quantify the effect of credit growth ng on credit quality for the commercial banks in Dong Nai In relation to this possible hi ep effect, theoretical framework of the so–called “three shifts” in the credit market is likely to explain that credit growth might have positive or negative effect on credit w n quality These three shifts are generally known as: (i) a supply shift (an expansion in lo ad bank loan supply by lowering credit standards), (ii) a demand shift (an increase in ju y th loan demand to optimize business activities) and (iii) productivity shift (a positive change in macroeconomic conditions) In addition, empirical evidence confirms that yi pl rapid credit growth of commercial banks could lead to a deterioration or al ua improvement of credit quality The macroeconomic context for banking industry n indicates that the decline in credit quality after a period of growth might be a va n reflection of (1) negative changes in the macroeconomic determinants which have a fu ll bad influence on the business activities of borrowers; and (2) information m oi externality which makes banks hardly gain efficiency in evaluating their customers nh at This study

INTRODUCTION t to ng 1.1 PROBLEM STATEMENT hi ep Commercial bank is one of the most important financial intermediaries in the w economy Their main functions are mobilizing and lending money to allocate n lo financial resources for households, firms and other economic entities The typical ad problem of banks is that when borrowers could not use well the money they had y th ju borrowed, a credit risk arose One of the main causes is that banks lower their credit yi standards to attract more borrowers Although it might be a good opportunity to pl ua al boost credit growth in the present time, banks will face a higher probability to deal with non–performing loans (NPLs) in the future However, if loans expansion is due n n va to an increase in the demand, this growth will not essentially lead to bad loans oi m circumstances ll fu Therefore, credit growth may be a reflection of credit quality under some nh When the economy is in the stage of recession, it is certain to affect negatively at z on the financial market especially the banking system The general picture is that z ht vb commercial banks attempt to boost credit growth for profit objective whereas jm households and firms who borrow money from banks have to face with difficulties k in business activities This leads to a consequence that credit growth may reduce gm credit quality The problem is whether the profit target of commercial banks by om l.c boosting credit growth would be efficient or it just increases the NPLs which bring no profits or even losses a Lu n The determination of the effect of credit growth on credit quality is getting lending activities For central bank, it will help to control the loans growth of y time of loosening or tightening credit standards and the decision to expand or limit te re policy makers For commercial banks, it may help them to consider the appropriate n va more and more important for not only commercial banks but also central bank and In addition, the “too–big –to–fail” hypothesis contributes to marginal effect of credit growth on credit quality The coefficient of credit growth 𝐂𝐑𝐄𝐃𝐈𝐓 with its t to interactive term 𝐂𝐑𝐄𝐃𝐈𝐓 × 𝐋𝐀𝐑𝐆𝐄𝐒𝐓, is interpreted as follows: ng hi ep 𝟒 𝟒 ∑ 𝛄𝐣 ∆𝐂𝐑𝐄𝐃𝐈𝐓𝐢𝐭−𝐣 + ∑ 𝛅𝐣 ∆(𝐂𝐑𝐄𝐃𝐈𝐓𝐢𝐭−𝐣 × 𝐋𝐀𝐑𝐆𝐄𝐒𝐓𝐢𝐭 ) w 𝐣=𝟏 𝐣=𝟏 n 𝟒 lo ad = ∑(𝛄𝐣 + 𝛅𝐣 𝐋𝐀𝐑𝐆𝐄𝐒𝐓𝐢𝐭 )∆𝐂𝐑𝐄𝐃𝐈𝐓𝐢𝐭−𝐣 , ሺ10ሻ ju y th 𝐣=𝟏 yi If 𝐋𝐀𝐑𝐆𝐄𝐒𝐓 = 1, the coefficient of 𝐂𝐑𝐄𝐃𝐈𝐓 would be (𝛄𝐣 + 𝛅𝐣 ) and the pl ua al variance is calculated as 𝐕𝐚𝐫(𝛄𝐣 + 𝛅𝐣 ) = 𝐕𝐚𝐫(𝛄𝐣 ) + 𝐕𝐚𝐫(𝛅𝐣 ) + 𝟐𝐂𝐨𝐯ሺ𝛄𝐣 , 𝛅𝐣 ሻ n The long–run coefficient of 𝐂𝐑𝐄𝐃𝐈𝐓 corresponding to 𝛄𝐣 and 𝛅𝐣 is calculated va n as formula (7), the variance is in formula (8) In the case of long–run coefficient of fu ll (𝛄𝐣 + 𝛅𝐣 ), the formula would be calculated as: oi m at 𝛄𝐋𝐑 + 𝛅𝐋𝐑 𝟒 nh 𝟒 𝟏 𝟏 =( × ∑ 𝛄𝐣

findings hi ep According to the estimation result, credit growth has negative effects on credit quality at the lag level of and and the long–run coefficient of credit growth is w n also statistically significant This proves for the existence of supply shift and the lo ad information externality in the credit market, and the negative impact from the ju y th macroeconomic conditions yi Figure 4.1 is to compare the growth rate of deposit liabilities of Dong Nai pl ua al banking system (the growth rate data only capture commercial banks’ branches which were in Dong Nai from 2010Q1 to 2014 Q4) with the quarterly deposit n n va interest rate in Viet Nam As can be seen from the figure, the condition stated in the ll fu literature is hold when the deposit growth rate is higher than deposit interest rate It oi m implies the inexistence of potential shock or vulnerability of Dong Nai banking system Therefore, credit growth has not been a great concern for commercial banks nh at during this period However, this figure only brings some evidences to confirm that z z net resource might be transferred in the direction from depositors to banking vb system If credit growth does not perform well, it would become a large pressure for ht k jm commercial banks to boost their mobilizing activities in the future, which could gm disrupt the condition of deposit growth rate and interest rate and reverse

