September consumer inflation reaches 3.7% over 12 months
The Bureau of Labor Statistics reported a 0.6% monthly increase and a 3.7% annual increase in the September CPI.
The U.S. Bureau of Labor Statistics (BLS) reported the Consumer Price Index (CPI) rose 3.7% in the 12 months to September 2026, compared with 3.4% in the 12 months to August. That is 0.3 percentage point faster, not a 0.3% jump in the overall price level.
The number is not the whole story.
The Consumer Price Index (CPI) for All Urban Consumers measures changes in the prices of a representative basket of goods and services purchased by urban consumers; it is not the individual inflation rate of every household.
September 2026 prices were 3.7% above September 2025, compared with a 3.4% annual increase reported for August. That is an acceleration of 0.3 percentage point. Prices rose 0.6% during September on a seasonally adjusted monthly basis, versus 0.4% in August.
Slower inflation would mean prices rising less quickly, not necessarily falling. The monthly jump also reflects unusually large gasoline increases; categories and individual household budgets can diverge.

Why it matters
The year-over-year CPI rate compares average price levels with the prior September; it does not imply all household budgets face identical increases.
What remains unresolved
Will the October CPI report on November 10 show the same pattern?
