Why Fuel Prices Are Surging Across Europe in 2026 — and When They Might Fall Again

As of the week of 2026-09-14, the EU averaged €2.075 per litre of diesel and €1.924 for petrol in our figures — the highest readings in a European price series that reaches back two decades. Diesel alone is up 23% since late June, has overtaken petrol in 23 of 27 EU countries, and has pushed past its previous record of €1.999 set back in 2022.

This is not one shock but several arriving at once. A widening war in the Middle East and a Ukrainian drone campaign against Russian refineries have squeezed the world's diesel supply from two directions; refining margins have hit record highs; a low Rhine has made barge transport in Germany dearer; and Europe is heading into winter with its gas stores unusually empty. None of these is going away next week, which is why we are treating this as a living report and updating it as the picture changes.

Below: the numbers first, then the six forces behind them, what governments across Europe have announced, and what it all means for the tank in your driveway.

Across the EU-27, the average pump price in the week of 2026-09-14 was:

• Diesel: €2.075/L — up from €1.689 at the end of June, a rise of 23%.
• Petrol: €1.924/L — up from €1.717, a rise of 12%.

Diesel has done something unusual: it now costs more than petrol in 23 of 27 EU countries, by about 15 cents on average, reversing the normal order in which diesel is the cheaper fuel. Filling a 50-litre tank with diesel now costs around €104, roughly €19 more than at midsummer.

The pain is spread unevenly. In the biggest markets diesel stood at €2.426 in Germany (up 38% since June), €2.291 in France, €2.191 in Italy, €2.197 in Austria and €2.494 in the Netherlands, while Spain, at €1.834, remained one of the cheaper large markets. Poland shows the steepest climb of the group — diesel there rose 42% since June to €2.005 as earlier tax cuts unwound.

One caveat on the averages: ours are simple (unweighted) means across EU members, so they read slightly lower than the European Commission's consumption-weighted series. The direction and the size of the move are the same in both.

Official statistics confirm the scale. Eurostat's figures for August show fuel prices across the EU up 23.8% year on year, with 26 of the 27 member states higher and 18 of them above 20%; diesel alone climbed 8.3% in that single month against 3.3% for petrol. The steepest annual rises came in Bulgaria, Lithuania, Finland, Germany and France. At the other end sits Hungary, up just 1.3% — a visible effect of its price cap.

The single biggest reason diesel is rising faster than petrol is that the fuel is being choked off from two directions at once.

The Middle East. Fighting between the United States and Iran in and around the Strait of Hormuz — the channel that normally carries about a fifth of the world's seaborne oil — drove Brent crude from around $72 a barrel before the war to a peak above $126. After a drone attack on 13 September shut Saudi Arabia's East-West pipeline, the kingdom's main route around Hormuz, Saudi Aramco reportedly told at least two European refiners they would receive no crude under long-term contracts in October, according to Bloomberg. On 22 September came the first signs of easing: Saudi Arabia restarted the pipeline, at a low rate to begin with (it normally carries around four million barrels a day, about 4% of world supply, and full capacity may take weeks), and a senior Iranian official said Tehran would reopen Hormuz within seven days if Washington eased its blockade of Iranian ports. Brent fell back below $100, to around $98.

Russia. At the same time, Ukraine has been striking Russian refineries with long-range drones — on the International Energy Agency's count, roughly one successful hit every three days over the first eight months of 2026, with a record 21 strikes in August alone that pushed Russian refining to its lowest level in more than two decades. Three of Russia's six largest diesel refineries have been knocked out or throttled, and diesel output has fallen by roughly a quarter to a third. On 8 July Moscow banned diesel exports outright to protect its home market; the ban now runs to 30 September, and an extension to the end of October has already been signalled. Before the strikes Russia supplied about a tenth of the world's diesel. Industry estimates put the combined loss at roughly two million barrels a day of Russian product and a similar amount from the Middle East.

More OPEC+ oil has not filled the gap. The group finished unwinding its voluntary production cuts over the summer, but with war disrupting actual exports those increases have made little difference to physical supply. Diesel — the fuel of trucks, tractors and heating — is simply harder to find than it has been in years.

Even where crude is available, turning it into diesel has become extraordinarily profitable — a sign of scarcity, not of gouging. The refining margin for diesel, the gap between crude and finished fuel, topped $100 a barrel for the first time in history in August, against a normal $20-40. European refiners have switched from making jet fuel to making diesel to chase it, and analysts cited by Euronews expect the diesel margin to peak only in October. That margin now accounts for around 19% of the diesel pump price against 8% for petrol — which is precisely why diesel has outrun petrol.

The Rhine adds a German twist. In mid-August the gauge at Kaub, the river's key chokepoint, fell into single digits for the first time on record — below even the 25 cm low of 2018 — so barges that carry diesel and heating oil inland could only sail part-loaded. Rain has since lifted the level to around 60 cm, but forecasts keep the river below its 77 cm low-water mark through the end of September, and the federal hydrology institute expects no real easing before early October. Tanker freight from Rotterdam to Karlsruhe has climbed to €60-70 a tonne, up from about €45 in late June. That is a big part of why German diesel, at €2.426, sits well above the EU average.

