Iran and Oman have agreed to form a joint working group to manage navigation and discuss service charges for ships in the Strait of Hormuz.

This agreement marks a significant diplomatic shift in the management of one of the world's most critical oil transit chokepoints. By coordinating control and potential fees, the two nations seek to formalize their authority over the waterway's traffic.

During talks held in Muscat, Oman, the two countries reaffirmed their sovereign rights over the strait [1, 2]. The discussions focused on ensuring safe navigation and the joint management of the strategic waterway [3, 5].

A key component of the new arrangement involves the pursuit of talks regarding service charges for vessels transiting the strait [1, 3]. These reports first surfaced on June 18, 2026 [1].

The joint working group will serve as the primary mechanism for coordinating these efforts [2]. Officials from both nations said the talks were constructive as they sought to balance security needs with the economic interests of international shipping [5].

Control over the Strait of Hormuz has long been a point of international tension. The decision to implement service charges could affect global shipping costs if the measures are enacted on a broad scale [3].

Iran and Oman have agreed to form a joint working group to manage navigation.

The move to establish a joint working group suggests a strategic alignment between Iran and Oman to exert more direct control over the Strait of Hormuz. By discussing service charges, these nations are signaling a shift toward treating the waterway as a managed economic asset rather than just a transit corridor, which may increase costs for global energy shipments and challenge existing international maritime norms.
