"Underlying" is the operative word. There's no single inflation rate. Headline CPI, core, core services ex-housing, supercore, trimmed mean. Each one tells a different story depending on what you want to see (Ang, 2014: inflation is not one thing). Shelter lags real-time rents by 12 to 18 months. Services ex-shelter runs on wages. Goods inflation is energy passthrough and tariffs. Saying tariffs aren't the cause while the goods line is still running hot is a convenient framing for a Fed seat candidate. Warsh is telling us which number he'll cite to justify the next cut. That's what matters here, not whether he's right.
