Fuel Prices Rise Again in Belgium This Friday

Belgian motorists face another increase at the pump this Friday, July 3, as the Federal Public Service for Economy (SPF Economie) announced new maximum fuel prices on Thursday. The hike comes just two days after a minor increase on Tuesday, reversing a period of declining prices and adding to the cost-of-living pressures on households and businesses across the country.

According to La Libre Belgique, the price of gasoline 95 (E10) will rise by 3.9 cents per liter, bringing the new maximum price to €1.85 per liter. The increase is steeper for gasoline 98 (E5), which will go up by 7.2 cents per liter to a maximum of €1.964 per liter. For a typical 50-liter tank of E10, this represents an additional €1.95 per fill-up.

Context: A Volatile Energy Market

The latest increase is driven by volatility in global oil markets, which have been heavily impacted by the ongoing Middle East conflict. As L’Avenir reports, fuel prices had risen sharply since early March due to the war in the Middle East, before declining significantly in recent weeks. That downward trend has now reversed.

The 2026 Iran War, which began on February 28, saw Iran effectively close the Strait of Hormuz, a critical chokepoint for global oil shipments. This sent oil prices skyrocketing and has kept energy markets volatile through mid-2026.

How Belgian Fuel Pricing Works

Belgium operates a system of maximum authorized prices for gasoline, diesel, and heating oil, calculated by the SPF Economie. The maximum price is determined by the evolution of petroleum product prices on international wholesale markets over a specific period, with thresholds that must be crossed to trigger an adjustment. A correction factor known as the “K Factor” (Facteur K) smooths fuel prices over time through a complex calculation designed to dampen volatility.

However, this system has come under increasing criticism. According to an RTBF investigation from March 2026, the petroleum sector argues that maximum prices are “significantly lower than real prices,” forcing retailers to buy products at prices exceeding the maximum selling price. Brafco, the Belgian federation of fuel traders, is calling for indicative rather than mandatory maximum prices, which would allow retailers to set their own prices based on actual acquisition costs. If such a system existed today, Belgian pump prices would be comparable to those in the Netherlands or Germany — significantly higher.

Belgium in the European Context

Despite the increases, Belgium’s fuel prices remain mid-range compared to its European neighbors. According to data from fuel-prices.eu, as of June 22, 2026, Belgian petrol stood at €1.768 per liter (17th of 27 EU countries) and diesel at €1.860 per liter (22nd of 27). The EU average was €1.728 for petrol and €1.713 for diesel.

Belgium remains cheaper than France (€1.952/L petrol), Germany (€1.870/L), and the Netherlands (€2.206/L), but more expensive than Luxembourg (€1.648/L), where many Belgian drivers cross the border to fill up.

Broader Economic Implications

This increase adds to the cost-of-living pressures already weighing on Belgian households. The broader energy context shows that while current gas and electricity prices are significantly lower than during the 2022-2023 Ukraine crisis, the situation remains fluid. Consumer organization Testachats has urged the government to prepare contingency measures for vulnerable households, including extending the social tariff and heating vouchers.

What to Watch For

Several questions remain as the summer driving season approaches. Will the upward trend continue, or will prices stabilize? How will the ongoing Middle East conflict affect fuel prices in the coming months? And will the Belgian government modify the fuel pricing mechanism in response to sector pressure?

For now, Belgian motorists are advised to fill up before Friday to avoid the higher prices at the pump.
