The study analyzed how different factors affect the profitability of conventional foreign exchange banks in Indonesia from 2011 to 2014. They looked at things like bad loans, interest rates, expenses, corporate governance, and more. The results showed that some factors, like operating expenses and loan-to-deposit ratio, had a negative impact on bank profits. On the other hand, factors like net interest margin and good corporate governance had a positive effect. Overall, these factors together can explain the profitability of these banks during the study period.