the estimation result of one–step Difference GMM method with robust standard errors First, test for second order autocorrelation AR(2) shows t to that 𝛆𝐢𝐭−𝟏 does not correlate with 𝛆𝐢𝐭−𝟐 due to an existence of the high p–value ng hi obtained from the analysis Test for first order correlation AR(1) is as expected with ep small p–value (lower than 0.05) Therefore, the tests for instrument variables are w valid Second, both Sargan Test and Hansen Test provide very high p–value, which n lo proves that the null hypothesis of valid instrument variables might not be rejected ad These tests indicate that the problem of endogeneity would be solved and the y th coefficients in the model could be used for further analysis ju yi According to the estimation results, the coefficients of lagged independent pl ua al variable (∆𝐍𝐏𝐋_𝐒𝐋𝐢𝐭−𝟏 ) is positive and significant, so credit quality in the present n might associate with itself in the past It means higher (lower) credit quality might va lead to higher (lower) credit quality after one quarter of a particular year The n ll fu lagged variables of credit growth are also positive and significant at lag level of oi m and It means the decision of expanding lending activities of commercial banks in at nh Dong Nai has negative influence on credit quality after three quarters to one year As stated in the Circular No 02/2013/TT–NHNN, customer loans will be recorded z z as NPLs if they are overdue from 91 days and above It is about two–quarter shorter vb ht than the two significant lag levels of credit quality Therefore, new loans of jm commercial banks in Dong Nai might have very high chance of becoming NPLs k gm after two quarters from the overdue threshold In the shorter period of one and two om l.c quarters, the effect of

relationship between credit k growth and credit quality of commercial banks in Dong Nai, which is represented in gm l.c both short–run and long–run timeframe This relationship reflects two main implications First, based on the literature, there may be a supply shift in the loan om market It appears that commercial banks in Dong Nai are willing to lower their a Lu credit standards in order to boost lending activities This action from the n activities of the economic entities, especially households and small and medium 44 y from the macroeconomic conditions which result in disadvantages for business te re have bad financial capacity Second, there would be the existence of adverse effects n va commercial banks results in the high chance of lending money to borrowers who enterprises They would hardly gain positive cash flows to finance their liabilities Thus, overdue loans increase Third, there would be the existence of information t to externality in the loan market Commercial banks in Dong Nai may mis–evaluate ng hi their new customers Firms, households and other borrowers may be able to ep approach many sources of loans, so they can use borrowed money from somewhere to pay the debts in somewhere else w n lo The effect of credit growth on credit quality is not adjusted by the ad y th characteristic of large bank size This proves for the inexistence of “too–big–to– ju fail” hypothesis in the case of commercial banks in Dong Nai Although some yi banks have much larger size than others, they seem to have partially similar credit pl ua al growth policy In the aspect of this hypothesis, it means that large banks not have n over–confidence psychology (which makes bank believes in the protection of The va State Bank of Vietnam) in lending activities In more details, banks whether large or n ll fu small size have the same change in credit quality corresponding with their change in oi m credit growth This is contrary to the expectation that larger banks often suffer from nh greater change in credit quality than the smaller banks Vietnam banks in general at and Dong Nai banks in particular play a very important role in the financial market z z If one of them collapses, it would influence other banks due to the problems of vb ht cross–deposit among banks and negative psychology of people, and the whole jm Vietnam banking system would be in trouble Therefore, it may not reasonable to k gm conclude that commercial banks not believe in the intervention from The State l.c Bank to prevent them from failure In the scope, methodology and available data of om this research, there is temporarily no evidence to confirm this hypothesis n a Lu n va y te re 45 CHAPTER CONCLUSIONS t to ng The relationship between credit growth and credit quality could be explained hi ep through three shifts in the loan market First, the supply shift represents for the fact that banks expand their lending activities