This, he said, could be achieved through the commercial and Small and Medium Enterprise sector if they focus on reaching the highly untapped mass market.
Mr Wessels, who was interacting with journalists in Accra on Friday, said findings from a study by RBSC had shown that about $60 billion could be mobilised from more than 400 million low earners each year in sub-Saharan Africa.
He said: “Commercial banks can win millions of new customers in Africa by using integrated strategies for the mass market, especially as four out of five adults in Ghana, Tanzania, Kenya, Nigeria and other sub-Saharan African countries either have no access to banking services or prefer informal alternatives. This amounts to (more than) 400 million people who represent untapped potential for banks.”
