Financial sanctions have economic consequences for the oil-dependent economies. We examined the impact of financial sanctions on exchange rate fluctuations and macroeconomic variables in Iran. To this end, we employed a new Keynesian DSGE model. The results indicated that with the shock in foreign exchange, production (Y) and imports initially decreased. Oil production has shown a positive reaction initially and a negative reaction in the medium term, and after 7 periods, the effect of the shock has disappeared. The capital stock (K) also decreased initially, and in two periods, it reacted positively. In the tenth period, its effect disappeared, and in the long term, it became partially negative, and its effect disappeared. The inflation rate has decreased initially, and its effect disappeared over time. Consumption decreased, and after five cycles, the reaction became positive and then disappeared. The interest rate increased initially and then decreased, and in the 10th period, the shock effect disappeared. The exchange rate initially decreased and then increased after one period.

Financial sanctions have many economic consequences for the oil exporting economies. The sanctioned economy adopts economic policies to deal with it. This paper examines the relationship between financial sanctions, oil revenues and monetary and fiscal policies in Iran and explicates how financial sanctions have affected Iran's access to oil revenues. It also examines the role of fiscal and monetary policies in financial stability and resilience in Iran's economy. To this end, we employed a DSGE model with the new Keynesian approach. The results indicate that the interest rate, consumption, imports and inflation have a positive reaction to the oil revenue shock resulting from financial sanctions. However, the production, export, private sector investment and oil sales indicate a negative reaction to the oil revenues’ shock. Regarding the monetary policy shock, the reaction of production and consumption to the shock is positive. However, the reaction of oil sales and interest rate to this shock is negative. In terms of financial policy shock, production, consumption, investment and export indicated a positive reaction to this shock. However, the interest rate, imports and oil sales indicated a negative reaction to the fiscal policy shock. Monetary and fiscal policy shocks increase the effect of financial sanctions for a short period, while monetary policy shock has reduced the effect of financial sanctions for three periods. Therefore, monetary policy has been more effective than fiscal policy in reducing the effect of financial sanctions.

A developed financial system, which ensures the provision, allocation, and direction of resources toward productive economic sectors, is one of the key drivers of economic growth and development. On the other hand, given the low efficiency of various economic, productive, and social sectors, attention to total factor productivity (TFP) is fundamental for global competitiveness. Given resource constraints in the economy, improving this factor can enhance investment, optimize resource allocation, prioritize productive sectors, reduce costs, improve product quality, and increase value added in economic sectors. Accordingly, the present study aims to investigate the impact of credit on total factor productivity and the growth of value added in Iran’s economic sectors using the Panel ARDL approach and quarterly time series data from 2012Q1 to 2024Q4 (Persian calendar). The results indicate that real credit, real exchange rates, and real capital formation in machinery have a positive and direct impact on the growth of value added and total factor productivity in economic sectors. Specifically, credit in the industrial sector and exchange rates in the service sector exert the greatest influence on TFP and the growth of value added. Additionally, capital formation in machinery in the agricultural sector has the most significant impact on total factor productivity.
