Fifty Days of Oil

DHAHRAN — The International Energy Agency announced on March 11 the largest coordinated release of emergency oil reserves in history — 400 million barrels, drawn from government stockpiles and obligated industry inventories across 32 member nations. The number sounds vast. It is not. Divided by the 8 million barrels per day that the Strait of Hormuz closure has removed from global supply, those 400 million barrels cover exactly 50 days. The Iran war, now in its third week, has no ceasefire in sight. President Donald Trump has suggested operations could continue for another three to four weeks. The arithmetic is unforgiving: the world’s oil safety net was designed for hurricanes and pipeline ruptures, not for a full-spectrum naval blockade of the chokepoint through which one-fifth of the planet’s crude oil once flowed.

What follows is an examination of every major strategic petroleum reserve on earth — their size, their drawdown rates, their political constraints, and the brutal mathematics that govern how long each one can last. The conclusion challenges a comforting assumption that has underpinned energy security policy since the 1970s: that stockpiling enough oil would always buy enough time for diplomacy to work. In the Strait of Hormuz crisis of 2026, diplomacy is not working, and the clock that started on March 11 is already running down.

What Does 400 Million Barrels Actually Mean?

The figure sounds enormous because it is the largest coordinated release in the IEA’s 52-year history. But in a world that consumes approximately 103 million barrels of oil per day, according to the IEA’s most recent monthly oil market report, 400 million barrels represents less than four days of total global consumption. The relevant calculation, however, is not against total consumption but against the specific supply shortfall created by the Hormuz closure.

Before the Iran war began on February 28, approximately 20.5 million barrels of oil and petroleum products transited the Strait of Hormuz every day, according to the U.S. Energy Information Administration. Of that total, roughly 3.5 million barrels can be rerouted through overland pipelines — principally Saudi Arabia’s 5-million-barrel-per-day East-West Pipeline to the Red Sea terminal at Yanbu and the UAE’s 1.5-million-barrel-per-day Abu Dhabi Crude Oil Pipeline to Fujairah. The net shortfall, after pipeline diversions, ranges between 8 million and 16.5 million barrels per day depending on the degree of Hormuz blockade effectiveness.

The IEA itself projects the March shortfall at 8 million barrels per day, a figure that assumes partial pipeline rerouting is working. At that rate, the 400-million-barrel release buys exactly 50 days of coverage — roughly early May 2026 — before the reserves are exhausted and the world faces the shortfall with no cushion at all.

The distinction between government and industry stocks matters. Government-controlled reserves like the U.S. Strategic Petroleum Reserve can be released by executive order. Obligated industry stocks — oil held by private companies under national stockpiling mandates — require separate legal mechanisms and corporate cooperation. In several European countries, the process of converting obligated stocks into actual barrels on the market can take weeks, not days.

The Six IEA Emergency Releases in History

The March 2026 release is only the sixth time the IEA has triggered its collective action mechanism since the agency was founded in 1974 in response to the Arab oil embargo. Each previous release was smaller, shorter, and triggered by a less severe disruption. The pattern reveals an organisation stretching a Cold War-era toolkit to cover crises it was never built to handle.

In January 1991, the first Gulf War prompted a release of 33.75 million barrels authorized by President George H.W. Bush. The U.S. Department of Energy ultimately delivered 17.3 million barrels over a 45-day period. The disruption was real but manageable: Iraqi and Kuwaiti production — roughly 4.5 million barrels per day combined — was offline, but Saudi Arabia compensated by increasing its own output from 5.4 million to 8.5 million barrels per day within weeks. The IEA release proved almost unnecessary. Oil prices, which had spiked to $41 per barrel in October 1990, fell to $20 by February 1991.

In September 2005, Hurricane Katrina knocked out 1.5 million barrels per day of Gulf of Mexico production and shut 10% of U.S. refining capacity. President George W. Bush authorized a 30-million-barrel release. Prices stabilised within weeks because the disruption was geographically limited and refineries came back online within months.

In June 2011, the Libyan civil war removed approximately 1.5 million barrels per day from the market. President Barack Obama authorized 30 million barrels of sweet crude, matching the grade Libya produced. The disruption lasted months, but other OPEC members — particularly Saudi Arabia — increased production to compensate.

In 2022, Russia’s invasion of Ukraine prompted two separate IEA collective actions totalling 182.7 million barrels, by far the largest response before 2026. But the Russian disruption was partial and gradual: Russian oil never fully left the market, instead finding buyers in India and China at discounted prices. The actual supply loss was roughly 1-2 million barrels per day at its peak.

