US inflation rises to 3.7% before midterms, leaving Fed rate decision uncertain

US inflation rose to 3.7% in the year to September, according to Consumer Price Index figures released on Wednesday, October 14, 2026. The increase from August’s 3.4% puts renewed attention on the Federal Reserve’s next rate decision, due at its October 27–28 meeting, as Americans prepare to vote in the November 3 midterm elections.

Consumer prices rose 0.6% between August and September, compared with a 0.4% monthly increase in August. The Associated Press described September’s rise as the largest in five months. The annual and monthly readings tell different parts of the same story: prices were higher than a year earlier, and their increase accelerated in the latest month.

Gasoline and shelter costs in September’s inflation report

Gasoline prices jumped 9.1% in September. Al Jazeera reported that gasoline accounted for more than half of the monthly increase in the overall index, making it a substantial part of the latest rise. That contribution matters when interpreting the headline figure: the sharp move in fuel prices had a pronounced effect on the monthly reading.

Other measures also rose. The Associated Press reported that core consumer prices, which exclude food and energy, increased 0.3% from August and 2.6% over the year to September. The annual core rate was 2.4% in August. Al Jazeera reported that shelter costs rose 0.4% over the month, after a 0.3% increase in August. Those figures show that the release contained increases beyond gasoline, although the reported component figures alone do not establish the contribution of every category to overall inflation.

Why the Federal Reserve’s October decision remains uncertain

Al Jazeera reported that economists were divided over whether the Fed would raise rates again or hold them steady. The AP reported that most Wall Street investors expected a hold at the October 27–28 meeting, while some anticipated a possible increase in December. These accounts describe expectations ahead of the meeting; the Fed has not made its October decision.

One measure cited by Al Jazeera showed how closely balanced the immediate possibilities appeared. Its reported CME FedWatch estimates assigned a 52.9% chance to rates remaining at 3.75% to 4.00% and a 47.1% chance to a quarter-point increase. Those market-implied probabilities are a snapshot of expectations, and they help explain why the inflation release has drawn attention without settling the policy question.

Inflation and the November 3 midterm elections

The AP reported that September’s figures were the last major inflation data scheduled for release before the November 3 midterm elections. That timing puts the price report into an election campaign in which views of the cost of living and the economy are already being measured. The figures establish the change in consumer prices; they do not, by themselves, establish how voters will respond.

An AP-NORC poll cited by the AP found that 17% of US adults approved of President Donald Trump’s handling of the cost of living, while 26% approved of his handling of the economy. These are measures of public opinion, separate from the government’s price index. Together with the election timetable, they explain the political attention to the release without turning the inflation data into a prediction of the vote.

Financial markets were lower after the release, according to Al Jazeera’s account of midday trading: the Nasdaq was down 0.8%, the S&P 500 was down 0.6%, and the Dow was roughly flat. That was a reported market snapshot, while the next scheduled policy decision remains the Fed’s October 27–28 meeting. The inflation figures give officials new data to weigh at that meeting, but the accounts report no decision from it yet.
