This has been going on for quite a while in the US. A couple of years ago Chase closed thousands of accounts that were receiving cash deposits to avoid some trumped up laundering rackets. They literally destroyed small businesses in the process, some of whom had been banking with them for a long time. BofA and WF have both been known to close accounts of those they suspect of trading BTC. When they do so, the funds are held for two weeks before returned to the owners.
When Chase started doing it, there was an article in one of the major disinformation rags in which they were lauded and it was pointed out that all banks should follow their lead.
