There are numerous aspects concerning financial regulation which the current financial turmoil has high-lighted. These include: (1) the form of deposit insurance; (2) bank solvency regimes, 'prompt corrective action': (3) Central Banks' money market operations; (4) commercial bank liquidity risk management; (5) procyclicality of CARs (and mark-to-market): lack of counter-cyclical instruments; (5) boundaries of regulation, conduits, SIVs and reputational risk; (6) crisis management: (a) within countries, e.g. UK Tripartite Committee; or (b) cross-border, how to allocate the burden of cross-border defaults? This paper describes how the crisis exposed regulatory failings, drawing largely on UK experience, and suggests remedies. (c) 2008 Elsevier B.V. All rights reserved.
