Jet Fuel Crunch From Iran War Set to Drag On for Months: IATA

Global airlines are bracing for a prolonged jet fuel crunch after the International Air Transport Association indicated supplies and prices could take months to recover from war-related disruptions around the Strait of Hormuz, even if the vital oil corridor fully reopens.

War Disruption Hits a Critical Refining Hub

Published coverage of recent remarks from International Air Transport Association leadership highlights the scale of the shock triggered by the Iran war and weeks of disruption in the Strait of Hormuz. The narrow waterway is a key outlet for crude from major Middle East producers, but it is also closely tied to the region’s refining network, which plays an outsized role in global jet fuel supply.

Reports indicate that attacks and shutdowns linked to the conflict have sidelined significant refining capacity in the Gulf. This has choked flows of aviation fuel to Asian, European and African markets that rely heavily on Middle East cargoes. Even as crude shipments show signs of resuming, the loss of processing capability means refineries elsewhere cannot quickly backfill the gap without reconfiguring runs or diverting output from other fuels.

IATA’s latest analysis and other public data underscore that airlines are exposed not just to headline oil prices but to refining bottlenecks that push the jet fuel premium above crude. Recent industry charts show the so‑called crack spread widening again, reflecting tighter supplies of refined products compared with underlying oil benchmarks.

The association has framed this war-driven shock as part of a broader pattern in which regional conflicts and shipping disruptions have repeatedly unsettled jet fuel markets since the invasion of Ukraine, with the latest Middle East hostilities emerging as one of the most severe tests yet.

Months Needed to Rebuild Fuel Supply Chains

According to multiple news reports on IATA’s comments this week, rebuilding jet fuel supply chains will not be instantaneous even if a ceasefire holds and safe passage through Hormuz is restored. Storage tanks need refilling, damaged or idled refining units must return to service, and complex trade routes require rebalancing as cargoes are rescheduled and shipping capacity reallocated.

Publicly available information from airline briefings and IATA economic updates suggests that the process could stretch over several months as global inventories are rebuilt from unusually low levels. Some refiners have been prioritising diesel and other middle distillates, while others have already committed volumes to long-term contracts, limiting their ability to pivot quickly toward aviation fuel.

Analysts tracking the sector indicate that the current crunch is more than a short-lived price spike. Jet fuel markets were already tight after years of refinery closures in Europe and structural underinvestment in new capacity. The sudden loss of Middle East refining output has compounded these vulnerabilities, leaving airlines especially sensitive to any further logistical snags or geopolitical flare-ups.

For carriers planning schedules and capacity into the peak northern summer, the expectation of a multi-month recovery means fuel procurement teams must work with a longer horizon of uncertainty, negotiating alternative supplies and factoring elevated costs into their financial outlooks.

Airlines Confront Higher Costs and Operational Risks

Fuel is typically the second-largest expense for airlines after labour, and IATA data indicate it can account for around a quarter to a third of operating costs. With jet fuel prices now trading at a premium to crude benchmarks, carriers face immediate margin pressure just as global passenger demand has been nearing or surpassing pre-pandemic levels.

Industry reports describe a range of responses, from more aggressive fuel hedging where instruments are available, to targeted surcharges on tickets and cargo, to tighter management of non-fuel costs. Some airlines are reassessing marginal routes that rely on thinner yields, particularly long-haul services where fuel represents an even larger share of total trip expenses.

Operationally, the disruption is most acute at airports that depend on imports from Gulf refiners. Travel-sector coverage points to contingency measures such as increased tankering, in which aircraft load extra fuel at less affected hubs to reduce uplift at constrained locations. While this can safeguard operations in the short term, it also adds weight, raises fuel burn, and complicates network planning.

Smaller and financially weaker carriers may find it harder to absorb the shock. Elevated fuel costs, tighter credit conditions and competition for limited supply could accelerate consolidation in some regions, reshaping the competitive landscape just as traffic recovery had started to broaden beyond major network airlines.

Regional Travel Markets Feel Uneven Impacts

The impact of the jet fuel crunch is not evenly distributed. Asia-Pacific carriers, many of which operate dense networks connecting to the Gulf and South Asia, are heavily exposed to Middle East supply outages. Reports from regional media describe concerns about higher costs on key trunk routes and the potential need to adjust frequencies or aircraft types if fuel availability becomes constrained.

In Europe, long-haul operators to the Middle East and Asia are grappling with both higher prices and longer routings around conflict zones. IATA economic commentaries in recent months have already flagged Europe’s growing structural deficit in jet fuel due to refinery closures, leaving the region especially reliant on imports that are now harder to secure at competitive prices.

North American airlines, by contrast, benefit from relatively large domestic refining systems and stronger pipeline and storage networks, although they are not insulated from global price dynamics. Market data show that even where physical supply is secure, jet fuel prices have risen in line with international benchmarks, feeding through to higher operating costs on transatlantic and transpacific routes.

In emerging markets, including parts of Africa and South Asia, aviation stakeholders have warned that any prolonged shortage could force capacity cuts. Limited storage, fewer alternative suppliers and weaker bargaining power can leave local carriers more vulnerable to supply interruptions or steep price increases.

Longer-Term Questions on Energy Security and Transition

The latest jet fuel shock is reinforcing questions about energy security for aviation and the pace of the sector’s transition away from fossil fuels. IATA’s own sustainability assessments show that sustainable aviation fuel still represents a very small share of overall jet consumption, leaving airlines overwhelmingly dependent on conventional kerosene refined from crude oil.

Industry research points to a structural mismatch between growing long-haul air travel demand and constrained refining capacity tailored to aviation fuels. As older refineries in developed markets shut down or shift toward petrochemicals and renewable diesel, and new projects face lengthy permitting and financing hurdles, the global system has less slack to absorb sudden regional outages.

For travel markets, the implications extend beyond near-term fares. Tour operators, destination marketing organisations and airport authorities must incorporate the risk of energy price spikes into their long-range planning. Some tourism-dependent economies could see visitor flows become more volatile if repeated fuel shocks lead to higher ticket prices or reduced connectivity.

Policy discussions are increasingly focused on how to balance support for sustainable aviation fuel scale-up with the immediate need for reliable conventional jet supplies. While SAF is central to meeting long-term climate goals, analysts caution that it cannot yet offset large disruptions in fossil-based jet output, leaving the global travel industry exposed to the kind of war-driven volatility now radiating out from the Strait of Hormuz.
