On Tuesday, as UKMTO reported another projectile strike on a commercial vessel, Iranian parliamentary speaker Mohammad Bagher Qalibaf reiterated that Tehran will keep the waterway closed until Washington meets a list of conditions.<\/p>\n<p>Qalibaf said the Strait of Hormuz will not reopen until the United States fulfills commitments including lifting the naval blockade, releasing frozen assets, lifting oil sanctions, ending threats and military operations \u201con all fronts,\u201d and implementing other agreed conditions. Washington continues to enforce a naval blockade on Iranian port traffic while commercial AIS counts remain in the single digits versus more than 130 daily transits before the February war.<\/p>\n<h2>Separate Oman Talks, Same Crew Risk<\/h2>\n<p>Iran and Oman are still discussing a navigation-management arrangement and have said they are finalising details for a joint statement. That track does not, by itself, restore safe commercial transit. For masters and CSOs, an expired MoU plus an active projectile threat means any Hormuz nomination remains a high crew-safety decision, not a routine routing choice.<\/p>\n<p>Egyptian diplomats separately suggested an Iran\u2013Oman deal could reopen space for broader U.S.\u2013Iran talks, but operators should not treat diplomatic headlines as clearance to sail.<\/p>\n<h2>What Operators Should Note<\/h2>\n<ul>\n<li><strong>Do not treat MoU expiry as a temporary gap<\/strong> \u2014 plan for sustained dual-control and kinetic risk.<\/li>\n<li><strong>Separate Iran\u2013Oman corridor talks from verified safe-transit guarantees<\/strong> before accepting fixtures.<\/li>\n<li><strong>Keep charter-party war-risk and deviation clauses aligned<\/strong> with indefinite Hormuz closure language.<\/li>\n<li><strong>Prioritise seafarer refusal-of-work and ISM risk-assessment records<\/strong> if owners face commercial pressure to transit.<\/li>\n<\/ul>\n<p>RegulAs Shipping will track any renewed MoU, Oman joint statement, or official corridor guidance as it appears.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The U.S.\u2013Iran memorandum aimed at easing Hormuz hostilities expired on 17 August.
