The role of capital adequacy requirements in money creation in the banking system

One of the most important factors affecting the creation of liquidity in Iran's banking network is the capital adequacy ratio. Based on this, the present study aims to investigate the role of capital adequacy requirements on money creation in the banking system based on Bal III committee as well as the effects of other variables such as inflation, exchange rate, non-performing loans, and profitability of the banking network in Iran in the period of 2010:1-2021:1 with seasonal frequency using structural vector autoregression model. The results show that a positive shock to inflation, exchange rate, and profitability of banks increase money creation. But, a positive shock to capital adequacy ratio and non-performing loans has not had a significant effect on money creation. This finding indicates that the banking system has practically not reacted to changes in capital adequacy due to the lack of executive guarantee in applying the capital adequacy requirements. And as a result, capital adequacy requirements have not been able to play their role in restricting money creation. Also, the results show that the creation of bank money in Iran is mainly influenced by macro-level variables so that inflation and exchange rate respectively played the most important role in explaining the changes in the creation of bank money.
