IEA Chief Warns Europe Has “Maybe 6 Weeks of Jet Fuel Left,” Calls Iran War Blockade “Largest Energy Crisis We Have Ever Faced”

International Energy Agency Executive Director Fatih Birol warned in an exclusive interview with the Associated Press on April 16, 2026 that Europe has "maybe six weeks or so of jet fuel left" and that flight cancellations could begin "soon" if oil supplies blocked by the Iran war are not restored. Birol described the current situation as "the largest energy crisis we have ever faced," driven entirely by the closure of the Strait of Hormuz and the disruption of oil, gas, and other vital commodity flows through the 21-nautical-mile-wide chokepoint.

"In the past there was a group called 'Dire Straits.' It's a dire strait now, and it is going to have major implications for the global economy," Birol told AP from IEA headquarters in Paris. He warned that without a settlement of the Iran war that permanently reopens the strait, "everybody is going to suffer," adding that "no country, no country is immune to this crisis." He noted the human cost would fall disproportionately on developing nations: "The countries who will suffer the most will not be those whose voice are heard a lot. It will be mainly the developing countries. Poorer countries in Asia, in Africa and in Latin America."

The jet fuel warning has direct implications for U.S. aviation infrastructure. The United States is the world's largest aviation market and is deeply integrated with European carriers and global aviation supply chains. Jet fuel is a refined petroleum product derived from kerosene-range distillates; European refineries have historically sourced significant volumes of crude feedstock from Gulf producers who transit through the Strait of Hormuz. A six-week supply horizon — running out approximately late May 2026 if the blockade continues — means European airline cancellations could begin affecting transatlantic routes, American airports, and the broader U.S. aviation infrastructure within weeks.

The IEA has released 400 million barrels of strategic petroleum reserves as part of a coordinated 32-nation response, but Birol's warning signals that those emergency releases are insufficient to bridge an extended closure. Brent crude was trading above $96 per barrel as of this week, down from a peak above $118 but still approximately 30-40 percent above pre-war levels. The IEA warned that not reopening the waterway within weeks could compound repercussions for global energy supplies that are already severely strained.
