I’ve just finished teaching a course at Boulder on the use of branchless banking channels and technology to reduce transaction costs. This was well-attended; the four-day, 10-hour course had 39 students, and a shortened single day, two-hour version had 20 students.

We had a very interesting class discussion on whether group loan repayments through branchless banking channels would undermine the group ethos, and there was surprising consensus in that it need not. Another much discussed topic was how to balance cash in and cash out at the agents, and how to promote savings on the back of electronic payments.

In terms of use of agents for deposit-taking, we know there is a very fundamental business model problem. Agents are used to taking something like 10% commission on selling a coke bottle, a mobile prepaid card, etc. So why would they do cash in/out for much less than 10% commission if that saddles them with extra security risks and extra trips to the bank? And with that sort of commission level, microsavings are dead. There are several answers to this:

• The practical solution happening out there: agents are used mostly for special transactions where someone is prepared to give them extra commission: mobile prepaid cards, international remittance termination, bill payment (if the utility wants to get out of collecting itself). But there is very little traction on savings.
• The purist solution: use product portfolio and marketing levers to balance cash in and cash out at the village level. Agents can then manage local liquidity as a ‘closed loop.’ This would need to work community by community, and there could be no universal answers. It would have more chance of working if branchless banking was a tool managed and used by local microfinance institutions with the required level of grassroots presence and understanding. But in my view it can’t work so long as branchless banking is the preserve of the larger banks and telecom operators, as today.
• Take the agent business out of stores. This gets away from high overhead and higher opportunity costs. Combine the susu collector with Wizzkids: roving people in market stalls, going door-to-door, etc., offering to buy and sell cash for electronic value. This way, you turn the agent problem into a livelihood activity.
• The shock solution: go for total cash substitution. Eliminate cash and you eliminate the cash in/out problem. Radical, but something that one colleague said could perhaps see traction in conflict areas. The security aspect can then be a powerful driver for eradicating cash by having clients express preference for electronic over cash payments.

The general feeling was one of excitement at the potential, but a realization that these channels will, at least for a while, be dominated by larger banks and mobile operators who have the wherewithal to invest in this area. MFIs should seek to share in their infrastructure rather than to try to create their own, knowing that interoperability will take a while to develop — just as it did for ATMs and POSs.
