Fuel Prices Rise Again in Belgium Amid Iran Conflict

Belgian motorists face another increase at the pump as the Federal Public Service for Economy (FOD Economie) announced new maximum fuel prices effective June 3, 2026. Petrol 95 (E10) rises to €1.874 per liter, while diesel (B7) climbs to €2.08 per liter, adding to the cost-of-living pressures already weighing on Belgian consumers amid the ongoing US-Iran conflict.

New Price Increases

According to the FOD Economie, the latest adjustments under Tariff No. 2026/104 see petrol 95 (E10) rise by 1.8 cents to €1.874 per liter, petrol 98 (E5) increase by 1.5 cents to €1.953, and diesel (B7) jump by 4.2 cents to €2.08. The price changes result from quarterly indexation of ASEVA strategic oil reserve contributions, semi-annual adjustments to distribution margins, and fluctuations in international oil and biocomponent quotations.

These increases come just days after a significant drop on May 28-29, when petrol 95 fell 11.8 cents to €1.856 and diesel dropped 10.3 cents to €2.038, following hopes of a US-Iran peace deal. The yo-yo effect illustrates the extreme volatility gripping energy markets.

Geopolitical Drivers

The core driver of the price turbulence remains the US-Iran conflict and the near-complete blockade of the Strait of Hormuz since late February 2026. As Het Laatste Nieuws reports, oil prices surged on June 1-2 following renewed US strikes on Iranian military targets and an Iranian attack on a US airbase. Brent crude rose 3.22 percent to $94.05 per barrel, while US WTI climbed 3.80 percent to $90.68.

The Strait of Hormuz, a narrow waterway between Iran and Oman, handles approximately 20 percent of global oil transit. Its effective closure has sent shockwaves through global energy markets, with Belgium particularly exposed as a net importer of petroleum products.

Historical Context

Diesel reached an all-time record of €2.489 per liter in early April 2026, while petrol 95 last exceeded the €2.00 mark on May 19-20, reaching €2.015 for the first time since July 2022. The current diesel price of €2.08, while below that record, remains painfully high for consumers and businesses alike.

Broader Economic Impact

The fuel price increases are unfolding against a backdrop of broader energy cost pressures. European gas prices have risen approximately 50 percent since the conflict began, hovering around €47 per megawatt-hour. Electricity prices have also spiked, with peaks above €445 per megawatt-hour on May 27 driven by air conditioning demand.

Belgium’s vulnerability to these shocks is amplified by its role as a major energy transit hub. As Flows.be notes, Zeebrugge serves as a critical gateway for LNG imports, and the country hosts significant energy-intensive industry. The VRT NWS has reported on Belgian government deliberations over potential naval involvement in securing the strait, underscoring the strategic stakes for the country.

What This Means for Consumers

For Belgian households, the price increases add to an already challenging cost-of-living environment. The transport sector is feeling the strain as well, with airlines like Transavia implementing fuel surcharges and cost-cutting measures. Across the border, Sweden’s government has halved public transport prices for six months to help citizens cope, though Belgium has not announced equivalent compensatory measures.

Outlook

The trajectory of fuel prices in the coming weeks hinges almost entirely on geopolitical developments in the Middle East. The EU is reportedly considering freezing the price cap on Russian oil to prevent the sanction mechanism from losing effectiveness amid surging global prices. Meanwhile, the UAE is accelerating construction of an alternative oil pipeline to Fujairah, bypassing the Strait of Hormuz entirely, though it is not expected to be operational until 2027.

For now, Belgian consumers face continued uncertainty at the pump, with prices swinging sharply on each new development in US-Iran negotiations or military actions. The fundamental question remains: how long will the Strait of Hormuz remain blocked, and what will it take to restore stability to global oil markets?
