Leaders of the Group of Seven agreed at a video summit on October 2 to release up to 100 million barrels of crude oil and diesel from strategic reserves over the next four months, coordinated through the International Energy Agency (IEA) — "including a frontloaded substantial diesel release within the first 20 days." The process begins immediately. French President Emmanuel Macron, whose country holds the G7 presidency, announced the decision at a briefing. European diesel prices and Brent crude futures fell on the news.
The concession was extracted under pressure. The Trump administration had floated the possibility of banning diesel exports if European countries did not release more fuel from their strategic reserves — a devastating prospect for Europe, which leans heavily on imported diesel to cover a shortfall in domestic refinery output. The EU was still pushing back that morning: "A ban would not be beneficial to anyone," European Commission spokesperson Anna-Kaisa Itkonen said at a briefing. "It would undermine our trust in the United States as a reliable partner." Hours later, Europe signed on. Macron said members also committed to no energy export restrictions between G7 countries, and called on all producers to refrain from bans. Trump declared victory on social media: "Europe has just agreed to release a massive amount of their heavily stocked Diesel Oil. The process will begin immediately."
In March, after the outbreak of the Iran war, the IEA had already coordinated a 400-million-barrel strategic release. But Trump accused Europe of dragging its feet on delivering pledged barrels. The G7 statement left a loophole: the new 100 million barrels may include volumes pledged in March but never delivered — old debts rolled into the new announcement.
Prices have stayed elevated since the Iran conflict began. Brent hit $103.50 a barrel at the end of September; after the G7 announcement, November WTI closed at $91.11 on October 2, down $1.76 (1.90%), and December Brent finished at $102.25. Diesel's premium over crude — a closely watched gauge of market tightness — slumped to $69 a barrel from $76.77, per Bloomberg data. Hamad Hussein, senior climate and commodities economist at Capital Economics, assessed that if the recent increase in Middle East oil supply continues, the reserve release could be enough to push the overall market back into a slight surplus.
The G7 also agreed to coordinate refinery maintenance schedules so multiple plants don't go offline at once, and countries with significant refining capacity will be encouraged to maximize diesel output. Saudi Aramco is currently sending about 6 million barrels per day through its East-West pipeline — more than 80% of transport capacity recovered since last month's attack — as Middle East supply heals. Late in the trading day, reports that Saudi Arabia was preparing strikes against Iran-backed Houthi rebels in Yemen pared oil's losses.
This was an energy intervention and a political transaction. In recent weeks Trump escalated a trade war with Canada and suggested he might hit the EU with tariffs after the bloc deepened ties with Ottawa. Macron spoke with Trump on October 1 about bringing down diesel prices, then convened the G7 the next day. Europe traded reserves for a promise of no U.S. export ban — allies now doing business through threats.
