Njangi and Tontines in Cameroon: How to Run One Safely (2026)

What a njangi actually is

A njangi — tontine in French, and the two words are used interchangeably across Cameroon — is a group of people who agree to put money in on a fixed schedule and take it out under a fixed rule. That is the whole idea, and it is why it has outlasted every financial product marketed against it. In the Northwest and Southwest it is often a workplace, church or hometown group meeting monthly; in Douala and Yaoundé it may be a WhatsApp group with an MTN MoMo or Orange Money collection number. The mechanism is the same.

Njangi money does real work that a bank account does not. It forces saving, because letting the group down carries a social cost that skipping a savings transfer never will. It gives you a lump sum earlier than you could have saved one alone, with no account fee, no minimum balance and no paperwork.

It also carries a risk that no bank account carries, and this guide is mostly about that: no regulator stands behind a njangi, and nobody is going to compensate you if it fails.

The three shapes a njangi takes

Most circles are one of these, or a blend. Knowing which one you are in tells you what can go wrong.

The rotating pot. Everyone contributes the same amount each meeting and one member takes the whole pot, in rotation, until everyone has had a turn. Nobody earns anything; the benefit is timing. The risk sits at the end — a member who has already collected has much less reason to keep paying, so the last people in the rotation carry the default risk for everyone.

The savings-and-loan circle. Contributions build a common fund that members borrow from at an agreed rate, and the fund plus interest is shared out at a set date, often before Christmas or the school year. This one grows money rather than just moving it, and it is also the one that most often collapses — because it holds a large balance between meetings, and it lends.

The mutual-aid fund — the "trouble bank" in Anglophone usage. A separate, smaller contribution that pays out on a defined event: a funeral, a hospital admission, a birth. Insurance in structure, though not in law, so what it pays and when must be written down or it becomes an argument at the worst possible moment.

What no njangi gives you

Cameroon does have a deposit guarantee, and it is worth knowing precisely what it protects — because the answer is not "your savings" in general.

FOGADAC — the Fonds de Garantie des Dépôts en Afrique Centrale, created by CEMAC regulation n° 01/09/CEMAC/UMAC/COBAC of 20 April 2009 and operating since February 2011 — pays out when a credit institution fails. Its published ceiling is 5,000,000 FCFA per client, per institution, and the fund is financed principally by contributions from the credit institutions themselves. A njangi contributes nothing to it and is not one of those institutions, so nothing in that scheme reaches a njangi's pot. Our FOGADAC deposit protection explainer covers how the guarantee works where it does apply.

Nor is there a supervisor to complain to. COBAC — the regional banking commission — supervises banks and licensed microfinance establishments. A group of colleagues collecting between themselves is not on that list, which is exactly why it can operate freely, and exactly why your only protection is the group's own rules and the people in it.

Whether money held at a licensed microfinance establishment falls inside that guarantee is a separate question, and one worth settling before you choose where a group's savings sit. FOGADAC's own published presentation speaks of protecting depositors on the failure of a credit institution, and does not set out the position for EMFs. Secondary commentary suggests microfinance depositors are treated differently from bank depositors, at a materially lower effective ceiling — but we could not confirm that against FOGADAC or COBAC directly, so we are not going to state a figure for it here.

What to do about it: if your njangi's money is going into an EMF rather than a bank, ask that institution in writing whether its deposits are covered by FOGADAC and up to what amount, and confirm the answer with FOGADAC (contactable through BEAC) or COBAC rather than taking the institution's word for it. The gap between a guaranteed 5,000,000 FCFA and no guarantee at all is precisely the kind of thing a group should know before it commits several years of contributions.

Rules that keep a circle from collapsing

Circles rarely fail because someone plans to steal. They fail because nothing was written down, so when a member's situation changes there is no agreed answer. Before your group's next cycle, settle these — in writing, signed, one copy each:

The amount, the date and the grace period. Not "month end" — a date, and how many days late is still acceptable.
The penalty for late or missed payment, agreed in advance by everyone, and applied to the first person who is late. A penalty nobody enforces is not a rule.
How the collection order is decided. Draw, seniority, or need — any of them works, provided it was decided before anyone knew who would be first, and written down.
Two signatories, always. Any movement of money needs two named people. This one rule prevents most of what goes wrong.
Where the money sits between meetings. Not in a treasurer's house and not in a treasurer's personal wallet. A dedicated account at a licensed institution, in the group's name where possible — see how to open a bank account in Cameroon for what the KYC process asks for.
A written register. Date, member, amount in, amount out, running balance, read aloud at every meeting. Anyone can dispute it that day; nobody can dispute it a year later.
What happens when a member leaves, defaults or dies. Especially in the rotating pot: does someone who has already collected still owe the rest? Write the answer down while everybody is friendly.

If your group collects by mobile money, use one collection number — never a personal number that also does personal business — and keep the confirmation messages. How to cut your mobile-money charges in Cameroon explains where MoMo and Orange Money fees leak, which matters more than most groups realise when the same pot is moved twelve times a year.

