What is PCE?
The Personal Consumption Expenditures (PCE) price index is the Federal Reserve's preferred measure of inflation. It tracks changes in the prices of goods and services purchased by consumers, providing a comprehensive view of inflationary pressures in the economy.
PCE vs CPI
Key differences from CPI:
- Scope: PCE covers all personal consumption, CPI focuses on urban consumers
- Methodology: PCE uses expenditure data, CPI uses fixed basket
- Weights: PCE weights update annually, CPI updates periodically
- Components: PCE includes more comprehensive spending categories
Why the Fed Prefers PCE
- Broader Coverage: Includes all consumer spending, not just urban
- Real-time Updates: Weights adjust with spending patterns
- Quality Adjustments: Better accounts for product improvements
- Comprehensive Data: Ties directly to GDP calculations
PCE Components
| Component | Weight | Description |
|---|---|---|
| Goods | ~25% | Durable and non-durable goods |
| Services | ~60% | Housing, healthcare, financial services |
| Energy | ~4% | Gasoline, fuel oil, electricity |
| Food | ~11% | Food and beverages purchased for off-premises consumption |
Core PCE
The Fed's primary focus:
- Definition: PCE excluding food and energy prices
- Why Important: Food and energy prices are volatile and temporary
- Fed Target: 2% annual increase in core PCE
- Policy Guide: Primary indicator for rate decisions
Fed's Dual Mandate
The Federal Reserve has a dual mandate: maximum employment and price stability (2% PCE inflation). PCE is the primary measure for assessing progress toward the price stability goal.

- 1970s: High inflation period, PCE averaged 7.5%
- 1980s: Volcker disinflation, PCE dropped to 3.5%
- 1990s-2000s: Low inflation era, PCE averaged 2.2%
- 2021: Post-COVID surge to 6.3%
- 2022: Peak at 6.3%, then decline
- 2023: Core PCE at 2.7%, approaching target
