Post-crisis challenges to bank regulation

The current crisis has totally transfigured the world's financial landscape. The lessons we have derived have also transformed our perception of banking risks, contagion and its implication for banking regulation. It is now well established that risks were mispriced, accumulated in neuralgic points of the financial system, were amplified by procyclical regulation and the instability and fragility of financial institutions. Yet the implications on the design of post-crisis banking regulation are unclear. In this article we summanze the key issues the new regulatory framework have to consider and how they relate to one another. As the debate over the new financial regulation architecture has evolved, two different views seem to emerge: one views banking cuses as an unavoidable phenomenon, so that regulation should provide a framework to cope with its impact. The other considers that cnsis could be avoided provided banking regulation is duly modified. We argue that for consistency reasons choosing one view or the other hads to a completely different perspective on the future of banking regulation, as it implies a different view on the banking industry, bank stakeholders' rights, banks' corporate governance and contagion. As a consequence, choosing the incorrect view of banking crises may lead to an inefficient banking industry.
