The Economist Intelligence Unit report published Thursday offers a conservative scenario that banking in 16 African economies will boost assets by 178 percent to $980 billion by 2020.

“A more likely scenario” has assets expanding to $1.37 trillion.

The boom is forecast on high economic growth, application of technology and inclusion of the unbanking majority.

Angola is slated to lead with a projected fivefold increase.

Countries including Ghana, Tanzania and Uganda are expected to triple banking assets. Well-developed banking sectors in South Africa, Namibia and Botswana can expect slower growth.
