WASHINGTON, October 14 — US inflation accelerated in September as gasoline prices surged and broader price pressures intensified, creating fresh economic and political challenges for President Donald Trump ahead of the November 3 midterm elections. The latest figures have also raised the possibility of an interest rate increase by the Federal Reserve later this month.

The Consumer Price Index (CPI), released Wednesday by the Labor Department, increased 0.6% in September, following a 0.4% rise in August. Annual inflation climbed to 3.7%, up from 3.4% the previous month, raising concerns that inflation may remain elevated beyond energy costs.

Financial markets have begun reassessing the Federal Reserve’s October 27–28 policy meeting, with the prospect of an interest rate increase becoming a closer consideration following the latest report.

Rising Energy Costs Drive Inflation

Gasoline prices jumped 9.1% in September, accounting for more than half of the monthly increase in consumer prices. Other motor fuels, including diesel, rose 11.9% during the month and were up 60.9% compared with a year earlier.

The ongoing US-Israeli war with Iran has contributed to higher energy prices, raising concerns that transportation and distribution costs could eventually push grocery prices higher.

Food prices remained unchanged in September after modest increases in July and August. Grocery store prices declined 0.1%, supported by lower beef, dairy and egg prices. However, nonalcoholic beverage prices increased 0.9%, while fruit and vegetable prices rose 0.5%. Banana prices increased 1.0%, and lettuce prices rebounded 3.9% as a cyclospora outbreak eased.

Despite the monthly decline, grocery prices remained 1.8% higher than a year earlier.

Consumers Face Growing Financial Pressure

The inflation report comes amid weakening consumer sentiment and declining public approval of Trump, with rising living costs becoming a major concern for American households.

A Reuters/Ipsos poll found that approximately 78% of Americans blamed Trump’s policies, including tariffs and the Middle East conflict, for rising prices that have outpaced wages.

Average hourly earnings for all employees fell 0.7% year over year in September, following a 0.3% decline in August. The figures underscore mounting pressure on lower-income households, which have less financial flexibility to absorb higher fuel, food and other living expenses.

Economists have questioned whether consumers can sustain their recent spending levels as purchasing power deteriorates.

AI Investment Adds to Inflation Concerns

Beyond energy costs, economists have raised concerns about emerging price pressures associated with artificial intelligence and the rapid expansion of data centers.

Kyle Moore, chief economist at the Century Foundation, attributed current inflation partly to government policy uncertainty, disruptions to global supply chains and the pace of AI infrastructure development.

The broader increase in prices has added to uncertainty over the economic outlook and the Federal Reserve’s next policy decision.

Social Security Benefits to Increase in 2027

Amid persistent cost-of-living pressures, the Social Security Administration announced a 3.6% cost-of-living adjustment for Social Security and Supplemental Security Income benefits in 2027.

The adjustment will affect nearly 72 million Americans, including retirees, people with disabilities, and eligible widows, widowers and children. Retirement benefits are expected to rise by an average of $75 per month.

However, higher benefit payments may offer only partial relief if essential expenses continue to increase.

Financial Markets React to Inflation Data

US financial markets responded negatively to the report. Wall Street stocks declined, the US dollar strengthened against a basket of currencies, and Treasury yields moved higher as investors reassessed the inflation outlook and the possibility of tighter monetary policy.

The latest figures leave the Federal Reserve facing a difficult decision: whether additional action is necessary to contain inflation or whether higher borrowing costs could place further pressure on consumers and economic growth.

With energy prices elevated, wages losing ground and the midterm elections approaching, the September inflation report has renewed concerns about the affordability of everyday life in the United States.
