President Donald Trump said Russia had agreed to immediately supply more than 300,000 tons of diesel to U.S. and global markets after a call with President Vladimir Putin. The announcement came as diesel prices approached record highs and ahead of the Nov. 3 congressional elections, which will determine control of Congress. Trump said the plan also includes 500,000 tons in November, 1 million tons immediately afterward and another 3 million tons within a short period. Russia confirmed its readiness to supply oil and petroleum products to U.S. and global markets, while the Treasury Department said it would lift sanctions on Russian diesel. A temporary general license covers Russian diesel loaded onto tankers as of Friday, with U.S. sanctions not applying to those deliveries until April 2027. Russia had banned diesel exports amid domestic shortages and attacks on its energy infrastructure, but said it would begin lifting the restrictions ahead of schedule. Andy Lipow, president of consulting firm Lipow Oil Associates, expressed skepticism that Russia could deliver the promised volumes. Analysts have said the additional supply may not significantly reduce prices because it could displace fuel previously destined for other markets. The U.S. national average for diesel was $6.28 a gallon, according to AAA, after reaching a record $6.52 on Sept. 22.
