Diesel jumps 19 cents; queues form at pumps
Diesel prices in Portugal are set to rise by about €0.19 and petrol by roughly €0.07 next Monday, prompting long queues at filling stations as motorists top up in advance. Consumer group DECO PROteste warned higher fuel costs will ripple through the economy, increasing transport and food prices, while analysts flag fertilizer supply pressures tied to Brent crude and tensions around the Strait of Hormuz. The price shock has also prompted political pushback, with some parties demanding an urgent parliamentary debate on relief measures. Drivers and shoppers should expect higher local transport and grocery costs in the coming weeks.
Update: Chega leader calls for VAT return, urgent debate
André Ventura, leader of Chega, challenged the government to “return to taxpayers” the extra VAT (IVA (Imposto sobre o Valor Acrescentado)) revenue generated by the coming fuel-price rise and said his party will ask for an urgent debate in the Assembleia da República next week; he also described the government’s 3.55‑cent ISP (Imposto sobre Produtos Petrolíferos or ISP) discount as insufficient.
Deco Proteste is Portugal's largest consumer rights organization, providing independent product testing, legal advice, dispute mediation, and advocacy on behalf of consumers. It is part of the international Euroconsumers group.
Deco publishes comparative tests of products and services (from insurance policies to supermarket prices), lobbies for consumer-friendly legislation, and runs a mediation service that helps resolve disputes between consumers and companies. It also operates helplines during crises — such as severe weather events — to advise on insurance claims, billing disputes, and emergency consumer rights.
Membership is paid, but Deco's public advocacy and media presence make it a significant voice in Portuguese consumer affairs. Its studies and reports are frequently cited in news coverage of cost-of-living, energy prices, and financial products.
Brent crude is a major international oil price benchmark made up of several light, low-sulfur crude oils produced in the North Sea; its price is quoted in US dollars per barrel. It is one of the two main global benchmarks, alongside West Texas Intermediate (WTI), and is widely used to price shipments to Europe and Africa. Because petrol and diesel in Portugal generally track Brent, a rise in the Brent price usually leads to higher pump prices, higher transport costs, and more expensive goods; one barrel equals 159 litres.
André Ventura, born January 15, 1983, is a lawyer, academic, and Portugal's most prominent far-right leader. He founded Chega ("Enough") in 2019 after his PSD mayoral campaign attacked the Romani community. Chega surged from 1.3% in 2019 to 22.8% in May 2025, becoming parliament's second-largest party and making Ventura Leader of the Opposition.
His platform emphasizes immigration restrictions, law-and-order policies, constitutional reform, and contains inflammatory anti-Romani rhetoric that has triggered multiple discrimination convictions and investigations. Politically classified as far-right by international media, Ventura cultivates alliances with European far-right figures including Marine Le Pen and Santiago Abascal.
The ISP (Imposto sobre Produtos Petrolíferos e Energéticos) is Portugal's excise tax on petroleum and energy products, charged as a fixed amount per liter on petrol, diesel, and other fuels. It is one of the main components of fuel prices at the pump, alongside VAT and the carbon tax (Taxa de Carbono).
The government can adjust ISP rates — temporarily or permanently — to influence fuel prices. Rate cuts are a common policy tool to ease cost-of-living pressures on drivers and transport businesses, though they also reduce government revenue.
For consumers, the ISP is significant because even small changes in the per-liter rate translate into noticeable differences at the pump, particularly for diesel users and commercial transport operators.
