In the analysis, we explore further with VAR-based variance decomposition and impulse response functions to capture the direct and indirect effects of innovations in one variable and other ones in the same model. The interesting results come out with negative reaction of stock price to credit growth in first 11 months of study period before any reverse trend occurs. And then it will still remain the sign in longer term. However, it seems no significant evidence to prove the positive short-run impact of credit rate on stock price increase. So Interest subsidy policy after global crisis (2008) is not the major reason to rescue equity market. In addition, the variation of key variables including interest rate, inflation and exchange rate has significant impacts on stock volatility in long run. One important policy implication is that authorities should be cautious in implementing monetary policies exposed to inflation risk as it has a consistent adverse influence on stock change in both short and long term. Keywords: Credit growth, Macro-economics, Stock performance and Impulse Response Function. 3 UAN VAN CHAT LUONG download : add luanvanchat@agmail.com CHAPTER 1: INTRODUCTION 1.1 Research context: Ho Chi Minh Stock Exchange (HOSE), formerly HOSTC, is the older of the two stock exchanges in Vietnam. Established on 20 July of 2000, it started operation on 28 July in the same year. The trading system of all stocks listed in HOSE is under the control of State Securities Commission (SSC). HOSE runs as a state-owned one member limited liability company with one-billion VND of chartered capital. At the very beginning, there were only two listed firms, namely REE and SACOM traded two days per week. From 1 March 2002, market traded daily with two order-matching sessions. Till 31 December 2007, 138 stocks were listed and traded five days per week through a fully-computerized trading system, Automatic Order-Matching and Put- Through Trading system. In general, the total capitalization in HOSE accounts for over 40% GOP. During operating time, Vn-Index had a sharp fluctuation peak to 1137 in February of2007 and then turned down sharply, which shocked almost investors and policy authorities. According to some former studies, the root cause is originated from market participant's over-expectation on booming price. Despite HOSE's certain achievements over year, it is still fragile due to its own high risk, big price volatility and poor trading system. As one of Asian emerging markets, HOSE has experienced ups and downs because of the significant influences from external and internal factors. In reality, many controversial problems signal the market inefficiency and instability in terms of information asymmetry, a weak legal framework, the lack of transparency in financial reporting, too much Government intervention in trading transactions and herding investor 4 UAN VAN CHAT LUONG download : add luanvanchat@agmail. Indeed, these weaknesses are the challenges of Vietnam economy towards financial liberalization process. Thus, HOSE in particular or Vietnam stock exchange in general hopefully will develop into a strongly efficient capital-raising channel in the near future. In the development period, the required tasks for policy makers from now on is to do more qualified researches on Vietnam stock market and prevailing problems for timely adjustment. Observing the economic changes since 2002, the rapid domestic credit has grown by nearly 10 times, from about 2 hundred thousand up to more than 2 million billion dong. Simultaneously, stock market boomed aggressively in 2007 when VN Index created history (Figure 1. And the question whether these two factors have any links has raised the interest in further estimation. Then its empirical result below can explain the relationship between domestic credit growth and stock volatility, especially in the period right after the peak in 2007 until the broadening monetary policy in 2009.1: VN-Index & Credit aggregate in 2002Ml-2010M3 5 UAN VAN CHAT LUONG download : add luanvanchat@agmail.com VNINDEX 1,000 800 600 400 200 2002 2003 2004 2005 2006 2007 2008 2009 DOMESTIC CREDIT 2,000,000 1,600,000 1,200,000 800,000 400,000 2002 2003 2004 2005 2006 2007 2008 2009 Sources: IMF (20 10) 6 UAN VAN CHAT LUONG download : add luanvanchat@agmail.com Let's discuss more about Vietnam economic background and why credit growth accelerated the period prior to 2008. A relevant update from World Bank (2007) gave some explanation related to the so-called "Impossible trinity" of simultaneously maintaining nearly fixed foreign exchange, independent monetary policy and an open capital account. Under this implementation, the incident following increasing capital inflows was foreign exchange depreciation or domestic currency appreciation that kept appealing more investors. The economy was put in a challenge of excess liquidity. Due to its negative impact on Vietnam competitiveness of export and growth slow-down, the Government intervened by purchasing foreign exchange and selling securities. Then it moved foreign exchange market much flexibly. However, the foreign reserve accumulation and VND appreciation forced SBV to choose monetary and credit expansion in term of sterilization. This also hid potential exposure to inflation and then unpredictable capital outflows, most seriously a crisis (2008) when the stock value returned its real value. So it raises the interest in finding the real impact of credit growth on stock performance scientifically over the period which will be presented in the following parts.2 The scientific challenge: The research will discover whether credit shocks have significantly affected HOSE performance. Particularly, the credit growth under interest support program in 2009 aimed at economic