Trump’s Fuel Export Ban Threat Sends European Diesel Soaring

President Donald Trump’s push to ban American diesel exports sent European prices for the fuel surging, while U.S. futures came under pressure. Europe relies heavily on U.S. diesel exports near 2 million barrels a day as Middle East disruptions and Russian export curbs tighten supplies. With flows from the region’s top supplier at risk, European diesel’s premium to Brent crude jumped to more than $95 a barrel on Sept. 23, marking a record in Bloomberg data dating back to 2011. This indicator, known as crack spread, is closely watched by central bankers seeking to tame inflation, while the equivalent measure in the U.S. weakened.

Trump’s threat arrives as Europe is already dealing with the loss of diesel shipments from the Middle East, alongside Russian export curbs that have further tightened the global fuel market. The U.S. has emerged as Europe’s primary overseas supplier, with American exports of the fuel surging to a weekly record near 2 million barrels a day last month. While the Middle East conflict has reduced petroleum product flows through the Strait of Hormuz to a trickle, Moscow is set to extend a ban on most diesel exports beyond the end of the month as Ukraine continues targeting Russia’s oil refineries.

The ongoing conflicts have driven fuel prices up faster than crude, stoking inflation across the Atlantic. In the U.S., rising prices at the pump have become a major source of frustration ahead of midterm elections. Trump stated that he has encouraged his advisers to support a ban on U.S. diesel exports. Treasury Secretary Scott Bessent noted that officials are evaluating whether a full or partial ban would work. Meanwhile, a key oil industry group, the American Petroleum Institute, cautioned against the move, warning that it could lower American fuel production and damage the global economy.
