What is the Personal Consumption Expenditures index?

The Personal Consumption Expenditures (PCE) price index is a measure of consumer inflation published by the Bureau of Economic Analysis (BEA) as part of the monthly Personal Income and Outlays report. The Federal Reserve officially targets 2% annual inflation as measured by the PCE index, making it the single most important inflation indicator for monetary policy decisions.

PCE is derived from the National Income and Product Accounts (NIPA) rather than from direct price surveys like CPI. The BEA constructs PCE using data from business surveys, Census data, CPI micro-data, PPI components, and administrative records. This methodology captures a broader scope of spending than CPI, including healthcare paid by employers and the government, financial services measured by fees embedded in spreads, and nonprofit services. The result is a more comprehensive view of the prices consumers effectively face.

The core PCE index, which excludes volatile food and energy components, receives particular attention from the Fed. Monthly core PCE readings are scrutinized to the hundredths of a percentage point because they form the basis for the Fed's inflation outlook in the Summary of Economic Projections (SEP). A core PCE reading of 0.2% month-over-month (annualizing to roughly 2.4%) is generally considered consistent with the Fed's target, while sustained readings above 0.3% suggest inflation is running too hot.

The timing of the PCE release matters for markets. PCE data come out roughly one week after the corresponding CPI release. Since many PCE components can be estimated from already-published CPI data, much of the information is already priced in by the time PCE is released. However, the healthcare and financial services components of PCE are independently derived and can surprise. Months where PCE deviates meaningfully from CPI-implied estimates produce significant market reactions, particularly for rate-sensitive assets like Treasuries and the US dollar.
