US Core PCE Inflation (Year-over-Year %)
US Core Personal Consumption Expenditures price index year-over-year percentage change from 2001 onwards. The Federal Reserve's preferred inflation gauge, the series the FOMC explicitly references in its 2 percent symmetric target. Core PCE excludes food and energy and is generally smoother and lower than headline CPI inflation. Released monthly by the BEA at the end of each month; preceded by CPI by roughly two weeks. AUD-trader framing on Fed reaction function and US/AUD rate differential implications.

What is Core PCE?
The Personal Consumption Expenditures (PCE) price index measures the prices US households pay for goods and services, including those covered by employer health-care plans, Medicare, Medicaid, and other third-party expenditures that CPI excludes. Core PCE strips food and energy components for a less noisy underlying trend.
The Fed's strategic statement (re-affirmed in August 2020 under the new flexible average inflation targeting framework) commits to a 2 percent symmetric Core PCE target over the medium term. "Symmetric" means the Fed cares equally about inflation overshoots and undershoots; "flexible average" means the Fed can tolerate above-target inflation for a period to make up for prior undershoots.
Core PCE vs Core CPI
| Attribute | Core PCE | Core CPI |
|---|---|---|
| Publisher | BEA | BLS |
| Release timing | End of month | 13th of month |
| Coverage | Broader (includes 3rd-party spending) | Out-of-pocket only |
| Weighting | Chain-weighted (substitution) | Fixed basket (Laspeyres style) |
| Housing weight | ~15% | ~33% |
| 2022 peak YoY | 5.4% (Feb 2022) | 6.6% (Sep 2022) |
| Typical gap | 0.3-0.5 pp lower | 0.3-0.5 pp higher |
| Fed target | 2% explicit | None (referenced) |
Trader takeaway
- Direction over level. Core PCE trending down toward target is dovish-Fed regardless of absolute level. Core PCE trending up away from target is hawkish-Fed.
- Three-month annualised vs YoY. Bond traders often look at the 3-month annualised rate to spot inflection earlier than the noisier YoY series. A 3-month rate well below the 12-month rate signals disinflation is accelerating.
- Supercore PCE. Powell highlights "supercore PCE" (core services ex-housing) as the residual sticky-inflation component. Watch this for the late-cycle disinflation read.
- AUD/USD positioning. Pre-PCE volatility is lower than pre-CPI because CPI already provided most of the information. But surprises (rare given the predictable input from CPI) can move AUD/USD 30-50 pips.
Methodology
- Source. Computed locally from FRED series PCEPILFE (Core PCE price index, monthly seasonally adjusted).
- Formula. YoY% = (PCEPILFE this month / PCEPILFE same month prior year - 1) × 100.
- Earliest valid datapoint. Jan 2001 (12 months after series start in this dataset).
- Recession shading. NBER-dated US recessions.
- Static-first. Snapshot preserved if FRED is unreachable on build.

Frequently asked questions
Core PCE is the Personal Consumption Expenditures price index excluding food and energy components. It is published monthly by the Bureau of Economic Analysis as part of the Personal Income and Outlays release. The Federal Reserve targets Core PCE at 2 percent year-over-year symmetric (since 2012). The 'core' adjustment excludes the most volatile components (food + energy) to reveal underlying inflation pressure. FRED series ID is PCEPILFE.
Four reasons documented in the FOMC's strategic statement: (1) PCE has broader scope (covers all consumption including healthcare paid for by employer plans and government programs, where CPI only covers out-of-pocket consumer spending); (2) PCE has a chain-weighted formula that adjusts for substitution between goods (when chicken gets cheap relative to beef, consumers buy more chicken); (3) PCE is less affected by housing methodology, which dominates CPI; (4) PCE data has been historically less volatile and easier to forecast. Net effect: Core PCE typically runs 0.3-0.5 percentage points below Core CPI, reflecting these methodological differences.
Monthly, end of the month, typically the last Friday at 8:30 ET, as part of the Personal Income and Outlays release. The data covers two months prior (e.g. the August 2026 release covers June 2026 prices). Core PCE is released roughly two weeks AFTER CPI, so CPI is the higher-frequency leading indicator the market reacts to first. PCE is the data the Fed itself flags as definitive.
Through the Fed reaction function. When Core PCE runs above 2 percent, the Fed has hawkish bias; when it runs below 2 percent for extended periods, dovish bias. The Fed's published Summary of Economic Projections (SEP) every quarter forecasts the Core PCE path explicitly. AUD/USD positioning around month-end PCE prints typically reflects the prior CPI print's direction; large PCE surprises (rare) can extend the move. The RBA itself references Core PCE in policy commentary because Australian inflation cycles typically lag the US by 3-6 months.
Core PCE YoY peaked at 5.4 percent in February 2022, well below the headline CPI 9.1 percent peak in June 2022 but still the highest Core PCE reading since the early 1980s. The gap between Core PCE and headline CPI in 2022 was driven primarily by the energy shock (Russia-Ukraine) and food inflation that Core PCE excludes. By early 2026 Core PCE was approaching the 2 percent target, allowing the Fed to start cutting rates in September 2024.
No. The 2 percent target is symmetric, meaning the Fed cares equally about inflation 1 percentage point above vs below the target. The Fed cuts when (a) Core PCE is trending below 2 percent OR (b) the labour market is weakening enough that the dual mandate (price stability + maximum employment) requires accommodation. The September 2024 first cut happened with Core PCE at 2.7 percent because labour-market data softened and the Fed wanted to ease before unemployment rose further. This is consistent with the framework even though the headline number was above target.
