From Resource Endowment to Supply-System Continuity: Brazil’s Rare Earth Downstreaming Paradox

Brazil holds a large rare-earth endowment and, since 2024, a commercial upstream operation, yet geological abundance has not translated into secure access to separated oxides, metals and magnets. This study examines how far Brazilian rare-earth capability extends along the value chain and why. We combine official mineral and trade statistics, facility disclosures, policy documents and peer-reviewed literature to score seven stages annually from 2015 to 2026 against explicit decision rules, distinguishing technological from commercial maturity and measuring how many consecutive stages from extraction operate at each level. Commercial capability now covers mining, beneficiation and the production of a mixed chemical intermediate, while separation, metallisation, magnet manufacture and circular recovery remain at research or pilot level. The record also reveals a discontinuity: pilot separation capacity documented in the mid-2010s was not sustained. Part of the recent downstream progress is disconnected from domestic feed, and the main commercial operation has been integrated into a foreign mine-to-magnet chain. We describe this configuration as a downstreaming paradox. For resource-rich economies, the findings indicate that resilience depends on connecting conversion stages in sequence, selectively and subject to explicit environmental safeguards that should be independently assessed before scale-up, rather than on extraction alone.
