Lisbon, July 24, 2026 (Lusa) - The price of diesel is expected to rise by nine euro-cents and that of petrol by 3.5 euro-cents per litre next week, should the current trend continue, according to ANAREC's estimate provided to Lusa.
Based on current figures from the Directorate-General for Energy and Geology (DGEG), and taking into account forecasts of price movements based on Thursday's market close, the average price of regular 95 petrol is expected to rise to €2.009 per litre, whilst regular diesel is expected to reach €2.058 per litre.
The final average will be confirmed at the end of the day and may still change depending on developments in international oil prices; the final cost at the pump may vary by petrol station, brand and location. The update to the fuel tax discount is also expected to mitigate the rise.
Meanwhile, the minister for the environment and energy, Maria da Graça Carvalho, has asked the Energy Services Regulatory Authority (ERSE) for a detailed study into the formation and evolution of fuel prices charged at petrol stations.
The request aims to assess whether retail prices have kept pace with changes in international oil, diesel and petrol prices, as well as the speed with which operators pass on price rises and falls.
ERSE, which received the request on 15 July, has 20 working days to submit its analysis. Should the conditions set out by law be met, the minister has also asked the regulator to assess a proposal to set maximum margins in an exceptional setting.
Following an initial rise due to the war in Iran, geopolitical tensions in the Middle East and the closure of the Strait of Hormuz, fuel prices fell during the ceasefire between Washington and Tehran.
However, with the resumption of the conflict, recent weeks have seen a reversal of this trend, and in line with the rise in oil prices, fuel prices have also risen.
The price of a barrel of Brent crude fell by 2.04% at the opening of European stock markets, to $98.71, after reaching $101 in the early hours of the morning.
Its US equivalent, West Texas Intermediate (WTI), fell by 1.80% to $90.53.
Following the thirteenth night of US strikes against Iranian targets, oil prices have eased from the rises seen on Thursday.
Over the course of the week, the price of a barrel of Brent rose by more than $10, at a time when US President Donald Trump was vowing to continue the attacks on Iran, particularly following the Houthis' involvement in the conflict in the region.
