2025年12月美国CPI数据点评：扰动结束后，美国Q1通胀料将反弹

Group 1: Inflation Overview - The overall CPI for December 2025 in the U.S. was +0.31%, in line with expectations, while core CPI was +0.24%, below the expected +0.30%[3] - Year-on-year CPI increased by 2.68%, matching expectations, while core CPI rose by 2.64%, slightly below the expected 2.70%[3] - The weaker-than-expected core CPI was primarily influenced by declines in used car prices, a price war among telecom companies, and seasonal factors, which are expected to have a short-term impact[3] Group 2: Economic Projections - For Q1 2026, there are upward risks to U.S. non-farm payroll and inflation data due to fiscal and monetary impulses, as well as seasonal factors[2] - The fiscal impulse for Q1 2026 is estimated to boost U.S. GDP by 2.79%, largely due to the end of government shutdowns[2] - Cumulative interest rate cuts of 75 basis points since September 2025 are expected to stimulate the economy in Q1 2026[2] Group 3: Market Reactions - Following the release of the weaker core CPI, market expectations for interest rate cuts increased, leading to rises in U.S. stocks and gold, while U.S. Treasury yields and the dollar index fell[3] - However, asset prices later partially retraced the volatility caused by the monetary easing trades[3] Group 4: Risk Factors - Potential risks include unexpected policy actions from Trump, excessive interest rate cuts by the Federal Reserve leading to inflation rebound, and prolonged high interest rates causing liquidity crises in the financial system[4]
