Based on related theories and previous research surveys on credit risk provision along with different estimation methods/models, the article has shown the factors affecting credit risk provision of Vietnamese commercial banks. The results of the study found that marginal net interest income, non-performing loan ratio, and bank size have the same impact as the credit risk provision ratio, while income on total assets has a negative impact on the bank's credit risk provision ratio. With the results of the study, the study provided information on factors affecting the credit risk provision of commercial banks. Since then, it has made useful contributions to agencies and managers to propose policies to improve credit risks at Vietnamese commercial banks. Keywords: Credit risk, bad debt, macro factors, internal factors of banks. 1 1. Introduction ______________________________________________________________________________________ According to Timothy & MacDonald (1995), credit risk is a potential change in net income and market value of capital resulting from non-payment or late payment. According to the Basel Supervisory Commission defines credit risk as the possibility that a borrower or a bank's partner fails to comply with agreed repayment terms. Credit risk, also known as default risk, arises from uncertainty associated with non-repayment of debts on the part of customers to the bank. According to Circular No.11/2021/TT-NHNN, credit risk in banking activities is a potential loss to debts of foreign credit institutions and bank branches due to customers' failure to perform or inability to fulfill part or all of their obligations as committed. In the period of 2007-2008, the world economy experienced a dark period with a mass breakdown in the banking system, widespread credit "hunger", falling stock prices and large-scale devaluation of currencies in the US and many European countries. The origin of this great recession was the real estate bubble along with the system of monitoring and early warning of incomplete credit risks in the United States. The collapse of these bubbles has led to many investors losing the ability to pay loans to banks and financial institutions, leading to a widespread credit crisis. In Viet Nam, many risks have been revealed during the period of hot credit growth, since 2012, the State Bank of Vietnam (SBV) has begun to strictly control the credit growth of the banking sector and considers this an important tool in managing monetary policy. Since then, the financial situation and business activities of each commercial bank have become the basis for the SBV to assign specific credit growth targets every year. On the part of commercial banks in recent times, the structure of revenue sources has expanded and the proportion of non-interest revenues has increased. However, with the characteristics of financial intermediaries in banking business, lending is still a key business of the bank and credit risk always plays a dominant role in the health and operation of the bank. Appropriately controlled credit risk from a national perspective will greatly support economic growth, from a banking perspective, it will help them achieve good profits from the main business. Non-Performing loans in Vietnam over the past time have been controlled quite well, always below 3% of the total outstanding debt, but there is always a risk of increasing due to credit growth pressures, limitations in the management capacity of commercial banks themselves, and external macro factors such as inflation, exchange rate,... In the context that lending is always an important channel of operation of banks and the economy, and there are requirements for a transparent and unified credit management mechanism, it is necessary to understand the factors affecting credit risk, in accordance with the practice of state management and business development of social resources. This 2 fact shows the need to study the factors affecting the Credit Risk of Vietnamese commercial banks, especially when the NPL has gradually risen recently. Stemming from that important awareness of theory and practice, authors chose the topic “FACTORS AFFECTING CREDIT RISK OF COMMERCIAL BANKS IN VIETNAM PERIOD 2012-2021” for this research. 2. Literature review __________________________________________________________________ 2.1 Theoretical review 2.1.1 Dependent variable - Non-performing loans is one of the main causes of credit risk. They are debts that are overdue for more than 90 days and are doubted about the ability to repay debts and the ability to recover capital of creditors due to continuous losses of debtors, declaring bankruptcy or having dispersed assets, insolvency... Non-performing loans will clearly reflect the credit quality of the bank, based on the overdue time and repayment ability of customers to classify bad debts into 3 groups: group 3 (subprime), group 4 (doubtful debts) and group 5 (loss debts). Non-performing Loan Ratio is determined by dividing the NPL, calculated by summing the three types of bad debts, by the total amount of outstanding loans in the bank's portfolio, according to Decision 11/2021/TT-NHNN, this ratio is used to evaluate the credit quality of credit institutions. 