Europe could be heading toward a major aviation and economic disruption, with just about six weeks of jet fuel supply remaining if the ongoing conflict involving Iran continues to block critical energy routes, according to the head of the International Energy Agency.
The warning, issued by IEA Executive Director Fatih Birol, highlights the growing severity of the crisis triggered by the closure of the Strait of Hormuz, one of the most important energy corridors in the world. Nearly 20 percent of global oil and gas trade passes through this narrow waterway, making any disruption immediately felt across international markets.
Birol warned that Europe has “maybe six weeks or so of jet fuel left,” cautioning that if supplies remain blocked, flight cancellations could begin soon. His remarks underline what he described as “the largest energy crisis we have ever faced,” with consequences extending far beyond aviation.
Already, early signs of strain are emerging across Europe’s airline industry. Some carriers have begun cutting routes or reducing flight capacity, not necessarily due to immediate shortages, but because soaring fuel costs are making certain routes financially unsustainable. In one example, airlines have trimmed hundreds of flights in anticipation of worsening conditions, even as they insist that physical fuel shortages have not yet fully materialised.
The situation is particularly concerning because Europe relies heavily on imported jet fuel and refined petroleum products from the Middle East. With tanker traffic through the Strait of Hormuz effectively halted due to the conflict, supply chains have been severely disrupted. The last shipments that left before the blockade are still being used, but once those reserves are exhausted, the continent could face real shortages.
Industry bodies have already raised alarms. The Airports Council International Europe warned that shortages could begin as early as May if shipments do not resume, placing pressure on airlines during the peak summer travel season.
Beyond aviation, the crisis is expected to have wider economic consequences. Rising fuel prices are already pushing up the cost of transport, logistics, and manufacturing, which in turn feeds into inflation. Birol noted that the impact would include “higher gasoline prices, higher gas prices, high electricity prices,” affecting both businesses and consumers globally.
The ripple effects could be particularly severe for developing economies, but Europe is not immune. Analysts warn that prolonged disruption could slow economic growth or even trigger recessionary pressures, especially in energy-dependent industries.
Despite the stark warnings, officials and industry leaders are urging caution against panic. Some airlines and suppliers have emphasised that, for now, there is no immediate physical shortage of jet fuel, and contingency measures are being explored. These include adjusting flight schedules, sourcing alternative supplies, and relying on strategic reserves where available.
However, the margin for error is shrinking. The longer the Strait of Hormuz remains closed, the more difficult it becomes to stabilise supply chains. Unlike other disruptions that can be offset by rerouting shipments, the scale of energy flow through this route makes it extremely difficult to replace in the short term.
The geopolitical backdrop adds another layer of uncertainty. The conflict, which escalated following military actions involving the United States and its allies, has led to heightened tensions and limited diplomatic progress. While there have been suggestions that talks could resume, no clear resolution is in sight.
For Europe, the stakes are high. The aviation sector is a critical component of the economy, supporting tourism, trade, and connectivity. A sustained jet fuel shortage would not only disrupt travel but also affect supply chains, business operations, and consumer confidence.
The situation ultimately exposes the fragility of global energy systems. A single chokepoint, thousands of miles away, now holds the potential to disrupt entire industries across continents. It is a reminder that in an interconnected world, energy security is inseparable from geopolitical stability.
For now, Europe is not out of fuel, but it is on a clock. If the current crisis drags on, the continent could soon face a scenario where grounded flights become the first visible sign of a much deeper economic challenge.
