G7 Agrees to Release 100 Million Barrels From Oil and Diesel Reserves

Leaders of the Group of Seven (G7) industrialised nations said on October 2, 2026, that they will release up to 100 million barrels of oil and diesel from strategic reserves, coordinated through the International Energy Agency (IEA), according to a joint statement reported by Al Jazeera, NBC News, oilprice.com and BNN Bloomberg.

The G7 statement, quoted by BNN Bloomberg, reads: "We will implement our commitments with a coordinated release through the IEA of 100 million barrels (MB) to begin immediately over 4 months." The plan calls for a frontloaded, substantial diesel release within the first 20 days by G7 members and partner countries, with further releases to be discussed in the coming days.

Why now: an Iran war and a diesel squeeze

The release follows months of rising fuel costs tied to a US-Israeli war with Iran that Al Jazeera reports began on February 28, 2026, and has constricted shipping traffic through the Strait of Hormuz. NBC News reported that diesel prices have risen about 70% since February, with the US national average reaching $6.37 a gallon on the day of the announcement after hitting a record $6.52 in September, according to BNN Bloomberg, which dated that record to September 22, 2026.

Oilprice.com reported additional pressures on supply, including outages at Middle Eastern refineries, damage to Russian refining capacity, and China's decision to suspend October fuel exports to preserve domestic stocks. Europe, which consumes more diesel than it refines, has become increasingly reliant on US imports, the outlet said.

Trump's pressure on Europe

According to Al Jazeera and NBC News, President Trump had threatened to restrict US diesel exports unless European governments released their own emergency stocks. Trump wrote on Truth Social that Europe had agreed to release what he described as a massive amount of its stockpiled diesel and that the process would begin immediately, NBC News reported. BNN Bloomberg added that the G7 also agreed not to impose export restrictions on each other's fuel, rejecting calls for a US diesel export ban.

NBC News reported that French President Emmanuel Macron hosted the videoconference among G7 leaders that produced the agreement. NBC also cited US Treasury Secretary Scott Bessent as framing the action as a way to avoid American businesses alone absorbing the cost of a global shortage.

How the barrels are expected to split

Accounts of the agreement vary in detail. Oilprice.com reported that European nations are expected to supply 50 million barrels of diesel while other IEA members contribute 50 million barrels of crude oil. BNN Bloomberg's report of the same G7 statement did not specify a crude-versus-diesel breakdown, saying only that the full 100 million barrels would be released over four months through the IEA.

Both NBC News and oilprice.com noted that this release follows an earlier, larger one: a 400-million-barrel IEA-coordinated release in March 2026, made after the Iran war began, according to oilprice.com.

Market reaction

Oilprice.com reported that European gasoil futures fell more than 4% and Brent crude dropped roughly $3 to below $100 a barrel after the announcement, with diesel's premium over crude narrowing from $76.77 to about $69 a barrel. NBC News reported that Brent crude remained above $100 a barrel as of Friday and was up more than 60% since the start of the year, citing oil analyst Andy Lipow, who said the release could temporarily cut US diesel prices by about 25 cents a gallon but would do little to expand refinery capacity.

What is still unclear

• The exact country-by-country breakdown of how much crude versus diesel each G7 or partner nation will release.
• Whether additional releases beyond the initial 100 million barrels will follow; the G7 statement says this will be discussed "in the coming days."
• How much of the relief will reach retail diesel prices in the US and Europe, given that analysts cited by NBC News say the move does not add refining capacity.
