U.S. inflation accelerated in September 2026, with the Consumer Price Index (CPI) rising 0.6% for the month and annual inflation reaching 3.7%, up from 3.4% in August, according to the U.S. Bureau of Labor Statistics. Surging energy costs drove the increase, as gasoline prices jumped 9.1% during the month and 34.2% over the past year.
Core inflation, excluding food and energy, rose 0.3% monthly and 2.6% annually. Shelter costs continued to increase, while overall food prices remained unchanged.
The renewed rise in inflation complicates the Federal Reserve’s efforts to achieve its 2% target and could influence future interest-rate decisions. Investors will be watching energy prices and upcoming economic data for signals about the outlook for interest rates, bond yields, and financial markets.
