Iran has implemented a new system for regulating maritime traffic through the Strait of Hormuz, a vital passage for global oil shipments. Under this new mechanism, known as the Persian Gulf Strait Authority (PGSA), vessels intending to navigate the strait must receive prior authorization and adhere to specific transit rules communicated through official channels.

Shipping companies will receive electronic instructions detailing updated guidelines and requirements to follow before crossing the waterway. This initiative is framed by Iranian officials as a form of "sovereign governance" over the strait, reinforcing Tehran's claim to exercise control over a route that facilitates approximately 20% of the world's traded oil.

Amid rising tensions and enhanced military activity in the region, Iranian authorities have warned that any foreign vessels attempting to navigate the strait must coordinate with their military forces. The announcement is also accompanied by a new map of the strait, which expands Iran's claimed area of control.

Iranian parliament speaker Mohammad Bagher Ghalibaf stated that a "new equation" governing the waterway is being established, signaling changes in the operational parameters that could affect international shipping. The naval forces of the Islamic Revolutionary Guard Corps (IRGC) have also issued strict warnings, emphasizing designated maritime corridors that vessels must follow to ensure safe passage.

The geopolitical implications of this development could escalate as the ongoing U.S.-Iran tensions continue to affect the stability of the region. With military and naval operations gaining traction, international shipping companies and governments are closely monitoring the evolving situation to assess the impact on global energy supply and security.

Overall, these new rules represent Iran's response to the strategic challenges posed by foreign military presence in the Strait of Hormuz and underline its intent to reinforce its authority over this crucial maritime route.
