U.S. Blockade of Strait of Hormuz Triggers Oil Spike and European Market Slide

European equity markets retreated on Monday as geopolitical tensions escalated in the Middle East, driven by a U.S. naval blockade of the Strait of Hormuz. The move follows the collapse of weekend peace negotiations between Washington and Tehran, leaving the two nations without a resolution to the ongoing conflict. The blockade, announced by the U.S. President via Truth Social, aims to pressure Iran by restricting the flow of vessels through one of the world's most critical oil transit points. The administration characterized the move as a necessary response to prevent Iran from profiting from what it termed an illegal act of extortion. Energy markets reacted violently to the news. Brent crude futures experienced significant volatility, peaking at $103.87 per barrel—a nearly 9% increase—before settling at $101.50, representing a 6.5% gain. This surge in energy costs reignited growth concerns across the Eurozone. Equity indices across Europe finished the session in the red. The pan-European Stoxx 600 declined by 0.16%, while Germany's DAX and France's CAC 40 fell 0.26% and 0.29%, respectively. The U.K.'s FTSE 100 also closed lower, slipping 0.17%. Sectoral performance was sharply divided. Defense and energy firms saw gains, with Rheinmetall rising nearly 3% and several energy-related entities posting gains between 1% and 3.2%. Conversely, growth-sensitive stocks and telecommunications struggled, highlighted by a more than 6% drop in Deutsche Telekom and losses across various French and British blue-chip companies.
