Monetary Policy Efficiency in Conditions of Excess Liquidity Withdrawal

In case that a central bank is withdrawing excess liquidity, there arises a question whether the monetary policy based on repo operations (withdrawal repo) is identically efficient as the monetary policy relying on repo rate connected with reverse repo (issuance repo) when central banks provide liquidity. The analysis of this problem is a main subject of the article. Authors develop microeconomic model of commercial bank behaviour, which is used for the definition of conditions when the interest rate policy of central bank based alternatively on repo rates for repo and reverse repo operations is efficient. Statistical data (time series of 1998 - 2011, monthly data frequency) are analysed and econometric verification of alternative forms of econometric models is performed. The authors arrived at a conclusion that the Czech National Bank´s monetary policy operating in conditions of excess liquidity withdrawal through repo operations is efficient. In case of the Czech Republic an increase in repo rate on withdrawal repo should lead to an increase in interest rates of commercial banks and to a reduction in the credit activity of commercial banks and hence to the successful implementation of Czech National Bank´s restrictive monetary policy.
