U.S. Treasury Warns Oman Over Hormuz Toll System

U.S. Treasury Secretary Scott Bessent has issued a stern warning to Oman regarding an Iranian-linked tolling system operating within the Strait of Hormuz. This illicit mechanism threatens global maritime security by attempting to levy fees on commercial vessels transiting this critical chokepoint. Washington has signaled its intent to aggressively sanction any entity facilitating these payments, which are viewed as a direct violation of international maritime law and a potential funding source for regional instability affecting global shipping lanes.

The imposition of unauthorized tolls directly contravenes the United Nations Convention on the Law of the Sea (UNCLOS), specifically regarding the right of transit passage through international straits. From a compliance perspective, these demands conflict with SOLAS Chapter XI-2 and the ISPS Code, which require masters to maintain strict security protocols against external interference. Shipping companies must ensure their Safety Management Systems (SMS) are updated to address these extortion risks, as paying such tolls could trigger severe violations of U.S. Office of Foreign Assets Control (OFAC) regulations and international anti-money laundering frameworks.

Masters and navigating officers must remain hyper-vigilant when transiting the Strait of Hormuz. If approached by unauthorized entities demanding toll payments, bridge teams should immediately notify their company security officer and flag state authorities. Navigating officers must prioritize vessel safety and security over compliance with illegal demands. Documentation of any such interaction is critical for legal protection, and crews should avoid any financial transactions that could lead to secondary sanctions against their vessel or operating company.
