Europe’s Fuel Supply Is Facing a Costly Bottleneck That Cheaper Oil May Not Fix

European wholesale diesel prices reached about $220 a barrel in September, nearly double crude oil prices, according to the International Energy Agency (IEA).

The premium for diesel over crude narrowed from roughly $100 to $60 a barrel by early October as record tanker freight rates increased the cost of supplying European refineries.

Global oil production rose by 2.5 million barrels a day in September to 102.3 million barrels a day.

Middle Eastern exports of refined petroleum products remained at 1.9 million barrels a day, against 4.7 million before the war.

Worldwide diesel exports were nearly 700,000 barrels a day lower than a year earlier, following disruptions to Russian and Middle Eastern supplies.

European importers must secure replacement diesel cargoes while freight costs remain elevated.

The IEA expects diesel markets to stay tight into 2027 and inventories to recover only gradually, potentially extending Europe’s reliance on imported supplies through the winter.

Higher Crude Costs Threaten Europe’s Refinery Output

Northwest European refining margins fell from about $54 a barrel in early September to a loss of $11 by October 5, before recovering to roughly $3.

Higher crude-delivery costs and weaker returns on gasoline, naphtha and fuel oil eroded earnings from processing crude, despite elevated diesel and jet-fuel prices.

Europe’s refining capacity has declined by about 20% since 2009, with 35 facilities closed, according to FuelsEurope.

At the end of 2025, the European Union, Britain, Norway and Switzerland had 72 mainstream refineries with combined annual capacity of 625.4 million tonnes.

High tanker costs have discouraged shipments of some crude grades from the Americas.

Reuters reported on October 12 that U.S. refineries were operating near their highest rates in 28 years, while access to discounted regional crude supported North American refining margins.

European refiners seeking replacement feedstock must also account for transatlantic freight costs.

The IEA warned in October that further deterioration in refining margins could lead less competitive plants in Europe and Asia to reduce processing rates.

The risk is greatest for facilities unable to secure crude at prices that justify continued operation.

Europe’s Diesel Imports Face a Winter Supply Test

Diesel imports from outside the European Union were equivalent to about 18% of consumption in the first half of 2026, according to the Centre for Eastern Studies (OSW).

Persian Gulf countries supplied roughly 40% of those imports, with Saudi Arabia accounting for more than one-third. The United States ranked second among external suppliers.

Saudi diesel shipments to Europe fell by more than 40% in September from August following damage to Gulf oil infrastructure, OSW reported.

European importers seeking replacement cargoes from the United States, India and other suppliers face higher transport costs and competition for available shipments.

At the Amsterdam-Rotterdam-Antwerp trading hub, independently held gasoil inventories averaged 13.32 million barrels in early October, up 6% from September, according to Insights Global data reported by ENGINE.

The European Commission said on September 29 that commercial stocks at the hub remained below their five-year average, although EU fuel supplies were stable and refineries were operating near maximum capacity.

Reuters reported on October 1 that Washington had pressed France and Germany to release emergency diesel stocks, warning that it could restrict American exports if they refused.

The two countries hold more than one-third of the EU’s strategic diesel reserves. Any release would provide additional near-term supply, with the volume and timing dependent on government decisions.

Europe’s Diesel Price Recovery Depends on Rebuilding Inventories

Global refinery throughput is forecast to rise from 81.3 million barrels a day in October to 84.6 million by December, according to the International Energy Agency (IEA).

The agency expects average processing volumes to increase by 2.8 million barrels a day in 2027, following a decline of 2.3 million this year.

Higher refinery output is expected to return the global diesel and gasoil market to a quarterly surplus in early 2027.

The IEA forecasts a seasonal increase in stocks, although the additional supply will not replace the inventory losses accumulated during 2026.

Replenishment beyond normal seasonal changes is considered unlikely before the second half of 2027.

Russia’s easing of diesel export restrictions is unlikely to bring substantial additional supplies to international markets.

The IEA attributes the constraint to damaged refining capacity. China has resumed issuing petroleum-product export licences, easing concerns about shipments from its refiners.

The pace of recovery in Middle Eastern refined-product exports remains central to the agency’s 2027 supply outlook.

Shipping costs present a further obstacle. Reuters reported on October 19 that freight and insurance charges were absorbing much of the gross refining margins earned by Asian operators dependent on Middle Eastern crude.

The disruption has raised the cost of moving oil out of the Gulf, complicating the recovery of refinery operations and international fuel trade.

Europe’s Fuel Outlook Now Depends on Russia Diplomacy

Russian President Vladimir Putin has proposed a November meeting with Donald Trump and China’s Xi Jinping to discuss ending the war in Ukraine, The Wall Street Journal reported, citing people familiar with the discussions.

Ukrainian President Volodymyr Zelensky would be excluded from the proposed talks, which Trump has yet to accept.

Washington has already moved to facilitate some Russian oil and diesel transactions.

A broader agreement with Moscow could bring additional Russian petroleum products into international trade, although restrictions imposed by the European Union would remain in force unless European governments agreed to change them.

That leaves European leaders with a decision extending beyond fuel prices. Any proposal to reopen direct energy trade with Russia would have to confront the terms of a settlement, Ukraine’s position and Europe’s security commitments.

A Washington–Moscow agreement alone would not determine when Russian diesel could return to European markets.
