Nine hundred billion dollars. That’s the global sukuk outstanding as of 2024, per the International Islamic Financial Market (IIFM) — with annual new issuance reaching US$205–230 billion in 2024, up significantly year-on-year. It includes sovereign debt from Saudi Arabia, corporate bonds from Emaar Properties, and a retail investment programme in Indonesia that has attracted more than 6 million individual investors. It is one of the most systematically underreported asset classes in global financial media.

The reason is embarrassingly simple: most Western financial analysts don’t understand the structure. So they don’t cover it. That gap between market size and media coverage is exactly where the opportunity sits.

Islamic finance prohibits riba — interest, in the sense of a fixed guaranteed return on money lent. This is not a technicality. It is a foundational principle that shapes the entire architecture of Islamic capital markets. A conventional bond works like this: issuer borrows money, promises to pay interest at regular intervals, returns the principal at maturity. The return to the investor is predetermined. The issuer bears all operational risk; the investor is protected by the interest contract.

A sukuk cannot work that way. The return to a sukuk investor must be derived from an underlying asset, not from interest on a loan. The most common structure — Ijara sukuk, which represents the majority of global issuance — works like this: the issuer creates a special purpose vehicle (SPV). The SPV “purchases” an asset from the originating entity — a building, a piece of infrastructure, a pool of receivables — at an agreed price. The SPV issues sukuk certificates to investors representing ownership shares in the SPV. The originating entity then “leases” the asset back from the SPV, making regular lease payments. Those lease payments flow through to sukuk holders as the investment return. At maturity, the originating entity buys the asset back at the original purchase price, and the SPV returns principal to investors.

The economic outcome for the investor is similar to a bond: regular income payments and return of principal at maturity. But the legal structure is a sale-and-leaseback, not a loan. The return is rental income, not interest. That distinction — which sounds like theological accounting — is what makes the instrument compliant with Islamic law and accessible to the world’s 1.9 billion Muslims, of whom an estimated 800 million are in the investable income bracket.

Malaysia dominates global sukuk issuance at over 60% of total global volume. This is not coincidental. Malaysia established its Islamic capital market regulatory framework in the 1990s, decades before any other jurisdiction. Bank Negara Malaysia (BNM) and the Securities Commission Malaysia built an entire ecosystem — Shariah advisory boards, standardised documentation, the Bursa Malaysia Islamic Market, and critically, Bursa Suq Al-Sila’ (BSAS), the world’s leading commodity murabaha trading platform that provides the liquidity infrastructure for much of global Islamic interbank funding.

When HSBC or Standard Chartered wants to issue a sukuk for a GCC client, the transaction documentation is often drafted using Malaysian templates. When a Gulf sovereign needs to structure a global sukuk, the law firms they hire were often trained in Kuala Lumpur’s Islamic finance ecosystem. Malaysia’s 30-year head start created standards that the rest of the market adopted.

Saudi Arabia is the second-largest issuer. The Saudi government has issued multiple tranches of sovereign sukuk since 2016, including a $5B Green Sukuk in 2021 — one of the largest green sukuk issuances globally. Saudi Aramco has issued corporate sukuk. Vision 2030 infrastructure projects are increasingly funded through sukuk rather than conventional bonds, partly for domestic Islamic finance development reasons and partly because Gulf sovereign wealth fund investors prefer Shariah-compliant instruments.

Indonesia has built the world’s largest retail sukuk programme. The State Sukuk (SR series) and Project-Based Sukuk (PBS series) are sold directly to Indonesian retail investors through online platforms and bank networks. By 2024, over 6 million individual Indonesians had purchased government sukuk through the retail programme — making it the most democratised Islamic debt product in the world. Minimum investment: IDR 1 million (approximately $62). The government uses the proceeds to fund specific national infrastructure and development projects, giving retail investors a direct ownership stake in government assets.

Ijara (lease-based): The most common structure, described above. Used for sovereign sukuk, real estate sukuk, and infrastructure sukuk where there is a tangible asset to underpin the SPV. Saudi sovereign sukuk, Malaysian sovereign sukuk, most GCC corporate sukuk use Ijara structures.

Murabaha (cost-plus sale): The SPV purchases a commodity on behalf of the issuer and sells it at a pre-agreed price inclusive of profit margin, payable in instalments. Used extensively in short-term Islamic liquidity instruments and trade finance. Bursa Suq Al-Sila’ facilitates the commodity leg of most global murabaha transactions.

Musharaka (partnership): Investors and the issuer form a joint venture. Returns are based on profit-sharing from the underlying business. Risk profile is higher — losses are shared. Less common for sovereign issuances; used in project finance structures and private equity-adjacent Islamic instruments.

Wakala (agency): The SPV appoints the originating entity as investment agent to manage a pool of assets and generate returns. Common in insurance-adjacent Islamic products (takaful) and in sukuk backed by diversified asset pools rather than single assets.

The type of structure matters for investor risk assessment. An Ijara sukuk backed by a Saudi government building has the credit risk of the Saudi government — effectively sovereign risk. A Musharaka sukuk for a real estate development has the credit risk of that specific project. Retail investors accessing sukuk through ETFs don’t need to assess individual structures, but institutional and private banking clients do.

