Among the available liquidity management instruments in Islamic banking, only sukuk of a particular type meet the requirements of HQLA (in principle) as defined by the Basel Committee and adapted for Islamic finance by the IFSB (Islamic Financial Services Board) (IFSB, 2017). Candidates for HQLA are only international sukuk, i.e. sukuk that are issued in an international currency, sukuk that are also publicly listed, and sukuk that are traded not only locally but also internationally. Sovereigns and international institutions such as the IDB (Islamic Development Bank) have issued almost all sukuk of this caliber. In this PhD thesis, the research will make empirically informed qualitative projections on the outlook for HQL (high quality liquid) sukuk to constitute the LAB (liquid asset buffer) portfolio for an Islamic megabank MDB (multilateral development bank) in the context of a rising global interest rate environment, falling oil prices, and a challenging global environment. Further qualitative projections about the prospects for the sukuk market are made based on a few case studies that encapsulate some of the critical limitation facing the sukuk market.
