The International Energy Agency has significantly downgraded its global oil market outlook for 2026, citing the Iran war as a major catalyst for both supply and demand contractions. According to the IEA's monthly oil market report released in April 2026, the agency now predicts an 80,000 barrels per day drop in demand growth this year, a dramatic reversal from the 640,000 bpd rise forecasted in its March report. The conflict has fundamentally altered the global energy landscape.
The IEA stated that the Iran war has thoroughly upended the global outlook for oil consumption, with demand weakness expected to deepen as scarcity and higher prices persist. The deepest cuts in oil consumption have emerged from the Middle East and Asia-Pacific regions, particularly affecting naphtha, liquefied petroleum gas, and jet fuel demand. On the supply side, the situation is equally severe.
Global oil output is expected to fall by 1.5 million barrels per day on average in 2026 compared to the previous year. This represents an approximate 2.6 million bpd swing from the IEA's March forecast, which had predicted a 1.1 million bpd rise in supply. Strikes on Middle East energy infrastructure and Iran's effective closure of the Strait of Hormuz have devastated production and export capabilities.
The IEA reported that attacks on regional energy infrastructure and the closure of the Strait of Hormuz resulted in a loss of 10.1 million barrels per day of supply in March 2026, which the agency characterized as the largest oil supply disruption in history. The flow of crude oil, refined fuels and natural gas liquids through the Strait of Hormuz had plummeted to just 3.8 million bpd in early April, down from more than 20 million bpd in February before initial strikes on Iran. The projected 1.5 million bpd drop in demand in the second quarter of 2026 would mark the deepest contraction since the COVID-19 pandemic, according to the IEA.
The agency forecasts that supply will be higher than demand by only 410,000 barrels per day in 2026, a substantial reduction from the 2.46 million bpd surplus predicted in the previous month's report. Oil prices showed relatively muted reactions to the IEA's downbeat report. Brent crude futures traded at $98.60 per barrel at 0847 GMT on the day of the report release, showing little change from $98.58 per barrel just before the announcement.
The IEA emphasized that reopening the Strait of Hormuz remains the single most important variable for easing pressure on energy supplies, prices and the global economy. In its base case scenario, the IEA forecasts that regular deliveries of oil and gas from the Middle East to international markets will resume by mid-year, although at levels below pre-conflict figures. However, the agency presented a more severe alternative scenario involving longer-term supply disruptions.
Under this scenario, global markets could draw almost 2 billion barrels of oil from strategic reserves and demand could fall 5 million barrels per day year-on-year on average from the second quarter through the fourth quarter. The IEA noted that with the geopolitical situation remaining fluid and prospects for a lasting negotiated settlement still unclear, both scenarios represent the range of probable outcomes. OPEC, the Organization of the Petroleum Exporting Countries, also lowered its own prediction for world oil demand in the second quarter of 2026, though the group maintained its full-year demand outlook unchanged.
