systemic crisis management and the impact on monetary policy. the involvement of central banks. an empirical analysis

In a systemic crisis, many institutions in the financial system may face a lack of liquidity and central banks, as lenders of last resort, have to support them in order to ensure their financial stability. The question is: To what extent the involvement of central banks in systemic crises management, by providing liquidity to credit institutions, affects their ability to accomplish the central goal of monetary policy - price stability?To answer this question, through this study, we conducted an empiricalanalysis on the effect which central banks’ involvement in systemic crises management, through liquidity support, has on monetary policy objectives, mainly on price stability. Using a principal components analysis, we built a Monetary policy index and we developed a regression model between this index and the liquidity support provided by central banks in systemic crises.The conclusion we reached is that the provision of liquidity by the central bank to banking institutions in the system affects its monetary policy objectives only on the short -term. Specifically, providing liquidity support leads to an increase in both monetary aggregates and consumer price index in the first two years of the crisis, after which there is a significant dilution of this impact.
