What Is High Yield Bonds?

High yield bonds, often referred to as "junk bonds," are a type of fixed income security issued by companies with lower credit ratings than investment-grade bonds. These bonds offer a higher interest rate, or yield, to compensate investors for the elevated default risk associated with the issuing entity's perceived weaker financial health or unproven operating history. High yield bonds are a significant component of the broader corporate bond market.⁷³, ⁷⁴, ⁷⁵, ⁷⁶

History and Origin

The modern high yield bond market largely took shape in the 1970s and flourished in the 1980s, driven by the efforts of financier Michael Milken at Drexel Burnham Lambert. Before this period, bonds rated below investment grade were primarily "fallen angels"—securities that had lost their higher ratings due to a decline in the issuer's financial stability. Milken, often dubbed the "junk bond king," recognized the potential in these overlooked securities. He pioneered the practice of actively underwriting and marketing new issues of high yield bonds for companies that previously had limited access to conventional capital markets. T⁷⁰, ⁷¹, ⁷²his innovation provided a new avenue for financing, significantly impacting mergers and acquisitions and leveraged buyouts throughout the 1980s. H⁶⁹owever, the rapid growth and aggressive use of these instruments also attracted regulatory scrutiny, leading to Milken's conviction for securities fraud and the eventual collapse of Drexel Burnham Lambert. D⁶⁷, ⁶⁸espite the controversies, his work fundamentally altered the landscape of corporate finance, establishing high yield bonds as an established capital market for raising funds.

⁶⁵, ⁶⁶## Key Takeaways

• High yield bonds compensate investors with higher interest rates due to their lower credit ratings and increased default risk.
• They are issued by companies with weaker financial profiles or less established histories.
• Despite higher risk, high yield bonds can offer diversification benefits within a portfolio and potentially higher returns compared to investment-grade debt.
• The market for high yield bonds gained prominence in the 1980s, largely due to Michael Milken's pioneering efforts.
• Investors often access high yield bonds through mutual funds or exchange-traded funds (ETFs) to mitigate individual bond risk.

Interpreting the High Yield Bond

High yield bonds are primarily interpreted through their yield, which reflects the compensation investors demand for taking on greater risk. A bond's yield to maturity (YTM) is a key metric, representing the total return an investor can expect if they hold the bond until it matures, taking into account its current market price, coupon payments, and principal repayment. For high yield bonds, this YTM is typically significantly higher than that of government bonds or investment-grade corporate bonds. For instance, the ICE BofA US High Yield Index Effective Yield, a benchmark for the U.S. high yield market, was approximately 6.8% as of July 2025, reflecting the average return expected from these riskier securities.

⁶², ⁶³, ⁶⁴Beyond the absolute yield, the spread between a high yield bond's yield and a comparable risk-free rate, such as a U.S. Treasury bond, known as the option-adjusted spread (OAS), provides insight into perceived credit risk. A widening OAS generally indicates increased investor apprehension about credit risk and potentially weakening economic conditions, as investors demand more compensation for holding riskier assets. C⁵⁹, ⁶⁰, ⁶¹onversely, a narrowing spread suggests greater investor confidence.

⁵⁸## Hypothetical Example

Consider "Horizon Innovations," a relatively new technology company seeking capital to expand its operations. Due to its limited operating history and high leverage, major credit rating agencies assign Horizon Innovations a "BB" credit rating, placing its debt in the high yield category.

To raise funds, Horizon Innovations issues a $1,000 bond with a 10% annual coupon and a maturity of five years. An investor, Sarah, purchases this bond.

• Initial Investment: $1,000 (the bond's principal)
• Annual Coupon Payment: $1,000 * 10% = $100

Each year, Sarah receives $100 in interest. At the end of five years, Horizon Innovations repays Sarah her initial $1,000 principal. The higher 10% coupon rate reflects the market's assessment of Horizon Innovations' increased default risk compared to a more established company that might issue a bond with a 4% coupon. If Horizon Innovations improves its financial standing and its credit rating is upgraded, the value of Sarah's bond could appreciate, offering a capital gain in addition to the regular income stream. However, if the company's performance deteriorates, the bond's price could fall, and there's a risk of delayed or missed payments. This scenario highlights how the higher yield is a direct reflection of the compensation for assuming greater risk in lending to companies like Horizon Innovations.

