Capital Regulation after the Crisis: Business as Usual?
AbstractThe paper discusses the reform of capital regulation of banks in the wake of the financial crisis of 2007/2009. Whereas the Basel Committee on Banking Supervision seems to go for marginal changes here and there, the paper calls for a thorough overhaul, moving away from risk calibration and raising capital requirements very substantially. The argument is based on the observation that the current system of risk-calibrated capital requirements, in particular under the model-based approach, played a key role in allowing banks to be undercapitalized prior to the crisis, with strong systemic effects for deleveraging multipliers and for the functioning of interbank markets. The argument is also based on the observation that the current system has no theoretical foundation, its objectives are ill-specified, and its effects have not been thought through, either for the individual bank or for the system as a whole. Objections to substantial increases in capital requirements rest on arguments that run counter to economic logic or are themselves evidence of moral hazard and a need for regulation.