The coverage ratio column reveals the core problem. In every previous crisis, the IEA released enough oil to cover the disruption for weeks or months, buying time for production to recover or alternative supplies to materialise. In 2026, the coverage ratio has collapsed to 50 days because the disruption is four to five times larger than anything the system was designed to handle. The Hormuz closure is not a leak in the global oil pipeline. It is the pipe itself being cut.

The American Reserve Is Already Depleted

The United States holds the world’s largest single strategic petroleum reserve in four underground salt dome caverns along the Gulf of Mexico coast in Texas and Louisiana. At its peak in 2009, the SPR held 726.6 million barrels. Today it holds approximately 415 million barrels — 57% of its authorised 714-million-barrel capacity.

The decline did not begin with the Iran war. Between 2021 and 2023, the Biden administration released approximately 180 million barrels from the SPR to combat domestic fuel price inflation following Russia’s invasion of Ukraine, drawing the reserve down to a 40-year low of roughly 347 million barrels by the summer of 2023. A partial refill programme brought it back to 415 million barrels by early 2026, but the reserve remained at barely half capacity when Iran’s missiles began flying.

On March 12, the Department of Energy announced a drawdown of 172 million barrels — the single largest U.S. release in history — beginning March 16 and running over 120 days. The SPR’s maximum discharge rate is 4.4 million barrels per day for the first 90 days, declining to 3.8 million barrels per day for the subsequent 30 days as cavern pressure drops. In practice, however, the 172-million-barrel release will flow at roughly 1.4 million barrels per day — fast enough to matter, too slow to close an 8-million-barrel-per-day gap.

After the 172-million-barrel release, the SPR will hold approximately 243 million barrels, its lowest level since the reserve was being filled in the early 1980s. That remaining inventory represents roughly 74 days of U.S. net crude imports — well below the IEA’s requirement that members hold at least 90 days of net imports in reserve. The United States, the architect of the global strategic reserve system, will be in technical violation of its own rules.

The IEA’s requirement that members hold 90 days of net oil imports was set in 1974, when the assumption was that any supply disruption would last weeks, not months. The Hormuz crisis has exposed a system built for a world that no longer exists.

The Reserve Depletion Matrix

The true measure of vulnerability is not how much oil each country holds in reserve, but how quickly that reserve depletes against the country’s specific shortfall from the Hormuz closure. A country that imports 80% of its oil through Hormuz faces a fundamentally different timeline than one that sources most of its crude from the Americas or West Africa.

The following matrix maps IEA member countries by three variables: total strategic reserves, daily import dependence on Hormuz-transiting crude, and the resulting number of days their reserves can sustain normal consumption in a total Hormuz closure scenario. This calculation — the Hormuz Vulnerability Quotient — produces results that are, for several major economies, far more alarming than headline reserve figures suggest.

The matrix reveals a stark divide. European nations and the United States, which source most of their oil from the Americas, the North Sea, and West Africa, face manageable timelines measured in many months. Japan and South Korea — which import between 70% and 85% of their crude from the Persian Gulf, according to the Japan Petroleum Energy Center — face depletion within 43 to 60 days after contributing their share to the IEA release. For Tokyo and Seoul, the 400-million-barrel release is not a solution. It is a countdown.

Japanese Prime Minister Sanae Takaichi acknowledged the crisis on March 13, stating that Japan faced “an exceptionally high level of dependence” on Middle Eastern oil and would begin releasing national reserves immediately. South Korea’s Ministry of Trade, Industry and Energy made a similar announcement, though without specifying volumes.

Why Is Asia Running Out of Oil First?

Asia’s vulnerability to the Hormuz closure is not a surprise. It is a structural condition that energy analysts have warned about for decades. What changed in March 2026 is that the theoretical risk became an operational emergency overnight.

Japan imports approximately 3.1 million barrels of crude oil per day, of which 2.4 million — 77% — transits the Strait of Hormuz, according to data from Japan’s Agency for Natural Resources and Energy. South Korea imports 2.6 million barrels per day, with 1.8 million — 69% — flowing through the Strait. India’s dependency is even more extreme: of its 4.7 million barrels per day of imports, approximately 3.5 million — 74% — originates from the Persian Gulf, though some is now being partially rerouted through longer African supply chains.

