A high-yield bond is a bond rated below the common investment-grade boundary, usually BB+ or lower at S&P Global Ratings and Fitch Ratings or Ba1 or lower at Moody’s. It is also called a speculative-grade or non-investment-grade bond. Its higher stated yield reflects greater perceived risk; it does not guarantee a higher realized return.
Key Takeaways
- High yield describes a credit-rating tier, not a bargain or a promised return.
- Higher coupon or yield can be offset by default, principal loss, weak recovery, price declines, calls, or trading costs.
- The bond’s place in the capital structure and its covenants can matter as much as the issuer’s broad rating.
- Original-issue high-yield bonds entered the market below investment grade; fallen angels crossed the boundary after a downgrade.
- A rating is an agency opinion at a point in time. It does not measure every risk or tell an investor whether the price is attractive.
Where High Yield Begins
The common market boundary depends on the rating scale:
| Agency scale | Lowest common investment-grade notch | Highest common high-yield notch |
|---|
| S&P / Fitch | BBB- | BB+ |
| Moody’s | Baa3 | Ba1 |
A bond can have different ratings from different agencies. An index, fund, or mandate may use the lowest rating, the middle rating, an average, or another documented hierarchy. A split-rated bond therefore may be high yield under one rule and investment grade under another.
How High-Yield Pricing Works
A high-yield bond’s yield can be viewed as a benchmark yield plus a credit spread:
1Bond yield = benchmark yield + spread
The spread is not pure expected profit. It can reflect expected default loss, uncertainty around recovery, liquidity, optionality, sector risk, and the return market participants demand for bearing those risks. It can widen sharply when the economy weakens, refinancing becomes difficult, or investors reduce credit exposure.
Coupon and yield are also different. Coupon is the contractual interest rate applied to face value. Yield incorporates the market price and expected cash flows under stated assumptions. A discounted bond may show a high yield because investors expect severe credit problems, not because its coupon changed.
Worked Example
Suppose a seven-year high-yield bond trades at a yield of 9.0%, while a similar-maturity government benchmark yields 4.0%.
19.0% - 4.0% = 5.0%, or 500 basis points
The 500-basis-point spread is compensation demanded by the market, not a forecast that the holder will earn five percentage points more. If the issuer misses payments and holders ultimately recover only part of principal, the loss can exceed years of coupon income. Even without default, a spread increase from 500 to 700 basis points would generally reduce the bond’s market price.
Assume the bond is callable at 102 in two years. If the issuer’s credit improves and refinancing rates fall, the issuer may redeem the bond. An analysis based only on yield to maturity could overstate the return available to the holder; yield to call and yield to worst are also relevant.
Original-Issue High Yield vs. Fallen Angel
| Feature | Original-issue high yield | Fallen angel |
|---|
| Status at issue | Below investment grade | Investment grade when issued or previously classified as such |
| Entry into high yield | Issued in the category | Downgraded across the boundary |
| Typical analytical focus | Leverage, business risk, covenants, refinancing | Deterioration, downgrade path, forced-flow risk, recovery plan |
| Market-flow effect | Part of the high-yield market from issue | May leave investment-grade mandates or indices under their rules |
The distinction does not establish which bond is safer or cheaper. A fallen angel can continue deteriorating, while an original-issue high-yield issuer can improve.
Main Risks
- Default risk: The issuer may miss interest or principal payments or complete a distressed exchange.
- Recovery risk: Collateral, guarantees, seniority, jurisdiction, and the debt stack affect what holders may recover after distress.
- Downgrade risk: A lower rating can widen spreads, reduce demand, and change index or mandate eligibility.
- Liquidity risk: Some bonds trade infrequently. Bid-ask spreads can widen during stress, and quoted prices may not be executable for the desired size.
- Refinancing risk: An issuer with a large maturity wall may be unable to refinance on acceptable terms.
- Call risk: The issuer may refinance when doing so is favorable to it, limiting the holder’s upside and creating reinvestment risk.
- Covenant risk: Weak covenants can allow more debt, asset transfers, restricted payments, or other actions that reduce creditor protection.
- Interest-rate and duration risk: High-yield bonds are still bonds. Changes in benchmark rates and duration affect price alongside credit conditions.
- Fund liquidity risk: A high-yield fund can face redemptions when underlying bonds are difficult to sell, creating transaction costs or realized losses.
How to Evaluate a High-Yield Bond
- Identify the exact obligation, including seniority, security, guarantees, maturity, coupon, call schedule, and currency.
- Read the offering document and bond indenture, not only the rating summary.
- Review leverage, fixed-charge or interest coverage, free cash flow, liquidity, covenant headroom, and the maturity schedule.
- Map the debt stack. A senior debt claim and subordinated debt from the same issuer may have different loss severity.
- Compare spread and yield with bonds of similar maturity, rating, sector, structure, and liquidity.
- Stress-test weaker earnings, higher rates, lower collateral values, delayed refinancing, and partial recovery.
- Check current ratings, outlooks, watch status, recent actions, and the market price rather than relying on an old label.
Common Mistakes
- Treating a high coupon as evidence that the bond is underpriced.
- Comparing yield with a government bond while ignoring default loss, liquidity, and embedded calls.
- Relying on an issuer rating when the specific issue has different priority or support.
- Assuming a secured label guarantees full recovery.
- Ignoring the price paid. The same cash flows can offer very different risk-adjusted value at different prices.
- Treating diversification as protection against market-wide spread widening or fund redemption pressure.

FAQs
Why do high-yield bonds offer higher yields?
The market generally requires more yield for greater default, recovery, liquidity, and uncertainty risks. The additional yield is compensation demanded for risk, not a guaranteed excess return.
Is every bond below BBB high yield?
On the S&P and Fitch long-term scales, BB+ and lower are commonly classified as high yield. On Moody’s scale, the comparable boundary is Ba1 and lower. Split ratings and mandate-specific rules can change how a particular portfolio classifies a bond.
Can a high-yield bond be secured?
Yes. A high-yield bond can be secured, unsecured, senior, or subordinated. Security may improve the holder’s claim on specified collateral, but it does not eliminate default or recovery risk.
