Gasoline Did the Damage, and Voters Noticed
The last inflation report before the midterms was not subtle.
The last inflation report before the midterms was not subtle. Consumer prices rose 3.7 percent over the year through September, up from 3.4 percent in August, and gasoline accounted for more than half of the monthly increase.
That is the kind of number a voter does not need a chart to understand. The pump is the chart.
The Bureau of Labor Statistics said the consumer price index rose 0.6 percent in September after a 0.4 percent increase in August. Core inflation, which excludes food and energy, rose 0.3 percent for the month and 2.6 percent over the year.
Those core numbers matter to economists. The gasoline number matters to people who drive to work.
What the report says
The details are mixed, which is often the case. Food prices were unchanged in September. Grocery prices fell 0.1 percent for the month and were up 1.8 percent from a year earlier.
That is real relief, but it is small relief. Food overall was still up 2.5 percent year over year.
Gasoline rose 9.1 percent in September. Energy prices rose 5.2 percent for the month.
A household can absorb a bad month in one category. It has a harder time absorbing a bad month at the pump, especially when the same trip includes a grocery store, a pharmacy, and a child care bill.
The political arithmetic
The election is on November 3. The report arrived less than a month before it. That timing gives both parties something to argue about, though neither party controls the receipt in a voter’s hand.
President Donald Trump has described the economy in favorable terms. The September data do not make that pitch easier. Inflation accelerated rather than cooled, and the increase came largely from an item voters buy often and remember clearly.
Polling cited in recent reporting suggests the cost of living is a central voter concern. An Emerson College Polling Center official told CBC News that the economy is the top issue, with cost of living, rather than jobs or taxes, underneath that concern.
An AP-NORC poll cited by The Philadelphia Inquirer found that 17 percent of U.S. adults approved of Trump’s handling of the cost-of-living issue.
I would not treat one poll as a verdict. But a 17 percent approval figure is not a strong defense of the status quo.
The old pattern
This has a familiar shape. In 2008, the political damage came when household budgets and financial headlines pointed in the same direction. In 2022, inflation did not need to be at a record to matter; it needed to be visible at the grocery store and the gas station.
The lesson was never that voters follow the consumer price index. They follow the gap between what they earn and what things cost.
That gap is harder to measure than inflation itself. Pay gains may look respectable in an average. Averages can hide a household whose rent, insurance, child care, and fuel costs rose faster than its paycheck.
Recent reporting said the September report further eroded Americans’ pay gains and compounded affordability concerns. That is the part campaigns should worry about. A voter does not experience “inflation.” A voter experiences the difference between last year’s budget and this year’s.
What is clear, and what is not
The documented facts are clear enough. CPI rose 3.7 percent year over year in September. It rose 0.6 percent for the month. Gasoline rose 9.1 percent and drove more than half of the monthly headline increase. Core CPI rose 2.6 percent year over year. Food prices were flat for the month, while groceries fell 0.1 percent.
What remains unknown is how long fuel costs stay elevated, how wages respond, and whether voters separate energy shocks from the broader economic record. The war with Iran has been identified in reporting as a driver of the fuel-price rebound.
That distinction may matter eventually. It may not matter on November 3.
Politicians often want voters to assign blame with the precision of an accountant. Voters tend to assign it with the precision of someone holding a receipt. If the receipt is worse than last year’s, the explanation has to be unusually good.
The market angle
For markets, the immediate question is whether this is a one-month energy spike or the start of a broader repricing. The core reading rose from 2.4 percent to 2.6 percent year over year, which is not a loud signal by itself. But it is not the direction policymakers or bond investors prefer.
The Federal Reserve has a 2 percent inflation objective. September’s headline rate was well above it.
That does not tell us what the Fed will do next. It does tell us that the “prices are settling down” story now has a hole in it.
For the campaigns, the practical issue is simpler. Voters are being asked to judge an economy while prices are still rising. The report does not settle the election. It does make the incumbent party’s argument harder, because the argument now has to explain why the number went up in the final weeks.
I have watched enough cycles to distrust any claim that one report decides anything. But I also distrust the idea that voters will ignore a 9.1 percent monthly jump in gasoline because the grocery aisle gave them a tenth of a percent back.
The money is doing the talking. The ballots will say whether anyone was listening.
