Investment-Grade Bond ETFs and Non-Investment-Grade Bond ETFs are two categories of bond exchange-traded funds (ETFs) that differ in the credit quality of the bonds they hold. Here’s an overview of each:
Investment-Grade Bond ETFs
- Definition: These ETFs invest primarily in bonds that are rated as “investment grade” by credit rating agencies like Moody’s, S&P, and Fitch. Investment-grade bonds have ratings of BBB- (S&P/Fitch) or Baa3 (Moody’s) and higher.
- Credit Quality: High credit quality. These bonds are issued by corporations, municipalities, or governments that are considered financially stable and less likely to default.
- Risk: Lower risk of default compared to non-investment-grade bonds. However, they typically offer lower yields.
- Return: Generally lower yields (interest rates) compared to non-investment-grade bonds because of the lower risk associated with them.
- Examples of ETFs:
-
- iShares iBoxx $ Investment Grade Corporate Bond ETF (LQD)
- Vanguard Intermediate-Term Corporate Bond ETF (VCIT)

Non-Investment-Grade Bond ETFs
- Definition: These ETFs invest primarily in bonds that are rated below “investment grade,” often referred to as “junk bonds” or “high-yield bonds.” These bonds have ratings below BBB- (S&P/Fitch) or Baa3 (Moody’s).
- Credit Quality: Lower credit quality. These bonds are issued by companies or entities that have a higher risk of default.
- Risk: Higher risk of default. Investors demand higher yields to compensate for the increased risk.
- Return: Higher yields compared to investment-grade bonds due to the increased risk. They offer the potential for higher returns but also come with a greater chance of losing principal if the issuer defaults.
- Examples of ETFs:
- SPDR Bloomberg High Yield Bond ETF (JNK)
- iShares iBoxx $ High Yield Corporate Bond ETF (HYG)
Summary
- Investment-Grade Bond ETFs are safer but offer lower yields.
- Non-Investment-Grade Bond ETFs are riskier but offer higher yields.
Investors typically choose between these options based on their risk tolerance, investment goals, and market outlook.
Credit Ratings and Their Importance
- Credit Ratings: Credit rating agencies (such as Moody’s, S&P, and Fitch) evaluate the creditworthiness of bond issuers. These ratings help investors assess the risk of default.
- Investment-Grade Bonds: Rated BBB-/Baa3 or higher, indicating a strong ability to meet financial commitments. Lower likelihood of default.
- Non-Investment-Grade Bonds (Junk Bonds): Rated below BBB-/Baa3, reflecting a higher risk of default. Issuers might have more unstable financial situations.
- Impact on Bond Prices and Yields:
- Investment-Grade Bonds: Due to their lower risk, these bonds offer lower yields. In times of economic uncertainty, their prices can rise as investors seek safety.
- Non-Investment-Grade Bonds: Higher yields compensate for the higher risk. However, in economic downturns, these bonds can suffer significant price drops as investors fear defaults.
2. Types of Bonds Within Each ETF
- Investment-Grade Bond ETFs:
- Corporate Bonds: Issued by financially stable companies. Offer a balance of yield and safety.
- Government Bonds: Issued by governments (like U.S. Treasuries). Generally very low risk.
- Municipal Bonds: Issued by local governments. Often offer tax benefits and are considered safe, especially those rated investment-grade.
- Non-Investment-Grade Bond ETFs:
- High-Yield Corporate Bonds: Issued by companies with lower credit ratings. These bonds offer higher returns due to the elevated risk.
- Emerging Market Bonds: Issued by governments or companies in emerging markets. These can offer high yields but carry political and economic risks.
3. Performance During Economic Cycles
- Investment-Grade Bond ETFs:
- During Economic Expansion: They might underperform relative to equities and high-yield bonds due to lower yields.
- During Economic Downturns: They tend to perform better, as investors flock to safer assets. Prices often increase due to higher demand for stability.
- Non-Investment-Grade Bond ETFs:
- During Economic Expansion: These ETFs often perform well as companies generally have better earnings, reducing the risk of default.
- During Economic Downturns: They are more vulnerable, with prices potentially dropping sharply due to increased default risk and reduced investor confidence.
4. Volatility and Liquidity
- Investment-Grade Bond ETFs:
- Volatility: Generally low volatility, making them suitable for conservative investors.
- Liquidity: High liquidity, especially for ETFs tracking large corporate or government bond indices.
- Non-Investment-Grade Bond ETFs:
- Volatility: Higher volatility due to the riskier nature of the underlying bonds.
- Liquidity: Can be less liquid than investment-grade bonds, particularly during market stress, leading to wider bid-ask spreads and potentially greater price fluctuations.
5. Suitability for Different Investors
- Investment-Grade Bond ETFs:
- Ideal For: Conservative investors, retirees, or those looking to preserve capital while earning a modest return. Suitable for portfolios focused on income with low risk tolerance.
- Portfolio Role: Often used as a core holding for diversification and stability. They provide steady income with relatively low risk.
- Non-Investment-Grade Bond ETFs:
- Ideal For: Investors with higher risk tolerance who are seeking higher yields and are willing to accept potential price volatility. Suitable for those looking to enhance income or take advantage of economic cycles.
- Portfolio Role: Typically used as a satellite holding to boost overall portfolio yield. They can add a layer of risk, so they’re often balanced with safer assets.
6. Interest Rate Sensitivity
- Investment-Grade Bond ETFs:
- Interest Rate Risk: Generally more sensitive to changes in interest rates. When rates rise, bond prices tend to fall, and vice versa. This is especially true for longer-duration bonds.
- Duration: Investment-grade bonds often have longer durations, meaning their prices are more affected by interest rate changes.
- Non-Investment-Grade Bond ETFs:
- Interest Rate Risk: Less sensitive to interest rates because the higher yield provides a cushion against rate increases. However, they can still be impacted by broader market trends.
- Duration: Typically shorter durations compared to investment-grade bonds, which makes them somewhat less sensitive to interest rate changes but more influenced by credit risk.
7. Tax Considerations
- Investment-Grade Bond ETFs:
- Interest income is typically taxed as ordinary income. However, municipal bond ETFs might offer tax-exempt income, making them attractive to investors in higher tax brackets.
- Non-Investment-Grade Bond ETFs:
- Interest income is usually taxed as ordinary income. Given the higher yields, this can result in a larger tax burden, which is important to consider for taxable accounts.
In summary, Investment-Grade Bond ETFs offer lower risk and more stability, making them suitable for conservative investors seeking steady income with minimal risk. They are ideal for those focused on preserving capital. In contrast, Non-Investment-Grade Bond ETFs provide higher yields but come with greater risk and volatility. These are better suited for investors with a higher risk tolerance who are seeking higher returns and are willing to accept the possibility of price fluctuations and potential losses.
The choice between the two depends on your investment objectives, risk tolerance, and market outlook. If you prioritize safety and stability, investment-grade bonds are likely the better choice. If you’re seeking higher income and can tolerate more risk, non-investment-grade bonds might be more appropriate. Balancing both types within a diversified portfolio can also help manage risk while enhancing returns.
