ABSTRACT

We develop an analytical model to address the question of optimal deposit insurance policy and to examine the impact of deregulation on depositors' welfare and the soundness of the insurance system. We find that the optimal level of regulation depends critically on the functional relationship between risk and return. We show that in general deregulation of bank activities and/or of deposit rate ceilings will in volve tradeoff between depositors' welfare and the soundness of the insurance system. Our analysis also indicates that risk-sensitive premium and capital requirement schedules may not be efficient in managing the risk of banks.
