Europe is heading toward a potentially significant jet-fuel supply deficit in the fourth quarter of 2026 as disruptions to Middle Eastern energy flows continue to tighten refined-product markets and reduce regional inventories.
Energy consultancy Energy Aspects forecasts that Europe’s jet-fuel market could face a deficit of about 510,000 barrels per day during the fourth quarter, according to Reuters. The projection comes despite European buyers increasing imports from distant suppliers, including South Korea.
The expected shortfall reflects the combined effect of disrupted Middle Eastern exports, depleted European fuel inventories and limited spare refining capacity.
It does not mean European airlines are currently facing a complete inability to obtain jet fuel. Rather, it indicates that projected regional demand could exceed readily available supply during the final quarter of the year if current market conditions persist.
Middle East disruption reshapes Europe’s fuel market
The Middle East has historically been an important source of refined petroleum products for international markets.
The continuing conflict and restrictions around key shipping routes have disrupted those flows, forcing European buyers to seek supplies from increasingly distant producers.
The Strait of Hormuz has been particularly important to the disruption because of its role in global energy transportation.
Reduced flows through the region have affected not only crude oil but also refined products such as diesel and jet fuel.
The International Energy Agency said in its August Oil Market Report that Middle Eastern product-export disruptions and attacks on infrastructure had reduced refinery output estimates, while tight light and middle-distillate markets had pushed refining margins in the Atlantic Basin to record levels.
European jet-fuel inventories fall
European fuel inventories have become one of the clearest signs of the tightening market.
Stocks at the Amsterdam-Rotterdam-Antwerp trading hub had fallen to their lowest level in seven years, according to Reuters.
The ARA region is an important storage and trading centre for refined petroleum products serving northwest Europe.
Lower inventories leave the market with less of a buffer against additional supply disruptions.
If imports increase or refinery output improves, the inventory decline can stabilise.
If supply remains constrained while aviation demand continues, however, stocks could come under further pressure.
South Korea becomes a major supplier
European buyers have increasingly turned to Asia to replace some of the fuel previously obtained from closer markets.
South Korea has emerged as one of the most important new suppliers.
Europe imported approximately 129,000 barrels per day of jet fuel from South Korea in September, according to Reuters. That was the highest monthly flow from South Korea to Europe since October 2022.
The increase demonstrates how global fuel markets can redirect supplies when price differences make long-distance shipments commercially attractive.
South Korean refiners can send more jet fuel toward Europe when European prices rise sufficiently relative to Asian prices to cover transportation and other costs.
South Korean production reaches high levels
South Korea has also increased jet-fuel production.
Reuters reported that South Korean jet-fuel output in July reached nearly 13.89 million barrels, the highest level in seven years. Higher refinery crude-processing rates supported the increase.
Additional production has helped South Korea become an important source of replacement supply for European buyers.
The country is not the only Asian supplier available to Europe, but its refining capacity and location make it an increasingly important part of the market’s response to the disruption.
Long-distance imports come at a cost
Shipping jet fuel from Asia to Europe is more expensive and takes longer than sourcing it from nearby suppliers.
However, the price difference between Asian and European fuel markets has become large enough to make some long-distance shipments commercially attractive.
The higher European price can compensate traders and refiners for additional transportation costs.
This process helps redirect fuel toward the market where it is most valuable.
It also demonstrates how global commodity markets can respond to regional shortages without requiring producers and consumers to be located close to one another.
Europe competes for Asian fuel
The increase in European purchases from South Korea also means European buyers are competing with other Asian consumers for available cargoes.
That competition can influence regional fuel prices.
If Europe continues paying a premium, more Asian cargoes could be redirected westward.
If the European premium narrows, some suppliers may prefer to keep their products in Asia.
The resulting trade flows will depend on fuel prices, freight costs, refinery utilisation and expectations about demand.
Airlines face higher operating costs
Jet fuel is one of the largest operating expenses for airlines.
A sustained increase in fuel prices can therefore raise airline costs and put pressure on profit margins.
Airlines can attempt to manage the effect through fuel hedging, fare adjustments, route changes and operational efficiencies.
But these measures do not completely eliminate exposure to the market.
TUI, Europe’s largest tour operator, said on September 22 that geopolitical tensions in the Middle East had increased jet-fuel prices and affected customer booking patterns. The company has been using fuel hedging and other cost measures to manage the impact.
