Abstract

This paper examines the roles of bank capital regulation and monetary policy in mitigating procyclicality and promoting macroeconomic and financial stability. The analysis is based on a dynamic stochastic model with imperfect credit markets. Macroeconomic stability is defined in terms of a weighted average of inflation and output gap volatility, whereas financial stability is defined in terms of three alternative indicators (real house prices, the credit-to-GDP ratio, and the loan spread), both individually and in combination. Numerical experiments associated with a housing demand shock show that in a number of cases, even if monetary policy can react strongly to inflation deviations from target, combining a credit-augmented interest rate rule and a Basel III-type countercyclical capital regulatory rule may be optimal for promoting overall economic stability. The greater the degree of policy interest rate smoothing, and the stronger the policymaker�s concern with financial stability, the larger is the sensitivity of the regulatory rule to credit growth gaps.