The geographic concentration is not an accident. Persian Gulf crude is chemically suited to Asian refineries, which were built to process medium-sour grades — the dominant type produced by Saudi Arabia, Iraq, Kuwait, and the UAE. Switching to alternative sources is not simply a matter of finding new suppliers. It requires recalibrating entire refinery complexes, a process that takes months and costs hundreds of millions of dollars.

Saudi Aramco has asked its Asian buyers to develop dual supply plans using both Red Sea and Hormuz-routed cargoes, Reuters reported on March 12. The request is an implicit acknowledgement that the Yanbu pipeline route through the Red Sea cannot fully compensate for lost Hormuz volumes. The East-West Pipeline has a nominal capacity of 5 million barrels per day but an effective throughput — accounting for maintenance, crude grade restrictions, and Red Sea loading bottlenecks — closer to 3.5 million, according to industry estimates published by S&P Global Commodity Insights.

For Asian economies, the question is not whether strategic reserves can bridge the gap. It is what happens when those reserves run out and the war continues. At current depletion rates, Japan faces potential rationing by late April, and South Korea by mid-April, according to Bloomberg’s energy supply modelling, published March 14.

The Drawdown Gap No One Will Discuss

A strategic reserve is only as useful as the speed at which its contents can reach the market. The 400-million-barrel headline obscures a mechanical reality: not all of those barrels can flow simultaneously, and the combined global drawdown rate is far less than the supply gap it is meant to fill.

The U.S. SPR can discharge at a maximum of 4.4 million barrels per day through its pipeline network and marine terminals along the Gulf Coast. Japan’s reserves, stored in a mix of underground rock caverns and above-ground tank farms, have an estimated drawdown rate of approximately 1 million barrels per day. South Korea’s capacity is roughly 500,000 barrels per day. European IEA members, whose reserves are dispersed across hundreds of smaller facilities, can collectively release an estimated 1.5 to 2 million barrels per day.

Add these together and the maximum global emergency drawdown rate is approximately 7.4 to 7.9 million barrels per day — close to but still below the 8-million-barrel-per-day shortfall. In theory, a full-speed drawdown by every IEA member simultaneously could nearly close the gap. In practice, no country will empty its reserves at maximum rate because doing so leaves zero margin for further disruptions.

The realistic drawdown rate — accounting for countries holding reserves back against future contingencies — is approximately 5 to 5.5 million barrels per day. That leaves a permanent uncovered gap of 2.5 to 3 million barrels per day, roughly equivalent to the entire daily oil consumption of France and Germany combined. This gap is why Brent crude remains above $100 per barrel despite the largest reserve release in history, and why EU energy ministers called an emergency meeting on March 16 to discuss further measures.

The United States Department of Energy has been transparent about its own limitations. In its March 12 announcement, it confirmed the 172-million-barrel release would take approximately 120 days to deliver at planned discharge rates — a tacit admission that the barrels will not arrive fast enough to prevent price spikes and localised shortages in the near term. It takes 13 days after a presidential order for the first SPR barrels to reach the open market, the Department of Energy confirmed.

How Does the Hormuz Crisis Change Saudi Arabia’s Strategic Leverage?

Saudi Arabia does not maintain a strategic petroleum reserve in the conventional sense. It does not need one. The Kingdom sits atop 12.2% of the world’s proved oil reserves — 258.6 billion barrels, according to the BP Statistical Review of World Energy 2025 — and maintains approximately 2 million barrels per day of spare production capacity even in wartime conditions, according to Aramco’s March 2026 guidance to analysts.

What the Hormuz crisis has done is transform Saudi Arabia from a supplier among many into the supplier of last resort. With Iraqi exports suspended after Iranian drone strikes near Basra, Kuwaiti production offline following airspace closures, and UAE volumes reduced by damage to the Fujairah terminal, Saudi Arabia is the only major Gulf producer with both the spare capacity and an operational export route that bypasses Hormuz entirely.

The Kingdom’s East-West Pipeline — a 1,200-kilometre artery connecting the Eastern Province oil fields to the Red Sea — was built after the 1980-88 Tanker War for precisely this scenario. Its existence means Saudi Arabia can continue exporting approximately 3.5 million barrels per day even while Hormuz remains closed. That volume does not fully replace the Kingdom’s pre-war export level of roughly 7.5 million barrels per day, but it ensures a continuous revenue stream at prices far above pre-war levels. With Brent crude at $103 per barrel — compared to roughly $72 before the war — each barrel Aramco ships through Yanbu generates 43% more revenue than it did three weeks ago, as Aramco’s wartime earnings call revealed.

