The Impact of the Islamic Financing Instruments (Participatory & Commutative) On the Profitability of Iranian Private Banks

More than three decades have passed from the non–usury Banking Law enforcement in the country. The banking system has faced some challenges during this period. Using asymmetric tabular data, this paper seeks to study the impact of Islamic participatory and commutative financial instruments on the profitability of sixteen private banks in the years that they used the contracts. The share of different contracts from the private banking facilities on the asset return rate (ROA), as an indicator of the profitability of the banks, has been processed in this study. Findings show that, cooperative contracts ("Mudaraba" Profit and Loss Sharing and Civil partnership) directly has a meaningful relationship with the profitability of banks, whereas, Commutative contracts do not have a significant relationship with profitability of banks (return on assets index). Meanwhile, the coefficients of virtual variables, which were modeled to measure the impact of specific circumstances in the years 2010-2013, were meaningless. Finding indicates that, special conditions of the four aforementioned years did not impact on the outcome of the models.
