This is because the banking sector controls 77% of financial sector assets. This study tests the effect of bank performance on stability and risk-taking behavior by analyzes the effect of ownership structure of 31 commercial banks with the largest total assets in Indonesia. By using the two-step generalized method of moment as an estimator method to solve the endogeneity problem, this study found that bank performance has a positive and significant effect on bank stability and has a significant negative effect on risk-taking behavior. Concentrated ownership structure also has a positive and significant effect on the relationship between bank performance and stability, and has a negative and significant effect on risk-taking behavior.
