Abstract
Aim and Introduction
The financial sector has seen considerable growth in many post World War II western economies. The consequences of the Great Financial Crisis of 2007-2009 displayed how large the reach of the industry is, and how actions taken by a few important role players, can harm the general public. It is due to the consequences of the Great Financial Crisis that the notion of reforming the banking sector came about. The call for reform occurred in the 1940s as well, after the Great Crash. It was here that Full Reserve Banking (FRB), the broad term for the proposed banking reform and the subject of this dissertation, originated.
The Great Crash ended a period of expansion and growth in the USA in the 1920s where credit was easily available, and the money supply grew. The subsequent Great Depression was an economic event of unprecedented dimensions (Temin, 2000). The years 1929-1933 held a stock market crash, a banking crisis, and a collapse of commodity prices. Friedman and Schwartz (1963) contended that the primary propagation mechanism of the Depression was the contraction in the US money supply, together with banking panics. There were three banking crises in that short period, and it was the failure of two large banks, the Bank of United States and Caldwell and Company, that caused most of the problem. These banks had undergone rapid credit expansion in the 1920s and collapsed under the pressure of the recession (Temin, 2000: 307). A response to the recession was to say that the root cause was bad banking practice and that stricter regulations should be imposed to prevent future crises. Regulation was introduced in The Glass-Steagall Act (1933) however, a more severe suggestion was that bank deposits should be fully backed by bank reserves, Full Reserve Banking, an approach proposed in the Chicago Plan.
The Chicago Plan was proposed by Henry Simons, Irving Fisher and others, to prevent another crisis. It proposed requiring banks to hold 100 per cent reserves. This would simultaneously curb the possibility of reckless lending, and eliminate the risk of bank runs, thereby eliminating the possibility of another banking crisis.
Over the past years, the nominal capacity of the supply of bank facilities has increased significantly, and the main increase in bank assets has come from the increase in granting facilities. On the liabilities side of the banks' balance sheets, non-governmental sector deposits (due to paying high interest rates to depositors) during the year 2013 to 2022 has increased by 33.6% on average.
Statistical evidence shows that the real sector of the economy has not benefited much from the expansion of the banking network's balance sheet and the allocation of bank resources has not led to economic growth. On the other hand, it can be seen that the liquidity created by the banking system has not been absorbed by the real sector of the economy and its effects have been manifested in nominal variables in the form of price increases or turbulences in the currency market and other assets. The average growth of real GDP (without oil) during the years 2013 to 2022 was about 1.6 percent.
In general, it can be seen that due to the endogenous nature of money, the central bank has not had a significant success in controlling the growth of monetary aggregates through controlling the growth of the monetary base and its components (statistical evidence in recent decades confirms this); So that the credibility of the central bank's monetary policies has been challenged and the economy has been exposed to continuous threats of inflation and monetary and financial instabilities.
Methodology
This study will employ several techniques for gathering data, including a library type, a documentary branch, and the use of databases, such as those of the Central Bank of the Islamic Republic of Iran and the World Bank. Based on the characteristics of the Iranian economy under fractional & full reserve banking, a random dynamic general equilibrium model was developed for the period 1991-2021. Typical econometric methods are also used to evaluate the hypotheses. This has enabled assessing the effects of the exchange rate shock under two scenarios. It should be noted that the models were estimated in the dynare program space under MATLAB software.
Findings
The exchange rate shock has a negative effect on the consumption of the private sector at real prices, probably due to an increase in import prices. This has led to a decrease in the import of goods. Since imports form a part of the consumption for the private sector, therefore, the consumption by this sector decreases by about 0.5 percent. The Exchange rate shock has had a positive effect on the net foreign exchange reserves of the central bank. The growth rate of the monetary base is also affected by the currency shocks. With the increase in the exchange rate, although the central bank first reacts to the inflationary conditions resulting from the currency shocks through the currency reaction function and reduces the base monetary growth rate, but this situation is not very durable and finally the monetary base growth rate will increase by about 0.4 percent.
If these resources enter the banking system, due to the 100 percent reserve, it has led to the crediting of the banks, and as a result, inflation and final costs have decreased. But in fractional reserve banking, banks create money by attracting deposits, which in turn creates money by them. As a result of this jump, inflation and the final cost will increase.
The exchange rate shock also increases inflation because with the increase in the nominal growth rate of the exchange rate, the marginal cost of each import unit increases and finally the country's inflation increases by 0.7 percent.
