One of the major sectors of Bangladesh economy is the Banking Industry. The financial performance of banks plays a crucial role to any country’s GDP and determines the growth of a nation. Considering the importance of the fact, this study has undergone a comparative analysis on the financial performance of 1st, 2nd and 3rd generation banks of Bangladesh from 2008 to 2019. A total of 21 banks have been selected randomly to support the analysis of seven banks from each generation. To assess the financial performance of these banks, three measures are used, i.e. Profitability ratios, liquidity ratios and capital adequacy ratio. This research also examines the mean differences on profitability ratios among the three generation banks by analysis of variance (ANOVA) test. The result of the hypothesis suggests that there are no major variations in profitability ratios among the three-generation banks. All the three generation banks exhibit a standard positive result in the area of profitability ratios, liquidity ratios and capital adequacy ratio, thus reflecting the financial soundness of all the three generation banks.
