Episode notes
Straits Of Hormuz Is A Critical Oil Chokepoint
- The Straits of Hormuz is a strategic 33km-wide chokepoint that funnels about 20% of global oil and 35% of seaborne oil through narrow two-way lanes.
- Piers Curran notes that disruption there quickly pushes global energy prices higher because so much Gulf oil and gas must transit this tiny corridor.
US Shale Didn't Remove Gulf Influence
- Despite US shale growth to ~13mbpd, Gulf nations still supply roughly 20% of global oil because Asian demand (China, India, Japan) relies on seaborne Gulf exports.
- Piers Curran highlights that the strategic dependency shifted from West to East rather than disappearing.
Brent Spike Pulls WTI Higher Too
- Brent (Middle East/Europe/Asia benchmark) rose sharply from ~$60 at Christmas to mid-$80s after the Iran flare-up, while WTI (US benchmark) also climbed due to global price correlation.
- Piers Curran explains the Brent-WTI spread widened because Brent saw the bigger supply risk but WTI still moved up to affect US pump prices.
