The beginning of this week was marked by an increase in fuel prices, affecting both diesel and gasoline, as indicated by the average prices provided by the Directorate-General for Energy and Geology (DGEG).
Simple 95 gasoline rose from 1.700 euros per liter to 1.716 euros per liter between Friday and Sunday, reflecting an increase of 1.6 cents.
Meanwhile, simple diesel increased from 1.555 euros per liter to 1.568 euros per liter over the same period, rising by 1.3 cents.
These average daily prices, it should be noted, are calculated based on the prices reported by fuel stations, weighted with the quantities sold during the last known period, incorporating the discounts offered at service stations such as fleet cards and others.
The predictions indicated a rise in prices was expected this week. The Automobile Club of Portugal (ACP) announced on Friday that both diesel and gasoline were set to increase by half a cent.
“After a week without changes, fuel prices are set to change again, with forecasts pointing towards an increase in the price of diesel and gasoline,” stated the ACP.
These forecasts were released at a time when, according to the Directorate-General for Energy and Geology (DGEG), the average price of a liter of diesel in Portugal was 1.555 euros on Friday (September 19), while gasoline was priced at 1.699 euros.
The ACP emphasized that “these forecasts are based on the assumption of maintaining the extraordinary tax reduction measures applied by the government to mitigate the price increase.”

How is oil doing in international markets?
The price of a Brent barrel for November delivery closed today on the London futures market, down by 0.16%, to 66.57 dollars.
The North Sea crude, the reference in Europe, ended the session at the Intercontinental Exchange, 11 cents below the 66.68 dollars at which it closed transactions on Friday.
Brent starts the week on a downward trend, affected by concerns about oversupply following policies to increase production by the Organization of Petroleum Exporting Countries (OPEC) and allies, collectively known as OPEC+, amid insufficient demand.
As noted today by analyst Fawad Razaqzada of Stonex in his weekly bulletin, oil has been “struggling to find significant impetus” in recent weeks, despite the geopolitical context – Russia and the Middle East – because OPEC+’s policy has left the market “vulnerable” to new declines.

Attention, drivers: fuel prices will increase starting Monday.
