24.6%

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.

What happened
Gasoline prices rose 24.6% in the twelve months to July 2026, and total energy costs rose 14.7%, while overall consumer prices rose 3.4%.
Why
Energy is a small share of the CPI basket but an outsized share of what people notice — and it is the main reason headline inflation is running above core.

Why investors care
The gap between what the inflation rate says and what people experience is not a measurement error. It is a composition effect, and it has political and monetary consequences.

One number, explained properly. Today's is 24.6%.

That is how much the price of gasoline rose in the United States over the twelve months to July 2026, according to the Bureau of Labor Statistics. Over the same period, the overall consumer price index rose 3.4%.

Why one item can be up 25% while inflation is 3.4%

The consumer price index is a weighted average of thousands of prices. Each category is weighted by roughly how much of a typical household's spending it represents. Gasoline is a real cost, but it is a modest share of total spending — far smaller than shelter, which is up 3.2%, or food, up 3.0%.

So a very large move in a small-weight category produces a small move in the index. The arithmetic is correct. The experience is also correct. They are measuring different things: the index measures the average basket, and you buy your own basket.

Why it matters for interest rates

Central banks generally focus on core inflation — the measure that excludes food and energy — because energy prices are volatile and driven by supply, which interest rates cannot easily influence. Core is 2.5% and falling, close to the Fed's 2% objective.

But the Federal Reserve's mandate is written on the headline measure, and headline inflation is 3.4%. Three Fed officials dissented in July in favour of raising rates. This gap is what they are arguing about.

The one thing to take away

When a headline says "inflation is 3.4%," the useful follow-up question is never "is that high?" It is "which components?" A 3.4% figure driven by energy behaves differently from a 3.4% figure driven by shelter or wages — different persistence, different policy response, different consequences for what you own.

One number, taken alone, is almost always the wrong number.
