Under the current economic situation, the possibility of the Fed lowering interest rates in September is increasing. As the chairman of the Fed, Powell has always formulated monetary policy based on employment conditions and inflation levels. However, the current economic conditions are different from the past, making the decision to lower interest rates more complex.

Trump's tariff policy has had a profound impact on the economy, making traditional decision-making models potentially unsuitable. In this context, Powell may consider implementing interest rate cuts to address potential economic risks.

In addition, considering that Powell's term is coming to an end, he may wish to conclude his career with a positive policy action. By cutting interest rates in a timely manner, he can not only demonstrate his keen judgment of the economic situation but also avoid potential criticism in the future for not taking action in time, which could lead to stagnation in economic growth.

Considering these factors, the possibility of the Fed lowering interest rates in September is indeed high. However, the final decision will still depend on the economic data and global financial market performance at that time. In any case, Powell's decision will have a significant impact on the U.S. economy and even the global economy.