Practical Applications

High yield bonds play a crucial role in the financial markets, serving various practical applications for both issuers and investors. For companies, especially smaller, emerging, or highly leveraged firms, high yield bonds offer a vital source of capital that might otherwise be unavailable from traditional lenders or public equity markets. T⁵⁶, ⁵⁷his enables them to fund operations, finance growth initiatives, and restructure existing debt.

⁵⁵For investors, high yield bonds can be an attractive component of a diversified portfolio, offering the potential for higher income generation compared to lower-risk fixed income assets. H⁵³, ⁵⁴istorically, high yield securities have provided competitive returns, sometimes even comparable to equity markets, but with generally lower volatility. T⁵⁰, ⁵¹, ⁵²hey can also provide diversification benefits as their performance may not always correlate directly with other bond market segments or equities. F⁴⁷, ⁴⁸, ⁴⁹or example, while the ICE BofA US High Yield Index Effective Yield has fluctuated, it generally offers a spread over U.S. Treasury securities, compensating investors for assuming additional credit risk. T⁴⁵, ⁴⁶he average annual default rate for the U.S. high yield market over the 2000-2023 period was approximately 2.5%, indicating that while defaults occur, the asset class often provides sufficient yield to compensate for these occurrences over the long term.

⁴³, ⁴⁴## Limitations and Criticisms

Despite their potential for higher returns, high yield bonds come with significant limitations and criticisms, primarily stemming from their elevated risk profile. The most prominent concern is the increased default risk, meaning the possibility that the issuer will fail to make timely interest or principal payments. H³⁹, ⁴⁰, ⁴¹, ⁴²istorically, the aggregate default rate for high yield bonds has fluctuated, soaring to 11% in 1991 during a mild recession, compared to an average of just under 4.5% since 1981. M³⁷, ³⁸ore recently, the average annual default rate for the U.S. high yield market has been around 2.5% between 2000 and 2023. W³⁵, ³⁶hile this is higher than for investment-grade bonds, some analyses suggest that actual index default rates can be lower than agency estimates.

³³, ³⁴Another significant risk is interest rate risk, although high yield bonds can be less sensitive to interest rate fluctuations than investment-grade bonds due to their shorter durations and higher coupon payments. H³¹, ³²owever, like all bonds, their prices move inversely to interest rates. [²⁹, ³⁰Liquidity risk](https://diversification.com/term/liquidity_risk) is also a concern, as high yield bonds may be less actively traded than investment-grade securities, making them harder to buy or sell quickly without impacting their price. F²⁷, ²⁸urthermore, periods of economic weakness can disproportionately affect the high yield market, leading to wider credit spreads and potential price declines as investors seek "flight to quality" assets. I²⁴, ²⁵, ²⁶nvestors must carefully assess these risks, as "covenant-lite" bonds, which offer fewer protections for bondholders, have become more prevalent when demand for high yield bonds is strong.

²², ²³## High Yield Bonds vs. Investment-Grade Bonds

The primary distinction between high yield bonds and investment-grade bonds lies in their creditworthiness and the compensation offered to investors for assuming risk.

While investment-grade bonds are favored by investors prioritizing capital preservation and predictable income, high yield bonds attract those willing to accept greater risk in pursuit of potentially higher returns. T⁷, ⁸he "junk bond" moniker, while historically carrying a negative connotation, simply denotes their lower credit quality, not necessarily a guaranteed loss.

FAQs

What does "high yield" mean for bonds?

"High yield" indicates that a bond offers a higher interest rate compared to investment-grade bonds. This higher rate compensates investors for the increased risk of the issuer defaulting on its payments, as these bonds are issued by companies with lower credit ratings.

⁵, ⁶### Are high yield bonds suitable for all investors?
No, high yield bonds are generally not suitable for all investors. They carry a higher level of risk, particularly default risk and price volatility, making them more appropriate for investors with a higher risk tolerance and a well-diversified portfolio who can withstand potential losses.

⁴### How can investors gain exposure to high yield bonds?
Investors can gain exposure to high yield bonds by purchasing individual bonds directly, although this carries significant individual default risk. A more common approach, especially for retail investors, is to invest through diversified high yield bond mutual funds or exchange-traded funds (ETFs), which hold portfolios of many different high yield bonds, thereby spreading out the risk.

³### Do high yield bonds always outperform investment-grade bonds?
No, high yield bonds do not always outperform investment-grade bonds. While they offer higher potential returns and yields, their performance is more sensitive to economic downturns and changes in credit conditions. During periods of economic stress, their prices can fall significantly due to increased default concerns, leading to underperformance compared to safer investment-grade debt.¹, ²
