SkimNews Take
A trimmed-average inflation gauge, while designed to smooth out volatility, risks amplifying the impact of persistent, moderate price changes in previously excluded categories, potentially leading to more frequent policy adjustments.

- Kevin Warsh proposes trimmed‑average inflation measures, saying they remove “one‑off” geopolitical or supply shocks and show a 2.3% mean and 2.8% median for February versus a 3% core PCE.
- Aditya Bhave of Bank of America warns that trimming only extreme readings can let smaller food and energy spikes raise the trimmed mean, which in 2019‑20 made the gauge higher than core PCE and could push the Fed hawkish.
- Federal Reserve currently relies on the core PCE at 3%, but switching to Warsh’s trimmed‑mean could shift policy decisions, affecting interest‑rate outlooks and market expectations.
Why it matters: The Federal Reserve will justify rate cuts with a 2.3% trimmed‑mean inflation reading, while borrowers risk higher rates if the metric climbs above the 3% core PCE, potentially eroding Fed credibility and prompting market volatility.
