Banking system, as one of the most important parts of macroeconomy, plays a vital role in general economic equilibrium and transition of economic shocks in the society. Because of that, it is of sensitive role in national economy. In addition to implementing dictated monetary policies of central banks, they as any economic business, pursue the goal of increasing their profitability. In this study, we use Dynamic Stochastic General Equilibrium (DSGE) and take into account five economic sectors, namely households, entrepreneurs, mediator banks, distributors and government, to study the reaction of banks to emergence of monetary shocks. For this purpose, the authors seek to make use of long-term macroeconomic parameters. The results of our model show that, upon emergence of a positive shock on interest rate, due to the decrease of request for loan and the amount of lent money, the rate of loaning and as a result, the profit of banks is reduced, and in the case of a positive oil shock, the amount of market liquidity increases so the rate of loaning decreases and the scale of investment increases and finally, the households’ willingness to save is reduced. Therefore, the outcome of decrease of lending rate and decrease of deposits leads to a reduction in banks’ profitability.

Designing a New-Keynesian dynamic stochastic general equilibrium model, in this paper, we evaluate the impacts of monetary shocks originated from monetary base and monetary multiplier on fluctuations of macroeconomic variables in Iranian economy. Due to importance of financial sector in transmition of economic policies effects, banking system and its current status such as fixed asset accumulation and NPLs has been added to the baseline model. Calibration of parameters of model according to quarterly data of Iranian economy during period 1990-2014 shows that the model fits the data quite satisfactorily. We find that a negative shock to reserve requirement results in slight output growth and inflation while a positive shock to banks’ borrowing from central bank results in output decline and higher inflation. In other words, for the same amount of liquidity growth, increasing of liquidity from a change in monetary multiplier, in contrast to change in monetary base, results in lower inflation and stimulating output. Therefore, it has been suggested that monetary authority should control the amount of borrowings made by banks and, instead, decreases their reserve requirement ratio as an incentive tool. This approach will encourage banks to adhere to their credit line limits and avoid overdrafts which result in higher level of stability in macroeconomic variables through monetary discipline.
