We used the data of Federal Reserve Bank for the period comprises between the third quarter of 2008 and the final quarter of 2018. First, we applied different statistical tools to analyze the obtained data. We carried out normality test and found that both the time series are non-normally distributed. Then we concluded through unit root test that both series are stationary at the level form. Furthermore, we found a positive weak correlation between the time series and through Granger causal test we found that there is a bidirectional relationship between the quantitative easing and the monetary stability at 5% level of significance.enQuantitative Easing; Monetary Stability ; Unit Root Test ; Correlation ; Granger Causality TestArticle
