Trump says he is looking very seriously at a diesel export ban

President Donald Trump said he is looking very seriously at banning US diesel exports^2,3. Semafor noted that the United States is the world’s biggest diesel producer and exporter, and that the threat has put buyers on alert¹. Energy Secretary Chris Wright said the administration is working with refiners on voluntary export curbs as an alternative to a ban^2,7.

The administration is not speaking with one voice. Wright publicly broke with the president, rejecting the idea of halting exports one day after Trump appeared to back it⁶. US officials spent the week qualifying the president’s comments⁸. The White House denied reports that it was preparing a 90-day prohibition⁵, and one explainer said Washington has clarified that a ban is not under consideration¹⁵. Industry groups have pushed back on the voluntary approach⁷.

Why it matters to investors

The price backdrop is already at extremes. UK diesel prices have hit an all-time high, according to the RAC⁹, with the average price of a litre at the pump standing at 198.32p¹⁰. The RAC attributed the surge to disruption of global oil supplies caused by the war with Iran⁹.

European diesel is soaring on refinery disruptions, supply shortages and geopolitical tensions, and a US export ban could make the continent’s crunch worse¹¹. The Times said the UK is at risk of diesel shortages if the ban proceeds¹². European officials have urged Washington to avoid what they called a concerning step⁸.

What to watch

Goldman Sachs has modelled the consequences. A note led by Daan Struyven, co-head of global commodities research, argued a White House diesel export ban could make gasoline more expensive rather than cheaper¹³, and a separate summary of the bank’s work noted it cut its GDP growth forecasts¹⁴.

The trade flows would move first. Shipping analysts expect export curbs to redraw tanker trades as Europe and Latin America hunt for fuel⁵. Inside the administration, Wright, Interior Secretary Doug Burgum and Treasury Secretary Scott Bessent are reported to be working on ways to ease diesel costs without a full prohibition¹⁶. Refiners’ response to the request for voluntary curbs is the next signal^2,7. Gasoline turned higher as the export-curb discussion continued⁷. One explainer set out what a ban would mean for energy markets globally and for India, a large buyer of refined products¹⁵.
