Record-high US diesel prices above $6.50 per gallon, driven by supply strains from conflicts involving Iran and Ukraine, prompted President Trump to publicly back export restrictions in late September 2026 ahead of November midterms. A Politico report on preparations for a 90-day ban triggered market reactions, but White House officials and Energy Secretary Chris Wright promptly denied any formal prohibition, emphasizing that a blanket ban would likely reduce refinery runs and raise gasoline and jet fuel prices. The administration instead signaled interest in voluntary industry measures to boost domestic supply. No official announcement has followed, leaving trader-implied probabilities for an announcement by October 31 at around 13-14%. Upcoming midterm elections and ongoing refinery consultations could still shape policy direction before year-end.
