using the Generalized Methods of Moments (GMM) approach The estimation results indicate that monetary policy change has negative impact on the supply of bank loan and the magnitude is different among banks Bank characteristics i.e asset size, liquidity, and capitalization depress the negative impact of monetary policy change on the supply of bank loan The purpose of this study is to hope policy maker take into consideration when using monetary policy to regulate the supply of bank loan in the context that different bank react and absorb the monetary transmission differently Key words:

APPENDIX 74 Page CHAPTER 1: INTRODUCTION This chapter begins the thesis research by introducing the research topic and states the research problems in terms of social and scientific point of view This chapter also includes research objective which is what the paper intends to study and states the research questions The next part is research methodology, which presents briefly the method will be used in the paper to solve the research objectives and obtains the answers for research questions The final part of this chapter presents the organization of the thesis 1.1 Problem statement Banking system plays a significant role in economic development process in Vietnam Banks are considered the capital transmission channel of the economy and its activity covers all economic and social activities Banks are financial intermediaries between savers and borrowers It provides capital for the economy and bridges the companies with market Therefore, it will be an effective tool for government to regulate the economy The government manages the macro-economy by implementing monetary policy, fiscal policy, foreign capital control policy, and trade policy Among the above policies, the study focuses on the monetary policy and its effect on banking system Banking system leads the market through credit operations and payments between commercial banks in the system following the government regulation Thereby, the banking system expands the volume of money supply in circulation by supplying credit to sectors in the economy and controls them effectively One of the most important functions of banking system is financial intermediary For the economy, this function has an important role in promoting the economic growth by satisfying capital needs for the continuity of production process and production expansion With this function, the bank makes inactive capital into active capital, stimulates the circulation of the Page capital,and promotes business growth.The supply of bank loan represents for the financial intermediary function of the bank The amount of the supply of bank loan indicates how much money relatively goes into the economy Theoretically, the loan supply of bank is influenced by several factors as capital input cost, monetary policies, economic situations, loan demand, etc Within the boundary of the study, the impact of monetary policy on loan supply will be solely discussed in detail Understanding the mechanism and factors, which determine the loan supply of a bank has important implications for strength and distributional effects of monetary policy Understanding how monetary policy influent the loan supply also strengthens the link between stabilization and regulatory policy from the government and the state bank of Vietnam as well as business decision of bankers B S Bernanke and Blinder (1989)suggested bank intermediation is seen to be especially crucial in a situation of asymmetric information and moral hazard since only bank specializes in monitoring their borrowers Moreover, bonds and bank loans are assumed not perfectly substitute so then many firms would turn into bank dependent Thus, the existence of bank lending channel becomes importance in monetary transmission mechanism In this case, monetary policy affects bank assets and bank liabilities It is not only shift the supply of deposit but also the supply of bank loan The importance thing isthat bank relies on deposit financing and adjustsits loan supply schedules following changes in bank reserves as monetary policy shock In this way, monetary policy shocks change the supply of bank loan.The existence of bank lending channel means that with monetary contraction, banks will cut back their loans supply and weak, undercapitalized bank will responds more than large and well-capitalized banks There are also several empirical studies on the field Kashyap and Stein (1995); Kashyap and Stein (1997) and Kashyap and Stein (2000)analyzed disaggregated data of banks and find that large banks are better able to neutralize monetary shocks than Page 10 Table A.6: The required reserve rate of VND in the year 2010 Required reserve (VND) Decision No
