On the liquidity coverage ratio and monetary policy implementation

Basel III introduces the first global framework for bank liquidity regulation. As monetary policy typically involves targeting the interest rate on interbank loans of the most liquid asset – central bank reserves – it is important to understand how this new requirement will impact the efficacy of current operational frameworks. We extend a standard model of monetary policy implementation in a corridor system to include the new liquidity regulation. Based on this model, we find that the regulation does not impair central banks’ ability to implement monetary policy, but operational frameworks may need to adjust.
