ListenData: Datasets for Credit Risk Modeling

This tutorial outlines several free publicly available datasets which can be used for credit risk modeling. In banking world, credit risk is a critical business vertical which makes sure that bank has sufficient capital to protect depositors from credit, market and operational risks. During the process, its role is to work for bank in compliance to central bank regulations.

Important Credit Risk Modeling Projects

1. Probability of Default (PD) tells us the likelihood that a borrower will default on the debt (loan or credit card). In simple words, it returns the expected probability of customers fail to repay the loan.
2. Loss Given Default (LGD) is a proportion of the total exposure when borrower defaults. It is calculated by (1 - Recovery Rate). For example someone takes $200,000 loan from bank for purchase of flat. He/She paid some installments before he stopped paying installments further. When he defaults, loan has an outstanding balance of $100,000. Bank took possession of flat and was able to sell it for $90,000. Net loss to the bank is $10,000 which is 100,000-90,000, and the LGD is 10% i.e. $10,000/$100,000.
3. Exposure at Default (EAD) is the amount that the borrower has to pay the bank at the time of default. In the above example shown in LGD, outstanding balance of $100,000 is EAD

Datasets for Credit Risk Modeling Projects

We have gathered data from several sources. See the list below. The following websites own the copyright on these data and authorizes their reproduction.

1. Kaggle
2. UCI Machine Learning Repository
3. Econometric Analysis Book by William H. Greene
4. Credit scoring and its applications Book by Lyn C. Thomas
5. Credit Risk Analytics Book by Harald, Daniel and Bart
6. Lending Club
7. PAKDD 2009 Data Mining Competition, organized by NeuroTech Ltd. and Center for Informatics of the Federal University of Pernambuco

It includes variables from different sources which are required to build robust and accurate probability of default model.

• Credit bureau variables which contains details about borrower's previous credits provided by other banks
• Previous Loans that the applicant had with Home Credit
• Previous Point of sales and cash loans that the applicant had with Home Credit
• Previous Credit Cards that the applicant had with Home Credit

This book has credit card data which comprises of target variable which is binary in nature (1 if application for credit card accepted, 0 if not) and a few independent variables about demographics and credit history of credit card holders.

Dataset about credit card defaults in Taiwan contains several attributes or characters which can be leveraged to test various machine learning algorithms for building credit scorecard.
Note : Poland dataset contains information about attributes of companies rather than retail customers.

It is a credit card application data of Brazilian customers. It has a labeled data set from one year period for training credit scoring model. You can do scoring to the leaderboard dataset from one year later. To download data, clink on this link Download Data and then click on Download button.
