How Rotating Savings Circles Turn Trust Into Lump Sums for People Who Cannot Save Alone

This page is for education and discussion. It is not financial or legal advice.

A rotating savings circle is a small group of people who each pay the same amount into a shared pot on a set schedule, and each time one member takes the whole pot home. When every member has had a turn, the circle ends or starts again. The idea is very old and very widespread, and it carries a surprising lesson: for many people, saving is a group skill, not a private virtue. This page matters for solving problems in living because it describes a tool that people who cannot save on their own have used for generations to buy a sewing machine, pay a deposit, or survive a bad month. It also matters for the move from scarcity toward abundance. Savings circles show that trust between ordinary people can stand in for money a household does not yet have, and that same trust is what any semi-private basic income built on credit unions and nonprofits would depend on.

Economists call these groups rotating savings and credit associations, often shortened to ROSCAs. People know them by many local names, such as tandas, susus, and chit funds.

How a savings circle works

Imagine ten people who each agree to pay 100 dollars a month. Each month the pot holds 1,000 dollars, and one member receives it. After ten months, everyone has paid in 1,000 dollars and taken out 1,000 dollars.

Nobody earns interest, so why bother? The answer is timing. The first person to receive the pot gets a 1,000 dollar interest-free loan, repaid through the next nine payments. The last person gets a forced savings plan that delivers a lump sum on a known date. Everyone in between gets something of both. In a 1993 paper in the American Economic Review, Timothy Besley, Stephen Coate, and Glenn Loury modeled exactly this. They showed that people who save for a large, indivisible purchase and lack access to credit markets can all end up better off in a ROSCA than saving alone, because on average members get the item sooner.

Circles decide the order in different ways. Some draw lots, some rotate by agreement or need, and some let members bid for an early turn. Besley, Coate, and Loury found that when members have similar tastes, a random draw tends to work better than bidding, though that result can change when members differ a great deal.

Why people who cannot save alone can save together

The standard story says that people with low incomes do not save because they have nothing left over. Real life is messier. Money that sits in a drawer or a checking account is under constant pressure: a relative asks for help, a child needs shoes, a small treat feels deserved after a hard week. Each draw on the money makes sense on its own, and together they empty the account.

Mary Kay Gugerty studied 70 ROSCAs in western Kenya and published her findings in 2007 in Economic Development and Cultural Change. She found support for a commitment explanation: many members join because a public promise to a group protects their savings from themselves and from the people around them. Members she interviewed often put it simply. One cannot save alone. The group turns a private intention into a social obligation, and that obligation is much harder to break than a resolution made in the shower.

This reframes a common problem in living. A person who keeps failing to build savings is often described as lacking discipline. The ROSCA evidence suggests a better description: that person lacks a structure. Supply the structure, and the same person often saves reliably.

Savings circles in the United States

ROSCAs are most common in lower income countries, but they are also used in the United States, especially by immigrant communities. Besley, Coate, and Loury noted that many early American savings and loan associations appear to have started life as rotating savings groups, which means part of the formal banking system grew out of this informal practice.

A modern example is the Lending Circles program run by Mission Asset Fund, a San Francisco nonprofit. It keeps the basic circle but adds a twist: payments are reported to the credit bureaus, so on-time contributions build a credit history. A 2013 evaluation by researchers at San Francisco State University compared 260 participants with a matched comparison group of 383 people. Participants raised their credit scores by an average of 168 points, reaching an average of 603, and the gains were largest among people who started with no score or a thin credit file. Participants also cut their outstanding debt, while the comparison group added debt during the same period.

A 2020 discussion paper from the Federal Reserve Bank of Philadelphia reviewed the program. It reported that, as of January 2019, Mission Asset Fund had facilitated about 10 million dollars in loans to more than 10,000 clients, and that the share of its circles reported as 90 days or more past due was half the rate of a standard consumer credit default index.

Why this matters becomes clear against the national picture. The Federal Reserve's survey of household finances for 2024 found that only 63 percent of adults would cover a sudden 400 dollar expense with cash or its equivalent, and 13 percent said they could not pay it by any means. For the 37 percent who would not, a circle can be a bridge between having nothing set aside and having a cushion.

Where savings circles fail

Savings circles run on trust, and trust can break. The member who receives the pot early has an obvious reason to stop paying. Siwan Anderson, Jean-Marie Baland, and Karl Ove Moene studied this enforcement problem and published their work in the Journal of Development Economics in 2009. They showed that, without some form of social sanction, a ROSCA cannot sustain itself even if a defaulter is excluded from all future circles. They also argued, using evidence from groups in a Kenyan slum, that careful design of the circle itself can reduce the risk.

Other honest limits are worth stating:

A circle pays no interest, so for a person who already saves easily, it can cost something in lost returns.
A defaulting member can leave the others short, and an informal circle offers no deposit insurance.
Friendship and family ties can be strained when someone cannot pay.
Circles organized by strangers, especially online, carry a real risk of fraud. A formal program that reports to credit bureaus adds structure but also adds paperwork and data sharing.
A circle moves money around a group. It does not create new income, so it cannot replace a living wage or a basic income.

What savings circles teach about abundance

The deeper lesson is about where scarcity sits. In a savings circle, nobody has more money at the end than they put in, yet most members are better off, because each gets a lump sum sooner or more reliably than saving alone would allow. The scarce resource was never only money. It was trusted structure: a group that keeps its promises and a schedule that protects savings from daily pressure.

That points toward a design idea for basic income delivered semi-privately. Credit unions and community nonprofits already know how to run small, trust-based financial products. A modest regular payment could be paired with an optional savings circle, so that people who receive income also gain a social commitment device and a credit history. Digital tools, including censorship-resistant payment systems, could someday let circles run across borders without a single gatekeeper, though the enforcement problem described above would follow them there.