by lowering their credit standards In these w n circumstances, banks will face a high probability of lending money to bad lo ad borrowers Second, the demand shift originates from the demand of the capital ju y th restructuring as well as taking advantage of the lower cost capital from banks than somewhere else in capital market Banks would tighten their credit standards for yi pl this shift, which reduces credit risks in the future Third, the productivity shift in al ua favorable conditions of the economy reflects the efficient business activities of n households, firms and other economic entities who had borrowed money from va n banks The ability of financing the debts would be improved In addition, the fu ll negative nexus between credit growth and credit quality is also explained by m oi adverse macroeconomic shocks on borrowers and the information problems, in at nh which banks misevaluate new customers and as a consequence, the banks not z take any care of negative effects of their loans on other banks’ information z vb In accordance with the empirical results obtained from this study on the ht k jm sample of 29 commercial banks in Dong Nai from 2009Q3 to 2014Q1, credit gm growth has negative effect on credit quality in both short run and long run This l.c partially proves for the existence of the supply shift in the loan market in the context om of Dong Nai Commercial banks in Dong Nai appear to lower their credit quality in a Lu this researched period to boost lending In addition, the local economy of Dong Nai is not a good environment for business activities Moreover, the credit externality n n va may exist in the loan market These findings may derive some policy implications y te re which can be presented as follows: 46 For the Commercial banks t to It is not the right time for boosting credit growth rapidly in Dong Nai The ng commercial banks have to be more cautious in appraising investment projects, hi ep evaluating collaterals and supervising their customers’ capital usage especially new customers in order to avoid bad borrowers Moreover, commercial banks should w focus greatly on projects on advantageous fields in Dong Nai such as agriculture, n lo production of exports, labor intensive and high technology industries In the ad y th relationship with customers, they should deploy and maintain solutions for their ju customers to overcome difficulties in business activities; and classify borrowers yi depending on their state of credit relationship to apply appropriate incentive pl ua al policies In addition, commercial banks need to control new NPLs, continue to n handle old NPLs and prepare sufficient provision for credit risk Finally, va commercial banks should keep track of the state of the local economy to implement n ll fu credit policies timely and efficiently m oi For The State Bank of Vietnam, Dong Nai branch (SBV–DN) nh at The State Bank of Vietnam, Dong Nai branch (SBV–DN) needs to supervise z z more closely on credit growth of commercial banks, especially commercial banks vb ht with high NPL ratio Most importantly, the SBV–DN should classify commercial k jm banks into groups based on their lending activities to target the appropriate rate of gm credit growth, avoiding high credit risk of weak commercial banks In addition, the l.c SBV–DN has to catch up with the conditions of local economy as well as the real om state of commercial banks’ activities in order to enhance the efficiency of a Lu administration and operation Finally, they should co–ordinate with the local n governments at various levels to improve local economy, create good business n va environment for commercial banks, households and enterprises y te re 47 For local government at various levels t to Local governments should ease the legal environment for commercial banks, ng households and enterprises First, they need to facilitate households and enterprise hi ep in the proceedings of business registration Second, they could co–ordinate with relevant departments to support for enterprises’ outputs and stabilizing the markets w Last but not least, they could direct Executive Office to speed up process of n lo recovering NPLs This would help commercial banks in injecting capital into the ad ju y th market continuously, which stimulates the local economy yi In addition to the main empirical findings, this research still has some pl limitations First, the research scope is only in Dong Nai province Hence, the result al n ua will not reflect the convincing outcomes for the whole banking system in Vietnam va Second, the period of available data is not sufficient to capture the lags of very long n time There are many former researches which indicated that the effect of credit fu ll growth on credit quality may be even three years Further studies may use data of m oi yearly financial statements and the scope for commercial banks in Vietnam and at nh other countries in the world z z ht vb k jm om l.c gm n a Lu n va y te re 48 REFERENCES t to