2.1.2 Independent variables Macroeconomic variables - Economic growth: A healthy economy makes it easier for people and businesses to pay off their obligations or guarantees that they will be able to return their liabilities. The ability of borrowers to repay debts declines or becomes insolvent owing to bankruptcy and losses, however, when a slowdown in GDP growth denotes an economic downturn, which increases credit risk. - Inflation rate: According to the IMF: "Inflation is the rate of increase in prices over a given period of time. Inflation is typically a broad measure, such as the overall increase in prices or the increase in the cost of living in a country". When there is significant inflation, the borrower's real income is reduced while the amount of interest due rises because the interest rate is also high at this time, which could affect the borrower's ability to repay the loan or force them to become insolvent, increasing the number of bad debts. - The nominal interest rate (NIR): The nominal interest rate is the amount of domestic currency needed to buy a certain amount of foreign currency. Nominal currency 3 appreciation is the term used to describe a decline in this variable. Nominal currency depreciation is the phrase for an increase in this variable. Interest rates have a direct impact on the borrower's capacity to repay the loan; specifically, when the interest rate rises, the borrower is put under more pressure to make repayments because the amount of interest that must be paid also rises. Losses for the bank happen if the interest rises above the borrower's capacity to repay the loan. Theoretically, INR has a favorable effect on credit risk. - Exchange rate: The exchange rate is the price at which at a time the currency of one country or region can be converted to the currency of another country or region. Accordingly, the exchange rate is calculated in the number of local units per unit of foreign currency. When the local currency depreciates, the local currency is reduced in the rain, as a result, the price of imports becomes more expensive, leading to an increase in production costs and indirectly increasing the consumer price index, inflation is at risk and businesses are highly dependent on raw materials, imported ancillary or intermediate products will have to bear a debt burden when the cost of borrowing increases. From there, Credit risk tends to increase. Therefore, it is assumed that EXR may have a similar or diametrically opposed impact on credit risk. Intrinsic variables - Bank size: Bank size is the market value of the bank, studies are usually measured by the logarithm of the bank's total assets to adjust this variable to the same value as other variables in the model. Bank size can affect bad debts in both positive or negative ways. Large banks are able to manage non-performing loans more effectively thanks to their diversification of loan portfolios and superior Credit Risk management compared to small banks (Das & Saibal, 2007). However, theoretically, large-scale banks frequently have a high non-performing loan ratio because they believe that due to their size, they cannot be at risk, making it simpler to make loans and resulting in a lot of bad debt. According to the notion, bad debt and the size of the bank have similar effects. - Capital structure: A combination of equity and loans from banks or financial institutions to increase profit margins for businesses. Previous studies have often used the ratio of equity to total assets as a proxy for the level of capitalization. Delis, Tran, and Staikouras (2011) argue that higher financial leverage, due to stricter capital requirements, implies that banks are being more cautious in their lending behavior. On the other hand, low financial leverage leads to an increase in bad debt, as bank managers have the ability to encourage moral hazard, by increasing loan portfolios when banks are undercapitalized. - Loan-to-Deposit Ratio: According to the State Bank of Vietnam: "LDR (Loan to Deposit Ratio) is the ratio of credit balance to mobilized capital, the index is calculated by dividing the number of loans to customers to divide by the bank's working capital". 4 LDR is one of the important indicators used to assess the safety of banks. When loans are higher than bank deposits, to avoid showing that they are trying to attract capital from outside, banks will have the incentive to reduce their risk provisioning ratio. - Profitability of Banks: ROA is an important indicator of the profitability of the bank. It shows the profit earned per dollar of assets and reflects the bank's ability to manage resources to make a profit. There have been quite a few studies conducted and the results prove the opposite relationship between profitability and bad debt. Dimitrios et al. (2010) argue that mismanagement is associated with poor skills in credit scoring, collateral appraisal, and commitment to monitoring borrowers. Meanwhile, Zribi et al. (2011) argue that a highly profitable bank is less likely and motivated to generate income, so it is less likely to engage in risky lending activities. - Non-interest income (NII): is calculated as non-interest income divided by total income. This strong indicator will lessen the pressure to maximize credit profit, which will lessen Credit Risk. The influence of NII on Credit Risk is thought to be reversed. - Loan Loss Provisions (LLP): An item on the income statement designated as a reserve for unpaid loans and loan payments is known