What is happening?
The UK is trying to prevent a possible US ban on diesel exports, while preparing for the disruption if one goes ahead. Chancellor John Healey told the BBC that the government is in discussions with US authorities and is making contingency plans.
No ban has been formally announced. The White House said President Donald Trump is evaluating options to bring down prices at US pumps.
Why would a US decision affect the UK?
The UK depends on the US for about a third of its diesel imports. A restriction on those exports would reduce one source of supply for British fuel markets, potentially adding to price pressures as suppliers look for alternatives.
The effect would not necessarily be limited to diesel sold directly from the US. Fuel is traded in international markets, so changes in supply can affect prices more broadly. The source does not provide an estimate of how much a ban would raise prices or how long any disruption would last.
Why are diesel prices already high?
UK diesel prices reached an average of 199.33p per litre on Monday, according to the RAC. That exceeded the previous high of 199.09p recorded in June 2022, after Russia launched its full-scale invasion of Ukraine.
The BBC reported that supply pressures were linked to the conflict between the US and Israel and Iran, as well as Russia’s war with Ukraine. The source also said the conflict involving Iran had disrupted the production and transportation of wholesale oil in the region over the previous seven months.
Petrol prices were also rising, with an average of 174.23p per litre cited in the report.
What has Donald Trump said?
Trump said at the weekend that his administration was thinking seriously about banning diesel exports. US sources cited by the BBC said the idea was being considered as a way to reduce prices for domestic consumers ahead of the US midterm elections.
However, the White House said there had been no official policy announcement and that Trump was evaluating all the options available.
How is the UK government responding?
Healey said the UK was working closely with the US and preparing for a possible stoppage. He also said the UK had its own fuel stocks that could be used if necessary.
The chancellor described current UK diesel prices as “extreme” and said the government needed to create “breathing space” before the Budget on 28 October. His comments indicate that the government is treating a potential US export restriction as an additional risk to an already pressured market, rather than as a confirmed shortage.
What else could affect prices?
UK fuel duty is another factor. A freeze introduced by the Conservative government in 2022 is due to expire at the end of 2026. Under the schedule described in the source, duty is due to rise by 3p in January and by a further 2p in March.
Those increases are separate from the possible US export ban. Any final effect on drivers, businesses and households would depend on several factors, including whether a ban is introduced, how long it lasts and whether other supplies can replace US imports.
What should readers understand?
- A US diesel export ban is being considered, not implemented, according to the report.
- The UK is exposed because about one-third of its diesel imports come from the US.
- UK diesel prices have already reached a record average, according to the RAC figures cited by the BBC.
- The UK says it is pursuing talks with the US while preparing to use domestic stocks if needed.
- The source does not establish how much a ban would increase UK prices or whether it would lead to an actual shortage.
