China's Rare Earth Export Controls: A Threat to Global Supply Chains

China's Rare Earth Strategy

• 🇨🇳 China has begun restricting exports of critical rare earth minerals, a move that began on April 4th with seven materials and expanded to five more recently.
• 💡 These restrictions target specific rare earths crucial for commercial and military technology, which constitute a small percentage of overall rare earth deposits.
• 🎯 China views rare earths as a national treasure, similar to how the Middle East views oil, and is strategically holding onto these materials.

Impact on US and Global Markets

• ⚠️ The restrictions could lead to significantly lower prices for bulk rare earths like cerium, lanthanum, and neodymium, making it difficult for new mines, including US-based ones like Mountain Pass, to operate profitably.
• 📉 This strategy might force new mines to rely on government subsidies to remain operational.
• ⚡ The fallout could impact various industries, including electric cars (due to dysprosium in magnets) and laser technology.

US Response and Future Considerations

• 🇺🇸 The US government has been advised to consider subsidizing domestic mines like Mountain Pass to ensure a supply of critical heavy rare earths essential for military applications.
• ⛰️ While the US has deposits of some heavy rare earths, it lacks the ionic clay deposits found in China, which are rich in these critical materials.
• ⚖️ Historically, China has used pricing strategies, including creating price differentials between domestic and international markets, to encourage manufacturing to move to China, a practice that has led to WTO actions.
• 🤝 There is a trend towards sovereign control over rare earth materials, with potential government involvement and subsidies for domestic mining operations, as seen with the US government taking a majority share in Mountain Pass.
