Consumer Price Index (CPI): release dates, results and history
Consumer Price Index (CPI) last printed 0.40% on Fri, Sep 11, 2026 against a 0.40% consensus forecast and a 0.10% prior, exactly on consensus. The next release is Wednesday, October 14, 2026 at 8:30 AM ET. Captured live by Helious the moment it printed.
Every desk trades the 8:30 print. CPI is where the market makes up its mind about whether inflation is sticky or cooling, and that call is what drives the pricing for Fed cuts and hikes. Nothing else on the calendar moves the bond market as much, and the first tick after the number lands is often the biggest move of the day.
The trend
How it moves Treasuries
A hot CPI is bearish for Treasuries. Prices fall, yields jump, and the short maturities at the front of the curve lead the move. Miss consensus by 0.1% in either direction on the monthly print and the 10-year typically moves about 4bps.
