IEA’s “largest ever” is a pledge record; delivery accounts differ

本文另有中文版：IEA 4 億桶「史上最大」量的是承諾，各次事後交代並不一致

On 2 October the IEA said that about 325 million barrels of its 11 March collective action had been released so far, over 80 percent of the 400 million barrels pledged.

The Middle East war that began on 28 February prompted the action. By 11 March, the IEA said, exports through the Strait of Hormuz had fallen below 10 percent of their pre-conflict level. In 2025 an average of 20 million barrels a day of crude oil and products passed through the strait, around 25 percent of seaborne oil trade. The IEA’s 32 members agreed unanimously to make 400 million barrels available to the market from emergency stocks.

The headline of the IEA’s 11 March release called this the largest oil stock release ever. That label, issued on 11 March, rests on what members pledged. The IEA’s later accounts of the five earlier actions are a different matter: they use three different verbs, and they come at different moments.

Two conclusions follow. Pledges can be ranked: of the five actions with a stated total, 400 million barrels is the largest. The IEA pages do not give enough to rank final deliveries, because the accounts do not share a basis.

The IEA has called three releases the largest, each against a different yardstick

In 2022 the IEA described the 120 million barrels agreed on 1 April as “the largest collective action in the Agency’s history” (IEA FAQ, November 2022). The yardstick was a single action.

A closing note of 22 June 2023 used another yardstick. It said the two 2022 actions “amounted to 182.7 million barrels, the largest volume of emergency stocks ever released” (IEA closing note, 2023). Adding 62.7 million and 120 million gives 182.7 million, the same as the two pledges combined.

For 2026 the label appears in several IEA texts. The headline of the IEA’s 11 March release calls the action the “largest ever oil stock release.” Birol described it as an emergency collective action of unprecedented size. A 19 March IEA page calls it the largest ever by far. The IEA’s oil-security page lists it as the sixth and largest collective action.

Dividing 400 million by 182.7 million gives 2.19; 182.7 million equals the two 2022 pledges combined, and 400 million is a pledge. Adding the pledges of 2005, 2011 and the two 2022 actions gives 302.7 million barrels (60 + 60 + 62.7 + 120), and the 2026 pledge is larger. The 1991 action sits outside that sum, because the IEA pages give 2.5 million barrels a day and no total. So “largest ever” holds for pledges among the five actions with a total, and a citation should name its yardstick.

The appendix at the end of the article sets the six actions side by side, with the IEA’s own later wording in its sixth column.

“Over 80 percent” is measured against 400 million barrels, not the 426 million in the country table

A reader who sets the 11 March figure of 400 million barrels beside the 426 million in the 19 March country table gets a gap of 26 million barrels. Subtracting one from the other gives that gap, but the two numbers are not versions of one figure. The 400 million is the amount the IEA said on 11 March it would make available from emergency stocks. The 426 million is the total row of the country table, and it includes added production.

The table is headed as each country’s contribution to the 11 March action, in million barrels. The table lists the 426 million total as three components: public stocks 280, obligated industry stocks 119, added production 28. Adding the three columns gives 427, one more than the printed total, and the page does not say why. Obligated industry stocks are stocks that companies hold under a government obligation, and governments must authorise their use in a crisis. Canada’s 23.6 million barrels all sit in the added-production column.

The same page says the release will be largely crude oil, with Europe contributing mainly refined products, and that it is being “complemented by additional production from countries in the Americas.” The IEA says the splits between public and industry stocks, and between crude and products, remain subject to change. That caveat covers the splits. The page does not say the total is provisional.

Adding the public and industry columns gives 399 million barrels. The IEA does not say that 400 million equals those two columns. The page does not reconcile 400, 399 and 426 line by line.

On 2 October the IEA gave its own base: “representing over 80 percent of the 400 million barrels originally pledged” (IEA statement of 2 October, as quoted by Euronews). Euronews describes the 325 million as oil and oil-derivative products. The statement does not say whether that figure includes added production.

So when a progress percentage appears, the first question is which number is the base.

Five earlier actions, three verbs: how the IEA later accounted for them

On 2 September 2005, after Hurricane Katrina disrupted supply from the Gulf of Mexico, IEA members agreed to make available the equivalent of 60 million barrels of crude oil and products. The action closed on 22 December. The IEA’s closing page says “Nearly all of the barrels were provided to the market” (IEA closing page, 2005), and it names two routes: stocks and increased indigenous production. That wording therefore includes added production.

A 2005 report by the Congressional Research Service (CRS) describes something narrower. The United States offered 30 million barrels of Strategic Petroleum Reserve crude for sale. On 14 September the Department of Energy announced it had sold 10.8 million barrels of sweet crude and 0.2 million barrels of sour crude, and bids for another 8.2 million barrels were rejected. That is one sale by one country, not the IEA’s account of the whole action.

On 23 June 2011, 28 members agreed to release 60 million barrels over the following month, after Libyan supply was disrupted (IEA release, republished by resilience.org (2011)). Eleven years later the IEA’s 2022 FAQ looked back: “In 2011, the IEA’s members released 60 million barrels.” The same page says members released the same amount in 2005. Both figures equal the volumes agreed at the time. The FAQ gives no delivered volume for either action.

A month after the 2011 action, a review by Indonesia’s energy ministry (ESDM) said the action was not yet complete and stocks were still entering the market. That is a second-hand account, written eleven years before the FAQ look-back.

The 2022 accounts came while the actions were still running. The IEA’s FAQ of 16 November 2022 says the vast majority of the 182.7 million barrels pledged “has effectively been made available to the market” by the end of October. On 27 October Keisuke Sadamori, the IEA’s director of energy markets and security, told S&P Global the same and added that both actions remained active (S&P Global interview via Hellenic Shipping News (2022-10-27, Japan time)).

