Sukuk for Non-Muslim Investors: Structure, Risk, and Portfolio Role

Sukuk have grown from a niche Islamic finance instrument into a global fixed-income asset class, with total outstanding sukuk surpassing $1 trillion at the end of 2025. Sovereign issuers from the UAE, Saudi Arabia, Malaysia, and Indonesia — and, notably, the UK government — have issued Sukuk alongside conventional bonds. Major investment banks from Goldman Sachs to HSBC structure and distribute them. For sophisticated investors, the question is not whether Sukuk are "Islamic" in a cultural sense but whether they offer diversification, yield, and credit quality characteristics worth incorporating into a fixed-income portfolio.

Why Sukuk Is Technically Not Debt

Islamic law (Sharia) prohibits riba — conventionally translated as usury or interest — as well as excessive uncertainty (gharar) and investment in prohibited activities. A conventional bond, which involves lending money at a fixed interest rate, is incompatible with these principles.

Sukuk circumvents this by restructuring the economic relationship. Instead of lending money and receiving interest, Sukuk investors typically hold certificates representing ownership of — or beneficial interest in — an asset, business activity, or project. The "return" they receive is structured as rental income, profit share, or a portion of trade profits rather than interest.

Economically, Sukuk and conventional bonds can be almost indistinguishable in terms of cash flow profile, maturity, and credit exposure. A sovereign Sukuk may pay a "profit rate" of 4.5% per annum on a 5-year tenor in a structure that delivers near-identical cash flows to a 4.5% conventional bond. The difference lies in the legal architecture and the assets underpinning the obligation, not necessarily in the investment outcome.

This matters for non-Muslim investors because it means Sukuk are not exotic instruments with unfamiliar risk profiles. They are fixed-income instruments with a structured asset backing, issued by creditworthy sovereigns and corporates, rated by Moody's, S&P, and Fitch, and tradeable in secondary markets.

Main Sukuk Structures

Ijara (lease-based Sukuk) is the most common sovereign structure. The issuer identifies an asset — government buildings, infrastructure, aircraft — sells them to an SPV (the Sukuk trustee), which then leases the assets back to the issuer. Sukuk investors hold certificates representing co-ownership of the SPV's assets. The lease payments constitute the periodic "coupon" payments, and the principal is returned at maturity through the issuer repurchasing the assets. Sovereigns favour this structure because it provides a clean legal framework with tangible underlying assets.

Murabaha (cost-plus-profit Sukuk) involves the SPV purchasing commodities or other goods on behalf of the end-user, then selling them at a mark-up on a deferred payment basis. The mark-up constitutes the profit payment to investors. Murabaha is commonly used in shorter-tenor and corporate transactions.

Musharaka (partnership Sukuk) creates a joint venture between the Sukuk issuer and investors. Profit is shared according to a pre-agreed ratio; losses are borne in proportion to capital contribution. This structure aligns more closely with equity economics and is less common for investment-grade fixed-income purposes.

Wakala (agency Sukuk) and Mudaraba (profit-sharing Sukuk) are used in specific contexts, often for financial institution issuers. Wakala involves an agent managing a portfolio of assets on behalf of Sukuk holders; the portfolio generates returns that pass through to investors.

For practical purposes, most liquid investment-grade Sukuk accessible to UK investors are Ijara or Murabaha structures from sovereigns or quasi-sovereigns rated BBB or above.

UK Government Sukuk Issuance

The United Kingdom first issued sovereign Sukuk in 2014, making it the first non-Muslim-majority country to issue a sovereign Sukuk. A £200 million, 5-year Ijara Sukuk was issued at par with a 2.036% profit rate. It was significantly oversubscribed, with demand from both Islamic and conventional investors across the Middle East, Asia, and Europe.

The UK government issued its second sovereign Sukuk in 2021 — a £500 million, 5-year instrument maturing in 2026 — again Ijara-structured, backed on UK government-owned properties. The transaction demonstrated broad appetite beyond the Islamic investor base, with conventional fund managers and central banks participating alongside Islamic finance institutions.

The Debt Management Office's motivation was explicit: access a diversified investor base and demonstrate London's credentials as a global Islamic finance centre, which it remains — the UK has the largest Islamic finance sector of any non-Muslim-majority country. For investors, UK sovereign Sukuk function as close equivalents to gilts, with sovereign credit quality, sterling denomination, and comparable yields.

