Key Points

Fixed-income exchange-traded funds provide diversified bond exposure, often at a low cost.
Passive fixed-income ETFs lower expenses because they rely on an index to define their holdings.
Investors should assess strategy, expenses, and tax implications before investing.

Fixed-income ETFs may play an important role in your investing strategy, especially if you are an individual investor. Let's learn more about these accessible assets that can deliver income and stability to your portfolio.

Understanding fixed income ETFs

Fixed-income ETFs are exchange-traded funds that invest in debt. Debt securities can be bonds or preferred securities. Both represent debts made to the security issuer from the shareholders. In this case, the ETF is the shareholder. The ETF, in turn, sells shares of its portfolio to other investors.

Debt issuers make interest payments and principal repayments to the ETF. The ETF divvies up these cash inflows to pay its expenses, reinvest, and provide income to its shareholders. ETF shareholders benefit by receiving income from the underlying securities, without having to manage the portfolio themselves.

Fixed-income ETFs are particularly useful for non-professional investors. Non-professionals, known as retail investors, have limited options for buying bonds directly.

Types of fixed-income ETFs

Fixed-income ETFs are categorized by their investing strategy and their holdings. At the highest level, their strategy can be active or passive.

Active fixed-income ETFs have a team of managers researching and selecting debt securities for maximum returns. These funds have higher expense ratios and the potential to outperform the broader market.
Passive fixed-income ETFs use an index to define their holdings. These funds have low expense ratios and should perform in line with their underlying index.

Active and passive ETFs can invest broadly in debt across issuer types, maturities, and geographies. More commonly, though, they have a defined focus on one asset type, such as:

Government bonds are issued by federal governments. The U.S. government, for example, issues Treasury securities in a range of maturities.
Municipal bonds are issued by local and state governments. These are often exempt from state and federal taxes.
Investment-grade corporate bonds are issued by corporations. These securities have good credit, as measured by bond rating agencies such as Moody's and Fitch.
Preferred securities are fixed-income assets that have an ownership component. Credit rating agencies also rate preferred securities so investors can more easily evaluate their risk.
High-yield bonds, also known as junk bonds, have lower credit ratings and higher default risk. They pay higher yields to compensate investors for the added risk.
U.S. bonds include debt securities denominated in U.S. dollars and issued by U.S. entities. These can be government, municipal, or corporate bonds.
International bonds are issued in foreign currency by a government or corporate issuer based outside the U.S.

Fixed-income ETF examples

Major and minor fund families offer many varieties of fixed-income ETFs. Vanguard, for example, has more than two dozen fixed-income funds with expense ratios of 0.2% or less. The largest in terms of assets under management include:

Vanguard Intermediate-Term Tax-Exempt Bond ETF (VTEI -0.14%) invests in tax-exempt, investment-grade, U.S. municipal bonds with maturities up to 20 years.
Vanguard Core-Plus Bond ETF (VPLS +0.03%) provides broad exposure to U.S. investment-grade bonds. The portfolio includes government, corporate, and mortgage-backed securities.
Vanguard Short-Term Tax-Exempt Bond ETF (VTES +0.00%) invests in tax-exempt, investment-grade U.S. municipal bonds with maturities of one month to seven years.
Vanguard ESG U.S. Corporate Bond ETF (VCEB +0.13%) holds investment-grade taxable bonds issued by U.S. corporations that pass environmental, social, and governance (ESG) screening criteria. ESG is a framework for measuring and reporting on sustainability risks and initiatives.

These funds have defined investment strategies that appeal to specific investors. You can also opt for a broader fixed income fund, such as Vanguard's Total World Bond ETF (BNDW -0.01%).
