Abstract In the China interbank market, the transaction behaviors of banks are similar and the interbank borrowing is short of regulation, which may result in a big problem. Considering this problem, the present paper constructs a dynamical bank network model, and then studies the stability of the dynamical bank network system with unconstrained behavior and constrained behavior of the agents based on the method of computational simulation. The results show that unconstrained interbank borrowing behavior will increase the system risk of the bank system. Furthermore, when the bank system becomes unstable due to this unconstrained behavior, it is difficult for the central bank to improve the stability of the bank system by adjusting the money policy of the deposit reserve rate.
