Default Risk: Comprehensive Definition, Types, and Measurement Methods

Default risk is crucial to understand for lenders and investors as it represents the uncertainty regarding a borrower's ability to meet debt obligations. This article explores the definition, types, and various measurement methods of default risk.

Default risk, also known as credit risk, entails the possibility that a borrower—whether a corporation or an individual—will be unable to make required payments on their debt obligations. This risk is of utmost importance to lenders and investors, as it affects interest rates, investment values, and financial stability.

Definition of Default Risk

Default risk is defined as the probability that a borrower will fail to meet their debt obligations, leading to a loss for the lender or investor. This risk is inherently tied to an entity’s creditworthiness and financial health.

Types of Default Risk

Corporate Default Risk

Corporate default risk refers to the likelihood that a business entity will be unable to pay back its debt. Factors influencing this type include the company’s financial performance, market conditions, and management quality.

Individual Default Risk

This type focuses on the probability that an individual borrower will fail to meet debt obligations. Important factors include the borrower’s credit history, income stability, and debt levels.

Sovereign Default Risk

Sovereign default risk is the risk that a government may fail to meet its debt obligations. Factors here include political stability, economic conditions, and foreign exchange reserves.

Measuring Default Risk

Credit Scoring Models

Credit scores, such as those provided by FICO or VantageScore, are numerical representations of an individual’s creditworthiness based on their credit history.

Financial Ratios

Key financial ratios, such as the Debt-to-Equity (D/E) ratio and Interest Coverage Ratio (ICR), are used to evaluate a company’s financial health and assess its likelihood of default.

Credit Spread

The credit spread, or yield spread, is the difference in yield between a corporate bond and a risk-free government bond. A wider spread indicates higher default risk.

Credit Default Swaps (CDS)

A CDS is a financial derivative allowing investors to swap credit risk. The cost of a CDS serves as a barometer for the default risk associated with a particular borrower.

Z-Score Model

Developed by Edward Altman, the Z-Score is a mathematical model used to predict bankruptcy based on various financial metrics including working capital, retained earnings, and EBIT.
