Sukuk
Also known as: Islamic bond, Sharia-compliant certificate
Not a bond — a certificate of ownership in an asset that generates rent. Economically similar, legally very different, and the difference only shows up when something goes wrong.

1 · SnapshotThe one idea to remember
2 · BeginnerWhat is it, really?
Islamic finance prohibits riba — interest — so a conventional bond, which is a loan at interest, is not available. A sukuk delivers a similar economic result through a different legal structure.
Instead of lending money, the investor buys a share of an actual asset and receives the income that asset produces:
- A special purpose vehicle buys a building, an aircraft or a portfolio of assets using investors' money.
- The vehicle leases the asset back to the originator, which pays rent.
- The rent is distributed to certificate holders. At maturity the asset is repurchased and the principal returned.
The cash flows look like a bond's coupons and redemption. The legal claim does not: sukuk holders own an interest in property that produces rent, rather than holding a debt claim on a borrower.
3 · IntermediateHow it works in practice
The main structures
- Ijara (lease) — the classic. Assets leased back, rent distributed. The most transparent link between certificate and asset.
- Murabaha (cost-plus sale) — assets sold at a marked-up deferred price. Widely used but debt-like, and generally not tradeable at anything other than par in stricter interpretations.
- Wakala (agency) — an agent invests in a pool of compliant assets on investors' behalf and targets a return.
- Mudaraba / Musharaka (partnership) — genuine profit-and-loss sharing. Closest to the underlying principle, least common in practice, because investors want bond-like certainty.
What compliance requires
| Rule | Consequence for the structure |
|---|---|
| No interest (riba) | Returns must come from rent, profit or trade |
| No excessive uncertainty (gharar) | Terms must be fully specified up front |
| No prohibited sectors | Alcohol, gambling, conventional banking, tobacco excluded |
| Asset backing | A real asset must underlie the certificate |
Asset-backed versus asset-based — the distinction that matters
Most sukuk are asset-based: the assets provide the compliant form, but on default investors have recourse to the originator, ranking alongside its unsecured creditors. A minority are genuinely asset-backed, with a true sale and real recourse to the asset itself. The documents read similarly; the outcomes in a default do not.

Pricing: the same machinery, a different label
An asset-based sukuk is valued exactly like the issuer's conventional debt — discount the scheduled distributions on the issuer's credit curve. Where a conventional comparable exists, sukuk typically trade a few basis points inside it, reflecting a dedicated Islamic investor base with limited compliant alternatives. That spread is a demand-driven technical, not a credit judgement, and it compresses or vanishes when Gulf issuance is heavy.
The structural risks that have actually bitten
- Enforcement uncertainty. Restructurings in the Gulf have repeatedly turned on whether investors owned the assets or merely had a contractual claim to their proceeds — often resolved in local courts, under law and precedent unfamiliar to international creditors.
- Sharia risk. A structure approved by one scholarly board may be criticised by another, and standards have tightened over time. A 2008 ruling that many partnership-based sukuk did not meet profit-and-loss-sharing requirements reshaped the market's structure mix within a year.
- Liquidity. Sukuk are disproportionately held to maturity by Islamic banks needing compliant liquid assets. Secondary trading is thinner than size suggests, and the spread cost of exiting is correspondingly higher.
- Restructuring is genuinely harder. Standstills and coupon deferrals that are routine in conventional debt may conflict with the structure's compliance, narrowing the available options.
Why it is in a global atlas
The market runs to several hundred billion dollars a year in issuance, sits in mainstream emerging-market indices, and is bought by conventional investors who never think about compliance. It also functions as a clean case study in a general principle: the economic payoff and the legal claim are different objects, and only the second one matters after a default. The same lesson runs through credit-linked notes and securitisation.