as a loan loss provision. This clause is used to cover a variety of loan losses, including non-performing loans, bankruptcies of customers, and loans that are renegotiated and have lower payments than originally anticipated. Loan loss reserves, a balance sheet item that represents the entire amount of loan losses deducted from a company's loans, are increased by loan loss provisions.The indicator used by banks to ensure loan risks and control losses is Loan Loss Provisions/Total Assets. High-risk provision indicates that the bank has a high credit risk (represented by a bad debt ratio). Therefore, the hypothesis is that LLP has the same impact as the bad debt ratio. The level of provisioning is specified in Article 12 and Article 13 of Circular 11/2021/TT-NHNN as follows: Specific provision: The specific level of provisioning is calculated according to the formula: , inside: R: is the total amount of specific provisions that must be deducted from each customer; The sum of the pi chains where i runs from 1 - n: is the sum of the customer's specific room from the letter balance 1 to the nth. Ri: the total amount of specific provisions to be deducted by the customer for the principal balance of the first debt. The formula for calculating Ri = ( Ai - Ci) x r. Where: Who is the first principal balance. Ci is the collateral deduction value of the i. If Ai < Ci 5 then R = 0. r is a group-specific provisioning rate. The provisioning ratio for each debt group is as follows: - Debt in group 1, r = 0% - Debt of group 2, r = 5% - Debt in group 3, r = 20% - Debt of group 4, r = 50% - Debt of group 5, r = 100% - General provision: The amount set aside for general provision is determined to be equal to 0.75% of the total balance of debts from group 1 to group 4 except for the following items: + The money is deposited at credit institutions, foreign bank branches in accordance with the law or deposits at overseas credit institutions. + Loans or term purchases of valuable papers between credit institutions and foreign bank branches in Vietnam. + Purchases of promissory notes, bonds, bills and certificates of deposit issued domestically by credit institutions and branches of foreign banks in Vietnam. + The purchase and resale of Government bonds on the stock market shall comply with the law on issuance, registration, depository, listing and trading of government debt instruments on the stock market. 6 Table 1: Research variables and hypotheses in the research model Classify Names of elements Ampersand Formula RGDP Gross Domestic Product Growth Rate - Inflation Expected sign A.

Dependent variable Model Non-Performing Loan Ratio NPL (Sub-standard debts + Doubtful debts + Loss debts) /Gross loans Source: Team of authors compiled from the study overview 7 2.2 Extant literature review 2.2.1 Previous research related to the macro variables According to the theory of economic cycle and consumption model by Modigliani and Miller (1967), economic growth, enterprises are easier to repay loans from commercial banks due to opportunities for investment and business prospects more favorable. However, the study of Schechman and Gaglianone (2011) shows a positive correlation, suggesting that continued economic growth will probably make banks more dependent and will lend more easily, the risk of credit risk increases. Rising inflation reduces the real value of loans and reduces defaults (Jabra et al., 2017). On the other hand, inflation devalues the currency, reducing the rate of return in general. When inflation increases, the correlation leads to an increase in interest rates due to tight monetary policy. Along with other costs, the cost of debt services also increases, businesses and borrowers may have difficulty repaying (Le Ba Truc, 2018) When real interest rates rise, borrowing costs increase, making the profitability of investments lower, leading to an increase in bad debts, especially for loans. has a floating interest rate, due to a decrease in the borrower's ability to meet its obligations. (Ahlem et al., 2013) When the domestic currency depreciates, the purchasing power of the domestic currency decreases, making imported goods more expensive, which will increase production costs and indirectly increase the consumer price index. occurs and businesses that depend on imported raw materials, auxiliary materials or intermediate products will have to incur a debt burden when the cost of borrowing increases. Since then, credit risk tends to increase. 2.2.2 Previous research related to the micro variables Das & Saibal (2007) supposed that large banks can manage bad debts more effectively thanks to their superior ability to diversify their loan portfolios and credit risk management capabilities compared to small banks. However, large banks may also be willing to accept high risks due to the expectation that they will be protected by the government if danger occurs, leading to a higher NPL ratio (Nguyen Thuy Duong & Tran Thi Thu Huong, 2017). Previous studies often used the ratio of equity to total assets as a proxy for the level of capitalization. Delis, Tran and Staikouras (2011) suggest that higher financial leverage, due to stricter capital requirements, implies that banks are more cautious in lending behavior. In contrast, low financial leverage leads to an increase in bad debts, because it is easy for bank managers to encourage moral hazard, increasing loan portfolios while banks are not sufficiently capitalized. 