A diesel export ban is being examined by the Trump administration after U.S. President Donald Trump said September 22, 2026, that he supports stopping some or all diesel shipments abroad as fuel prices climb.
Treasury Secretary Scott Bessent said officials were assessing whether restrictions would be feasible given the country’s refining capacity and whether a full or partial ban would work. No order has been issued, and the administration has not announced a timetable for a decision. A report provided details on the proposal.

What Trump said about diesel exports
Trump raised the proposal while speaking to reporters in New York alongside Ukrainian President Volodymyr Zelensky during the United Nations General Assembly. Asked about calls for an export restriction, Trump said he had already urged his administration to consider keeping more diesel in the United States.
His comments marked a shift from earlier resistance within parts of the administration. The proposal has gained support from some Republican lawmakers and candidates who argue that keeping U.S.-refined fuel at home could reduce costs for farmers, truckers and other heavy-duty users.
Bessent’s comments indicated that the policy remains at the examination stage. Officials are considering whether the restriction would cover all diesel exports or only a portion of shipments, according to a report.
Why the administration is considering a ban
Diesel prices have risen sharply amid disruptions affecting major fuel-producing regions, including the Middle East and Russia. Diesel is widely used in freight transportation, agriculture, construction, mining and heating, making price increases especially important for household and business costs.
The U.S. Energy Information Administration says distillate fuel oil, which is chiefly diesel, is the country’s largest transportation-fuel export by volume. U.S. distillate exports averaged about 1.3 million barrels per day in 2025, with Mexico the largest destination at roughly 220,000 barrels per day, according to EIA data.
That export role means the United States is connected to international diesel markets even when domestic production is strong. The EIA also reported that U.S. diesel exports to Europe more than doubled year over year in January 2026, reaching about 396,000 barrels per day, according to its diesel export data.
Could a diesel export ban lower prices?
Supporters argue that restricting exports would increase the amount of fuel available to American buyers and could reduce domestic wholesale prices in the short term.
However, the effect would depend on how refiners respond. A sudden loss of export outlets could fill storage tanks, reduce refinery operating rates and discourage production. Because refineries produce diesel and gasoline together, a reduction in diesel output could also affect gasoline supplies.
Energy-market analysts have warned that a broad restriction could create a temporary domestic surplus while tightening supply elsewhere. That could lower U.S. prices initially but increase prices in other markets and eventually create new pressure on American refiners and consumers. Analysts have warned of these effects.
What it could mean for Canada
Canada is closely linked to the U.S. energy market through cross-border fuel trade, transportation networks and shared refining and distribution infrastructure. A U.S. restriction would not automatically create a Canadian diesel shortage, but it could disrupt regional supply patterns.
If U.S. exports were redirected or reduced, Canadian buyers could face higher costs for replacement supplies, especially in regions that rely on North American fuel flows. Trucking, agriculture and other diesel-intensive industries could then pass some of those costs through to freight, food and other consumer goods.
That possible impact is an inference from the scale of U.S. exports and the interconnected nature of North American fuel markets, not an announced Canadian government forecast. Canadian freight costs have already been sensitive to diesel-price movements.
How could Trump impose restrictions?
The administration has not identified the legal mechanism it would use. The Congressional Research Service has documented that the International Emergency Economic Powers Act authorities can give a president authority to regulate or prohibit exports connected to a declared national emergency, although the scope and legal application would depend on the specific order and circumstances.
Any action could face opposition from refiners, exporters, lawmakers representing energy-producing states and trading partners affected by reduced access to U.S. fuel. A broad restriction could also trigger legal challenges and commercial disputes.
What happens next
The immediate next step is an administration review of domestic refining capacity, inventory levels, export destinations and the likely effect of full or partial restrictions.
Until a formal executive order, regulation or other government action is announced, the proposal does not change diesel exports or fuel prices. The administration could ultimately pursue a temporary restriction, a limited country-specific measure, a partial quota or no ban at all.
For Canadian households and businesses, the key issue will be whether Washington moves beyond political discussion and how refiners, traders and other governments respond if restrictions are introduced.
Frequently Asked Questions
Has Donald Trump imposed a diesel export ban?
No. As of September 23, 2026, Trump has backed the idea, but no diesel export ban has been formally announced or implemented.
What is the Trump administration considering?
Officials are examining whether a full or partial restriction on U.S. diesel exports would be feasible given domestic refining capacity and market conditions.
Why would the United States consider restricting diesel exports?
Supporters say keeping more fuel in the domestic market could reduce costs for American farmers, truckers and other diesel users.
Could a diesel export ban raise prices?
Yes. A ban could lower prices temporarily in the United States but disrupt refinery production and increase prices in international markets.
Could Canada be affected by a U.S. diesel export ban?
Canada could face indirect effects through North American fuel trade, replacement-supply costs and higher expenses for trucking, agriculture and other diesel-dependent sectors.
