What Is a High-Yield Bond?
A bond paying a noticeably higher coupon than its peers usually isn’t a mispriced bargain — it’s compensation for something. In the case of high-yield bonds, that something is a meaningfully higher chance the issuer runs into trouble.
The short answer
A high-yield bond, sometimes called a junk bond, is a corporate bond issued by a company with a credit rating below investment grade. Because credit rating agencies view these issuers as carrying a higher risk of default than investment-grade companies, high-yield bonds pay a higher coupon to compensate investors for taking on that added risk. They sit at the riskier end of the corporate bond spectrum.
How the rating threshold works, conceptually
Credit rating agencies assign letter-grade ratings to corporate bond issuers based on an assessment of their ability to meet debt obligations. Above a certain threshold, bonds are considered “investment grade,” reflecting a lower assessed risk of default. Below that threshold, bonds are classified as high-yield or below investment grade, reflecting a higher assessed risk. These thresholds and the specific rating categories are set by the rating agencies and can be revised over time, so it’s the relative positioning — investment grade versus below investment grade — that matters more than memorizing any particular rating label.
A rating is an assessment, not a certainty, and rating agencies can and do revise their views as a company’s financial condition changes, sometimes moving a bond between categories during its life.
Why high-yield bonds behave more like stocks in downturns
- Default risk rises during economic stress. When the broader economy weakens, lower-rated companies are more likely to struggle with debt payments than higher-rated ones, which means high-yield bond prices often fall alongside stock prices during downturns, unlike higher-quality bonds that sometimes hold up or even gain value in the same environment.
- Correlation with equity markets tends to increase. Because both stock prices and high-yield bond prices are sensitive to a company’s business prospects and overall economic conditions, high-yield bonds tend to move more in tandem with stocks than investment-grade bonds do, reducing some of the diversification benefit that bonds typically provide within a portfolio.
- Spread widening reflects rising fear, not just rates. The extra yield high-yield bonds pay over safer bonds — the “spread” — tends to widen when investors grow more worried about defaults, which can happen independently of, or in addition to, moves in overall interest rates.
What to weigh before considering high-yield exposure
Higher yield is compensation for a real, measurable increase in the chance of missed payments or default, not a free lunch. Evaluating a high-yield bond means weighing the issuer’s specific financial situation, not just the attractiveness of the coupon rate, and understanding that these bonds can lose significant value during exactly the kind of economic stress when an investor might least want that to happen. Many investors access high-yield exposure through a diversified fund rather than individual bonds, since spreading risk across many issuers can reduce the impact of any single company’s default.
How it compares with other bond types
Unlike a floating-rate bond, where the primary risk driver is a resetting reference rate, a high-yield bond’s primary risk driver is the issuing company’s own creditworthiness. And unlike government-backed debt such as an agency bond, high-yield bonds carry no government support at all — their repayment depends entirely on the issuing company’s own financial performance.
The bottom line
A high-yield bond’s elevated coupon exists to compensate for elevated default risk, and that risk tends to show up at the worst possible times — during broader economic weakness, when high-yield bonds often behave more like stocks than like traditional safe-haven bonds. Weighing the coupon against that reality, rather than the coupon alone, is essential before adding high-yield exposure to a portfolio.
