    Abstract

    This paper investigates regulations for banks that covered by deposit insurance in a dynamic setting where bankruptcy entails social costs. Regulatory policy operates through rules governing the bank's capital structure and asset allocation that may be adjusted each period. Throughout, the regulator must take into account that the bank is better informed about the inherent risks of its assets (adverse selection) and may forgo unobservable and costly actions to improve asset quality (moral hazard). Under the optimal regulatory policy under banks face risk-adjusted capital requirements but also hard-caps on size and leverage. In addition, the optimal policy counteracts pro-cyclical bank behaviour through the use of capital buffers.
