On the morning of March 3, 2026, three days after fighting broke out across the Persian Gulf, a London-based tanker broker told clients on a conference call that his firm could not quote a rate for a single vessel willing to transit the Strait of Hormuz. “There is no price,” he said. “The market is closed.” Within weeks, the narrow waterway that had carried more than 20 million barrels of crude and refined products every day before the conflict was moving fewer than 4 million. The International Energy Agency’s May 2026 Oil Market Report puts total shut-in supply at more than 14 million barrels per day, a figure that dwarfs every previous disruption on record. Brent crude, which sat near $78 a barrel in late February, has since surged past $140.
For drivers filling up at the pump, airlines repricing summer schedules, and governments scrambling to prevent a full-blown recession, the math is brutal: more than one in every ten barrels the world was consuming before the war is no longer available, and the emergency reserves being burned through to fill the gap will take years to rebuild.
The scale of what’s been lost
Two independent government agencies have tried to measure the damage. Their methodologies differ, but their conclusions converge: nothing like this has happened before.
The IEA’s 14 mb/d estimate captures gross Gulf production losses, including barrels that producers could theoretically pump but cannot ship because of blocked sea lanes, damaged export terminals, or insurance restrictions that have made certain routes commercially unviable. The U.S. Energy Information Administration, using its own modeling in the Short-Term Energy Outlook released May 12, 2026, estimates that forced shut-ins tied directly to conflict damage, sanctions enforcement, and operational outages averaged roughly 10.5 mb/d in April and could peak near 10.8 mb/d in May. The gap between the two numbers largely reflects barrels that are physically intact but commercially stranded.
The historical comparisons make the scale plain. The 1990 Iraqi invasion of Kuwait removed about 4.3 million barrels per day from the market. The 2011 Libyan civil war took out roughly 1.5 million. Even the broad disruption to Russian flows after the 2022 invasion of Ukraine, which reshaped global trade routes over many months, never exceeded 2 million barrels per day of net lost supply, according to IEA tracking at the time. The current shock is three to four times larger than any of them.
Observed global inventories fell by 250 million barrels over March and April alone, a draw rate of roughly 4 million barrels per day, based on the IEA’s assessment of OECD commercial stocks and floating storage data. That metric does not capture non-OECD inventory changes, which are reported with longer delays and less transparency, meaning the true global draw could be larger. At that pace, the world is consuming its visible cushion faster than at any point since modern inventory tracking began in the 1980s.
Workarounds are helping, but not nearly enough
Some oil is still getting out. Diversions through alternative corridors, including the Iraq-to-Ceyhan pipeline through Turkey, Saudi Arabia’s Red Sea terminals fed by the East-West Pipeline, and loadings from the Emirati port of Fujairah on the Gulf of Oman, have pushed rerouted volumes to roughly 7.2 mb/d, according to IEA tanker and pipeline monitoring from April 2026. That is a significant logistical achievement, but it replaces only about a third of lost Hormuz throughput.
The bottleneck is physical. Pipelines have fixed capacity. Red Sea terminals were never designed to handle the full export load of the Gulf’s largest producers simultaneously. War-risk insurance premiums have climbed so steeply that some shipowners are refusing to send tankers anywhere near the conflict zone, even on routes that remain technically open.
OPEC+ has pledged to accelerate the unwinding of its voluntary production cuts, but the promise rings hollow when the producers with the most spare capacity, Saudi Arabia and the UAE, cannot get additional barrels to market through a chokepoint that is functionally closed. Non-Gulf OPEC members such as Nigeria and Angola have limited room to ramp up, and U.S. shale producers, while increasing rig counts, cannot meaningfully boost output for months.
The biggest emergency stock release ever attempted
Governments moved fast. IEA member countries unanimously agreed to mobilize 400 million barrels from strategic reserves, the largest coordinated drawdown in the agency’s 50-year history. The previous record was the 2022 release of roughly 182 million barrels in response to the Russia-Ukraine war.
Total emergency stockpiles across IEA nations stand at over 1.2 billion barrels of government-held reserves plus about 600 million barrels of obligated industry holdings. That sounds like a deep buffer. At a sustained draw of 4 million barrels per day, however, the 400 million barrel pledge covers only about three months of shortfall.
The United States is shouldering the largest single-country share. Washington authorized the release of 172 million barrels from the Strategic Petroleum Reserve, according to the Department of Energy. (For reference, the DOE’s 2022 authorization to release barrels from the SPR is documented on its website; the 2026 drawdown follows the same legal framework but at a larger scale.) By the end of April, roughly 17.5 million barrels had left storage caverns along the Gulf Coast, with deliveries expected to accelerate through the summer. The SPR, which held about 400 million barrels before the latest authorization, had already been drawn down significantly during the 2022 release and was never fully replenished. After this round, it will sit near 228 million barrels, its lowest level since 1983.
What no one can measure yet
The gap between the IEA and EIA disruption estimates points to a deeper problem: real-time visibility into Gulf oil flows has broken down. The IEA’s chokepoint shipping monitor, built on the IMF PortWatch platform, relies on Automatic Identification System signals from tankers. In a conflict zone, those signals are unreliable. Ships go dark, spoof their positions, or switch off transponders entirely. The IEA has flagged these limitations openly, and no independent maritime authority has published verified transit counts that fully reconcile the two agencies’ numbers.
Gulf producers have added little clarity. Saudi Arabia, the United Arab Emirates, Kuwait, and Iraq have all issued statements affirming their intent to restore exports “as soon as security conditions allow,” but none has provided a detailed timeline for reopening damaged terminals or repairing offshore loading infrastructure. Satellite imagery reviewed by commercial analytics firms shows visible damage at several key facilities, though the extent remains disputed.
On the demand side, the picture is equally murky. High-frequency indicators, including mobility data, refinery run rates in Asia and Europe, and airline schedule filings, suggest that consumption is beginning to soften under the weight of triple-digit oil prices. But official demand statistics lag by weeks or months, and policy responses are still evolving. Several European governments have introduced fuel tax holidays. India has expanded subsidies. China has reportedly begun drawing on its own commercial reserves, though Beijing has not confirmed volumes.
Liquefied natural gas adds another layer of uncertainty. The Strait of Hormuz carried roughly 20 percent of global LNG trade before the conflict, primarily Qatari cargoes bound for Asia and Europe. Those flows have been severely curtailed, pushing Asian spot LNG prices above $30 per million BTU and raising the prospect of gas shortages heading into the Northern Hemisphere’s next heating season.
Three months of breathing room, then a reckoning
At current release rates, the 400 million barrels pledged by IEA members buy roughly three months of cover. If Hormuz traffic does not recover meaningfully by late summer, governments will face a stark choice: authorize a second round of releases from reserves that are already at historic lows, or accept sustained prices well above $100 a barrel and the recession risks that come with them.
Rebuilding the reserves themselves will be a multiyear project. After the comparatively modest 2022 SPR drawdown, the U.S. government spent more than two years buying back barrels, and the reserve never returned to its pre-release level. A drawdown nearly twice that size, into a market where spare production capacity outside the Gulf is thin, will be far harder and more expensive to reverse.
The risk that policymakers are most worried about, according to officials briefed on IEA discussions, is a timing mismatch: overestimating how quickly high prices destroy demand, overdraining strategic stocks now, and then facing a second supply shock if the conflict escalates or spreads. The tools available to governments are finite, and every week the fighting continues, the global cushion gets thinner.