8 To measure a bank's profitability, studies often use ROA (Return on Assets) or ROE (Return on Equity), which implies the extent to which management is efficient in using assets and equity to generate income. Many studies demonstrate a negative relationship between profitability and bad debt. Dimitrios et al. (2010) suggest that poor management is related to poor skills in credit scoring, collateral appraisal and commitment to monitoring borrowers. Meanwhile, Zribi et al. (2011) argue that a bank with high profitability has less incentive to generate income, therefore, is less constrained when engaging in profitable lending activities risk. Some other empirical studies by Berger and DeYoung (1997), Bikker and Hu (2002), Pain (2003), Jimenez and Saurina (2006) and Quagliariello (2007) have shown bankspecific factors such as size, efficiency, and credit quality are important determinants of bad debt, because they can cause loans to be risky. Godlewski (2004) uses return on assets (ROA) as an efficiency indicator. He shows that the impact of bank profitability is negative on NPL ratio. However, by studying 129 Spanish banks for the period 1993-2000, Garcıa-Marco and M. Dolores RoblesFernandez (2008) show a higher return on equity (ROE) followed by future risks. They argue that the policy of profit maximization comes with a high degree of risk. Sinkey and Greenwalt (1991) studied the losses of the banking industry in the United States. The author asserts that internal and external factors explain the loss rates of these banks. These authors found a significant positive relationship between loan loss rate and intrinsic factors such as excessive lending, high-interest rates. Similarly, Pesola (2007) suggested that loan losses are the main factor affecting the operation of credit institutions. He used macroeconomic variables to explain the distribution of losses. Loan loss provisions (LLPs) reflect the overall attitude of the banking system to control risk. LLP is calculated according to the amount of provision for credit risk. Terms are determined based on the agency's historical experience in the field. Hasan and Wall (2004) used a sample of banks from 24 countries for the period 1993-2000; They found that higher nonperforming loans were associated with higher LLPs. Boudriga et al. (2009) studied the determinants of NPL and the impact of environmental monitoring for the period 2002-2006 for a sample of 59 countries. The authors found that a high contingency seems to reduce bad debt levels. They also found a link between bad loans and bank-specific variables such as the percentage of total assets that were rated as risky. 9 3 . Methodology _____________________________________________________________________ 3.1 Research Data Research data were collected as follows: Statistics were traced from Bankscope, Vietnam banks dataset (source: IBT), from statistics report statistics of the State Bank of Vietnam (SBV), and from the audited financial statements of banks in Vietnam from 2012 to 2021. Macro data was retrieved from the World Bank, from the General Statistics Office of Vietnam, and from the SBV during the same period. 3.1.1 Micro factors Obtained from the audited financial statements of 17 commercial banks (see the list in Appendix 2) in the research sample, annual report or Bankscope for bad debt (NPL) element in case it is not found in the financial statement due to lack of explanation. Research data was collected during the period from 2007 to 2018. As for the bank's internal factors, after collecting, the author calculates as follows: Table 2: Internal factors Factors Names of parameters collected on financial statements of Vietnamese commercial banks (1) Measurement (2) NPL = Sub-standard debts + Doubtful debts + Gross loans Loss debts (1)/(2) Size Total assets Log(1) Capital structure Total Equity Total Assets (1)/(2) Loan-to-Deposit rate Total loans Total deposit (1)/(2) NII ratio Non-interest income Total income (1)/(2) ROA Net income Average total assets (1)/(2) NPL ratio Intrinsic factors Source: Team of authors compiled from the study overview 10 3.1.2 Macro factors Data on macro factors are retrieved from the World Bank during the period 2012 - 2021 as follows Table 3: The Macroeconomic Factors Factors Names of parameters collected on financial statements of Vietnamese commercial banks Macro factors (1) (2) Economic growth Gross Domestic Product Growth Rate Inflation Inflation Inflation (1) The nominal interest rate The nominal interest rate (1) Exchange Rate USD price index at t-100 (1) Measurement (1)-(2) Source: Team of authors compiled from the study overview 3.2 Research Methodology Quantitative research methodology: Using Pooled OLS, FEM, and REM models and using GLS method to solve heteroskedasticity and correlation errors and table data to measure the influence of macro factors and intrinsic factors to NPL ratio. In addition, the authors use the analytical method to interpret the results obtained from the quantitative method to describe these effects better.

