President Donald Trump said on September 27 that he is still seriously considering a U.S. diesel export ban as high fuel prices put pressure on farmers and other diesel users. The administration has discussed full and partial restrictions, but no ban has been announced. U.S. diesel exports reached a record 1.6 million barrels per day in August, with Latin America and Europe among the principal destinations.
The proposal comes as U.S. refiners help replace diesel supplies lost from the Middle East and Russia. Europe’s share of U.S. diesel and gasoil exports rose to almost 50% in September, compared with a 30% average in 2025, according to Wood Mackenzie. A ban could therefore tighten overseas supply quickly, even if it initially leaves more diesel in the United States.
The operational risk is refinery capacity. Wood Mackenzie estimates that a full ban could redirect 700,000 barrels per day into U.S. storage and fill Gulf Coast diesel storage in just over a month. Refiners would then need to reduce the amount of crude they process by more than 2 million barrels per day, the firm estimates. That would also reduce gasoline output and could raise gasoline prices. These figures describe a modeled full ban, not an enacted policy.
Industry Impact
U.S. crude and refining capacity underpin the country’s role as a reliable “Safe Barrel” supplier. An export ban could weaken that advantage by disrupting established fuel flows and reducing refinery demand for crude. Operators, fuel buyers and suppliers should watch the scope and timing of any decision, along with Gulf Coast refinery runs, diesel inventories and gasoline prices.
OFS Sales Strategy
Oilfield service (OFS) teams should identify customers with high diesel use and review how fuel costs affect drilling, completions, trucking and field operations. Offer concrete ways to reduce fuel consumption, improve equipment uptime and make delivered costs more predictable. Avoid building a sales pitch around a ban until its terms are announced.
