Iran-U.S. Hormuz counterproposal follows three tanker strikes — USO event-vol reprices chokepoint risk
Question
Iran-U.S. Hormuz counterproposal follows three tanker strikes — USO event-vol reprices chokepoint risk
Direct answer
Three vessels were struck in the Strait of Hormuz while Iran received a formal U.S. response on a ceasefire and reopening the chokepoint, creating binary crude risk around escalation versus restored transit. A verified ceasefire and uninterrupted tanker passage would crush the event premium and invalidate the straddle. — bearish pressure on USO.
