My wife is a yacht broker in Europe. Every large payment from a buyer in EU to a seller in US is a nightmare recently. Correspondent banks just freeze the amounts ($0.5m or more) "to check for AML/sanctions evasion". I believe they just patch their balance sheets and earn interest, not even responding back to the sender until investigated. It takes weeks to get the necessary information to them via the sender's bank, because the whole system is crazily inefficient. They hire the dumbest employees in payments departments. I hope the rich guys will get fed up with this bullshit soon and start using Bitcoin.
