US Petrol Prices 2025 — Tariffs, Drill Policy, Refinery Capacity, and the Pump Price Paradox

The US produced more oil in 2024 than any country in history — yet American drivers paid an average USD 3.40/gallon for petrol in mid-2025, well above the pre-pandemic norm. The paradox has a structural explanation: production records don't lower pump prices the way politicians suggest.

Record production, volatile prices

US crude oil production averaged 13.2 million barrels per day in 2024 — a world record, surpassing the previous US record set in 2023 and well above Saudi Arabia's output. The shale revolution, concentrated in the Permian Basin, continues to deliver productivity gains: Permian wells drilled in 2024 produced on average 25 % more oil in their first year than equivalent wells drilled in 2019.

And yet, the average US retail price for regular petrol in 2025 has oscillated between USD 3.10 and USD 3.70/gallon, roughly in line with 2023–2024 averages. The EIA weekly retail petrol price data shows no structural downward trend attributable to the production surge.

The reason: US crude is sold on global markets. An additional Permian barrel competes against Norwegian, Saudi, and Iraqi supply on the global Brent crude benchmark — and its marginal downward price effect is diluted across 103 million barrels of daily global consumption. A 100,000 b/d incremental US production increase moves Brent by fractions of a dollar.

The tariff effect on refinery costs

The most direct domestic policy impact on 2025 US pump prices came from an unexpected direction: tariffs on Canadian crude oil. The US imports approximately 4 million barrels per day from Canada — primarily Alberta heavy oil sands crude — making Canada by far the largest foreign supplier. Midwest refineries in Illinois, Indiana, Michigan, and Ohio were specifically built and configured to process this heavy crude, and cannot easily substitute US shale (which is light and sweet).

When the administration imposed 10–25 % tariffs on Canadian energy imports in early 2025 (part of the broader Canada–Mexico tariff agenda), Midwest refinery feedstock costs rose sharply. Heavy crude from Canada had traded at a discount to WTI; with tariffs, that discount was partially offset, raising the effective cost per barrel for affected refineries.

West Coast (PADD 5)~30–50 cents/gal premiumLargely unaffected by Canadian crude tariffs
Northeast (PADD 1)~5–10 cents/gal premiumMinor impact

The tariff-refinery cost link is an example of how trade policy that sounds unrelated to fuel prices directly affects what consumers pay at the pump. The refinery gate price entry explains the cost stack, and what makes up the price at the pump covers the full decomposition.

Refinery capacity squeeze

During the COVID-19 pandemic, several US refineries permanently closed — approximately 1 million barrels per day of capacity was retired between 2020 and 2023. The closures reflected the economic logic of low pandemic-era demand, existing asset age, and uncertainty about long-term fossil fuel demand. But by 2024, demand had fully recovered while supply remained constrained.

No significant new US refinery capacity has been built since the late 1970s. The last greenfield US refinery was Marathon's Garyville expansion in Louisiana (1976). Environmental permitting, high capital costs, and uncertain long-term demand make new refinery investment in the US effectively impossible. This structural constraint means that US refinery utilisation routinely exceeds 90 %, leaving little buffer for planned or unplanned outages.

When a major refinery shuts for maintenance or has an incident — as occurred at several US Gulf Coast refineries in 2025 — the crack spread widens immediately, translating to higher pump prices within days. The crack spread glossary entry explains this mechanism.

Regional price variation

US petrol prices vary significantly by state — more than in most other large economies — due to different state excise taxes, local refinery access, and pipeline infrastructure. California consistently pays 70–90 cents/gallon more than the US average, due to its unique fuel blend requirement (CARB-spec fuel), high state taxes (68 cents/gallon combined excise + sales), and isolated refinery market with limited pipeline connectivity to the Gulf Coast.

The federal excise tax on petrol is 18.4 cents/gallon — unchanged since 1993 and not inflation-adjusted, making it one of the most eroded fuel tax rates among developed economies. Unlike European excise duty systems, the US federal rate represents less than 6 % of the pump price, providing minimal dampening of crude price volatility.

Outlook for US pump prices

The EIA's mid-2025 forecast put regular petrol averaging USD 3.20–3.50/gallon through the remainder of the year — below the 2022 peak of USD 5.00 but above the pre-2021 norm of ~USD 2.50. Key risks: further tariff escalation on Canadian crude, a hurricane disrupting Gulf Coast refinery operations, or renewed OPEC+ production cuts tightening Brent above USD 85/barrel.

The deregulatory agenda may slightly reduce long-run production costs and improve pipeline infrastructure, but is unlikely to structurally move pump prices below global parity. The OPEC and fuel prices guide explains why domestic production records don't translate to domestic price discounts in a globally integrated oil market.

Frequently asked questions

Why are US petrol prices still high despite record oil production?

US crude is exported globally, so pump prices track Brent benchmarks. Additionally, tariffs on Canadian crude raised Midwest refinery costs, refinery capacity has declined since COVID closures, and the production record's marginal price effect is diluted across 103 mb/d of global consumption.

How do tariffs on Canadian oil affect US petrol prices?

Midwest refineries are configured for Canadian heavy crude and can't easily switch feedstocks. The 10–25 % tariffs raised feedstock costs, widening the Midwest petrol price premium over Gulf Coast prices from ~5 cents/gal to ~12–18 cents/gal.

What is the "drill, baby, drill" policy and has it worked?

The Trump deregulatory energy agenda covering accelerated federal land leasing and streamlined permitting. US production was already at records when it launched. Industry responded with capital discipline rather than a drilling surge, as investors prioritised returns over growth.

Does US crude oil production directly lower US petrol prices?

Only indirectly, through the global market. Since US crude is freely exported, its marginal price effect is spread across 103 mb/d of global consumption. Domestic pump prices would only decouple from global markets through export restrictions or a major refinery surplus — neither of which exists.
