How to Compare Two Banks' Savings Products in Sudan (2026)

The information you need is not on the website

Start with an experiment. Open the savings pages of two Sudanese banks and try to answer a simple question: which one will pay me more?

You will not be able to. Not because you looked in the wrong place, but because the numbers are not published.

Bank of Khartoum's investment deposit account is a fair example, and it is more forthcoming than many. It tells you the product runs on the Mudarabah principle. It tells you the terms available — 3, 6, 9 or 12 months. It tells you profits can be paid out or reinvested with your original deposit at the end. It even tells you the product offers "higher profit rates than a normal Islamic savings account".

What it does not tell you is the minimum you need to open one. The page says a minimum is required, "which you can confirm when you apply". And nowhere does it promise a rate of return.

Neither of those is a flaw in that bank's website. Both are honest reflections of how these products actually work. But together they mean the comparison you want to do cannot be done from a screen. It has to be done by asking — and this guide is about asking the right things.

A ratio is not a rate

The first thing to get straight is what you are being quoted, because two different numbers get loosely called "the rate" and they are not the same thing.

A mudaraba deposit is an investment partnership. You supply capital; the bank invests it and manages the work. The profit that results is divided between you according to an agreed profit-sharing ratio — for instance, a split where the depositor takes one share and the bank takes another.

That ratio is fixed and agreed upfront. What it is a share of is not. The ratio tells you how the pie is divided, not how big the pie will be.

So if a bank tells you "the rate is X", establish immediately which number that is:

• A profit-sharing ratio — the agreed split. Fixed, knowable, comparable.
• An expected or indicative profit rate — the bank's projection of what that split will actually deliver. A forecast, not a promise.

Confusing the two is the single most common error, and it makes comparison meaningless. A generous-sounding ratio applied to weak returns can pay you less than a modest ratio applied to strong ones. If you take one thing from this article, make it this: get both numbers, from both banks. The mechanics behind them are covered in our guide to the basics of Sudanese banking.

One more point on where ratios come from. CBOS policy leaves the mudarib's profit share to be determined by each bank rather than fixing it centrally. That is precisely why comparing is worth your time — banks genuinely differ, and nobody is setting the split for them.

"Expected" is doing real work in "expected profit rate"

Under a genuine profit-sharing arrangement, your return depends on how the bank's investments actually perform. If they underperform, you receive less. The whole structure rests on the depositor sharing in the outcome — that is what makes the return permissible rather than a disguised interest payment, and the reasoning behind it is set out in our guide to how Sharia boards approve financial products.

This is why you should read the absence of a guarantee on a product page as information rather than an oversight. It is the structure being described accurately.

In practice, banks smooth returns and most depositors receive something close to what was indicated. But "close to, usually" is not "guaranteed", and you should size your expectations to the former. So ask directly:

• What did this product actually pay over the last several periods? Not the projection — the outcome. A bank that can answer readily is telling you something good about itself.
• How often is profit calculated and paid?
• Has the indicated rate and the paid rate ever diverged, and by how much?

The regulator treats these as investments, not safekeeping

There is a revealing detail in CBOS's own rules that most savers never see.

Islamic banks must hold a statutory reserve with the Central Bank, calculated on their deposits — but the rule computes it on "current deposits, savings deposits, other deposits" while expressly excluding "investment and similar deposits". CBOS policy has also allowed banks to direct a large share of investment deposits — 70% under the 2010 policy — into medium-term financing of more than a year.

Read those together and the regulator's view is clear. Your current account is money being held. Your investment deposit is money being put to work, at longer horizons, in a different category entirely.

That is not a warning against investment deposits. It is a reason to be clear about which product you are in, because the two behave differently when you need your money back — and because it bears directly on the protection question below.

The questions that make two products comparable

Take this list to both banks. The answers, side by side, are the comparison.

1. Which structure is this — mudaraba investment deposit, or a savings account?
2. What is the profit-sharing ratio? The split, in figures.
3. What is the expected profit rate, and what did it actually pay recently?
4. What is the minimum to open, and the minimum to maintain? Rarely published — always ask.
5. What terms are available? Three, six, nine and twelve months are common.
6. What happens if I withdraw early? Product pages routinely say "subject to terms and conditions" without stating them. Get the actual consequence.
7. How and when is profit paid — out, or reinvested? Reinvestment compounds your return, which over several terms is not a small difference.
8. What fees apply? Fees can quietly consume a modest profit share.
9. Is this deposit covered by the Deposit Guarantee Fund? See below — ask it explicitly.

Question 6 deserves emphasis. Locking money away for twelve months during a period of disruption is a real commitment. If your circumstances might change — and for many people in Sudan right now they might — a shorter term you can actually see through beats a longer one you have to break.

