European Jet Fuel Reserves Fall Below 30 Days Amid Tensions with Iran
Europe is currently facing extreme operational vulnerability due to critically low jet fuel inventories, Reuters reports. Despite an increase in emergency imports from the Americas and Asia, escalating geopolitical tensions in the Middle East leave the continent highly exposed to severe supply disruptions at the height of the peak summer travel season.
A Market at its Limit: Less Than a Month of Cover
European commercial aviation infrastructure is currently operating with razor-thin safety margins. According to calculations based on industry data, Europe’s jet fuel stockpiles offer less than 30 days of demand cover, making the region the most vulnerable to any logistical or supply-chain shocks.
At the beginning of June 2026, European inventories stood at a mere 38 million barrels, an alarming figure when compared to the 99 million barrels available in the United States. Projections from consultancy firm Energy Aspects foresee a complex outlook for the third quarter of the year, estimating a severe supply deficit in Europe compared to surpluses in other global regions:
- Europe: Projected deficit of 600,000 barrels per day (bpd)
- United States: Projected surplus of 116,000 bpd
- Asia-Pacific: Projected surplus of 425,000 bpd
Meanwhile, provisional data from the International Energy Agency (IEA) indicated that although stockpiles at the end of May were 10% higher year-on-year and refinery output had risen by 30%, the actual operational buffer for airlines remains capped at a single month.
Structural Vulnerability and the Geopolitical Factor
The current fragility is not an isolated event, but rather the direct consequence of decades of refinery closures across Europe, which has steadily driven up its dependence on imports. Historically, before conflict erupted in late February following US and Israeli airstrikes that triggered a war with Iran, Europe relied on the Middle East for approximately 50% of its jet fuel imports.
The primary chokepoint is the Strait of Hormuz, a strategic maritime route through which nearly one-fifth of the world’s oil and liquefied natural gas (LNG) passes. Although the strait partially reopened in June, fragile truces in July have been threatened by attacks from both sides, keeping nations such as Great Britain, France, and Germany—the most vulnerable to disruptions in these maritime flows—on high alert.
It was initially anticipated that African countries, which sourced nearly all of their fuel from the Middle East, would bear the brunt of the February crisis. However, these markets managed to mitigate the impact by ramping up procurement from the Dangote refinery in Nigeria, as well as from India and Oman.
Logistical Realignment: Transatlantic and Transpacific Routes
To avoid a grounding of air transport services, European importers have had to drastically restructure their supply chains by turning to new global suppliers. During June, total jet fuel imports reached 673,000 bpd, the highest volume recorded since October 2025, according to data from commodity intelligence firm Kpler.
New trade flows into Europe:
- United States and Nigeria: Solidified their positions as the largest exporters to the European market.
- Canada and South Korea: Emerged as strategic alternative suppliers, providing critical spot cargoes.
- India: Recorded its highest export volumes to Europe in June since February.
- Kuwait: Formerly a major supplier to the region, Kuwait will resume deliveries in August at approximately 25,000 bpd via a ship-to-ship transfer on the vessel Proteus Harvonne, marking its first shipment since early March.
On the domestic front, local refining has attempted to absorb the shock. Refineries in Italy increased their jet fuel production by 10% during the first four months of the year. Concurrently, Italian imports fell by 6%, allowing domestic refining to cover nearly 70% of national demand between March and April, according to data from UNEM (the Italian energy association for independent operators). Industry leaders such as Eni, which controls half of Italy’s refining capacity, boosted throughput by importing semi-finished products from outside Europe.
Financial and Operational Impact on Airlines
Despite operational strain on the supply side, the energy market has provided temporary financial relief to airlines. Northwest European jet fuel prices eased to around $133.27 per barrel, retreating from the historic peak of $215.32 per barrel reached in late March. This decline eases cost pressure on operators, given that fuel typically accounts for 20% to 25% of an airline’s total operating expenses.
Nevertheless, analysts rule out any immediate drop in airfares. Passenger demand remains robust and seat capacity is constrained, particularly after multiple carriers decided to trim schedules to optimize and preserve their available fuel reserves.
Next Steps for the European Union
The short-term horizon remains cautious for the European aviation industry. Analysts at Rystad Energy estimate that market tightness will persist through August under current consumption rates.
Against this backdrop, European Union Energy Commissioner Dan Jørgensen acknowledged that the bloc faces even tighter jet fuel inventories heading into the end of the summer holiday season. Consequently, the European Commission has confirmed that it stands ready to coordinate the release of member states’ strategic national stockpiles should operational conditions require it to keep aircraft flying.
