Research On The Impact Of Monetary Policy On The Efficiency Of Commercial Banks

As for the impact of monetary policy on banks,although lots of scholars have made relevant researches in the past,there were relatively few direct researches on the impact of monetary policy on the efficiency of commercial banks,and the vast majority of them were targeted at a certain country or a certain field of research,while the relevant researches on global issues were scarce.The management of commercial banks is closely related to monetary policy.Therefore,the paper has certain research significance to explore the impact of monetary policy on the efficiency of commercial banks from the perspective of global level.Based on the data of global commercial banks,the paper directly explores the influence of monetary policy on the efficiency of commercial banks from the perspective of the global level.Then the bank efficiency,bank risk and monetary policy are analyzed in the same framework to verify the intermediary effect of bank risk.It further explores the differences in the impact of monetary policies on the efficiency of commercial banks in different monetary policy directions,different countries,banks of different sizes and during,before and after the financial crisis.The study finds that from the perspective of the global level,monetary policy easing improved the efficiency of commercial banks,and the intermediary effect is established.Monetary policy can indirectly affect the efficiency of banks by affecting the risk level of banks.The impact of monetary policy on the efficiency of commercial banks is asymmetric.Loose monetary policy has a greater inhibitory effect on bank efficiency than tight monetary policy.The effect of monetary policy on bank efficiency also differs between developed and developing countries.Tight monetary policy in developed countries improves bank efficiency while loose monetary policy in developing countries improves bank efficiency.The heterogeneity analysis of bank size show that monetary policy has a more significant impact on small banks than large banks,and monetary policy easing will improve the efficiency of small banks.The results of exploring the impact of the financial crisis show that the bank's sensitivity to monetary policy is relatively higher after the the financial crisis.
