The Trump administration is considering restrictions on U.S. diesel exports as prices rise following oil-supply disruptions tied to the Iran war, even as Europe relies on record U.S. shipments. Options under discussion range from a 90-day export ban to incremental limits, with the oil and gas industry opposing the measures and warning that they would impair overseas competitiveness. A White House official said President Donald Trump is evaluating options to reduce diesel prices, which rose from $3.74 to $6.52 a gallon over the past year. U.S. diesel imports into the European Union rose by 1.5 million barrels a day in August, 50% above levels at the start of the conflict in February, according to ICIS. S&P Global Energy said U.S. diesel accounts for 10% of European consumption. Energy experts, administration allies and European officials warn that curbs could intensify competition for scarce cargoes, raise fuel costs, damage U.S. trade credibility and prompt importers to diversify their supply sources. The administration has not announced a final policy.
