Europe’s Diesel Prices Rise as Refining Capacity and Supplies Tighten

Europe’s diesel prices are rising amid tight global refined-fuel markets, reduced Russian refined-product output and disruptions to oil-product flows, while EU supply remains stable for now.

EU diesel prices rose 8.3% from July to August 2026. Fuel prices and lubricants for personal transport increased 23.8% from a year earlier in August.

The EU is not facing an immediate supply problem. Emergency stocks remain sufficient to respond to a market disruption, while European refineries are operating near maximum capacity. Demand is being met through higher refinery output and alternative global supplies.

The pressure reflects a long-term decline in European refining capacity as well as more recent disruptions. The EU, United Kingdom, Norway and Switzerland had 72 mainstream refineries with 625.4 million tonnes of annual primary capacity at the end of 2025. It also counts 35 refinery closures since 2009 and a 20% reduction in capacity. Those figures describe the industry’s capacity trend but do not establish that refinery closures directly caused the current price increase.

Diesel prices reflect crude costs, refinery margins, taxes, transportation and available inventories. Lower refining capacity can raise prices even when crude is available because crude must still be processed into diesel.

Russian refinery throughput fell to 3.8 million barrels per day in June, about 30% below the prior year. Russian diesel production was nearly 30% below 2025 levels by September. Russia introduced its first diesel-export ban on July 8 after Ukrainian attacks on its refineries intensified, and repairs to heavily damaged complex refinery units can take six to eight months on average.

The U.S. Treasury’s Office of Foreign Assets Control (OFAC) issued General License 135 on Oct. 9, authorizing transactions involving Russian-origin diesel, including delivery, offloading and imports into the United States, through 12:01 a.m. ET (04:01 UTC) April 7, 2027.

President Donald Trump announced that Russia would supply more than 300,000 tonnes of diesel immediately, 500,000 tonnes in November and 1 million tonnes afterward. The announced volumes are not confirmed deliveries. The license authorizes transactions but does not confirm that the cargoes have been delivered.

The commitments follow Trump’s earlier Russian diesel deal, which was announced as a way to add fuel to global markets while refining capacity remained tight.

Global oil-product flows are also facing instability around Middle Eastern shipping routes. The evidence does not establish that environmental policy alone caused current market conditions; the immediate pressure also reflects refinery attacks, export restrictions and tight global refined-fuel markets.
