This paper attempts to assess the demand and supply of liquidity in Islamic banks and to check the resilience of the industry to liquidity pressure. Firstly, it identifies the sources of short-term demand and supply of liquidity. Secondly, it assesses the historical performance of banks to manage liquidity. Thirdly, this paper predicts the short-term future performance and investigates the resiliency of the industry against any liquidity pressure by using ARIMA models and Bayesian technique. The paper finds that the industry has historically managed liquidity very well. Nevertheless, the resiliency against liquidity pressures is not strong enough because it does not perform well when irregular demand of liquidity or a liquidity run occur. As such, this paper suggests to Islamic banks that they intensify education of the public on Islamic banking principles, improve banking facilities, products and services, and optimize bank financing.