Results _____________________________________________________________________ The regression model follows the methodology in the Hasna Chaibi and Zied Ftiti (2015) research model and takes the following form: NPLit = α++ β1LLPi,t + β2ETAi,t + β3NIIi,t + β4SIZEi,t + β5ROAi,t + β6LDRi,t + β7RGDPt + β8INFt + β9INRt + β10EXRt + vi + εi,t First, the author uses quantitative methods to find the factors that influence and the level of influence of these factors on credit risk at Vietnamese commercial banks. To estimate the model, initially using the table estimation technique for Pooled models, FEM model and REM model. But due to the heteroscedasticity appearance in the model, GLS method regression on the table data will be used. Table 5: Descriptive statistics table Source: Team of authors compiled from the study overview Results from the Correlation Coefficient Matrix Table show that the correlation coefficient between variables is quite low (<0.8). So the authors assume that there is no multicollinearity between variables. However, to ensure accuracy, the authors decided to use the variance magnification factor to check. 13 Table 6: Correlation coefficient matrix Source: Team of authors compiled from the study overview The Variance Inflation Factors are used by the authors to test the phenomena of multicollinearity. The authors came to the conclusion that there was no multilinear phenomenon because the results showed that all variables had values lower than 10. Table 7: Table of Variance Inflation Factors (VIF) Source: Team of authors compiled from the study overview The authors used the F-test to make a comparison between Pool and FEM. After running the data, F-test results that all u_i=0: F(16, 143) = 2.26 Prob > F = 0.0059. Thus, the authors concluded that the FEM model is better than the Pooled OLS model. Then, run the Breusch_Pagan Lagrange Multiplier test with xttest0 command to compare between the REM model and the Pooled, obtaining the result chibar2(01) = 5.80 Prob > chibar2 = 0.0080. Thus, the authors decided to choose the REM model. 14 Finally, the authors used the Hausman test to determine between FEM and REM. Prob > chi2 = 0.7336 (greater than 10%). So the REM model is a suitable model for the research of the authors. After selecting the REM model, the authors found that the model had defects. It is the phenomenon of First order autocorrelation and Heteroskedasticity. The authors used the GLS model to overcome the defects just mentioned. The following regression results are obtained using the GLS model: Table 8: Regression results Source: Team of authors compiled from the study overview (1) Pooled-Ols (2) FEM Model (3) REM Model (4) GLS Model 15 According to the regression results table above, the intrinsic factors, such as Loan Loss Provisions (LLP), Non-Interest Income (NII), Bank Size (SIZE), Equity to Assets (ETA), Loan to Deposit (LDR), and Return on Assets (ROA), as well as the banks' macro factors, such as GDP growth, inflation, and exchange rates, are both statistically significant factors that affect credit risk. - Bank Size has a negative impact on the current year's NPL at a significant 1%. - ROA acts in the opposite direction on NPL with a meaningful level of 5%. - LLP Ratio is the most impactful and in the same direction as NPL with a significance of 1%. - NII Ratio has the same impact on NPL with a significance of 5%. - GDP Growth has the same impact as the meaningful level of 1%. - INF has a concurrent impact with a 1% significance level. The regression results also showed that the LDR, ETA, NII, and EXR variables had little impact and were not statistically significant. 5. Conclusion _____________________________________________________________________ 5.1 Intrinsic factors The authors found that the Bank Size (SIZE) outcome had a relevant amount of 1% negative influence on NPL after running the model. In other words, the credit risk lowers as bank size grows. The authors' initial expectations were not met by this outcome. In order to explain this outcome, the author claimed that the SBV had requested a significant expansion of Vietnamese commercial banks, but that this expansion had not raised credit risk because the SBV had also been successful in controlling credit growth without affecting credit quality. On the other hand, in order to grow in size, banks must also raise earnings. To this end, banks have increased their non-credit income, which has eased the strain on credit and decreased credit risk. Return on Assets (ROA) has a negative effect on NPL ratio (NPL) with a statistical significance of 5% and the coefficient of influence is up to 0.122, that is, when the bank's LLP is forecasted to grow by 1 %, bad debt decreased by 0.122%. The outcomes were consistent with the authors' initial projections. Despite a reversal, Karimiyan et al. (2013)'s research is consistent with the majority of earlier investigations, including Dimitrios et al. (2012), Messai (2013), and Pham Xuan Quynh & Tran Duc Tuan (2019). According to ROA, the more inefficiently a bank manages its operations, the less profitable it is. Increased Credit Risk is frequently the outcome of banks with low rates of return having subpar abilities in credit rating, collateral appraisal, and dedication to monitoring borrowers. Because there are more uncollectible loans when banks increase poor loans, interest collection falls. Additionally, the credit risk provisioning level has 16 increased as a result of the decline in loan portfolio quality. In contrast, the credit risk tends to diminish for commercial banks with high profitability, good bad