US Fuel Prices Surge Ahead of 2026 Midterm Elections

Rising fuel costs are creating an economic and political challenge for President Donald Trump ahead of the 2026 US midterm elections, as gasoline and diesel prices climb following military conflict involving Iran. The national gasoline average reached $4.20 per gallon on Friday, while diesel climbed to $6.32, according to data cited by CNBC, putting additional pressure on American households, businesses, and agricultural producers.

The increases have complicated Trump's campaign promise to reduce gasoline prices below $2 per gallon during his first year in office. According to a Pew Research Center survey published October 30, 74% of Americans are very concerned about gasoline and energy costs, up from 60% in July and 43% in January.

Gasoline prices are nearly 40% higher than the same period last year, according to CNBC. Pew Research Center reported that regular gasoline averaged approximately $2.80 per gallon in late February before reaching a peak of $4.35 in mid-May. By October 26, the average remained at $4.12, representing a 47.4% increase from February.

Diesel has experienced an even sharper increase. Its price rose from $3.81 per gallon in late February to $6.35 on October 26, a 66.8% increase, according to Pew Research Center. The fuel is particularly important for trucking, transportation, and agricultural operations.

During his 2024 presidential campaign, Trump outlined his expectations for reducing energy costs at the New York Economic Club in September 2024.

"My plan will cut energy prices in half or more than that within 12 months of taking office," Trump said.

He also connected rising energy costs with broader economic difficulties facing American households.

"Energy was what caused our problem initially," Trump told voters.

Trump subsequently described lower fuel prices as central to his economic recovery plans.

"Energy is going to bring us back. That means we're going down and getting gasoline below $2 a gallon." Trump said.

However, the conflict involving Iran has disrupted international oil transportation. The United States and Israel launched a joint attack on Iran on February 28, prompting Tehran to retaliate against tankers traveling through the Strait of Hormuz. The disruption significantly reduced oil shipments through the strategic shipping corridor.

Patrick De Haan, head of petroleum analysis at GasBuddy, said the current price environment had exceeded earlier expectations for the year.

"Prices have never been this high this late in the year," De Haan said.

He had previously expected 2026 to deliver comparatively affordable gasoline prices.

"Trump got in his own way," De Haan said.

He explained that earlier projections had anticipated lower fuel costs without requiring additional government intervention.

"Back in December, we predicted that 2026 was going to be the cheapest year for gas since 2020. That required no effort. And obviously, it hasn't gone that way." De Haan said.

Trump defended the military operation despite its economic consequences, addressing rising fuel costs during a rally in Michigan the previous Sunday.

"Small price to pay," Trump said, referring to the cost of preventing Iran from obtaining a nuclear weapon.

White House spokeswoman Taylor Rogers maintained that fuel prices would decline after the military conflict ended.

"Once this conflict comes to an end, gas prices will drop drastically, and the Iranian terrorist regime will not have a nuclear weapon," Rogers said in a statement.

The White House also argued that inflation-adjusted gasoline prices had been higher around previous election periods. Meanwhile, attacks on Saudi Arabian refineries by Houthi rebels and Ukrainian strikes against Russian refineries have added pressure to international fuel supplies.

ExxonMobil CEO Darren Woods highlighted the economic importance of diesel after the company reported substantial profits amid market disruptions.

"Frankly, diesel is the key crunch point here because it is so critical to economic growth," Woods told CNBC on Friday.

Higher fuel expenses have also affected the airline industry, with carriers increasing ticket prices to compensate for rising jet fuel costs. Fuel remains their largest expense after labor.

Political pressure has intensified in Iowa, a traditionally Republican agricultural state where higher diesel costs are affecting farmers. Senator Chuck Grassley lobbied Trump to address the problem, while the state's Senate race became increasingly competitive.

Trump considered restricting diesel exports but abandoned the proposal because it could also increase gasoline prices. Instead, he authorized an executive order allowing truckers to use tax-exempt off-road diesel on US highways and announced an $8 billion assistance program for farmers facing higher fuel expenses.

He also reached an agreement with Russian President Vladimir Putin allowing Moscow to export approximately 6 million barrels of diesel into the global market through November. Ukrainian President Volodymyr Zelenskyy and several Republican senators criticized the arrangement, while energy analysts said the additional supply was too small to significantly influence global prices.

International oil markets have remained volatile ahead of the elections. Brent crude increased more than 13% in October, while US West Texas Intermediate crude gained 15% as investors considered the possibility of renewed military escalation after voting.

De Haan warned that further developments could affect fuel costs during the upcoming holiday travel period.

"If there are escalations, that could obviously put upward pressure on prices just ahead of Thanksgiving," De Haan said.

He also highlighted the seasonal increase in American road travel during the holiday.

"Which is also when Americans have really staunch traditions in terms of driving to friends and family." De Haan said.

Historical data provides additional context for the current increases. Pew Research Center found that June 2008 recorded the highest inflation-adjusted monthly gasoline price since the Energy Information Administration began collecting data in September 1990, reaching $6.18 per gallon in 2026 dollars. Diesel reached an inflation-adjusted $7.26 during the same month.

Pew Research Center also estimated that Americans needed approximately 9.5 minutes of work to earn enough to purchase one gallon of gasoline in October 2026, compared with 6.3 minutes in February. The calculation used an average gasoline price of approximately $4.14 and a national median hourly wage of $26.

For comparison, gasoline averaged $3.80 per gallon during the 2022 midterm elections, according to AAA data cited by CNBC.
