Core CPI (ex Food & Energy): release dates, results and history
Core CPI (ex Food & Energy) last printed 0.30% on Fri, Sep 11, 2026 against a 0.20% consensus forecast and a 0.20% prior, a +1.67 standard-deviation surprise. The next release is Wednesday, October 14, 2026 at 8:30 AM ET. Captured live by Helious the moment it printed.
Food and energy swing around more than anything else in the index, so core CPI throws both out and what is left reads the underlying trend more cleanly. The Fed and the rates desks watch the monthly core print more closely than the headline. A run of 0.3s instead of 0.2s, and the cuts that were priced in come back out.
The trend
How it moves Treasuries
On an inflation print a beat means hotter than consensus, and hotter is bearish for Treasuries. The move lands hardest in the belly, the middle of the curve, as the market reprices the Fed path. Miss to the downside and bonds rally fast, especially when cuts are live. See it scored live on the Helious desk, or read how the standard-deviation surprise is computed.
