Why are gas prices rising in 2026?
U.S. gas climbed from $2.81 in January to $4.48 by May 2026. Here is what the price data shows — and what reputable reporting says is driving the jump.
Gas climbed 59% in five months
This part isn’t in dispute — it’s the EIA’s monthly national average for regular gasoline. The U.S. average started 2026 unusually low at $2.81 in January — below where it sat in 2024 and 2025 — then climbed to $4.48 by May, about 42% higher than the same month a year earlier. That pace pushed the pump price toward the 2022 peak of $4.93 (June 2022).

High — but not a record, once you adjust for inflation
Adjusted for inflation, May’s $4.48 is about $4.32 in constant 2025 dollars. That is genuinely steep — but it still sits below the inflation-adjusted highs of 2 earlier years (1981, 1980). The all-time record remains 1981 at $4.66 a gallon in today’s money. As of the week of June 15, 2026, the national average had eased slightly to $4.05.
What’s actually driving the 2026 jump
Crude oil is the main lever. Crude is the single biggest component of the pump price — about 57% of what you pay for a gallon of regular in March 2026, with refining (21%), taxes (14%) and distribution (8%) making up the rest. [3] So when crude moves sharply, gasoline follows.
And crude moved a lot. According to the EIA, Brent crude — after “beginning the year at $61 per barrel” — “finished the quarter at $118/b,” an increase the agency calls “the largest on an inflation-adjusted basis in data going back to 1988.” Brent topped $100 a barrel on March 12 and kept climbing into the end of March. [1] The agency’s June outlook puts the 2026 average near $95 a barrel, the highest since 2022. [2]
The trigger was a supply shock. U.S. and Israeli forces launched strikes on Iran beginning February 28, 2026; Iran responded by disrupting the Strait of Hormuz — the waterway through which roughly a fifth of the world’s traded oil passes — halting the vast majority of crude exports from the Persian Gulf. [5] The EIA attributes the price spike to that military action and the de facto closure of the Strait, which led producers including Iraq, Saudi Arabia and the UAE to shut in output. [1]
Being a big producer doesn’t shield U.S. drivers. The U.S. is the world’s largest oil producer, so why are Americans exposed? Because oil is priced on a global market. Energy analyst Clark Williams-Derry of the Institute for Energy Economics and Financial Analysis told PolitiFact that net-exporter status has “essentially no impact on the prices Americans pay at the pump”; the country also remains a net importer of crude, which many U.S. refineries are built to process. [4]
Refining margins added to it. The EIA notes refinery margins jumped as well — distillate crack spreads at New York Harbor reached their highest monthly level since 2022 — which feeds through to pump and diesel prices on top of the crude move. [1]
Seasonality is a minor factor here. Prices usually drift up heading into the summer driving season, but that seasonal pattern is small next to a crude shock of this size — the EIA’s analysis centers on the supply disruption, not the calendar. [1]
Where prices go next is unusually uncertain
The EIA’s June 2026 outlook forecasts retail gasoline averaging about $3.90 a gallon for 2026 — nearly a dollar above its February forecast — and easing toward $3.64 in 2027. [2] But the agency is explicit that the path hinges on when oil flows resume through the Strait of Hormuz; a forecast built on an active supply disruption carries more uncertainty than usual. We’re not predicting a number here — we’ll update this piece as the data and the reporting evolve.
2026 gas prices, answered
- Why are gas prices rising in 2026?
- The U.S. Energy Information Administration attributes the 2026 rise primarily to a sharp increase in crude oil prices, which make up about 57% of the retail price of gasoline. Crude jumped after U.S. and Israeli strikes on Iran beginning February 28, 2026 and Iran's disruption of the Strait of Hormuz — a chokepoint for roughly a fifth of the world's traded oil — halted most Persian Gulf crude exports. Higher refinery margins added to the move.
- How much have gas prices gone up in 2026?
- The U.S. average price of regular gasoline rose from about $2.81 per gallon in January 2026 to $4.48 in May — a rise of roughly 59% in five months, and about 42% higher than the same month a year earlier, per EIA monthly data.
- Are 2026 gas prices the highest ever?
- Not adjusted for inflation. May 2026's $4.48 works out to about $4.32 in constant 2025 dollars — high, but below the inflation-adjusted annual record of $4.66 set in 1981.
- Will gas prices come back down in 2026?
- The EIA's June 2026 outlook forecasts retail gasoline averaging about $3.90 per gallon for 2026, easing toward $3.64 in 2027, but stresses the path depends heavily on when oil flows resume through the Strait of Hormuz. Until then the outlook is unusually uncertain.
