Earlier we highlighted how India is learning mobile banking from Kenya. Recently the Economist said, “Paying for a taxi ride using your mobile phone is easier in Nairobi than it is in New York, thanks to Kenya’s world-leading mobile-money system, M-PESA.” This world-leading mobile-money system of Kenya is a great example of unintended consequence. It had several factors in its favour, including the exceptionally high cost of sending money by other methods; the dominant market position of Safaricom; the regulator’s initial decision to allow the scheme to proceed on an experimental basis, without formal approval; a clear and effective marketing campaign (“Send money home”); an efficient system to move cash around behind the scenes; and, most intriguingly, the post-election violence in the country in early 2008. M-PESA was used to transfer money to people trapped in Nairobi’s slums at the time, and some Kenyans regarded M-PESA as a safer place to store their money than the banks, which were entangled in ethnic disputes.
