US-Iran tanker attacks lift Brent more than 2% in Hormuz — USO reprices chokepoint supply risk
Question
US-Iran tanker attacks lift Brent more than 2% in Hormuz — USO reprices chokepoint supply risk
Direct answer
Two tanker attacks in the Strait of Hormuz and fresh US-Iran strikes pushed Brent and WTI higher by more than 2%, adding a transit-risk premium to crude. The trade is invalidated if shipping lanes remain open without further incidents and Qatar-led talks de-escalate retaliation risk. — bullish pressure on USO.
