Global Markets Plunge as Strait of Hormuz Closure Fears Mount

LONDON (AP) — Global stock markets tumbled on Monday as renewed tensions over the war in Iran and fears of a prolonged closure of the Strait of Hormuz sent investors scrambling for safety. Major indices across the United States, Europe, and Asia posted significant losses following the U.S. seizure of an Iranian vessel, which sparked immediate concerns over critical energy supply lines.

The FTSE 100 in London fell 2.4 percent, while the Euro Stoxx 50 dropped 3.1 percent. In the United States, the Dow Jones Industrial Average slid 1,200 points, the S&P 500 lost 3.5 percent, and the Nasdaq Composite fell 4.2 percent. European markets mirrored the decline, with Germany’s DAX down 3.8 percent, France’s CAC 40 slipping 3.2 percent, and Spain’s IBEX 35 dropping 2.9 percent.

The sell-off was driven by escalating uncertainty regarding the Strait of Hormuz, a vital waterway through which approximately 20 percent of the world’s oil passes. The closure of the strait, confirmed by maritime authorities following the seizure of the Iranian ship by U.S. naval forces, has raised alarms about potential disruptions to global energy supplies. Oil prices surged in response, with Brent crude climbing above $115 per barrel and West Texas Intermediate reaching $108.

Tensions between the United States and Iran have intensified in recent weeks, with both nations exchanging diplomatic accusations and military posturing. The seizure of the vessel, which U.S. officials described as carrying illicit cargo, was met with strong condemnation from Tehran. Iranian state media warned of "severe consequences" if the ship was not immediately released, while U.S. officials maintained that the action was a lawful enforcement of international sanctions.

Analysts noted that the market reaction reflected deep-seated fears of a broader regional conflict. "The closure of the Strait of Hormuz is a red line for global markets," said one senior strategist. "Any disruption here could trigger a supply shock that ripples through every sector of the economy." The volatility has also impacted currency markets, with the U.S. dollar strengthening against major peers as investors sought safe-haven assets.

Despite the sharp declines, some sectors showed resilience. Energy stocks initially surged on higher oil prices, though gains were short-lived as broader market sentiment turned negative. Technology and consumer discretionary stocks were hit hardest, with investors reducing exposure to high-risk assets amid the geopolitical uncertainty.

The situation remains fluid, with no clear resolution in sight. Diplomatic channels are reportedly active, but neither side has indicated a willingness to de-escalate. The status of the seized vessel and the future of the Strait of Hormuz remain unresolved, leaving markets on edge as investors await further developments. Traders are closely monitoring any signs of military escalation or diplomatic breakthroughs that could stabilize the region and restore confidence in global supply chains.
