How has mobile banking stimulated financial development in Africa?

In the first empirical assessment of the incidence of mobile banking on financial intermediary development in Africa, we use two definitions of the financial system: the traditional IFS (2008) and Asongu (2011) measures of financial sector importance. When the conception of a financial system is based only on banks and other financial institution (IFS, 2008), mobile banking has a negative incidence on traditional financial intermediary dynamics of depth, activity and size. However, when a previously missing informal-financial sector component is integrated into the definition (Asongu, 2011), mobile-banking has a positive incidence on informal financial intermediary development. Three major implications result from the findings. (1) There is a growing role of informal finance in developing countries. (2) The incidence of the burgeoning phenomenon of mobile-banking cannot be effectively assessed at a macroeconomic level by traditional financial development indicators. (3) It is a wake-up call for scholarly research on informal financial intermediary development indicators which will oriented monetary policy; since a great chunk of the monetary base(M0) in less developed countries is now captured by mobile-banking.
