IEA Proposes Largest Ever Oil Release from Strategic Reserves

The International Energy Agency is reaching for a tool it has used only five times in five decades — and this time, the scale is without precedent.

As crude oil prices surge past $90 a barrel and the Strait of Hormuz remains effectively shuttered by conflict, the IEA has proposed the largest coordinated release of emergency oil stockpiles in its 52-year existence [1]. The plan, first reported by the Wall Street Journal and confirmed by multiple diplomatic sources, would exceed 100 million barrels in the first month alone — dwarfing every previous collective action the agency has undertaken [2].

But a growing chorus of energy analysts warns that even a historic draw from the world's strategic reserves may prove insufficient against the sheer magnitude of the supply disruption now confronting global markets.

The Crisis That Triggered the Proposal

The immediate catalyst is the near-total closure of the Strait of Hormuz, the narrow waterway between Iran and Oman through which roughly 20.9 million barrels of oil flow daily — approximately 20% of global petroleum liquids consumption and nearly 27% of the world's seaborne oil trade [3][4].

Since February 28, 2026, when the United States and Israel launched joint military strikes on Iran, the strait has become impassable for commercial shipping. Iran's Islamic Revolutionary Guard Corps responded by issuing warnings prohibiting vessel passage, and while no physical blockade was erected, the withdrawal of maritime insurance has achieved the same effect [5]. Tanker traffic dropped approximately 70% within days, with more than 150 vessels anchoring outside the strait to avoid risk. Traffic has since fallen to near zero [6].

The consequences have been immediate and severe. Iraq has cut 1.5 million barrels per day of production as it runs out of storage capacity. JPMorgan estimates that production cuts across the Gulf could exceed 4 million barrels per day by the end of this week if the strait remains closed [7]. Wood Mackenzie pegs the current disruption at roughly 15 million barrels per day of Gulf oil and oil products supply removed from the market [8].

What the IEA Is Proposing

The IEA convened an extraordinary meeting of its 32 member nations on Tuesday, March 10, with a decision expected the following day [9]. Under the agency's emergency response framework, the proposed release would be adopted unless even a single member country objects — a mechanism designed for speed but vulnerable to political holdouts [2].

The proposal calls for releasing more than 100 million barrels in the first month, with the total program potentially reaching 300 to 400 million barrels — representing 25% to 30% of the approximately 1.2 billion barrels held in public emergency stockpiles across IEA member nations [10]. An additional 600 million barrels are held in industry stocks under government mandates, providing a further buffer [11].

The IEA secretariat is expected to propose multiple scenarios based on projected market impact. Critically, the agency's outreach extends beyond its membership: officials have signaled that coordination with non-IEA members, including China and India — both massive importers of Gulf crude — will be essential to any effective response [2].

However, implementation will not be immediate. Even after political consensus is reached, technical negotiations over total volume, country-by-country allocations, and release timing must follow [1].

The G7's Cautious Dance

The diplomatic choreography leading to the IEA proposal reveals the tension between urgency and caution that has characterized the global response.

G7 energy ministers held an emergency call on Sunday, March 9, but stopped short of committing to a coordinated release. Several member governments argued that no physical shortage of crude had yet materialized — that the price surge was driven by risk premiums and speculation rather than actual supply gaps [12]. The ministers instead asked the IEA to assess the situation and propose options [13].

By Wednesday, March 11, the tone had shifted. G7 energy ministers stated they "stand ready" to take "all necessary measures" in coordination with the IEA, signaling in-principle support for the use of strategic reserves while stopping short of a binding commitment [14]. The careful language — support "in principle" rather than an outright decision — reflects ongoing disagreements about scale and timing [15].

A History of Emergency Releases

The IEA has coordinated collective oil stock releases only five times since its founding in 1974 in the wake of the Arab oil embargo. Each previous action was smaller and addressed more contained disruptions:

• 1991 — Gulf War: 75 million barrels offered, with the U.S. assigned to release 33.75 million barrels from the SPR [16].
• 2005 — Hurricane Katrina: A coordinated release targeting 60 million barrels of crude and refined products, with the U.S. contributing 20.8 million barrels [16].
• 2011 — Libyan Civil War: 60 million barrels released, including 30 million from the U.S., to offset Libya's production shutdown [16].
• 2022 — Russia-Ukraine War (two releases): A combined 182 million barrels released across two tranches, the largest collective action to date. The U.S. alone released roughly 180 million barrels from its SPR over the course of the year [16][17].

