    Question

    US Treasury widens sanctions on Iran and targets 60 individuals, entities and vessels

    Direct answer

    The measures directly tighten pressure on Iranian crude and product export channels, raise counterparty risk for regional shippers and banks, and helped push Brent and WTI lower as traders judged the move less disruptive to near-term supply than a military escalation.
