After the financial crisis in 2008, many developed and developing countries have started to use unconventional monetary policy tools to ensure financial stability along with price stability. As of 2011, the Central Bank of the Republic of Turkey (CBRT) has started to use unconventional monetary policy tools to support financial stability. In this study, a financial stability index has been calculated for the Turkish economy and the effects of interest rate corridor and required reserve implementations which used by the CBRT, on this index were examined with the Non-Linear Auto Regressive Distributed Lag (NARDL) model. According to the results of the analysis, it has been understood that the effects of unconventional monetary policy tools in ensuring financial stability are limited and monetary policy implementations alone are insufficient.
