Shadow Banking

Shadow banking is a term that came out of the financial crisis of 2007-2009. There is a belief that shadow banking was one of the crisis reasons. Because the excessive expansion of shadow banking endangers the financial stability of countries, this paper examines the impact of shadow banking on financial stability using data from 14 countries of the G20 during 2002-2018. We divided countries into four groups according to the level of shadow banking activity; then, we employed the quantile regression method. The results indicated that shadow banking hurts financial stability (positive impact on financial instability) in countries with a high shadow banking index (fourth group countries). One unit of increase in the shadow banking index increases financial instability in the fourth group countries (high shadow banking) by 1.6 units. But in countries where shadow banking is not very strong (other three groups), shadow banking does not significantly affect financial stability.

Shadow banking comprises a set of non-bank financial intermediaries such as pension funds, investment funds, insurance companies, and other non-bank financial intermediaries that function similarly to traditional banks in terms of performance but are not supervised by the central bank. Given the expansion of shadow banking activities and its impact on real sectors of the economy, this research aims to investigate the effect of shadow banking on the size of government in selected countries (including two groups of developed and developing countries).Methods: This research was conducted using the Panel Vector Autoregression (VAR) model over the period 2002-2022 in selected countries. Results: The results obtained for the group of developed countries indicate that the expansion of shadow banking assets has not led to an increase in the size of government. However, conversely, according to the research findings for the group of developing countries, there is a positive relationship between shadow banking and the size of government. That is, the expansion of shadow banking assets in the group of developing countries has resulted in an increase in the size of government.Conclusions In this study, the impact of shadow banking on the size of government in selected countries has been examined using the Panel VAR model. The results indicate that the expansion of shadow banking assets in developed countries has not led to an increase in the size of government. However, conversely, in developing countries, the expansion of shadow banking assets has led to an increase in the size of government

Monetary policy is one of the most important tools for policymakers to influence macroeconomic variables including production. However, implementing this policy sometimes yields unintended consequences. Understanding monetary policy transmission mechanisms is therefore critical for effective implementation. Research following the 2008-2009 financial crisis indicates that the shadow banking activity can disrupt the monetary policy transmission and weaken its effectiveness. An analysis of Iran’s financial system reveals increasing shadow banking activity. This paper therefore examines how shadow banking affects monetary policy transmission in Iran using a DSGE model that innovatively incorporates the shadow banking sector. We compare two scenarios: a financial system without shadow banking and one including shadow banking. The effects of two contractionary monetary policies—interest rate increase and reductions in money supply growth—on GDP, investment, and inflation were analyzed under each scenario. The findings indicate that shadow banking diminishes monetary policy’s impact on all three variables by weakening the credit channel of monetary policy transmission. In the scenario without shadow banking, In the scenario without shadow banking, all three variables will decline in response to the monetary shock of decreasing money supply growth. However, in the scenario with shadow banking, investment levels are not declining but rising. The impact of monetary policy on output and inflation is diminished in the presence of shadow banking. In the case of interest rate shocks, the results also indicate a negative impact of shadow banking on the effectiveness of monetary policy.
