The military escalation in the Middle East, particularly the conflict in Iran, is exerting immediate pressure on global energy markets, leading to rising electricity prices in the Iberian Peninsula. Experts warn that the duration and severity of the conflict will significantly influence energy prices, with predictions of oil prices potentially reaching $90 to $100 if the situation persists. This escalation poses challenges for public finances in Portugal, as rising fuel and gas prices complicate economic stability.
Conflict in Iran already affects Iberian electricity prices. Industry more vulnerable

Context & Explainers
Higher crude oil prices raise wholesale fuel costs, and those increases typically reach Portuguese petrol and diesel pumps within days to weeks; the recent conflict has pushed oil to one‑year highs and European gas futures up roughly 40%, making fuel the first likely victim. Final pump prices also depend on taxes, VAT and distributor margins, so consumers should expect higher filling‑station bills but the exact change will reflect those tax and margin components as well as exchange rates.
Anarec is the trade association for fuel retailers and convenience stores, formally the National Association of Fuel Retailers and Convenience Stores (Associação Nacional de Revendedores de Combustíveis e de Lojas de Conveniência). Its leaders monitor and comment on retail fuel trends — for example the association’s vice-president Mafalda Trigo said diesel could rise by about €0.10 next week — so drivers and businesses should watch price updates.
