Competitive conditions and market power of Islamic and conventional commercial banks

The expansion of the Islamic banking industry seems to accentuate the banking competition in MENA and Southeast Asia where conventional and Islamic banks coexist. In this context, the research aims\ to examine the competitive conditions and the market power of the conventional and Islamic banks during the period 2004-2009 in MENA and Southeast Asia region.

The authors use 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 set of measures of the competition and market power. The first measure is a set of concentration ratios (C3, C5) and Herfindahl-Hirschman index (HHI). The second measures are the Panzar and Ross H statistic and the Lerner index based on econometric estimations with the aim of evaluating the structure of market and measuring its power in terms of price setting.

The results indicate that under the HHI index, both markets are low concentrated, while according to the concentration ratios, the Islamic market is considered as moderately concentrated. The estimations results, through the H-PR-statistic of Panzar and Ross related to degree of competition and the Lerner index of market power, indicate that both markets are characterized by a monopolistic competition and the Islamic banking expressed a high degree of market power.

The research focuses exclusively on the countries where the data are available and excludes the other countries where competition and market power might have different forms.

In a competitive environment, each bank is required to analyze the structure of its market and competitive conditions, in order to develop a business strategy and effective action plans. In the context of the multiplication of the Islamic banks in the MENA and Southeast Asia, the enhancement of Islamic bank competitiveness by offering new products is determinant for their success.

To the best of the authors' knowledge few studies have examined this subject in a comparative analysis between the Islamic and conventional banks. So the authors contribute to the literature on Islamic banking by considering a sample of Islamic and conventional banks operating in the same countries in order to examine the existence or not of difference between them.
