Regulation and supervision of financial institutions is fast moving to a state of things where you might possibly beat the system but not the house. It does not necessarily go to say that the Bank will be regulating for zero failures. Such an approach would of course stifle financial innovation. Human nature.
This would undermine the credibility of monetary policy and the predictability of a systematic policy response in order to preserve price stability. Such a policy would ultimately undermine financial stability and financial efficiency.
