Context & Explainers
Inflation measures how much general prices rise over time, usually reported year‑on‑year to compare a month with the same month a year earlier. Portugal’s National Institute of Statistics (INE) estimated January inflation at 1.9% year‑on‑year, down 0.3 percentage points from December, which affects rents, wages and everyday purchasing power for residents.
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.
