Analysts call Hormuz largest oil supply disruption

The International Energy Agency said on March 20 that the war in the Middle East had triggered “the largest supply disruption in the history of the global oil market,” with shipping through the Strait of Hormuz severely constrained. The agency said the disruption had strained diesel, jet fuel and LPG markets and prompted it to publish demand-side measures for governments, businesses and households. On May 21, social-media commentary amplified those warnings, tying the supply shock to inflation, jobs, food prices and broader supply chains. The core facts behind that commentary are already on the record: the IEA says Hormuz is a critical artery for oil and gas exports, and QatarEnergy says attacks on Ras Laffan damaged LNG capacity and forced production stoppages. ### Why are analysts calling Hormuz the biggest oil supply shock on record? The IEA said on March 20 that the conflict had caused the largest supply disruption in the history of the global oil market. In a separate May 2026 oil market report, the agency said mounting losses from the Strait of Hormuz were depleting global oil inventories at a record pace and sending benchmark prices through sharp swings. The Strait of Hormuz is the primary export route for oil produced by Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Iraq, Bahrain and Iran, according to the IEA. The agency says a prolonged disruption would not only block shipments from those producers but also render unavailable most of the world’s spare production capacity, much of it held by Saudi Arabia. ### How much of the world’s energy trade runs through Hormuz? The IEA says the waterway is central to both crude and LNG flows from the Gulf. Its country-reliance tool, highlighted again on May 21, shows which economies depend most heavily on Middle Eastern oil and gas imports and how that dependence changed between 2017 and 2024. The IEA’s maritime chokepoints monitor, last updated May 12, tracks shipping through three Middle East corridors and says it will continue to update flows as the conflict evolves. That gives governments and traders a live measure of how much oil, gas and other cargo is still moving. ### What happened at Ras Laffan, and why does it matter for LNG? QatarEnergy said on March 2 that it had ceased production of LNG and associated products after military attacks on operating facilities in Ras Laffan Industrial City and Mesaieed Industrial City. On March 19, the company said missile strikes on Ras Laffan had reduced LNG export capacity by 17%, would cost about $20 billion a year in lost revenue and could take up to five years to repair. Saad Sherida Al-Kaabi, Qatar’s energy minister and QatarEnergy chief executive, said the damage would affect supply to markets in Europe and Asia. DLA Piper said in an April note that the combination of Ras Laffan disruption and the effective closure of Hormuz had pushed the LNG market into “unprecedented territory,” with force majeure declared on significant portions of long-term contracts. ### Why are inflation and stagflation showing up in the commentary? The IEA said on March 20 that it was proposing ways to ease price pressure on consumers because the disruption was already feeding through fuel markets. Its recommendations covered road transport, air travel, cooking and industry, underscoring that the shock was not limited to crude prices alone. S&P Global said the conflict had temporarily disrupted roughly one-fifth of global LNG supply and sharply tightened near-term market balances. It said Asia-Pacific markets were bearing the brunt because of their reliance on Qatari and UAE LNG, while Europe was adjusting through price signals and cargo diversions. ### What should readers watch next? The IEA said it continues to monitor the Middle East situation through its energy-markets hub, oil market reports and shipping monitor. QatarEnergy’s next formal updates on Ras Laffan repairs, LNG capacity and contract performance will be the clearest company-specific markers for whether the disruption is easing or deepening.
