The Minister of Finance has assured that the government is working on a solution to end the discounts on the fuel tax (ISP), as recommended by the European Commission, without increasing fuel prices.
“We will look for moments of price reduction to be able to reverse these discounts,” stated the Minister of State and Finance, Joaquim Miranda Sarmento, while presenting the State Budget proposal for 2026 in Lisbon.
The minister noted that this issue has been raised by the European Commission since 2023, as it was the “only remark” made by the institution during the assessment of the Medium-Term Budgetary Program in October of last year, and in a new letter received in June, urging the government to end the ISP discounts.
The Minister of Economy and Territorial Cohesion, Manuel Castro Almeida, had already admitted possible “adjustments” in fuel prices.

Brent, which surpassed 70 dollars per barrel at the end of September, experienced a decline of nearly ten dollars in less than a month after the geopolitical risk premium diminished following developments in Gaza and Ukraine.
