Tehran has declared it will not issue permits for vessel passage through the Strait of Hormuz as long as the United States continues its strikes against Iran.
The statement, reported by the Fars news agency, hardens the conditions for reopening the critical waterway, linking maritime access directly to the cessation of hostilities rather than a broader diplomatic resolution.
The declaration follows earlier warnings from Iran’s Islamic Revolutionary Guard Corps, which had already signaled that the strait would remain closed to maritime traffic until Washington ended what it described as acts of aggression.
By formalizing the refusal to issue transit permits, Iranian authorities are reinforcing the operational blockade that has effectively halted commercial shipping through the corridor.
Markets have already begun pricing in the severe disruption to global energy flows.
Greek shipping equities surged earlier in the session as the maritime risk premium widened, reflecting investor anxiety over route exposure and potential supply chain fractures.
