Iran War and Strait of Hormuz Closure: Global Energy Crisis Deepens

The ongoing conflict between Iran, the United States, and Israel has effectively closed the Strait of Hormuz, a critical waterway for global oil and natural gas transport, triggering a significant energy supply shock. This closure, coupled with attacks on energy infrastructure in the Middle East, is sending ripples through international markets and impacting economies worldwide.

Strait of Hormuz: A Vital Chokepoint

The Strait of Hormuz, located between Iran and Oman, is a narrow but strategically important passage. At its narrowest point, it is 21 miles wide [2]. Approximately 20% of the world’s crude oil and natural gas typically passes through this strait [1]. Its closure represents a major disruption to global energy supplies.

Escalation of the Crisis

The crisis began on February 28, 2026, following joint military strikes by the U.S. And Israel on Iran, including the killing of Iran’s supreme leader, Ali Khamenei [2]. Iran responded by declaring the Strait of Hormuz closed and attacking ships attempting to navigate the route. Recent attacks have also targeted oil and gas infrastructure in Saudi Arabia, Qatar, and the UAE, raising concerns about alternative routes for oil transport [1].

Impact on Global Markets

The closure of the Strait of Hormuz has had an immediate and substantial impact on global energy markets. Global crude oil prices have risen more than 10% since the U.S. And Israel’s attacks on Iran [1]. Natural gas prices in Europe and Asia, which heavily rely on imported liquefied natural gas (LNG), have also increased sharply. Approximately 20 million barrels of oil per day typically transit the strait [1].

Limited Mitigation Efforts

While some countries, including the U.S., maintain oil stockpiles, and certain Gulf region producers can redirect oil to other ports, these measures are insufficient to fully offset the supply shortfall [1]. Damage to infrastructure in neighboring countries further complicates the situation, potentially prolonging the disruption even after the strait reopens.

Political Responses

U.S. President Donald Trump has stated that the rise in oil prices is a “very small price to pay” for “safety and peace” [1]. However, investors have warned of the potential for stagflation if the conflict continues [1]. Iran’s ambassador to China has denounced the U.S. And Israel as sources of insecurity in the Strait of Hormuz and called for their withdrawal from the area [3].

Casualties

As of March 10, 2026, the crisis has resulted in the deaths of eight seafarers and at least four tankers have been damaged [2]. One port worker has been killed and two injured in Bahrain [2].
