US mulls diesel export ban; Europe faces 300k bpd supply gap

President Trump hinted at banning US diesel exports, a move that would remove roughly 300,000 barrels per day from global supply that no other producer can readily replace. Europe, which imports over a million barrels per day of diesel from outside the EU, would face acute supply tightness and price spikes. The ban is not yet enacted, and its scope and timing remain uncertain, but the signal alone pressures European fuel markets.
