The warning sent by Airports Council International (ACI) Europe to the European Commission on April 10, 2026, was not merely a cry for help. It was a formal notification of a systemic failure decades in the making. Within three weeks, the continent faces a reality where the simple act of fueling a commercial aircraft may become a logistical impossibility at several major hubs.
While the immediate catalyst is the closure of the Strait of Hormuz following the escalation of regional conflict in late February, the crisis is not a "black swan" event. It is the inevitable result of a deliberate, decade-long dismantling of European refining capacity in favor of a "just-in-time" import model that has now collided with geopolitical reality. Europe is no longer just energy-dependent; it is operationally fragile.
The Import Trap and the Death of the European Refinery
For years, European policymakers and oil majors operated under the assumption that the Middle East and India would serve as the continent's permanent "external" refineries. As environmental regulations tightened and profit margins on fossil fuels thinned, Europe shuttered or converted its refining assets at an aggressive pace. Since 2020, primary refining capacity across the EU and the UK has steadily eroded, leaving the region reliant on the Persian Gulf for roughly 30% of its jet fuel.
This strategy worked in a world of frictionless maritime trade. It fails spectacularly when the primary artery for that trade—a passage carrying 15 million barrels of crude and 5 million barrels of refined products daily—is severed.
The math for Europe's airports is now brutal. Jet fuel reserves at the Antwerp-Rotterdam-Amsterdam (ARA) hub, the heart of the continent’s distribution network, are depleting faster than they can be replenished by redirected Atlantic shipments. Italian airports have already begun rationing, a move that is less about current scarcity and more about a desperate attempt to avoid "tank dry" scenarios before the peak summer season.
The SAF Mirage and the Regulatory Squeeze
Compounding the physical shortage is a regulatory framework that was designed for a transition, not a crisis. The ReFuelEU Aviation mandate, which kicked in during 2025, requires a 2% blend of Sustainable Aviation Fuel (SAF). On paper, this is a cornerstone of the "Fit for 55" climate package. In practice, during a supply crunch, it acts as a massive friction point.
SAF production in 2026 is projected to hit only 2.4 million tonnes, a downward revision from previous years due to stalled investment and feedstock bottlenecks. Airlines are now paying up to five times the price of conventional kerosene for SAF just to meet legal quotas, even as the base price of fossil-based jet fuel has doubled to over $1,600 per tonne.
The industry is caught in a pincer movement. On one side, the physical supply of kerosene is restricted by the Hormuz blockade. On the other, the legal mandate to blend scarce SAF remains inflexible. This creates an "oligopolistic" supply chain where the few providers with available stock can dictate terms that threaten the solvency of mid-tier carriers.
The Invisible Infrastructure Bottleneck
Even if tankers were to miraculously appear at European ports tomorrow, the internal distribution system is ill-equipped for a rapid pivot. Europe’s jet fuel supply relies on aging hydrant systems and a network of pipelines that were optimized for specific flow directions—mostly from coastal refineries to inland hubs.
Shifting the entire supply chain to favor imports from the United States or West Africa requires more than just different shipping routes. It requires a reconfiguration of storage logistics that cannot happen in three weeks.
- Refinery maintenance: European refiners are currently in their spring maintenance cycle. Despite the price spikes, many are refusing to delay this work, fearing that pushing aging equipment harder could lead to catastrophic mechanical failures.
- The "Tankering" Ban: EU rules strictly prohibit "fuel tankering"—the practice of carrying extra fuel from cheaper, outside regions to avoid refueling at expensive airports—to minimize carbon emissions from the extra weight. In a shortage, this rule prevents airlines from bringing their own "safety net" into the bloc.
The Economic Aftershock
The era of the $50 intra-European flight is effectively over. If the Strait of Hormuz remains closed or restricted into May, the industry is looking at more than just higher surcharges. We are looking at "connectivity pruning."
Airlines will prioritize high-yield, long-haul routes where the fuel-to-profit ratio is most favorable, leaving regional and secondary airports in the lurch. This isn't just a headache for vacationers; it is a structural blow to the tourism-dependent economies of Southern Europe that rely on a constant, high-volume flow of air traffic.
The IMF has already signaled that there will be "no neat and clean return to the status quo." Even if a stable ceasefire is maintained, the risk premium on jet fuel is unlikely to evaporate. The "scarring effects" mentioned by Kristalina Georgieva refer to a permanent shift in how energy security is priced into the cost of doing business in Europe.
Governments are now scrambling to create "EU-wide monitoring" of jet fuel production, a tool that ACI Europe points out does not currently exist. The fact that the European Union does not have a real-time map of its own jet fuel availability in 2026 is an indictment of the complacency that defined the last decade of energy policy.
The solution is not as simple as reopening a strait or signing a new supply contract. It requires a fundamental re-evaluation of whether a continent can afford to outsource its most critical transport fuel while simultaneously mandating a transition to a "sustainable" alternative that doesn't yet exist at scale. Without a strategic reserve or a revival of domestic refining capacity, the European aviation sector remains one geopolitical tremor away from a permanent grounding.
Stop looking for a "return to normal." The current shortage is the new baseline.
