The interbank rate has a great impact on the bank's economic activities that it is one of the important instrument for central bank policy. Banks to back up their funds or liquidity demand participate in the interbank market. These change their needed or surplus liquidity based on interbank market conditions. According to this, liquidity requirements can change the central banks' monetary policy and it as a policy instrument along with central bank policies in the interbank market can influence the banks' behavioral how to provide or allocate liquidity in this market. This paper focuses on the liquidity requirement of Basel III and surveys the impact of the requirement on central bank policies in the interbank market. We link the structure of the balance sheet of banks and central bank policy. The results show that the liquidity requirement of Basel III (liquidity coverage ratio: LCR) is an appropriate alternative to central bank policy. The ratio of liquidity coverage ratio has a positive and significant relationship with the interbank market rate and the central bank can monitor the interest rate in the interbank through a liquidity coverage ratio.
