The effects of International financial integration on the fluctuations of variables in response to shocks are a matter of heavily concentrated literature of the business cycle in recent years. In this paper, a New Keynesian DSGE model is developed in which there is a channel for capital account changes through the foreign depositchr('39')s inflow and outflow. Then the effects of financial integration are simulated. The integration factor is defined by the percentage of the total foreign deposits absorbed by the banking system. This coefficient could change due to changes in effective domestic interest rate and global interest rate. This paper shows in presence of oil shocks, the fluctuation of production, consumption, real exchange rate and variables of the banking system such as deposits and loans, is higher in financial integration but there is no significant difference in inflation. In presence of technology shocks, there is no significant difference.