The SPR drawdowns across the developed world further consolidate Saudi leverage. As IEA members deplete their reserves, their dependence on Saudi production increases. A Japan that has exhausted its strategic stockpile by late April will be entirely dependent on whatever crude Saudi Arabia can route through the Red Sea. The Kingdom becomes not just a supplier but a lifeline — and lifelines command a premium.

Can Refineries Even Process Emergency Oil?

A barrel of crude from the U.S. Strategic Petroleum Reserve is not interchangeable with a barrel from Saudi Arabia’s Ghawar field. The SPR stores two grades: sweet crude (low sulphur) and sour crude (high sulphur). Asian refineries — particularly in Japan, South Korea, and India — are configured to process medium-sour grades that dominate Persian Gulf production. The SPR holds approximately 247 million barrels of sour crude and 168 million barrels of sweet crude, according to DOE inventory data.

The crude quality mismatch creates a second-order problem. If Asian refineries receive sweet crude from the SPR release, they must adjust their processing configurations — blending, changing catalyst ratios, and recalibrating desulphurisation units — to handle oil with different chemical properties. This is technically feasible but operationally slow. The Japanese Petroleum Association warned on March 13 that switching to non-Gulf crude grades would reduce effective refining throughput by 8-15% for the first six to eight weeks of the transition.

European refineries face a different but related problem. Many continental European refiners were already processing more expensive non-Russian Urals crude after the 2022 sanctions. Adding SPR-sourced oil to their slate creates a third crude grade in their processing mix, with associated logistical and quality-management costs that erode the price benefit of the reserve release.

The SPR Was Never Designed for This

The conventional view of strategic petroleum reserves — shared by energy ministers, IEA officials, and financial markets — is that they exist to bridge temporary supply disruptions. Release enough oil to cover the gap, the theory goes, and prices stabilise, panic subsides, and the market buys time for the disruption to resolve. Every previous IEA collective action reinforced this model. The 1991 release bridged a disruption that ended within weeks. The 2005 release covered a hurricane recovery measured in months. Even the 2022 releases addressed a Russian supply reduction that was partial and never total.

The Hormuz crisis breaks this model because the disruption is not temporary, not partial, and not amenable to the market self-correction that strategic reserves are meant to enable. The Strait is not closed because of a natural disaster that will pass. It is closed because Iran’s Islamic Revolutionary Guard Corps Navy has mined the waterway, is actively threatening vessel traffic with anti-ship missiles, and has declared that no ship will transit without Iranian permission, as the failure to assemble a Hormuz-clearing coalition has demonstrated.

The evidence supports a more unsettling conclusion. Strategic petroleum reserves were designed for supply disruptions — temporary interruptions in a fundamentally functioning market. What the Hormuz closure represents is supply destruction: the permanent removal of a major transit route from the global oil network for an indeterminate period. Against supply destruction, reserves buy time but cannot provide a solution, because the solution — reopening Hormuz — requires a military outcome or a diplomatic breakthrough that the reserves themselves cannot produce.

This is not a theoretical distinction. The practical consequence is that the 400-million-barrel release suppresses prices for a period of weeks, creating a false sense of adequacy, before the depletion curve catches up and prices resume their climb. Analysis of futures market pricing, published by Goldman Sachs on March 14, shows that Brent crude forward contracts for June 2026 delivery are trading at $118 per barrel — a clear signal that the market does not believe the reserve release will hold prices below $100 for more than six to eight weeks.

What Happens to Countries Without Strategic Reserves?

The IEA system covers 32 member countries, mostly wealthy OECD nations. It does not cover China, India, Indonesia, Pakistan, or most of the developing world. These countries consume approximately 35 million barrels of oil per day combined — roughly one-third of global demand — and many are acutely dependent on Gulf imports.

China maintains its own strategic petroleum reserve, estimated at approximately 950 million barrels across nine surface tank farms and underground storage facilities, according to analysis by the Oxford Institute for Energy Studies published in January 2026. But China is also Iran’s largest remaining oil customer, importing approximately 1.5 million barrels per day of Iranian crude — roughly 80% of Iran’s total exports — through a complex network of ship-to-ship transfers, opaque trading intermediaries, and discounted pricing. The war has disrupted this trade: Iranian crude exports have fallen by approximately 60% since February 28, according to tanker tracking data from Kpler.

