Episode notes
Strategic Reserves Define Short Term Risk
- Strategic reserves and import sources determine imminent vulnerability to supply disruptions.
- Australia, Indonesia and Thailand have low strategic oil reserves and therefore higher short-term risk if shipments halt.
China Has Diversified Away From Iran
- Supply diversification reduces reliance on Iran for China despite media narratives.
- Iran supplies only about 5% of China's oil imports as China has diversified sources in recent years.
Hidden Input Dependencies Threaten Manufacturing
- The conflict is revealing fragile supply chains beyond oil, affecting inputs like fertilizers and helium.
- Sectors such as semiconductors rely on helium and some Chinese industries get 40% of a key input from Iran, creating concentrated risks.
