Guide to aAOIFI Shariah Standard No 17: The definitive framework for Sukuk

In-Depth Analysis

The AAOIFI Shariah Standard No 17 is the most authoritative and comprehensive framework governing Sukuk structures globally. Originally issued in 2003 and subsequently revised, this standard provides the definitional, structural, and compliance parameters for Sukuk issuances. Any serious study of Sukuk must begin with an understanding of this standard, as it forms the basis upon which Shariah scholars, structurers, and regulators evaluate Sukuk transactions. Standard No 17 identifies 14 types of Sukuk, each based on a recognized Shariah contract. These are: (1) Ijarah Sukuk, (2) Salam Sukuk, (3) Istisna Sukuk, (4) Murabahah Sukuk, (5) Musharakah Sukuk, (6) Mudarabah Sukuk, (7) Wakalah Sukuk, (8) Muzara'ah Sukuk (agricultural sharecropping), (9) Musaqah Sukuk (irrigation partnership), (10) Mugharasah Sukuk (agricultural planting), (11) Sukuk of ownership in leased assets, (12) Sukuk of ownership in usufruct of existing assets, (13) Sukuk of ownership in usufruct of described future assets, and (14) Sukuk of ownership in services from an existing party. The standard establishes several universal requirements that apply across all Sukuk types. First, the underlying assets must be identified and the Sukuk holders must have true ownership interest — not merely a contractual claim for repayment. Second, the Sukuk must not guarantee the return of principal or a fixed return, as this would convert the instrument into a de facto interest-bearing loan. Third, the trading of Sukuk on the secondary market is only permissible when the underlying portfolio is predominantly composed of tangible assets or usufructs, rather than receivables or monetary claims. A critical revision to Standard No 17 came in 2008, when AAOIFI issued a landmark statement clarifying that many Sukuk structures in the market had deviated from Shariah requirements. Specifically, AAOIFI criticized the widespread use of purchase undertakings at face value in equity-based Sukuk (Musharakah and Mudarabah), which effectively guaranteed principal return and converted the instrument from an equity-like structure to a debt-like one. This intervention reshaped the Sukuk market and led to more careful structuring of new issuances. The standard also addresses the role of the Special Purpose Vehicle (SPV) in Sukuk issuances, the conditions for dissolution of the Sukuk trust, and the rights and obligations of the obligor, trustee, and certificate holders. These provisions ensure that the legal structure supports genuine Shariah compliance rather than merely superficial adherence.
