Sukuk are the closest thing a compliant portfolio has to a bond. They pay a regular income, they are issued by governments and companies, and on a statement they sit where fixed income would. What separates them is what the holder owns, and that difference is why sukuk are permissible when bonds are not.

Ownership, not a loan

A conventional bond is a loan. The investor lends money and the issuer pays interest on it, which is riba and is not permitted. A sukuk certificate instead represents a share in something real: a building, equipment, a lease, or a defined business venture. The income comes from what that asset earns, as rent or profit, rather than from lending money at interest.

The common structures

Most issuance uses a handful of contracts, and the contract decides how the return is generated.

  • Ijara. The issuer sells an asset into the structure and leases it back. Holders receive the rent.
  • Murabaha. A cost-plus sale. Once the sale completes the certificates represent a debt, so they are usually held to maturity rather than traded.
  • Mudaraba and musharaka. Partnerships in which holders share the profit of a venture, and its losses.
  • Wakala. An agent manages a pool of assets on the holders’ behalf. It has become one of the most widely used structures.

What ownership does not change

It is tempting to conclude that owning an asset makes a sukuk safer than a bond. Usually it does not. Most sukuk are asset-based rather than asset-backed: holders have a beneficial interest in the asset, but if the issuer defaults, their practical claim is on the issuer, much as an unsecured bondholder’s would be. Credit quality still has to be judged issuer by issuer.

Prices also still move with interest rates. When market yields rise, existing sukuk paying a fixed return become less attractive and their prices fall, as bond prices do. Secondary markets are thinner than conventional bond markets too, which matters if you may need to sell before maturity.

Where sukuk fit

Their job in a portfolio is the one fixed income does elsewhere: steadier income, lower volatility than equities, and a return stream that does not depend on the stock market alone. That is why they come up whenever a client holds more cash than their plans require, a cost we covered in Why Cash Drag Costs a Halal Portfolio More.