debt management, or good cost management. Loan loss provision (LLP) has the same effect on non-performing loan ratio (NPL) as a statistical significance level of 1% and an influencing factor of up to 0.564, which means that when the bank's LLP is forecasted to grow by 1%, NPL rise to 0.564%. LLP influences the bad debt ratio in the same way; as bad debts rise, so does provisioning. At a relevant level of 1%, non-interest income (NII) has the same impact as the nonperforming loan ratio (NPL). According to the study's findings, when NII climbed by 1%, NPL increased by 0.0169%. Rising NII raises NPL, contradicting the assumption that high NII relieves pressure on credit income, lowering credit risk. However, given the situation of Vietnamese commercial banks, which are under pressure to achieve high profits while their scale and credit growth are constrained by SBV regulations. Banks have attempted to increase the proportion of NII, but due to ineffective cost management, increasing NII leads to increased spending resulting in increased NPL. The LDR, ETA, NIR, and EXR variables have an impact on NPL and are the same as expected by the authors. However, according to the regression results, the statistical significance of these variables has not been found. 5.2 Macro factors Inflation rate is positively correlated with bad debt ratio. When the inflation rate in the economy increases, the State Bank implements a tight monetary policy to combat inflation, and the credit activities of commercial banks will also be affected. Specifically, lending interest rates increased, input costs of enterprises were pushed up, which reduced business efficiency of borrowing enterprises, thereby directly affecting their ability to repay loans to banks. row. In addition, tightening lending by banks will lead to the illiquidity of the economy, stagnant production and business activities, businesses misappropriating capital from each other, insolvency, many Enterprises, especially small and medium-sized enterprises, face the risk of bankruptcy, pushing the burden of bad debt to banks. GDP increased by 1%, bad debt ratio increased by 0.0584%. This can be explained that when the economy grows continuously, because of competition for profits, banks will become dependent and careless in reviewing loan applications, leading to reduced debt quality. and the bad debt ratio increased. In the study of Inekwe and Murumba (2013), the authors studied the banking system of Nigeria in the period 1995 - 2005 and concluded that the bad debt ratio is positively related to real GDP. 17 6. Recommendations _____________________________________________________________________ The results of the regression model have shown that the factors that affect credit risk at Vietnamese commercial banks include macroeconomic factors and bank internal factors, in which the factor has the strongest influence. to credit risk are provision for credit risk (LLP), previous year's Non-Performing LoansLoans(L.NPL) and GDP growth (GGDP). In addition, 5 other factors were also found to have an influence on credit risk and were statistically significant, namely exchange rate (EXR), non-interest income (NII) and size (SIZE), but because of the low level of influence of these factors on credit risk at Vietnamese commercial banks, it is suggested to suggest solutions to limit credit risk so the author will focus on solutions to affect 4 factors that have a strong influence on credit risk at Vietnamese commercial banks. The author suggests the following solutions: To SBV Credit risk provision (LLP) is found to have a positive impact on credit risk, that is, if provision is reduced, credit risk will also decrease. . In order to reduce provision for credit risks, it is necessary to increase credit quality. When credit quality increases, it will affect the bad debt ratio of the previous year (L.NPL) in a favorable direction because when the credit quality is good, it will not increase the bad debt ratio each year, so next year banks customers will not have to find a way to reduce the previous year's bad debt. Some solutions suggested by the author to increase credit quality are as follows: It is necessary to limit credit risks from the very beginning, to avoid cases due to lack of attention and lack of close supervision so that when credit risks arise (as in years 2011 2012), they will pay attention and find ways to deal with them. Management will take a lot of time, effort and may even encounter situations that cannot be handled. To do this, SBV needs to: - Complete the operational risk monitoring apparatus of commercial banks on the basis of forming an independent department that does not participate in the risk creation process, which has the function of risk management and supervision for commercial banks; identify and detect risks; analyze and assess risk levels on the basis of established criteria and criteria, and at the same time propose measures to prevent and minimize credit risks. - Build an online information system connecting the data of banks with the data of the state bank. Through this system, the State Bank can know which banks have abnormal signs, they will organize unexpected inspection and supervision and take timely action to intervene with that bank. If violations are detected, they must be strictly handled. Currently, the updating of information into