Iran has designated its own shipping corridors in the Strait of Hormuz, creating two competing lanes for maritime traffic.
This development signals a push by Tehran to assert sovereignty over one of the world's most strategic waterways. By controlling the flow of ships and negotiating a payment system with Oman, Iran aims to challenge the naval presence and warnings of the U.S.
An analysis of vessel movements from June 18, 2026 [1], indicates that many ships are now following routes set by Iranian authorities. This shift has effectively split the strait into two distinct lanes. While Iranian boats monitor and control their designated corridor, U.S. naval forces continue to escort tankers through a separate, established international lane [2].
Reports indicate that Iranian forces have maintained a high level of aggression toward vessels that do not adhere to these new designations. In some instances, Iranian boats have fired on ships located in the non-Iranian lane [2].
Tehran's strategy involves more than just physical control of the water. The Iranian government is currently in talks with Oman to establish a formal ship payment system [3]. This move would allow Iran to collect transit fees from vessels passing through the strait, a direct defiance of U.S. efforts to keep the waterway open and free from unilateral tolls [3].
This tension follows a history of volatility in the region. On April 23, 2024 [4], Iran seized a vessel within the strait, highlighting the ongoing risk to commercial shipping. The current split in lanes reflects a broader geopolitical struggle for dominance over the Persian Gulf's exit point.
U.S. military sources said that their forces remain committed to escorting tankers to ensure the safe passage of energy supplies [2]. However, the increasing number of ships opting for Iranian-designated routes suggests that commercial interests are adapting to the reality of Iranian control on the ground [1].
“Iran is designating its own shipping corridor and negotiating a fee system.”
The creation of parallel shipping lanes represents a transition from sporadic disruptions to a systemic attempt by Iran to monetize and regulate the Strait of Hormuz. By establishing a fee system and designating routes, Tehran is attempting to create a 'de facto' administrative control over the waterway. This forces international shipping companies to choose between U.S. military protection and Iranian regulatory compliance, potentially increasing the cost of global energy transport.
