Oil prices declined sharply on Monday, with U.S. crude futures falling by more than 5% as traders reacted to a new U.S. initiative calling for international cooperation to ensure the security of the Strait of Hormuz. The strategic waterway, a critical chokepoint for global oil shipments, has become a focal point amid escalating tensions involving Iran and regional security dynamics. The U.S. announcement signaled a potential shift toward multilateral military or diplomatic involvement to safeguard maritime traffic through the strait, raising concerns about possible disruptions to oil flows. This development has amplified market sensitivity, with the VIX index reflecting increased investor anxiety. Energy stocks, including ExxonMobil (XOM), were also affected, as the rally in risk aversion pressured equities linked to commodity volatility. The broader energy sector now faces heightened scrutiny over supply chain resilience in the face of geopolitical uncertainty.
