Washington, United States – The U.S. Bureau of Economic Analysis (BEA) will implement a major overhaul of the Personal Consumption Expenditures (PCE) price index, the Federal Reserve’s preferred gauge of inflation, with changes scheduled to take effect on September 30, 2026. The new methodology will be applied retroactively to data back to 2021, effectively rewriting about five years of official core inflation history. The revisions will concentrate on three key components of the core PCE index: portfolio management and investment advice services, legal services, and computer software and accessories. To calculate prices for these categories, the BEA plans to rely more heavily on data from the Producer Price Index and various composite indices, replacing older approaches that used less representative inputs such as employment-based extrapolators. Washington, United States – The timing of the methodological shift is set to align with the BEA’s annual comprehensive revisions to U.S. gross domestic product data on September 30, allowing the government to update major national economic indicators in a single coordinated release. Economists and Wall Street analysts estimate that the updated methods will lower recent core PCE readings by roughly 0.2 percentage points, a change that appears modest to the public but represents a substantial adjustment for policymakers. The recalculated inflation path will feed directly into how central bankers interpret recent price trends and assess the trajectory of U.S. inflation, providing a new statistical basis for evaluating the effectiveness of past policy decisions and the stance of monetary policy going forward.
