Belgian Diesel Price Falls After Record High Above €2.50
Belgium’s maximum price for diesel (B7) will fall by 9.6 cents to 2.405 euros per liter on Thursday, easing the burden on motorists and businesses one day after the fuel broke the symbolic 2.5-euro threshold for the first time. The federal economy ministry (FOD Economie) published the new tariff, effective 24 September, according to VRT NWS, which reported the drop would bring relief after days of record pump prices.
The decline follows an all-time high of 2.501 euros per liter set on Tuesday, when diesel surpassed the previous record of 2.489 euros reached in April. The adjustment stems from falling international oil prices, which have declined for six consecutive trading days — the longest losing streak since August 2025.
A Record Driven by War
The surge that pushed Belgian diesel above 2.5 euros was driven by the war in the Middle East, where the United States and Israel are fighting Iran. According to VRT NWS analysis, the escalation in the Persian Gulf and the continuing attacks on tankers in the Strait of Hormuz have kept crude prices high, while Ukrainian drone strikes on Russian refineries have removed a key diesel exporter from global markets.
The supply shock was compounded on 13 September, when a drone attack — attributed to pro-Iranian militias in Iraq — disabled Saudi Arabia’s strategic east–west pipeline. The pipeline, which normally carries about 3 percent of global oil supply, had become critical as a means of bypassing the blocked Strait of Hormuz. “The scarcity grows every day,” said Thijs Van de Graaf, professor of energy politics at Ghent University, in a VRT report.
Prices Ease on Diplomacy and a Restarted Pipeline
Relief came from two developments. Saudi Arabia is restarting the damaged pipeline, easing one of the most acute supply bottlenecks. Separately, US President Donald Trump said American officials had held “very productive” talks with Iranian representatives, raising hopes of de-escalation.
Brent crude fell toward 98 dollars per barrel and US WTI toward 89 dollars, HLN reported. Still, oil remains roughly 60 percent more expensive than before the US-Israel war against Iran began — a reminder that the decline is market-driven relief rather than a structural reversal.
No Change for Petrol, Heating Oil Cheaper
Petrol prices are unchanged in this adjustment: Petrol 95 (E10) remains capped at 2.058 euros per liter and Petrol 98 (E5) at 2.234 euros. Heating oil (mazout) also becomes cheaper under the same adjustment, the FOD Economie’s official tariff page confirms, listing tariff no. 2026/184 as valid from 24 September.
A Fragile Relief
The good news is best understood against the extraordinary run-up. Diesel is still about 44.8 percent more expensive than a year ago, and researcher Marten Ovaere of Ghent University cautioned that the “record” framing has limits. “In euros, diesel was never this expensive. But adjusting for inflation, diesel was even more expensive in March 2022 — the equivalent of 2.69 euros per liter,” he told VRT. He added that electrification has softened the blow: “Whoever drives electric barely notices this price rise.”
The wider cost of living has felt the squeeze beyond the pump. In its note published on 10 September, the federal energy regulator CREG confirmed that social energy tariffs for the fourth quarter would rise by an average of 7 percent for electricity and 11.4 percent for gas, citing higher wholesale energy prices. Flemish households taking out new energy contracts in September faced estimated annual bills of about 1,378 euros for electricity and 1,898 euros for gas — the highest in years.
Pressure on the Government
The price spike has thrust fuel policy into Belgium’s budget debate. In parliament’s energy committee, Energy Minister Mathieu Bihet (MR) said “the state does not get richer from rising energy prices,” noting the government had collected just over 100 million euros in extra fuel excise — money his party wants to return to citizens through an “inverse cliquet” mechanism that would cut excises once prices cross a threshold.
Opposition PS president Paul Magnette demanded that the government reverse the excise increase on gas and heating oil and provide temporary support funded from oil companies’ excess profits, warning that “otherwise people will soon have to pay to go to work.” Unions have threatened harder action: the socialist Métallos FGTB in Wallonia demanded immediate excise cuts, and a demonstration is planned for 9 October, with a possible general strike in the week of 23 November.
Businesses are also feeling the strain. Construction federation Bouwunie is lobbying for a temporary refund of diesel excise for light commercial vehicles. “If a company has five diesel vans, refuelling with current prices costs about 900 euros a month more than in March,” said Twain De Hondt, its director of studies. If the situation persists, he warned, extra costs could exceed 10,000 euros a year.
Europe Weighs Its Options
Belgium is not alone in responding to expensive fuel. Germany agreed to cut petrol and diesel excise by 17 cents per liter from early October through year-end, alongside a maximum price. France announced a 450-million-euro support package, extended a commuter bonus and raised company fuel allowances. Italy suspended road tax for 2027 on low-powered vehicles, and Slovak Prime Minister Robert Fico called for an emergency EU summit.
Some economists caution against broad relief. “General measures that hit everyone — including people who don’t need them — are false economy,” French Finance Minister Roland Lescure said, “because we will ultimately have to pay for them.” Professor-emeritus Stefaan Proost of KU Leuven made a similar point for Belgium: “Taking general measures does not seem necessary to me,” he told VRT, noting that Belgium’s automatic wage indexation already cushions workers in a way neighbouring countries’ systems do not.
What to Watch
The immediate question is whether the decline holds. Trump has floated a ban on US diesel exports — a move that would hit Europe hard, since the US became a critical supplier after the Middle East and after Russia’s war on Ukraine curtailed Russian supply.
Whether the easing becomes a trend or a pause depends largely on forces outside Belgium’s control: the durability of US-Iran talks, the restart of Saudi Arabia’s pipeline, and the trajectory of the wider conflict. As VRT energy specialist Denny Baert put it, as long as there is no hard deal, “energy prices remain volatile, reacting to the news of the day — and above all high.”
For Belgian drivers, Thursday brings welcome relief at the pump. But with prices still far above pre-war levels and winter approaching, the broader energy crunch is far from over.
