Trump has been emphasizing that the Federal Reserve should lower interest rates, and there are many reasons behind this.

First, lowering interest rates makes loans cheaper. Whether for businesses or ordinary people, when the cost of borrowing is lower, they are more willing to invest and spend, which naturally stimulates the economy. Trump has always been concerned about the performance of the U.S. economy, especially in terms of employment and growth. He believes that lowering interest rates is a "quick-acting" remedy.

Secondly, the U.S. government has a large amount of debt, and every year it has to pay a significant sum just in interest. When interest rates drop, interest expenses decrease, giving the government more financial flexibility, which is a good thing for the budget.

Moreover, low interest rates are favorable for the stock market; investors are happy, and when the stock market rises, everyone feels hopeful about the economy. This is also a kind of "report card" for Trump, as he often uses stock market performance to make his points.

Additionally, during trade wars or when facing global economic turmoil, lowering interest rates becomes a form of "self-protection" to stabilize the domestic economy.

Finally, let’s not forget that Trump is a political figure. When the economy is good, voters are happy, and his approval ratings naturally rise. For him, lowering interest rates is not just an economic policy, but also a political strategy.

In summary, Trump hopes that by lowering interest rates, he can strengthen the economy, lighten the debt burden, stabilize the market, and also gain a political advantage.
