We’ve written previously about the potential of mobile banking to help marginalized populations overcome poverty’s debilitating effects. Elsewhere, you can find extensive data on the enormous financial potential of mobile banking. Indeed, the alignment of corporate and development interests in the sector suggests a sustainable, double bottom-line opportunity.

Through strategic cooperation, mobile operators, governments, and financial experts can each achieve their respective goals — profit for the former, improved livelihoods for the latter two — and empower the poor to securely save, better manage day-to-day risk, and seize new opportunities to improve their lives.

The birthplace of both paper money and Maoism, China has a long, complex history with capital. Known for both the novelty and the sophistication with which it has managed its resources — from shells to bronze coins to ‘socialism with Chinese characteristics’ — China recognized early on that value, once tangibly captured and fungible, holds immense power in shaping and moving society.

Today, China is poised to begin another era of financial innovation. In October 2010, state-owned China Mobile — the world’s largest mobile network operator — acquired a 20 percent stake in the Shanghai Pudong Development Bank, also government controlled. The operator is expected to launch a range of mobile financial services (MFS) nationally this year, and industry watchers predict a dramatic take-off in mobile payments in the near-term. Given that progress in mobile banking across markets is often stifled by inefficiencies between regulator, operator, and service provider, China’s integration of the three is intriguing and opens up new possibilities. In addition, with mobile penetration high (64 percent and growing) and bank card penetration relatively low, as well as accumulated experience from various recent pilots, 2011 indeed looks promising for MFS growth in China.

One presentation that perked my ears at the recent Columbia Institute for Tele-Information’s Mobile Money II Conference was by Judith Mariscal of CIDE, a Mexican social science research centre. In examining literature on mobile money vis-a-vis data from select deployments, Mariscal and research partner Ernesto M Flores-Roux found that many of mobile banking’s accepted maxims don’t always hold. Their resulting “The Enigma of Mobile Money” [presentation and paper], which Mariscal presented at Mobile Money II, thus tempers the oft breathless enthusiasm for mobile as holy grail for the poor and unbanked.

To date, we’ve seen relatively few mobile banking home runs — currently, of nearly 100 deployments worldwide, only 10 can claim over one million users — thus, Mariscal noted, our understanding of what it takes to succeed in mobile banking is patchy at best and a more critical eye towards industry truisms is warranted. Some common myths addressed by Mariscal and Flores-Roux:

Many of the world’s poorest live without access to basic banking services such as savings, insurance, payment services, and basic credit. Those in the developed world often take these services for granted without realizing their contributions to secure, productive livelihoods. Savings allow us to decrease our risk in handling cash and insurance allows us to protect against economic shocks; payment services allow us to save time that can be spent in more productive ways and basic credit allows us to use current assets to capitalize on future opportunities.

Half the global population, however, lives without such services, or at least without such services as enjoyed by the majority of the developed world. The percentage of households that are financially excluded increases to 80 percent when looking at Africa. Traditionally unattractive to commercial banks, low-income populations are forced to seek out alternative service providers, often at great financial burden and opportunity cost to themselves.
