In spite of what the CNBC article says, there has not been, to my knowledge, any denial by PBoC of the Caixin article.  Bobby Lee did not say that (did he?).  If there had been such a denial, it would be in block letters all over the place.  I found no new announcements on the Huobi and OKCoin websites. (Are there any?)

On the contrary, it seems that all major Chinese exchanges except BTC-China have had at least one bank account closed to client deposits, and they remain closed.  However Huobi and OKCoin still have accounts on other banks that (according to the exchanges) have not yet received any orders in this regard.

One of the two banks used by Huobi that did block client deposits has set an April 18 deadline for blocking withdrawals too. So the only part of the Caixin report that was proved wrong, so far, was the date of the final deadline (which Caixin reported as April 15).

The market may be assuming that the bank situation will not get any worse.  If that is the case, all exchanges should be able to function normally.  (As long as they have one bank account open for deposit, the closure of other accounts should not make much difference, should it?)

We'll see.
