LUONG QUYNH ANH ID No: 21071825 Intake 5 SUPERVISOR: DR. TRAN MANH HA Banking Academy of Vietnam September 2022 EXECUTIVE SUMMARY The financial system is mostly dominated by banks and banks play a vital influence in the economy of countries around the world. The financial crisis and worldwide economic recession that started at the end of 2007 in the US had a huge impact on the whole world, substantially hurting the business position of commercial banks.
As a result, many banks had to declare bankruptcy due to the pursuit of immediate profits without ensuring the operational safety of the banking system, which has raised alarm bells for the credit risk management mechanism. This dissertation used the fixed effect model and random effect model with 12-year data (from 2010 to 2021) from commercial banks of 09 countries in Southeast Asia evaluate impact of credit risk on banking performance. This dissertation contributes more empirical evidence and provides some useful information on the impact of credit risk on banking performance, thereby ensuring the science of policy recommendations. 1 ACKNOWLEDGEMENTS Prior to anything else, I would want to express my thanks to my supervisor, Dr.

Motivation Theoretical background Empirical studies related to the assessment of bank performance with the impact of the credit risk variable have been widely performed in different contexts over the past several decades. In commercial banks, credit operations carry the most risks. Credit risk occurs when borrowers fail to repay their loans to the bank when due, this affects the operation or even determines the existence or bankruptcy of the bank. In this sense, credit represents qualitative factors about a bank's financial strength (Duttweiler, 2011).
Credit risk is the first sign that a bank is in financial trouble. Credit risk not only threatens the safety of individual commercial banks, but also concerns the safety of the entire banking system (Eichberger and Summer, 2005). Currently, there have been many studies analyzing the relationship between credit risk and bank performance over the world. While some studies find a positive effect of credit risk on profitability of banks, others show a negative relationship between credit risk and profitability of commercial banks.
Regression results from the panel data model show that credit risk has a positive relationship with bank performance, showing that banks in Ghana are profitable despite taking on high credit risk. Boahene (2012) tested the relationship between credit risk and profitability at 06 commercial banks in Ghana from 2005 to 2009, in which return on equity (ROE) was used as the dependent variable. In Vietnam, a research by Huynh Thi Huong Thao (2018) used a data sample of 35 Vietnamese commercial banks in the period from 2008 to 2017 to study financial risk factors affecting the performance of commercial banks in Vietnam by DEA (Data Envelopment Analysis). The study 4 uses the ratio of bad debt to total outstanding loans, the ratio of provision for credit risk to total outstanding loans as independent variables of the model.
The results showed that the credit risk measurement variable has a positive relationship with the profitability of Vietnamese commercial banks. In addition to the above studies, the researches on evaluating the efficiency of banking operations are also interested by many authors such as: Nguyen Thanh Dat (2021); Alshatti (2015), Saeed, M. However, at present, there is no research on the impact of credit risk on banking operations in many countries in Southeast Asia. Therefore, research results need to be verified to improve reliability.
Practical background The financial system is largely dominated by banks (Diamond and Dybvig, 1983), banks play a significant part in the economics of countries across the world. The financial crisis and worldwide economic recession that started at the end of 2007 in the US had a great influence on the whole world, seriously harming the business standing of commercial banks. As a result, many banks had to declare bankruptcy due to the pursuit of immediate profits without ensuring the operational safety of the banking system, which has raised alarm bells for the risk management mechanism, especially the risk management mechanism, especially credit risk is underestimated (Moore, 2010). After the financial crisis, the Basel Committee on Banking Supervision (BCBS) published the Basel III accord to strengthen coordination, supervision and risk management in the banking industry.
Basel III offers numerous new ideas on capital, leverage and credit to enhance regulations on supervision and risk management. The financial crisis of 2007-2008, clearly underscored the 5 importance of credit risk and credit risk management for the operation of the financial market in general and the banking industry in particular (Bank for International Settlements, 2010; Bank for International Settlements, 2013). Banks in Southeast Asian countries, although not severely affected by this crisis, are banks safe and efficient or lucky thanks to their low level of integration into the market international finance? For Vietnam, after the financial crisis has had certain impacts, the operating environment and institutions of the banking system have made remarkable changes in terms of internal governance, organizational structure, application technology and the development of modern banking services. However, not outside of the general rule, economic instability has caused many significant losses to the banking system in all aspects.
Since then, in turn, the instability of the banking system affects the economy and causes significant consequences (Nguyen Cong Tam and Nguyen Minh Ha, 2012). In the integration trend, the requirement to manage credit risks and ensure the efficiency of banking performance is more necessary than ever. The practical context of Southeast Asian countries shows that Vietnam is one of the countries with low per capita income in the research countries of Southeast Asia, but there are too many banks. , but lacks a pillar bank that can compete with other countries in the region (Nguyen Cong Tam and Nguyen Minh Ha, 2012).
Therefore, studying the impact of credit risk on the bank performance the case study of Southeast Asian countries in the period 2010 - 2021 also contributes to verifying the impact of credit risk to the efficiency of banking performance in Vietnam. Derived from the theoretical context and the practical context, in order to fill the research gaps; therefore, the author has chosen the topic "Impact of credit risk on commercial bank’s performance: a case study of Southeast Asian countries" for the period 2010-2021. In addition, the study combines and compares the results of case studies of Southeast Asian countries and 6 Vietnam to propose policy suggestions for Vietnam. This dissertation contributes more empirical evidence and provides some useful information on the impact of credit risk on banking performance, thereby ensuring the science of policy recommendations.
Research objectives and questions General objective The main research objective of the thesis is to identify the factors affecting credit risk and analyze the impact of credit risk on the bank performance, case study of Vietnam countries in the period 2011-2021. Specific goals: On that basis, the specific objectives of the study are determined to be: Analysis of the influence of credit risk on performance of commercial banks, case studies of Southeast Asian nations and Vietnam. Suggest policies on credit risk management to perform banking in Vietnam more effective. Research question The study focuses on answering the following questions: Is there any difference in the results of research on factors affecting bank credit risk in Vietnam and other Southeast Asian countries? How does credit risk affect banking performance in Southeast Asian countries? What are the policy recommendations related to risk management and ensuring the efficiency of banking performance in Vietnam? 7 3.
Object and scope of research Object subject: Impact of credit risk and banking performance, a case study of Southeast Asian countries. Research scope: Not only focusing on a few individual countries as in previous studies, the research scope of the topic is extended to analyze 9 Southeast Asian countries (Cambodia, Indonesia, Lao, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam) in the study period 2010 - 2021. The source of data used in the research is from the BankFocus and Osiris data sources of banks in the world, so it should ensure the uniformity and higher reliability to better reflect the assessment of the impact of credit risk on banking performance. This is a period of accelerating the process of international economic integration of Southeast Asia, including Vietnam.
