Decrease in diesel costs anticipated
Portugal Fuel Prices Set to Change Next Week
As of early August 2025, the average price for a litre of diesel in Portugal stands at around €1.59, and it is expected to fall slightly to about €1.585 per litre next week due to government fiscal measures and market dynamics. In contrast, petrol prices, currently averaging €1.678 per litre, are predicted to rise marginally to approximately €1.703 per litre in the coming week [1][2].
These adjustments are a direct result of the Portuguese Government's ongoing fiscal reduction measures, aimed at alleviating fuel costs, particularly focusing on easing diesel prices. The Automóvel Clube de Portugal (ACP) predicts a potential decrease of 1 cent in the price of diesel, while a slight increase of around 2.5 cents per litre is anticipated for petrol [1][2].
The price modulation is influenced by international oil price trends and exchange rates, as well as Portugal’s tax policies on fuels. Despite these changes, petrol prices in Portugal remain slightly above the EU average, with countries like Denmark at €1.98 per litre and Bulgaria at €1.23 [4].
The ACP's predictions for fuel price changes are contingent on the continuation of the Government's fiscal reduction measures. The Direcção Geral de Energia e Geologia (DGEG), Portugal's Directorate-General for Energy and Geology, has provided figures representing the average prices for petrol and diesel as of their most recent statement [2].
It is important to note that no specific long-term predictions beyond the immediate next week have been provided in the available sources. However, the recent trend shows diesel prices easing as part of government intervention, while petrol prices face a small upward adjustment [1][2].
The Government's fiscal reduction measures are a factor in the predicted decrease in diesel prices, and the purpose of these measures is to reduce the prices of fuel for consumers. The DGEG and the ACP are the Portuguese authorities responsible for providing information on fuel prices and market trends.

The Portuguese Government's continuing fiscal reduction measures are expected to decrease diesel prices slightly, while petrol prices might increase marginally, as predicted by the Automóvel Clube de Portugal. These changes in fuel prices are connected to the industry, finance, and transportation sectors in Portugal.
These adjustments in diesel and petrol prices are influenced by factors such as international oil price trends, exchange rates, and Portugal’s tax policies on fuels, which are areas closely tied to the finance and industry sectors. The Directorate-General for Energy and Geology (DGEG) and the Automóvel Clube de Portugal (ACP), two Portuguese authorities, provide information about fuel prices and market trends, linking directly to the transportation sector.
