Here's the 02/01/08 update to my late loan statistics charts.
These charts show statistics for the performance of ALL prosper.com loans. Each curve represents the set of loans that were created in one calendar month. The vertical axis is the fraction of those loans that have "gone bad", in other words are 1 month late or worse (up to and including default). The horizontal axis is the observation date. All data comes from Prosper.com's performance web page.
A larger, more readable version of that chart can be found here
Nothing much new. Loans continue to go bad at about 20% per year.
