Of adults in sub-Saharan Africa owned a financial account in 2024, up from 49% in 2021.
World Bank · Global Findex 2025 release ↗Data scope: World Bank Global Findex 2025. Account ownership includes mobile money and does not establish active use, affordable credit or service reliability.
What the evidence tells us
The World Bank reports growing account ownership and exceptionally widespread mobile-money use in sub-Saharan Africa. The remaining research problem is broader than opening accounts: people need services they can understand and use consistently. Household survey indicators should be complemented by operational evidence when studying failed transactions.
Read the underlying source ↗Axum’s research and commercialisation agenda
Axum proposes practical tools for informal enterprises and people who need assisted access. Discovery should examine the causes of recordkeeping errors or failed transactions before choosing a technology. A commercial product should demonstrate sustained usefulness at a cost its intended customers can afford.
These are proposed research directions. Patentability and commercial viability remain to be established for each invention.