stimulation after global crisis in 2008. And thesis also generalizes how lagged length between credit growth and stock price reaction would be. Further estimation will uncover which of key macroeconomic and trend variables has remarkably influenced on stock price in both short and long run since 2002. Based on the empirical result, stock investors, academic ! economists and authorities can refer to the findings for their own decision-making. However, 7 UAN VAN CHAT LUONG download : add luanvanchat@agmail.com some existing limitation of data and quantitative tools to interpret it in economic meaning are necessary for further research then.3 Goal and objectives of the research: The overall goal of the project is to provide scientific results as trustworthy references for stock investors. And then it gives some appropriate policy recommendations related to credit applicable for the development of Ho Chi Minh Stock Exchange and Vietnam economy as a whole. To meet the goal, the first specific objective of the research is to identify the cointegration and causality of domestic credit growth to HOSE's performance. Next is to analyze the lag length between the prominent change in some monetary policies and its impact on stock price market over 2002-20 I 0. Especially and specifically, how Decision 131-2009-QD-TTg on Interest Rate Support for Organizations to expand their Production and Business affected stock price will be discussed in the paper. By application of VAR and monetary transmission mechanism (MTM), the research functions forecasting the stock volatility. The second objective is to explain more about interactions among credit growth, other key macroeconomic indicators and HOSE index. The testing will identify how significant and which relationships, negative or positive, each independent macro-variables impact on the dependent stock price. The last is to gtve some recommendation for both stock exchange managers and government policy makers. 8 UAN VAN CHAT LUONG download : add luanvanchat@agmail.4 Research Questions: In order to achieve the above objectives, let's try to answer the following questions: 1. Is there any relationship between credit growth rate and stock price index in long- term as well as short-term? 2. Among potential substitute investment channels via foreign exchange, gold, money and overseas stock markets, does domestic interest rate have the immediate effect on the stock price variation? 3. Associated with credit, are all selective macroeconomic factors necessary for forecasting HOSE price change in the long-run? If yes, what is the sign of individual relationship between stock price and the others? 1.5 Structure of the thesis: The thesis will follow introduction section with four other chapters. Chapter 2 reviews the applicable theories of stock price determination as well as empirical studies about the relationship between security index and macro-economic indicators. Chapter 3 describes research methodology including data collection, variables of interest, econometric model together with empirical procedures. Chapter 4 analyses the research results according to methods recommended previously. It answers the thesis hypotheses whether the causality of Credit growth to stock price change exists, which market the main substitute for stock investment channel is and whether other macro-variables have significant impacts on stock variations. And chapter 5 closes the study with a conclusion, policy implication and opens with its limitation for further studies. 9 UAN VAN CHAT LUONG download : add luanvanchat@agmail.co CHAPTER 2: LITERATURE REVIEW FOR STOCK'S RELATIONS WITH MACRO- ECONOMIC FACTORS This section will provide general concepts and previous valued researches based on which the study can construct. It includes four main parts: key concepts, theoretical review, empirical review and conceptual framework.1 Credit channel Credit channel as suggested by Mishkin (1995) operates through two components - the balance sheet channel and the bank lending one. The concept explains that increasing money supply increases total credit that banks can supply to country economy. And then through the bank financing channel, it will in tum boost aggregate demand and output, eventually push up stock price. In line with the balance sheet channel, Bemanke and Gertler (1995) concerned the external finance premium, which they defined as the bridge between the externally-raised cost of funds and the opportunity cost of internal funds. Yet, this seems not significant in the case of Vietnam because most credit has recently been granted to big state-owned enterprises regardless ofthe consideration of their financial position. Briefly, domestic credit growth via banking loans is the channel the State Bank uses to inject liquidity to the whole market.2 Macro-economics Macroeconomics is the study of the performance, structure and behavior of the entire economy as a whole. It is different from microeconomics which focuses more on individuals and 10 UAN VAN CHAT LUONG download : add luanvanchat@agmail.com how they make economic decisions. Actually, macro-economy is so complicated because there are many factors influence on it. We usually analyze macro-economy by primarily looking at national output (GDP), unemployment and inflation. Besides, there are consumption, interest rate, foreign exchange, international trade and international finance which are modeled to explain economic relationships. The study herein will employ some of the mentioned indicators to see how they affect stock market.3 Stock performance Stock performance is a measure of the returns on shares over a period of time. There are several measures of stock performance and each includes its own characteristics and benefits during an analysis of returns.
