Market Size
Tanda or Rosca?
The market for people participating in Rotating Savings and Credit Associations (ROSCAs), also known as tandas or by various other names worldwide, is substantial:
1. Global value: ROSCAs amount to more than $500 billion in value raised worldwide[3].
2. Prevalence: ROSCAs are highly popular in developing countries, with membership rates reaching up to 95% in several African nations such as the Republic of Congo, Cameroon, Gambia, Ivory Coast, Togo, and Nigeria[4].
3. Regional examples:
- Brazil: Over 7 million people use "consorcios," a form of ROSCA 2.0 administered by financial institutions[1].
- Egypt: MoneyFellows, a digital ROSCA platform, serves more than 4 million users[4].
- Indonesia: Mapan, a ROSCA-based fintech, has around 3 million users[4].
4. Developed markets: While ROSCAs are more common in developing countries, there's growing interest in developed markets. For example, digital platforms are emerging in the United States and the United Kingdom to serve immigrant communities and others interested in this financial model[5].
Given the widespread nature of ROSCAs across different cultures and the increasing digitalization of these systems, the total number of participants worldwide likely reaches into the hundreds of millions. The market size is significant and continues to grow as fintech companies innovate to bring this traditional financial practice into the digital age.
