Episode notes
Strait Of Hormuz Controls Global Oil Flow
- The Strait of Hormuz is a critical narrow chokepoint that normally carries about 20% of the world’s petroleum exports.
- Ellen Wald explains most Persian Gulf oil must transit this difficult, narrow waterway, so stoppages sharply cut global supply.
Use IEA Reserves To Calm Markets
- Governments can ease a supply shock by coordinating releases from IEA strategic reserves to flood refineries and lower prices.
- Ellen Wald notes every IEA member must hold 90 days of imports and a coordinated release is a ready tool not yet used.
Insurance And Proximity Are Halting Tankers
- Tankers avoid the Persian Gulf due to high insurance and drone/missile risk near Iran’s coastline, raising transport costs and halting flows.
- Wald suggests moving shipping lanes farther from Iran or ending the conflict to reduce risk and restore transit.
