Well, anyway... it appears to be orderly and not out of control.
It'll be interesting to see what they post here. One assumes they will.
I've had this happen with an American business account. Risk management sends you a letter saying they are shutting down the account in 7 days. There's no disputing it, there's no appeal, it's going to be closed. Risk Management simply decides they don't like something about your transaction history and that's that. I'm not sure it's related to Bitcoins, they're probably leaving very little money in that account (probably a good idea) and just keeping enough to send out ACH withdrawals to traders. But when it's 99% of the money coming in is going right back out and it starts adding up to being millions in/out unless you have a huge chunk of money sitting there to cover any issues, banks are not going to be terribly comfortable.
If it was related to Bitcoin (under a BS excuse of money laundering) the account would be frozen. It doesn't sound like it's frozen, it sounds like the bank is saying we don't want your business GTFO.
