The desk’s answer
PCE is the Personal Consumption Expenditures price index, released by the BEA roughly two weeks after CPI. It is the Federal Reserve’s preferred inflation measure and the series the 2 percent target is defined against. It runs lower than CPI on average because it weights shelter less, includes a broader basket, and accounts for substitution when prices change. Core PCE year-on-year is the single most important inflation number on the macro calendar because the FOMC’s rate path is set against it.
Defined term, PCE (Personal Consumption Expenditures price index)
PCE is the Personal Consumption Expenditures price index published by the Bureau of Economic Analysis, the Federal Reserve’s preferred measure of inflation. It is broader than CPI, weights shelter lower, captures spending substitution effects, and is the series the FOMC’s 2 percent inflation target is defined against, with core PCE the primary policy gauge.
Why PCE diverges from CPI
PCE typically runs 30 to 50 basis points below CPI on average. The largest reason is the shelter weight: CPI weights shelter at roughly 34 percent of core, PCE at roughly 17 percent. Because shelter has been running hot, the lower weight in PCE drags the headline lower. PCE also includes healthcare paid by employers and Medicare/Medicaid, which CPI excludes. And PCE uses chain-weighting that captures consumer substitution when prices rise, while CPI uses a slower-updating basket. The result is two valid inflation reads that often tell different stories at the margin.
Why the Fed targets PCE not CPI
The FOMC formally adopted PCE as the target measure in 2000 and 2 percent core PCE as the explicit goal in 2012. The reasoning was that PCE is broader, more representative of actual household spending, and less prone to the shelter weighting issue. CPI moves markets first because it is released first, but the policy decision is anchored on PCE. A trader who reads only CPI is reacting to the data the FOMC is not deciding on.
Trading the PCE release
PCE is released alongside Personal Income and Personal Spending in the BEA’s monthly Personal Income and Outlays report, typically on the last business day of the month at 13:30 UK time. The market focus is core PCE month-on-month and the trailing three-month annualised rate. Because CPI has been digested two weeks earlier, the PCE surprise is usually smaller and the reaction is more contained, but a divergence from CPI (CPI hot, PCE cool, or vice versa) is a high-conviction trade because it forces the rate path to reprice.
Frequently asked
What does PCE stand for?
Personal Consumption Expenditures price index, the inflation measure published by the Bureau of Economic Analysis. It is the Federal Reserve’s preferred gauge and the series the 2 percent inflation target is defined against.
Why does PCE run lower than CPI?
PCE weights shelter at roughly 17 percent of core, less than CPI’s 34 percent, and uses chain-weighting that captures consumer substitution. Both factors typically pull PCE 30 to 50 basis points below CPI on average.
When is PCE released?
PCE is released by the BEA monthly, typically on the last business day of the month at 13:30 UK time, in the Personal Income and Outlays report alongside Personal Income and Personal Spending.
