Financial technology investors are calling for policies that promote development to achieve the World Bank target of universal financial access by 2020. Financial experts who attended the Africa Payments Innovation Summit in Nairobi said digital disruption could increase the continent's banked population. The emergence of mobile money services over the past decade has contributed to financial inclusion in Africa. According to the mobile operators association GSMA, there were 277 million registered mobile money accounts in sub-Saharan Africa at the end of 2016. But despite the progress, at least 85% of transactions in the region are still in cash. There is a mistrust between banks and telcos about whose customer they are serving, who owns the infrastructure, and the loading of additional costs on transactions between the two. Central Bank of Kenya Governor Patrick Njoroge warned innovators against getting carried away by technology.
