- Global Fuel Supply Crisis Deepens as Strait of Hormuz disruption cuts 21% of global jet fuel flows
- Airlines across Asia and Europe slash flights and impose fuel surcharges amid shortages
- Analysts warn of prolonged aviation disruption and rising global economic risks
- Competition for U.S. crude surges as refiners scramble to replace Middle East supplies
The global aviation and energy sectors are facing mounting disruption as the ongoing Iran war triggers a severe fuel supply crunch, forcing airlines to cut flights, governments to consider rationing, and markets to scramble for alternative energy sources.
The closure of the Strait of Hormuz—one of the world’s most critical energy chokepoints—has choked off nearly 21% of global seaborne jet fuel supply, according to industry estimates. Unlike previous oil shocks driven primarily by price spikes, this crisis is constraining physical supply, raising alarm across Asia, Europe, and parts of Africa.
Airlines across Asia have been among the first to respond. Several carriers are now carrying extra fuel from their home bases, adding refuelling stops, or reducing cargo loads to cope with limited availability at destination airports. In more severe cases, airlines are cutting flights altogether.

“In my conversations with airline operators, there is deep concern about how long this disruption will last,” said Shukor Yusof, founder of Endau Analytics. “The uncertainty is unprecedented because supply chains from the Gulf are effectively frozen.”
The impact has been particularly severe in import-dependent economies such as Pakistan, Vietnam, and Myanmar. Aviation authorities in these countries are already reporting flight reductions and fuel conservation measures. In Pakistan, pilots have been advised to tanker fuel from foreign airports—a costly strategy that increases aircraft weight and fuel burn.

Brendan Sobie, an independent aviation analyst based in Singapore, noted that some governments are quietly prioritizing domestic carriers over foreign airlines. “We are seeing early signs of fuel protectionism,” he said. “Countries fear running out, so they are limiting supply to international operators.”
The ripple effects are now spreading to Europe, where airlines are bracing for similar constraints in the coming weeks. Michael O’Leary, CEO of Ryanair, warned that if fuel supply drops by even 10–20% during peak summer months, widespread flight cancellations may become inevitable.
“We are entering a scenario where capacity cuts are no longer optional—they are necessary,” O’Leary said in a recent briefing.

Meanwhile, jet fuel prices have more than doubled since the start of the conflict, pushing airlines into what industry insiders describe as “crisis mode.” Several carriers have already introduced fuel surcharges or raised ticket prices, while others are scaling back operations to limit financial exposure.
Chandran Rama Muthy, CEO of Batik Air Malaysia, described the situation as a “proactive response to an evolving emergency,” after the airline slashed domestic capacity by over one-third.
Despite these measures, analysts warn that demand destruction is not keeping pace with supply losses. According to energy consultancy Energy Aspects, at least 400,000 barrels per day of jet fuel production linked to Hormuz transit routes has been disrupted.
“There is no easy replacement for these volumes,” said Alex Yap, senior oil products analyst at the firm. “Refiners outside the region are already stretched, and logistical bottlenecks are compounding the problem.”

Global competition for alternative crude supplies has intensified sharply. Asian and European refiners are now bidding aggressively for U.S. and Atlantic Basin oil, driving spot premiums to record highs. Traders report that U.S. crude shipments to Asia are being sold at premiums of up to $40 per barrel above benchmark prices.
Paola Rodriguez-Masiu, chief oil analyst at Rystad Energy, said the market is entering uncharted territory. “Asian refiners, shut out of Middle Eastern supply, are bidding for every available barrel. This is pushing costs to unsustainable levels and eroding refining margins globally.”
Governments, meanwhile, are beginning to weigh emergency responses, including fuel rationing and strategic reserve releases. However, policy coordination remains uneven, raising fears of prolonged instability.
Foreign policy experts warn that the energy shock could trigger broader economic consequences if the conflict persists. “This is not just an aviation crisis—it’s a systemic energy disruption,” said a senior energy security analyst based in London. “If the Strait of Hormuz remains closed, global trade and economic growth will take a significant hit.”
China, the world’s second-largest economy, appears relatively better positioned due to its diversified energy mix and large coal reserves. However, Beijing has already signaled urgency in accelerating renewable energy development and strengthening energy security frameworks.
As the crisis deepens, industry leaders agree that the coming weeks will be critical. With no clear timeline for the reopening of key supply routes, the global fuel supply chain remains under intense strain.
“The market is reacting day by day,” one senior oil trader said. “Every morning brings a new price, a new risk, and a new level of uncertainty.”
Unless diplomatic efforts succeed in stabilizing the region, analysts warn that the world could be heading toward a prolonged energy crisis—one that reshapes aviation, trade, and global economic stability for months to come.
