Providing a Solution for Managing the Interest Rate of Iranian Bank In the Context of Development and Financial Repression Theorie

In the Iranian economy over the past few decades, the financial system has been subject to many restrictions, including the grading of bank interest rates. In this study, considering the economic conditions of Iran, the interest rate of bank deposit is determined by combining the two approaches of liberalization and financial development and financial constraint. In this way, contrary to the bank's interest rate order, the central bank has issued two interest rates as a ceiling and a bank interest rate to banks, which are upper and lower limits. Banks can then operate freely and competitively, depending on their performance, between profit and loss ceilings, and determine the appropriate rate of interest for the banks themselves and adjust the business cycle more quickly and maintain their finances. To do this, a smooth panel regression model (PSTR) with data from the central bank and commercial banks of the country in the interval (2006-2016) has been estimated high and low.bank deposit interest rates.
