A what‑if from the future

What if Andean mine shutdowns triggered a copper supply shock?

Chilean/Peruvian mine halts are a clean copper supply shock: Freeport tracks the metal one-for-one and 'Dr. Copper' spiking reads as a growth/inflation tell that lifts EM FX and export-levered Korea even as it tightens physical balances. Live analogue is the Sep-2025 Grasberg mud-rush and the Jul-2025 50% copper-tariff Comex record, both of which gapped copper. Forward angle: a supply-driven spike (vs. demand-led) is stagflationary, not growth-positive — so the bullish global-growth read is suspect; favor the miner over the cyclical basket.

What it would mean

If this plays out, it is a mixed shock. Chilean/Peruvian mine halts trigger a copper supply shock (Dr. Copper spikes). The trigger decomposes into signed root‑shocks — Copper ▲ — which propagate through our causal graph to the markets below.
