In the world of financial markets, the policy adjustments made by the Federal Reserve (Fed) have significant impacts on the global economy. Particularly decisions regarding interest rates directly influence investors' asset allocation and market sentiment. Lately, as the US August Consumer Price Index (CPI) inflation report approaches, the market's anticipation for a potential interest rate cut by the Fed in September has become a focal point. According to the leading global financial derivatives trading platform, CME Group's FedWatch tool, the market generally believes that the Fed will take action to lower interest rates. Specifically, the probability of a 25 basis point rate cut stands at 67%, indicating that this possibility is considered large; simultaneously, the probability of a 50 basis point rate cut is 33%, though it falls short of the former, it still suggests that some market participants expect more accommodative monetary policy. This analysis reflects the current market's complex sentiments and uncertainty about the economic outlook. As the CPI data is released, the gap between market expectations and actual outcomes may trigger market fluctuations, and investors should closely monitor related information to make appropriate decisions.
