US core inflation rose to 2.6% in the reference period of September 2026, the figure published at 12:30 GMT on 14 October 2026. The reading came in above the market forecast of 2.5%, and it was higher than the previous period’s 2.4%.
What the number measures
Core inflation tracks the annual change in consumer prices while stripping out food and energy, which tend to swing sharply from month to month. Economists watch it because it gives a steadier view of underlying price pressure than the headline rate. A reading of 2.6% means prices for the goods and services in the measure were 2.6% higher than a year earlier.
The gap to forecast was small, but it ran in one direction. Coming in above expectations means price growth was firmer than analysts had assumed. The move from 2.4% to 2.6% is a rise against the previous period, and that is the comparison that shows the trend.
Context
For the wider picture, the annual US inflation rate stood at 3.4% in the August 2026 reading, a monthly statistic that covers a different period and a different measure from the core figure. The two are not directly comparable.
