That doesn't make sense. Both deposit and borrowing opportunities exist at some price. Low risk deposits can be sold at a low price and high risk loans can be bought at a high price. If anything, what a bank naturally would want to do is to sell low risk local deposits, taking the cash to buy high risk loans elsewhere in order to collect the risk premium. The same happens in reverse. There is no inherent reason for money to move net-net, unless there is unequal demand for deposits and borrowing. For a place like Samoa, they probably need more borrowing, so banks wouldn't be extracting any cash, but rather bringing it in.
