Senate Majority Leader John Thune said the United States could consider banning diesel exports to help reduce domestic prices as fuel costs rise amid disruptions linked to the Iran war. The national average diesel price reached $6.3103 per gallon on Wednesday, according to the American Automobile Association (AAA). GasBuddy analyst Patrick De Haan opposed a rushed move, warning that export controls could send a powerful signal to markets and drive away traders. He said diesel could reach $7 per gallon in the coming days, with fuel costs expected to jump over the next 48 hours as the Iran war and Russia-Ukraine conflict disrupt supply. Russia had already banned diesel exports through September 30, while President Donald Trump urged Ukrainian President Volodymyr Zelenskyy to stop attacks on Russian oil assets. A suspected Houthi strike on Saudi Arabia's East-West pipeline and Saudi Arabia's reported request for U.S. military support add to concerns about energy-supply disruptions.
