Critical materials don't cap the build-out
Critical-materials supply (rare-earth magnets, gallium/germanium, grid copper) scales enough not to hard-cap robotics, energy or semis through 2030 — a cost/sovereignty constraint, not a volume cap, except heavy rare earths (Dy/Tb) and grid copper, which sit further upstream.

What would move itthe measures watched
- watchChina rare-earth magnet export volume to US/EU vs 2024 baseline (monthly tons). Recovery to ~2024 run-rate = easing; sustained gap (US never recovered post-truce) = active leverage cap. Watch the Nov-2026 general-license expiry for re-tightening.
- watchWestern NdFeB magnet capacity coming online (tons/yr commissioned). MP Materials (10X +10kt by 2028), e-VAC, Vacuumschmelze. Rising ex-China sintered-magnet output de-risks the cap; slippage past 2028 keeps it binding.
- watchCopper supply-demand balance for grid/electrification (Mt deficit).
- watchMagnet-free / REE-free motor share and magnet recycling rate. REE-free motors ~15% CAGR; EU magnet recycling targeting 25% by 2027 (from <1%). Rising substitution proves the price/sovereignty framing — buildout continues, just differently sourced.
- watchGallium/germanium licensing status and price (vs Dec-2024 ban). Nov-2025 suspension restored standard licensing through 27 Nov 2026. Watch price normalisation and whether suspension is renewed; expiry without renewal re-imposes the semiconductor-feedstock squeeze.
