US consumer prices rose 3.7% in September as fuel costs bit harder

US consumer prices rose 3.7% in the year to September, the Labor Department said on Wednesday³. The index rose 0.6% on the month, against a 0.4% monthly increase in August, when the annual rate was 3.4%³. Core prices, which exclude volatile food and energy costs, gained 0.3% on the month³. The BBC reported that the pace of price rises increased by more than expected and was driven by higher motor fuel costs².

The Wall Street Journal described the reading as a sign that high energy prices are tightening their squeeze on consumers ahead of next month’s midterm elections¹. PBS News said inflation worsened last month and remains above the Federal Reserve’s 2% target⁴. Axios attributed the figures to the Bureau of Labor Statistics and said soaring energy prices had added to already stubborn price pressures³.

Why it matters to investors

Axios said the release shows the inflation fight is far from over and makes further Federal Reserve interest rate increases more likely³. Gold fell more than 1% after the data as traders raised bets on a Fed increase this month, Reuters reported⁶.

Before the release, prediction markets put the chance of a reading above 3.6% at 55%, and Interactive Brokers’ commentary said the print was expected to be the first acceleration since May, with heavier fuel costs lifting the rate⁷. MarketWatch reported that Cleveland Fed President Beth Hammack said in a speech that the rise in energy prices is not the whole story and that there are cost pressures from many sectors⁸.

The political setting runs through every account. The BBC headlined the rise as coming ahead of the midterm elections², PBS News framed it as inflation worsening as those elections near⁴, and Axios tied the report to the administration’s record on prices³. The mechanical question for investors is narrower: whether a 3.7% annual rate with a 0.6% monthly print is consistent with the Fed holding, which is what Hammack’s remarks addressed^3,8.

What to watch

The report followed surveys showing a deterioration in consumer sentiment, which had been expected to frame it⁵. MarketWatch cast the September figure as potentially decisive for whether the Fed raises interest rates⁸.

Reuters also carried the view that over a longer horizon gold should again benefit from continued strong central bank buying, even after the day’s fall⁶. None of the reports in this pack says a policy decision has been taken; they describe expectations only^3,8.

Ahead of the release, forecasters had expected high gasoline prices to lift the September reading, and the figure then came in above expectations^2,5.
