The interplay between liquidity regulation, monetary policy implementation and financial stability

I outline a simple framework for thinking through how the Basel III liquidity regulations - in particular, the Liquidity Coverage Ratio (LCR) - will impact short-term interest rates and the process of monetary policy implementation. This framework suggests that a regulatory premium may arise in some market interest rates, creating a new wedge in the monetary transmission mechanism. I discuss ways in which a central bank could react to this new wedge, highlighting what may be a fundamental tension between implementing monetary policy effectively and using liquidity regulation to promote financial stability.
