This escalation follows moves by the Persian Gulf Waterways Management Authority to restrict vessels that deviate from Tehran's designated routes. The authority has begun listing non-compliant charterers on a Non-Compliance List, prompting some shipowners to send formal apology letters to secure future passage. President Masoud Pezeshkian previously called the restriction of the strait a natural response to US sanctions and stated it would remain open only if negotiations resolve the current dispute.
