Inflation (CPI) 3.4%

Headline CPI, 12 months to August 2026 · Published 11 Sep 2026 · Next release 14 Oct 2026 (in 25 days)

Headline inflation held at 3.4% over twelve months while prices rose 0.4% on the month — the fastest monthly pace of the summer. Core eased to 2.4%.

The release, in the same format we use for every indicator
Previous (July 2026)+3.4% y/y · +0.1% m/m
Actual (August 2026)+3.4% y/y · +0.4% m/m
Core (ex food & energy)+2.4% y/y · +0.3% m/m — down from 2.5%
Why it mattersThe twelve-month figure did not move, but the monthly pace did: 0.4% is an annualised rate well above target. Core at 2.4% is the closest it has come to 2%. Five days later the Fed raised.

Inflation is 3.4%. Gasoline is up 24.6% over the same twelve months. That gap explains almost every argument about the economy right now.
