Most central banks now implement monetary policy by trying to hit a target overnight interest rate using one of two types of frameworks. The first involves arrangements for depository institutions to hold a minimum account balance over a multi-day averaging period. The second uses the central bank's lending rate as a ceiling and its deposit rate as a floor for overnight interest rates. Either averaging or a rate corridor can help a central bank hit a target interest rate, but each framework can also have weaknesses in achieving that goal and, in some cases, other associated drawbacks. This paper discusses an alternative possible policy implementation regime, involving a specially designed facility for the payment of interest on a daily basis on balances held at the central bank. This new type of regime could potentially allow smooth monetary policy implementation without the problems associated with averaging or a rate corridor.