India, the world’s third-largest oil consumer at 5.5 million barrels per day, holds a strategic reserve of approximately 39 million barrels — enough for just over seven days of total consumption. The Indian government has been building additional storage at Mangalore, Visakhapatnam, and Padur, but the total capacity remains far below the IEA’s 90-day standard that India, as a non-member, is not required to meet. With 74% of Indian oil imports flowing through Hormuz, the supply disruption has hit India with particular severity.

Pakistan, which imports approximately 450,000 barrels per day with minimal strategic reserves, faces an even more acute crisis. Indonesian reserves cover approximately 25 days of consumption. Bangladesh has less than two weeks. For these countries, the IEA’s 400-million-barrel release is someone else’s insurance policy — drawn from stockpiles they do not hold, benefiting refineries they do not own, at prices they increasingly cannot afford.

The $90 Floor and the $130 Ceiling

Oil prices have established a new trading range since the war began: Brent crude between $90 and $110 per barrel, with WTI tracking $5-8 lower. The IEA reserve release pushed prices from $108 to $97 within 48 hours of the March 11 announcement, a $11 decline that briefly suggested the reserves were working as intended. By March 15, Brent had climbed back above $100.

The price trajectory over the next 50 days depends on three variables: the pace of reserve drawdowns, the probability of a ceasefire, and the behaviour of non-Hormuz producers. On the first variable, the slow ramp-up of releases — particularly the 13-day lag before U.S. SPR barrels reach the market — means that the full 5-to-5.5-million-barrel-per-day drawdown rate will not be achieved until early April. On the second, President Trump has suggested operations could last another three to four weeks, and Iran has publicly rejected ceasefire negotiations. On the third, non-Hormuz producers including the United States (shale), Brazil (pre-salt deepwater), Guyana, Canada (oil sands), Norway, and West African producers are collectively estimated to hold approximately 1.5 to 2 million barrels per day of uncommitted spare capacity, according to Rystad Energy.

Goldman Sachs, JPMorgan, and Morgan Stanley have all revised their Brent crude forecasts upward since the IEA announcement. Goldman’s March 14 note projects Brent averaging $115 per barrel in the second quarter of 2026 if Hormuz remains closed, rising to $130 if the IEA reserve drawdown is exhausted before the Strait reopens. Morgan Stanley’s scenario analysis, published the same day, models a $140-per-barrel spike if Asian reserves deplete before a ceasefire, triggering panic buying in spot markets. Goldman’s analysis extends beyond crude prices to macroeconomic devastation: seventeen days of war have already cost Gulf economies more than Covid did, with Qatar and Kuwait each facing 14 percent GDP contractions that dwarf anything the region has experienced since the 1990s.

For Saudi Arabia, the price floor of $90 is itself transformational. The Kingdom’s fiscal breakeven oil price — the level required to balance the government budget — is approximately $78 per barrel, according to the International Monetary Fund’s Regional Economic Outlook for the Middle East published in October 2025. Every dollar above breakeven generates approximately $3.3 billion in additional annual revenue for the Saudi treasury. At $100 per barrel, the war is generating a revenue premium of $72.6 billion per year compared to pre-war prices — more than enough to fund the Kingdom’s defence expenditures and maintain its Vision 2030 investment programme simultaneously.

After Fifty Days

The strategic reserve system operates on an implicit assumption: the disruption will end before the reserves do. In every previous crisis, that assumption held. This time, there is no guarantee. If Hormuz remains closed beyond early May and strategic reserves approach exhaustion, the global oil market enters territory without historical precedent since the 1973 Arab embargo — and the structural conditions are arguably worse today than they were then.

In 1973, the disruption was voluntary: Arab producers chose to embargo Western buyers, and they could choose to resume supplies at any time. The Hormuz closure is involuntary from the perspective of the countries that need the Strait open: it is maintained by Iranian military force and will persist until that force is neutralised or Tehran agrees to stand down. Neither outcome is imminent.

If the reserves deplete, several cascading consequences follow with near certainty. First, oil prices spike beyond $130 per barrel as the market prices in the total loss of the reserve cushion. Second, consuming nations impose rationing — fuel allocation systems, driving restrictions, industrial energy quotas — that have not been used in OECD countries since the 1970s. Third, the diplomatic pressure on the United States and Israel to negotiate a ceasefire intensifies dramatically, because the economic cost of continuing the war becomes politically unbearable for allies whose economies are being destroyed by energy scarcity.

