The US has revoked a waiver that had allowed new sales of Iranian oil, according to Bloomberg, after carrying out strikes on more than 80 sites in Iran. The move adds a sanctions and security dimension to an already fragile ceasefire environment and directly raises the stakes for crude tanker movements linked to Iranian exports.

For TankerMap users, the key issue is the knock-on effect on flows through the Strait of Hormuz after recent attacks on ships there. Any tightening of restrictions on Iranian oil sales, combined with renewed military action, can alter loading patterns, voyage risk assessments, insurance costs and regional routing across one of the world’s most important oil chokepoints.
