Portugal increases fuel tax discount to 7.4 cents on diesel and 4.6 cents on gasoline
The Portuguese government raised its fuel tax discount on 17 July, citing expectations of higher pump prices and insisting the state should not profit from war or inflation.
Announcement
The Portuguese government reinforced its fuel tax discount on 17 July, setting the reduction at 7.4 cents per litre for diesel and 4.6 cents per litre for gasoline. The decision was announced by the Minister of the Presidency, António Leitão Amaro, after a Council of Ministers meeting in Lisbon.
The Government decided, given the information we have that markets and retailers will raise prices, to increase the discount.
For diesel, the minister said the additional discount before tax was six cents, which with tax becomes 7.4 cents. For gasoline, the 4.6-cent discount translates to 5.7 cents when tax is included.
- Diesel
- 7.4 cents
- Gasoline
- 4.6 cents
Why prices are climbing
The move comes as international fuel markets face renewed pressure from the Middle East conflict. Disruptions in the Strait of Hormuz have affected production, refining activity, maritime transport and product availability, while also raising risk premiums and freight costs.
Portugal does not depend mostly on Gulf oil, but it is exposed to a global market where supply shifts, refining capacity, freight rates and risk perception can quickly feed into prices. Diesel is particularly sensitive because Europe is a net importer and relies on external suppliers to balance consumption.
The regulator's numbers
For the week of 13 to 19 July, the efficient price calculated by the energy regulator ERSE rose 1.5% for gasoline and 3.8% for diesel. Those increases reflected jumps of 4.3% and 9.7% in the international quotations of the two refined products.
The regulator's data underpin the government's expectation that pump prices are set to climb, prompting the tax discount reinforcement.
How fuel prices are formed
Retail fuel prices do not move in lockstep with crude oil. Gasoline and diesel are refined products with their own international markets and distinct price-setting logic. On top of the crude price, costs and margins for refining, maritime freight, storage, logistics, biofuels, retail and taxes all shape the final number at the pump.
The national association of fuel retailers, ANAREC, stresses that the gasoline and diesel arriving at service stations are not crude oil but already refined products, traded on separate international markets.
The government's stance
Leitão Amaro made clear that the state should not benefit from rising fuel costs driven by external shocks.
The State does not profit from war and the State does not profit from inflation, particularly from the one that has been most relevant, which is fuel prices.
The discount is applied through a reduction in the ISP fuel tax. The government framed the measure as a way to return to consumers what would otherwise be extra tax revenue generated by higher prices.
