Six Weeks Left: Europe's Jet Fuel Clock Is Ticking

Alpha One

17 Apr 2026 • 6 min read

Europe is six weeks from running out of jet fuel. That's not a forecast. That's the International Energy Agency's warning, issued yesterday by executive director Fatih Birol. "I can tell you soon we will hear that flights from city A to city B might be cancelled," he said.

The culprit: the Strait of Hormuz, which has been effectively closed since late February when Iran mined the waterway and warned off international shipping as the US-Iran war escalated. The Gulf supplies roughly 41% of Europe's jet fuel imports. With tanker traffic near zero and strategic reserves burning fast, airlines are staring at a summer of cancellations, rationing, and financial ruin — while investors face a starkly binary trade.

The Numbers Behind the Crisis

The scale of the disruption is hard to overstate. Roughly 10 million barrels per day of oil that would normally flow through Hormuz is blocked. For Europe's aviation sector, the specific exposure is acute: the region imports the majority of its jet fuel from Gulf refineries, which produce the world's largest volumes of aviation kerosene.

Jet fuel prices have nearly doubled since the conflict began — from around $831 per tonne pre-war to $1,838 per tonne today. For an industry where fuel accounts for 25–30% of operating costs, that's not an inconvenience. It's an existential threat.

The IEA's warning this week put a number on it: if Hormuz remains closed, Europe's jet fuel reserves will be exhausted in roughly six weeks — sometime in late May or early June. The Airports Council International (ACI) Europe has been even more alarmist, warning of "systemic shortages" potentially within three weeks at some airports.

Airlines in the Crossfire

The damage is already showing up in earnings and stock prices.

Ryanair (RYAAY) — Europe's largest carrier by passenger volume — has warned that fuel suppliers are only guaranteeing deliveries through mid-May. CEO Michael O'Leary says roughly 25% of summer fuel supplies are "at risk" from June onward. The stock has hit five-month lows. In a worst-case scenario, O'Leary has flagged potential cuts of around one in ten flights.

EasyJet (EZJ.L) has taken the harshest financial hit. The airline reported £25 million in additional fuel costs in the first half of the year alone, forcing it to widen its loss guidance to £540–560 million for H1 2026. Shares have fallen approximately 30% in three months, with multiple analyst price target cuts following. Bernstein has downgraded EasyJet in favor of more operationally efficient carriers.

Air France-KLM (AF.PA) has already canceled 160 flights through May, citing "unacceptably high kerosene costs." The stock is down roughly 23% in 30 days. Like its peers, it's calling for emergency EU intervention — specifically, coordinated reserve releases and alternative supply routing.

Wizz Air faces similar exposure, particularly given its heavy Eastern European footprint and reliance on Gulf-sourced fuel.

The pattern across the sector: airlines with stronger hedging books — primarily Ryanair and those with longer-duration fuel contracts — are better positioned in the short term. But hedging only works until it runs out. At current prices and supply levels, most carriers' hedges expire between May and August, after which they'll be fully exposed to spot market pricing — and potentially, no supply at all.

The Diplomatic Calendar and the Six-Week Window

This morning, a fragile 10-day ceasefire took effect between Israel and Hezbollah in Lebanon — brokered by the Trump administration. It's a partial signal that de-escalation is politically achievable. Trump stated the broader US-Iran conflict "should be ending pretty soon," with talks potentially resuming this weekend, possibly in Pakistan.

The problem: Iran's Deputy Foreign Minister has rejected any temporary truce, demanding a comprehensive regional settlement "from Lebanon to the Red Sea." That's a much higher bar than a 10-day pause.

Meanwhile, the Trump-Xi summit is scheduled for May 14–15 in Beijing — the first US presidential visit to China in eight years. China is actively using its leverage with Tehran to facilitate a smoother path to that summit, and both sides want Hormuz reopened before Boeing jets and agricultural deals land on the table. That's a genuine diplomatic incentive working in the background.

But even if a deal is reached this weekend, the physical reopening of Hormuz — demining, safety clearances, resuming tanker traffic — could take weeks. Europe's jet fuel clock doesn't wait for diplomacy to complete its paperwork.

UK Prime Minister Starmer and France's President Macron co-hosted a video call yesterday with approximately 40 countries (excluding the US) to coordinate emergency supply rerouting and demining efforts. India confirmed participation. The scale of the coordination reflects the urgency: this isn't a localized fuel disruption. It's the largest energy crisis since the 1970s, according to the IEA.

What Comes Next

Three scenarios shape the outlook:

Resolution within 2–3 weeks. If US-Iran talks produce a deal this weekend and Hormuz begins reopening, physical fuel supplies could start flowing again by mid-May. Airlines weather the shock through hedging and fare hikes. Stock prices recover sharply. This is the scenario markets are partially pricing in today — the S&P 500 hit near-record levels yesterday on ceasefire optimism.

Stalemate through June. Iran holds out, talks stall, and Hormuz remains closed through the summer. Europe implements emergency rationing, flight volumes are cut by 15–25%, and airline stocks decline another 20–40%. The IMF's worst-case forecast — global growth at 2.5% for 2026 — starts looking optimistic.

Partial reopening, partial supply. A ceasefire allows limited tanker traffic but not full restoration. Jet fuel prices stay elevated but pullback from peak. Airlines still face painful fare hikes and selective cancellations, but systemic collapse is avoided.

The market's current bet — risk assets rising, oil dipping on ceasefire news — reflects optimism about scenario one. The IEA's warning reflects the reality that scenario two is still very much in play.

The Investment Angle Nobody's Pricing Correctly

Here's what gets lost in the noise: the jet fuel crisis isn't just a problem for airlines. It's a stress test for the entire European summer economy — and it's barely priced into travel-adjacent stocks.

Hotel groups, tourism operators, cruise lines, and airport operators all depend on people getting on planes. If European flight volumes drop by 20% this summer, the ripple effects extend well beyond aviation balance sheets.

Conversely, the companies positioned to profit from this dislocation include: alternative aviation fuel producers (SAF manufacturers), pipeline infrastructure operators with non-Gulf routing, refineries with North Sea or US Gulf Coast output currently being rerouted to Europe, and fuel hedging and energy derivatives traders.

The ceasefire news today will generate a relief rally. Whether that rally is justified depends entirely on whether the next 10 days of diplomacy produce something durable — or whether the six-week clock simply keeps ticking.
