Episode notes
Escalation Raises Market Risk
- Recent headlines and military buildup have raised market perception of oil-supply risk despite Brent near $67.
- Clayton Seigle links rhetoric and assets in the region to increased disruption probability if hostilities resume.
12-Day War Showed Restraint
- During last June's 12-day war, Gulf oil exports avoided major disruption even as Iran and Israel clashed.
- Iran perceived no existential threat because its exports continued, so it avoided targeting Arab Gulf oil assets.
Blocking Iranian Shipments Lifts Prices
- Seigle outlines Scenario 1: U.S. or Israel disrupts Iranian crude shipments, mainly at Karg Island.
- Such action could remove 1.6 mb/d of Iranian exports and raise global prices by roughly $10–$12 as China seeks substitutes.
