BBC - Peston's Picks: Making banks safe

For what it's worth, there are two reasons why it might make sense to force our biggest and most complex banks to hold more capital than their smaller, simpler peers: if big super-banks have the privilege of knowing that we as taxpayers would always bail them out in a crisis, surely they've got to put in place treble protection against the risk that they'd call on us for such help; also the costs of holding the extra capital might encourage them to slim down and simplify their operations.
