This research is aimed to analyze the effect of foreign bank entry on Indonesian domestic banks performance by using aggregate and disaggregated measures in 2004-2012. By applying fixed effect estimators, this research presents that foreign bank presence has a negative effect on net interest margin. However, this research found that foreign bank presence has positive effects on noninterest income and overhead cost. These findings suggest that foreign banks play an important role to encourage domestic banks to operate more efficient. However, an increased foreign bank presence forces domestic banks to spend more.
