U.S.-Iran tensions are sending shockwaves through global markets, forcing business leaders to brace for potential disruptions. The conflict has already led to significant financial volatility, with Brent crude prices surging by 10% following the escalation in hostilities. Experts warn that a closure of the Strait of Hormuz, which handles one-fifth of the world’s oil supply, could push prices as high as $100 per barrel.
