GMX reports that the US October CPI will be released tomorrow at 8:30 AM Eastern Time. The market expects the overall CPI to rise by approximately 0.3% month-over-month, and the core CPI to rise by approximately 0.2% month-over-month. September's overall CPI rose by 0.6%. Due to a data gap caused by the 2025 government shutdown, there will be no year-over-year data this time. Futures markets indicate a 77% probability of an interest rate hike on December 9th. The S&P 500 is projected to have its worst week since April 2025. AI Interpretation: This CPI data release is a crucial window for the market to assess inflation stickiness. Market expectations for core inflation reflect a cautious attitude towards the process of price decline. The current high probability of an interest rate hike indicates 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 will have a decisive impact on US stock market volatility.
