Strait of Hormuz Crisis Sends Fuel Prices Surging Across Portugal

The ripple effects of the Strait of Hormuz disruption have reached Portuguese petrol stations with punishing force. Diesel and gasoline are set to climb another 10 cents per liter starting Monday, pushing diesel toward 1.92 euros per liter and gasoline to roughly 1.85 euros — the steepest prices the country has seen in years.

The crisis, now entering its third week, stems from the disruption of maritime traffic through the narrow waterway between Iran and Oman, through which roughly 20 percent of the world's oil and a quarter of its liquefied natural gas normally flows. Brent crude has surpassed $100 per barrel, and Portugal — despite importing only modest volumes directly from the Persian Gulf — remains acutely exposed to the volatility of European spot markets.

Government Subsidies: The First Line of Defense

The Montenegro government has responded with expanded fuel subsidy programs, including a 3.55-cent ISP discount on diesel designed to prevent the state from profiting on windfall tax revenues during the spike. Economy Minister Manuel Castro Almeida has framed this as a responsible, market-stabilizing approach. "The government will not take fiscal advantages from regional instability," he told reporters in Porto. "What would be additional tax revenue is returned through ISP to lower the price of gasoline and diesel."

Subsidies are being applied automatically at qualifying petrol stations, with no separate application required for regular consumers. Transport operators and commercial vehicles receive enhanced rebates, and support has been extended to public transportation and emergency services. The government has committed to maintaining these measures through at least mid-April, with quarterly reviews tied to crude oil prices and budget capacity.

Opposition Pushes for Price Controls

The left-wing opposition is not satisfied. Bloco de Esquerda coordinator José Manuel Pureza announced legislation for tabelamento — state-mandated price ceilings on essential goods, fuel, and energy. The Partido Comunista Português has drafted a parallel bill establishing a maximum price regime for select food products. Consumer advocacy groups report that Portugal's essential goods basket has hit all-time highs this month.

The proposals face stiff resistance from economists and market-oriented policymakers who warn that rigid price caps during supply shocks typically create unintended consequences — supply disruptions, reduced investment, and even black markets. The government argues that permanent controls could undermine investment in renewable energy infrastructure and grid modernization, both critical to Portugal's long-term energy security and EU climate commitments.

A Broader Vulnerability

Natural gas prices on the Iberian Peninsula have climbed in tandem with global LNG benchmarks, as Qatar — Europe's leading LNG supplier — relies on Hormuz for the majority of its export routes. For anyone who arrived in Portugal expecting relatively affordable living costs, the energy shock is a sharp reminder that the country's economy remains deeply integrated into European and global commodity markets. Electricity bills are projected to rise 10 to 15 percent, and food prices are expected to follow fuel upward through April.

Diplomatic efforts by Qatar, Turkey, and Oman have opened tentative peace channels, and Western allies remain committed to restoring secure maritime passage. But for now, the most practical advice for residents is straightforward: expect higher costs at the pump and in the supermarket through at least mid-spring, and check the Ministry of Economy website or your local municipal council for the latest on subsidy eligibility.
