The purpose of this paper is to empirically assess the impact of the principle of profit- and loss-sharing (PLS) on the exposure to liquidity risk of Islamic banks in Gulf Corporation Council (GCC) countries. The Islamic bank activity is distinguished by a PLS principle, which is likely to involve specificities in the bank liquidity issue.,This paper investigates the determinants of Islamic bank liquidity over the period 2005–2016 using a panel of 23 Islamic banks in GCC. The system of generalized method of moment estimators is applied.,The findings reveal that while profit-sharing investment accounts (PSIAs) are inversely proportional to Islamic bank liquidity, the PLS investment does not seem to act as a determinant of the bank liquidity. The fact that PSIAs are globally short-run accounts, but finance long-run projects leads to a substantial maturity mismatches, which limits the availability of liquidity buffer and exacerbates the bank’s exposure to liquidity risk. Moreover, capital adequacy ratio has significant and positive association with bank liquidity, as a strong capital ratio helps to strengthen the liquidity control. However, return on assets has a negative significant impact on bank liquidity. For instance, if the bank holds more cash, it deprives itself from placing funds and earning returns, which causes its profitability to decline.,This paper gives further insights to better improve the liquidity risk management in a context of scarcity of Shariah-compliant instruments. Islamic bank needs to determine the PLS purpose and goals to be consistent with the “bank’s financing policy” and convince its depositors to use their deposits for medium and long-run investments.,Unlike previous empirical research, this investigation tries to better grasp the Islamic bank liquidity issue by focusing on the PLS impact on liquidity risk. It aims to fill in the gap in the empirical literature on this topic.

损益分享对海湾合作委员会国家伊斯兰银行流动性的影响

本文的目的是从经验上评估盈亏共享原则（PLS）对海湾公司理事会（GCC）国家的伊斯兰银行的流动性风险敞口的影响。回教银行的活动以PLS原则为特征，该原则很可能涉及银行流动性问题。本文使用GCC的23家回教银行组成的小组，调查了2005-2016年间回教银行流动性的决定因素。结果表明，虽然利润共享投资账户（PSIA）与伊斯兰银行的流动性成反比，但PLS投资似乎并不能决定银行的流动性。PSIA是全球短期帐户，但是长期融资项目会导致严重的期限错配，从而限制了流动性缓冲的可用性，并加剧了银行面临的流动性风险。此外，资本充足率与银行流动性具有显着正相关关系，因为强大的资本比率有助于加强流动性控制。但是，资产收益率对银行的流动性具有负面影响。例如，如果银行持有更多现金，就会丧失资金投入和收益回报的能力，这会导致其利润率下降。本文提供了进一步的见解，可以在缺乏符合伊斯兰教义的工具的情况下更好地改善流动性风险管理。伊斯兰银行需要确定PLS的目的和目标，使其与“银行的融资政策”相一致，并说服其储户将其存款用于中长期投资。与以往的实证研究不同，本调查试图更好地把握伊斯兰银行。通过关注PLS对流动性风险的影响来解决银行流动性问题。它旨在填补有关该主题的经验文献中的空白。
