Internet reports that Federal Reserve Chairman Powell said on Wednesday that the market's expectation that the Fed will intervene to calm fluctuations may be wrong. Asked if the Fed would intervene in response to a sharp decline in stocks, Fed Chairman Powell said: "My answer is no, but I will explain." Powell said at a conference in Chicago: "I think the market is digesting the current situation, and the market is dealing with a lot of uncertainty, and that means volatility. "Powell said that given that President Trump's tariff system is undergoing tremendous changes, it is understandable that the market will encounter difficulties. He also explained that it is difficult to know in real time what is causing the trouble. Powell said: "I have a lot of experience with major market fluctuations, such as the bond market. People usually form an idea, look back two months later, and find that the original idea was completely wrong. So it's too early to tell what happened in the market." For now, he pointed out that part of the market turmoil stems from hedge funds reducing leverage or debt, adding: "In the short term, you may continue to see market volatility."
