Guide to the capital preservation debate in Wakalah Sukuk structures

In-Depth Analysis

One of the most intensely debated aspects of Wakalah Sukuk is the question of capital preservation — specifically, whether the issuer or the Wakeel can provide an undertaking to repurchase the underlying assets at their face value at maturity, effectively guaranteeing the return of the Sukukholders' principal. This debate goes to the heart of Shariah compliance in the Sukuk market and has generated significant scholarly discussion, regulatory guidance, and market controversy. In a pure Wakalah structure, the Sukukholders bear the full investment risk. If the underlying assets decline in value, the Sukukholders absorb the loss. If the assets appreciate, the Sukukholders enjoy the gain. There is no guarantee of capital preservation because the Wakeel is merely an agent, not a guarantor. However, in practice, many Wakalah Sukuk include a purchase undertaking (Wa'd) by the originator or a related party to purchase the underlying assets at maturity at their face value or at a predetermined price. This purchase undertaking effectively ensures that the Sukukholders receive their capital back, provided the originator is solvent and able to fulfill the undertaking. Shariah scholars have taken varying positions on the permissibility of purchase undertakings in Wakalah Sukuk. The AAOIFI Shariah Board, in its landmark 2008 resolution on Sukuk, addressed this issue directly. The resolution stated that the manager of Sukuk (whether as Mudarib or Wakeel) cannot guarantee the Sukuk capital or the return — however, a third party (not the Wakeel itself) may provide a guarantee or purchase undertaking without violating Shariah principles. Some scholars have interpreted this to mean that the originator, in a capacity separate from its role as Wakeel, can provide the purchase undertaking. Others argue that when the originator is also the Wakeel, any purchase undertaking is effectively a self-guarantee and is therefore impermissible. The practical implications of this debate are enormous. If purchase undertakings are not permissible, Wakalah Sukuk become full risk-participation instruments — more akin to equity than debt. This would significantly reduce their attractiveness to conventional fixed-income investors who require capital preservation for regulatory and investment mandate reasons. Conversely, if purchase undertakings are broadly permitted, the difference between Wakalah Sukuk and conventional bonds becomes more difficult to articulate, potentially undermining the credibility of the Islamic finance industry. The market has arrived at a pragmatic compromise. Most Wakalah Sukuk now include a purchase undertaking by the originator, but the Shariah opinion (Fatwa) accompanying the issuance typically emphasizes that the undertaking is a unilateral promise (Wa'd) that is separate from and not part of the Wakalah contract itself. The legal documentation is structured to maintain a clear separation between the agency agreement and the purchase undertaking, and Shariah reviewers examine this separation carefully during the issuance process.
