What to know about rare earths in the China-U.S. trade dispute

China's export restrictions on seven rare earth metals and magnets since April, a response to prior U.S. tariffs, are disrupting U.S. supply chains, particularly impacting defense, energy, and automotive sectors, as the U.S. relies heavily on China for both mining and processing of these critical minerals. While the Pentagon has invested heavily in establishing a domestic supply chain, U.S. production remains in its early stages; meanwhile, China controls 70% of the world's rare earth mining and 90% of processing. The situation has spurred increased investor interest and innovation in the rare earth mineral sector.

Analysis

China's imposition of export restrictions on seven critical rare earth metals and magnets since April, including samarium, gadolinium, and terbium, presents a significant challenge to U.S. supply chains, particularly impacting the defense, energy, and automotive sectors. These restrictions, which the Center for Strategic and International Studies (CSIS) identifies as a response to U.S. tariff increases, underscore China's dominance in the sector, where it controls approximately 70% of global rare earth mining and 90% of processing. This action follows a similar ban in the previous year on gallium, germanium, and antimony directed at the U.S. after curbs on the Chinese chip industry. The U.S. recognizes this reliance as a national security risk, prompting a Trump administration investigation and over $439 million in Pentagon investment since 2020 to develop a domestic supply chain; however, U.S. production capabilities remain in their nascent stages according to CSIS. The strategic importance of these minerals, which possess unique fluorescent, conductive, and magnetic properties, is further highlighted by their role in the Ukraine conflict, where the U.S. sought, but was denied, a 50% ownership stake in Ukraine's rare earth reserves in exchange for investment. Consequently, these geopolitical tensions and supply disruptions have catalyzed a surge in investor interest and the emergence of startups focused on rare earth mineral innovations.

Key Decisions for Investors

• Investors should closely monitor evolving U.S.-China trade relations and any further export controls on critical materials, as these directly impact supply stability and pricing for rare earths.
• Consider exploring investment opportunities in companies engaged in domestic U.S. or allied-nation rare earth mining, processing, recycling, or developing alternative technologies, while acknowledging the early-stage nature and associated risks of these ventures.
• Evaluate portfolio exposure to industries heavily reliant on rare earths, such as defense, electric vehicles, and renewable energy, and assess potential supply chain vulnerabilities and cost implications stemming from these geopolitical developments.
