Episode notes
Why Teapot Refineries Buy Iran's Sanctioned Oil
- Chinese teapot refineries became the main buyers of Iranian crude because sanctioned barrels are cheap and the small firms can stomach sanctions risk better than state majors.
- Erica Downs says national oil companies need dollar access, while teapots in Shandong may depend on discounted Iranian crude for survival.
How Teapots Shifted Into a Sanctions Arbitrage Trade
- China's teapot refiners only got crude import licenses in 2015 after meeting cleanup and storage requirements set by Beijing.
- Erica Downs says they first bought from many countries, then drifted toward Iran, Russia, and Venezuela as sanctions created attractive discounts.
China Entered the Shock With a Large Oil Buffer
- China can absorb short-term oil disruption because strategic and commercial stockpiles cover about 120 days of net crude imports.
- Erica Downs also notes floating storage near China and Malaysia plus bonded oil in Chinese ports that can be tapped quickly.
