I also think that this is a good idea. Clearly, some investors are more concerned about repayment. Having a better sense of the operational track record of the MFI listing the loan could help lenders match themselves with thier comfortable risk levels. And repayments are the heart of loan programs. There is something amiss when they get too far in arrears. This isn't good for the program, the clients, or the borrowers waiting in the wings. Matt Flannery, one of the co-founders of Kiva has a blog. He recently posted a letter that arrived in their offices from a Kiva friend that visited Kenya and sought out Ebony to see what they were doing. It puts any failings in an arresting context. Here's the link:
http://www.socialedge.org/blogs/kiva-chronicles/archive/2006/11 Shelby Clark is presently volunteering as a field rep for Kiva with an MFI in Uganda that has temporarily suspended making new loans until they can improve the repayment rate on the present ones. (He has a blog, too.) Here's one of the clients he described meeting: "Also, I met a guy, and when I went to shake his hand he gave me a hug instead. This guy is HIV positive, and I strongly believe that without his loan he would have died by now. When he first got the loan last June, he was incredibly sick (started at ~130 lbs before getting sick, and dropped to 80 lbs !!!!!! after getting sick), and could barely walk. All of his money went to his medication, transport to health care, and feeding his 9 children (8 of his own and an orphan of his brother's, who died of AIDS). Once he got the loan he was able to spend some money on goods to sell (supplies for an Ox plow), and now has enough income to take care of his illness, eat properly, support his kids, and even send some of them to school. He's since regained weight and weighs about 115 lbs, and can now walk with the help of a cane. He attributes most of the improvements in his life to his microloan."
When I read stories likes these, I understand why some borrowers may be struggling with repayment schedules. I'm certain there is a significant portion of lenders who would be willing to loan anyway, if the conditions were made clear, up front.
But letting lenders have resonable expectations would serve Kiva. Should there be a special class of loans for borrows in extraordinarily difficult circumstances, like those suffering from AIDS if a ranking system is adopted? I'd hate to think MFI's became reluctant to lend to these people to protect thier rating.
Perhaps that's why there isn't a rating system. I think I've just talked (typed?) myself out of this idea.