the information system of the SBV is mostly 18 done by the banks sending reports, then the SBV will update the system. Manual updates like this are often slow and easy to falsify information, so it will be difficult for the SBVto detect problematic situations to take timely intervention actions. - Build an online credit scoring system for all customers of the whole Vietnamese commercial banking system. Accordingly, the State Bank will play a central role, when data is updated at a bank, it will also be updated immediately into the information system of the state bank. Currently, the credit rating of customers, although it is complied with the criteria of the SBV, but the implementation is done by each bank itself, there is no general update data system in the whole banking system. Therefore, this scoring is still subjective and has not had much impact on customers' sense of debt repayment. To Commercial Banks The cause of credit risk (i.e. poor credit quality) comes mainly from people. Therefore, the first solution proposed by the author to increase credit quality is related to human resources. Specifically, commercial banks need to have a solution for human resources, first of all, banks must develop and complete a recruitment regulation and strictly comply with this regulation, and before performing the operation, employees need to be trained in both professionalism and professional ethics, specifically: + Focused training to provide foundation knowledge. + On-the-job training: hands-on work instructions. + Organize periodic and irregular professional knowledge checks for each title. + Organize training courses on professional ethics for bank staff, especially for controlling, managerial and administrative positions. + To ensure compliance with regulations on professional ethics, besides communication, commercial banks need to stipulate and enforce sanctions (should be strict to have a deterrent effect) for violations related to ethics and professional ethics. - Develop a system of internal documents and dispatches to provide detailed instructions for each operation to ensure the correct, adequate and synchronous implementation of regulations of the State Bank and the Government in credit granting activities and also limit errors due to lack of synchronization, lack of information within the bank. When the SBV or the Government issues new regulations, directions or orientations, commercial banks need to organize communication and implementation guidance for the bank's personnel, ensure the regulations, direction or orientation of the SBV and Government is done right. - Gradually shift credit operations mainly conducted by humans to machines and technology to limit human-made errors, as before, credit application appraisal, preparation of credit documents, etc. Credit records, which are manually manipulated by 19 employees on the computer, now need to be edited on the application program, all data is updated, controlled from the beginning and performed and controlled on the program. The use of technology in credit operations also helps to limit negative and fraudulent actions in the credit granting process, so credit quality is more assured through transparency in the appraisal and approval process, and limits errors in the preparation of documents. The synchronous implementation of the above-proposed solutions will help credit activities of Vietnamese commercial banks to limit risks, on that basis, create a safe foundation for credit activities, even in the event of a crisis in the world economy and affecting the Vietnamese economy. In addition, by the end of 2021, the outstanding amount of bad debt has not been completely resolved. The prolongation of the time for the final settlement of this bad debt block hinders the operation and development of the banking system. Therefore, it is necessary to quickly solve this bad debt block. Some solutions that, according to the author, will help quickly resolve outstanding bad debts are: - In addition to the main tool to solve bad debts, which is VAMC, it is necessary to mobilize other resources in the society. Because the amount of bad debt outstanding is still large, VAMC’s capital is limited, so it is difficult to completely solve bad debt quickly. In order to mobilize the resources of society to solve bad debts, the author believes that it should expand the scale of the debt trading market by allowing qualified economic organizations to participate, especially foreign investors, as a potential channel. In addition, the size of debt trading companies also needs to be commensurate to be able to deal with the large bad debts of the whole Vietnamese banking system. - Establishing a debt trading floor: According to the author, the debt trading floor will be the place to introduce and provide the most complete and official information about debts to investors. Like the stock exchange, the debt trading floor is responsible for developing the trading infrastructure, setting standards for listing debt information, and managing and developing market-making intermediaries. Investment organization, building supervision mechanisms, and investor protection regulations. On the other hand, the establishment of an exchange will increase the transparency and publicity of the debt trading market. 20 APPENDIX 1: RESEARCH DATA SUMMARY TABLE (BANK INTERNAL VARIABLES) Bank