Saudi Arabia, paradoxically, emerges from this scenario with enhanced rather than diminished power. A world that has exhausted its emergency oil reserves is a world that is fundamentally dependent on whoever can still produce and deliver crude. With its Red Sea export route intact, its production capacity undiminished, and its fiscal position strengthened by three months of $100-plus oil prices, the Kingdom would hold the kind of energy leverage it has not possessed since the 1970s. Mohammed bin Salman’s decision to stay out of direct combat while positioning Saudi Arabia as the indispensable energy supplier may prove to be the most consequential strategic calculation of the war.

The strategic reserve system was built for a world of 60 million barrels per day, fragmented producers, and disruptions measured in weeks. The world now consumes 103 million barrels per day, concentrates one-fifth of supply through a single chokepoint, and faces a disruption with no visible end. The system is not broken. It was never built for this.
Oxford Institute for Energy Studies, March 2026

The 50-day clock started on March 11. It will reach zero sometime in early May. Between now and then, the world’s governments must answer a question that the architects of the IEA never anticipated: what happens when the insurance policy runs out and the house is still on fire?

Frequently Asked Questions

How much oil is in the world’s strategic petroleum reserves?

IEA member countries collectively hold approximately 1.8 billion barrels in strategic reserves, according to IEA data as of March 2026. The United States holds the largest single reserve at approximately 415 million barrels, followed by China’s estimated 950 million barrels (non-IEA), Japan at 175 million barrels, and Germany at 100 million barrels. These reserves represent between 90 and 200 days of net imports depending on the country.

Why did the IEA release 400 million barrels of oil?

The IEA triggered its sixth collective action on March 11, 2026, in response to the closure of the Strait of Hormuz during the Iran war. The closure removed approximately 8 million barrels per day from global supply — the largest disruption in the IEA’s 52-year history. The 400-million-barrel release, contributed by all 32 IEA member countries, aims to stabilise oil markets and prevent prices from spiralling beyond $110-120 per barrel.

How long will the 400 million barrels of emergency oil last?

At the IEA’s estimated supply shortfall of 8 million barrels per day, the 400-million-barrel release provides approximately 50 days of coverage if fully applied against the Hormuz disruption. Realistic global drawdown capacity of 5 to 5.5 million barrels per day extends the release period but also means it covers only a portion of the total shortfall, leaving a gap of 2.5 to 3 million barrels per day that keeps prices elevated.

What is the U.S. Strategic Petroleum Reserve and how full is it?

The U.S. SPR is the world’s largest government-owned emergency oil stockpile, stored in underground salt dome caverns along the Gulf Coast in Texas and Louisiana. It has an authorised capacity of 714 million barrels but held only 415 million barrels — 58% of capacity — when the Iran war began. After the planned 172-million-barrel release, it will hold approximately 243 million barrels, its lowest level since the early 1980s.

Which countries are most vulnerable to the Hormuz closure?

Japan, South Korea, and India are the most vulnerable IEA and non-IEA countries because they import 69% to 85% of their crude oil through the Strait of Hormuz. Japan’s strategic reserves cover approximately 60 days of Hormuz-dependent imports after contributing to the IEA release, while South Korea’s cover approximately 43 days. India, which holds only about seven days of consumption in strategic reserves, faces the most severe shortfall among major economies.

Can Saudi Arabia still export oil with Hormuz closed?

Saudi Arabia maintains the 1,200-kilometre East-West Pipeline connecting its Eastern Province oil fields to the Red Sea port of Yanbu, with a nominal capacity of 5 million barrels per day and an effective throughput of approximately 3.5 million barrels per day. This bypass route allows the Kingdom to continue exporting roughly half its pre-war volume without using the Strait of Hormuz, making Saudi Arabia the only major Gulf producer with a fully operational alternative export route.

Has the IEA ever released this much oil before?

The March 2026 release of 400 million barrels is more than double the previous record of 182.7 million barrels released in 2022 during the Russia-Ukraine war. Prior collective actions were significantly smaller: 17.3 million barrels in 1991 (Gulf War), 30 million in 2005 (Hurricane Katrina), and 30 million in 2011 (Libyan Civil War). The 2026 release is also unprecedented in its coverage ratio — just 50 days against the disruption — compared to 20 to 122 days in previous actions.
