This study attempts to explore the relationship between the financial performance indicators of Bangladeshi listed banks and the CSR reporting checklist. In order to generate the CSR checklist in compliance with guidelines given by the Bangladesh Bank's (BB) Sustainable Finance Department, 30 annual reports (2019 to 2023) of listed private commercial banks were studied using content analysis. The majority of the sample banks are aware of reporting their CSR activity, based on this analysis. The empirical result of the survey on 130 employees of the sample banks indicates that there is a favorable correlation between CSR reporting and financial performance indicators such as Return on Assets (ROA), Return on Equity (ROE), Return on Sales (ROS), and Net Profit Margin (NPM). The findings of the study can be useful to the concerned stakeholders of banks to boost CSR activities toward the long-term sustainability in this competitive business world.
