High-Yield Bond
A high-yield bond (also called a 'junk bond' or 'speculative-grade bond') is a corporate debt security rated below BBB- by S&P or below Baa3 by Moody's, indicating elevated credit risk of default relative to investment-grade bonds, and carrying a correspondingly higher yield to compensate investors for that additional risk. High-yield bonds bridge the gap between investment-grade corporate debt and equity in the capital structure.
Key takeaways
- High-yield bond issuers typically have leveraged balance sheets, cyclically sensitive revenues, limited asset coverage, or structural subordination within their capital structure.
- The yield spread over comparable U.S. Treasuries (the 'credit spread') is the primary valuation metric; spreads typically range from 200-600 basis points in normal markets and can spike to 1,000+ bps during recessions.
- High-yield bonds behave like a hybrid between investment-grade debt (rate sensitivity) and equity (earnings and cash flow sensitivity), with correlations to equities notably higher than for investment-grade bonds.
- The high-yield market was largely created by Michael Milken at Drexel Burnham Lambert in the 1980s, who demonstrated that a diversified portfolio of high-yield bonds could generate superior risk-adjusted returns.
- Key risk metrics for high-yield bond analysis include default probability, recovery rate, and loss given default (LGD), in addition to standard fixed-income duration and convexity measures.
Explanation
The high-yield bond market evolved from the 'fallen angel' bonds of the 1970s — investment-grade bonds that had been downgraded below BBB — into a vibrant new-issue market in the 1980s as Michael Milken at Drexel Burnham Lambert demonstrated that original-issue junk bonds could finance leveraged buyouts and corporate expansions at yields that more than compensated for default risk. The market has grown from a few billion dollars in the 1970s to over $1.5 trillion in face value in the U.S. alone by the early 2020s.
Credit ratings define the high-yield universe: bonds rated BB+/Ba1 to B-/B3 constitute the 'upper tier' of high yield, with better credit quality and lower spreads; bonds rated CCC/Caa and below are 'distressed' with high probability of near-term default or restructuring. Within each rating category, the spread (additional yield over U.S. Treasuries of similar maturity) reflects the market's assessment of default probability and expected recovery in default. Spread = Default Probability × Loss Given Default, a relationship formalized in structural credit models.
High-yield bond analysis combines credit analysis (assessing the issuer's ability to service and ultimately repay debt) with relative value analysis (comparing the bond's yield against comparable issuers and against its own historical spread). Credit analysis for high-yield issuers focuses on free cash flow generation (because the issuer has little equity cushion), covenant analysis (the protective provisions embedded in the bond indenture), capital structure position (senior secured versus senior unsecured versus subordinated), and industry dynamics that affect the company's earning power. Covenant analysis is particularly important in high-yield: covenants restrict additional debt issuance, asset sales, and distributions, protecting existing bondholders from having their priority claim diluted.
From an investment management perspective, high-yield bonds occupy a distinct role in asset allocation. Their return profile — equity-like in credit stress periods, bond-like in credit-benign periods — provides exposure to corporate credit risk premium that is partially distinct from both equity beta and interest rate risk. High-yield has historically generated annualized returns of 6-8%, significantly above investment-grade corporate bonds (4-5%) and comparable to equities (8-10%) but with lower volatility than equities over full cycles. High-yield mutual funds and ETFs (including the popular HYG and JNK ETFs) have democratized access to this asset class while introducing new liquidity considerations.
Formula
Spread ≈ Default Probability × Loss Given Default; Bond Yield = Risk-Free Rate + Credit Spread + Liquidity Premium
Example
Netflix Inc. issued $1.9 billion of high-yield bonds in 2019 in two tranches: $1.0 billion of 5.875% senior notes due 2029 (rated BB) and €900 million of 3.625% senior notes due 2027 (rated BB). At the time of issuance, the 5.875% coupon represented a spread of approximately 280 basis points over the 10-year U.S. Treasury yield, reflecting Netflix's then-high content investment spending and negative free cash flow despite strong subscriber growth. By 2022, as Netflix's free cash flow turned positive and the company was upgraded to investment grade by S&P, the secondary market yield on these bonds had tightened to approximately 5.2% — representing significant price appreciation for early buyers.
