The Jet Fuel Panic Was Overblown

When the US-Iran conflict closed the Strait of Hormuz in early 2026, the European aviation industry braced for a fuel crisis that would ground fleets and gut summer schedules. The crack spread, the refinery premium on jet kerosene over crude, spiked from a historical average of $16 per barrel to nearly $100, a move that Crack The Market documented in real time through interviews with institutional energy traders and a two-part series on the refining crisis. Seven Italian airports restricted fuel access. Lufthansa drafted contingency plans to park 40 aircraft. Spreads on Air France-KLM bonds blew out to 500 basis points in mid-January as credit markets priced in a sustained physical shortage.

Six months later, the shortage everyone feared has largely failed to arrive. US refiners pushed jet fuel yields to a record 12.5%, exceeding 2 million barrels per day in output, and by May roughly half of American jet fuel exports were heading to Europe. Nigeria’s Dangote refinery, whose role in reshaping global refining geography Africatalyst has covered extensively, shipped 525 million liters in a 50-day window. Additional volumes came from India, South Korea, and the Netherlands. The 300,000 barrels per day that disappeared from the Hormuz corridor were replaced, and spot jet fuel prices settled around $950 per metric ton by June, down from an early-April peak near $1,800.

The panic was especially misplaced for short-haul operations. A 737 burning 2,500 kilograms on a two-hour sector faced a per-flight cost increase that, while meaningful in aggregate, was entirely manageable through modest fare adjustments and a strong hedge book. Short sectors burn less fuel per passenger, and the operational flexibility to swap routes or adjust frequencies gives these carriers a lever that long-haul operators simply do not have. The fuel shock was an earnings headwind for low-cost carriers, never an existential threat, and the market took months to price that distinction correctly.

What the crisis did produce is a clean separation of European airlines into three tiers based on how their fuel strategies actually performed under stress.

The airlines that got stronger. Ryanair hedged 80-84% of FY26 and FY27 consumption at approximately $668 per metric ton, well before the crisis escalated. With spot prices running at nearly triple that level through the spring, the hedge book functioned as a billion-euro annual cost advantage. The airline generated €1.8 billion in free cash flow, repaid its final €1.2 billion bond, and now holds €3.6 billion in gross cash with zero net debt. IAG followed a similar trajectory through a different mechanism: its transatlantic premium traffic, where passengers absorb fare increases with minimal pushback, compensated for declining hedge coverage through the year. IAG produced €3.15 billion in free cash flow and holds net leverage of 0.8x EBITDA, the lowest among European network carriers. Both credits exited the crisis in better shape than they entered it.

The airlines that survived with thin margins. EasyJet maintains a net cash position and £4.7 billion in liquidity, which is a solid defensive posture, but its exposure to the oversupplied UK short-haul leisure market means pricing power is limited precisely when costs are rising. Consensus projects easyJet’s free cash flow turning negative at -£492 million for FY26. Lufthansa sits at BBB-, the lowest rung of investment grade, and its hedge book exposed a structural weakness that Edward Finley—Richardson ’s work on petroleum product economics helps explain: the airline hedges through Brent crude and gas oil contracts rather than jet kerosene directly, which meant the entire basis risk of the crack spread blowout fell on the P&L unhedged. The 2026 fuel bill reached an estimated €8.9 billion, 20,000 summer flights were scrubbed, and projected free cash flow sits at roughly €340 million with almost no room for another shock.

The airlines that remain exposed. Air France-KLM, already rated BB+ and carrying pandemic-era hybrid debt, hedged only 47% of Q4 consumption and 33% of FY27. Free cash flow is projected negative for FY26, and the bond market’s round-trip from 500 basis points in January to under 70 by late April tells the story of a repricing that overshot in both directions. Wizz Air occupies a category of its own at 3.9x net debt to EBITDA, unrated by S&P, with heavy equity short interest and restricted access to bond markets. These are carriers where the next fuel shock, if it comes with the forward curve still 35-40% above pre-conflict levels and FY27 hedge books at a third of consumption, will find balance sheets that have used up most of their cushion already.

The lesson from the first half of 2026 is that the global refining system proved more elastic than the market expected, that short-haul economics provide a natural buffer against fuel shocks, and that the gap between airlines hedging actual kerosene and those hedging proxy instruments on crude or gas oil turned out to be the single most important variable in the sector. The panic sold a story of grounded fleets and empty airports. What actually happened was a supply chain that bent, repriced, and adapted, while the credit bifurcation that already existed in European aviation became permanent.

As Brian Sumers and Alex Macheras have both noted from different angles, the sector that emerges from this crisis looks structurally different from the one that entered it. The question for the next twelve months is whether the airlines sitting on thin FY27 hedge books will use the current window to rebuild coverage, or whether they will wait for prices that may never come back down.
