U.S. consumer prices rose 0.4 percent in August 2026 from the previous month. Data released by the Bureau of Labor Statistics on September 11 showed annual inflation at 3.4 percent, unchanged from July. The consumer price index excluding food and energy increased 0.3 percent monthly and 2.4 percent over twelve months. Reuters, the Associated Press and The Wall Street Journal separately confirmed the headline figures.
Gasoline drove much of the monthly rise
The official report showed gasoline prices climbing 3.9 percent in August, accounting for more than one third of the increase in the overall monthly index. Several service categories also moved higher. Airline fares rose 2.7 percent, lodging away from home increased 2.4 percent and the communication index gained 2.3 percent. The medical care index, by contrast, declined 0.2 percent for the month.
Housing costs remained important for household budgets. Owners’ equivalent rent and the rent index each increased 0.2 percent in August. Over the latest twelve months, the shelter index rose 3.0 percent. The 2.4 percent annual increase in core prices indicated that the inflation picture was not limited to energy, even though gasoline made a large contribution to the monthly headline movement.
How to read the figures
The monthly and annual numbers answer different questions. The 0.4 percent monthly change compares August prices with July. The 3.4 percent annual rate compares August 2026 with August 2025. The seasonally adjusted monthly figure and the unadjusted twelve-month rate appear in the same report but are designed for different types of comparison.
BLS explains that the CPI measures the average change in prices paid by urban consumers for a basket of goods and services. It does not reproduce every household’s personal experience. The inflation faced by an individual family can differ from the national average depending on energy use, housing arrangements, transportation and the products it purchases.
The report said food prices increased 0.3 percent for the month, while the energy index rose 2.8 percent. Prices for used cars and trucks gained 0.4 percent and new vehicles increased 0.3 percent. Apparel and recreation were unchanged. The distribution shows why the headline measure should be read as a combination of many separate price movements.
Why the report matters for the Fed
Reuters, AP and The Wall Street Journal assessed the data in the context of the Federal Reserve’s approaching policy meeting. Although the headline rate matched expectations, the 0.3 percent monthly increase in core prices kept the interest-rate debate active. One inflation report alone does not determine the Fed’s decision. Employment, wages, growth and financial conditions are also part of the policy assessment.
Market pricing and economists’ forecasts can change quickly and are not official policy decisions. The report therefore focuses on the economic information contained in the CPI release rather than claiming certainty about the central bank’s next move. Any rate decision can be confirmed only through the Federal Reserve’s official statement after its meeting.
What comes next
The BLS release calendar says the September 2026 consumer price report is scheduled for October 14, 2026. That update will show whether the energy and service-price movements recorded in August continued. The verified conclusion from the current report is straightforward: headline CPI rose 0.4 percent monthly, the annual rate remained 3.4 percent and annual core inflation was measured at 2.4 percent.
