About CPI-U All Items — United States
DEFINITION
The Consumer Price Index for All Urban Consumers (CPI-U), All Items, published monthly by the Bureau of Labor Statistics. Measures the average change in prices paid by urban consumers for a market basket of consumer goods and services. The headline US inflation gauge.
WHY THIS INDICATOR MATTERS
Headline CPI is the most-watched inflation print globally. It directly influences Fed policy expectations, real-yield calculations, TIPS pricing, and inflation-linked cost-of-living adjustments (Social Security, federal pensions). A hot CPI print can trigger same-day cross-asset repricing of significant magnitude.
MARKET IMPACT
| Market | Direction | Strength | Rationale |
|---|---|---|---|
| US Treasuries | negative | high | Yields spike on upside surprises |
| USD | positive | high | Hawkish Fed pricing on hot CPI |
| S&P 500 | negative | high | Discount-rate shock + tightening fears |
| Gold | mixed | medium | Hedge vs. real-yield response cross-cancel |
FAQ
- What is the difference between headline and core CPI?
- Headline includes food and energy; core excludes them to reduce volatility and reveal underlying trend.
- When is CPI released?
- Mid-month, typically the second Tuesday or Wednesday, at 8:30 AM ET.
