US President Donald Trump said on Thursday, 2 October 2025 that his administration may ask European countries to release some of their diesel stockpiles as it scrambles to ease pressure on fuel prices amid disruptions to global supplies. The remarks came during a brief exchange with reporters while Trump was travelling through Texas and Oklahoma for events focused on his administration's economic and trade policies.

What Trump Said

When asked whether he would approach European nations to release diesel reserves and help bring prices down, Trump said: 'We may do that.' He added that 'prices are coming down,' signalling cautious optimism even as his administration continues to weigh multiple options.

On the possibility of restricting US diesel exports — a measure he had discussed in a Sunday interview — Trump said: 'Well, we're thinking about it very seriously. That can oftentimes lead to a little bit of an increase on gasoline for cars. So we're looking at it very seriously. We may do it.'

Russia's Role in the Supply Crunch

Trump attributed the primary strain on global diesel supplies not to Middle East instability but to the ongoing Russia-Ukraine conflict. 'The big problem is the refineries in Russia are being blown up,' Trump said. 'This isn't really a Middle Eastern problem. This is more of a Russia problem, that Ukraine and Russia are going at it, and Ukraine is blowing up diesel refineries in Russia because they do a lot of the refining.'

The assessment marks a notable framing shift, placing the Ukraine war's impact on energy infrastructure at the centre of the administration's supply analysis.

The Export Restriction Debate

The administration has been examining whether curbing US refined petroleum exports could boost domestic diesel availability and lower prices for American consumers. However, such a move carries significant risks: the United States is a major exporter of refined petroleum products, and a restriction could ripple through international fuel markets.

More than 30 US business, manufacturing, and energy groups have formally opposed potential export curbs, arguing they could discourage domestic refinery production and ultimately push costs higher — the opposite of the intended effect.

The European Stock Option

Seeking releases from European diesel reserves would represent a distinct approach — focused on increasing available global supply rather than restricting US exports. Trump did not specify on Thursday which European countries he might approach, how much diesel he would seek, or whether preliminary discussions with European governments had already begun.

Why Diesel Prices Matter

Diesel is a politically and economically sensitive fuel because it powers the trucking, agricultural, construction, and industrial sectors. Price increases in diesel tend to cascade through supply chains, raising transportation costs for goods and ultimately hitting consumer prices. Any sustained elevation in diesel costs can amplify broader inflationary pressures at a time when the administration is already under scrutiny over its economic stewardship.

The administration has yet to announce a final decision on any of the options under review. Further clarity is expected as discussions with domestic industry groups and, potentially, European counterparts develop.
