Iran’s parliament has voted in favour of closing the strategic Strait of Hormuz, Iranian media reported on Sunday. The non-binding measure awaits formal approval from the Supreme National Security Council before it can be implemented.
The Strait of Hormuz is one of the world’s most critical maritime passages, with approximately 20% of global oil and gas supply transiting through its narrow waters. Any disruption could have far-reaching implications for international energy markets and shipping routes.
Although the closure is not yet confirmed, senior lawmaker and Islamic Revolutionary Guards Corps commander Esmail Kosari told state media that the plan “is on the agenda and will be implemented whenever necessary.” No timeline was provided for when, or under what specific circumstances, the council might greenlight the shutdown.
At this stage, Tehran’s decision marks a strong political signal rather than an immediate operational change. The Supreme National Security Council must review the parliamentary vote, consider input from Iran’s executive branch, and weigh potential international repercussions before issuing a binding order.
Observers say the move underscores rising tensions in the Gulf region and reflects Tehran’s willingness to leverage its geographic advantage should diplomatic or economic pressures on Iran intensify. However, until formal approval is granted, shipping in the Strait of Hormuz continues without alteration.
