- The Rare Earth Know-How Embargo
China's controls on rare earth expertise target the operators and engineers required to bring Western separation and magnet plants to commercial yield. Tacit process knowledge is the binding constraint on replication.
- Equity Is the Collateral That Makes Critical-Mineral Offtakes Enforceable
China’s tungsten export controls expose the limits of price-only offtakes. Equity aligns capital with construction risk, secures priority under provenance rules, and adds governance rights that make long-term supply commitments more enforceable.
- Rare Earths: The Real Margin Is Scarcity Insurance
Rare earths are increasingly an insurance market rather than a commodity market. As China's export-control suspension approaches its November 10, 2026 expiry, the highest-margin business is selling supply certainty through price floors, offtake guarantees, and future scarcity derivatives.
- The Critical Minerals Water Bottleneck: Why Hydrology Is the Hard Constraint on U.S. Scale-Up
Water scarcity is the hard physical constraint on U.S. critical minerals scale-up. This analysis maps how hydrological limits in the American Southwest gate the social license to operate for lithium and rare earth mining, and why Direct Lithium Extraction and Zero-Liquid Discharge are the engineering responses, with their energy, reagent, and capital trade-offs.
- The Rare Earth Bottleneck Is Processing, Not Mining
China controls 91% of rare earth refining and 98% of heavy rare earth separation. Western mining is expanding, but separation, magnet manufacturing, and process expertise remain the binding constraints.
- Mapping the Energy Security Transition to Physical Constraints
The energy security transition is not a discretionary narrative; it is a structural regime shift. Mapping localized physical bottlenecks — liquefaction capacity, nuclear regulatory compression, rare earth processing deficits — to conviction-weighted portfolio factor loadings.
- The Thermodynamics of Strategic Decoupling
The semiconductor supply chain is not a policy debate — it is a physical constraint. Advanced packaging, equipment tooling, and rare earth processing cannot be duplicated instantaneously. The irreversible timeline for strategic decoupling is approximately 2028-2032.
