What happened
In March 2007 the Kenyan mobile operator Safaricom, then majority-owned by Vodafone, launched M-Pesa, a service that let people store money as value on their mobile phone SIM cards and send it to others by text message. Customers handed cash to a local agent, who credited their phone with electronic funds; they could then transfer that money by SMS to anyone else, who withdrew it as cash from their own nearby agent. The service had originally been designed to help microfinance customers repay loans, but pilot users were instead sending money to relatives and paying for goods, so the team relaunched it as a person-to-person money transfer product. In a country where most adults had no bank account, uptake was extraordinarily fast, reaching about 2 million customers within a year, and M-Pesa built a network of agents that vastly outnumbered the country's bank branches and cash machines.
Why it matters
M-Pesa showed that a poor country could leapfrog traditional bank branches entirely and deliver everyday financial services over basic mobile phones. A study by economists published in Science found that access to M-Pesa lifted an estimated 186,000 Kenyan households, about 2 percent of the total, out of poverty, with an outsized effect on female-headed households. It became the template for mobile money across Africa and much of the developing world, a demonstration that the future of money for billions of people might run through phones rather than banks.
How we know
M-Pesa's launch date and early growth are documented by its operators, Safaricom and Vodafone, and its poverty impact was measured by economists who surveyed thousands of Kenyan households over six years and published their peer-reviewed findings in the journal Science.
