Credit risk terminology encompasses various concepts related to the potential for financial loss due to a borrower’s failure to repay a loan or meet contractual obligations. Here are some key terms:
1. Credit Risk Modeling
Credit risk modeling refers to the process of quantifying and managing the risk of loss due to a borrower’s failure to make loan payments or meet contractual obligations. It involves developing statistical models and techniques to assess the creditworthiness of borrowers and estimate the potential losses associated with lending activities.
2. Importance of Credit Risk in Banks
Credit risk is a significant concern for banks as a substantial portion of their assets consists of loans and credit products. Effective credit risk management is crucial for maintaining financial stability, minimizing loan losses, and ensuring profitability. Inadequate credit risk management can lead to significant losses and even insolvency.
3. How the loss is calculated using Credit Risk?
Credit risk models typically estimate potential losses by considering three main components: Probability of Default (PD), Loss Given Default (LGD), and Exposure at Default (EAD). These components are combined to calculate the Expected Loss (EL), which represents the estimated average loss on a loan or portfolio.
4. PD (Probability of Default) Model
The PD model estimates the likelihood that a borrower will default on their loan obligations over a specific time horizon. It considers various factors such as credit history, financial ratios, macroeconomic conditions, and industry trends to predict the probability of default.
5. LGD (Loss Given Default) Model
The LGD model estimates the percentage of the exposure that the lender expects to lose if the borrower defaults. It considers factors such as the collateral value, recovery rates, and the lender’s ability to mitigate losses through collection efforts or asset liquidation.
6. EAD (Exposure at Default) model
The EAD model estimates the outstanding loan balance or exposure that the lender will face in the event of a borrower’s default. It takes into account factors such as the loan amount, credit lines, and potential future drawdowns.
7. Credit Limit, Asset Financing, Credit Risk, Default Event, Risk-based Pricing
- Credit Limit: The maximum amount of credit a lender is willing to extend to a borrower.
- Asset Financing: Lending activities involving the provision of funds for the acquisition of assets, such as mortgages or equipment financing.
- Credit Risk: The risk of loss due to a borrower’s failure to meet their loan obligations.
- Default Event: The occurrence of a borrower failing to make scheduled loan payments or violating loan covenants.
- Risk-based Pricing: The practice of adjusting loan pricing (interest rates, fees) based on the assessed credit risk of the borrower.
8. Expected Loss and its components PD, LGD, and EAD
Expected Loss (EL) is a measure of the average credit loss a lender can expect to experience on a loan or portfolio. It is calculated as the product of three components: Probability of Default (PD), Loss Given Default (LGD), and Exposure at Default (EAD).
9. EL = PD × LGD × EAD
The Expected Loss (EL) formula combines the three components: PD, LGD, and EAD. It represents the estimated average loss on a loan or portfolio, considering the likelihood of default, the potential loss in case of default, and the exposure at the time of default.
