President Donald Trump’s administration considered restricting U.S. diesel exports in September and early October 2026 amid record highway diesel prices above $6.50 per gallon, driven by global refining shortfalls tied to the Russia-Ukraine conflict and disruptions from U.S. military operations involving Iran. Congressional proposals for immediate or price-triggered bans advanced amid pressure from farmers, truckers, and midterm election dynamics. On October 2, however, Trump explicitly ruled out an export ban after G7 partners agreed to release up to 100 million barrels of emergency diesel stocks. The administration instead pursued an October 5 executive order allowing tax-deferred use of dyed off-road diesel on highways and signaled interest in voluntary flow adjustments. No ban has been announced, and Energy Secretary statements have emphasized alternatives to outright restrictions.
