Istisna Sukuk explained: Construction and manufacturing project certificates

In-Depth Analysis

Istisna Sukuk are based on the Istisna (manufacturing/construction) contract, which allows a buyer to commission the construction or manufacture of a specified item to be delivered at a future date with payment made in instalments during the construction period. In the Sukuk context, this structure is used to finance large infrastructure and construction projects in a Shariah-compliant manner. In a typical Istisna Sukuk structure, the SPV uses the Sukuk proceeds to enter into an Istisna contract with the originator, commissioning the construction of a specified asset (such as a building, road, bridge, or industrial facility) according to agreed specifications, timeline, and price. The SPV simultaneously enters into a parallel Istisna contract with a contractor who will actually undertake the construction. The SPV's profit is derived from the margin between what it pays the contractor and what it receives from the originator. Once construction is complete, the asset may be delivered to the originator (with the Sukuk returns coming from the Istisna profit margin), or the completed asset may be leased back to the originator under an Ijarah arrangement, converting the Sukuk into an Ijarah Sukuk for the remaining tenor. This Istisna-Ijarah combination is one of the most common structures for infrastructure Sukuk, as it provides a clear return mechanism for the post-construction period. Istisna Sukuk have been particularly useful for financing large-scale infrastructure projects in the GCC, Malaysia, and Turkey. Notable examples include the financing of airports, highways, power plants, and social housing developments. The structure is well-suited to project finance because the construction contract naturally defines the use of proceeds, the timeline, and the deliverables. The tradability of Istisna Sukuk during the construction phase is subject to the same rules as other debt-based Sukuk — because the underlying is a manufacturing/construction receivable, trading at discount/premium is restricted. However, once the asset is completed and the Sukuk transitions to an Ijarah phase, tradability becomes unrestricted (as the underlying is now a tangible asset generating rental income). A unique risk in Istisna Sukuk is construction risk — the risk that the project is not completed on time, within budget, or to specification. This risk is typically mitigated through parallel Istisna contracts with experienced contractors, construction insurance, and performance bonds. For investors, the construction phase represents a higher-risk period, with returns becoming more predictable once the project is completed and begins generating income.
