Islamic banking

Islamic banks operate under contracts and governance structures designed to comply with Islamic commercial law, using sale, lease and partnership-based instruments in place of interest-bearing loans. This page describes the structure of Islamic banking and its distinctive prudential risks, including rate-of-return risk, displaced commercial risk and liquidity management constraints, as studied by supervisors and standard setters. It is professional risk research only: it gives no religious rulings and takes no position on the permissibility of any product.

01In brief

The short answer.

Islamic banking is banking under contracts and governance designed to comply with Islamic commercial law, using sale, lease and partnership instruments in place of interest-bearing loans. Its risks follow its contracts: returns shared with investment account holders, narrower liquidity tools and an added Shariah governance layer, with prudential standards set by the IFSB.

03The question

Islamic banking: how the risk develops.

Islamic banking structure and professional risk research without religious rulings. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Contract structure shapes risk

Murabaha sale, ijarah lease, musharakah and mudarabah partnerships and sukuk carry different mixes of credit, market, equity and operational risk. The risk profile depends on the contract's actual terms, not on its label.

Mechanism

Investment accounts share returns

Profit-sharing investment account holders bear losses in principle. Competitive pressure can lead banks to smooth returns and absorb losses themselves, a transfer known as displaced commercial risk.

Mechanism

Liquidity tools are narrower

A limited stock of eligible high-quality liquid assets and fewer compatible interbank and central bank facilities can make liquidity management harder in stress, particularly in shallow sukuk markets.

Mechanism

Governance adds a layer

Shariah governance boards and compliance review sit alongside the usual board and control functions. Failure to comply with adopted standards can lead to forgone income and legal and reputational risk, treated as operational risk.

09Core questions

Shared questions the industry asks.

  1. 01

    How do contract structures change risk?

    How sale-based, lease-based and partnership contracts distribute credit, market and operational risk.

  2. 02

    How is liquidity managed?

    How banks manage liquidity with limited compliant instruments and markets.

  3. 03

    What is displaced commercial risk?

    How banks manage pressure to pay competitive returns to investment account holders.

  4. 04

    How do shocks reach Islamic banks?

    How real-economy and hazard exposures pass through asset-backed financing.

10Mechanisms

How the risk arises and transmits.

Islamic banks finance through contracts such as cost-plus sale, leasing and partnership. Because financing is tied to real assets, banks may bear asset and market risks that conventional lenders do not, such as ownership risk in leasing.

Liquidity management can be harder. Compliant short-term instruments and interbank markets are less developed in some jurisdictions, which can lead banks to hold more cash or face constraints in stress.

Profit-sharing investment accounts introduce displaced commercial risk: banks may forgo income to pay returns comparable to competitors, so depositors' expected risk-sharing may in practice fall on shareholders.

Governance includes Shariah supervisory boards that rule on compliance. These rulings are matters for each institution's own scholars; GRA research takes no position on them.

Prudential standards for Islamic banks have been developed by specialized standard-setting bodies alongside general banking frameworks, and their application varies by jurisdiction.

13Questions

Questions and answers.

Does Banking Nexus give Shariah rulings?
No. Rulings are made by qualified scholars and Shariah governance bodies under their own mandates. This page covers prudential structure and risk as studied by supervisors and standard setters.
What is displaced commercial risk?
The risk that a bank pays investment account holders more than the underlying assets earned, to stay competitive, and so absorbs losses that in principle fall on the account holders.
Which standards apply to Islamic banks?
National law and supervisory rules, often drawing on the prudential standards of the Islamic Financial Services Board alongside Basel standards, and in some jurisdictions on AAOIFI standards for accounting and governance.
Why can liquidity management be harder?
Instruments compatible with Islamic finance principles, such as short-term sukuk and dedicated central bank facilities, are less abundant in many markets, which limits the tools available in stress.
Does GRA say whether a product is Shariah-compliant?
No. GRA issues no religious rulings. Compliance is decided by each institution and its own Shariah scholars.
Is Islamic banking riskier than conventional banking?
Its risks differ in kind, for example asset ownership and liquidity management. Research compares them without ranking institutions.
Who takes part in this research?
Banking risk professionals and researchers, under the same competition safeguards as all GRA work.
