Diesel Jumps 16 Cents as Portugal Braces for Another Week of Rising Fuel Prices

Portuguese drivers face yet another sharp increase at the pump next week, with diesel prices expected to climb by 16 cents per litre and petrol by 9 cents, according to data from the Directorate-General for Energy and Geology (DGEG) cited by the Automovel Club Portugal (ACP). If confirmed, regular diesel will hit 2.087 euros per litre and petrol will reach 1.947 euros, continuing a punishing upward trend that has squeezed household budgets and commercial operators across the country.

A Relentless Climb

This is not an isolated spike. Fuel prices in Portugal have been rising steadily for weeks, driven by a combination of global factors that show no signs of easing. The ongoing conflict between the United States and Iran has disrupted oil supply chains and pushed crude prices higher on international markets. The European benchmark, Brent crude, has traded well above 90 dollars per barrel through March, and analysts expect continued volatility as the geopolitical situation evolves.

For Portugal, which imports virtually all of its petroleum products, there is limited domestic cushion against these global pressures. The country's fuel tax structure, which includes ISP (Imposto sobre os Produtos Petroliferos) and VAT at 23 percent, means that every cent of increase in the base commodity price is amplified at the pump.

Government Response

The Government approved an emergency fuel price reduction package on 13 March, including a temporary cut to the ISP on diesel. However, the International Energy Agency and several domestic analysts have warned that such measures risk creating fiscal problems without addressing the structural dependence on imported fossil fuels.

The ACP has been vocal in its criticism, calling for more substantial intervention. In a statement released on 21 March, the automobile club said the country "needs leadership" on the fuel crisis and urged the Government to go further in protecting consumers and commercial transport operators.

For its part, the Government has pointed to the recently approved Emergency Energy Price Cap legislation as evidence of its commitment to shielding households from the worst impacts. That law, which passed the Assembleia da Republica this week, gives the Council of Ministers authority to cap energy prices in exceptional circumstances, though the specific mechanisms and triggers remain to be defined through regulation.

Impact on Daily Life

The practical consequences of diesel approaching 2.10 euros per litre are felt across the economy, not just by motorists. Portugal's logistics sector relies heavily on road transport, and fuel costs feed directly into the price of food, building materials, and consumer goods. The CAP (Confederation of Portuguese Farmers) warned on 21 March that the country should be "prepared for a brutal direct impact" on food prices.

For commuters, particularly those in rural and suburban areas where public transport options are limited, the cost of getting to work continues to rise. A typical 60-litre diesel fill now costs roughly 125 euros, up from around 95 euros this time last year.

What Residents Can Do

The IEA's 10-point plan for reducing oil dependence includes recommendations applicable to individual consumers: carpooling, reducing speed on motorways, and shifting short trips to public transport or cycling where possible. Portugal's growing network of electric vehicle charging points offers a longer-term alternative, though the upfront cost of EVs remains prohibitive for many households.

For those who must drive, price comparison apps such as Mais Gasolina allow users to identify the cheapest stations in their area. Prices can vary by several cents per litre between competing stations, and the savings add up over time. Filling up before Monday's price increase takes effect is the most immediate action available.
