Short version on why interest rates will no doubt go back down.
Our national debt is financed via short term notes. They constantly get rolled over and doing so at high interest rates like now is killing us. We have spent over $1T in 2024 just servicing our debt. The solution is stop spending money or lower interest rates so we can finance it at a lower rate. We all know which one of those will win.
Politicians in both parties need the stock market to do well. People equate it with the economy now, which is dumb but they do. A more serious reason is retirement. The middle class depends on their 401K to retire. Low interest rates help the market, so as soon as it stutters for a prolonged period, the rates will start to be slashed.