A worked comparison

Numbers here are unit-free ratios, deliberately. The Sudanese pound's volatility makes any fixed amount misleading within months.

You have 100 to place for twelve months.

Bank A offers a 12-month mudaraba deposit. Depositor share of profit: 60%. Expected profit rate: it indicates the deposit should return around 9 over the year. Profit paid at maturity.

Bank B offers a 6-month mudaraba deposit. Depositor share: 55%. It indicates around 4 per six-month term, with automatic reinvestment of profit.

Bank A looks better — 9 against roughly 8 over two terms. But work Bank B through properly. First term returns 4 on 100. Reinvested, the second term runs on 104, returning about 4.16. Total: 8.16.

So Bank A is ahead by roughly 0.84 on 100 — real, but much narrower than the headline ratio suggested. And Bank B leaves you a decision point at six months, which during a period of currency instability has genuine value that does not appear in either number.

Two lessons. Reinvestment matters — profit that compounds across terms closes gaps that look decisive on paper. And the shorter term carries optionality that the arithmetic alone will not show you. Run your own figures through the savings calculator, treating the rate input as the expected profit rate, and look at what accounts are available and how they compare on the banking side.

What about the Deposit Guarantee Fund?

Sudan has a deposit protection body — the Banks Deposit Security Fund, operating under a Deposit Guarantee Fund Act. It was reported in July 2026 to have resumed operations from its Khartoum headquarters after closing during the war, and to be shifting from compensating depositors after a bank fails toward helping prevent failures in the first place. The same account describes a sector carrying heavy wartime losses: destroyed branches, disrupted systems, falling deposits, and more money circulating as cash outside the formal system.

Now the honest part. We could not establish the Fund's coverage limit, or which categories of deposit it protects. Its website did not respond when we tried to check, and we are not prepared to repeat a figure we cannot source — on a question this consequential, a confidently wrong number is worse than none.

One gap matters more than the others, and it follows directly from the section above. Current and savings deposits are treated by the regulator as one kind of thing, and investment deposits as another. Whether mudaraba investment deposits enjoy the same protection as ordinary savings is not something you should assume in either direction. Ask your bank, in those words, and ask CBOS if the answer is vague. If a large share of your savings is going into an investment deposit, that answer is worth more than a fraction of a percentage point on the expected rate.

And before any of this: confirm the institution is licensed at all, using the method in our guide to checking a bank or lender is licensed. Protection schemes and profit shares are both meaningless outside the regulated system.

Where savings sit when prices are moving

A closing note that would be dishonest to omit. In a period of high inflation, a positive profit share does not guarantee that your savings hold their purchasing power. Money in a twelve-month deposit is money you cannot move if conditions change.

That is an argument for matching the term to the job — short, accessible savings for money you may need, longer terms only for money you genuinely will not — rather than an argument against saving. It is also worth thinking about alongside your other commitments: if you are carrying financing, the structures explained in our guide to murabaha home and vehicle finance behave differently on early settlement than a deposit does on early withdrawal, and the two decisions interact.

Frequently asked questions

Why won't the bank just tell me the rate? Because under a genuine profit-sharing arrangement there is no fixed rate to tell you. What the bank can give you is the profit-sharing ratio, which is agreed and firm, and an expected profit rate, which is a projection. Ask for both, and ask what the product actually paid recently.

Is a profit-sharing ratio the same as an interest rate? No. A ratio divides whatever profit is generated between you and the bank. An interest rate specifies a return regardless of performance. That difference is the substance of the arrangement, not a change of vocabulary — it is why your return can vary.

Can I lose money in a mudaraba deposit? Under the structure, the capital provider bears investment losses — that is what makes the return permissible. In practice Sudanese banks manage and smooth returns, and this is not the usual experience. But it is why a bank does not guarantee a return, and why the deposit-protection question above is worth asking directly.

Is my investment deposit covered by the Deposit Guarantee Fund? Ask your bank explicitly, and ask CBOS if the answer is unclear. We were unable to establish which deposit categories the Fund covers from a source we trust, and we are not going to guess. Given that the regulator treats investment deposits differently from savings deposits in other respects, do not assume they are treated identically here.

Is a longer term always better? No. A longer term may indicate a higher return, but it removes your ability to react — and during a period of instability that flexibility has real value. A shorter term with automatic reinvestment can produce a similar result while leaving you a decision point along the way.

How do I compare products if neither bank publishes minimums? You ask, and you ask both on the same day. Minimums, early-withdrawal terms and fees are frequently absent from published pages. Write the nine questions above on a piece of paper and get answers to all of them from each bank before deciding.
