Iran and Oman are actively discussing a permanent security mechanism for the Strait of Hormuz. Iran is pushing to institutionalize and normalize a transit fee or toll on commercial shipping vessels navigating the narrow waterway. According to an Iranian diplomatic envoy, the proposed system is designed to secure the long-term positioning of Iran and Oman as the primary regulators of the strait, effectively transforming a temporary leverage point from the recent military conflict into a permanent sovereign right.
To formalize its grip, Iran’s newly established Persian Gulf Straits Authority began applying conditional rules and hefty transit tolls, in some cases exceeding one million dollars per vessel, while granting selective exemptions to friendly nations like Russia or China. By engaging Oman, which shares territorial jurisdiction over the Strait, Iran is seeking to build a coalition that validates these tolls under the guise of funding localized maritime security.
The US maintains an opposing view on the matter, viewing the permanent toll as a non-negotiable barrier to reaching a sustainable peace deal. Under the United Nations Convention on the Law of the Sea, international straits are governed by transit passage protocols that guarantee the uninterrupted flow of global commercial shipping, a principle the US insists must be restored without conditions.
The US has treated the removal of these tolls as a core prerequisite for reaching a peace deal. President Trump has warned international maritime firms that paying Iran’s transit fees could trigger severe economic sanctions. The US military has also enforced its own counter-blockade on Iranian ports and continues to intercept or redirect vessels to challenge Tehran’s claims of total sovereignty.
