President Donald Trump has explicitly ruled out a U.S. diesel export ban as of October 2, 2026, following a G7 agreement to release up to 100 million barrels of emergency diesel and crude reserves over four months. Record U.S. diesel prices above $6.50 per gallon, driven by supply disruptions from conflicts involving Iran and Ukraine, prompted earlier consideration of restrictions in September. Trump signaled support on September 22, with Treasury Secretary Scott Bessent reviewing full or partial options, though Energy Secretary Chris Wright and other officials stated an outright ban would not work, could reduce refinery output, and might raise gasoline and jet fuel prices. Industry groups opposed the measure, and the White House denied preparations for a 90-day ban. The administration has shifted toward voluntary measures and international coordination ahead of the November 3 midterms.
