What if a copper shortage stalls grid expansion?
A copper crunch stalling grid expansion is a direct, well-mapped trade: Freeport tracks the metal higher and copper signals as the growth tell. Rhymes with the Sept-2025 Grasberg halt and July-2025 Comex copper record that tightened the complex. Transmission: hits every interconnection and data-center buildout, lifting transmission costs globally; Chile/Peru/DRC supply leverage rises. Forward angle: electrification plus AI load makes copper structurally short — dips are buyable, and the XCU/industrial_demand map is well-calibrated.

What it would mean
If this plays out, it is a mixed shock. A copper supply crunch stalls grid expansion and renewable interconnection, inflating transmission project costs. The trigger decomposes into signed root‑shocks — Copper ▲ · Industrial demand ▲ — which propagate through our causal graph to the markets below.
