Europe's fuel crisis fuels oil stock rally of up to 87% in 2026

Europe's renewed fuel crisis has turned into an unexpected profit windfall for parts of the continent's energy industry, even as motorists grapple with record prices at filling stations.

The driving force isn't crude oil prices themselves but what happens inside refineries. Shortages of diesel, petrol and jet fuel have pushed the so-called crack spread — the gap between crude oil prices and the price of refined fuels — to record levels.

Why refining margins have surged

Global supply of refined fuel has been disrupted from two directions. The conflict around Iran and the Strait of Hormuz has cut diesel and jet fuel exports from Gulf refineries, while Russia banned diesel exports this summer following Ukrainian drone attacks on its refineries, further tightening a market Europe depends on. The European diesel crack spread has nearly doubled since November 2025.

The European Central Bank has taken notice. Speaking after the ECB raised interest rates on 10 September, President Christine Lagarde said that six months ago few people knew what refining margins were, but now everyone does, calling diesel "yet another bottleneck". The ECB reported energy inflation rose to 14.3% in August from 10.3% in July, with the diesel margin now accounting for about 41 cents of every litre sold at the pump.

The ten biggest gainers

Against this backdrop, European oil and gas stocks have become some of the market's strongest performers. Among companies with market capitalisations of at least €10 billion, based on data through 23 September, Spain's Repsol leads with an 87.2% gain, followed by Finland's Neste (+76.4%) and Norway's Equinor (+67.9%). The list also includes Vår Energi, Orlen, Romgaz, Galp, OMV, Eni and TotalEnergies, with gains ranging from 40% to 56% since January. Several of these companies have already reported sharply higher profits compared with a year earlier, with third-quarter results due from late October through November.
