I feel like the banking industry needs to catch up here: in this day and age with digital fraud being easy and getting easier, they should be able to reverse any transfer internationally.
This will fall apart when we get to cashing out downstream, or buying physical goods that are on-demand manufactured/shipped, or stock market trades, but a large percentage should be recoverable in $large cases and (outside of certain sophisticated patterns) the receiver of the money who spent it should be on the hook for the difference.
30m unrecoverable as yet is just silly.
