REEx Structural Rare Earth Market Signal Tracker: September 7-12, 2026

Highlights

• USA Rare Earth began physical construction of an ~$1.2B, 800,000-sq-ft South Carolina metals-and-magnet complex targeting 6,400 tonnes/year of sintered NdFeB magnets by 2028.
• REEx Structural Momentum Index rose slightly to 5.1/10, reflecting incremental processing gains but unchanged financing momentum and persistently high Chinese strategic pressure.
• China still controls ~90% of refined magnet rare-earth output and 90%+ of sintered permanent-magnet production, with heavy rare earths Dy, Tb, Y, Sm, and Gd remaining most vulnerable.
• Three forward catalysts dominate the watchlist: the Sept 24 U.S.–China summit, the Nov 10 export-control clock, and the Jan 1, 2027 DFARS compliance deadline.
• Solvay's La Rochelle separation facility discussions with One Investment Management offer a potentially strategic European midstream signal, but no financing has closed yet.
