Chair Warsh is presented with a critique of trimmed mean PCE measures ("on May 31st, 2026, the Wall Street Journal reported that you want the Federal Reserve to give greater weight to the Dallas Fed's trimmed mean PCE") in that it registered the 2021-22 inflation rise late and was understated vs core PCE. Warsh responds (including a subtle reference to the ex-WalMart CEO's inclusion on his data task force):
- "So none of those are very good measures of underlying inflation. That Wall Street Journal story that you referenced is incorrect, that I have a preferred measure from one of the reserve banks. If I had a preferred measure, I wouldn't have called for a task force to go back to first principles. And the data task force will be looking importantly at inflation measures. My view is that we need new measures to understand the underlying changes in inflation. Am I interested in what's the mean or median price of a good in a big box retailer? You bet I am, and none of these measures capture that. I am super interested in finding new measures to do a better job to help us inform our decisions so that the inflation of the last five years don't continue."
- Recall Warsh said in his April nomination hearing that "The measures I prefer are looking at things that are called trimmed averages, where we take out all of the tail risks, all of the one off items, and we ask ourselves whether the generalized change in prices is having second order effects on the economy. Again, they're not where they should be, but I think that the trend is quite favorable" - as such he appears to be referring in his testimony today to the specific regional Fed measures as opposed to the broad principle.