The current proposal would exceed the 2022 total in its first month alone, underscoring the severity of the disruption the IEA is trying to address.

The Skeptics' Case

Many energy analysts question whether even a record release can meaningfully offset the scale of the current supply shock.

"It doesn't look like the oil market thinks that 'largest ever' release of strategic reserves will help much against current crisis," SEB analyst Bjarne Schieldrop observed on Tuesday [8]. The market's initial reaction bore this out: after an initial 11% dip on reports of the IEA proposal, oil prices rebounded, with Brent crude settling around $91 per barrel [18].

The arithmetic is stark. Goldman Sachs analysts calculated that a release of the proposed magnitude would offset only about 12 days of the estimated 15.4 million barrels per day in disrupted Gulf exports [8]. If the Strait of Hormuz remains closed for weeks or months, strategic reserves would be drawn down rapidly with no guarantee of replenishment.

The U.S. Strategic Petroleum Reserve, the world's largest, holds approximately 416 million barrels — roughly 58% of its 714-million-barrel capacity [19]. This represents a significant improvement from the 40-year lows reached after the 2022 releases, when the reserve fell below 350 million barrels. The Biden administration repurchased 32.3 million barrels at prices below $79 per barrel, and the Trump administration has continued modest refills [17][19]. But the SPR remains far from full, and a major release now would push inventories back toward historic lows.

Historical evidence on the price impact of reserve releases is mixed. A U.S. Treasury analysis of the 2022 release found it lowered gasoline prices by 17 to 42 cents per gallon [20]. But much of the eventual price decline that year owed more to demand destruction and recession fears than to the additional supply itself. OPEC's own analysis has noted that reserve releases "consistently moderated price spikes rather than prevented them" when underlying disruptions were structural [8].

The Asian Vulnerability

The Strait of Hormuz crisis hits Asia hardest. In 2024, 84% of crude oil and 83% of liquefied natural gas transiting the strait was destined for Asian markets, with China, India, Japan, and South Korea accounting for 69% of all Hormuz crude flows [3].

India faces particularly acute exposure: more than half of its LNG imports are Gulf-linked, and a significant share of its supply contracts are Brent-indexed, meaning a Hormuz-driven crude spike simultaneously lifts both its oil import costs and LNG contract prices [7].

Japan and South Korea, both IEA members, will be expected to contribute to any coordinated release — even as they face among the most severe supply disruptions. This creates a tension at the heart of the IEA proposal: the countries with the greatest need for emergency stocks are also those being asked to deplete them.

The Limits of the Toolkit

The fundamental challenge confronting the IEA is one of category: strategic petroleum reserves were designed to bridge temporary supply disruptions, not to substitute for a major producing region's output over an extended period.

At 15 million barrels per day of disrupted supply, even the full 1.2 billion barrels of IEA emergency stocks would be exhausted in roughly 80 days — less than three months. And releasing the entirety of global strategic reserves is neither politically feasible nor strategically advisable, as countries must maintain minimum stockpiles for their own national security.

The effectiveness of any coordinated release ultimately depends less on the volume of oil injected into markets and more on whether the underlying conflict begins to de-escalate [8]. If the Strait of Hormuz reopens within weeks, a large reserve release could successfully cap the price spike and prevent economic damage. If the closure persists, even the largest stockpile draw in history will prove a temporary measure against a structural supply gap.

As one senior IEA official told reporters: the reserves can buy time, but they cannot buy peace.

What Comes Next

The IEA's 32 member nations are expected to reach a decision on the proposed release by the end of this week. If no objections are raised, the release mechanism can be activated rapidly — though physical oil deliveries will take additional weeks to reach markets [2].

Parallel diplomatic tracks are in motion. The IEA secretariat has initiated outreach to China and India, the world's largest and third-largest oil importers respectively, to explore coordinated action beyond IEA membership. Neither country is an IEA member, but both hold significant strategic reserves and face acute exposure to the Hormuz disruption [2].

The oil market, meanwhile, is pricing in both the potential release and the probability that it won't be enough. Brent crude traded in a $86–$92 range on Tuesday, well above the $71 per barrel seen before the conflict erupted on February 28, but below the $119 peak reached on Monday before reports of the IEA proposal emerged [18][12].

For consumers, the implications are already arriving at the pump. U.S. gasoline prices have risen sharply in the past two weeks, and European energy costs are climbing. The question facing the IEA and its member governments is not whether to act, but whether any action within their power can match the scale of the crisis now unfolding in the Persian Gulf.
