September has arrived with little change in fuel prices: simple gasoline 95 remained at the previous week’s level, while diesel saw a slight adjustment.
According to updated data from the Directorate-General for Energy and Geology, the average price of simple gasoline 95 stands at 1.698 euros per liter, the same as on Friday, indicating no change in price.
The simple diesel price increased slightly from 1.545 euros per liter to 1.548 euros per liter during the same period, a rise of less than half a cent.
The Automobile Club of Portugal (ACP) indicated on Friday that diesel was expected to become 0.5 cents more expensive, while gasoline could be 0.5 cents cheaper.
“Next week will see changes in fuel prices, with forecasts suggesting an increase of half a cent in diesel prices, while gasoline is expected to drop by half a cent,” stated the ACP.
“Should the forecasts for next week be confirmed, the average price of simple diesel should rise to 1.550 euros per liter, while the average price of simple gasoline 95 should drop to 1.693 euros per liter,” noted the ACP.

The week begins with varied shifts in fuel prices. Predictions released by the Automobile Club of Portugal (ACP) on Friday suggest that diesel will increase by 0.5 cents and gasoline will decrease by 0.5 cents.

What about oil prices?
The Brent crude price for November delivery ended Monday on the London futures market with a slight increase of 0.04%, reaching 68.15 dollars.
The North Sea crude, a European benchmark, concluded the session on the Intercontinental Exchange, trading three cents higher than the closing price of 68.12 dollars on Friday.
Brent opened September without much fluctuation as investors remain cautious about potential oil supply disruptions from Russia following recent Ukrainian attacks on Russian refineries and the possible imposition of further sanctions by the US and European states.
“If the US eases sanctions or intensifies pressure on China and India, global trade may be affected, reducing market risk,” estimated Forex analyst Razan Hilal.
Investors are also focusing on the upcoming meeting of the Organization of the Petroleum Exporting Countries (OPEC) and its allies, including Russia, collectively known as OPEC+, scheduled for Sunday. During this meeting, they are expected to decide whether to continue increasing production amid concerns of a potential oversupply.

The decision depends on the type of fuel, as diesel becomes more expensive and gasoline cheaper.
