Islamic bank licensees must establish the maximum amounts of cumulative liquidity mismatches which they consider acceptable (subject to the requirements of Module LM) and manageable for different time bands, as a percentage of total funds available. Assets must be clearly segregated according to sources of funds, and Islamic bank licensees must monitor their liquidity exposures separately according to the nature and mix of their fund providers — current account holder and unrestricted IAH, which can be expected to vary substantially. The effects of liquidity shortages may vary according to the fund providers' liquidity preferences; hence, separate limits on liquidity mismatches must be set up accordingly. These limits must be regularly reviewed, taking into account the Islamic bank licensee's liquidity situation, economic climate and market conditions.
