From September 7, 2026, fuel prices in Portugal are expected to undergo significant changes, with increases in both petrol and diesel. According to industry sources, petrol is expected to rise by about 12 cents per liter and diesel by about 15 cents per liter. On Friday, September 4, the average price of diesel was 2.019 euros per liter and petrol was 2.022 euros per liter.
If the forecasts are confirmed, the average price of diesel will rise to 2.169 euros per liter, while petrol will reach 2.142 euros per liter. However, some fuel stations may show less significant price variations, as the sector is liberalized and each station sets its own pricing policy.
The price increase is directly related to the current war context in the Middle East. The United States, Israel and Iran are involved in military attacks in the region, which caused the blockade of the Strait of Hormuz, through which approximately 20% of world oil and natural gas trade passes.
This conflict is causing strong fluctuations in fuel prices throughout Europe, naturally also affecting Portugal. The situation in the Middle East continues to be the main cause of variations in global energy markets.
