From electric vehicles to advanced defence systems, rare earth elements (REEs) sit at the centre of the 21st Century economy. Demand for magnet rare earths – neodymium, praseodymium, dysprosium, and terbium – has nearly doubled between 2015 to 2024. As economies boost electrification and strengthen defence postures, REEs have moved from niche inputs to strategic commodities.

For investors, the REE market offers a complex opportunity set, defined by concentrated supply, demanding technological barriers as well as trade fragmentation and new industrial alliances. The coming decade will determine whether global supply chains can diversify meaningfully from China.

China produces the majority of mined output, and an even greater share of refined and processed materials, both conveying powerful geopolitical leverage.

When Beijing tightened export licence requirements in 2025, rare-earth magnet exports fell sharply, forcing manufacturers in several regions to pause production. Risks run deep as suppliers several tiers down within global value chains rely on Chinese-processed materials, making supply shocks difficult to hedge.

The market has seen this before in 2010 when reduced Chinese exports to Japan triggered a tenfold price spike and governments responded with force.

The United States has launched an expansive critical-minerals strategy with Project Vault, a $12bn mineral stockpile programme which sits alongside multi-billion dollar federal investment in domestic producers and a proposed critical minerals alliance with partner nations. The objectives are clear: reduce reliance on China, re-shore advanced manufacturing, and secure materials essential to defence, electrification, and AI infrastructure.

Brussels is preparing a Strategic Partnership Roadmap with the US to co-develop diversified non-China supply chains. Internally, the Critical Raw Materials Act (CRMA) mandates by 2030 a 10% domestic extraction, 40% domestic processing, 25% domestic recycling and a cap of 65% reliance on any single external supplier.

The RESourceEU plan, adopted in 2025, aims to mobilise €3bn to expand recycling capacity, restrict magnet scrap exports, establish a European Raw Materials Centre, and support joint purchasing and stockpiling, signalling Europe’s powerful pivot toward resource security.

Collectively, these actions will erode China’s dominance over time, but rebalancing of supply chains will take many years of sustained progress. Beyond China, supply is broadening. Australia remains a leading rare earth refiner through Lynas and is expanding midstream capacity. Norway has discovered Europe’s largest known REE deposit, signalling diversification potential. Brazil is drawing investor attention due to geological endowment and policy shifts encouraging foreign involvement.

Yet these opportunities come with realities that investors must factor in, including long development timelines, high capital intensity, environmental scrutiny, and the technical difficulty of scaling separation and processing capacity.

A promising development worldwide is the rise of secondary REE supply via recycling. Under IEA forecasts, recycled rare earths could supply up to 20% of total demand by 2050, with secondary output tripling in key scenarios. Recycling offers distinct strategic advantages including a lower environmental footprint than mining, faster scalability, and reduced exposure to geopolitical supply shocks.

Governments across the EU, US, Japan, and South Korea are supporting recycling innovation, with investment flowing into startup ecosystems. In 2025 alone, US venture capital funding for REE recycling start-ups accelerated to $628m, an increase of nearly 3,000% – an early sign of supply-side innovation.

For investors evaluating REEs through a global lens, the risks are clear. Processing capacity remains extremely concentrated, policy shifts can trigger sharp price volatility, new mines and refineries take years to deliver, and trade tensions can disrupt flows.

The opportunity set spans the capital structure. Listed developers and producers across Australia, the US, and Asia offer equity exposure, though investors need to be attentive to valuations. Bonds and project-finance instruments tied to government-supported strategic projects present another route, with policy backing altering risk profiles. Circular economy businesses focused on magnet recycling and manufacturing introduce growth exposure with a different risk mix.

Currency considerations also matter. Many REE-exposed equities and bonds are not EUR-denominated. For European investors allocating outside their base currencies, exposure can create both risk and diversification potential.

Rare earth elements have emerged as foundational to the next era of industrial development. As nations race to build resilient supply chains, REEs now sit at the intersection of technology, geopolitics, and capital markets.

For investors, the long game is broader than a peripheral bet on specialised mining companies; it is a strategic investment theme shaped by government policy, international alliances, sustainability innovation, and long-duration demand growth.

The next decade will determine whether global markets can diversify supply, or whether concentration will deepen. Either way, investors who understand geopolitical dynamics, technological pathways, and evolving industrial policies stand to benefit most from one of the defining commodity stories of our time.
