Research On The Impact Of Leverage On The Credit Business Of Commercial Banks

The outbreak of the financial crisis in 2008 brought great impact to the world financial system,and the banking industry suffered huge losses.In this crisis,the effectiveness and shortcomings of financial system supervision have caused widespread concern,and regulators are beginning to realize the regulatory loopholes in the capital adequacy index.In 2010,the Basel Committee promulgated Basel ?,introducing leveraged regulatory indicators as an important supplement to the regulatory indicators of capital adequacy.It requires commercial banks to have a leverage ratio of at least 3%and a total capital adequacy requirement.It reached 8%by 2016.In 2011,China Banking Regulatory Commission promulgated the "Guiding Opinions on the Implementation of New Supervisory Standards in China's Banking Industry",which stipulates that the calculation method of leverage ratio is the ratio of Tier 1 capital to the balance of assets inside and outside the table after adjustment,and the ratio shall not be less than 4%.A series of domestic and international regulatory policies fully reflect the new trend of micro-prudential and macro-prudential,not only the capital quantity but also the capital quality,and whether the credit business of commercial banks will change under such new trends.What kind of change is worth researching.From this perspective,studying the impact of leverage on commercial bank credit business has great practical significance for commercial banks and regulators.In the theoretical part,the paper discusses the impact mechanism of leverage on the scale,growth rate and structure of commerc:ial banks in China,and further considers the impact of the combination of internal governance factors and external leverage on credit business.In the third chapter,the status quo of China's commercial bank credit business and the status quo of leverage ratio are described in detail.In the empirical part,the panel data of 16 listed commercial banks are selected for 2007-2017,and the following main conclusions are drawn:1)The leverage rate has no inhibitory effect on the expansion of credit scale of commercial banks.The capital adequacy ratio has a significant inhibitory effect on the expansion of credit scale,and the restraining effect on shareholding system and city commercial banks is greater than that of state-owned commercial banks;(2)leverage The rate has a significant inhibitory effect on the credit growth rate of commercial banks,and the restraining effect on the shareholding system and the city commercial banks is greater than that of the state-owned commercial banks.The capital adequacy ratio has not inhibited;(3)the leverage ratio on the credit loans of commercial banks in China Compared with no inhibition,the capital adequacy ratio has not been inhibited,and neither of them has played a positive role in controlling risks;(4)Leverage rate has a restraining effect on the personal loans of state-owned commercial banks,and to joint-stock banks and city commercial banks.There is no inhibition,capital adequacy ratio has a restraining effect on the proportion of personal loans;(5)the largest shareholder's shareholding ratio and the shareholding ratio of the second largest shareholder have a significant impact on the credit scale of commercial banks.The interaction between the size of the board of directors and the leverage ratio has a significant inhibitory effect on the credit scale;(6)the shareholding ratio of the first largest shareholder to the credit loan proportion has a significant impact.The second largest shareholder shareholding ratio and leverage ratio interactions have a restraining effect on the proportion of credit loans.The interaction between the size of the board of directors and the leverage ratio also has a significant inhibitory effect on the proportion of credit loans.The innovations of this paper:(1)At present,most scholars at home and abroad study the impact of capital supervision on credit behavior,from the perspective of capital adequacy ratio,and rarely consider from the perspective of leverage regulation,and this paper clearly derives from the leverage ratio.From the perspective of exploring its impact on commercial bank credit,this paper enriches the literature on the relationship between capital regulation and commercial bank credit behavior.In addition,when discussing the leverage ratio as an important supplement to the capital adequacy ratio,the relationship between the two is systematically explained from the perspectives of theoretical analysis and mathematical analysis,so that the logic of the article is more rigorous.(2)Based on the study of the impact of leverage on commercial bank credit,this paper introduces the internal governance factors of commercial banks,and forms an interaction with leverage to analyze the impact on commercial bank credit.Scholars at home and abroad rarely combine capital supervision,internal governance and bank credit for systematic research.The research perspective is limited to the regulatory indicators of capital adequacy ratio.At present,no combination of leverage,internal governance and bank credit has been found.From this perspective,this paper further deepens the research on bank credit business and makes the article more complete.
