What the Barrels Buy

The G7's 100 million barrels buy Europe four months of relief and a written promise that its allies will not cut off its diesel. They leave the three causes of the shortage where they were, and they run straight through the weeks after 3 November, when Washington has said strikes on Iran could resume.

On 29 September the head of the International Energy Agency told reporters in Dublin that another emergency release was not a priority. A third of the 400 million barrels pledged in March had still not reached the market. Three days later the G7 agreed to put out another 100 million over four months.

Two things moved in between. Brent crossed 100 dollars on 1 October as a third American carrier headed for the Middle East and China suspended fuel exports. And Washington leaned on its allies, weighing a 90-day diesel export ban to hold prices down before the midterms while its energy secretary offered a large European release as the alternative.

Brussels had its own word for that. On the day of the summit the European Commission pushed back against what it called American threats, and Macron had already called a diesel export ban catastrophic. The French proposal followed an overnight call with Trump. By the afternoon the G7 had its statement: 100 million barrels through the IEA, substantial diesel within 20 days, measures to raise refinery output and a pledge that partners will not restrict energy trade between them.

That last clause is the oddest line in the text. Allies wrote down a promise not to embargo one another's fuel because one of them had been weighing exactly that. Whether the threat or the price decided the timing is genuinely open. The Commission saw coercion. Traders saw 100-dollar crude and a Chinese export halt, and either would have justified a release on its own.

What the barrels cannot buy is a cure. The shortage has three causes and none of them sits in a storage tank. Russia's diesel output is down nearly 30 percent on last year and Moscow has restricted exports. China has stopped most of its fuel exports. Shipping through Hormuz is still disrupted. Crude from storage must be refined before it becomes diesel, which is why the statement adds refinery measures to the barrels.

The scale is modest. Spread evenly, 100 million barrels comes to about 830,000 barrels a day. One analyst puts Europe's entire diesel reserve at around 300 million barrels, enough for ten or eleven days of the world's diesel demand.

The calendar is worth watching. The diesel arrives in the first 20 days, before Americans vote on 3 November, and the release runs into early February. Trump has said strikes on Iran could resume after the midterms. Iranian officials say Tehran is reviewing plans to widen its targets beyond the region if they do. If that window opens, the shock lands on a buffer Europe has already begun to spend.

The barrels run out in February. The causes of the shortage have no such date.
