- 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.
- India’s Semiconductor Tooling Cluster Extends Global OEM Supply Chains
Applied Materials’ $5 billion and Lam Research’s ₹10,000 crore India commitments establish a second manufacturing geography for global equipment OEMs. Engineering, qualification, and proprietary materials capture most of the economic rent, while dependence on Chinese-processed inputs remains the primary constraint on supply-chain resilience.
- 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.
