U.S. Bans 'Safe Passage' Agreements Between Shipping Firms and Iran

The U.S. Treasury Department warns that even non-cash agreements for maritime deconfliction in the Strait of Hormuz violate current sanctions.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has issued a new directive prohibiting any arrangements with Iran intended to secure "safe passage" through the Strait of Hormuz. This update clarifies that U.S. sanctions apply to these agreements even if no financial compensation is exchanged. The measure is designed to close informal maritime deconfliction channels that shipping companies may use to avoid interference from Iranian forces. The directive places significant pressure on global shipping insurers and operators, who often navigate high-risk regional waters. By categorizing non-cash "immunity" arrangements as sanctions violations, the Trump administration is seeking to block intermediaries from negotiating separate peace or transit deals with the Islamic Revolutionary Guard Corps (IRGC) or other Iranian authorities. This reinforces the broader U.S. strategy of maximum economic pressure and centralized control over maritime security protocols in the Persian Gulf.
