Fuel Prices in Belgium Set to Drop Significantly on Friday
Belgian motorists can expect welcome relief at the pump starting Friday, May 29, as the Federal Public Service for Economy (FOD Economie) has announced a sharp reduction in maximum fuel prices. Petrol 95 (E10) will drop by 11.8 eurocents to €1.856 per liter, while diesel (B7) will fall by 10.3 eurocents to €2.038 per liter — one of the largest single-day declines in recent months, according to Het Laatste Nieuws.
Why Prices Are Falling
The price reduction is directly linked to renewed optimism about a potential peace agreement between the United States and Iran that could reopen the strategically vital Strait of Hormuz. The strait, through which approximately 20% of global oil passes, has been effectively closed since late February 2026 due to the US-Iran conflict.
Iranian state television recently reported viewing a draft agreement that would include reopening the waterway, sending international oil prices tumbling. Brent crude fell below $95 per barrel on May 27 — the first time in a month below that threshold — while US WTI crude dropped nearly 6% to around $88 per barrel, as reported by VRT NWS.
New Maximum Prices at a Glance
The official tariff published by FOD Economie (Tariff No. 2026/101, valid from May 29) sets the following maximum prices:
| Fuel Type | New Max Price (€/L, incl. VAT) | Price Drop |
|---|---|---|
| Petrol 95 (E10) | €1.856 | -11.8 eurocents |
| Petrol 98 (E5) | €1.938 | -10.7 eurocents |
| Diesel (B7) | €2.038 | -10.3 eurocents |
The new prices are confirmed by BRAFCO, the Belgian Federation of Fuel Traders, and CARBU.com.
For a typical 50-liter tank, this represents a saving of approximately €5.90 for petrol and €5.15 for diesel compared to the previous day’s prices.
Context: A Volatile Journey
Fuel prices in Belgium have experienced extreme volatility since the outbreak of the US-Iran conflict in late February 2026. Diesel reached a record high of €2.489 per liter in early April, while petrol 95 (E10) crossed the €2.00 mark on May 19 for the first time since July 2022.
Since early May, prices have been on a gradual downward trend amid fluctuating hopes for a diplomatic resolution. The May 7 reduction saw diesel drop 9.4 cents, followed by further declines on May 15 and May 21. However, the market remains highly sensitive to geopolitical developments — new US attacks on Iran on May 27 caused temporary price spikes, underscoring the fragility of the current optimism.
How Belgium’s Fuel Pricing Works
Belgium operates a unique maximum price system for petroleum products, administered by FOD Economie. The government sets a legal ceiling for each fuel type based on international oil product and biocomponent quotations, quarterly indexation of strategic petroleum stock management contributions (ASEVA), semi-annual indexation of distribution margins, plus VAT and excise duties. This system protects consumers from excessive price spikes, unlike many neighboring countries where prices are fully market-driven.
What This Means for Motorists
Experts advise drivers to delay refueling until Friday to benefit from the lower prices. However, the situation remains highly volatile. While a finalized US-Iran peace deal could drive prices further down toward pre-conflict levels — petrol 95 was around €1.60–€1.70 in early 2026 — renewed hostilities could quickly reverse the current trend.
Broader Economic Implications
The drop in fuel prices comes at a critical time for Belgian consumers. Inflation surged to 4.01% in April, driven largely by energy costs. Lower fuel prices could help bring inflation back toward target levels and provide relief to households that have faced months of rising costs. The federal government previously approved €80 million in energy support measures in April, including tax incentives for commuting mileage allowances and €15 million for social heating oil and gas funds.
Looking Ahead
All eyes remain on the US-Iran negotiations. If a peace deal is finalized and the Strait of Hormuz reopens, further price reductions are likely. However, even after a potential agreement, energy markets may retain a higher risk premium given the demonstrated vulnerability of this critical maritime chokepoint. For now, Belgian motorists can enjoy a rare moment of good news at the pump — but the underlying volatility serves as a reminder that the energy crisis is far from over.
