Something people should be more aware of regarding Kiva... Ignore the pictures of the people you are purportedly lending to, their projects, and even their country. That is pure marketing. If you read the small-print http://www.kiva.org/about/how/even-more you will see that you aren't lending to these people at all, but actually making zero-interest, low-risk, short-term loans to micro-finance institutions. (That sai…
That's not quite true is it - if that person defaults you lose your money. It's similar to switching electricity suppliers (stay with me!) - you don't get a new cable straight from the electricity company which carries only "their" electricity, you stick with the same cable and the same electricity but more of your supplier's electricity gets bought.
Actually, it's your assertion that is not quite true.
It certainly used to be the case that "We give Field Partners the option to cover [...] entrepreneur defaults." [1] And there was indeed evidence at the time that Field Partners were doing just that. [2]
Although they have removed this explicit wording, it isn't clear that doing this is no longer allowed, and there is some evidence that the practice is continuing: Only 7 out of 128 pilot or active Field Partners report a default rate of more than 1%; indeed, around three-quarters of them report a default rate of 0.00%. [3] Frankly, these statistics are unbelievable unless we accept that most Field Partners still cover entrepreneur defaults.
So if the end-borrower defaults, you might lose money. But rather more likely is that the Field Partner will cover the loss themselves as an operating cost, not report any of this to Kiva, and you will be none-the-wiser.
