The approval requirement in Rule LR-1.2.23 only has to be made once, prior to the licensee starting to undertake such transactions. Its purpose is to allow BMA to monitor the initiation of such business by Islamic wholesale bank licensees, and to check that adequate systems and controls have been in place, so that such transactions are likely to be well managed. In addition, it is to allow, where relevant, for the necessary arrangements to be made to ensure that Islamic wholesale bank licensees comply with the BMA's reserve requirements (which apply to deposit liabilities denominated in Bahraini Dinars — see LR-2.5.10).
