Highlights

• The U.S. dollar's gradual erosion is compounding America's dangerous dependence on foreign suppliers, especially China, for rare earth elements and critical minerals essential to electric vehicles, defense systems, and renewable energy.
• De-dollarization is accelerating as major economies settle trade in local currencies, while a weaker dollar raises the real cost of imported minerals, squeezing margins across defense procurement and advanced manufacturing.
• China controls over 90% of critical mineral processing and has already weaponized export controls, creating a converging risk where diminished dollar dominance and concentrated supply-chain control expose U.S. strategic vulnerabilities.

The era of the U.S. dollar’s unchallenged global dominance is drawing to a close. Not abruptly, and not catastrophically—but decisively. Its gradual erosion is raising uncomfortable questions not only about monetary power, but about America’s growing exposure across strategically vital supply chains. Nowhere is this more consequential than in rare earth elements and critical minerals, the indispensable inputs behind electric vehicles, advanced electronics, renewable energy systems, and modern weapons platforms.

The United States remains overwhelmingly dependent on foreign suppliers for these materials, particularly China. A weakening dollar layered atop this structural dependency compounds a risk that is economic, industrial, and geopolitical all at once.

Is the Dollar Really Losing Ground?

Yes—but with nuance. The dollar has experienced periodic depreciation against major currencies and hard assets such as gold, reflecting diverging interest-rate trajectories, expanding U.S. fiscal deficits, trade frictions, and long-term debt concerns. While the dollar remains the world’s primary reserve and settlement currency, its exclusivity is diminishing. The issue is not imminent collapse, but structural headwinds to long-term dollar demand.

De-Dollarization Moves From Theory to Practice

De-dollarization is no longer hypothetical. Major economies—including China, Russia, India, and several emerging markets—are settling a growing share of trade in local currencies and developing alternatives to dollar-centric payment systems. A non-trivial portion of global commodity trade, including oil, now clears outside the dollar—a notable shift from near-total dollar dominance in prior decades.

Sanctions, tariffs, and geopolitical fragmentation are accelerating this trend. For countries exposed to U.S. financial pressure, bypassing dollar rails is increasingly viewed as a strategic necessity rather than an ideological choice.

Currency Weakness Meets Supply-Chain Reality

For supply chains, the implications are immediate. A softer dollar erodes U.S. purchasing power, raising the real cost of imported minerals and metals. While this dynamic may ultimately incentivize ex-China and domestic supply-chain development, such transitions take years, not quarters.

For industries dependent on rare earths, lithium, cobalt, graphite, and manganese, currency weakness translates directly into higher input costs, tighter margins, and procurement risk. These are not discretionary consumer goods; they are non-substitutable industrial inputs. Cost inflation reverberates through defense procurement, advanced manufacturing, and in much of the world, clean-energy deployment, and sectors central to national security and economic competitiveness.

China’s Leverage Remains the Chokepoint

That vulnerability is magnified by China’s near-total control over critical mineral processing. By the mid-2020s, China accounted for roughly 60% of global rare earth mining and over 90% of processing and permanent magnet production. This dominance has already been weaponized. Beijing’s export controls—imposed with little warning—demonstrate its capacity to selectively restrict supply, create scarcity, and influence global pricing.

U.S. policymakers acknowledge the stakes. Even a short-term disruption in the supply of key elements such as neodymium or dysprosium could inflict multi-billion-dollar economic damage and impair defense and clean-technology supply chains.

A Converging Risk Profile

The rise of BRICS and other non-aligned producers adds another layer of complexity. Collectively, these countries control a significant share of global critical-mineral reserves and are actively building non-dollar trade infrastructure. While coordination remains uneven, the direction of travel is clear.

As commodities appear to migrate away from exclusive dollar pricing, resource-rich states gain leverage, while dollar-dependent importers lose it—at the margin, but persistently. The convergence appears unmistakable: the prospect of a less dominant dollar and concentrated control of critical minerals reinforcing one another, exposing the United States at precisely the moment these materials matter most.
