Core PCE is the Personal Consumption Expenditures price index excluding food and energy, the Federal Reserve's preferred gauge of underlying US inflation. It strips volatile food and energy prices to reveal the persistent trend that informs the FOMC's 2% target, measured on the broad PCE basket rather than the narrower CPI.
How it works
The Bureau of Economic Analysis constructs the PCE price index from national-accounts consumption data, then removes food and energy components to isolate trend inflation. Unlike CPI, PCE uses a chain-weighted formula that captures substitution between goods and incorporates broader coverage (e.g. employer-paid healthcare), which structurally biases it below CPI by roughly 30-40 basis points.
Why it matters now
With core PCE printing in the high twos through 2025 — above the Fed's 2% target — the gauge is the central anchor for how restrictive the FOMC keeps policy and how markets price the terminal rate and cut path. Tariff pass-through risks keeping it sticky into 2026.
Example
In 2022 core PCE peaked near 5.6% year-on-year, prompting the Fed's most aggressive tightening cycle in four decades; by late 2024 it had cooled toward the high twos, but remained stubbornly above the 2% target the FOMC reaffirmed in its longer-run framework.
Frequently asked
- What is core PCE?
- Core PCE is the Personal Consumption Expenditures price index excluding food and energy, the Federal Reserve's preferred measure of underlying US inflation. Published monthly by the Bureau of Economic Analysis, it strips volatile food and energy components to expose the persistent trend the FOMC targets at 2% on a year-over-year basis.
- Why does the Fed prefer core PCE over core CPI?
- The Fed prefers core PCE because its chain-weighted formula captures consumer substitution and its broader coverage—including employer-paid healthcare—better reflects actual spending. These structural differences make core PCE run roughly 30-40 basis points
Glossary · 25bp / bp
A basis point (bp) is one-hundredth of a percentage point (0.01%); 25bp equals 0.25 percentage points, the conventional increment of a single central-bank rate move. Policymakers quote rate changes, yields, and spreads in basis points to avoid the ambiguity of percentage-of-a-percentage phrasing.

- How does core PCE differ from CPI?
- Core PCE and CPI differ in formula, coverage, and weighting. PCE uses a chain-weighted (Fisher) index that adjusts for substitution between goods, while CPI uses fixed weights updated less frequently. PCE also covers spending made on consumers' behalf, like employer healthcare, giving it a larger services share that structurally biases it below CPI.
- What is core PCE running at now?
- Core PCE has printed in the high twos (percent year-over-year) through 2025, above the Fed's 2% target. After peaking near 5.6% in 2022, it cooled through 2023-2024 but stalled above target. Tariff pass-through risks keeping it sticky into 2026, shaping how restrictive the FOMC holds policy.
- Did core PCE drive the Fed's 2022 tightening?
- Core PCE peaking near 5.6% year-on-year in 2022 was the central justification for the FOMC's most aggressive tightening in four decades, lifting the funds rate from near zero to over 5%. Because the gauge anchors the Fed's reaction function, its persistence above 2% kept policy restrictive well into 2024-2025.
