The headline 12-month and 1-month change in consumer prices for February 2027. The seasonally adjusted MoM rate is the cleanest month-to-month signal; the NSA 12-month rate is the headline figure quoted in media.
The Fed's primary CPI benchmark. February is a critical month for core because January seasonal factors (the "January effect" — large price resets in many services) can distort January data; February shows whether those January moves persist.
The most closely watched component in 2026–27. Markets want to see evidence that the new-lease rent disinflation (Zillow index near 0% since mid-2023) is finally flowing through to the CPI shelter component at the expected pace.
The Fed's preferred underlying inflation gauge, tracking the services component most closely linked to domestic wage growth. A reading below 4.0% annualised would be meaningfully dovish for March FOMC pricing.
How to read it
January CPI is notoriously difficult to interpret because many businesses reset prices at the start of the year — financial services, medical care, and some food categories often show large January adjustments. These "January effects" create a seasonal pattern that the BLS adjusts for, but the adjustment is imperfect. February CPI is a cleaner read: if the January jump in a category was genuine new inflation, it will persist into February. If it was seasonal noise, it will partly reverse. Professional forecasters compare the February seasonally-adjusted rate to see how much of January's surprise carries through.
Seasonal adjustment →By February 2027, shelter CPI should be considerably below the 4.9% reading of September 2026 — private rent indexes suggest the disinflation pipeline is robust. If shelter CPI has not fallen materially to the 3.5–4.0% range by February 2027, it would suggest the lag is extending further than expected and would push back the timeline for core CPI to sustainably approach 2%.

Core inflation →The February CPI release on 11 March is the last major inflation data point before the March FOMC meeting (typically mid-to-late March). This makes it unusually market-sensitive. If February core CPI surprises significantly higher (above 0.4% MoM SA), it could single-handedly shift market pricing from a cut to a hold at the March meeting. If it surprises to the downside (below 0.2% MoM SA), it would lock in a cut. The BLS also releases the February PPI two days later — together these are the two pre-meeting data points that matter most.
