Energy Is Running the Inflation Print Again
Headline CPI at 3.4 percent is being dragged by an energy index up 16.3 percent. The Fed cuts into that anyway.

Key Highlights
- Headline CPI rose 3.4 percent for the 12 months ending August 2026, with the August monthly gain at 0.4 percent.
- The energy component is up 16.3 percent year over year; gasoline alone is up 27.4 percent.
- Core versus headline is no longer a minor decomposition: energy is contributing roughly a third of the headline print.
- A Fed easing cycle into rising energy costs has a specific historical failure mode: the 1970s stop-go cycle.
The surface story is disinflation stalled at 3.4 percent. The real catalyst is that the stall is not broad. One component, energy, is doing most of it, and the policy response being deployed against it is not the one that moves that component. That mismatch is the trade.[1]
The Bureau of Labor Statistics reported headline CPI up 3.4 percent for the 12 months ending August 2026, with a 0.4 percent monthly gain. The energy index rose 16.3 percent over the same window. Gasoline alone rose 27.4 percent, and fuel oil 52.0 percent.[1] Do the decomposition and the arithmetic is uncomfortable: with energy running a 16.3 percent year-over-year print against a 3.4 percent headline, energy is contributing on the order of a third of the total. The inflation problem of September 2026 is narrower than the headline suggests, and also more stubborn, because the narrow part is the part monetary policy touches least.
