America's billions cannot buy its way out of China's minerals trap

THE ANNOUNCEMENT of a $3 billion rare-earth deal was the sort of headline the Trump administration has been courting. In April 2026, USA Rare Earth, a firm that reported $1.6m in revenue last year, agreed to acquire Brazil's Serra Verde Group for almost $3 billion in stock and cash. The transaction gave it control of the Pela Ema mine in Goiás, the first large-scale producer outside Asia of the four magnetic rare earths—neodymium, praseodymium, dysprosium and terbium—plus yttrium, a mineral used in high-strength magnets. Mr Trump called the project part of a broader campaign to secure American supply chains. Whether the campaign will succeed is a different matter.

The $3 billion deal is not, in fact, the administration's biggest minerals play. It is only the most visible single transaction in a sprawling effort that the State Department claims has mobilised more than $30 billion in loans, investments and commitments over six months. There is also "Project Vault", a $12 billion strategic minerals stockpile announced in February, combining a $10 billion loan from the Export-Import Bank with private capital. The stockpile aims to hold a 60-day emergency supply of critical minerals, allowing American manufacturers to keep price risk off their balance-sheets, much as the Strategic Petroleum Reserve does for oil. Eleven new bilateral minerals agreements were signed at a February ministerial attended by 54 countries. An executive order in July tightened rules on defence contractors sourcing critical materials from geopolitical adversaries.

The ambition is understandable. In 2025, China accounted for over three-quarters of all growth in refined supply of key energy minerals, according to the International Energy Agency. It controls nearly 70% of global rare-earth mining and close to 90% of processing. Since 2005, China has accounted for over 90% of growth in global copper smelting, raising its share of global capacity from roughly 15% to half. In April 2025, Beijing imposed export controls on seven heavy rare-earth elements; in October those controls expanded to cover products made with Chinese rare-earth processing technology. The incentive structure is clear. A state that controls processing can throttle exports, suppress prices when it wishes, and use supply as geopolitical leverage. The 2025 restrictions did exactly that, disrupting allied defence and industrial supply chains within weeks.

So is the American response adequate? To be sure, there is real progress. Bloomberg Intelligence projects China's market share in rare-earth processing falling from 90% to 69% over the coming years as non-Chinese projects come online. Serra Verde's Brazilian production alone could represent over half of the total non-China heavy rare-earth supply by 2027. The US has invested billions in domestic miners, recycling facilities and magnet factories. These are not vanity projects.

Yet the trouble is that diversification by sheer replication is the wrong strategy. The IEA reports that refining projects outside China face capital costs 20% to 150% higher and operating costs roughly 50% higher on average. Diversifying the full magnet supply chain would require approximately $60 billion in investment over the next decade. The Council on Foreign Relations, an American think-tank, put it bluntly in a February 2026 report: the United States cannot "out-mine, out-process, and outspend China". The Chinese advantage is not merely geological; it is industrial, built over three decades of scale, infrastructure, tolerated environmental damage and an integrated supply chain from mine to magnet. Copying that model at five times the cost is not industrial policy. It is subsidised inefficiency.

The second problem is governance. The administration has not been content to provide loans, tax credits or regulatory relief—the familiar, if imperfect, tools of traditional industrial policy. It has taken equity stakes in private firms. The Department of Commerce invested $1.6 billion in USA Rare Earth, acquiring a stake that could exceed 15%. The Department of War provided $620 million in debt to Vulcan Elements, a company that then attracted scrutiny after it emerged that Mr Trump's son had invested in the firm before the Pentagon's money arrived. The administration has deployed more than $1 billion of taxpayer-funded equity in select mining and materials companies, including MP Materials, Lithium Americas, ReElement Technologies and Korea Zinc. Democratic lawmakers have asked for an accounting of revenue-sharing, returns on investment and market distortion. The worry is not hypothetical. When the government picks winners, those winners acquire a different kind of incentive. Competitiveness gives way to entitlement; innovation gives way to lobbying.

The third problem, which neither the White House nor most investors address, is that the race is not merely about mining. It is about what happens downstream. A mine in Texas or Brazil solves only the first link in a chain that runs through separation, metallisation, alloying, sintering and magnet manufacturing. China controls most of those downstream steps. Full implementation of Chinese rare-earth export controls, says the IEA, could put an estimated $6.5 trillion of annual downstream production outside China at risk. Building Western alternatives across every link is orders of magnitude harder than opening a single mine.

There is a better answer. The CFR report calls it "leapfrogging": scaling disruptive innovation, waste recovery and recycling rather than trying to match China's brute-force model. The United States has an advantage in materials engineering that China does not. Companies such as Niron Magnetics are building rare-earth-free iron nitride magnets and received government funding to construct a factory in Minnesota. Firms including Vulcan Elements and ReElement Technologies received combined debt and equity investments to scale domestic rare-earth recycling from electronic waste, with a North Carolina facility expected to open by 2027. The IEA projects that secondary supply—recycled materials—could double its contribution by 2040. Sodium-ion batteries, which use no lithium or cobalt, are advancing quickly.

The incentive for these alternatives is already improving. European prices for gallium and heavy rare earths are currently five times higher than Chinese domestic prices; germanium is three times higher. That divergence, reported by the IEA in its 2026 outlook, exists because Western producers cannot access Chinese markets on the same terms. It makes substitution and recycling economically attractive in a way they were not five years ago. The question is whether American policy will encourage these routes or whether the sheer weight of government-backed mining deals will crowd out the very innovation that would make such deals unnecessary.

All this is not to say that the $3 billion Serra Verde deal, or Project Vault, or the bilateral frameworks, are useless. They are necessary components of a diversified strategy. A country that relies entirely on recycled magnets or iron nitride has not solved its problem; it has merely swapped one dependency for another. Stockpiles provide a buffer against short-term coercion. Allied frameworks reduce the risk that any single partner can be pressured by Beijing. The administration deserves credit for treating the minerals question as a strategic priority rather than a trade footnote.

The risk is that scale becomes a substitute for strategy. The administration has announced more commitments in 18 months than most governments do in a decade. But commitments are not supply chains. A $30 billion figure in a State Department fact sheet does not tell the reader how much will actually reach production, how many projects will fail the transition from pilot to commercial scale, or whether private capital will follow once government money runs out. Critical mineral investment fell by 9% globally in 2025, according to the IEA, even as rhetoric intensified. Battery metals investment dropped by more than 20%. The gap between political language and market reality is widening.

The wiser policy would combine the necessary mining expansion with a much more aggressive push into substitution, recycling and material efficiency. It would treat equity stakes in private firms as an exceptional measure, not a default. It would coordinate with allies not merely on bilateral agreements but on joint R&D, shared standards and co-financed innovation funds, as Japan and Australia already do. And it would accept that total independence from Chinese minerals is neither feasible nor desirable. The aim should be resilience—the ability to withstand coercion without bankrupting the treasury or the private sector in the attempt.

Mr Trump's $3 billion deal makes for a fine press conference. Whether it makes a durable difference depends on what happens next to the other $57 billion that American policy still needs to find.
