For years now central banks around the world have been making new money and buying bonds to drive up the price of bonds and down interest rates. In the short term central banks can make interest rates go down, but in the long run all the new money they make while doing this will cause interest rates to go up. I think we might be going from short run to long run.
Another way to look at it is that central banks have spent trillions driving up the prices for bonds. This has made bond bubbles all over the world. At some point these bond bubbles will pop. We may be seeing the start of that pop now.
Interest rates in many countries have been going up fast the last couple months and bond prices are falling.
