Contested question 6 of 10
Why do halal providers benchmark to SOFR, Treasury yields, or conventional mortgage rates?
Because there is no deep halal money market to price against, providers use conventional benchmarks to set the rent, markup, or profit rate. The dominant scholarly view is that using a benchmark to price a permissible contract does not make the contract interest-based, in the same way that a halal butcher may price lamb by reference to the supermarket's price. The dissent is that benchmarking reveals that the economics are the same.

- Benchmarking is a pricing convention, not a contract term (Mufti Taqi Usmani)
- Benchmarking is evidence of substance (El-Gamal and other critics)
- Permissible now, with an obligation to move away (Several contemporary boards and the Islamic Financial Services Board (IFSB) in guidance)
- The facts of the specific contract decide which position applies; verify before you sign

The criticism, at full strength
If the 'profit rate' moves in lockstep with the Fed, the product is a loan priced like a loan.
What is true in it
- Most U.S. halal home-financing and auto products are priced with reference to conventional rates, and many disclose this.
- Adjustable 'rent' in diminishing Musharakah often resets to a conventional index.
The documented positions
1Benchmarking is a pricing convention, not a contract term
Held by
Mufti Taqi Usmani; AAOIFI; most industry scholars
Reasoning
The ruling attaches to the contract (sale, lease, partnership), not to how the price was arrived at. Using an interest benchmark is undesirable and the industry should develop Islamic benchmarks, but it does not invalidate the contract.
2Benchmarking is evidence of substance
Held by
El-Gamal and other critics
Reasoning
When the financier's return is contractually tied to an interest rate, the 'rent' or 'profit' is interest in economic fact. The industry's failure to develop its own benchmarks after decades suggests the products are designed to replicate loans.
3Permissible now, with an obligation to move away
Held by
Several contemporary boards and the Islamic Financial Services Board (IFSB) in guidance
Reasoning
Benchmarking is tolerated as a necessity of a young market, but the obligation to develop and adopt Shariah-compliant benchmarks is real, and continued reliance without effort is criticized.
Where the difference shows up: the Fed raises rates 1% in year 2
A diminishing Musharakah with an adjustable rent that resets annually to a conventional index plus a margin, on a home where the provider still owns 70%. When the index rises 1%, your rent rises. Critics say: that is an adjustable-rate mortgage. Defenders say: rent on a house the provider co-owns can be set any way the parties agree, including by reference to an external number, as long as the thing being paid for is the use of a real asset. The test that separates the two is what you are paying for and who owns what, not what number was used to set the price. A landlord may set rent by reference to the local mortgage rate without the lease becoming a loan. What would make the critics right about a specific product is if the provider did not actually bear ownership risk, so the 'rent' was a return on money rather than on an asset. Scholars on both sides agree the industry should develop Islamic benchmarks; several attempts (including Islamic interbank rates in Malaysia and the Gulf) exist but have not displaced conventional indices in U.S. pricing.
| Point of difference | Conventional | Compliant structure |
|---|---|---|
| What the payment is for | Use of money | Use of a co-owned asset |
| How the price is set | Index + margin | Index + margin (same method) |
| Who bears asset risk | Borrower | Shared in proportion to ownership |
What to verify before you decide
- Ask what index, if any, the rate or rent resets against and how often.
- Ask whether the provider's Shariah board has addressed benchmarking in its fatwa.
- Compare the fixed-rate option, which avoids resets to an interest index.
Bring the answers, and the contract, to your scholar. If a provider will not answer these in writing, that is itself an answer.

How to use this comparison: Scholars rule; we organize the evidence. HalalWallet is an independent educational comparison platform - by design, we do not issue fatwas or provide financial, legal, or tax advice. We do the research homework so your final checks are quick and personal. Where our role ends and who takes over.
Product structures and Shariah oversight vary by provider, so finish with three built-in steps:
- Confirm current terms and halal compliance directly with the provider - their quote is final.
- Review the contract structure (Murabaha, Ijara, Musharakah, etc.) and any disclosed Shariah board opinions.
- Bring your shortlist to a qualified Islamic finance advisor or scholar, so the conversation is about your situation, not the basics.
