NextFin News - Europe’s aviation sector is facing a critical countdown as jet fuel reserves dwindle to approximately six weeks of supply, threatening widespread flight cancellations across the continent. Fatih Birol, Executive Director of the International Energy Agency (IEA), warned on Thursday that the blockade of the Strait of Hormuz and the ongoing conflict involving Iran have triggered the most severe energy crisis in modern history. According to Birol, the exhaustion of current stockpiles could force airlines to ground fleets "soon" unless alternative supply routes are secured or the waterway is reopened.
The crisis has already sent shockwaves through energy markets. Brent crude is currently trading at 98.01 USD/barrel, while European jet fuel prices have surged by approximately 95% since late February. In Northwest Europe, the price for jet fuel reached a staggering $1,903.50 per ton this week, an all-time high that reflects the structural tightness of a market suddenly deprived of Middle Eastern refined products. Birol, a Turkish economist who has led the IEA since 2015, has historically advocated for aggressive transitions to renewable energy but has recently shifted his focus toward the immediate fragility of global fossil fuel supply chains. His current assessment is particularly grim, suggesting that even a swift diplomatic resolution would not provide an immediate fix, as over one-third of the region’s 80 key energy assets have suffered severe damage.
While the IEA’s warning serves as a "red alert" for the industry, the impact is not being felt uniformly across the European aviation landscape. The crisis has exposed a deep divide in the financial resilience of major carriers. Goldman Sachs recently downgraded Lufthansa to a "sell" rating, projecting a $1 billion loss on the airline’s fuel hedges as the conflict persists. Conversely, some low-cost carriers and larger groups like Air France-KLM and IAG (the parent company of British Airways) had locked in a portion of their fuel needs at lower prices earlier in the year. However, these hedges are rapidly unwinding, and the industry group Airlines for Europe (A4E) has already petitioned the European Commission to intervene in the market, proposing a joint fuel-purchasing system similar to the one established for natural gas following the invasion of Ukraine.
The prospect of a "toll booth" system, which Iran has reportedly begun applying to select vessels in the Strait of Hormuz, adds a layer of long-term systemic risk. Birol argued that allowing such a precedent to stand could permanently alter the economics of global maritime trade, potentially spreading to other vital chokepoints like the Malacca Strait. For now, more than 110 oil tankers and 15 LNG carriers remain trapped in the Persian Gulf, unable to transit the waterway. This maritime gridlock ensures that even if European reserves are managed through emergency rationing, the inflationary pressure on ticket prices will likely persist for years. Analysts at Morgan Stanley have already slashed 2026 EBITDA estimates for the sector by up to 16%, citing the inability of airlines to fully pass these historic costs onto consumers without crushing demand.
Skeptics of the IEA’s timeline point out that Europe has significant strategic petroleum reserves (SPR) that could be tapped to extend the six-week window. Furthermore, increased imports from U.S. Gulf Coast refineries and Asian suppliers via the Cape of Good Hope are beginning to ramp up, though at a significantly higher freight cost. These logistical workarounds may prevent a total collapse of European air connectivity, but they cannot erase the reality of a market where fuel availability is no longer a guarantee. As Birol noted, the recovery of pre-war production levels in the Middle East could take up to two years, leaving the global economy vulnerable to a prolonged period of energy-driven volatility.
