The data is divided into four phases, corresponding to two important events, the financial crisis in 2007 and the significant decline of crude prices from the third quarter of 2014. The research methods employed are the threshold cointegration test of Gregory and Hansen (1996), TY procedure for Granger non-causality proposed Toda- Yamamoto (1995) and Error correction model (Granger, 1987). The results show that there exists a long run relationship between crude oil prices and Vietnam stock market in the entire sample; however, there is no cointegration between these variables in all four phases. There is evidence that crude oil prices unidirectionally affect stock prices in the entire sample and in the second and third phase; and the crude oil price variable is an exogenous one. In the last phase attached with the decline of crude oil prices, no evidence in statistic shows that the oil prices do Granger cause to stock prices. It likely proves that volatilities of world crude oil prices can affect negatively or positively to profit outlooks of the listed companies on Vietnam stock market, and there is a balance between benefits and damages in this period. ECM model indicates that oil prices and stock prices have a positive relationship in short term, and the speed of adjustment of stock price to return the equilibrium state after a shock is slow around 0. These findings also have an important policy implication that helps the government intercept the market to reduce the negative effect from the energy shocks in general and oil price shocks in particular. Those are to pay more attention to domestic production and trade revenues to get more stable budget, research the alternative energy and enhance international cooperation in the energy sector. Key words: Oil price, stock market, threshold cointergration. LUAN VAN CHAT LUONG download : add luanvanchat@agmail. Introduction The oil crude prices has fallen less than $50 per barrel, about 50% of August 2015. The main reason is the oil supply more than demand (see the figure 1). Growing oil inventories and supply typically put downward pressure on near-term prices. The United States discovered and applied the new oil drill technology, called “shale oil revolution”. This pushes the oil production is near 10 million barrels per day. So that it can be offset the substantial oil supply disruption in the Organization of the Petroleum Exporting Countries (OPEC). However, the resumption of significant Libyan oil production, combined with the weakening outlook for global oil demand, the large economies in the word such as China, Russia, Europe area show not good performances about industrial production and expectation for economic growth.1 Global crude oil and petroleum liquids consumption, supply and inventory in 2014 and 2015 (Source: Energy Information Administration). On July 14, the P5+1 (the five permanent members of the United Nations Security Council and Germany) and Iran announced an agreement that could result in relief from United States and European Union nuclear-related sanctions (which include some oil-related sanctions). If the agreement is implemented and sanctions relief occurs, it will put additional Iranian oil supplies on a global market that has already LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com 3 seen oil inventories raise significantly over the past year. All things have put downward pressure on oil prices. Vietnam is net exporter of crude oil, but is a net importer of oil products, the volatilities in crude oil prices or costs of raw materials should affect to revenue resource of state budget and economic growth. Volatilities of world crude oil price can affect negatively or positively to profit outlooks of the listed companies on Vietnam stock market. The companies have inputs from the oil waste products (such as PLV-Petrolimex Petrochemical Corporation, BMP - Binh Minh Plastic Joint Stock Company,.) and other companies have input coming directly from the petroleum sector (PVT- PetroVietnam Transportation Corporation, PVS - PetroVietnam Technical Services Corporation, PVC - Drilling Mud Joint Stock Corporation, GAS - PetroVietnam Gas Corporation) are likely to be impacted negative by the decrease of oil price.2 shows that revenues and productions from 2009 -2015. The crude oil prices have decreased since third quarter in 2014, strongly affecting to crude oil revenues in 2015 although the export productions is bigger than the same period. We are the one of emerging country and its economy depends very large in export activities. The decline of crude oil price will impact to budget revenues and deficit Energy, in particular crude oil has played an important role in our economy. The purpose of this study is to investigate the relationship between crude oil price and Vietnam stock market. In this paper, I will answer this question from several perspectives: (i) Does it exist a long-run relationship between crude oil prices, stock prices and exchanges rates in entire sample? (ii) Do the big world events such as the financial crisis in 2007 and the technology shock called “shale oil revolution” affect to the co-movement of the three? LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com 4 (iii) Can the prior values of crude oil prices predict the future values of stock prices or crude oil prices do Granger cause to stock prices? (iv) Can the exchange rates do Granger cause to stock prices? (v) Is the crude oil price an exogenous variable? (vi) How does the impact of crude oil prices, exchanges rates on stock prices? And How adjusted speed of stock prices to return the equilibrium if having a shock in present? 9. Crude oil export value F2b. Crude oil export production (unit: 1billion dollars) (unit: $1billion ton) Figure 1.2 Crude oil export revenues and productions from 2009 to 08 months of 2015 (source: General Statistics Office of Vietnam). The study will provide investors the market outlook in the future before the oil price fluctuations in the present. Therefrom the investor can make the appropriate hedging strategies and diversification. Specially, for a country which the foreign currency primarily comes from exporting natural resources such as coals, oil …like us, then the strong oil price volatilities will snappily impact its international balances, budget deficits and economic growth rates. Through this study, I hope to provide further evidences about the energy importance to the economy and suggest solutions that government can intercept to reduce marker volatilities LUAN VAN CHAT LUONG download : add luanvanchat@agmail.com 5 The study uses the daily data with the period spanning from 01/03/2006 to 08/31/2015. Year 2006 chosen is the beginning study year, because Vietnam stock market has just had steps on obvious development in numbers of listed companies and trading volume, and can reflect partly economic situation. The entire samples is divided into 04 phases, the first phase from 01/03/2006 to 12/28/2007 , the second phase from 01/02/2008 to 12/31/2009, the third phase from 01/04/2010 to 06/30/2014 and the last phase from 07/01/2014 to 08/31/2015, attaching with the significant decline in oil prices since the beginning of July 2014 due to excessive oil supply while the world economy is still gloomy and has not yet recovered. Threshold cointegration test of Gregory and Hansen (1996) is employed test the long-term relationship of oil prices, exchange rates and stock prices. From the result’s GH test indicate there exists the long run nexus between these variables. Interesting however, the null hypothesis of no co integration cannot reject at significant level 5% in all four phases. This does prove that events in the research stage impact the long-term structure of oil prices and the stock market. The interruptions make them impossible to reach the equilibrium in the limited time of subsample.
