Iran’s closure of a critical shipping passage has forced a massive reshuffling of worldwide aviation fuel distribution, creating extraordinary shipping routes as companies work to maintain airline operations.
The blockade of the Strait of Hormuz has eliminated roughly 400,000 barrels daily of jet fuel shipments that previously flowed through the waterway, pushing European fuel costs beyond $200 per barrel in April – an unprecedented high.
Instead of experiencing severe fuel shortages, the aviation industry has witnessed dramatic changes in supply routing, with fuel shipments now crossing unprecedented distances as companies redraw their distribution strategies to sustain air travel.
This adaptation demonstrates the resilience of worldwide fuel distribution networks while simultaneously revealing potential vulnerabilities should the disruption continue.
European markets have compensated for much of the lost Middle Eastern fuel through increased shipments from the United States, Nigeria and India.
“It really does come down to who is shortest and most willing to pay,” said Sparta Commodities analyst James Noel-Beswick.
This market mechanism has enabled Europe to secure fuel supplies from distant locations by outbidding competing regions, though at the expense of extended transportation routes and elevated costs.
DISTRIBUTION NETWORKS STRAINED BUT FUNCTIONING
The International Energy Agency projects worldwide jet fuel consumption will reach 7.77 million barrels daily this year, showing minimal change from 2025 levels.
With Middle Eastern supplies restricted, purchasers are sourcing fuel from increasingly remote locations.
The tanker Nord Ventura completed a month-long voyage from Louisiana to transport approximately 300,000 barrels of aviation fuel to Melbourne, marking the first such delivery since at least 2017, based on Kpler tracking information.
European buyers have dispatched an unusual shipment to the Seychelles while importing supplies from New York Harbour, a region they traditionally serve as a supplier.
Asian markets have similarly attracted shipments from the U.S. Gulf Coast and African sources, while China has reduced exports to preserve domestic reserves.
Essentially, the marketplace is redistributing supplies on a global scale rather than depending on its most cost-effective transportation routes.
“Jet fuel has become so expensive that, with that price, the market is figuring out alternatives for supply chains,” said Wizz Air CEO Jozsef Varadi.
Thus far, this adaptability – combined with inventory building and refinery modifications – has helped offset the loss of Hormuz shipments.
MOUNTING STRAIN
Nevertheless, extended disruption makes this balancing effort increasingly challenging.
Storage levels already show stress. Independent reserves in Europe’s Amsterdam-Rotterdam-Antwerp hub have dropped to their lowest point since March, while Singapore middle distillate inventories approach two-month minimums. Europe continues struggling to completely replace lost shipments, despite elevated pricing.
“The medium-term is the bigger concern,” said Noel-Beswick of Sparta. “If the conflict drags on with no resolution in sight, we could start to see real tightness emerge towards late August and into early September.”
The IEA has indicated Europe might begin experiencing jet fuel shortages by June.
The challenge extends beyond availability to encompass cost factors. Extended routes, increased insurance premiums and competitive bidding all contribute to rising prices, creating risks that supplies remain accessible but increasingly costly.
CARRIERS MANAGING DISRUPTION – TEMPORARILY
Airlines have handled the crisis better than anticipated. Though jet fuel represents 30% to 40% of operational expenses, robust travel demand has enabled carriers to transfer some cost increases through higher ticket prices.
Industry estimates indicate airlines will face an extra $14 billion in fuel expenses during 2026, yet most have prevented major schedule disruptions.
Airport authorities and governments have helped absorb the impact through reserve building or relaxed import regulations, including Britain’s decision to continue allowing fuel imports refined from Russian crude in third countries.
However, early indicators suggest higher costs are reducing demand. The operator of Frankfurt airport, Germany’s busiest, has cautioned that rising fares might impact passenger volumes this year, now projected at the lower range of its 65 million to 66 million estimate.
Extended closure of the Strait of Hormuz will intensify pressure across shipping, refining and storage sectors – potentially driving prices even higher.
Consultancy Wood Mackenzie projects that continued disruption through late 2026 could push jet fuel prices in major markets toward $300 per barrel.
