The global diesel market is facing severe supply pressure after wars in the Middle East and Ukraine disrupted shipments from regions that normally provide almost a third of worldwide diesel exports. The resulting shortage has driven prices higher in the United States and internationally, increasing costs for businesses, farmers and households. In response, the Trump administration is considering export restrictions or an outright ban to curb domestic prices. Analysts warn that limiting U.S. exports could have a potentially catastrophic effect on global diesel supplies.
