NextFin News - The European Commission issued a stark warning on Monday that the continent’s aviation sector faces a critical kerosene shortage by June if the Strait of Hormuz remains closed to maritime traffic. With approximately 20% of the world’s oil supply currently trapped behind the blockade, the logistical strain on European refineries has reached a tipping point, forcing airlines to weigh immediate flight cancellations against the reality of dwindling strategic reserves.
The alert from Brussels follows a series of increasingly urgent assessments from industry bodies. Last week, the Airports Council International Europe (ACI Europe) notified the European Commission that localized fuel shortages could manifest as early as the first week of May. While the Commission maintains that there is no widespread physical shortage at the pump today, the economic impact is already visible. Brent crude prices have surged to $101.84 per barrel, a level that has triggered a wave of "preemptive" cancellations by carriers struggling to absorb the doubling of jet fuel costs since the onset of the regional conflict.
Fatih Birol, Executive Director of the International Energy Agency (IEA), stated on Thursday that Europe has "maybe six weeks or so of jet fuel left" in its current inventory. Birol, who has led the IEA since 2015 and is known for his pragmatic, data-driven approach to energy security, warned that the transition from high prices to physical unavailability is imminent. His assessment suggests that without a diplomatic breakthrough to reopen the Strait, the narrative of the European travel market will shift from "expensive" to "grounded" before the peak summer season begins.
This perspective, while authoritative, is not yet a consensus view across all market participants. Some analysts at major European energy desks argue that the IEA’s six-week timeline represents a worst-case scenario that discounts the potential for redirected supplies from North America or increased rail-bound imports from Central Asia. These skeptics suggest that while the Strait of Hormuz is a vital artery, the global refining system possesses enough latent flexibility to prevent a total collapse of European flight schedules, provided that demand is sufficiently dampened by high ticket prices.
The immediate burden is falling on major carriers such as Lufthansa, Air France-KLM, and Ryanair. Airlines for Europe (A4E), a trade association representing these giants, has intensified its lobbying efforts, demanding that the European Union provide real-time transparency on fuel stocks at individual airport hubs. The lack of granular data has created a "fog of war" in flight planning, where airlines are unsure if a long-haul jet landing in Frankfurt or Paris will find enough kerosene for its return leg.
The crisis is particularly acute because Europe’s refining capacity for middle distillates—the category of oil that includes jet fuel and diesel—has been structurally weakened over the last decade. Many European refineries were shuttered or converted to biofuels during the pandemic, leaving the continent heavily reliant on imports from the Middle East. The closure of the Strait of Hormuz has effectively severed this umbilical cord, exposing a strategic vulnerability that cannot be solved by simply paying higher prices for the remaining global supply.
Market data indicates that jet fuel prices in Belgium and the UK have climbed toward $2.15 per gallon, nearly double the historical averages seen in early 2025. This price spike has already led to a 15% reduction in planned capacity for some regional routes, as low-cost carriers find it impossible to maintain profitability. If the blockade persists into June, the European Commission’s warning implies that the industry will move beyond voluntary capacity cuts into a phase of mandatory rationing, potentially prioritizing essential cargo and medical flights over leisure travel.
