Inflation reports show several numbers. Here is what each means, using September 2026 data.
Headline
All items, including food and energy: 3.7% from a year earlier. It is what households feel and is volatile because of energy.
Core
Excludes food and energy: 2.6% year over year, up from 2.4% in August. Core is a better guide to underlying trend.
Supercore
Services excluding housing, a measure many economists use as a read on wage-driven inflation. InvestingLive reported it at about 3.13% from a year earlier, up from about 3.02%.
Why the Fed cares
The Fed worries when inflation is broad rather than driven by one category. Rising supercore suggests prices are climbing beyond energy. Cleveland Fed President Beth Hammack said in October she saw inflation pressures as relatively broad-based.
How to use this
Compare all three. If headline is high but core and supercore are calm, the shock may fade. If all three rise, policy is likely to stay tight.
