Iran announces controlled maritime zone for ships transiting Strait of Hormuz

What happened

Middle East Eye reports that Iran’s Persian Gulf Strait Authority has established a controlled maritime zone in the Strait of Hormuz, requiring vessels to obtain authorisation before passage. The authority detailed on X that this zone extends from Kuh-e Mubarak in Iran to south of Fujairah in the UAE on the eastern side, and from the tip of Qeshm Island to Umm al-Quwain at the strait’s western entrance.

This move marks a significant tightening of Iranian control over one of the world’s most critical maritime chokepoints, through which a substantial share of global oil shipments pass. The requirement for ships to coordinate with and gain authorisation from the Iranian authority signals potential new restrictions or checks on international shipping.

The Strait of Hormuz has historically been a flashpoint for regional tensions involving Iran, Gulf states, and international navies. Iran’s formalisation of a controlled zone could impact the dynamics of maritime security, freedom of navigation, and sanctions enforcement regimes around Iran’s shipping routes.
