Makes it more difficult to send international wires, but not impossible by any means. Neither bank is prohibiting all of their busienss customers from sending wires, rather only the basic, entry level business checking accounts are no longer permitted. All that is necessary is to upgrade to a premium business account. With chase, their premium business account for $95/month you get 4 or 5 free international wires, that hasn't changed at all.
This is getting blown way out of proportion.
This is the conclusion that I am coming to as well. It seems that they are just jacking up the rates for certain banking features -- i.e. making it more expensive for you to send international wires.
