Consumer Price Index (CPI): Release Dates, Results & History

Consumer Price Index (CPI) last printed 0.10% on Wed, Aug 12, 2026 against a 0.10% consensus forecast and a -0.40% prior, exactly on consensus. The next release is Friday, September 11, 2026 at 8:30 AM ET. Captured live by Helious the moment it printed.

CPI is the single most bond-market-moving release on the calendar. It sets the market's read on whether inflation is sticky or cooling, which feeds straight into Fed cut/hike pricing. Every desk trades the 8:30 print. The first tick after release is often the day's biggest move.

The trend, at a glance

OFFICIAL SERIES · LAST 35 OBSERVATIONS · % M/M
The official published series at its current vintage — revisions included, so the newest point can differ from the number as first printed. The release-by-release history with the consensus forecast and standard-deviation surprise on every row comes through the Helious API.

How it moves Treasuries

Hotter-than-expected CPI is bearish Treasuries: yields jump, led by the front end. A ±0.1% surprise vs consensus on the monthly print typically moves the 10-year around 4bps. See it scored live on the Helious desk, or read how the standard-deviation surprise is computed.
