Deposit Competition,Debt Structure And Business Risk Of Commercial Banks

With the cancellation of the floating ceiling of deposit interest rates,commercial banks are facing increasing competition pressure.In order to compete for limited deposit resources,commercial banks are competing to raise deposit rates and adjust debt structure.The change in the debt structure is the result of commercial banks' response to deposit competition,which in turn will have an impact on the operational stability of commercial banks.This paper intends to study the relationship among deposit competition,debt structure and operational risk of commercial banks,to explore whether deposit competition is the influencing factor of the change of debt structure,and how the change of debt structure will affect the operational activities of commercial banks.Firstly,this paper defines the concepts of deposit competition,debt structure and operational risk,and finds that the impact of deposit competition and debt structure on commercial banks' operational risk is uncertain,and the impact mechanism and results are different.Secondly,through collecting the relevant data of listed commercial banks,the paper analyses the deposit competition situation from three aspects: deposit interest rate,number of banks and Lerner index,and analyses the debt structure from the perspective of the overall allocation of bank liabilities,the structure of deposit liabilities,the structure of non-deposit liabilities and the dynamic change of the structure of liabilities.Then,through the establishment of Lerner index to measure deposit competition,defined the debt structure variables,calculated the Z value of bank operational risk,and the fixed effect regression analysis of panel data is carried out with Stata software.The empirical results show that deposit competition is an important factor leading to the change of the debt structure of commercial banks.At this stage,the proportion of active liabilities of commercial banks increases,the scale of interbank liabilities and non-deposit liabilities increases,which increases the operational risk of commercial banks.Deposit competition also increases the operational risk of commercial banks.Finally,this paper puts forward the countermeasures to enrich the means of deposit competition and strengthen the risk management of debt.The innovation of this paper is that it links the deposit competition,debt structure and bank risk,which is a useful supplement to the channel of “deposit competition – asset change – bank risk”.At the same time,the theoretical and empirical analysis of deposit competition and debt structure in this paper also enriches the existing research results.
