In this paper I shall take the causes, developments and economic consequences of the financial dislocations of the last six months as given and generally understood, having already written extensively on this subject, in a more academic vein in the Journal of International Economics and Economic Policy and in a more popular format in the February, 2008, issue of Prospect. Instead I want to turn to the regulatory implications, and official responses, of this continuing event. Being British, this inevitably focuses primarily on issues pertaining to the UK.
