Grounded: How a $5.8 Billion Fuel Bet Went Wrong for the World's Airlines

The global airline industry entered 2026 with fuel costs at comfortable lows and most major carriers betting they could ride out volatility without financial protection. That bet has now gone catastrophically wrong. The escalation of the U.S.-Israeli war on Iran, the effective closure of the Strait of Hormuz, and the resulting spike in jet fuel prices have exposed the aviation sector's greatest financial vulnerability in a generation — and the hedging strategies that were supposed to prevent this are proving woefully inadequate.

The Perfect Storm: From $60 Oil to a Supply Shock

At the start of 2026, crude oil was what J.P. Morgan called "the forgotten commodity" [1]. WTI crude traded near $60 per barrel in January, and the U.S. Energy Information Administration forecast a structural oversupply that would drag prices toward $58 per barrel [2]. Airlines were planning for a benign fuel environment. Some analysts expected jet fuel to average around $88 per barrel for the year [3].

Then the geopolitics shifted. Following the escalation of military action between the United States, Israel, and Iran in late February, and the subsequent effective closure of the Strait of Hormuz on March 9, the energy market was upended overnight [4]. Brent crude surged over 20% in a single trading session, settling at $94 per barrel. WTI crude rose from roughly $67 at the end of February to $94.65 by March 9 — a gain of more than 40% in under two weeks [5].

But crude oil tells only part of the story. Jet fuel prices — which track crude but are heavily influenced by refining margins — have doubled since the conflict intensified, far outpacing crude's one-third rise [6]. In just one week, the global average price of jet fuel surged by 58.4%, reaching $157.41 per barrel [7]. Some benchmarks have traded as high as $200 per barrel, levels not seen since the pandemic-era commodity shock.

The refining spread — the margin between crude oil and refined jet fuel — spiked to as high as $144 per barrel before easing to around $65, still far above normal levels [6]. This widening crack spread is the central reason why airline hedging programs, almost universally designed to protect against crude oil price increases, are failing to shield carriers from the actual cost they pay for jet fuel.

The Great Hedging Retreat

To understand why the industry is so exposed, one must look back at a decade of strategic retreat from fuel hedging by America's largest airlines.

Delta Air Lines, American Airlines, and United Airlines all exited the fuel hedging arena roughly ten years ago [8]. The rationale was partly economic: hedging is expensive, and during periods of falling oil prices, hedging contracts can turn into costly liabilities. It was also partly strategic — these mega-carriers believed their scale and purchasing power gave them enough leverage to negotiate competitive fuel prices directly with suppliers.

The final domino fell in March 2025, when Southwest Airlines — historically the industry's most prolific fuel hedger and once credited with saving billions through its forward-looking fuel contracts — announced it was abandoning the practice entirely [9]. Southwest CEO Bob Jordan told an investor conference that "with the exception of a couple of positive years, it's not been beneficial to the company for the past 10 to 15 years" [8]. The airline had paid $157 million in hedging premiums in recent years with diminishing returns.

As of March 2026, none of the four largest U.S. carriers — Delta, United, American, or Southwest — have hedging contracts in place [8]. They are fully exposed to jet fuel prices at the spot market, and the consequences are staggering.

The $5.8 Billion Hit

Reuters calculations indicate those four U.S. carriers are looking at a combined $5.8 billion in additional fuel costs if jet fuel prices remain at elevated levels for the full year [8]. Delta's management recently disclosed that a sustained 10% increase in fuel alone would add $1 billion to its 2026 fuel bill [8]. At current prices — with jet fuel roughly double where it started the year — the math is far worse.

Each major U.S. airline could be confronting approximately $1.5 billion or more in added quarterly fuel expenses at the elevated prices, according to IndexBox analysis [10]. That burden has already slammed airline equities. On March 5, airline stocks suffered their worst single-day rout in over a year, led by a 6.5% plunge in American Airlines shares [11]. United Airlines dropped as much as 8.7% in early trading on March 9 [11]. Year-to-date, Delta, American, and United have fallen between 20% and 30%, while Southwest, JetBlue, and Alaska Airlines have experienced declines of approximately 30% over one month [10].

Europe's Partial Shield

European carriers present a starkly different picture — but one that is far from comfortable. While many European airlines maintained substantial hedge coverage extending several years into the future, the nature of those hedges is proving to be a double-edged sword [12].

IAG, owner of British Airways and Iberia, is hedged to 75% for the first quarter of 2026, declining to 64% in the second quarter, 58% in the third, and 50% in the fourth [13]. That declining coverage means the airline's exposure grows with each passing quarter. Ryanair, with its disciplined low-cost model and strong hedging position, appears relatively better insulated, while budget carrier Wizz Air faces potentially the steepest impact — a sustained 10% increase in jet fuel prices could slash its operating profit by as much as 31% [6].

The most alarming case may be Lufthansa. Morgan Stanley analysts flagged the German flag carrier as particularly vulnerable, warning that if jet fuel prices remain at current elevated levels, its fuel bill could rise more than 35%, potentially eroding up to 88% of its forecast 2026 operating profit in a worst-case scenario [13].

