According to CoinMeta, gmx indicates that the U.S. CPI for October will be announced tomorrow at 8:30 a.m. Eastern Time. The market expects the overall CPI to rise by about 0.3% month-on-month, with the core CPI rising by about 0.2% month-on-month, and the overall CPI in September to rise by 0.6%. Due to a data gap caused by the government shutdown in 2025, there are no year-over-year data this time. The futures market shows that the probability of a rate hike on December 9 is about 77%. The S&P 500 index recorded its worst week since April 2025. The current probability of a rate hike is high, indicating a strong consensus in the market regarding a tightening monetary policy path. This data will directly determine the tone of the Federal Reserve's subsequent interest rate decisions and have a decisive impact on the volatility of U.S. stocks.
