Tontine is one of the most ingenious and resilient economic institutions in sub-Saharan Africa. Its confrontation with the formal banking system reveals deep tensions over what it means « financial development » And for whom.
Tontine as a masterpiece of social engineering
Tontine elegantly solves problems that the formal banking system cannot solve: it creates interest-free forced savings, distributes credit without formal guarantees, includes people that the banking system excludes, and works on interpersonal trust rather than contracts. It is resilient because it is rooted in real social relations.
Formalisation as Standardisation
When a tontine formalizes, it gains legal certainty but it loses its original nature. Banking management fees smear margins. Audit requirements exclude the most vulnerable members. Interpersonal trust is replaced by contracts that nobody really reads. Formalisation does not always improve the service — It turns him into something different.
Promising hybrid models
Experiences in Kenya, Rwanda and Senegal show that it is possible to digitise tontines without fully formalising them: mobile applications allow to manage contributions, trace flows, access microcredits — while preserving community governance and informal inclusion.
The real question is not bank or tontine. It's: how to preserve the social intelligence of tontine while accessing the tools of the modern world?
