One risk in the present trend to remove supervision from the tasks of central banks is that central banks could be left with a responsibility for overall financial stability that is neither clearly defined nor supported with the necessary powers or access to information to discharge it.
So where separate supervisory authorities are being established, it is important to set up a structure that promotes the necessary exchange of information and permits the central bank to influence the design of prudential rules. Much attention is being given to this subject in the countries where new supervisory structures are being put in place.