The line a growing circle should not cross by accident

There is a point where a njangi stops being a private arrangement between people who know each other and starts doing something that Cameroonian and CEMAC law reserves for licensed institutions. Taking savings from the public, and lending, is microfinance activity — and under the framework COBAC supervises, an establishment doing it must be approved and must fit one of three categories:

First category — savings and credit for members only, in cooperative or mutual form, formed by solidarity groups. This is the category the credit-union tradition of the Anglophone regions sits in.
Second category — collects savings from the public and grants credit, as a commercial company, and is held to noticeably stricter regulatory requirements precisely because it solicits public money.
Third category — grants credit only, and may not collect savings.

The warning signs that your circle is drifting across that line: it admits people no member actually knows; it advertises; it promises a return rather than sharing what was actually earned; or it takes money from non-members "to invest". Any of those and the group is no longer a njangi in substance, whatever it still calls itself.

The framework here is CEMAC-wide and administered by COBAC, whose published regulations govern the conditions for exercising and controlling microfinance activity across the community. We are deliberately not describing the specific penalties for unauthorised deposit-taking, because the current consolidated text is published as scanned images we could not read reliably, and a wrong statement about a sanction is worse than none. What is not in doubt is the direction of the risk: taking public savings without approval is a problem for the organisers of a group, not only for its savers. If your circle is anywhere near that line, put the question to COBAC or a Cameroonian lawyer before it grows further, not after.

When to formalise, and how

Formalising is what you do when the amounts get large enough that trust alone is carrying too much weight. Two routes exist:

Register the group as a cooperative. For a new registration, the governing text is the OHADA Uniform Act on cooperative societies, adopted at Lomé on 15 December 2010, published in the OHADA official journal on 15 February 2011 and in force since 15 May 2011 across the member states, Cameroon included. It superseded the national regime that Cameroonian cooperatives had operated under — Law No. 92/006 of 14 August 1992 on cooperative societies and common initiative groups — to the point that cooperatives formed under the older law were required to bring their statutes into line with the Uniform Act, under its articles 390 to 394, either by amending the old bylaws or redrafting them entirely.

The practical implication for a njangi considering this route: you are registering under OHADA rules, not the 1992 law, and if your group is an older one already carrying pre-2011 statutes, those may need harmonising rather than simply being carried forward. Registering gives the group a legal identity separate from its members, so the money and any assets belong to the cooperative rather than to whoever's name they happen to be in. Confirm the current procedure, the minimum membership and where you file with a notary or the competent ministry before starting — the registration formalities sit in national implementation rather than in the Uniform Act itself.

Move the savings function to a licensed institution and keep the circle social. Often the better answer: the discipline, the meetings and the mutual aid stay exactly as they are, while the balance sits in an account at a licensed bank or a first-category credit union. You keep what a njangi is good at and stop asking one member's cupboard to be a vault.

Before choosing where, check the institution actually appears on the Ministry of Finance's published list of licensed microfinance establishments, which MINFI issues annually and publishes on minfi.gov.cm. The list is dated to the preceding 31 December and authorises those establishments for the following year — the edition drawn up as at 31 December 2025 covers 385 licensed EMFs operating through 2026, slightly down from 390 the year before. MINFI's stated reason for publishing it is precisely to steer people away from clandestine operators, which is exactly the check worth running before a group hands over years of contributions.

If the institution your group is considering is not on that list, that is the end of the conversation, not a detail to follow up later.

Frequently asked questions

Is a njangi legal in Cameroon? A private savings circle among people who know each other is a normal part of Cameroonian financial life, and not what the microfinance licensing regime is aimed at. What requires approval is collecting savings from the public and lending as a business.

Is my njangi money protected if the circle collapses? No. The FOGADAC deposit guarantee pays depositors when a credit institution fails, at a published ceiling of 5,000,000 FCFA per client per institution. A njangi is not a credit institution and contributes nothing to that fund, so it sits outside the scheme entirely.

Someone collected their turn and stopped paying. What now? This is the most common njangi failure, and the only real defences are the ones set before it happened: a signed written agreement, an enforced late penalty, and a rule stating whether a member who has already collected still owes the remaining cycle. Without those, recovery is difficult — and what a court would do is not something to assume, so take specific legal advice.

Should the treasurer keep the money at home? No. Between meetings the balance should sit in an account at a licensed institution, with two signatories required to move it. Cash held personally is the single largest source of njangi loss — through theft, a household emergency, or an honest mistake nobody can reconstruct later.

Can a njangi charge interest on loans to its members? Circles commonly do, and share the proceeds at the end of the cycle. If your group lends, the rate, term and borrower should be decided by the group and written into the register, never left to a treasurer's discretion.

When should we register as a cooperative? When losing the balance would hurt badly, when membership has grown past the people who genuinely know each other, or when the group wants to own something — a building, a vehicle, a business stake.
