The European Union is warning the Trump administration that restricting U.S. diesel exports could raise problems on both sides of the Atlantic as Washington considers ways to bring down fuel prices.

European Commission spokesman Olof Gill said Thursday that the EU is concerned by reports of a possible U.S. diesel export ban, including restrictions on shipments to Europe. He said high-level discussions between Brussels and Washington are underway and urged the two sides to consult before taking actions affecting shared energy markets.

The concerns follow reports that the Trump administration was considering a 90-day suspension of diesel exports as U.S. fuel prices have surged. President Donald Trump said Tuesday that he had raised the idea with his administration and that a decision could come quickly.

U.S. Energy Secretary Chris Wright, however, has pushed back against an outright ban. Wright said Wednesday that a broad prohibition would be a blunt tool that could reduce refinery output and put additional pressure on gasoline and jet fuel prices. The administration has indicated that other restrictions or voluntary measures remain under consideration.

U.S. diesel prices reached an average of about $6.52 per gallon this week, according to AAA, up sharply from a year earlier. The surge has increased pressure on the administration to find ways to lower fuel costs for American farmers, truckers and other businesses that rely heavily on diesel.

Europe has also become increasingly dependent on imported diesel, with the United States supplying roughly half of the European Union's diesel imports in August. European officials said there is not currently a concrete diesel shortage across the bloc but warned that losing U.S. supplies could force European buyers to compete for replacement cargoes in an already tight global market.

U.S. energy and business groups have likewise opposed broad export restrictions, arguing that limiting overseas sales could reduce incentives for domestic refiners to produce fuel. The American Petroleum Institute and other industry organizations have warned that the policy could ultimately tighten supplies and increase costs rather than provide lasting relief.

The administration therefore faces competing concerns as it weighs its options: reducing the domestic price burden from record diesel costs while avoiding disruptions to refinery operations and international fuel markets.

For now, an outright export ban remains unconfirmed.