Higher fuel costs can affect airfares
When airlines face higher fuel costs for an extended period, some of the additional expense can eventually be reflected in ticket prices.
The timing and size of any increase varies by airline and route.
Competition, ticket demand, existing fuel hedges and other operating costs can influence whether airlines immediately pass higher costs to passengers.
A tight jet-fuel market therefore does not automatically mean that airfares will rise by a specific amount.
It does, however, increase one of the major cost pressures facing airlines.
European aviation has already faced fuel concerns
The current pressure follows months of uncertainty over Europe’s jet-fuel supply.
Reuters reported in July that European inventories had fallen sharply and that the region had been relying on imports from the United States and Asia, increased refinery output and stock withdrawals to keep aviation fuel supplies available.
That earlier supply response helped prevent the market from running out of fuel.
The latest forecast suggests that maintaining adequate supply could become more difficult if Middle Eastern disruptions continue into the fourth quarter.
Refineries have limited room to respond
European refiners can increase production of jet fuel to some extent, but their ability to compensate for lost imports is limited.
Refineries produce several petroleum products simultaneously.
Increasing jet-fuel production can affect the output of diesel, gasoline and other products depending on the refinery configuration and available crude feedstock.
The broader refining market is already tight.
The IEA reported that global refinery crude throughputs in July remained almost 5 million barrels per day below the same month a year earlier, while refining margins rose sharply because of tight middle-distillate markets.
That limits the industry’s ability to quickly create large amounts of additional refined-product supply.
Diesel shortage adds pressure
Jet fuel is not the only refined product facing tight conditions.
Diesel markets have also been under severe pressure.
Reuters reported on September 21 that global diesel prices had reached record levels as disruptions involving Iran, Ukraine, Russia, Saudi Arabia and the United Arab Emirates reduced supplies.
Jet fuel and diesel belong to the middle-distillate category.
This means that competition for refinery capacity can affect both markets.
A refinery facing strong diesel demand and high margins may have less flexibility to increase jet-fuel output without affecting its broader product mix.
Middle Eastern exports remain critical
The scale of Europe’s potential deficit reflects how dependent the global fuel system remains on a relatively interconnected network of refineries and shipping routes.
The loss of Middle Eastern refined-product exports cannot easily be replaced by one producer.
Instead, supply must be assembled from several regions, including Asia, North America and European refineries.
That increases transportation distances and can make the market more sensitive to freight rates and shipping disruptions.
China provides additional supply
China has also increased its refined-fuel exports.
Chinese exports of refined petroleum products reached 6.01 million tonnes in August, up 12.7% from a year earlier, according to Reuters. Jet-fuel exports reached a record 2.55 million tonnes, an increase of 41.4% year on year.
The increase followed Beijing’s decision to ease some export restrictions introduced earlier in the year to protect domestic supplies.
Chinese jet fuel can therefore provide additional international supply at a time when Europe needs alternative sources.
However, China’s overall refined-fuel exports for January through August remained below the previous year’s level.
Europe’s supply gap is a forecast
The projected 510,000-barrel-per-day deficit should be interpreted carefully.
It is a forecast based on expected supply and demand conditions, not a measurement of an existing physical shortage of that exact size.
Actual market conditions can change rapidly.
An increase in European refinery output, additional imports from Asia or North America, a decline in aviation demand or an improvement in Middle Eastern shipping could reduce the projected deficit.
A further disruption could increase it.
Oil prices remain volatile
The jet-fuel situation is closely connected to wider crude-oil market conditions.
Oil prices have experienced substantial volatility during the conflict because traders are continually reassessing the risk to production, exports and shipping.
Reuters reported that crude prices fell on September 22 as some Middle Eastern oil flows improved and hopes of diplomacy between the United States and Iran increased.
Lower crude prices can reduce the cost of producing jet fuel.
But refined-product availability depends on more than the price of crude.
A refinery needs access to feedstock, operational capacity, transport infrastructure and a functioning market for exporting the finished product.
Shipping remains a key variable
The availability of shipping capacity will be another important factor.
Long-distance deliveries from Asia require vessels to travel much farther than shipments from traditional European suppliers.
Freight rates, insurance costs and geopolitical risks can therefore influence whether additional cargoes are economically viable.
If shipping disruptions increase, the ability of European buyers to compensate for lost regional supplies could become more difficult.
Airlines are adjusting operations
Airlines and travel companies are already responding to the uncertainty.
