Having put aside the original goal of the BU – cutting the perverse link between sovereigns and banks – the aim of common supervision of our banks should be to keep them well-equipped to fulfil their fundamental task, that is to provide credit to the healthy part of the economy.
A bank crisis, still possible for many reasons, should be addressed in a unified, European way, minimizing the financial involvement of taxpayers and thus moral hazard. What we should avoid as supervisors is losing sight of these final aims in order to pursue a sort of bureaucratic integrity.
