Banking law QUESTION:- ‘regulation, or any form of official intervention, is only justified in the presence of a substantial market imperfection, and where the cure is not worse than the original disease’ [Howard Davies ‘Why Regulate? http://www.fsa.gov.uk/Pages/Library/Communication/Speeches/1998/sp19.shtml ] With reference to the above statement, critically evaluate the rationales for banking regulation. How far do such rationales explain the UK post-crisis regulatory response?
