An Islamic bank licensee may also place liquid funds with a central bank or another Islamic bank licensee on a short-term Mudarabah basis in order to obtain a return on those funds. Such placements serve as an interbank market transaction with maturities ranging from overnight up to three months, but the funds may be withdrawn on demand before the maturity date, in which case the return is calculated proportionately on the basis of duration and amount. Although from a juristic point of view the amounts so placed do not constitute debts, since (in the absence of misconduct or negligence) Mudarabah capital does not constitute a liability for the Mudarib, in practice the operation of this interbank market requires that the Mudarib should effectively treat them as liabilities. Hence, an Islamic bank licensee placing funds on this basis may treat them as cash equivalents and, for risk-weighting purposes, apply the RW applicable to the Mudarib as counterparty.