A critical distinction separates European hedging strategies. Low-cost carriers such as easyJet and Wizz Air tend to hedge directly against jet fuel prices, which provides more accurate protection against the actual cost they face. Traditional flag carriers like Lufthansa and Air France-KLM more commonly hedge against Brent crude or gasoil as a proxy, then layer on jet fuel-specific hedges closer to departure dates [13]. When the crack spread between crude and jet fuel explodes — as it has now — crude-based hedges offer only partial protection.

Asia's Mixed Exposure

The picture across Asia is fragmented. China's three major airlines — Air China, China Eastern, and China Southern — carry no fuel hedges, leaving them entirely exposed to the price surge [12]. This is particularly significant given that Chinese carriers collectively represent one of the world's largest aviation fuel markets.

Singapore Airlines and Virgin Australia stand out as having stronger protection against refined fuel price spikes [6]. But Cathay Pacific, despite maintaining hedging programs, illustrates the systemic problem: its hedging contracts are based on crude oil rather than jet fuel. CFO Rebecca Sharpe acknowledged the gap, noting that while the airline has some protection from crude hedging, "it's not protecting against the jet fuel price in totality" [6]. Sharpe also highlighted why so few carriers hedge jet fuel directly: "The market is very thin and it makes it very expensive" [6].

Morgan Stanley analysis estimates that Asian airlines' 2026 net profits could drop by an average of 6% for each $10 per barrel increase in refining margins sustained over 90 days, assuming no pricing offsets [6].

The Crack Spread Problem

At the heart of the hedging failure is a structural issue the industry has never fully solved: the crack spread. Airlines consume jet fuel, but the global derivatives market for jet fuel is thin, illiquid, and expensive to trade [6]. Most hedging is therefore done using crude oil futures — Brent or WTI — as proxies. In normal times, jet fuel prices track crude reasonably well, and the proxy hedges work.

But these are not normal times. The Strait of Hormuz closure has disrupted not just crude supply but also the refining capacity concentrated in the Gulf region. Refineries in Saudi Arabia, the UAE, and Qatar that would normally process crude into jet fuel are operating under extreme logistical constraints [4]. The result is a supply squeeze specific to refined products that crude oil hedges cannot capture.

The refining spread surging to $144 per barrel before easing to $65 — compared to a historical average far below that — means airlines with crude hedges are covering perhaps a third of their actual cost increase [6]. It is, as one analyst described it, the equivalent of insuring your house against floods but not fires, only to have a fire break out.

Passengers Pay the Price

Airlines are moving swiftly to pass the pain to consumers. Hong Kong Airlines raised fuel surcharges by up to 35.2% [14]. Air India and Air India Express introduced phased surcharges starting March 12 on both domestic and international routes [14]. Air New Zealand added surcharges ranging from NZ$10 on domestic flights to NZ$90 on long-haul routes [14]. In the United States, Delta, United, American, Southwest, Alaska, JetBlue, and Hawaiian all hiked fares on international routes as jet fuel costs surged [15].

Beyond ticket price increases, carriers are beginning to prune their 2026 capacity plans, particularly on thinner or marginally profitable routes [7]. Over 21,300 flights were cancelled globally in the first week of March alone, driven both by airspace closures over the Middle East and by the economic calculus of operating at a loss [11]. Airlines rerouting away from contested airspace face hours-long detours that further increase fuel burn and crew costs per flight [7].

For leisure travelers planning family vacations or long-distance trips, the combined impact of higher fares and reduced route options could significantly alter summer 2026 travel plans. Analysts at The Points Guy are advising consumers to book summer flights immediately, before additional surcharges take effect [16].

What Comes Next

The EIA forecasts that Brent crude will remain above $95 per barrel over the next two months before falling below $80 in the third quarter of 2026 and to around $70 by year-end [2] — but that forecast assumes the Strait of Hormuz disruption will gradually ease and production flows will resume. If the standoff persists, or if Iranian IRGC Commander statements that "not a litre of oil" will pass through the strait prove accurate [17], price levels could remain elevated far longer than markets currently expect.

The International Energy Agency has already taken the unprecedented step of announcing it would release 400 million barrels of oil from strategic reserves [4]. Saudi Arabia is reportedly considering rerouting some crude exports through its Red Sea port at Yanbu to bypass the closed strait [4]. But these are stopgap measures. The fundamental disruption to both crude supply and refining capacity in the Gulf has no quick resolution.

For the airline industry, the crisis is forcing a painful reckoning. The decade-long retreat from fuel hedging — driven by the logic that hedging was too expensive and too unreliable — has left carriers nakedly exposed at precisely the moment protection was needed most. European airlines with hedging programs are faring better, but even their crude-based hedges are proving insufficient against the jet fuel-specific price shock.

The lesson is clear, even if the solution is not: hedging against crude oil is not the same as hedging against jet fuel, and abandoning hedging altogether is a bet that the world will remain geopolitically stable. In March 2026, that bet has been called — and the industry is paying the price.
