Frequently asked questions

What is the current core CPI inflation rate?

Core consumer prices (CPI excluding food and energy) rose 2.6% over the 12 months ending September 2026, up from 2.4% in August 2026. The core CPI-U index stood at 339.287 (1982-84 = 100). A year earlier (Sep 2025), the reading was 3.0%.

Why does core inflation exclude food and energy?

Not because they don't matter, but because their prices jump around with weather, harvests and oil markets, and those swings often reverse. Stripping them out shows the more persistent trend that monetary policy can influence.

What is the biggest part of core CPI?

Shelter — rent and owners' equivalent rent — is the largest component. Shelter inflation reacts slowly because leases reset only about once a year, so core CPI tends to trail changes in market rents and home prices.

Which matters more to the Fed, core CPI or core PCE?

The Fed's 2% goal is set in terms of PCE inflation, and policymakers pay particular attention to core PCE as a guide to the trend. Core CPI is released earlier and moves markets, and much of the PCE price index is built from CPI data.
