Economists' consensus forecasts for the September 2026 Core CPI year-over-year rate cluster around 2.4%, reflecting a modest 0.2% month-over-month gain that would hold the annual pace steady from August's 2.4% print. Moderation in supercore services and core services ex-shelter is expected to offset firmer shelter components and vehicle prices, though upside risks from tariffs, discretionary services, and potential energy spillovers into goods keep 2.5% a close second in trader pricing. With the report due October 14, market-implied odds capture uncertainty over whether the data will confirm the anticipated cooling or register a slight reacceleration amid persistent core services pressures above 3%.
