This empirical study focuses on the profitability of Islamic banks in Bangladesh. The researchers selected six randomly chosen Islamic banks and utilized commonly suggested measures of profitability, including Return on Asset (ROA), Return on Equity (ROE), and Return on Deposit (ROD). These measures are widely used by the Bangladesh Bank to evaluate bank performance. Additionally, the study examined the relationship between ROA and other factors such as Asset Utilization (AU) and Operational Efficiency (OE). The results showed that EXIM Bank Limited performed exceptionally well in terms of all profitability measures, including ROA, ROE, and ROD. Interestingly, even though Islami Bank Bangladesh Limited had the largest average asset size among the six Islamic banks, its performance was not as strong. Furthermore, a regression analysis was conducted to determine the association between ROD and ROA. The results indicated a significant association between these variables. However, no significant associations were found between ROD and operational efficiency or asset utilization. An analysis of variance was also conducted to assess the overall significance of the regression model. The coefficient of determination (r-square) revealed that 99.8% of the variation in ROA could be explained by the regression line. Moreover, the calculated F-ratio value exceeded the critical value at a 0.05 level of significance indicating that the regression model as a whole was statistically significant. In conclusion, this study provides valuable insights into understanding factors influencing bank profitability in an Islamic banking context using widely accepted measures such as ROA and ROD. It highlights EXIM Bank Limited's exceptional performance while emphasizing that average asset size does not necessarily correlate with profitability.

Abstract: This empirical study is conducted on randomly selected six Islamic banks of Bangladesh. This study utilizes widely used Measures of banks profitability which are Return on Asset (ROA), Return on Equity (ROE) and Return on Deposit (ROD) and these are also commonly suggested tools by Bangladesh Bank to evaluate banks performance. In addition, this study examined the relationship of ROA with Asset Utilization (AU), Operational Efficiency (OE)and ROD. The result reveals that EXIM Bank Limited is performing very good in terms of all profitability measures ROA, ROE and ROD even though average asset size of Islami Bank Bangladesh Limited is found to be largest among all six Islamic Banks. The result of regression found the explanatory variable ROD is significantly associated with ROA but failed to establish any significant association with operational efficiency and asset utilization.
