Purpose The purpose of this paper is to examine the competitive conditions and market power of Islamic banks in Indonesia for the period of 2006-2013. Design/methodology/approach Using samples of 27 Islamic banks, the study uses a variety of structural and non-structural measures related to the traditional approach and the new empirical approach of the industrial organization. The methodology is based on a set of measures of the competition and market power. The first measures, concentration ratios and Herfindahl–Hirschman index, are to determine the competitiveness level, while the second measures of Panzar–Rosse H-statistic and Lerner index are to examine the market power of Islamic banks in Indonesia. Findings The finding of this study has confirmed the situation of Islamic banking industry in Indonesia which is operated in a higher degree of market power which leads to a less competitive market. Islamic banks earn their revenues under monopolistic competition over the tested period. This study has also found a negative but insignificant relationship between concentration and competition which shows that in the past few years, the market power for leading firms in Indonesia Islamic banking industry has reduced. Practical implications The paper is a very useful source of information that may provide relevant guidelines in guiding the future development of competition of Islamic Banking industry.
