UK in Talks with Washington as Trump Threatens to Halt Diesel Exports

Britain has opened negotiations with the United States in an effort to head off a possible American ban on diesel exports, while simultaneously drawing up contingency plans in case the restrictions go ahead, Chancellor John Healey has confirmed.

The move comes as diesel prices in the UK climbed to an unprecedented level on Monday, driven by supply disruptions linked to the conflict between the US and Israel and Iran, as well as Russia's ongoing war in Ukraine. According to the RAC motoring organisation, the average cost of a litre of diesel reached 199.18p, edging past the previous record of 199.09p set in June 2022, shortly after Moscow launched its full-scale invasion of its neighbour.

Petrol has not been spared either, with a litre now selling for an average of 174.13p and continuing to creep upwards. The RAC described the diesel market as having entered "uncharted territory," warning that the situation highlights how vulnerable the UK remains to events unfolding far beyond its shores.

President Donald Trump fuelled concerns over the weekend when he said his administration was giving serious consideration to blocking diesel exports, a step that analysts believe is aimed at shielding American motorists from rising costs ahead of the critical midterm elections. US sources indicate that the White House sees such a measure as a way of easing pressure on domestic consumers, though the BBC has approached the White House for official comment.

The implications for Britain are considerable. Roughly one-third of the diesel consumed in the UK originates from the United States, meaning that any export ban would tighten an already strained market and almost certainly push pump prices even higher. Healey acknowledged that current diesel costs in Britain are "extreme," a description that will resonate with hauliers, farmers and households already grappling with a broader cost of living squeeze.

Speaking on the fringes of the annual Labour Party Conference in Liverpool, the Chancellor struck a diplomatic tone, stressing that London and Washington are working closely together. He said the government was making provision for the possibility that the UK may need to rely more heavily on its own stocks, adding: "We have our own stocks in the UK."

Healey also framed the fuel crisis as fundamentally a geopolitical problem requiring a geopolitical solution. In his view, the most effective way to stabilise prices would be a diplomatic settlement and an end to the fighting with Iran, which he said would either resolve the situation or at least significantly ease it. That message reflects a growing recognition in Whitehall that no amount of domestic tinkering can fully offset the consequences of war in the Middle East.

The roots of the current spike lie in more than seven months of conflict involving Iran, which has severely disrupted both the production and transportation of wholesale oil across the region. Because diesel is refined from crude, the surge in oil prices has fed directly into the cost of the fuel that powers much of Britain's freight, agricultural and construction sectors.

Politically, the timing could hardly be more awkward for the Chancellor, who is preparing what he has called a "breathing space" Budget for 28 October. Healey said he was "very aware" of the cost of living pressures bearing down on families as he finalises his fiscal plans.

Among the measures under scrutiny is the freeze on fuel duty, first introduced by the Conservative government in 2022. That freeze is due to lapse at the end of the year, with duty scheduled to rise by 3p in January and by a further 2p in March. Any increase would add to the pain at the pumps just as motorists are already contending with record diesel prices.

For the haulage industry, which operates on thin margins, the combination of soaring fuel costs and uncertainty over transatlantic supply would be particularly damaging. Fuel typically represents a substantial share of operating expenses for logistics firms, and sustained increases are often passed on to consumers through higher prices for goods, feeding broader inflationary pressure.

Energy analysts note that the UK's exposure is partly a consequence of decades of declining domestic refining capacity. While Britain still holds strategic fuel reserves, these are designed to cover short-term disruption rather than to replace a steady flow of imports. A prolonged American ban would therefore test the resilience of those stockpiles and could force the government to look to alternative suppliers in Europe, the Middle East or Asia, likely at a premium.

The diplomatic track remains the preferred option. Healey's remarks suggest that London is hoping Washington will weigh the alliance implications of restricting energy flows to a close partner, particularly at a moment when both countries are coordinating on wider Middle East policy. Whether that argument prevails will depend largely on domestic political calculations in the United States.

For now, British drivers face an uncomfortable autumn. Prices at the pump are at historic highs, a key source of supply is under threat, and the Budget at the end of October could determine whether fuel duty adds further to the burden. The Chancellor's message is that the government is preparing for the worst while working for a settlement that would make such preparations unnecessary.
