CPI vs Core CPI — Year-over-Year Change
What is the Consumer Price Index (CPI)?
The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It is one of the most closely watched economic indicators and the most widely used measure of inflation.
Published monthly by the U.S. Bureau of Labor Statistics (BLS), the CPI measures price changes for items including food, housing, apparel, transportation, medical care, recreation, education, and communication.
Key Measures:
- Headline CPI (YoY): Year-over-year change — the broadest inflation gauge, includes food and energy
- Core CPI (YoY): Excludes food and energy — the Fed's preferred measure for underlying inflation trends
- CPI (MoM): Month-over-month change — indicates the current pace of price movement
- Core CPI (MoM): Month-over-month core change — closely watched for early trend signals
Why It Matters:
- The Federal Reserve monitors CPI alongside PCE to guide interest rate decisions
- Social Security benefits and tax brackets are adjusted based on CPI
- Financial markets react significantly to CPI surprises — especially Core CPI
- Businesses use CPI for wage negotiations and pricing decisions
