Problem
African banks' cost-to-income ratios are 20 points above global peers
Retail and commercial banks with CTI ratios above 60%, particularly those with 50+ branch networks
Branch networks built for a cash economy haven't adapted to digital payments. Back-office processes designed 20 years ago run on paper and Excel. Staff costs consume 45% of revenue.
Every percentage point reduction in CTI translates to $2–5M in annual profit for a mid-sized bank. Banks above 60% CTI will be acquisition targets by 2028.
The average cost-to-income ratio for Sub-Saharan African banks sits at 65%, versus 45% for global best-in-class. Branch-heavy models, manual processes, and low digital adoption drive unsustainable economics.