Discussion and Conclusion
The purpose of this research is to investigate the effects of exchange rate impulse on the macroeconomic variables of Iran's economy in the conditions of partial and full reserve banking. To achieve this goal, a new Keynesian stochastic dynamic general equilibrium model was designed considering fractional and full reserve banking system (FRB). The realities of the Iranian economy are considered, and then the effects of exchange rate shocks under two types of banking are investigated. After determining the input values of the model and estimating the parameters using the seasonal data of Iran's economy during the period of 1991-2022 using the Bayesian estimation method, the results obtained from the simulation of the model variables indicate the validity of the model in describing the fluctuations of the Iranian economy. The results of the model indicate that, as a result of the exchange rate shock, the growth rate of the monetary base and consequently the amount of money is affected. Under full reserve banking, due to the full reserve of deposits, this has led to a lower increase in inflation and final cost. However, in partial reserve banking, due to the less control of the banking system, despite having two tools to control the growth of the monetary base and the nominal exchange rate, it will create higher fluctuations in the inflation rate and other macroeconomic variables. In other words, the study model has been slightly different from the basic model in the face of the currency impulse, both in terms of the amplitude and the length of the fluctuation

Abstract
Introduction
The volume of the external money supply is determined by the policymaker, but the amount of money and liquidity will be influenced by the individual's decision to combine their portfolios and the behavior of banks (through lending channels and balance sheets) in the internal money supply. From this perspective, the initial change in external currency (monetary base) causes changes in the supply and demand of all types of assets (such as external and internal money) and their rate of return, and the behavior of individuals and banks determines the optimal composition of the portfolio of assets of individuals and banks and the new and balanced composition of liquidity volume. . Due to differences in the structure of the economy in different countries, the external currency itself can be created from different origins, the exogenous increase of each component of the central bank's asset column (monetary base) causes a change in the relative supply of that asset and its rate of return. Liquidity changes have different sources and are due to changes in the supply of different assets that make up different components of liquidity resources and since the components of liquidity resources are not of the same kind and originate from different processes can have different effects on the performance of macroeconomic variables. The purpose of this article is to analyze and investigate the mechanism of the effect of the components of liquidity resources on the macroeconomic variables of Iran. Changes in liquidity have different sources and are caused by changes in the supply of different assets that form different components of liquidity
sources and can have different effects on the performance of macroeconomic variables. For this purpose, a macroeconomic model by including the components of liquidity resources including net foreign assets of the central bank, net foreign assets of banks and non-bank credit institutions, net debt of the public sector to the central bank, net debt of the public sector to banks and non-bank credit institutions and Non-governmental sector debt is designed to show the relationships of economic variables in the framework of a dynamic stochastic general equilibrium model provides.
Methodology
The model presented in this research is a small open economy consisting of six sectors of households, firms, foreign sectors, banks and credit institutions, government and central bank within the framework of dynamic stochastic general equilibrium model of new Keynesians with respect to nominal and real frictions. By optimizing the objective functions of each of the above brokers, the result of the obtained economic relations is a system of nonlinear differential equations under rational expectations that are currently not empirically solvable, especially in larger patterns. But we can use approximation technique to calculate the model solution in the approximate range functionally. In this research, the set of equations is linear logarithmic using the Ahlik method (1999). In the next step, the input values of the pattern and calibration of parameters and variables have been done using the Iranian economy data during the period 2000-2020. Then, using the Dynar software, the system of equations based on the Bunchard-Kahn method is solved. The results of the statistical tests and moments indicate that the proposed model is suitable for simulating Iran's economy.
Results and Discussion
In order to evaluate the different effects of liquidity resources on economic variables, the reaction of these variables to liquidity component shocks based on instantaneous reaction functions has been investigated. The findings of the research show that the net assets of the banking system through balance of payments and net debt to the banking system through the channel of the state financial balance, if the source of liquidity is created, increases the variables of production, consumption and investment and causes mild growth or decrease of inflation and exchange rate variables. However, if the source of the liquidity creation of non-governmental debts is from the channel of facilitation, it has a decreasing effect on the variables of production, consumption and investment, and only increases inflation and exchange rate. The two sources of the net assets of the banking system and the net of government liabilities to the banking system, contrary to the source of non-governmental sector debt due to the creation of added value in the economy, have more productive effects and investment and less inflationary effects, hence, macroeconomic stability will bring.
Conclusion
The reaction of macroeconomic variables for the same liquidity growth based on instantaneous reaction functions shows that different components of liquidity sources have different effects on macroeconomic variables. These results carry the policy message that, in addition to liquidity management, attention to the developments in liquidity resources components is also important in the field of monetary policy. Considering that liquidity has increased by about 5% in all five components of liquidity components, the effects and implications of the five components of liquidity creation sources can be examined. Comparative results indicate that for the specific growth of liquidity, the increases caused by the net assets of the banking system and the net of public sector liabilities to the banking system have more productive and investment effects and less inflationary effects, hence macroeconomic stability. Therefore, it is recommended that the monetary transition policy as much as possible prevent the increase in non-governmental sector debt which leads to increased liquidity.
