China’s 2026 rare earth export curb hits Japan’s magnets supply chain, Daiwa flags 1.3% GDP risk

AI Market Summary
China's 2026 export ban on rare earths and permanent magnets to Japan, plus the blacklisting of 80 firms, highlights acute midstream chokepoints in separation and magnet manufacturing where Japan remains highly dependent on China. Reported shipment stalls and an estimated 1.3% GDP drag signal near-term supply-chain stress for autos, electronics, and defense-linked manufacturing, raising risk premia across critical-minerals and industrial metals exposures.

China imposed an export ban on dual-use materials such as rare earths and permanent magnets to Japan from January 2026, and expanded the measures in June by blacklisting or watchlisting 80 Japanese companies. The controls have effectively disrupted Japan’s critical-minerals supply chain, with shipments stalling under the new rules, according to estimates by the Daiwa Institute. Daiwa’s analysis indicates a year-long disruption could cut Japan’s real GDP by 1.3%, or about 7 trillion yen. The episode underscores that while Japan diversified upstream supplies, it remains heavily dependent on China for midstream separation and magnet production.
