What Are High-Yield Bond ETFs?
High-yield bond ETFs hold corporate bonds rated below investment grade — BB+ or lower by S&P, Ba1 or lower by Moody's. These bonds are issued by companies with weaker credit profiles, higher debt loads, or less established business models. To compensate investors for the elevated default risk, these bonds pay significantly higher interest rates than investment-grade alternatives.
The "high-yield" label is the polite term; the historical name is "junk bonds." While the label sounds alarming, high-yield bonds serve an important function in both the economy and in investment portfolios. They allow growing companies to access capital markets and provide investors with income that far exceeds what treasury or investment-grade bonds offer.
High-yield bond ETFs package hundreds of these bonds into diversified funds, spreading the risk of any single company defaulting across a broad portfolio. This diversification is crucial because individual high-yield bonds can and do default. The ETF structure transforms a risky individual investment into a more manageable portfolio allocation.
Top High-Yield Bond ETFs Compared
HYG — iShares iBoxx $ High Yield Corporate Bond ETF
HYG is the largest and most liquid high-yield bond ETF, holding approximately 1,200 bonds at 0.49%. It tracks the iBoxx USD Liquid High Yield Index and pays monthly distributions. HYG's massive liquidity makes it the preferred choice for institutional investors and traders. Its tight bid-ask spreads minimize trading costs.
JNK — SPDR Bloomberg High Yield Bond ETF
JNK holds roughly 1,000 high-yield bonds at 0.40%, tracking the Bloomberg High Yield Very Liquid Index. JNK tends to have a slightly higher yield than HYG and a marginally lower expense ratio. Both funds provide broad high-yield exposure, and performance differences are usually small.
USHY — iShares Broad USD High Yield Corporate Bond ETF
USHY offers the broadest high-yield exposure with about 2,000 holdings at just 0.15% — significantly cheaper than HYG or JNK. It tracks the ICE BofA US High Yield Constrained Index. For buy-and-hold investors who prioritize low cost and broad diversification, USHY is an excellent choice.
SHYG — iShares 0-5 Year High Yield Corporate Bond ETF
SHYG focuses on short-duration high-yield bonds maturing in five years or less. This shorter duration reduces interest rate sensitivity while maintaining the credit spread income. SHYG offers a more conservative approach to high-yield investing with less price volatility.
Understanding Credit Risk
Credit risk — the possibility that a bond issuer fails to make interest or principal payments — is the defining feature of high-yield bonds. Default rates fluctuate with economic conditions. In normal economic environments, roughly 2-3% of high-yield bonds default annually. During recessions, this rate can spike to 10% or higher.
The 2008 financial crisis saw high-yield default rates exceed 12%, and bond prices dropped over 25%. The March 2020 pandemic shock caused high-yield spreads to blow out, with prices dropping 20% in weeks before recovering. These episodes demonstrate that high-yield bonds carry equity-like downside risk during crises.
However, the historical record shows that high-yield bonds have been adequately compensated for their default risk over long periods. The extra yield has more than covered default losses, delivering total returns between stocks and investment-grade bonds. This favorable risk-reward profile is why many financial advisors include high-yield in diversified portfolios.
High-Yield Bonds vs. Stocks vs. Investment-Grade Bonds
High-yield bonds occupy a middle ground between stocks and investment-grade bonds in terms of both risk and return. They provide more income than investment-grade bond ETFs but less capital appreciation potential than stocks. They are less volatile than equities but more volatile than treasury ETFs.
The critical nuance: high-yield bonds correlate more with stocks than with investment-grade bonds. During stock market selloffs, high-yield bonds typically decline alongside equities because credit risk increases when the economy weakens. This means high-yield bond ETFs provide less diversification benefit than treasury or investment-grade bond ETFs.
This correlation characteristic means that replacing your entire bond allocation with high-yield would increase portfolio risk during downturns. A better approach uses high-yield as a supplement to, rather than a replacement for, investment-grade bonds. A core bond holding like BND paired with a modest HYG or JNK allocation captures extra income without abandoning the diversification benefit of quality bonds.
When High-Yield Bond ETFs Shine
High-yield bonds perform best in specific economic environments. Early in an economic recovery, high-yield bonds often deliver equity-like returns as credit conditions improve and default fears recede. They also perform well in stable growth environments where companies can comfortably service their debt.
Rising interest rates affect high-yield bonds less than investment-grade bonds because their higher coupon provides more cushion, and improving economic conditions (which often drive rate hikes) reduce default risk. During the 2022 rate hiking cycle, high-yield bonds outperformed long-duration treasuries for this reason.
The worst environment for high-yield is an economic recession or credit crisis when defaults spike and investors flee risky assets. In these conditions, high-yield bonds can lose 20-30%, approaching equity-like drawdowns. This is why position sizing matters — a 5-15% allocation provides income enhancement without dominating portfolio risk.
High-Yield Bond ETFs for Income Investors
For income-focused investors, high-yield bond ETFs offer yields significantly above other fixed income options. HYG and JNK typically yield 5-7%, compared to 3-5% for investment-grade corporate bonds and 3-4% for treasuries. This income premium can meaningfully boost portfolio cash flow.
Monthly distributions from high-yield ETFs provide regular income, making them practical for investors drawing down portfolios in retirement. Combined with dividend equity ETFs and treasury ETFs, high-yield bonds complete a diversified income strategy.
Be aware that high-yield bond interest is taxed as ordinary income, not at the favorable qualified dividend rate. This makes high-yield bond ETFs particularly well-suited for tax-advantaged accounts like IRAs. Compare high-yield bond ETFs on our ETF screener to evaluate current yields and credit quality.
