Loan Credit GradeThe way Lending Club calculates loan credit grade and interest rate has been constantly evolving for past five years. Lending Club provides detailed information on method for setting the Interest Rate and Loan Grade for each loan. It appears from my analysis, Lending Club continues to tweak interest rates and underlying dependencies especially for lower quality loans. Before I review the relationship of Loan Grade with Interest Rate, let's look at Loan Grade with Loan Issued Date and Loan Listing Date.
Loan VolumeAs the chart below shows, more than 50% of loans issued every year are categorized as top two best grades; Credit Grade A and B. The volume of loans of all credit grades has been growing at spectacular rate, year over year. However, only 1,301 and 377 loans were issued with Credit Grade F and G respectively in past five years. It is difficult to build a diversified portfolio (800+ loans) solely from grade F and G grade loans that carry high interest rates due to low volume of such loans.
Default RateAs the chart below shows, the number of loans with charged-off and default status increases with the credit grade, from A to G, for loans issued each year. The trend is similar to the ones shown in my previous post Lending Club Loan Interest Rate and Return - Do Defaults Matter?. While the default rate and interest rate bin relationship was much more consistent, that is not the case with loan credit grade. The relationship with loan credit grade is only consistent for better quality loans, those with credit grade A to D.
Days between Loan Listing and Issued DateA reader 'Learner' commented on Peter's blog post Every P2P Loan is Getting Funded at Lending Club:
"The more creditworthy the loan, the longer it will take to fund."As I was preparing to analyze the data for Loan Credit Grade with respect to the Number of Days between Loan Listing and Issued Date, I became curious to find out if the above quote holds true for loans with different Credit Grade. Do higher quality Grade A and B loans take longer to be issued after listing? I don't have the date when funding for a loan completed so I can't directly analyze the days it takes a loan to be fully funded. However, days between loan listing and issued date for a loan offers a close proxy.
The chart below shows the number of loans of a specific grade issued as a function of number of days between listing and issued date for the loans.
The chart below shows the percentage of loans of each grade that have Charged Off and Default status as a function of number of days between listing and issued date of loans. In general, the default rate is higher for loans as the days from listing to issue loans increases. The exceptions are the loans issued within two days of listing and lower quality loan grades. I suspect these exceptions have more to do with fewer number of loans and data points for loans issued within two days of listings and in lower quality loan grades.
- To build a high return diversified portfolio, investment need to be made in all or most lower quality loans listed on Lending Club platform at much higher risk.
There is no evidence from above analysis that better quality loans take longer to be issued. The lower quality loans, in spite of higher interest rates and small volume, are either not in much demand or take too long to be issued by Lending Club after being fully funded. Update July 6, 2012: This takeaway may not be correct due to error in interpreting how Tableau calculates quartiles.
Leigh Drogen at Surfview Capital recently published an interesting article Complete Lending Disruption. He writes "Lending is about to be taken out of the hands of the banks, and put into the hands of the average person." I couldn't agree more. Worth a quick read.
