Chinese exports of two critical minerals plunge even as rare earths rebound

China's exports of critical minerals antimony and germanium plummeted 88% and 95% respectively in June versus January, reaching near-record lows. This sharp decline stems from an intensified crackdown on smuggling and transshipment by Chinese authorities, including the spy agency, following export controls imposed in 2023-24 and a December ban on U.S. exports. Unlike rare earths, these vital materials, crucial for weapons, telecommunications, and solar cells, have not seen a rebound, leading to significant market impact with high-purity germanium prices doubling and antimony prices nearly quadrupling since the controls.

Analysis

China's exports of the critical minerals antimony and germanium have experienced a severe contraction, with June volumes plummeting 88% and 95% respectively from January levels. This decline is not a market-driven event but a direct result of an intensified government crackdown on smuggling and illegal transshipment, enforced by China's top spy agency to uphold export controls implemented in 2023 and 2024. Unlike the situation with rare earths, where exports rebounded following a U.S.-China agreement, the supply of antimony and germanium remains constricted at near-record lows, indicating a more targeted and persistent enforcement action. This has had a dramatic effect on global prices, with high-purity germanium more than doubling since July 2023 and antimony prices nearly quadrupling since May 2023. The collapse in exports to transshipment hubs like Thailand and Mexico, down 90% and 100% respectively since April, confirms the effectiveness of the crackdown and signals a significant, long-term disruption to the supply of materials vital for the weapons, telecommunications, and solar industries.

Key Decisions for Investors

• Investors should assess exposure to companies in the defense, telecommunications, and solar sectors for vulnerability to input cost inflation and production bottlenecks stemming from sustained antimony and germanium shortages.
• Consider opportunities in non-Chinese miners and refiners of these critical minerals, as well as in companies developing recycling technologies, which stand to benefit from the search for alternative supply chains.
• Monitor geopolitical developments between the U.S. and China closely, as the targeted and persistent nature of these export controls represents a significant source of systemic risk and price volatility in strategic commodity markets, distinct from previous trade actions.
