Social lending service Kiva has refined its risk assessment for participating MRIs (microfinance institutions). The changes and the mechanism are described here. Risks for Kiva lenders include Entrepreneur Risk, Fieldpartner Risk and County Risk. 

So far the default rate for Kiva has been 0.17% on a loan volume of $9.965.000 (4.4% of loans are one month late). When compared to Prosper.com default rates, that is an extremly good result. So far the MRI on Kiva with the worst performance is REDC Bulgaria, followed by an MRI that organizes loans to people in Uganda, Kenya and Tanzania.

Another interesting figure: The average time a listing is online at Kiva.org until it is fully funded is 1.24 days.

So far all my Kiva loans are repaying on schedule.
