US Core Consumer Price Index YoY
Published:
A monthly measure of underlying US consumer-price inflation that excludes food and energy.
Full explanation
US Core Consumer Price Index YoY measures the annual change in prices paid by urban consumers for a broad basket of goods and services, excluding food and energy. It is often called core CPI because food and energy prices can move sharply from month to month. The Bureau of Labor Statistics publishes the all-items-less-food-and-energy index as part of its monthly Consumer Price Index release. The year-over-year rate compares the index with the same month a year earlier.
Why traders watch it
It is widely followed as a gauge of underlying US consumer-price pressure. Surprises can affect expectations for Federal Reserve policy, Treasury yields, interest-rate markets and USD sentiment.
Market interpretation
- USD
- Unexpected results can prompt repricing of the US interest-rate outlook and changes in dollar sentiment.
- US Treasury yields
- Yields may react as investors reassess the likely path of inflation and monetary policy.
- Equity and risk markets
- The release can affect broader risk sentiment through expected financing conditions and discount rates.
Stronger vs weaker outcomes
A higher-than-expected reading may be interpreted as firmer underlying inflation pressure, while a lower-than-expected reading may be interpreted as softer pressure. The reaction can also depend on headline CPI, the details of price changes, revisions and the broader policy backdrop.
A higher-than-expected core CPI reading may be viewed as evidence of firmer underlying inflation pressure and can lead markets to reassess the expected path of monetary policy.
A lower-than-expected core CPI reading may be viewed as evidence of softer underlying inflation pressure and can lead markets to reassess the expected path of monetary policy.
Higher-than-expected core CPI may signal firmer underlying inflation pressure; lower-than-expected results may signal softer pressure.
Typical volatility
High. Core CPI excludes food and energy, so it is not a complete measure of changes in all consumer prices. Seasonal adjustment, shelter and services components, base effects, and comparisons with other inflation measures can influence interpretation.
Trading considerations
- Compare the annual result with the monthly core CPI change and the headline CPI reading.
- Review the composition of the release, especially services, shelter and goods components.
- Account for base effects when interpreting year-over-year changes.
- Expect spreads and short-term volatility to potentially increase around the scheduled release time.
- Consider revisions, seasonal adjustment and other inflation indicators rather than relying on one reading alone.
