What does sticky core PCE mean?

Sticky core PCE is the inflation measure the Fed uses to judge underlying price pressure. It strips out food and energy (which bounce around) AND further filters to prices that change slowly. If sticky core PCE is high, inflation is structurally embedded. Not just a one-off shock.

Why does the Fed prefer PCE over CPI?

PCE is broader (covers all consumer spending, not just urban basket), adjusts faster to consumer substitution behavior, and reweights frequently. The Fed has formally targeted PCE since 2000.

THE TERM

Technical vs Plain English.

TECHNICAL DEFINITION

Sticky Core PCE. The Personal Consumption Expenditures price index, excluding food and energy components (core), further filtered to include only categories whose prices change infrequently (sticky). Compiled by the Atlanta Federal Reserve from BEA PCE data. Used by FOMC members as a leading signal of persistent inflation pressure as opposed to transitory shocks. Sticky categories include rent, services, insurance, and medical care. Flexible categories (gasoline, food, used cars) move daily and are excluded.

PLAIN ENGLISH MODE · ON

The Fed cares about inflation that's stuck in the system, not inflation that's a one-off shock. So they look at PCE (a broad inflation measure), strip out food and gas (which bounce around), and then strip out anything else that changes prices fast (used cars, electronics). What's left. Rent, insurance, doctor's visits. That's "sticky." If those are still going up, inflation is real and structural. The Fed keeps rates high.

WHY YOU SEE IT IN THE NEWS

Context in 60 seconds.

Every Fed presser, every CPI/PCE release day, you'll see "sticky core PCE" cited. The reason: it's the measure that decides whether the Fed pivots dovish. The Fed publicly targets 2% PCE inflation. But within the FOMC, members watch sticky core PCE because it tells them whether the 2% target is achievable without a recession.

The numbers to know:

Sticky core PCE peaked at 6.5% in early 2023
Came down to 3.8% by end of 2024
Currently around 2.6% (mid-2026)
Fed wants under 2.5% for sustained periods before cutting confidently
The "last mile" (3% to 2%) is the hardest because rent and services are sticky

So when you read "Powell cited continued progress on sticky core PCE". Translate: inflation in the categories that don't usually budge is finally moving in the right direction, which means the Fed is closer to feeling safe about cutting rates. When you read "sticky core PCE remains elevated". Translate: inflation is structurally embedded, the Fed will hold rates higher for longer.
