The Role of Financial Market Stability on Monetary Policy Transmission Mechanism in Iran: A Multivariate GARCH Approach

The effect of uncertainty on monetary growth in recent years has attracted much attention. The mechanism of monetary transmission through the financial market affects consumption expenditures, investment, and the real sector of the economy. The stock market is an important component of financial markets affected by variables such as investor’s confidence, exchange rate, and money. Uncertainty relationships between variables are investigated by using quarterly data of the Iranian economy during 2001-2018 and the MGARCH-VECH-VAR approach. Increasing real exchange rate fluctuations will lead to increasing investor’s confidence uncertainty and financial market instability, followed by increased monetary growth uncertainty and the real sector of the economy. By increasing the confidence of investors, it is possible to reduce the monetary growth rate, as well as increase consumption through the wealth effect and increase the growth rate of production.
