New ETF Targets Rare Earth Investments Outside China Amid Geopolitical Supply Concerns
The launch of the Sprott Rare Earths Ex-China ETF reflects growing efforts to diversify rare earth supply chains away from Chinese dominance, addressing national security and green energy vulnerabilities.
China maintains control over approximately 60% of global rare earth mining and 80% of processing, according to a 2025 report from Resources for the Future, creating significant supply chain vulnerabilities for Western industries and military applications. The geopolitical tensions between the U.S. and China, highlighted by tariff disputes and China's October threat to restrict rare earth exports, have underscored the strategic importance of developing alternative sources for these critical materials.
Rare earth elements, a group of 17 chemically similar metals including 15 lanthanides, are essential components in modern technologies ranging from electronics and renewable energy systems to defense applications. They are used in magnets, batteries, and catalysts, making them indispensable for electrification and semiconductor manufacturing. Despite their name, some rare earth elements are relatively abundant in the Earth's crust, but China's processing dominance creates supply concentration risks.
The recently launched Sprott Rare Earths Ex-China ETF (NASDAQ: REXC) represents a financial instrument designed to address these concerns by providing investors exposure to rare earth companies operating exclusively outside China. This fund tracks the Nasdaq Sprott Rare Earths Ex-China Index and invests in companies generating at least 50% of revenues from rare earth and strategic metals. As Sprott reports, it's the first ETF with such a focus, adding to their existing suite of critical materials funds including the Sprott Critical Materials ETF (NASDAQ: SETM).
Senator Marco Rubio highlighted the national security implications in a 2019 speech, noting the paradox of an industry critical to national interest being dominated by a geopolitical competitor. "For decades, we enjoyed a broad consensus that, once China became rich, they would become more like us - more democratic and respectful of the rules that govern international trade and commerce," Rubio stated, pointing to the strategic vulnerability created by rare earth dependence.
The ETF's structure emphasizes companies strengthening Western supply chains, with significant exposure to small- and micro-cap firms and emerging-market issuers typically involved in producing elements like cerium. While offering diversification and hedging opportunities for retail investors, the fund carries substantial risks as noted in its prospectus available at https://sprottetfs.com/rexc/prospectus, including volatility and concentration in specialized industries with strained supply-demand dynamics.
As industries and governments seek to reduce reliance on Chinese rare earths, financial instruments like REXC represent one approach to supporting alternative supply chain development. The fund rebalances quarterly and is available through online brokerages, providing accessible exposure to a sector increasingly viewed through both economic and national security lenses.
