US President Donald Trump announced on October 9 that Russia would immediately provide more than 300,000 metric tons of diesel, equivalent to approximately 2.25 million barrels (mmbbl), for US and international markets to help curb rising fuel prices. Washington also temporarily suspended sanctions on Russian fuel, which had been intended to limit Moscow’s income amid its war on Ukraine.

US diesel prices have climbed 70% since the US and Israel launched their war against Iran on February 28, with the national average reaching $6.28 per gallon on October 8, according to the AAA motorist group. The increase has intensified inflationary pressures and created a political challenge for Republicans ahead of the November 3 congressional elections. Diesel is essential for agricultural operations, residential heating, and freight transportation.

Following Trump’s announcement, US diesel futures dropped nearly 5% to $4.64 per gallon. However, analysts cautioned that the additional Russian volumes might not be sufficient to maintain the decline. The administration has already taken steps to improve availability by urging allied countries to release emergency fuel reserves and allowing broader access to red-dyed diesel, which is generally reserved for off-road use and exempt from federal fuel taxes. The US exports approximately 1.5 million barrels of diesel per day.

In September 2026, Trump backed a proposal to restrict US diesel exports as domestic prices surged above $6.50 per gallon amid supply disruptions linked to the wars in Iran and Ukraine. However, the White House denied plans for a 90-day export ban, while Energy Secretary Chris Wright warned that such restrictions could disrupt refinery operations and drive up gasoline and jet fuel prices. The administration instead explored alternative measures to increase domestic supply.
