G7 Leaders Agreed to Release 100 Million Barrels From Reserves, With Diesel Front-Loaded Into the First 20 Days

The G7 pledged to release 100 million barrels of diesel and crude over four months and not to ban fuel exports, as diesel hits record prices during the Iran war.

The leaders of the G7 agreed on Friday 2 October to release 100 million barrels of diesel and crude oil from emergency reserves over four months, with a front-loaded, substantial release of diesel in the first 20 days. The release will begin immediately and be coordinated through the International Energy Agency. The group also pledged not to restrict energy exports among its members.

What was agreed

According to The National, the decision was announced in a joint leaders' statement issued through the office of French President Emmanuel Macron. Macron said: "We all committed to releasing strategic reserves in the amounts discussed, prioritising diesel, and we all pledged that there would be no export bans; President Trump was particularly clear on this point." The leaders also urged other producers to avoid export restrictions on energy products.

Why diesel

The urgency is about diesel rather than crude. The National reports that US diesel is at about $6.50 a gallon, nearly $3 higher than a year ago, and that European prices have reached about €2.24 a litre, up from €1.59 before the Iran war began on 28 February. Diesel is the fuel of freight, farming and construction, so high prices spread quickly into food and goods.

Oilprice.com reports that the plan is split, with European countries releasing about 50 million barrels of diesel and other IEA members supplying roughly 50 million barrels of crude. It also reports that the US administration had pressed Europe to draw down stocks and had floated diesel export restrictions. Trump said that Europe had agreed to release "a massive amount of their heavily stocked Diesel Oil." The outlet adds that the IEA had already coordinated a 400 million barrel release in March, after the war began, and that roughly two thirds of it has been delivered.

How the market took it

Markets reacted modestly. Oilprice.com says European gasoil futures fell by more than 4 percent and that Brent crude, which has traded above $100 a barrel through the conflict, slipped by about $3. The premium of diesel over crude also narrowed. Those moves are a sign that traders see the release as relief for diesel specifically, rather than a cure for the supply shock behind it.

The limits of a reserve release

Emergency stocks buy time, not supply. A release of 100 million barrels over four months is a substantial figure, but the underlying disruption, the effective closure of the Strait of Hormuz since the fighting began, remains. The agreement is as much about discipline as volume: by pledging no export bans, the G7 sought to stop the sort of national fuel hoarding that could drive prices higher still.

The test will come in the next three weeks. If diesel reaches pumps and depots in meaningful volume within the first 20 days, as promised, the political pressure on governments over fuel costs should ease. If it does not, leaders will face the same question on energy prices, with a smaller reserve to answer it.
