US CPI: core calmer than headline

US CPI for 2026 M03 is out at the BLS bls.gov, and FRED’s CPILFESL series shows 0.1958 under pch on 2026-03-01, with pc1 at 2.60217 fred.stlouisfed.org. Against that, FRED’s headline CPIAUCSL series shows 0.86514 under pch and 3.28596 under pc1 on the same 2026-03-01 date fred.stlouisfed.org. That is the whole trading split: a much cooler core than headline. That is why core still does the real policy work. The hit-or-miss frame is whether desks treat the top line as noise that can be absorbed while the core path stays contained, or as the start of a broader re-acceleration that would matter for policy timing. These FRED values look more like series math than rounded BLS release percentages, so the extra decimal places are less important than the gap between the two gauges. A future core print softer than rates have priced could reopen the cuts trade; another upside core surprise could keep the longer-hold story alive.

US CPI for 2026 M03 is out at the BLS (news release: bls.gov table: bls.gov), and FRED’s CPILFESL series shows 0.1958 under pch on 2026-03-01, with pc1 at 2.60217 fred.stlouisfed.org. Headline is visibly hotter: FRED’s CPIAUCSL series shows 0.86514 under pch and 3.28596 under pc1 on the same 2026-03-01 date fred.stlouisfed.org. For traders, that keeps the read straightforward. If the core gauge is the better policy signal, this is not the same thing as a clean inflation re-acceleration across the basket, even if the top line is loud. The hit-or-miss frame is composition: a market that can live with a hot headline usually cannot ignore a core line that breaks higher, because that feeds more directly into the path for rates. These figures also read like calculated FRED change measures rather than rounded BLS percentages, so the signal is in the direction and the gap, not the extra decimals. In our view, the market is likely to trade the details more than the headline alone, and a future print outside what rates have priced could decide whether desks keep fading headline heat or start marking up a longer hold.
