A Bank in Every Pocket

2007 CE

History · Contemporary · Holocene · Meghalayan

In 2007, the year the smartphone launched in California, a plainer revolution began in Kenya: M-PESA, money stored on a phone and sent by text. It reached most Kenyan households within a decade and its effects have been measured like a clinical trial: higher consumption, two percent of households lifted from poverty, women moving from farm work into business. The phone, not the bank branch, became the developing world's financial infrastructure.

Why it matters

By the 2010s, more humans had access to a mobile phone than to a toilet: the fastest adoption of any technology in the species' history, and its most egalitarian. Mobile money shows what that reach does when it meets a real constraint, the inability to save, send and borrow, and it leapfrogged a century of banking infrastructure in a decade. The next billion people online will meet the world's knowledge, markets and manipulations through a device in their palm.

Dating & uncertainty

M-PESA launched in Kenya in 2007, letting value move by text message; adoption reached the vast majority of Kenyan households within a decade. The measured effects give the anchor its weight: access to mobile money raised consumption and lifted an estimated 2 percent of Kenyan households out of poverty, with the strongest gains for households headed by women.