Sukuk returns are broadly comparable to conventional bonds of similar credit quality and duration. A 5-year Malaysian government sukuk (AAA-rated domestic) yields approximately 3.5–4.2% annually (2024–2025 range). A Saudi sovereign sukuk (similarly high-grade) yields approximately 4.5–5.5%. Indonesian government sukuk (investment grade, BBB-) yields approximately 6–7% for the 5-year benchmark. These are not exceptional returns relative to their risk profiles — they are competitive with conventional government bonds from the same sovereign issuers.

Corporate sukuk commands a yield premium over sovereign sukuk from the same jurisdiction, as expected. Emaar Properties sukuk (Dubai-based real estate developer, investment grade) has historically traded at 100–150 basis points over UAE sovereign sukuk. GCC banking sector sukuk — Abu Dhabi Islamic Bank, Dubai Islamic Bank, Al Rajhi Bank — typically trade 50–80 basis points over sovereign benchmarks.

Liquidity is the honest challenge. The sukuk secondary market is thinner than the equivalent conventional bond market for most issuers. Large sovereign sukuk from Malaysia, Saudi Arabia, and Indonesia trade with reasonable liquidity. Mid-market corporate sukuk can have bid-ask spreads of 50+ basis points and may require days to sell at fair value in large sizes. Private banking clients at DBS, CIMB Islamic, or Maybank Islamic who access sukuk through structured products or managed accounts benefit from aggregated liquidity that individual retail investors cannot replicate.

Direct sukuk investment at the institutional level typically requires a minimum of $200,000 USD per instrument, routed through private banks or licensed bond dealers. This is the HNWI and family office entry point. For this segment, SGX-listed sukuk and OTC traded GCC sukuk are accessible through DBS, Standard Chartered Private Bank, CIMB, or dedicated Islamic banks.

For retail and self-directed investors, the access pathway is more constrained. There is no widely available global sukuk ETF listed on major exchanges that offers clean total return exposure to the sukuk market with good liquidity. The iShares MSCI World Islamic ETF (ISWD) covers Shariah-compliant equities, not sukuk. The Franklin FTSE Saudi Arabia ETF gives Saudi equity exposure. The SPUS (SP Funds S&P 500 Sharia Industry Exclusions ETF) covers US Shariah equity.

For Singapore-based investors using Tiger Brokers, the practical approach is: Indonesian government sukuk via government bond auctions (accessible through local Indonesian banks for Indonesian residents), or ETF exposure to high-grade MENA sovereign debt that includes sukuk allocations within broader EM bond fund structures. Direct sukuk access at retail scale remains the gap in the market — and it’s a gap that fintech companies in Malaysia and Indonesia are actively building products to close.

Not all sukuk are created equal. The Shariah compliance of a sukuk is certified by a Shariah advisory board — typically scholars in Islamic jurisprudence. But scholarly opinion on what constitutes true compliance varies across the AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions) standards and across different geographic schools of Islamic legal thought.

The most prominent controversy in recent memory: in 2007–2008, Sheikh Muhammad Taqi Usmani — one of the most respected Islamic finance scholars globally — declared that approximately 85% of outstanding sukuk structures were non-compliant with genuine Islamic principles because they essentially guaranteed return of principal in ways that resembled conventional bond guarantees. This sparked a structural reform debate across the industry that pushed issuers toward more asset-backed (as opposed to merely asset-based) structures.

The distinction is technical but commercially important. An asset-backed sukuk gives investors a genuine first claim on the underlying asset in a default scenario. An asset-based sukuk gives investors a claim on the originating entity, using the asset as a structural intermediary. The latter looks more like a conventional bond with Islamic labelling. Post-2008 reforms pushed the industry toward more genuinely asset-backed structures, but due diligence on any specific sukuk still requires understanding which structure applies.

The global Muslim population is 1.9 billion and growing. The wealth concentration within that population — particularly in the Gulf, in Malaysia, and in Indonesia’s emerging middle class — is increasing. PIF’s $1.15T AUM, Gulf sovereign wealth funds collectively managing over $3.2T, and Malaysia’s burgeoning Islamic asset management industry all represent capital pools with a preference for Shariah-compliant instruments. That preference creates sustained demand for sukuk issuance that is structurally growing faster than the conventional bond market.

Green sukuk — Shariah-compliant instruments that also meet ESG criteria for use-of-proceeds — are the fastest-growing segment. Saudi Arabia’s 2021 green sukuk, Indonesia’s sovereign green sukuk series, and Malaysia’s sustainability-linked sukuk programmes all tap the intersection of Islamic finance capital pools and ESG-mandated institutional capital. An institutional investor that is both Shariah-compliance-required and ESG-mandated — a large Gulf pension fund with environmental commitments — finds green sukuk the only instrument that satisfies both mandates simultaneously.

The $$900B sukuk market is growing. The structural drivers are demographic. The access gap for non-Muslim investors who want fixed income exposure to high-growth Islamic economies is narrowing as product infrastructure develops. And the yield premium over similarly-rated conventional bonds — a real phenomenon in thinner markets — represents genuine alpha for investors willing to do the structural diligence.

The asset class that nobody in mainstream financial media talks about properly is, by the measure of sustained growth and structural demand, exactly the kind of thing you want to understand before the coverage catches up with the market.
