crisis that the world is experiencing Since granting credit is one of the main sources of income in commercial banks, the management of the risk related to that credit affects the profitability of the banks The study evaluates the impact of credit risk on profitability in Commercial Banks in Vietnam for the period of 2005-2009 Using financial ratios such as Return on Asset (ROA), Return on Equity (ROE), Nonperforming loan (NPL) analyze In the study try to find out how the credit risk management affects the profitability in banks The study is limited to identifying the relationship of credit risk management on profitability of twenty commercial banks in Viet Nam The results of the study are limited to banks in the sample and are not generalized for the all the commercial banks in Viet Nam Furthermore, as the study only uses the quantitative approach and focuses on the description of the outputs from SPSS, the reasons behind will not be discussed and explained The quantitative method is used in order to fulfill the main purpose of the study The study have used regression model to the empirical analysis In the model the study have defined ROE as profitability indicator while NPLR and CAR as credit risk management indicators The data is collected from the sample banks annual reports (2005-2009) and capital adequacy and risk management on financial reports (20052009) in twenty commercial banks The findings and analysis reveal that credit risk has effect on profitability in all twenty banks Keywords: credit risk management, profitability, banks By: Tran Quoc Trong Master’s

In this chapter, we present the background of the thesis followed by the problem statement The discussion also contains the motivation for our thesis Finally, we present the research question, the purpose of this thesis and limit the area of the study 1.1 Statement of problems Credit activities are crucial of Vietnam banking system, They bring 80-90% to income for each bank, but the risks are not less Credit risk will be higher than the enormous influence to business banking Facing the opportunities and challenges of the process of international economic integration, the issue of raising the competitiveness of the domestic commercial banks with foreign commercial banks, in particular improving the quality of credit, risk reduction has become urgent Besides, the world economic situation is complicated and the risk of increasing the credit crisis Vietnam is a country with open economy should not avoid the effects of the world economy Facing this situation, requires commercial banks of Vietnam must improve the management of credit risk, limited to the minimum possible risks, causing potential risks Managing credit risk in financial institutions is critical for the survival and growth of the financial institutions In the case of banks, the issue of credit risk is even of greater concern because of the higher levels of perceived risks resulting from some of the characteristics of clients and business conditions that they find themselves in Credit risk refers to the risk of loss because of debtor’s non-payment of a loan or other forms of credit As they default, delay By: Tran Quoc Trong Master’s thesis Supervisor : Dr Pham Huu Hong Thai in repayments, restructuring of borrower repayments and bankruptcy are also considered as additional risks When it comes to banking, credit risk is apparent on lending services to clients There is the need for an effective employment of credit scorecard for the purpose of ranking potential and existing customers according to risk In this will be based the appropriate measures to be applied by the banks Nevertheless, banks charge higher price for higher risk customers Credit limits and faced by lenders to consumers, lenders to business, businesses and even individuals Credit risks, nevertheless, are most encountered in the financial sector particularly by the institutions such as banks Credit risk management therefore is both a solution and a necessity in the banking setting The global financial crisis also requires the banks to regain enough confidence by the public not only for the financial institutions but also the financial system in general and to not just rely on the financial aid by the governments and central banks It is critical for the banks to engage in better credit risk management practices Banks are not an exemption The banks of Vietnam as well as the other over all the World are required to follow Basel II capital adequacy framework from 2007 Basel II aims to build on a solid foundation of prudent capital regulation, supervision, and market discipline, and to enhance further risk management and financial stability However, it is worth mentioning that regulatory and deregulatory transitions usually end up with the same result The exposed risk – the main and most difficult one to identify – is the credit risk in the particular current case The importance of this risk is increased by the fact that it is linked to the problem of collateral Therefore, it is in need of being deliberately examined and studied For this reason, Basel II considers varieties of credit risk measurement techniques, wider than Basel I did The goal is to improve the credit risk By: Tran Quoc Trong Master’s thesis Supervisor : Dr Pham Huu Hong Thai management quality without constraining banks’competitiveness Regulations should be interactive or flexible to be successful because of rapidly changing technological, political, and economical circumstances Credit risk measurement tools presented in Basel II intended to be flexible The banks can either choose from the proposed options or employ their own as long as it gives sound and fair results The importance of the credit risk management and its impact on profitability has motivated us to pursue this study We assume that if the credit risk management is sound, the profit level will be satisfactory The other way around, if the credit risk management is poor, the profit level will be relatively lower Because the less the banks loss from credits, the more the banks gain.The profitability is the indicator of credit risk management The central question is how significant is the impact of credit risk management on profitability 1.2 Problem Discussion The importance of the credit risk and its impact on profitability has motivated us to pursue this study We assume that if the credit risk management is sound, the profit level will be satisfactory The other way around, if the credit risk management is poor, the profit level will be relatively lower Because the less the banks loss from credits, the more the banks gain Profitability is the indicator of credit risk management The central question is how significant is the impact of credit risk management on profitability This thesis is an endeavor to find the answer 1.3 Research question The discussed background and problem formulation make us to have the following research question: How does credit risk affect the profitability in commercial banks in Vietnam ? 1.4 Objective of the study By: Tran Quoc Trong Master’s thesis Supervisor : Dr Pham Huu Hong Thai The purpose of the research is to describe the impact level of credit risk on profitability in twenty commercial banks in Vietnam The study is to test the following hypothesis by econometric model : H1: Banks with higher profitability (ROE, ROA) have lower loan losses (NonPerforming Loans/ Total Loans) H2: Banks with higher interest income (net interest/Average total assets, interest net /total income) also have lower bad loans (NPL) H3: The growth of ROE/ ROA may also depend on the capitalization of the banks and operating profit margin If a bank is highly capitalized through the risk-weighted capital adequacy ratio (RWCAR) or Tier capital adequacy ratio (CAR), the expansion of ROE will be retarded we test the hypothesis using the following regression model: P(ROA/ROE)= α+β1NPLR+ β2CAR+ ε Using data on 20 commercial banks in Vietnam and our results show no rejection by ourhypothesis 1.5 Scope of the study The research is limited on evaluate the impact of credit risk on profitability in the twenty Banks in Vietnam Thus, the other risks mentioned in Basel Accords are not discussed Due to the unavailability of information in annual reports, our sample only contains twenty largest commercial banks and their years’ annual reports from 2005 to 2009 respectively Since the banks in sample rejected to participate in our internet based survey, the primary data was not possible to obtain Considering the above mentioned circumstances, the results of the study are limited to twenty commercial banks in the sample and are not generalized for all the banks in Vietnam Finally, as the study only uses the quantitative approach and focus on the description of the outputs from By: Tran Quoc Trong 10 Master’s thesis Std Residual Regression [DataSet1]
