US Rare Earth Breakaway From China Still a Decade Away

The United States is confronting a far more entrenched rare earth dependency problem than its recent political rhetoric suggests. Over the past year, President Donald Trump has pushed an aggressive agenda aimed at breaking China’s dominance over the critical minerals that underpin modern industry and military power. He has promised rapid independence, even suggesting last November that the US could sever its reliance within 18 months. But projections compiled from multiple consultancies and industry data indicate the timeline is far more likely to stretch into the next decade, particularly for the most strategically important materials.

At the center of the issue is a stark divide between two categories of rare earths: the more abundant light elements used in consumer electronics and the far scarcer heavy rare earths essential for high-performance magnets, defense systems and electric vehicles. While some light rare earth supply chains outside China are expected to improve by the end of the decade, heavy rare earths such as dysprosium and terbium remain overwhelmingly controlled by Chinese production. Data from McKinsey & Co., CRU Group and Benchmark Mineral Intelligence suggest that even by 2035, countries outside China may still meet less than a fifth of global demand for these critical inputs, leaving a persistent structural deficit.

The stakes are significant because rare earths sit at the core of roughly 4% of US gross domestic product, or about $1.2 trillion in economic activity, according to Bloomberg Economics estimates cited in Bloomberg reporting. Industries ranging from aerospace and defense to semiconductors, transportation and energy all depend on these materials. A sustained supply disruption could therefore ripple through multiple sectors simultaneously, affecting everything from fighter jets and submarines to electric vehicles and industrial machinery.

In response, Washington has accelerated efforts to build an alternative supply chain almost from scratch. The Pentagon has signed agreements with firms such as Australia’s Lynas Rare Earths Ltd., one of the few non-Chinese companies capable of refining heavy rare earths. US-based MP Materials Corp. operates the country’s only active rare earth mine at Mountain Pass, California, and is expanding downstream into magnet production. Yet despite billions of dollars in public and private investment, output remains tiny compared with global demand. Lynas, for instance, produced only a handful of tons of key heavy elements in early 2026, while global demand runs into thousands of tons annually.

The core challenge is not simply mining, but the extraordinary complexity of refining and separating rare earth elements. China dominates every stage of the value chain, from extraction to chemical separation and magnet manufacturing, with its strongest advantage in the highly specialized refining process required for heavy rare earths. These elements are chemically similar, making separation slow, capital-intensive and dependent on decades of accumulated technical expertise. China’s dominance is reinforced by extensive patent holdings, deep industrial clustering and a workforce of thousands of trained specialists, compared with fewer than a hundred in the United States, according to academic estimates cited in Bloomberg reporting.

This technical barrier is compounded by cost advantages. Chinese producers benefit from vertically integrated supply chains that allow them to undercut global competitors, often triggering price swings that destabilize emerging projects elsewhere. Historical episodes, such as Beijing’s export restrictions in the early 2010s, temporarily raised global prices and spurred investment outside China. But once new supply entered the market, prices fell again, making it difficult for higher-cost producers in the West to remain viable. This cyclical dynamic continues to deter large-scale investment despite growing geopolitical urgency.

Efforts to diversify supply chains are also being shaped by geopolitics and shifting alliances. Japan, which has spent more than a decade reducing its dependence on China, still sources a majority of its rare earth supply from Chinese producers, particularly for heavy elements. The United States and its allies have discussed forming a coordinated “critical minerals” bloc to stabilize pricing and secure supply, but progress has been uneven. Countries such as Japan and several European economies remain cautious about antagonizing Beijing, while concerns persist that price floors or trade interventions could distort markets and increase costs.

At the same time, new frontiers are emerging outside traditional supply hubs. Brazil, which holds some of the largest rare earth reserves outside China, is being positioned as a potential alternative source of heavy elements. Projects in Minas Gerais are exploring ionic clay deposits similar to those in China and Myanmar, with early estimates suggesting meaningful production potential by the end of the decade. However, infrastructure gaps, bureaucratic hurdles and the absence of an integrated industrial strategy continue to slow development.

Even if these initiatives succeed, analysts caution that they are unlikely to fully close the gap. Benchmark Mineral Intelligence expects China and Myanmar alone to account for nearly 80% of global dysprosium and terbium supply in the early 2030s, while CRU Group projects that most new Western projects will come online too late to offset near-term bottlenecks. Meanwhile, Bloomberg Economics and industry researchers warn that even partial disruptions in supply could force temporary shutdowns in key manufacturing sectors, highlighting the fragility of current industrial dependencies.

The rare earth challenge reflects not just a materials shortage but a deeper structural imbalance in global industrial power. China’s decades-long investment in mining, refining and magnet production has created a system that is difficult to replicate quickly, even with significant financial backing. As Bloomberg has reported, the United States is now deploying the full range of industrial policy tools—subsidies, equity investments and procurement guarantees—to catch up. But experts increasingly agree that this is a long-term competition rather than a short-term fix.

For now, the gap between political ambition and industrial reality remains wide. While Washington continues to pursue independence, projections suggest that China will retain decisive leverage over heavy rare earths well into the 2030s. As one analyst cited in Bloomberg reporting noted, even under the most optimistic scenarios, meaningful diversification will take far longer than policymakers expect, leaving the United States exposed to one of the most strategically important supply chain vulnerabilities in the global economy.
