Freedom of capital, mostly. Also, there are valid reasons to bank outside your native country. The wealthier you are, the less location matters, and the more reasons you might have to bank "offshore" (or at least outside your native country). An example: a friend who often travels to the UK asked his local bank if he could get a GBP denominated credit card (+ settle it in GBP). Wasn't possible. He opened an account in Jersey (or Guernsey, can't remember), where this wasn't a problem.
