Analyzing the Impact of Credit Creation in Fractional Reserve Banking on Macroeconomic Variables in Iran

Optimal performance of any economic system depends on the existence of both efficient real and monetary sectors. Financial-monetary system in conventional economics leads to inflation, inefficiency, instability and economic crisis because it is based on credit creation and creating debt. Therefore, designing of ideal monetary system based on Islamic principles requires analysis of dominant monetary system in conventional economics, which allows the possibility of overcoming the monetary system based on foundations of capitalist principles, and its formation on the basis of Islamic principles. In conventional monetary system, banking based on the principle of fractional reserve according to the maturity differences between deposits and lending creates money from Ex-nihilo. In this study, based on Sidrauski's model (1967) the impact of credit creation in the fractional reserve system on macroeconomic variables compared with %100 reserve system. Then, by solving the model, the empirical analysis and calibration will be discussed in the steady state. Theoretical and experimental results indicate that fractional reserve banking by adjusted golden rule of capital accumulation, reduces the accumulation of capital per capita, per capita GDP, per capita consumption and per capita real money balances in the steady state.