The closing note of 22 June 2023 says deliveries of oil from public reserves were completed by the end of 2022. Neither the FAQ nor the closing note breaks the volume down by country or to a common date.

The 2022 IEA contribution table (page image) is headed Total Contribution. It shows 182,677 thousand barrels in total, 74 percent from public stocks and 26 percent from industry. The United States accounts for 90,559 thousand barrels, all public stock. The image has no delivered column and no added-production column.

The IEA’s account of 1991 stops at the start. On 17 January, the day allied air strikes on Iraq began, the IEA activated a pre-agreed plan to release 2.5 million barrels a day. It extended the action on 28 January and gave members more flexibility. The pages give no total, end date, member count or country shares.

In 2026 the IEA reported running totals while the action was still open

On 21 July Birol said that “around 290 million barrels have been released by IEA Member countries” (Birol statement, 21 July), with more still flowing to the market.

On 2 October the IEA put the figure at about 325 million barrels. The statement was tied to Birol’s remarks at the G7 leaders’ video meeting (IEA statement of 2 October, quoted by ANI and Euronews, reported by AFP/CNA from 3 October). Both figures are approximations for the action as a whole.

Counting calendar days, 21 July falls 132 days after 11 March and 2 October falls 205 days after it. The 11 March release set no common period, and each country decided its own timetable. In the same week AFP reported that Birol told reporters in Dublin on Tuesday that a big chunk of the stocks had been released, and its account adds that about a third was still to come to market. The share has no barrel count and no stated base, so it cannot be set against the two barrel figures.

Both totals show how far the action as a whole had gone. Neither shows what any one country delivered.

The G7 agreed to release 100 million barrels. Does that make 500 million?

On Friday 2 October, G7 leaders agreed to release 100 million barrels through the IEA, starting immediately and running four months. The statement includes a “front-loaded substantial diesel release within the first 20 days” (G7 joint statement, quoted by The National and ANI).

Reports describe the 100 million barrels in different terms: diesel and crude, diesel and strategic reserves, oil and diesel. Euronews also describes it as oil and oil-derivative products. Financial Times (republished by the Irish Times) says the statement does not make clear how much is crude and how much is diesel.

The link to the March action is a separate question. CNA, relaying AFP, writes that the G7 did not say whether the 100 million barrels include the 75 million barrels of the March pledge still to be released, or are additional. Euronews says the same. The statement itself says the G7 is “Taking into account commitments that have already been fulfilled” (G7 joint statement, as quoted by the Irish Times).

The answer is no, not by simple addition. The 100 million barrels is a pledge in a separate statement, and that statement does not give its relation to the March action. The appendix therefore carries it as a note, not as a seventh row.

400 million barrels wins on pledges; the IEA pages do not give enough to rank what was finally delivered

The accounts differ in scope. The 2005 closing wording includes added production, because the page names increased indigenous production. The 2026 country table has an added-production column. The 2022 contribution table, as the page image shows it, splits the total into public and industry stocks and into crude and products, and has no added-production column. The pages on the other actions do not say whether added production is included.

The IEA itself uses “released” for earlier actions. The 2023 closing note applies it to 182.7 million barrels, and the 2022 FAQ applies it to 2005 and 2011. So the earlier figures cannot be dismissed as mere pledges.

But the timing does not match. The 325 million barrels is an approximation for an action still open on 2 October. The 182.7 million barrels is the closing note’s description of two actions combined. The IEA pages give no 2022 figure aligned with 2 October, and no country-level results. That does not mean the IEA misreported any action. It means the accounts share no common basis.

“Largest ever” holds for pledges among the five actions with a stated total. On how fast the stock was released, the IEA’s public pages give no data. On how much, the figures can only be set side by side on different bases, which does not rank the six actions by what was finally delivered.

Appendix: Six IEA collective stock releases, 1991–2026

Note: the G7’s agreement of 2 October to release 100 million barrels through the IEA is a pledge in a separate statement. It is not a seventh row (see the G7 section above).

Frequently Asked Questions

What does the IEA’s “largest ever” measure?

Three different yardsticks: a single action in 2022, two actions combined in 2023, and a single pledge in 2026. See the section “The IEA has called three releases the largest”.

What is the IEA’s “over 80 percent” a share of?

Of the 400 million barrels pledged on 11 March, not of the 426 million total in the 19 March country table. See the section “Over 80 percent”.

How did the IEA later describe the five earlier actions?

It used three verbs, provided, made available and released, at moments ranging from mid-action to look-backs more than a decade later. See the section “Five earlier actions, three verbs”.

Should the G7’s 100 million barrels be added to the 400 million?

Not by simple addition. The G7 statement does not say how the 100 million relates to the part of the March pledge not yet released. See the section “The G7 agreed to release 100 million barrels”.

Sources

Scope and version: pledge comparisons rest on IEA pages and on reports quoting them, and statements about what the IEA pages do not say are limited to the pages listed below. The 2005 daily rate comes from CRS. The 2011 status a month after the action comes from a report by Indonesia’s energy ministry, a second-hand account. G7 wording comes from news reports. The 325-million-barrel statement is dated 2 October (Birol at the G7 leaders’ video meeting, per ANI and Rio Times) and was reported from 3 October (Euronews, which wrote that the IEA “said Saturday”; CNA; AFP). The IEA’s own page for that statement is not among the sources. The 2022 country table is an image on the IEA page, with an Excel file attached that this article does not use. The statements here that the table has no delivered column and no added-production column are limited to what the image shows. If the file has a delivered column on the same basis as the 2026 “released”, the 2022 and 2026 comparison and the conclusion would need to be redone. The IEA’s 2011 release was read only in a republished copy on resilience.org.
