The system aims to manage transit through the 39-kilometer-wide waterway by routing inbound vessels through northern Iranian territorial waters and outbound traffic through southern Omani waters.
Strait of Hormuz Shipping Lanes and Territorial Overlap
At its narrowest point, the Strait of Hormuz spans approximately 39 kilometers. Both Iran and Oman claim a 12-nautical-mile zone, which equals roughly 22.2 kilometers, causing the territorial waters of the two coastal states to overlap entirely. According to the geographic layout of the region, no international waters exist within this specific corridor.
While the United Nations Convention on the Law of the Sea guarantees transit passage rights and prohibits the blockade of commercial shipping, Iran does not recognize this stance. The proposed circular route replaces traditional multi-lane transit with a one-way loop. Vessels entering the Persian Gulf will transit via the northern corridor, while return journeys will utilize the southern corridor near Oman.
Proposed Transit Model Mechanics
Under the framework revealed by the ministry press secretary, the circular route functions as a temporary management solution until a permanent agreement is reached. Cargo ships and tankers will pull into ports in Iran or other Persian Gulf nations before utilizing the southern path for departure. This operational shift addresses core disagreements over shipping rights in the strategically vital chokepoint.
Did you know? The Strait of Hormuz is one of the world’s most critical energy transit chokepoints, connecting major Middle Eastern oil producers to global markets.
Impact on Freedom of Navigation and Regional Control
The planned system restricts free navigation compared to conditions prior to the U.S.-Iran military conflict. According to officials, Iran could gain the authority to control which vessels and nationalities enter the strait. Furthermore, the operational framework indicates that passage could be explicitly denied to warships.

In June, the United States and Iran concluded an interim framework agreement. This accord stipulates that Tehran must coordinate with regional coastal states and negotiate directly with Oman regarding the future administration of the strait.
Frequently Asked Questions
How does the proposed circular shipping route work in the Strait of Hormuz?
Inbound tankers and cargo ships enter via a northern route through Iranian territorial waters. After calling at ports in Iran or the Persian Gulf, vessels use a southern route through Omani territorial waters for their return journey.
Why are there no international waters in the Strait of Hormuz?
The strait is roughly 39 kilometers wide at its narrowest point. Because both Iran and Oman claim 12-nautical-mile territorial zones, their waters overlap, leaving no corridor of international waters.
What international convention applies to transit rights here?
The UN Convention on the Law of the Sea guarantees transit passage and prohibits commercial blockades, though Iran does not recognize this framework.
Could military vessels be barred from the strait?
Yes. The new regulatory framework under discussion would allow Iran to restrict entry based on flag states and potentially deny passage to warships.
