Trump and the Federal Reserve have been spraying each other for a long time. Trump hoped that the Federal Reserve would cut interest rates, while the Federal Reserve repeatedly said that it would not. This time, Trump said that Powell, the chairman of the Federal Reserve, was a fool and should go to the Federal Reserve. Powell countered by saying that the policy framework of the Federal Reserve should not depend on who serves as chairman. In other words, whoever becomes the chairman cannot cut interest rates. One of the core reasons why Trump wants to cut interest rates is that the interest rate of US debt is too high now. After the interest rate cut, the interest rate on US bonds can be reduced. One of the important reasons why Powell is unwilling to cut interest rates is that there is too much inflationary pressure in the United States. After the interest rate cut, it may further push up inflation. These two people, one in charge of the federal government and the other in charge of inflation, stand from their own perspectives and criticize each other. The interest on US bonds is borne by the federal government, while the pressure of inflation is borne by the Federal Reserve. From the perspective of the United States as a whole, it is now in a dilemma. It's difficult to both want low interest rates on US bonds and prevent inflation from being pushed up.
