Will any FOMC voting member publicly call for changing the primary inflation data source used in policy communication?

The current FOMC, under Chair Kevin Warsh, has maintained a restrictive stance, reflected in the unchanged federal funds target range of 3.50 to 3.75 percent and a higher year end 2026 funds rate projection of 3.8 percent in the June 2026 SEP. This suggests a focus on inflation control, potentially making a shift in primary data sources less likely unless current data proves persistently misleading. However, the significant upward revision in the SEP median funds rate projection and the divergence among participants (nine of eighteen projecting rates above the current range) hints at potential underlying data interpretation challenges or differing views on the inflation outlook, which could eventually lead to calls for source examination.
