Documented cause
Tuza Finance offered digital working capital loans to Rwandan SMEs using invoice financing and mobile money data. Founded by Diane Uwimana in Kigali, the startup raised $600,000 in seed funding in 2021 from two East African venture funds. Tuza grew to 1,200 SME borrowers by 2023 but faced severe concentration risk: 40% of its loan book was held by businesses in the hospitality sector. Rwanda's hospitality sector downturn following post-COVID tourism recovery delays pushed NPLs above 38% by Q2 2023. A bridge loan from one investor fell through in November 2023, and Tuza Finance ceased new lending in January 2024 before formally winding down in April 2024.
Lesson
“SME lenders must enforce hard sector concentration limits — a single industry downturn should never be able to destroy the entire loan book.”
