Trimmed Mean PCE

Trimmed-mean PCE is Core PCE's quieter cousin: same Fed target, same monthly release, but instead of excluding food and energy by rule, the Dallas Fed throws out whichever categories swung most extremely that month — lower 24% and upper 31% of price changes by weight. The leftover middle is the underlying trend, with one-time category shocks (a hurricane's gasoline spike, a single airline-fare reset, an avian-flu egg move) already stripped out. Newly-confirmed Fed chair Kevin Warsh has flagged this as one of his two preferred gauges of underlying inflation, so it's worth watching independently of Core PCE for what the sitting chair is actually steering by. How to read it against Core PCE on the same page: when trimmed-mean reads notably softer than core, the gap is telling you the core print is being lifted by a small set of outsized category moves the policy lens probably shouldn't lean on — i.e. inflation is closer to target than core suggests, and the Fed has more room to cut than the core print implies. When they read in lockstep, the inflation story is broad-based and core is doing its job. When trimmed-mean is hotter than core, the underlying trend is firmer than headline readings suggest — that's the configuration where any nascent disinflation in core is fragile. Rated against the same 2% target and 1pp tolerance as Core PCE so the two cards are directly visually comparable.
