When banks prefer securities holding to lending, bank-dependent borrowers would be rationed in bank loan markets. This paper examines, both theoretically and empirically, the incentive of banks to hold securities rather than loans. When banks are in trouble due to an external shock and subsequent drain of deposit, they cannot reduce their loans quickly because loans are illiquid and are not easy to sell. Therefore, banks should respond to insured deposit drain by raising uninsured CDs or debentures. However, they cannot raise enough money through uninsured CDs or debentures when there is costly external finance premium. Meanwhile, if banks hold securities which are highly liquid, they can sell those securities and thus endure deposit drain without costly external financing. This explains why banks hold liquid securities of which yields to maturity are lower than those of loans. Banks' preference for securities comes from the existence of costly external finance premium, which is inversely related with bank net worth. After all, if bank net worth is kept high enough or capital market incompleteness is not severe, the preference for securities should be weakened.

This paper estimates the optimum level of reserves in Vietnam based on the approach of reserves' cost-benefit and sovereign risk which is one of developing countries' characteristics. The cost of reserves is the opportunity cost when holding reserves. The benefit of reserves is the loss due to country's default in case that there is no reserves to finance external debt payment. The optimum reserves is found out by minimizing the total of opportunity cost and loss due to country's default with the probability of default. Through the usage of HP Filter method for calculating the loss due to country's default, ARDL regression for the risk premium model and lending rate of VND as proxy for opportunity cost together with the Vietnamese economic data in the period of 2005 - 2017, the empirical results show that the optimum reserves in Vietnam is almost higher than the actual reserves during the research period except the point of Q3/2008 and the last point of research period - Q4/2017. Therefore, Vietnam should continue to increase reserves for safety but Vietnam does not need pushing quickly the speed of increasing reserves. In addition, controlling Vietnamese optimum reserves is necessary to help the actual reserves become reasonable.

In this paper, we address how the monetary authority should react to financial market status and exchange rate movements in a small open economy New Keynesian model with financial frictions due to asymmetric information between savers and borrowers. We show that the small economy with financial frictions is more susceptible to the exogenous shocks under the fixed exchange rate regime than under the flexible exchange regime. The small economy experiences a more prolonged and deeper economic recession under the fixed exchange rate regime than under the flexible exchange rate regime. The monetary policy taking into account external finance premium is better than the interest rate rule without considering the financial market status.
