Senate questions inflation metric changes

Highlights

On June 24, the BEA announced revisions to calculating the PCE price index, which could lower reported inflation for key service categories.
Senator Warren raised concerns to Commerce and BEA about inflation metric changes impacting Fed policy, citing lack of consultation with key experts.
Warren criticized Commerce's June switch from noise infusion to coarsening for federal statistics, warning of reduced data detail and regional policy insight.

Methodology changes draw congressional scrutiny

As reported by Senate Banking Committee, citing the Senate Committee on Banking, Housing, and Urban Affairs, Warren, the ranking member of the panel, has sent a letter to Under Secretary of Commerce Joyce Meyer and Bureau of Economic Analysis Director Vipin Arora seeking information on recent changes to inflation measurement and other statistical methods.

On June 24, the BEA announced a change to its methodology for calculating the Personal Consumption Expenditures price index, the Federal Reserve's preferred inflation gauge, for categories including portfolio management, legal services, and computer software and accessories. Economists estimate the revisions could lower reported inflation, a shift Warren says is significant as President Trump continues to pressure the Fed over monetary policy.

In the letter, Warren says changes to metrics used by the Fed to set interest rates and pursue its mandate of maximum employment and stable prices could carry meaningful consequences for American families and workers. She also raises concerns that some of the adjustments may have been made without consultation with key experts.

Concerns over data quality and policy impact

Warren also points to a separate June decision by Commerce to bar federal statistical agencies from using noise infusion, a longstanding privacy protection technique for local data, in favor of coarsening, which produces broader and less detailed estimates, or in some cases no data at all.

She argues that the switch could limit the ability of policymakers and market participants to understand the regions they serve, while again questioning whether outside specialists were consulted. Warren says the methodology changes come after what she describes as a series of Trump administration actions affecting the U.S. statistical system, including the firing of Bureau of Labor Statistics Commissioner Dr. Erika McEntarfer and the cancellation of a monthly jobs report during last year's government shutdown.

Warren has requested detailed responses from Meyer and Arora by Aug. 20, 2026, to clarify how the Commerce Department and the BEA reached their decisions.

The Senate Banking Committee’s hearing on expanding access to capital focused on reducing geographic and regulatory barriers that limit funding for entrepreneurs, growing companies, and everyday investors. Our earlier article highlighted proposals aimed at widening public-market participation, tailoring rules for firms at different growth stages, and improving investment options and costs for retirement savers—issues that shape how policy decisions ripple through markets and the real economy.
