US-Israel War with Iran: Economic Fallout and European Concerns
The recent US-Israeli military campaign against Iran, initiated on February 28, 2026, has triggered a wave of repercussions extending far beyond the Middle East. The conflict, which resulted in the deaths of Iran’s Supreme Leader Ayatollah Ali Khamenei and numerous senior Iranian officials1, is creating a cascade of political and economic problems for Europe, including soaring energy prices, potential security threats, and the risk of wider instability.
Economic Repercussions: Energy Markets in Crisis
A primary concern for Europe is the disruption to global energy markets. The newly appointed Supreme Leader, Mojtaba Khamenei, has declared the Strait of Hormuz – a critical waterway for global oil transit, handling approximately 20% of the world’s oil supply – will remain closed to shipping.2 Recent incidents, including strikes on five oil vessels in the region, underscore this threat.1
Oxford Economics has warned of a worst-case scenario where Brent crude averages $140 per barrel for several months, significantly impacting real disposable income and consumer spending.2 The surge in oil prices is expected to elevate transportation costs and drive up the prices of food and other essential goods, potentially leading to sustained inflationary pressures.
European leaders, already grappling with high energy prices stemming from Russia’s invasion of Ukraine – with retail electricity prices currently 36% above the 2014-2020 average – are facing a renewed crisis.2
European Responses and Concerns
EU leaders, gathering for a summit, are seeking solutions to mitigate the economic fallout. Italian Prime Minister Giorgia Meloni has cautioned against price speculation, and France has conducted 500 checks at fuel stations to prevent exploitation.2
The situation evokes memories of the 2022 energy crisis triggered by Russia’s invasion of Ukraine, which forced Europe to abandon reliance on cheap Russian oil and gas. While the EU has reduced its dependence on Russian gas from 45% to 12%, replacing it with US Liquefied Natural Gas (LNG), Norway, and Qatar, the current crisis centers on price rather than supply.2
Gas prices in Europe have risen by 75% compared to the start of the year, with significant volatility observed in markets like Denmark, where prices fluctuated wildly on March 4, 2026.2
Potential Solutions and Challenges
The European Commission is preparing proposals for EU leaders, examining the components of electricity production costs – generation (56%), grid charges (18%), taxes and levies (15%), and carbon emissions (11%).2 Significant variations exist among member states in pricing, taxation, and grid management, impacting the competitiveness of the EU’s single market.
Disparities in electricity prices are stark, ranging from as low as €16.10 per megawatt hour in parts of Sweden and Norway to over €115 in Ireland. Countries reliant on gas face higher prices.2
Ongoing infrastructure projects, such as the Celtic Interconnector between Ireland and France (due in 2028), and increased offshore wind energy, offer potential relief. However, challenges remain, including local opposition to grid infrastructure projects, as seen in Germany.2
EU Energy Commissioner Dan Jørgensen has urged governments to lower taxes and levies on electricity, potentially saving European households an average of €200 per year.2 Discussions are also underway regarding a potential price cap on gas and changes to the Emissions Trading System (ETS).
Geopolitical Considerations
The conflict raises concerns about Europe’s energy security and its reliance on external suppliers. While increased US LNG exports have provided some relief, questions arise about whether Europe is simply shifting its dependence from Russia to the United States.2
The situation remains fluid, and the duration of the conflict is uncertain. Iran’s ability to disrupt energy exports through attacks on infrastructure gives it significant leverage.2
