What Is Default Risk?
Default risk is the possibility that a borrower will be unable or unwilling to meet the terms of a debt. In practice, this means missing scheduled interest payments, failing to repay principal when it is due, or breaching conditions set out in a loan agreement. It applies to government bonds, corporate bonds, bank loans, mortgages, and other forms of credit. Investors who lend money accept this risk in exchange for interest income.
Default risk is one part of credit risk, which is the broader concern that a borrower's financial condition will weaken and reduce the value of its debt.
How Default Risk Is Assessed
Lenders and investors usually judge default risk by examining a borrower's ability to generate cash, its existing debt load, and its history of meeting obligations. Independent credit rating agencies publish letter-grade ratings that summarize this judgment, with the highest grades signaling the lowest perceived risk. Analysts also look at measures such as the debt-to-equity ratio and the interest coverage ratio, which compare a company's earnings or equity with its debt and interest costs.
Bonds with higher default risk typically offer a higher yield to compensate investors. The gap between a riskier bond's yield and that of a low-risk benchmark, such as a government bond, is called the credit spread.
Why It Matters to Investors
When a default occurs, bondholders may recover only part of their investment, and the recovery amount can vary widely depending on the borrower's remaining assets and the priority of the debt. Holders of senior secured debt generally have a stronger claim in bankruptcy than unsecured creditors or shareholders.
Default risk is one reason investors diversify across issuers and pay attention to credit quality. Holding a single high-yield bond exposes an investor to the full loss if that issuer defaults, while a broader mix spreads that exposure. Understanding default risk helps explain why one bond pays a higher yield than another and what that extra income may be compensating for.
