U.S. Grants OFAC Power to Sanction Anyone in Iranian Shipping Worldwide

On August 24, 2026, the U.S. Treasury issued a shipping sectoral determination letting OFAC sanction any person operating in Iranian shipping regardless of location. No nexus to U.S. persons or the U.S. financial system is required. Shipowners, charterers, insurers, and port authorities worldwide now face sanctions risk for any Iranian shipping connection.
