The Bureau of Economic Analysis announced a methodological update to the Personal Consumption Expenditures (PCE) price index, the Federal Reserve’s preferred inflation measure, which is expected to reduce recent core inflation figures.
Starting September 30, 2026, the BEA will apply new price calculation methods retroactively to data from 2021, revising the inflation trajectory for the past five years. This change aligns with the BEA’s annual GDP data revisions.
Details of Methodology Update
The BEA will adjust pricing approaches for three categories: portfolio management and investment advice services, legal services, and computer software and accessories. The update replaces previous calculations based on less representative data with more full inputs drawn from the Producer Price Index and composite indices.
Impact on Inflation Figures and Market Outlook
Industry analysts Goldman Sachs and JPMorgan estimate that the May 2026 core PCE rate will be revised down to about 3.2-3.3% year-over-year, compared to the initially reported 3.4%. Although this represents a 0.1-0.2 percentage point decrease, it holds significance given the Federal Reserve’s long-standing 2% inflation target. Such a revision can influence the Fed’s perception of inflation persistence and potentially affect monetary policy decisions.
The revision also aims to harmonize PCE data with Consumer Price Index measures, broadening the inflation scope beyond direct consumer spending to include expenditures by employers and government programs.
Lower revised inflation readings may temper market expectations for continued restrictive interest rate policies by the Fed. However, experts caution that this change reflects a statistical adjustment rather than a shift in actual price levels.
