Major US stock indexes extended their losing streak Thursday as escalating tensions in the Middle East sent oil prices soaring back above the $100 per barrel mark for the first time since 2022.
The Dow Jones Industrial Average plummeted 739 points, or 1.56%, while the S&P 500 dropped 1.52% and the tech-heavy Nasdaq Composite sank 1.78%. The three-day decline reflects growing investor anxiety over the ongoing conflict's impact on global energy supplies and economic stability.
Oil markets experienced dramatic volatility as Brent crude, the international benchmark, surged 9.22% to settle at $100.46 per barrel. US crude prices jumped 9.72% to close at $95.73 per barrel, marking Brent's first settlement above $100 since August 2022.
The energy surge came after an Iranian state television anchor delivered a stark warning attributed to Iran's new supreme leader, Mojtaba Khamenei. The statement declared that the crucial Strait of Hormuz will remain closed as a "tool of pressure" and threatened that all US bases in the region "will be attacked" unless they shut down.
The Strait of Hormuz, a vital waterway off Iran's coast, serves as a critical chokepoint for global energy supplies, with approximately 20% of worldwide oil consumption flowing through the passage. The effective closure of this strategic waterway since the current conflict began has created significant disruptions to international oil markets.
"The implicit closure of the Strait of Hormuz remains the hinge factor for global markets," said Felix Vezina-Poirier, chief strategist at BCA Research.
Oil prices have experienced extreme volatility throughout the week, reflecting the uncertainty surrounding the Middle East crisis. Brent crude initially surged to nearly $120 early Monday before settling at $87.80 on Tuesday, only to climb sharply again Wednesday and Thursday to reclaim the psychologically important $100 threshold.
The energy sector's turbulence has created broader market instability, with investors grappling with the potential for sustained higher energy costs and their impact on global economic growth. The combination of supply disruptions and geopolitical tensions has reignited concerns about inflation and economic stability that had begun to subside in recent months.
Market participants are closely monitoring developments in the region, particularly any changes in the status of the Strait of Hormuz and the potential for diplomatic resolution. The continued closure of this critical shipping lane poses significant risks to global energy security and economic stability.
Investors will be watching for any signals of de-escalation in the conflict or potential coordination among international energy agencies to address supply disruptions. The market's reaction to Iran's latest threats suggests that geopolitical tensions will likely remain a dominant factor in both energy and equity markets in the near term.
