G7 Leaders Agree to Release 100 Million Barrels of Oil and Diesel From Emergency Reserves

PARIS, OCTOBER 2, 2026 — It took weeks of pressure, one very public threat, and record diesel prices on both sides of the Atlantic. On Friday, the world’s seven leading industrial economies finally agreed to open the taps: a coordinated release of up to 100 million barrels of diesel and crude oil from emergency reserves, beginning immediately and spread over four months, supervised by the International Energy Agency.

The decision came out of an emergency G7 videoconference chaired by French President Emmanuel Macron, who holds the group’s rotating presidency. The IEA’s chief joined the call from the agency’s Paris headquarters. In their joint statement, the leaders cited “unprecedented volatility in oil markets,” warning that surging prices were threatening economic stability and the well-being of households and businesses.

The diesel gets priority. A “substantial” release of diesel is frontloaded into the first 20 days — a direct answer to the refined-fuel crunch that has pushed diesel to record highs. In September, U.S. diesel prices hit $6.53 a gallon, an all-time record; on Friday, average diesel at U.K. pumps broke £2 a litre for the first time, according to RAC figures. Prices fell significantly on international markets the moment the G7 announcement landed.

Why now

This was not a routine market intervention. It was a response to a stack of problems arriving at once: Russian diesel export restrictions extended through October, the near-closure of the Strait of Hormuz after Iranian military actions, and a war in the Middle East that has kept crude on edge since the spring. The constraint, energy analysts note, sits in refined product — specifically diesel — more than in crude itself.

And hanging over all of it was Washington. The Trump administration had spent days issuing an ultimatum: Europe releases its diesel reserves, or the United States considers a ban on diesel exports. Plans for a possible 90-day export ban surfaced in the press on September 23, and Trump told Fox News he was “thinking about it very seriously.” On his Truth Social platform Friday, the president claimed victory: “Europe has just agreed to release a massive amount of their heavily stocked Diesel Oil.”

The threat that forced the deal

A U.S. diesel-export embargo was Europe’s worst-case scenario. A ban would have triggered a severe supply crisis across the European Union, which depends on imported diesel — and some economists warned it would ultimately raise diesel prices inside the United States, too. “Such a ban would undermine our trust in the United States as a reliable partner,” a European Commission spokesperson said Friday morning.

Macron said the threat is now off the table, at least among the seven: “We have agreed that there will be no ban or restrictions on exports between G7 members,” he said after the call. “President Trump was very clear on this point.” The joint communique reaffirmed the commitment and called on all producers to refrain from export bans that could worsen market tensions. The White House is also reportedly preparing an executive order aimed at bringing diesel prices down, expected as soon as next week.

The March backstory

This is not the first coordinated release of the year. In March, in the early days of the Middle East war, IEA member countries pledged to make 400 million barrels available to slow the oil-price surge. Washington says it carried the load — providing nearly half of that release, with its latest 40-million-barrel tranche unlocked on Tuesday — and has criticized European members for not delivering all the volumes they promised. “Our European partners should accelerate delivery on their existing commitments,” Treasury Secretary Scott Bessent wrote on X on Thursday. “America is doing its part.”

Friday’s 100-million-barrel plan effectively turns those paper commitments into scheduled barrels on the water — and the IEA will be watching. The agency is tasked with monitoring full implementation of the March commitments, and G7 leaders requested a follow-up report within 20 days, including recommendations on further action and how the emergency reserves will eventually be replenished. Officials will meet through the IEA in the coming days to consider whether additional diesel releases are necessary.

What else was agreed

Beyond the barrels themselves, the leaders agreed to coordinate refinery maintenance schedules so large amounts of capacity are never taken offline at the same time, to temporarily increase refinery utilization where possible, and to encourage countries with substantial refining capacity to produce more refined fuels — diesel in particular. Macron added that members would work to increase production coordination and bring down transport costs such as tanker insurance, and push to get more tankers moving through the Strait of Hormuz.

For scale: 100 million barrels is roughly a single day of global oil demand. It will not remake the market by itself — but combined with the export-ban pledge, the refinery measures, and the IEA’s 20-day review, it is the most coordinated energy intervention the G7 has attempted this year. “This will hopefully settle the nerves in the global fuel markets and begin to bring prices down,” said Edmund King, president of Britain’s AA motoring association.
