IEA warns Hormuz crisis could push markets 'red zone'

The International Energy Agency said a prolonged disruption in the Strait of Hormuz could push global oil markets into a “red zone” within months as emergency reserves are drawn down and summer demand rises. The warning, cited in reports on May 24, came as the waterway’s disruption stretched into a fourth month and governments continued to rely on strategic stock releases to cushion lost supply. Fatih Birol, the IEA’s executive director, said the risk period could arrive in July or August if flows do not recover and tanker traffic remains heavily restricted. The Strait is one of the world’s main energy chokepoints, and the IEA says any prolonged disruption there also sidelines much of the world’s spare production capacity. ### Why is the IEA talking about a “red zone” now? Fatih Birol said the market could enter a “red zone” by July or August if supplies fail to recover and inventories continue to fall, according to reporting that cited the IEA chief on May 24. The agency’s own Middle East energy page says resuming flows through the Strait of Hormuz is “the single most important variable” for easing pressure on supplies, prices and the global economy. (gulfnews.com) The IEA said member countries launched their largest-ever coordinated oil stock release after the conflict that began on Feb. 28, 2026 impeded flows through Hormuz. That release was designed to offset a sharp loss of crude and product exports from the Gulf, but the agency has also said emergency inventories cannot substitute indefinitely for normal transit through the strait.

The agency said that volume represented around 25% of the world’s seaborne oil trade, while U.S. Energy Information Administration data described the strait as a chokepoint through which nearly 20% of global oil supply flowed before the latest conflict. (iea.org) The IEA’s Strait of Hormuz page says the route is the primary export corridor for oil produced by Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Iraq, Bahrain and Iran. It says a prolonged disruption would not only curb shipments from those states but also make unavailable most of the world’s spare production capacity, much of it held by Saudi Arabia.

The IEA said observed global inventories, including oil on water, fell by 250 million barrels over March and April, equivalent to 4 million barrels a day. The agency said those draws were underpinned by the historic stock release announced in March and by the continuing strain on Gulf exports. The U.S. (iea.org) Energy Information Administration said on May 12 that global oil markets were in a period of heightened volatility and uncertainty because of the de facto closure of Hormuz. Its outlook said Brent crude oil prices had risen as the disruption cut available supply and increased uncertainty around future flows. ### Have any shipments started moving again? (iea.org) Reuters reported on May 20 that three supertankers crossed the Strait of Hormuz carrying 6 million barrels of Middle East crude bound for Asian markets after waiting in the Gulf for more than two months. The movement showed some cargoes were getting through, but it did not amount to a return to normal shipping volumes. (eia.gov) The IEA said in March that export volumes of crude and refined products were running at less than 10% of pre-conflict levels. Its later updates continued to describe Hormuz as the central variable for market stabilization, suggesting that isolated sailings have not resolved the broader supply problem.

The U.S. Energy Information Administration has said its next Short-Term Energy Outlook is due on June 9, and the IEA’s Strait of Hormuz and energy crisis tracker pages continue to post updates on flows, stock releases and policy responses.
