Regional Government changes fuel maximum price calculation formula

The Regional Government of Madeira, through Ordinance no. 166/2026, published in the Official Journal of the Autonomous Region of Madeira (JORAM), has made a significant change to the calculation formula for the maximum retail prices of unleaded petrol IO 95, road diesel, and colored and marked diesel.

This measure comes as a response to the extraordinary increase in fuel prices, driven by the geopolitical and military crisis in the Middle East, which has created uncertainty in oil markets and direct impacts on Madeiran families and businesses. The central objective is to mitigate the economic effects of this situation through a technical adjustment to the price structure.

Main changes:

• Exclusion of the adjustment factor: The new wording of Article 2 of Ordinance no. 25/2022, of January 26, eliminates the previously provided adjustment factor, simplifying the calculation formula.
• New basic formula: The maximum retail price (PMVP) is now determined by the sum of the weighted average price excluding taxes (PMP), transport and storage costs (CT), tax on petroleum and energy products (ISP), and value-added tax (VAT).
• Revocations: The new ordinance expressly revokes Article 8 of Ordinance no. 25/2022 and Ordinance no. 140/2026, of March 27.

The measure entered into force on the date of its publication, April 10, 2026, and was signed by the Regional Secretary for the Economy, José Manuel de Sousa Rodrigues, and the Regional Secretary for Finance, Duarte Nuno Nunes de Freitas.
