Summary
Banks use statistical models to predict loan default risk. This study extends these models for installment loans, focusing on assessing total loss distributions for insurance purposes.
Area of Science:
- Quantitative Finance
- Risk Management
- Statistical Modeling
Background:
- Banks accumulate vast datasets for customer behavior analysis.
- Credit risk assessment and loan default prediction are critical banking issues.
- Stochastic models are increasingly used for credit risk management.
Purpose of the Study:
- To analyze and extend existing stochastic models for credit risk.
- To adapt models for loans repaid in installments.
- To determine the probability distribution of total losses from loan defaults for insurance.
Main Methods:
- Review and analysis of two major industry-standard stochastic models for loan default.
- Exploration of model extensions for installment loan repayment scenarios.
- Modeling default times as a discrete-time survival distribution.
Main Results:
- The study provides methods to extend current credit risk models to installment loans.
- It focuses on calculating the probability distribution of total losses.
- The research facilitates the assessment of probabilities for significant financial losses.
Conclusions:
- The developed approaches enhance the application of stochastic models in banking.
- Accurate assessment of loss distributions is crucial for insurance and risk mitigation.
- This work contributes to better understanding and managing credit risk in financial institutions.
