Don't worry about it. He won't have any trouble finding banks to move his business to. And money market accounts aren't exactly big-time banking. He can move that cash anywhere. And most, if not all of these institutions will be happy to quietly start doing business with him again after the fuss dies down. I suspect the senior management of all these banks would be perfectly happy to keep right on doing business with him now, but they're afraid of getting their offices and branches vandalized, and their families threatened or actually harmed.
