people get out of bonds the faster the government makes new money to pay off bonds, so once this process starts it is a positive feedback loop that feeds on itself and gets out of control.  If over a year or two people get out of bonds then the money supply will increase very rapidly and you get hyperinflation.   

Another way to think about it is that bond sales temporarily control inflation, but if too many bonds are paid off at the same time it can result in hyperinflation.

Increasing taxes to destroy more money works to fight normal inflation; however, taxes are not up to the job of fighting the rapid death spiral of hyperinflation.  The total debt can be many times the amount of taxes collected in one year, so this rapid monetization of debt is far greater than increasing taxes can cope with.

This CMMT model is just a slight correction to MMT or Modern Monetary Theory.   While they have #1,#2,#3 above they are not consistent in how they treat bonds and do not have #4,#5.    They say all government spending is from new money but then also have the government spending money from bonds.   They say all spending is from new money but also say new money is not spent to pay off bonds.  These errors make standard MMT far more complicated and not match reality.   In particular, hyperinflation really happens but in MMT there is no reason for it.   They have to say that the cause of the hyperinflation of money is outside their theory of money.   This is just silly.  With this little fix hyperinflation is easily explained.  So CMMT is a big improvement over MMT.   CMMT also stands for  Corrected Modern Monetary Theory. :-)

An existing country, like the USA, could do everything it does exactly the same as it currently does and just with changes in accounting it could be like this model.   Recycling tax money to be part of the money spent, instead of printing all new money, should be viewed as just a slight cost saving measure and not fundamentally changing things. 

In the current system the US central bank pays its profits back to the government.   So interest paid on government bonds held by the central bank mostly comes back to the government.   So accounting for these as if they did not exist would not be far off.  We can think of the government as just printing and spending money, instead of borrowing from the central bank, and not be far off.  In reality governments never seem to reduce their  total debt.  We can imagine a black box around the central bank and government and ignore any accounting that goes on inside this box (social security trust fund, money owed by the government to the central bank, etc) as it does not change things in the real world.

This model is just a different way of thinking about what is really going on.  The government can print money, so it really could burn all money collected from taxes and bond sales.   We can match the current system by just saying that money inside the central bank and government is not part of the money supply.  In fact, the definitions for M1, M2, and M3 do not include bank reserves or excess reserves, so this is already matching reality.   Government spending adds to the money supply and bond sales and taxes reduce the money supply.  With this definition we can save a lot of money burning and printing. 

Note that in this model there is no difference between a bank keeping money at the central bank as excess reserves and buying a bond from the government, since the government and central bank are lumped together.   In both cases the money is removed from the money supply and earns interest for the bank.  In this model increasing excess reserves is not increasing the money supply.  This model fits with the low inflation seen over the last few years even as base money in the form of excess reserves has shot up.  

In real life, when things get desperate enough that hyperinflation is a real risk, the independence of the central bank always vanishes.   If the government is spending twice what it gets in taxes and needs the central bank to buy government bonds and fund the deficit it always gets it to do so.   So ignoring the official separation of central bank and government is reasonable when looking at hyperinflation. 

This simple model makes it easier to think about some economic issues and it is reasonable to think about existing countries in these terms.

Two Similar Cases

Imagine the following two similar cases

Case 1:

Imagine that gold is found on US government land equal to all the gold currently held in the world and that it is easy to recover at minimal cost.    The Treasury will soon be selling off rights to this gold and spending the money it makes from the sale.

Case 2:

The Treasury finds a vault with $2 bills that were printed under the Carter administration equal to the total current US base money supply.   After legal challenges, the supreme court determines that the Treasury is free to spend this money.  Since they are spending more than they get in taxes, they start spending it right away.

Similar Results


We should expect that if there is twice the gold in the world the value of each unit will go down relative to other goods.   We should expect that if there is twice the US dollar base money supply that the value of each unit will go down relative to other goods.

Now it could take some time to get to these results but in the end this is what we should expect.

Using common sense we can see the two situations are similar and should have similar results.   After years of training, many economists no longer have common sense.

Economists who think that the central bank can make money without causing inflation think that the central bank can take the money back out of circulation.  Sometimes this is true, but not always when it is buying government debt and the total government debt is growing fast.   The central bank can sometimes find there are no buyers for government bonds.  Forcing a government that was spending twice what it gets in taxes to tighten its budget so much that it can start paying down its debt is not really within the power of a central bank.  The people running the central bank are appointed by the government and can be changed.  The laws the central bank operates under are made by the government and can be changed.   In practice, the central bank will often not be able to withdraw the money it has created.   When this happens, instead of admitting their error, the economists say the people in government or the central bank were corrupt or incompetent.  They ignore all the data that contradicts their theory.  That is not how real science works.

You can also look at it as the Treasury spends money it gets from bonds it makes out of thin air and the central bank buys bonds with money made out of thin air.    Together this lets the government spend money out of thin air.

Zooming Past Inflation Target

In April Japan's central bank announced a new policy where they would pretend that monetization was temporary so they could ignore the "bank note rule" that limited money creation and claim they were not funding the government deficit.   But Japan is spending twice what it gets in taxes and will not be paying down debt anytime soon, so it is not really temporary, so they are really making money to fund government spending.  This is bad.

Since then the  reported Japanese inflation has been going up each month:

            Reported      Change
Apr:   -0.7%
May:  -0.3%               0.4%
Jun:     0.2%               0.5%
Jul:      0.7%               0.5%
Aug:    0.9%               0.2%
Sep:    1.0%               0.1%
Oct:    1.1%                0.1%
Nov:   1.5%                0.4%

Inflation is up 2.2% in 7 months for an average of 0.31% per month.  Starting from 1.5% we can use 0.31% per month to estimate a rate of 2.12% in 2 more months.  This is over Japan's target rate of 2%.   Given that they have no plans to slow down the rate of money creation for almost 2 more years, why would inflation stop going up 2 months from now?  Looks to me like Japan will soon be zooming past their inflation target.

As a country heads into hyperinflation people cut back on optional things, which makes the prices on these not go up as fast.   Necessities like food will go up faster than the average rate of inflation.  This seems to be happening in Japan.

Given the rate a which Japan is making money, I think there is more chance of averaging more than a 0.4% increase per month than less than that.  I think they are close to the point where things start to spiral out of control.  However, the lasr 2 months have not shown this.

Let us look at the choice facing the central bank if 2 months from now it has passed its 2% inflation target.   It has been making money at a furious pace to buy bonds and keep interest rates down.   If it stops then interest rates will shoot up.  Even with interest rates very close to zero a huge part of the government's tax collection goes to paying interest.   If interest rates shoot up then the government will clearly be broke and people will not want to buy or hold Japanese bonds.   The government would fail.   So they can't stop buying.  There is no real choice.   This is when hyperinflation comes, when money creation is really out of control.

If I am right, then the rate of money creation will go up as more and more bond holders get worried and get out, and inflation will go up faster and faster.
