Control over rare earth production has become a geopolitical lever.
Beneath the soils of Minas Gerais, Goiás, and the Amazon lies nearly a quarter of the world's known rare earth reserves — materials that quietly animate electric motors, wind turbines, military systems, and artificial intelligence. Brazil has long held this geological inheritance without the industrial means to transform it into power. Now, as geopolitical rivalry over critical minerals intensifies and new legislation takes shape in Brasília, the country is attempting to convert geological fortune into strategic agency.
- Brazil sits on 21 million tons of rare earth reserves yet produced only 20 tons in 2024 — a gap that has become untenable as global demand for these materials accelerates across clean energy, defense, and AI.
- China's grip on 90% of global refining and magnet production has alarmed industrialized nations, turning rare earth supply chains into a front line of geopolitical competition — and suddenly making Brazil's reserves a coveted asset.
- The Chamber of Deputies passed Bill 2.780/2026 in May 2026, creating a National Policy on Critical and Strategic Minerals with fiscal incentives, environmental safeguards, and a new governance council — but the Senate must still act.
- President Lula is courting international investors from any nation willing to operate under Brazilian law, a calculated gamble that foreign capital and expertise can fill the industrial void Brazil cannot yet bridge alone.
- The decisive obstacle is not extraction but refinement — the chemically complex, capital-intensive process of separating individual elements that only a handful of nations have mastered — and Brazil has not yet closed that gap.
Brazil holds roughly 23 percent of the world's known rare earth reserves, some 21 million tons spread across Minas Gerais, Goiás, Amazonas, Bahia, and Sergipe. Yet in 2024, the country produced just 20 tons while the global market delivered 390,000. That chasm between geological wealth and industrial capacity has grown impossible to ignore as the world's major powers race to secure materials that have become foundational to electric vehicles, renewable energy, military systems, and artificial intelligence.
The 17 elements in question — among them neodymium, praseodymium, and yttrium — are misnamed. They are neither rare nor earth in any intuitive sense, but metallic compounds whose scarcity is a function of processing difficulty, not geological absence. Refining them demands sophisticated chemistry and infrastructure that only a handful of nations have mastered. China has mastered it most thoroughly, controlling roughly 90 percent of global magnet production and dominating the separation and refinement stages that convert raw ore into usable form. That concentration has alarmed governments from Washington to Canberra, and it has elevated Brazil — the world's second-largest reserve holder — into a competition it was not previously equipped to enter.
In early May 2026, Brazil's Chamber of Deputies approved Bill 2.780/2026, establishing a National Policy on Critical and Strategic Minerals. The legislation creates governance structures to guide research, extraction, processing, and industrialization; offers fiscal incentives to sector investors; mandates environmental certification and traceability; and establishes a Mineral Activity Guarantee Fund to support new credit operations. Companies operating under the framework will be required to reinvest a share of revenue into research and innovation. The bill now awaits Senate consideration.
President Lula has signaled openness to investment from any country — including both China and the United States — on the condition that participants respect Brazilian sovereignty over these resources and comply with domestic law. It is a deliberate posture: Brazil lacks the technical scale to develop these reserves alone, but it holds the raw material and the political will to set the terms of engagement.
The harder problem remains refinement. Extracting ore is achievable; separating chemically near-identical elements into pure, usable form is where expertise and capital converge — and where Brazil's industrial capacity still falls short. Whether the Senate preserves the bill's ambitions, and whether international investors trust Brazil's framework enough to commit, will determine whether the country can translate its underground wealth into a genuine role in shaping the global technology supply chain.
Brazil sits on a fortune it cannot yet fully claim. The country holds roughly 23 percent of the world's known reserves of rare earth elements—about 21 million tons of material scattered across Minas Gerais, Goiás, Amazonas, Bahia, and Sergipe. Yet in 2024, Brazil produced only 20 tons of these elements while the global market churned out 390,000 tons. The gap between what the earth holds and what Brazilian industry can actually deliver has become impossible to ignore, especially as the world's major powers scramble to secure supplies of materials that have quietly become essential to nearly everything that runs on electricity.
These elements—17 of them, including neodymium, praseodymium, and yttrium—carry a misleading name. They are not rare in the geological sense, and they are not earth. They are metallic compounds found in the subsurface, often as byproducts of other mining operations. What makes them scarce is not their existence but the ability to extract and purify them. The refining process is chemically complex and expensive, requiring sophisticated industrial infrastructure that only a handful of nations have mastered. Neodymium, when combined with iron and boron, becomes a high-performance magnet essential to electric vehicle motors, wind turbines, smartphone speakers, and the cooling systems that keep data centers running. These same elements power military satellites, missiles, and drones. Control over rare earth production has become a geopolitical lever.
