Gas at $4.20, Diesel Up 71%: Fuel Prices Hit Election-Eve Highs

U.S. fuel prices are at their highest ever for an election day, two days before the November 3 midterms. Regular gasoline averaged $4.20 a gallon on Friday, nearly 40% above a year earlier, diesel reached $6.32 a gallon, up about 71% in a year, and jet fuel has risen even faster — a squeeze that has become a central campaign issue.

What happened, in one answer

AAA put regular gasoline at $4.2046 a gallon on October 30, up 38.4% from $3.0377 a year earlier, and diesel at $6.3204, up 71.3% from $3.6889. The Energy Information Administration's weekly survey told the same story, with gasoline at $4.269 and diesel at $6.352 in the week of October 26. GasBuddy's head of petroleum analysis, Patrick De Haan, said gasoline and diesel are forecast to be the highest ever on an election day, adding: "Prices have never been this high this late in the year."

Jet fuel rose fastest of all

The sharpest move is in the fuel airlines burn. The Gulf Coast spot price for kerosene-type jet fuel was $4.444 a gallon on October 27, up 97.5% from $2.250 on the same date in 2025. Jet fuel is airlines' largest expense after labour, and U.S. airfares rose 5% in September as carriers passed the cost on, according to reporting cited by QNC News. For drivers, the comparison with the last midterms is stark: during the 2022 midterms, in the year Russia's invasion of Ukraine triggered an energy crisis, retail gasoline stood at $3.80 a gallon, according to AAA data cited by CNBC — well below today's $4.20.

Why it's blowing up now

Timing is everything. Voters head to the polls on Tuesday, November 3, to decide all 435 House seats and about a third of the Senate, and fuel is one of the most visible prices in daily life. President Donald Trump promised in September 2024 to cut energy prices in half within 12 months and bring gasoline below $2 a gallon. Instead, prices spiked after the February 28 joint U.S.-Israel attack on Iran, when Tehran retaliated against tankers transiting the Strait of Hormuz and oil flows through the vital route fell sharply. Brent crude settled at $115.32 a barrel on October 28, up 13.6% in October, while U.S. West Texas Intermediate settled at $102.78, up 15.2% — and markets are pricing in the risk of renewed fighting after voting ends.

Diesel is the real crunch point

Gasoline gets the headlines, but diesel moves the economy: it powers trucks, farm machinery and freight. ExxonMobil chief executive Darren Woods told CNBC on Friday that "diesel is the key crunch point here because it is so critical to economic growth." Record diesel prices arrived in September even as crude softened at times — an early sign, analysts say, that refining constraints, not just the cost of crude, are driving the squeeze at the pump. CNBC reported Americans have paid about $59 billion more for fuel since the Iran war began, roughly $450 per household; Brown University estimates $146.1 billion more on gasoline and diesel alone. The methods differ, so treat them as a range.

What Washington has done so far

Under pressure from farm states, the administration allowed truckers to use tax-exempt off-road diesel on highways and announced an $8 billion farmer relief program. A diesel export ban was dropped over fears it would raise gasoline prices. A deal for Russia to export about 6 million barrels of diesel through November drew criticism; analysts say the volume is small versus global demand. The White House said that, adjusted for inflation, prices have been higher around previous election days, and that prices will fall drastically once the conflict ends.

What's next

Watch three things this week: the midterm results on Tuesday, crude prices if Middle East tensions escalate after the vote, and the run-up to Thanksgiving travel, when De Haan warned further escalation could push prices higher just as Americans drive to see family. Whether fuel relief arrives will depend less on campaign promises than on Hormuz shipping, refinery capacity and whether crude's October rally — Brent up more than 13%, WTI up 15% — continues into winter.
