Episode notes
Iran's Threats Have Functionally Closed The Waterway
- Iran's Revolutionary Guard warnings and threats to set ablaze any tanker have effectively halted shipping even without a formal closure.
- For shipowners and insurers the threat equates to closure, leaving around 200 tankers stuck in the strait.
Market Reaction Was A Sharp Price Spike Then Emergency Releases
- Oil prices spiked, briefly reaching about $116 a barrel and earlier touching $100, as markets reacted to transit disruption.
- The IEA coordinated emergency releases of strategic stocks to cool prices and partially reverse the spike.
IAE Calls This The Biggest Oil Supply Shock Ever
- The IEA called this the largest oil supply shock in history, requiring a bigger strategic stock release than after Russia's 2022 invasion of Ukraine.
- Analysts like Goldman Sachs estimate closing the strait has many times the impact of Russian export disruption.
