An Empirical Analysis Of Influence Of Interbank Business On The Risk Of Listed Commercial Banks

In recent years, with the pace of financial reform accelerating, profit of the traditional business of commercial banks that derive from deposit and lending business, is compressed. Well with the Basel protocol of three carried out in China step by step, tighter regulation will also bring great challenges to the profitability of commercial banks. Commercial banks are eager to find a new growth point.Because of high return, low capital consumption, avoiding regulatory restrictions and other advantages, commercial banks pay more attention of interbank business. Interbank business achieved rapid development in recent years. With the rapid expansion of business scale, the potential risk brought to commercial banks is also gradually increasing, namely the commercial banks risk taking level is being smaller. Studying on mechanism and effect degree of interbank business for commercial bank risk taking, has important practical significance to regulate commercial interbank business development.This paper is divided into five parts. The first part is the background and significance of this research, research methods and ideas, then sums up the research results of domestic and foreign scholars on issues related to interbank business and risk taking. The second part analyses the mechanism of commercial banks interbank business for risk taking, basing on the cooperation and competition theory, principal-agent theory and stakeholder theory. The third part summarizes the history and current situation of the development of interbank business, and explores the potential risk to the commercial banks, which is brought by interbank business. In the fourth part, with interbank assets occupancy rate and inter-bank liabilities share as explanatory variables, Z-score as dependent variables which is assumed to represent commercial banks risk indicators, the empirical test on the interbank business risk taking is implemented. The results show that:the interbank assets share is positively correlated with the risk taking. That is to say, the higher the proportion of interbank assets, commercial bank risk taking is higher; the interbank debt share is negatively correlated with the risk taking. That is to say, the higher the proportion of interbank debt, commercial bank risk taking is smaller. The fifth part put forward countermeasures and suggestions to promote the healthy development of interbank business from the macro and micro two aspects, basing on the related theory and the empirical conclusion.
