Rotating Savings and Credit Associations (ROSCA) is a widely used financial tool in developing economies that is quite unfamiliar to many affluent groups in the West.

This concept is somewhat similar to the game Monopoly — each participant can create their own rule variations, but the core logic remains consistent:

A group of people contribute funds to a common pool regularly. In turn, each member can receive the total accumulated amount of the pool. This mechanism cleverly combines savings discipline with access to credit, especially in areas where traditional banking systems are imperfect or difficult to access. ROSCA is essentially decentralized, driven by mutual trust among participants — which is why it has remained viable for hundreds of years in communities without formal financial infrastructure.
