The U.S. has revoked its temporary sanctions waiver for Iranian oil exports following renewed attacks on commercial shipping in the Strait of Hormuz, according to gCaptain. The move was announced alongside new U.S. military strikes against Iran, tightening the link between regional security tensions and oil trade restrictions.

For tanker markets, the immediate focus is Hormuz, one of the world’s most important crude and products transit routes. Any escalation around the strait can raise voyage risk, insurance costs and routing uncertainty for ships loading in the Gulf, while stricter limits on Iranian barrels may further affect regional export flows and sanctioned shipping activity.
