U.S. Senator Elizabeth Warren is seeking details on upcoming adjustments to the Federal Reserve's preferred measure of inflation, the Personal Consumption Expenditures (PCE) price index. The new methodology, set to be implemented with August data (released in September), could potentially lower reported inflation by approximately 0.2 percentage points. Warren called for greater transparency but did not mention evidence of political interference. The revisions will impact the pricing of software, legal services fees, and investment advisory, but will not affect the Consumer Price Index (CPI).
