A brewing fuel crisis is sending shockwaves through global energy markets, as former President Donald Trump has confirmed he is considering imposing a ban on United States diesel exports and has floated the idea of calling on European nations to draw down their own emergency strategic diesel reserves to offset any supply disruption.
Trump’s remarks come amid already sky-high diesel prices that hit record levels on British forecourts this week, driven by a cascade of geopolitical disruptions that have squeezed refined fuel supplies across the globe. The ongoing conflict related to Iran has put persistent upward pressure on crude and refined product markets, while Russia’s invasion of Ukraine, Western sanctions on Russian energy, and recent Ukrainian strikes on Russian domestic refining capacity have combined to drastically cut off traditional European diesel supplies from Russia. More recently, the closure of the Strait of Hormuz — a critical chokepoint that carries roughly 20% of the world’s daily oil and gas trade — following the outbreak of the US-Israel conflict in Iran in February has sent global petroleum product prices soaring even higher.
The United Kingdom, which meets more than half of its total diesel demand through imports, relies heavily on American supply: 31% of the UK’s imported diesel comes from the US, after European imports from Russia were drastically reduced over the past year. With November’s US midterm elections approaching and American consumers already grappling with steep domestic fuel price increases, Trump has framed an export ban as a quick fix to bring down pump prices for US voters. Banning exports would flood the domestic US market with surplus diesel, a shift that experts agree would drive a significant drop in prices for American drivers, truckers and businesses. Scott Bessent of the US Treasury has already publicly urged Europe to prepare for immediate release of its own strategic diesel reserves, arguing that American stakeholders should not be forced to bear the burden of global market volatility as prices climb.
But energy analysts warn that a US export ban would drastically exacerbate price pressures across Europe and other importing nations unless alternative supplies can be secured immediately. The US is one of the world’s top diesel exporters, shipping between 1.2 million and 1.5 million barrels of refined diesel to global markets every day. While the majority of these exports go to Latin America, European nations including France, the Netherlands and the UK have become increasingly dependent on US diesel after cutting off purchases from Russia and reducing imports from Middle Eastern sources. Compounding the market stress, Chinese refiners have reportedly halted all diesel exports for October to prioritize domestic supply, further tightening available global stock.
In response to the threat of a US export ban, UK officials have already launched urgent consultations with European Union counterparts, who are scheduled to hold a dedicated meeting on the crisis Friday. UK Energy Minister Martin McCluskey held a coordination call with European energy officials Thursday, and a government source familiar with the talks told reporters that coordinated contingency planning with EU partners is underway. The source noted that unused emergency reserves remain from a coordinated strategic stock release carried out earlier in the year, and a UK government spokesperson emphasized that the country’s diesel supply chain remains diverse and resilient. While the UK government has stressed there is no immediate risk of shortages, it has acknowledged that prices are likely to climb further in coming weeks.
Under International Energy Agency rules, all member states including the UK are required to hold emergency oil stocks equivalent to 90 days of net imports. EU member states are mandated to hold reserves covering at least 61 days of domestic consumption, bringing the bloc’s total emergency crude and refined fuel stocks to nearly 109 million tons, around one-third of which is held as diesel and related refined products. A European Commission spokesperson confirmed that multiple high-level discussions are already underway, including direct contacts with senior officials in the US administration.
David Fyfe, chief economist at energy intelligence firm Argus Media, warned that cutting off US diesel exports to global markets would almost certainly trigger another sharp spike in international diesel prices. Unlike gasoline, diesel requires more complex refining processes, and demand is notoriously inflexible because the fuel powers the global haulage, agriculture and freight sectors that cannot quickly reduce consumption. The UK’s own domestic refining sector can meet all of the country’s petrol demand, but it does not produce enough diesel to cover domestic needs. Latest UK Department for Transport data puts the number of diesel-powered vehicles on British roads at 15.1 million as of the end of June, down slightly from 15.7 million a year prior, with 9.8 million of those being passenger diesel cars.
This article was clarified on October 2: An earlier version incorrectly stated the International Energy Agency’s governing board would hold a meeting on Friday. The IEA later issued a statement clarifying no such meeting was planned, and the announcement was made in error by a European Commission spokesperson, leading to the removal of the incorrect line.
