Iran Imposes New Maritime Rules in Strait of Hormuz, Tightens Control Over Key Shipping Route

Iran has announced a new set of maritime regulations governing traffic through the strategic Strait of Hormuz, requiring all vessels to obtain authorization from its naval forces before entering the passage.

In a statement, the naval branch of the Islamic Revolutionary Guard Corps (IRGC) said a “new order” is now in effect, under which all commercial ships must follow designated routes approved by Iranian authorities. It also stated that no military vessels will be allowed to transit through the waterway, which Tehran considers firmly under its control.

According to the IRGC Navy, all maritime movement—commercial or otherwise—will only be permitted with explicit approval from its command. The announcement underscores Iran’s tightened regulatory grip over one of the world’s most critical energy corridors, through which roughly one-fifth of global oil shipments pass.

The IRGC said the measures are being implemented in line with a ceasefire framework linked to recent regional developments, including a ceasefire in Lebanon and broader understandings involving Iran and the United States.

Iranian Foreign Minister Abbas Araghchi earlier stated that commercial navigation through the Strait of Hormuz had been reopened under coordinated arrangements with Iranian maritime authorities. Foreign ministry spokesperson Esmaeil Baghaei later clarified that all vessel movement must still follow routes designated by Iran and remain under official coordination.

The Strait of Hormuz, located between the Persian Gulf and the Gulf of Oman, is widely regarded as one of the most sensitive chokepoints in global energy trade. Any disruption or restriction in the area can have immediate impacts on international oil and gas markets.

Iranian officials argue that their control measures are necessary for security and coordination, especially following recent military tensions involving the United States and its allies. Tehran has previously warned that it would restrict access to hostile naval forces while allowing regulated commercial passage.

The IRGC Navy reiterated that foreign military presence in the region remains unacceptable, while insisting that Iran continues to safeguard navigation for approved commercial shipping under its new framework.
