On Sunday, the Iranian parliament voted to close the Strait of Hormuz, a critical maritime chokepoint through which about 20% of the world’s oil and gas supply passes.

The final decision rests with Iran’s Supreme National Security Council. This move comes after U.S. airstrikes hit three major Iranian nuclear sites—Natanz, Esfahan, and Fordow—prompting heightened tensions. Revolutionary Guards Commander Esmail Kosari warned that closing the strait remains under serious consideration and will be executed if necessary. The Strait of Hormuz, just 21 miles wide at its narrowest point, links the Persian Gulf to major global markets. Asian nations such as China, South Korea, and Japan depend heavily on this route, and any disruption could cause a spike in global energy prices.

Despite the threat, Maersk, a major Danish shipping company, stated that its vessels will continue to navigate the strait while monitoring risks closely and adjusting operations if needed. The current tensions escalated following U.S. strikes carried out with Tomahawk missiles and B-2 bombers, responding to prior Israeli military actions. While these strikes have significantly damaged Iran’s nuclear infrastructure, U.S. Defense Secretary Pete Hegseth clarified in a press conference that America does not intend to launch a ground war. The situation remains fluid and under international scrutiny as both military and economic consequences loom.
