The UK is holding urgent talks with the United States over President Donald Trump’s possible diesel export ban. Meanwhile, the government is preparing contingency measures to protect fuel supplies and limit the impact on consumers.
Chancellor John Healey said Monday that Britain is already discussing the issue with US officials. At the same time, the government is preparing plans to use national fuel stocks if American exports are restricted.
Healey described current UK diesel prices as “extreme” and warned that a US export ban could push prices even higher, according to the BBC.
US Diesel Ban Could Hit UK Supply
The potential restrictions pose a significant risk because the United States is an important supplier of diesel to Britain. According to UK government data, the US accounted for about 31% of the UK’s diesel imports in 2025.
As a result, any major reduction in American exports could affect transport and logistics across Britain. In addition, industries that depend heavily on diesel could face higher operating costs.
The UK government is therefore examining several options before any possible US restrictions take effect. For example, officials could tap national fuel reserves if supplies become tight.
Trump Considers Export Restrictions
Trump has said his administration is taking the possibility of an export ban “very seriously.” However, no final order had been announced as of September 28.
The proposal is linked to efforts to reduce fuel costs in the United States ahead of the November 4 midterm elections. Nevertheless, uncertainty remains over whether Washington will introduce a complete ban or impose more limited restrictions.
Politico reported that some US sources said the White House had indicated to senators that a blanket 90-day ban was unlikely. Even so, Trump has not formally ruled out other measures affecting diesel exports.
US Treasury Secretary Scott Bessent has also said officials are examining both full and partial restrictions. Meanwhile, US diesel prices have reached record levels, increasing pressure on the administration.
UK Prepares for Possible Fuel Shock
The UK’s preparations come as global energy markets remain sensitive to developments in the Middle East. In particular, recent hostilities involving Iran have added pressure to fuel markets and raised concerns about wider supply disruptions.
Healey also linked the situation to broader diplomatic efforts. He suggested that a settlement could help ease the wider crisis, including progress toward ending the fighting involving Iran.
For Britain, the immediate concern is the potential effect on diesel supplies and prices. Therefore, officials are preparing for several possible scenarios while continuing discussions with Washington.
Ultimately, the UK hopes diplomatic engagement can prevent major disruption. However, the contingency plans show that London is preparing for the possibility that US policy could quickly affect fuel supplies, transport costs and businesses across Britain.
