In July 2026, Belgium introduced new maximum prices for diesel, 95-octane gasoline, and heating oil. This period saw significant volatility; by late July, diesel prices rose again due to Brent crude fluctuations, with Belgian diesel B7 reaching €2.253/L. Simultaneously, the government implemented tax increases on natural gas and heating oil effective August 1 to curb fossil-fuel consumption, while ending its energy aid programme.

Inflation in July reached 3.5%, outpacing neighboring EU countries like France, Germany, and the Netherlands. This was largely driven by a 14.3% surge in energy costs. Economists noted that Belgium’s high proportion of variable-rate contracts and specific CPI methodology amplified these headline figures. 

By early August, fuel prices saw a temporary reprieve as Brent crude declined following news of a cancelled planned attack on Iran. This led to a reduction in Belgian maximum prices, creating a significant price gap compared to the Netherlands. However, energy costs in Flanders reached three-year highs in August. For households on variable contracts, annual electricity and gas expenses rose significantly, with gas costs increasing by an estimated €290 per year due to a combination of higher prices and federal taxes.

These developments underscore the ongoing fiscal and environmental challenges facing Belgian households, as wholesale market volatility and tax adjustments continue to impact consumer costs.
