IEA Stock Release to Exceed 400 Million Barrels as Over 20 Million of Diesel Is Fast-Tracked
The 32 member countries of the International Energy Agency (IEA) have released approximately 330 million barrels of emergency oil stocks under the collective action agreed in March, and the total will now exceed the 400 million barrels originally pledged, the agency’s Governing Board said on 15 October. The Board agreed to accelerate the remaining volumes, with specific plans already in place, including over 20 million barrels of diesel to be released as soon as possible.
Some members have already released more than they pledged in March and others intend to do so, which is what takes the total above 400 million barrels, according to the statement. The Board agreed to take all necessary steps to complete the remaining releases of around 100 million barrels “in a timely manner consistent with national circumstances”. It encouraged members holding oil production and refining capacity to boost supply of crude and refined products, particularly diesel, and underlined the importance of the free flow of energy trade. The decision builds on the G7 leaders’ statement of 2 October and on the March 2026 Collective Action taken in response to the Strait of Hormuz crisis. The Board noted the Secretariat’s latest assessments, which point to continued tightness in oil markets, notably for diesel.
430 million barrels on the agency’s approximate figures
Taken together, the 330 million barrels already released and the 100 million barrels still to be completed come to 430 million barrels on the agency’s approximate figures. That is 30 million barrels, or 7.5 percent, more than the 400 million barrels agreed unanimously on 11 March, on our calculation. The country contributions table the agency published on 19 March summed to 426 million barrels, of which 28 million, or 6.57 percent, were production increases from countries in the Americas, led by Canada’s 23.6 million barrels, on our calculation.
The released figure stood at approximately 325 million barrels when the agency briefed G7 leaders on 2 October and again after the member governments’ meeting on 7 October, against approximately 330 million now. Over the 218 days from 11 March to 15 October, releases averaged 1.51 million barrels a day on the approximate total, on our calculation.
On the agency’s approximate figures, the diesel tranche is 20 percent of the remaining volume, on our calculation. On 7 October the agency put members’ public emergency oil stocks at around 1.1 billion barrels, including over 200 million barrels of diesel.
The March 2026 Collective Action, position on 15 October
| Item | Million barrels | Share of the 400 million pledge |
|---|---|---|
| Pledge agreed, 11 March | 400 | 100% |
| Released so far | 330 | 82.5% |
| Remaining to complete | 100 | 25% |
| Released plus remaining | 430 | 107.5% |
| Diesel to be accelerated | 20 | 5% |
Released and remaining volumes are the agency’s approximate figures from its 15 October statement, and the diesel volume is its “over 20 million barrels”; the 430 million total and all shares are our calculation.
Over 20 million barrels of diesel in a tight market
The agency’s October Oil Market Report, published on 14 October, sets out why diesel is the pressure point. Global gasoil and diesel exports fell to 4.7 million barrels a day in September, nearly 700,000 barrels a day below a year earlier, as combined net exports from the Middle East and Russia dropped by 1.3 million barrels a day to 820,000. Global diesel demand contracted by 750,000 barrels a day year on year to 28.7 million in the third quarter.
Measured against those flows, the accelerated diesel tranche equals at least 4.26 days of global gasoil and diesel exports at the September rate, and at least 15.38 days of the Middle East and Russian export loss, on our calculation. Those figures compare its size with the flows and do not forecast its effect on the market.
Over 20 million barrels of diesel against the market
| Benchmark | Level | Over 20 million barrels equals at least |
|---|---|---|
| Global gasoil and diesel exports, September | 4.7 mb/d | 4.26 days |
| Middle East and Russia export loss, September | 1.3 mb/d | 15.38 days |
| Global diesel demand, third quarter | 28.7 mb/d | 0.70 days |
| OECD gasoil stocks, July | 565 mb | 3.54% |
Levels from the Oil Market Report of 14 October; the export loss is year-on-year. The diesel tranche is the agency’s “over 20 million barrels”, so each figure is a minimum. Days and the stock share are our calculation.
Prices show the same strain: wholesale diesel reached all-time highs that the report put at around 220 dollars a barrel in Europe and the United States, and benchmarks remain nearly double the price of crude. The report expects gasoil supply to fall short of demand in the fourth quarter and sees replenishment of lost inventories as unlikely before the second half of 2027.
Gulf producers lead the September supply rise
World oil supply rose 2.5 million barrels a day in September to 102.3 million, driven by Gulf producers, the report said: OPEC+ gains of 2.1 million barrels a day were led by Saudi Arabia, and the UAE drove the increase outside OPEC+. Saudi Arabia’s supply rose to 8.3 million barrels a day in September from 5.97 million in August, a gain of 2.33 million barrels a day or 39.03 percent, and stood at 68.54 percent of the 12.11 million barrels a day of sustainable capacity listed for the kingdom, on our calculation. Crude oil exports from Gulf producers have reached over 75 percent of their pre-war levels, the report added.
Why it matters: Diesel is the fuel through which the supply shock reaches the wider economy. The October report says record diesel prices are raising the cost of goods and affecting real incomes, economic activity and inflation, and that the gasoil market will remain tight well into 2027, with the balance dependent on a recovery of product supply from the Middle East. By lifting the total release above 400 million barrels and committing over 20 million barrels of diesel as soon as possible, member governments are directing part of their emergency stocks at the diesel tightness the Secretariat has flagged.
Outlook: The Secretariat will continue to monitor completion of the March 2026 Collective Action and will inform G7 leaders and the Governing Board on any further action needed, based on an updated oil market assessment focused on diesel. With around 100 million barrels still to come, the delivery pace of the diesel tranche over the coming weeks will show how quickly the remaining volumes move from pledge to market.
