Senator Warren Probes Changes in US Inflation Metrics

US Senator Elizabeth Warren has sent a letter to Commerce Department officials and Bureau of Economic Analysis Director Vipin Arora, expressing concerns over recent changes to key US inflation metrics. These revisions could impact the way policymakers assess economic data and make interest-rate decisions.

The changes include a switch from noise infusion to coarsening for federal statistics, which Warren argues will reduce data detail and regional policy insight.

Warren also criticized Commerce's decision to bar the use of noise infusion in favor of coarsening, stating that this could limit policymakers' understanding of regional economic conditions.
