市场风险约束下城市商业银行的最优规模研究

Study on the Optimum Scale of City Commercial Banks under the Market Risk Constraints

在考虑市场风险的情况下,当前城商行的实际规模已经超过了其最优规模。进一步研究表明,利率浮动水平和存贷比例都会对城商行实际规模偏离最优规模的程度产生影响。因此,监管部门应当围绕维护金融稳定和服务实体经济目标,在推进金融改革的过程中应当充分考虑市场风险对城商行的冲击,并通过差别性调控对城商行规模控制进行引导和激励。对资本充足、中小企业贷款占比高的城商行,可放松其利率管制水平和存贷比限制,以通过资本充足率的适度下降换取高收益。对于资本充足率和中小企业贷款占比都比较低的城商行,则坚持利率和存贷比管制,加大其规模收缩的压力。

The actual size of city commercial banks has exceeded their optimal size considering the market risk. Further research shows that, the floating interest rates and the level of loan - to - deposit ratio will have an im- pact on the deviation between real size and the optimal scale. Therefore, regulators should ：locus on the target of financial stability and servicing the real economy, fully consider the impact of the market risk in the process of financial reform, and guide and encourage the city commercial banks to control their size hy differential regula- tion. As for the city commercial banks whose capital are adequacy and well supporting SMES, regulators can re- lax the control of interest rate level and the loan - to - deposit ratio to make them achiew high yield with the capital adequacy ratio moderately.decreased. For the city commercial banks, the regulators should insisted on interest rates and loan - to - deposit ratio control, in order to increase the pressure of size constriction.