China understands this better than anyone. It holds the world's largest reserves and dominates the industrial stages that matter most—the separation and refinement of raw material into usable form. China manufactures roughly 90 percent of the world's rare earth magnets. This concentration of power in a single country has alarmed industrialized nations for years. The United States, Canada, Russia, Australia, and South Africa have all identified rare earth production as a strategic priority. Brazil's position as the second-largest holder of reserves has suddenly made it a player in a competition that touches everything from consumer electronics to military capability to the energy transition itself.
The Brazilian government has begun to move. In early May 2026, the Chamber of Deputies approved Bill 2.780/2026, authored by Zé Silva of the União party and reported by Arnaldo Jardim of the Cidadania party. The legislation establishes a National Policy on Critical and Strategic Minerals, creating a governance framework designed to stimulate research, extraction, processing, and industrialization of rare earth elements within Brazil's borders. The bill now moves to the Senate. It offers fiscal and financial incentives to companies in the sector, establishes environmental certification and traceability mechanisms, and creates a council to designate which substances qualify as critical or strategic. A Mineral Activity Guarantee Fund will serve as collateral for credit operations aimed at new investors. Companies operating in the sector will be required to invest a portion of revenue into research, development, and innovation.
President Lula has adopted a multilateral approach to attracting the capital and expertise needed to build this capacity. In speeches and meetings with other heads of state, he has signaled that companies from any country—China, the United States, or anywhere else—are welcome to participate in Brazilian rare earth production, provided they recognize that these resources belong to the Brazilian state and commit to following local laws and policies. This is a calculated opening: Brazil lacks the technical knowledge and industrial scale to develop these resources alone, but it possesses the raw material and the political will to set terms.
The real challenge lies not in finding the elements but in processing them. Mining the ore is one thing; separating individual elements from a mixture of materials with nearly identical chemical properties is another. It requires equipment, expertise, and capital that Brazil has not yet assembled at scale. The country's largest deposits sit in states with existing mining infrastructure, but the leap from extraction to refinement—the step that actually creates value—remains a gap. This is where China's dominance becomes clear. It is not that rare earth elements are scarce; it is that the ability to turn them into something useful is concentrated in very few hands.
What happens next depends on whether the Senate preserves the Chamber's version of the bill and whether international investors believe Brazil can deliver on its promises. The geopolitical stakes are high. Every electric vehicle manufactured, every wind turbine installed, every artificial intelligence system trained requires rare earth elements. The country that controls their supply shapes the future of technology itself. Brazil is betting that its reserves, combined with new policy frameworks and international capital, can break China's grip on processing capacity. Whether that bet pays off will determine not just Brazil's economic future but the structure of global technology supply chains for decades to come.

The Hearth Conversation Another angle on the story
Why does Brazil suddenly matter in this race? It's not like the country invented rare earth technology.
Brazil matters because it sits on a quarter of the world's known reserves. But reserves alone don't mean much if you can't actually process them. China proved that decades ago—it's not the biggest holder, but it controls 90 percent of the refining. Brazil has the raw material; what it needs is the industrial capacity to turn ore into something useful.
So the new law is basically saying, "Come invest here, we'll give you tax breaks and guarantees"?
That's part of it, but it's more strategic than that. The law creates a governance structure—a council that decides what counts as critical, environmental certification requirements, traceability. Lula is saying to the world: you can come here, but on our terms. We own this resource. You follow our rules.
And companies will actually do that? Invest in a new country when China already has the whole supply chain figured out?
They might, because China is becoming a geopolitical risk. The U.S., Europe, they're all nervous about depending on one country for materials essential to electric vehicles and AI infrastructure. Brazil offers an alternative source, and it's offering it now, before someone else does.
What's the actual bottleneck? Is it just money?
It's more than money. It's technical knowledge. Separating rare earth elements from each other requires sophisticated chemistry and equipment. That's where the real value is created, and that's what only a few countries have figured out. Brazil has the ore. It needs the expertise.
So if this works, what changes?
If it works, Brazil becomes a genuine alternative to China in the rare earth supply chain. That means more leverage in global negotiations, more revenue, more jobs. But it also means Brazil becomes entangled in geopolitical competition between the U.S. and China. There's no neutral position in this game.
