The mechanism of effect of economic factors on the volume of bank deposits in Iran's banking system (The test of money endogeneity versus money externality)

The purpose of the present study is to investigate the mechanism of the effect of economic factors on the volume of bank deposits in the banking system of Iran. For this purpose, firstly, the test of endogeneity versus exogenity of money was tested by examining the two views of conformists and structuralists, and then the effect of economic factors on the volume of bank deposits in the banking system of Iran with the threshold approach (STAR) and based on the quarterly data of 1379- 1397 was estimated. The results of the system generalized torques model show the confirmation of the conformist and structuralist views for Iran's economy, but the degree of money endogeneity in Iran is not complete, so the role of the central bank is important both through the monetary base and the increasing coefficient on the money supply. Also, the estimation of the results of the model (STAR) shows; The variables of exchange rate fluctuations and inflation rate, global financial crises have a negative effect and the variables of oil price, liquidity, bank deposit interest rate and bank facilities have a positive effect on the total volume of bank deposits. According to the results; One of the challenges that exists in the banking network of Iran is the government management of banks, therefore, monetary policies are a source of financing and a source of rent, so it is suggested to increase the liquidity of banks and direct it to the real sector of the economy, laws to reduce interference Government in private and public banks, to improve the competitive and banking atmosphere of the country.
