Core PCE Price Index
Published:
A U.S. measure of underlying consumer inflation based on personal consumption expenditures, excluding food and energy.
Full explanation
The Core PCE Price Index measures changes in the prices paid for goods and services by U.S. consumers, excluding food and energy. Removing those categories, which can move sharply from month to month, is intended to give a clearer view of underlying consumer inflation. The U.S. Bureau of Economic Analysis publishes it monthly as part of the Personal Income and Outlays release, with monthly and annual rate-of-change measures commonly followed.
Why traders watch it
It is closely watched because it is a prominent underlying-inflation measure used in assessing the U.S. inflation outlook and monetary-policy conditions. Surprises can affect expectations for Federal Reserve policy, U.S. Treasury yields, and the U.S. dollar.
Market interpretation
- U.S. dollar
- A material surprise versus consensus can lead to a reassessment of expected U.S. monetary-policy settings and increase short-term price volatility.
- U.S. Treasury market
- The result can affect expectations for future policy rates and, in turn, Treasury yields.
- Major FX pairs
- Pairs involving the U.S. dollar may react as relative interest-rate expectations adjust.
Stronger vs weaker outcomes
A higher-than-expected reading may be interpreted as evidence of firmer underlying inflation and can prompt markets to reassess the likely path of policy rates. A lower-than-expected reading may be interpreted as evidence of easing underlying inflation pressure. The market response depends on the surprise relative to expectations and the wider economic backdrop.
A higher-than-expected result may be viewed as firmer underlying inflation, potentially leading markets to reassess the expected path of U.S. interest rates.
A lower-than-expected result may be viewed as softer underlying inflation, potentially leading markets to reassess the expected path of U.S. interest rates.
The reaction usually depends on how far the release differs from expectations, whether the surprise is in the monthly or annual measure, and how it fits with other inflation and activity data.
Typical volatility
High. The index excludes food and energy but is not a complete measure of all consumer price pressures. Results can be revised, and the monthly and annual changes can convey different messages about inflation momentum.
Trading considerations
- Check whether the calendar value is the month-over-month or year-over-year change before comparing it with forecasts.
- Compare the core reading with the headline PCE price index and the accompanying personal income and consumer spending figures.
- Monitor revisions to prior months as well as the newest result.
- Expect liquidity conditions and bid-ask spreads to change around a major U.S. data release.
- Consider the release alongside other inflation measures rather than treating one observation as a complete inflation signal.
