Trump Weighs Diesel Export Ban as US Urges Europe to Tap Reserves

The United States has signalled it may impose restrictions on diesel exports, with President Donald Trump confirming he is giving the idea serious consideration as global fuel costs surge. Speaking over the weekend, Trump said an export ban was under active review, and on Thursday he added that he might formally request European nations to unlock portions of their own diesel stockpiles to ease mounting pressure on world markets.

The possibility of an American export ban has prompted urgent diplomacy on both sides of the Atlantic. Treasury Secretary Scott Bessent publicly pressed European partners to act without delay, arguing that fuel reserves should be made available immediately to cushion the effects of ongoing supply disruptions. In a social media post, Bessent said European allies should speed up delivery on commitments they had already made and free up additional supplies. He also warned that American farmers, truckers and businesses should not be forced to shoulder the burden of spiralling prices.

The debate carries significant political weight in the US, where voters will head to the polls in November for midterm elections that will determine control of Congress. Trump is expected to campaign heavily across the country in support of Republican candidates as he seeks to retain majorities in both the House and the Senate. With fuel costs a top concern for voters, keeping surplus diesel at home could offer immediate relief at the pump — a message with clear electoral appeal.

Washington's threat to curb exports has already triggered a response in Europe. On Thursday, Britain held talks with European partners about the possibility of releasing diesel reserves should an American ban take effect. UK Energy Minister Martin McCluskey joined a call with counterparts from across the continent to discuss a coordinated approach. A source familiar with the discussions described preparing a joint response alongside EU countries as prudent, noting that some European reserves remain from a coordinated release of strategic fuel stocks earlier in the year.

The UK government sought to reassure the public, with a spokesperson saying the country has a diverse and resilient supply chain and that engagement with international partners and the domestic fuel industry continues. Ministers have stressed there is no cause for alarm about potential shortages, although they acknowledge prices are likely to climb further. The European Commission confirmed that extensive talks were under way, including high-level contacts with the US administration, describing a busy schedule of calls and meetings on the diesel situation.

The pressures stem largely from the conflict in Iran. Since the outbreak of the US-Israel war there in February, global petrol and diesel prices have risen sharply. The closure of the Strait of Hormuz, a chokepoint that normally carries roughly a fifth of the world's oil and gas, has driven up the cost of refined products. An export ban imposed by Russia, another major diesel supplier, has compounded the strain on international markets.

The US occupies a pivotal role in global diesel supply, shipping between 1.2 million and 1.5 million barrels abroad every day. Analysts caution that halting those flows could backfire by pushing international prices sharply higher. David Fyfe, chief economist at Argus Media, said cutting off American supply would likely cause prices elsewhere to skyrocket, undercutting the intended benefit of domestic relief.

In the UK, the effects are already visible at filling stations. Diesel prices reached an all-time high this week, with the RAC reporting average pump prices of 199.79p per litre — a steep rise from 142.38p. The motoring organisation's figures underscore how quickly costs have escalated for British drivers and businesses alike.

Diesel presents particular challenges because it is harder to refine than petrol and is essential to haulage and agriculture, making demand difficult to reduce in the short term. Britain relies heavily on imports for its diesel needs: while the country's four refineries produce more than enough petrol to satisfy domestic demand, they cannot manufacture sufficient diesel. According to the Department for Transport, there were 15.1 million diesel vehicles on UK roads at the end of June, down from 15.7 million a year earlier, including 9.8 million diesel cars compared with 10.4 million twelve months before.

The coming weeks will prove critical. European governments must weigh whether to release strategic reserves, while the White House decides whether to proceed with a measure that could reshape global fuel flows. For consumers on both sides of the Atlantic, the stakes are immediate and tangible, with pump prices, freight costs and food prices all hanging on decisions being made in Washington and Brussels.
