Informal savings and lending groups and financial inclusion in Zambia: Evidence from a desk review

Abstract

This paper analyzes informal savings and lending mechanisms in Zambia, highlighting their roles in promoting financial inclusion, consolidating member risks, and emphasizing the need for a pragmatic policy response. A literature review conducted from a desk for the years 2015–2025, using peer-reviewed studies and relevant institutional and grey literature sourced from Google Scholar, JSTOR, the University of Zambia repository, and selected institutional websites. The review integrates data from Village Savings and Loan Associations (VSLAs), village banking groups, Savings and Internal Lending Communities (SILCs), Accumulating Savings and Credit Associations (ASCAs), Rotating Savings and Credit Associations (ROSCAs), Savings and Credit Cooperatives (SACCOs), and specific informal credit systems such as kaloba and OSAWE. It looks at their structures, the types of people who are members, how they run their businesses, how they are governed, the benefits and drawbacks, and the results that have been reported. The review shows that these mechanisms are still the main ways that low-income and informal households save money, get small loans, smooth out their spending, help microenterprise activities, and deal with unexpected shocks. They work well because they have simple, locally enforceable rules, peer accountability, and governance structures based on trust. Women consistently participate in all mechanisms, and the results include better household welfare, stronger social networks, better financial discipline, and a greater ability to handle liquidity constraints. At the same time, all models show that there are structural problems that keep coming up. These include a lack of capital pools, poor record-keeping, a concentration of leadership, a lack of transparency in loan approval processes, and inconsistent consumer protection practices. In arrangements that are linked to the outside world or based on guarantees, members' risk exposure goes up when joint liability mechanisms, outside credit injections, or a lack of documentation make them more vulnerable. The quality of evidence differs among provinces and mechanisms, and significant concepts like "village banking" and "sustainability" lack consistent definitions across sources. These inconsistencies make it harder to compare things and make it harder to understand policies. The synthesis shows that informal ways of saving and lending money can't be put into one group. The structure of an institution affects how strong its governance is, how long it can last, and how much risk it puts on its members. Member-funded, savings-led arrangements usually have lower systemic risk, but they are still at risk when governance and documentation systems are weak. When there aren't enough oversight mechanisms, externally linked or semi-formal arrangements can make things more complicated and less stable. The paper posits that a policy approach that is balanced, fair, and based on risk is needed. Informal savings groups should not be subject to the same regulations as formal banks. Instead, policymakers may want to focus on making internal governance practices stronger, improving basic record systems, making typologies clearer, and giving people safe, voluntary ways to interact with formal financial institutions when it's appropriate. Regulatory overreach may limit access for underserved populations, whereas regulatory neglect may subject members to avoidable harm. The paper turns institutional differences into useful policy priorities that support long-term and inclusive financial growth by putting together scattered Zambian evidence into a structured comparative synthesis.
