Ask a simple question of Nigerian non-interest banking: what did savers earn last month? As of our provider crawls dated 4 August 2026, no Nigerian non-interest bank will tell you. Not in a rate sheet, not in a monthly declaration, not in a footnote. This article maps the disclosure landscape precisely, bank by bank, because the gap between what these institutions publish about structure (a lot) and what they publish about outcomes (nothing) is the single most consumer-hostile feature of an otherwise improving market.

The disclosure scorecard
| Bank | Contract types published | Deposit profit rates | Sharing ratio | Financing prices |
|---|---|---|---|---|
| Jaiz Bank | Yes, across the shelf | No | No ('pre-agreed', unprinted) | Only EnerJaiz solar (28-30% p.a.) |
| TAJBank | Yes, across the shelf | No | No; weightage method unpublished | No |
| Lotus Bank | Yes, across the shelf | No | No; Savers page self-contradicts | No; all 'competitive' |
| The Alternative Bank | Partially (some retail pages name none) | No | No | Yes: SME lines at 9% to 30% p.a. |
| Summit Bank | Yes (Qard Hasan, Mudarabah) | No (no history exists yet) | Disclosed at application only | No |
Read the pattern: every bank is comfortable telling you the fiqh and uncomfortable telling you the figures. The Alternative Bank proves the constraint is not legal or religious: it publishes SME financing markups down to the percentage point (AltBiz 15.5% flat, AltLease 30%, SWAY AG 9%, Social Mobilization 9.5%). Jaiz publishes complete pricing for one product, EnerJaiz solar finance. If financing prices can be published, deposit distributions can be too.
Why this matters more in Nigeria than elsewhere
Nigeria's macro environment makes yield opacity expensive. Inflation ran from 22% to 34% during 2024 and the monetary policy rate reached 27.5%, meaning cash that earns nothing, or earns an unverifiable something, loses purchasing power fast. The comparison products are brutal about this: the May 2025 FGN sukuk paid a published 19.75% annual rental, and Nigeria's SEC-registered Shariah funds reported an average year-to-date yield of 16.66% in March 2026 per SEC data. A saver choosing between a bank Mudarabah account with no published history and a sukuk with seven years of on-schedule payments at printed rates is not really facing a choice. The banks are losing their most rate-aware customers to the capital market, and publishing their distributions is the obvious fix.
What other markets prove is possible
None of this is inherent to Islamic banking. In mature markets, Islamic banks publish monthly declared profit rates, the depositor-bank sharing ratio for each pool, and the weightages assigned to each product tier, before the month begins, with the declaration signed off under a Shariah governance framework. Pakistani Islamic banks, which we cover on our sister site, archive years of monthly rate PDFs. The mechanics Nigerian banks already run internally (pools, ratios, weightages) are the same; the only missing step is publication. The CBN's framework mandates Advisory Committees of Experts and FRACE oversight but does not currently force distribution disclosure, so market pressure is the realistic driver.
How to protect yourself today
- Before opening any Mudarabah or Musharakah account, ask the branch in writing for the current profit-sharing ratio and the last six months of distributions to your product's tier.
- If the bank will not put the ratio in writing, treat the account as zero-yield custody and size your balance accordingly.
- Split roles: Qard current account for transactions, and put documented-return instruments (FGN sukuk from N10,000, Shariah funds from N5,000) alongside bank savings rather than inside them.
- Re-ask quarterly. Ratios and pool performance change, and a bank that knows customers check is a bank with an incentive to publish.
- Compare structures, fees and features, which are published, on our bank accounts page, and yields where they exist on our investing pages.
The honest counterpoint
Two fairness notes. First, non-guaranteed returns are the point of Mudarabah, and a bank that refuses to promise a rate is being more honest than one that quietly guarantees returns while calling them profit share. The critique here is about publishing outcomes, not promising them. Second, the sector is young and capital-constrained: the CBN's 2024 recapitalisation (N20 billion for national non-interest banks) and the May 2025 launch of non-interest liquidity instruments consumed management attention that might otherwise have gone to disclosure infrastructure. Neither point excuses the gap; both explain it. The first Nigerian bank to publish monthly declared distributions will win a disproportionate share of the market's most serious savers, and deserve to.
Frequently asked questions
Is a bank allowed to tell me the ratio at the branch?
Yes, and it must: the profit-sharing ratio is a contract term you agree before investing. The failure is publication, not existence. Any branch can print your product's current ratio; make them.
Are the banks hiding poor returns?
Unknown, and that is precisely the problem. In a high-rate environment the underlying halal assets (Murabaha markups, Ijarah rentals, sukuk) earn well, so distributions may be perfectly respectable. Without publication, savers cannot distinguish a good pool from a stingy split.
Do any halal products in Nigeria publish real yields?
Yes. FGN sukuk rentals are printed in offer documents (11.20% to 19.75% across the 2017-2025 series). SEC-registered Shariah funds publish NAVs and returns weekly. The Alternative Bank publishes SME financing prices. The disclosure desert is specifically bank deposit distributions.
Could the CBN force disclosure?
It could, and precedents exist in other jurisdictions where regulators require pre-announced weightages and prompt post-month declarations. Nothing in the current Nigerian framework compels it, so for now the pressure has to come from customers who ask, in writing, every time.
Does opacity make these accounts haram?
No. The contracts are valid: ratios are agreed at account opening even if unpublished, and the underlying assets are screened. Opacity is a consumer protection failure, not a Shariah one. It affects whether you can compare banks, not whether your profit is halal.
What exactly should I ask my branch for?
Three documents, in writing: the current profit-sharing ratio for your specific product and tier; the actual profit distributed to that product over the last six months, month by month; and the calculation basis (average balance, minimum balance or daily accrual). Every bank has these numbers internally. A branch that cannot or will not produce them is telling you something useful, and five licensed institutions compete for your deposit.
Do Nigerian banks smooth depositor returns?
Nobody says. In mature Islamic banking markets, banks openly operate profit equalisation reserves that steady depositor payouts across good and bad quarters, disclosed in their accounts. Nigerian non-interest banks disclose neither smoothing mechanisms nor raw pool performance, so depositors cannot tell whether their monthly credit reflects actual period results or managed distribution. Disclosed smoothing is accepted practice; undisclosed anything is the sector's recurring weakness.
How do funds and sukuk publish yields when banks do not?
Different regulators and different instruments. SEC-registered Shariah funds must publish net asset values, which is why their yields are public (an average of 16.66% year-to-date was published across the segment in March 2026), and the DMO prints every FGN sukuk rental rate in the offer documents. Bank deposit disclosure sits with the CBN, which currently mandates none. The comparison is uncomfortable for the banks, which is precisely why savers should keep making it.

Is this opacity unique to Nigeria?
No, but Nigeria sits at the opaque end of the spectrum. Mature Islamic banking markets routinely publish monthly declared profit rates for deposit products, proving that disclosure and Shariah compliance coexist comfortably. Nigeria's sector is younger and its banks have not yet faced the competitive pressure that forces publication; the first one to publish will make the others explain why they do not.
