A more severe crisis in the international oil market is imminent—and its duration will exceed expectations.

An imminent oil shortage crisis Impacted by the U.S.-Israel-Iran war, Brent crude futures—though fluctuating—broke above USD 100 per barrel on March 12, 2026, and remain above that level as of now. On May 17, 2026, industry expert Irina Slav published an article titled “Oil Price” warning that a far more severe oil shortage crisis is imminent. Slav pointed out that the global oil market is rapidly tightening: the blockade of the Strait of Hormuz has already disrupted hundreds of millions of barrels of oil supply; by month-end, losses may reach one billion barrels. The International Energy Agency (IEA) currently forecasts a sharp global oil supply decline in 2026, while demand remains relatively resilient—raising concerns that inventories could soon reach critically stressed levels. Analysts and industry leaders warn that strategic reserves are being depleted faster than anticipated, meaning this crisis could escalate from crude oil shortages into a full-blown global fuel and refining crisis—if the Strait of Hormuz is not reopened promptly. The notion that the world’s oil is about to run out seemed implausible just three months ago—but with the Strait of Hormuz nearly completely blocked, widespread crude shortages are becoming an increasingly tangible reality. Analysts no longer anticipate a swift end to the war among the U.S., Israel, and Iran; instead, they now contemplate prolonged, severe disruptions to energy flows—and the outlook appears deeply pessimistic. Kpler reported earlier this month that, as of May 8, cumulative oil supply losses from the Middle East since February 28 have reached 782 million barrels—and are expected to expand to one billion barrels by month-end. Daily production losses are equally alarming: Saudi Arabia is losing over 3 million barrels per day (bpd); Iraq, 2.88 million bpd; Iran, 1.69 million bpd; and Kuwait, 1.75 million bpd. Given such massive output cuts, drawing down reserves is the most rational response. Prior to the outbreak of war, the IEA had forecast global oil inventories would reach record highs—a key reason behind predictions of severe oversupply, possibly reaching nearly 4 million bpd. Now, however, the IEA warns that global oil demand will exceed supply this year. In its latest monthly report, the IEA estimates global oil supply will decline by approximately 3.9 million bpd this year—a figure far below the actual current supply shortfall in the Middle East. The IEA estimates the Middle East’s supply gap at 10.5 million bpd. Yet even though supply is projected to fall by 3.9 million bpd (perhaps an optimistic estimate), demand is expected to drop by only 420,000 bpd, according to data from this authoritative energy institution. “You can only cut consumption so much—once inventories are gone, they’re truly gone,” Ellen Wald, Senior Fellow at the Atlantic Council’s Global Energy Center, told The Wall Street Journal this week. “At a certain point, markets will clash—and prices will surge.” This echoes a warning issued earlier this month by the CEO of Saudi Aramco, who stated that global onshore fuel inventories are depleting at a record pace.

IEA warns: Q3 crude supply deficit expectation doubled; annual deficit may hit five-year high.

Renewed Middle East hostilities are accelerating disruption to global oil supply. Although high oil prices have clearly dampened demand, supply-side contractions still vastly exceed demand reductions—causing global oil inventories to deplete at an accelerated pace. The International Energy Agency (IEA)’s latest monthly report shows that, due to renewed conflict in the Middle East and maritime transport disruptions, the global oil market currently faces a supply deficit of approximately 1.8 million barrels per day (bpd). The IEA has doubled its forecast for the Q3 supply deficit and now expects the full-year 2026 deficit to reach the highest level in five years. Since the outbreak of hostilities, global oil inventories have declined by 410 million barrels—69 million barrels alone in July. Meanwhile, the IEA has raised its 2026 global oil demand reduction forecast by 510,000 bpd—to 1.6 million bpd—meaning global oil demand this year will post its largest annual decline since 2020. Yet even with demand suppressed by high prices, supply losses continue to exert sustained pressure on inventories. 8.3 million bpd of capacity remains offline in the Persian Gulf According to IEA data, global oil supply rose by 2.4 million bpd month-on-month in July—but remains 6.3 million bpd lower than the same period last year. Approximately 8.3 million bpd of oil production capacity in the Persian Gulf remains offline, and ongoing maritime transport disruptions continue to hinder supply recovery. Among major producers: Saudi Arabia increased its oil supply by 900,000 bpd to 8.2 million bpd in July; Iraq increased by 470,000 bpd to 2.9 million bpd; Iran increased by 330,000 bpd to 2.6 million bpd; and Kuwait increased by 290,000 bpd to 1.8 million bpd. In contrast, the UAE’s output fell to 3.9 million bpd amid regional shipping attacks. U.S. Energy Secretary Chris Wright stated on Tuesday that roughly 9 million bpd of oil were successfully shipped abroad over the past week—about half the pre-war level. Saudi Arabia and the UAE have diverted exports via alternative pipelines, while a tanker relay network has formed in the Strait of Hormuz—partially mitigating the impact of normal shipping disruptions.

IEA: Global Oil Supply and Demand Cuts Projected to Exceed Expectations

Sep 16, 2026

The IEA projects global oil supply and demand cuts will exceed prior forecasts, citing Middle East conflicts delaying supply recovery until 2027. Record inventory drawdowns and soaring fuel prices indicate severe market tightness.