TUI said geopolitical tensions had caused customers to delay some travel decisions, while the company restricted certain flight availability and implemented cost-cutting measures.
The impact on individual airlines will vary.
Carriers with strong fuel-hedging programmes may be partially protected from short-term price increases.
Airlines without comparable protection may experience the impact more quickly.
Demand could provide some relief
A potential counterweight to the supply problem is demand.
Higher fuel prices can reduce demand if airlines cut capacity, passengers postpone travel or businesses reduce flying.
Economic weakness can have a similar effect.
The IEA has already projected a decline in global oil demand in 2026, partly because the prolonged disruption and elevated fuel prices have reduced consumption.
If European aviation demand weakens sufficiently, the region’s jet-fuel deficit could be smaller than current projections suggest.
Europe may need more imports
The most immediate solution to the projected shortfall is likely to involve additional imports.
South Korea has already demonstrated that it can supply substantial volumes.
China and other Asian refiners could potentially contribute more cargoes if economics and government policies permit.
North American refineries could also supply Europe, although transportation costs and competing domestic or regional demand would influence the volume available.
Strategic fuel management becomes more important
The current situation also highlights the importance of fuel inventories.
Large stocks can provide a buffer when imports are disrupted.
But when inventories fall to unusually low levels, even a relatively modest supply interruption can have a larger effect on prices.
European governments, refiners, traders and airlines therefore have an interest in monitoring stocks as closely as possible.
The ARA inventory decline is particularly significant because it provides an indication of how much readily accessible fuel is available in one of Europe’s key trading hubs.
The fourth quarter will be critical
The October-to-December period will determine whether the projected supply deficit materialises at the scale currently expected.
Several variables could change the outcome.
Middle Eastern shipping could improve.
European refineries could increase production.
Asian exporters could send additional cargoes.
Airline demand could weaken.
Alternatively, another disruption could further reduce supply.
The market is therefore likely to remain highly sensitive to geopolitical developments.
Potential implications for African aviation
European fuel-market conditions can also matter for African aviation.
Many flights between Africa and Europe are operated by European, African and Middle Eastern carriers that purchase fuel in interconnected international markets.
Higher jet-fuel costs can increase operating expenses for airlines serving African destinations.
The impact on African ticket prices and flight schedules would vary by carrier, route and fuel-hedging arrangements.
Countries that depend heavily on international aviation could therefore feel some of the effects of the European fuel squeeze even if their domestic fuel supplies remain adequate.
Nigeria could also be affected indirectly
Nigeria’s aviation sector is similarly exposed to global jet-fuel market conditions.
The country is a significant oil producer, but aviation fuel prices are influenced by international crude and refined-product markets as well as domestic refining, distribution and supply conditions.
Greater competition for globally traded jet fuel can affect import economics and the cost of aviation operations.
Nigeria’s expanding domestic refining capacity could provide some additional supply resilience, but international market prices remain relevant to the economics of petroleum products.
Europe faces a supply challenge, not necessarily a shutdown
The projected European deficit should not be interpreted as an imminent grounding of the continent’s airline industry.
Europe has multiple sources of supply and has already demonstrated an ability to redirect imports from distant producers.
The concern is that replacing lost Middle Eastern supply requires higher-cost and longer-distance trade flows while regional inventories are already low.
That makes the market more vulnerable to another disruption.
What happens next
The direction of the European jet-fuel market will depend heavily on the Middle East.
A sustained improvement in shipping through the Strait of Hormuz could restore some supplies and reduce pressure on European inventories.
A prolonged disruption would increase the need for imports from Asia and other regions.
Airlines will also continue to adjust their fuel purchases, hedging strategies and flight plans according to market conditions.
A global market under pressure
Europe’s projected fourth-quarter jet-fuel deficit illustrates the wider consequences of disruptions to global energy trade.
A regional conflict can reduce refinery output and shipping flows thousands of kilometres away, forcing buyers to compete for alternative supplies.
South Korea’s increased exports and China’s record August jet-fuel shipments show how the global market can respond.
But the European market is entering the final quarter with inventories already depleted and refining capacity under pressure.
The coming months will therefore test how effectively international fuel markets can redirect supplies while geopolitical uncertainty continues.
For European airlines and passengers, the immediate issue is not simply whether fuel exists, but how much it costs and whether sufficient supplies can reach the continent when they are needed.
