An Iranian member of parliament has called for the closure of the Strait of Hormuz, a move that could escalate geopolitical tensions and disrupt global oil markets. The lawmaker cited recent actions by the United States and Israel as the reason for the demand, though no specific incidents were named.
The call from Tehran
The MP, whose name was not disclosed in the initial reports, urged the Iranian government to shut the strategic waterway in response to what he described as hostile steps by Washington and Tel Aviv. The Strait of Hormuz is a narrow passage between Iran and Oman, through which roughly one-fifth of the world's oil supply passes daily. Any attempt to block it would be a dramatic escalation in the region's already volatile security landscape.
Iran has threatened to close the strait in the past during periods of heightened tension, but has never followed through. The latest call comes amid a broader standoff over Iran's nuclear program and its support for proxy forces across the Middle East.
Global oil market risks
Oil prices are highly sensitive to any disruption in the Strait of Hormuz. A closure could send crude prices soaring, as tankers would be forced to take longer, costlier routes around Africa. Analysts have long warned that even a temporary blockage could trigger a supply shock, particularly for Asian economies that rely heavily on Gulf oil.
The lawmaker's statement alone is unlikely to move markets immediately, but it adds to the uncertainty that has kept traders on edge. The U.S. and its allies maintain a naval presence in the region to ensure freedom of navigation, and any Iranian attempt to close the strait would likely provoke a military response.
Shipping and security concerns
Beyond oil, the strait is a critical chokepoint for liquefied natural gas and other goods. Insurance premiums for vessels transiting the area would spike, and shipping companies might reroute cargoes, driving up costs for consumers worldwide. The U.S. Navy's Fifth Fleet, based in Bahrain, is tasked with keeping the waterway open.
Iran's government has not officially responded to the MP's call. The country's supreme leader, Ayatollah Ali Khamenei, holds ultimate authority over security decisions, and it remains unclear whether the parliament's hardline faction can push for such a drastic step.
What happens next depends on how the U.S. and Israel respond to the rhetoric — and whether Tehran decides to turn words into action.
