Sou-sou: how it works and how to stay safe

6 min read · Before you start: Saving and where to keep it · Updated 2 November 2026

Key terms in this lesson: sou-sou · emergency fund (all defined in the glossary)

A sou-sou is one of the oldest ways Caribbean households save. There is no bank, no form and no interest: a group agrees to put in the same amount on a regular date, and each member takes the whole pot in turn. It works because people keep promises to people they know. It can also go wrong for exactly the same reason, so this lesson covers how it works, what it can cost you, and how to tell a real sou-sou from something that only borrows the name.

What a sou-sou is

A sou-sou (also written susu) is a rotating savings group. Around the Caribbean the same idea goes by other names, including partner and box. The parts are the same everywhere:

• Members who each pay a fixed amount every week, fortnight or month.
• A hand: one share in the pot. Some members take more than one hand, paying more and receiving more than once.
• The pot: the total collected in one round, paid to one member.
• The banker: the person who organises the group, collects the money, pays out and keeps the list.
• The order: who receives the pot in which round, agreed in advance or settled by drawing numbers.

The group finishes when every hand has received its pot once. By then each member has paid in exactly what they received.

A worked example

Ten people each put in TT$500 a week, one hand each. The pot is 10 × TT$500 = TT$5,000, and the group runs for ten weeks.

• First hand: receives TT$5,000 in week 1, after paying TT$500. They still owe TT$500 a week for the remaining nine weeks, TT$4,500 in all.
• Last hand: pays in every week and receives TT$5,000 only in week 10.
• Everyone pays TT$5,000 in total and receives TT$5,000. Nobody earns anything.

The order is the whole game. An early hand is an interest-free loan from the rest of the group, and the borrower must keep paying until the end. A late hand is an interest-free loan to the group, with a long wait before it comes back.

Why people use them

• It enforces the habit. A promise to the group is harder to break than a promise to yourself.
• It builds a lump sum for school books, Christmas, a deposit or a repair, without a loan.
• There are no fees and no interest to pay. No credit check is needed either, only trust.

The risks

• No legal protection. There is no regulator and no deposit insurance, and recourse if someone stops paying is limited. Lesson 18 explains what formal protection does cover.
• Default. If a member who has already received the pot stops paying, the members still waiting are short. Whether the banker covers the gap depends on what was agreed.
• Banker risk. All the money passes through one person. If they lose it, spend it or disappear, the group has little to fall back on.
• Inflation. The pot returns the same number of dollars you put in, so it earns nothing and buys a little less if prices rise.
• Pressure. Borrowing to keep up payments, or joining several groups at once, can leave you short for rent and bills.

Sou-sou or pyramid scheme?

In August 2020 the Trinidad and Tobago Securities and Exchange Commission, the Financial Intelligence Unit and the Central Bank issued a joint public advisory on this question. In their description, a genuine sou-sou does not depend on recruiting new members and is not run for profit, while a pyramid scheme depends on a steady stream of new recruits to pay earlier ones. Pyramid schemes are often dressed up as sou-sou or as investments. Warning signs the advisory lists include:

• You pay in to receive a much larger payout later.
• Payouts depend on bringing in new members, and early members are paid with newer members’ money.
• You are pushed to recruit others so you can reach higher “levels” or “circles”.
• It promises unusually high cash returns outside any regulated channel.

The name does not matter. If the money you receive depends on other people joining after you, it is not a sou-sou. Do not pay, and report suspected fraud to the Trinidad and Tobago Police Service Fraud Squad. Our Scam Watch page shows how these collapse.

Making one safer

• Join people you know and trust, and know who the banker is and where they live and work.
• Write the rules down: amount, dates, order, late payments, what happens if someone leaves, and whether the banker charges a fee.
• Pay by bank transfer or another traceable method and keep the receipts, so there is a record if there is a dispute.
• Share the list so every member can see who has been paid.
• Only put in what you could afford to lose, and never use your emergency fund or borrowed money to join.
• If you do not need the lump sum yet, a late hand is fairer to the group, though it carries more waiting risk for you.