Major GCC and Asian Issuers

The Gulf Cooperation Council (GCC) countries — Saudi Arabia, UAE, Qatar, Kuwait, Bahrain, and Oman — are the largest Sukuk issuers globally. Saudi Arabia's Public Investment Fund (PIF), the Abu Dhabi Investment Authority (ADIA), and a range of GCC development agencies regularly issue benchmark-sized Sukuk alongside conventional bonds.

Saudi Aramco, the Abu Dhabi National Energy Company (TAQA), Emirates airline, and Dubai Ports World (DP World) are among the prominent corporate issuers. These companies maintain investment-grade ratings and issue Sukuk that trade at yields closely comparable to their conventional bonds — the spread differential between a corporate's Sukuk and its conventional bond is typically narrow (5–15 basis points).

Malaysia is the largest market by number of issuances, with a deep domestic Sukuk market dominated by the Malaysian ringgit. Indonesia has become a significant dollar-denominated sovereign Sukuk issuer, with 10-year sovereign Sukuk trading at spreads reflecting its BBB rating. Both markets are accessible via diversified EM Sukuk funds.

Risk Profile Compared with Conventional Bonds

Credit risk is comparable. The creditworthiness of a Sukuk issuer is assessed using the same analytical framework as conventional bonds: sovereign ratings, corporate balance sheets, cash flow coverage, and peer comparisons. A UAE sovereign Sukuk rated AA carries similar default probability to a UAE sovereign conventional bond with the same rating.

Structure risk is incremental. The additional legal complexity of Sukuk structures — particularly around asset transfer, beneficial ownership, and Sharia board compliance — creates risks not present in conventional bonds. In a default scenario, the enforceability of asset-backed claims has been tested in only a limited number of cases; investors should not assume recovery rates will be identical to equivalent conventional bonds. The Nakheel Sukuk restructuring in 2009 illustrated that in practice Sukuk defaults are resolved through negotiation similar to conventional defaults, but the legal process can be more complex.

Sharia compliance risk arises if a Sukuk is subsequently determined not to comply with Sharia requirements. While this does not create a legal default, it could affect pricing if Islamic investors are required to exit — an unusual but not impossible scenario.

Liquidity risk for Sukuk is generally higher than for comparable-rated conventional bonds. Secondary market trading is thinner, bid-offer spreads are wider, and the investor base is more concentrated. In stressed conditions, Sukuk can be harder to sell at mid-market prices.

Currency risk applies to non-sterling or non-dollar denominated Sukuk. Most GCC sovereign Sukuk are US dollar denominated (benefiting from dollar pegs), which provides a natural hedge for dollar-based investors but creates FX exposure for sterling-based investors.

Access via ETFs and Funds

For most HNW investors, direct access to individual Sukuk requires minimum denominations (typically $200,000 or equivalent) and a relationship with a bank or broker active in Islamic capital markets. Practical access routes include:

UCITS ETFs: The iShares J.P. Morgan $ EM IG ESG Sukuk UCITS ETF and the Franklin Sukuk UCITS ETF provide broad exposure to investment-grade dollar-denominated Sukuk from GCC and Asian issuers. Liquidity is reasonable, TERs are broadly comparable with active Sukuk funds.

UCITS Sukuk funds: Managers including Amundi, Franklin Templeton, and several specialist Islamic asset managers run actively managed UCITS Sukuk funds investing across the sovereign and corporate Sukuk universe. Active management in Sukuk markets has historically added value given the less efficient price discovery and greater dispersion of credit quality versus the IG corporate bond market.

Discretionary mandates: For larger allocations (typically above £250,000), a discretionary manager can build a diversified Sukuk portfolio alongside conventional fixed income, managing duration, currency, and credit quality at the portfolio level.

Portfolio Role for Non-Muslim Investors

Sukuk deserve consideration on purely financial grounds: they offer diversification into GCC and Asian sovereign and corporate credit, are denominated primarily in US dollars (reducing currency complexity), carry investment-grade ratings on the largest benchmark instruments, and provide access to creditworthy issuers that do not typically issue in sterling bond markets.

The GCC Sukuk universe has historically shown low correlation with European corporate bonds, partly reflecting the different economic drivers of Gulf economies (hydrocarbons, infrastructure spending, fiscal surpluses) and partly the concentrated, sticky Islamic investor base that limits forced selling in risk-off environments.

A modest allocation (5–10% of fixed-income exposure) to investment-grade Sukuk can broaden diversification without materially increasing credit risk, provided currency exposure is managed appropriately.

Investments can fall as well as rise in value. Fixed-income instruments carry interest rate, credit, liquidity, and currency risk. Sukuk carry additional structural and Sharia compliance risks.
