In the context of the fact that the structure of the Vietnamese banking market has undergone many fluctuations, which has had an impact on banking activities, and the fact that many related studies have been carried out, but the answer is still limited and inconsistent, it is necessary to study the impact of the market structure on banking operations in Vietnam. The paper comprehensively examines the impact of market structure on various aspects of bank performance in Vietnam. The study uses three measures of the structure of the banking industry, namely, the total market share of the largest banks, the squared market share of all banks according to the Herfindahl-Hirshchman index, and the Lerner index on market power (inverse bank competition), to ensure the results are not dependent on any specific measure. The paper applies the two-step system generalized method of moments estimator to conduct regression analysis for a sample of 30 banks from 2007 to 2021. All obtained estimates generally show positive effects on bank performance due to greater market power and higher banking concentration. Concretely, more market power and greater concentration improve bank asset quality, management efficiency, bank profitability, and lending capacity. Overall, the findings of this paper all support the bright side of less competition and more concentration, which is essential to derive policy implications related to supervising competitive environments and stimulating consolidated financial systems.

Banks and Bank Systems Volume 15, 2020 Issue #1 pp. 85-97 Views: 1232 Downloads: 414 TO CITE АНОТАЦІЯThe purpose of this article is to evaluate the financial soundness of commercial banks listed on the Palestine Exchange using the CAMEL rating system. A content analysis, composite rating, and a one sample t-test are applied to a sample of six local banks operating in Palestine. Secondary data were obtained from the financial statements of the banks for the period of 2007–2017 in order to conduct the research and evaluate their financial performance. The empirical test has shown that Palestinian banks adhere to the Basel Committee standards in terms of capital adequacy and that they display stability in terms of profitability and liquidity. However, the paper concludes that the operational efficiency of the banks being evaluated is “fairly managed”. Finally, the findings indicate significant differences amongst Palestinian banks in terms of performance, assessed using the CAMEL rating system. This paper suggests that the listed Palestinian banks should focus on long-term investments rather than short-term ones, and monitor their risk management practices to increase their profits and move towards sustainability and growth.

Banks and Bank Systems Volume 18, 2023 Issue #2 pp. 113-126 Views: 1009 Downloads: 459 TO CITE АНОТАЦІЯRisks inherent in banking businesses should be managed to prevent financial losses to the sector’s stakeholders and negative externalities to the global economy. To this end, this study examines the effect of risk management on the performance of deposit money banks in Nigeria. A sample of eight (8) deposit money banks with international authorization are purposively selected out of 12 deposit money banks due to data availability. Panel data analysis techniques were adopted to analyze the secondary data that were obtained from the annual reports of banks. Findings based on the disaggregated model results reveal that both liquidity and capital risk variables exert a negative but insignificant effect on performance. However, credit risk drives performance of the internationally authorized banks positively and significantly. Furthermore, Management quality (MQ) is the only control variable that has a significant influence on the performance of the selected deposit money banks. The study concludes that credit risk and management quality significantly and positively drive performance among the financial entities.
