Why hasn't the interest rate been lowered yet?
Other Western countries have already lowered their interest rates. The United States doesn't not want to lower rates, but it can't. Over the past few years, money from all over the world has been flowing to the United States to earn interest, and the principal plus interest has likely doubled by now. This money is sitting in American banks earning interest. Once they lower the interest rate, won't everyone withdraw their funds? The problem is, what can the U.S. give them in dollars? The government has already spent all that money. Once the interest rate is lowered, international capital will return home, and banks will immediately face a run and be emptied. How many banks do you think will go bankrupt in the U.S.?
The issues with U.S. debt are minor. Over the years, an immense amount of capital has flowed into the U.S. due to interest rate hikes. After more than three years of compound interest, the real problem is what the U.S. can offer to pay back the principal and interest. Originally, the U.S. planned to explode China and use the plundered assets not only to pay everyone’s principal and interest but also to make a large profit for themselves. As a result, the money has been spent countless times, and China hasn't collapsed. So what now? The U.S. itself does not have the ability to pay back the principal and interest, which is why it is still dragging its feet on lowering interest rates. The longer they hold off on lowering rates, the more the interest accumulates, and the more they are afraid to lower rates... a vicious cycle.
Most likely outcome: Gradual rate cuts + secretly printing money to dilute debt (a disguised default).
