OddsFrontEU petrol and diesel prices reach record highs as refining margins climb
European Commission data show unprecedented average pump prices, reviving demands for windfall taxation while officials say supplies remain secure for now.
New records at the pump
Average petrol and diesel prices across the European Union reached record highs in the week measured by the European Commission’s latest Oil Bulletin. Euronews calculated weighted averages of €2.063 per litre for petrol and €2.159 for diesel using prices reported for September 14. At those averages, filling a 50-litre tank costs roughly €103 with petrol and €108 with diesel, turning the energy shock into a direct household and transport expense.
The rise has been steep across 2026. Euronews reports that the weighted petrol average has increased by about 29% since the start of the year, while diesel has climbed almost 40%. National prices vary widely because taxes, duties, distribution costs and local market conditions differ. Petrol ranged from €1.34 per litre in Malta to €2.56 in Denmark, while diesel ranged from €1.21 in Malta to €2.51 in Finland.
Crude oil is only part of the increase
Conflict in the Middle East and disruption to energy flows have lifted crude prices, but refining costs are an increasingly important part of the pump price. Euronews says European Central Bank specialists estimated that refining margins accounted for €0.41 per litre of diesel and €0.17 per litre of petrol in the third week of September. Their futures-based assessment suggested petrol margins had already peaked in August, while diesel margins might not peak until October.
The Guardian reported renewed calls for an EU-wide windfall tax on energy companies as motorists and businesses absorb the increase. The policy debate remains unsettled. The European Commission’s AccelerateEU framework permits member states to tax windfall profits for social fairness and offers support for targeted national measures, but it does not itself impose a new bloc-wide levy. Governments must balance consumer relief against fiscal cost, market fragmentation and incentives to conserve fuel.
High prices without an immediate shortage
The Commission distinguishes the price crisis from a physical supply emergency. Its energy-crisis guidance says diversified oil and gas supplies, strategic reserves and additional import capacity mean there is no immediate EU security-of-supply concern for the winter of 2026–2027. It has nevertheless proposed a Fuel Observatory, closer coordination on storage and possible reserve releases, and temporary support for vulnerable households and exposed industries.
The next signals will come from weekly price data, diesel-refining margins and developments affecting international oil flows. A durable decline would probably require lower crude prices, restored refining capacity and more predictable shipping through disrupted regions. Until then, national tax relief, targeted income support and the windfall-profit debate will remain politically salient, even if Europe avoids an outright shortage.
