Islamic Finance Structuring

A framework for structuring Sharia-compliant financings, grounded in the two governing prohibitions — riba (interest) and gharar (excessive uncertainty) — and the requirement that returns attach to real assets, real trade, or genuine risk-sharing.

Core Contract Library

Contract	Structure	Conventional analogue
Murabaha	Cost-plus sale with deferred payment; bank buys the asset, sells at disclosed markup	Term loan / trade finance
Tawarruq	Commodity Murabaha monetisation for liquidity	Cash facility
Ijara	Lease of an asset; bank owns, client pays rent; often with purchase undertaking (Ijara wa Iqtina)	Finance lease
Musharaka	Equity partnership; profit shared by agreed ratio, losses by capital contribution	Joint venture equity
Diminishing Musharaka	Partnership with progressive buyout of the bank's share	Amortising mortgage
Mudaraba	Investor (rab al-mal) funds, manager (mudarib) works; profit shared, losses to capital	Fund management
Istisna'a	Manufacture/construction contract with staged payments	Construction finance
Salam	Forward purchase with full prepayment (commodities)	Commodity forward
Wakala	Agency contract with agreed fee; agent invests on principal's behalf	Managed account
Takaful	Mutual protection pool with tabarru' (donation) mechanics	Insurance

Structuring Logic

The conversion discipline for any conventional structure: identify the economic function (funding, risk transfer, liquidity, security), then rebuild it from the contract library so that every return traces to an asset, a service, or shared risk. A conventional loan becomes Murabaha or Tawarruq; a lease facility becomes Ijara; project construction debt becomes Istisna'a flipping into Ijara at completion; a revolving facility becomes a Wakala pool. Purchase undertakings, service agency agreements, and rental benchmarking (to a market reference rate as an index, not as interest) supply bankability without breaching form.

Sukuk securitise these contracts: Ijara sukuk (asset-backed rental flows) dominate for ratability; Musharaka/Mudaraba sukuk carry genuine equity risk; Istisna'a and hybrid structures fund greenfield construction. The AAOIFI position requires true asset transfer for tradability — pure receivables (Murabaha paper) trade only at par.

AAOIFI Compliance Screens

Portfolio and counterparty screening ratios (applied in the RVS v4.0 credit model as an automatic verdict gate):

Debt / Total Assets < 33%
(Cash + Interest-Bearing Securities) / Total Assets < 33%
Non-compliant revenue / Total revenue < 5%

Failure of any screen triggers a one-tier verdict downgrade in credit decisions and requires purification (donation of tainted income) in portfolio management.

Governance

Every structure passes three gates: the Sharia board (fatwa on the structure), the regulator (banking-law perimeter), and external audit (AAOIFI accounting treatment, which differs materially from IFRS in profit recognition, asset ownership, and pool accounting). A structure that is compliant in form but replicates a prohibited economic outcome invites reputational and fatwa risk — substance review is part of the methodology, not an afterthought.

Output Protocol

Every structuring answer names the contract(s) used, traces the return to its permissible source, states the AAOIFI screen results, flags the governance path, and gives the conventional-equivalent economics for committee comparison.