The exchange rate quietly makes it worse. Oil is priced in dollars, and with the euro around $1.14 every dollar of crude costs Europeans more than it does Americans. By the European Central Bank's own rule of thumb, each sustained $10 rise in oil adds about half a percentage point to euro-area inflation — so this is a fuel story that is also becoming an inflation story.

The surge is not only at the pump. Europe's gas stores, the buffer for winter heating and power, are unusually low: about 69% full in mid-September against a seasonal norm near 88%, which is why member states quietly cut this year's fill target to 80% from the traditional 90%. The Dutch TTF gas benchmark has climbed above €68 a megawatt-hour, its highest since early 2023.

Because gas-fired plants set the electricity price in most hours, that feeds straight through to power. In our own wholesale data the German day-ahead price averaged €141/MWh in September against €106 in July — a 33% jump — with one September hour spiking to €740. France rose about 40% and the Netherlands about 43% over the same stretch. Households will not feel all of this at once, because retail tariffs lag the market, but a cold snap before storage recovers would be felt quickly. You can watch the hourly moves on our wholesale electricity pages.

With prices at records, governments have reached for the tax lever — and pressure is now building on Brussels too.

• Germany: the cabinet formally approved a cut in energy tax of 14 cents a litre — about 17 cents once lower VAT is counted — on 22 September, to run from 1 October to 31 December, with the Bundestag and Bundesrat expected to pass it the same week. It is the second such rebate of 2026 after a May-June round; the €2.5 billion cost is split between the federal government and the states, and the Bundeskartellamt is watching whether the full discount actually reaches the pump. A separate price cap, modelled on Belgium and Luxembourg, is planned for 1 January at the latest but not yet designed. (Germany's ADAC motoring club put national diesel near €2.47 in mid-September.)
• Czechia goes furthest: from 1 October it caps station margins at about 10 cents a litre, cuts diesel excise from roughly 41 to 33 cents, imposes a 50% levy on refiners' extra margins for 2026 and 2027, and publishes daily maximum prices.
• France has extended sector-specific diesel rebates — 35 cents a litre for fishermen, 20 for public-works vehicles, 15 for farmers — through the end of the year.
• Italy cut diesel by 12.2 cents a litre for the second half of September, tapering to 6.1 cents into early October, and moved to scrap road tax on smaller cars.
• Spain applied a 20-cent diesel discount, and Poland cut fuel VAT from 23% to 8%. Hungary is paying €55 per family diesel car. More than a dozen member states now have some relief in place.

At EU level the tone has shifted from advice to demands. French President Emmanuel Macron wrote to Commission President Ursula von der Leyen on 18 September asking for emergency exemptions from EU fuel-quality specifications — density and desulphurisation rules he says could lift output by 5-20% — plus higher biofuel blending in diesel and a one-year delay to the methane regulation due in January 2027; the Commission said on 22 September it is examining the request. EU finance ministers, meeting in Dublin, have also urged Brussels to propose a windfall tax on oil companies' profits. So far the Commission has encouraged national tax relief where it is affordable while stressing that it cannot set the world oil price. The common thread across all of it: almost every measure targets diesel, the fuel doing the most damage to household and business budgets.

For a typical driver the €19 added to a diesel fill since June is the visible cost; for hauliers, farmers and anyone who heats with oil, the same move lands many times over. Two practical points follow from the data.

First, the diesel-over-petrol reversal changes the old advice. For years a diesel car was the cheaper long-distance choice; with diesel now 15 cents above petrol in most of the EU, that gap has narrowed or flipped. If you are choosing between two cars, or two rental options, run today's numbers rather than yesterday's habit.

Second, the spread between countries and between stations is unusually wide right now, so shopping around pays more than usual. Our tools are built for exactly this: the European fuel price ranking shows where each country stands today, the country pages such as Germany, France and Italy map live station prices near you, and our traveller's fuel guide covers cross-border tips for a continent where a short detour can save real money.

Nobody can promise a date, but the data points to what to watch.

• Refining margins are expected to peak around October; once refiners catch up with demand the diesel premium should ease, even if crude stays high.
• The Rhine should refill with autumn rain — though not, on current forecasts, before early October — which would take one cost out of German prices.
• Gas storage is the winter wildcard: a mild winter lets Europe coast on 69% stores; a cold one would pull on power prices and, indirectly, on refining costs.
• The wars remain the biggest unknown, and here the first tentative signs of easing appeared on 22 September: Saudi Arabia restarted its East-West pipeline and Iran offered to reopen Hormuz within seven days if the US eases its blockade, which pushed Brent back below $100. Treat this as a signal, not a turn — a ceasefire agreed in April collapsed again in July. A halt to strikes on Russian refineries would bring the other half of the relief.

Two dates to watch in the coming days: Russia's diesel-export ban expires on 30 September (an extension is already signalled), and Germany's and Czechia's relief measures start on 1 October.

Our best read as of the latest update: the sharpest phase of the diesel spike is probably near its peak, and the first de-escalation signals point the right way, but a return to spring's price levels depends on the geopolitics, not the calendar. We will revise this section as the evidence changes.
