Global oil markets experienced dramatic volatility Thursday as Brent crude reclaimed the $100 per barrel threshold for the first time since August 2022, driven by escalating tensions in the Middle East.

Major U.S. stock indexes tumbled in response to the energy crisis, with the Dow falling 739 points or 1.56%. The S&P 500 dropped 1.52%, while the tech-heavy Nasdaq Composite sank 1.78%, extending a three-day losing streak for major indices.

The market turmoil intensified after an Iranian state television anchor read a statement attributed to Iran's new supreme leader, Mojtaba Khamenei, warning that the crucial Strait of Hormuz will remain closed as a "tool of pressure." The message also declared that all U.S. bases in the region "will be attacked" unless they shut down.

U.S. crude oil prices surged 9.72% to settle at $95.73 per barrel, while Brent crude, the international oil benchmark, rose 9.22% to settle at $100.46 per barrel. The dramatic price movements reflect growing concerns about global energy supply disruptions.

The Strait of Hormuz, a vital waterway off Iran's coast through which 20% of global oil consumption flows, has been effectively closed since the current conflict began. This closure has become the primary driver of oil price volatility and broader market uncertainty.

"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 markets have experienced extreme volatility throughout the week, with Brent crude surging to nearly $120 early Monday before settling at $87.80 Tuesday, only to surge again Wednesday and Thursday to reclaim the psychologically important $100 threshold.

The energy crisis is stoking fears of higher costs and disruptions to the global economy, as investors grapple with the implications of a prolonged closure of one of the world's most critical shipping lanes. The ongoing conflict has created uncertainty about when normal oil flows might resume.

Markets will continue monitoring developments in the region, particularly any signs of diplomatic progress or further escalation that could affect the reopening of the Strait of Hormuz and global energy supplies.
