Iran said Saturday that it is closing the Strait of Hormuz and that no vessels will be allowed to pass until foreign interference ends, according to Bloomberg Markets, citing state-run IRIB News. The statement directly targets one of the world’s most important tanker chokepoints, through which large volumes of crude oil, refined products and LNG normally move between the Gulf and global markets.

For tanker owners, charterers and energy traders, any claimed closure of Hormuz immediately raises risks for vessel routing, port operations, cargo timing and freight costs across the Gulf region. TankerMap flow monitoring will be closely watched for signs of delays, vessel clustering, reduced transits or diversions affecting oil and gas shipping linked to Gulf export terminals.
