UK joins EU allies in emergency talks over diesel reserves as Trump threatens export ban

Britain's government scrambled into emergency talks with European counterparts on Thursday as Donald Trump threatened to cut off American diesel supplies unless the continent released its strategic reserves. The calls involved ministers from the UK, the European Commission, Germany, France, Italy, and Ireland—all wrestling with the same pressure from Washington: unlock your emergency stockpiles or face an export ban.

The Trump administration's ultimatum came wrapped in economic logic. Global diesel prices had soared, and with US midterm elections in November, the White House wanted to show it could bring relief at the pump. Treasury Secretary Scott Bessent posted on social media that European partners should "immediately" make additional supplies available. Trump himself, speaking from a campaign stop in Texas, was blunt: "We may do that. They have some diesel." The administration had grown frustrated with France and Germany, believing they hadn't followed through on earlier commitments to release oil and petrol stocks. Now it was threatening to weaponize America's own export capacity to force compliance.

For Britain, the threat carried particular sting. The UK produces about 70 percent of the diesel it consumes domestically, but that leaves a gap—roughly a third of last year's diesel imports came from the United States. If Washington cut off that supply, British fuel prices would spike sharply. On Wednesday alone, the average price of a litre of diesel hit a new record high of 199.72 pence, according to the RAC motoring body. Chancellor John Healey had already called the situation "extreme" and said the government was in talks with the US to prevent a ban.

Europe's predicament ran deeper than simple supply and demand. The continent faced a genuine dilemma: release reserves now to lower prices and appease Washington, or hold them in case the Iran conflict—which had already disrupted supplies through the Strait of Hormuz and sent Brent crude above $101 a barrel—worsened over the winter heating season. Brent had traded at roughly $72 a barrel in February. The International Energy Agency was being brought into the conversation. The European Commission confirmed that member states would hold urgent talks on Friday to discuss a coordinated response.

Chris Wright, the US energy secretary, framed the release as a practical solution. "This is a time for a coordinated release of diesel stores as we go into harvest season and we go into winter heating oil season," he told Fox News. "Now's the time to bring more diesel to the market, and that diesel is available." UK Energy Secretary Miatta Fahnbulleh had been in contact with Wright to raise British concerns. A US official told reporters it was "in Europe's best interest" to cooperate.

Trump had also taken an unusual step: urging Ukraine's president, Volodymyr Zelenskyy, to pause strikes on Russian oil refineries, worried that further damage would push prices even higher. Russia had already extended its own diesel export ban through the end of October following Ukrainian attacks on refineries. The irony was sharp—the US president was asking Ukraine to hold back military operations to protect global fuel supplies.

Elizabeth de Jong, chief executive of the trade group Fuels Industry UK, captured the broader anxiety. "The UK continues to need fuels—from transport to chemicals, agriculture and defence," she said, adding that the latest threat showed Britain "cannot solely rely on overseas production for domestic energy security." A government spokesperson offered reassurance about supply diversity and international engagement, but the calculus was clear: Britain was caught between two pressures—Washington's demand for reserves to be released, and the need to keep those same reserves intact for a potentially severe winter if the Middle East conflict deepened.
