How To Invest In Bonds: Pros, Cons, and Risks

Stocks and bonds are often discussed together, and for good reason. Most investors use both in their asset allocation. Bonds are the more conservative counterpart to stocks, added to a portfolio to provide principal stability and a steady stream of interest income. Since bonds are part of any well-constructed portfolio, understanding how they work and how to invest in them is essential for any investor.

This guide covers what bonds are, the different types available, the risks involved, and how to determine the right bond allocation for your portfolio.

What Are Bonds?

Bonds are debt securities issued by corporations and governments. They typically come in denominations of $100 to $1,000, the amount the issuer guarantees to pay upon maturity. A fixed interest rate is paid on the security between the purchase date and the maturity date.

Governments issue bonds to finance capital improvements, such as roads, bridges, power plants, or general budget operations. Corporations issue bonds to raise capital for short-term needs, such as increasing cash or purchasing inventory, or for longer-term capital projects, such as acquiring equipment, buildings, or other companies.

The term bonds technically refers to long-term debt securities with maturities greater than 10 years. However, in common usage, it has become a catchall phrase describing all types of fixed-income investments, including Treasury bills and even certificates of deposit. Loosely speaking, bonds describe the fixed-income portion of your portfolio.

The Benefits of Investing in Bonds

Portfolio Stability

The basic purpose of bonds is to add stability to a portfolio by reducing overall risk. Since stock prices can rise and fall significantly, the more stable value of bonds acts as a counterweight. When stock prices fall, bond prices tend to remain relatively constant, reducing the overall volatility of a blended portfolio.

For example, in a portfolio comprising 50% stocks and 50% bonds, a 20% decline in stocks would reduce the overall portfolio by just 10%, since only half the portfolio is in equities.

Steady Interest Income

Bonds pay a fixed rate of interest, unlike dividends, which can be reduced or eliminated at any time. Since a bond is a legal, contractual obligation of the issuer, they must pay interest according to the terms of the security. Even if an issuer loses money and cannot pay dividends, it is still required to pay interest on its bonds, unless it defaults entirely.

Potential for Capital Appreciation

Investors do not typically buy bonds primarily for capital appreciation, but bonds do have this potential. If interest rates fall after you purchase a bond, the market value of the bond tends to rise. For example, a 20-year $1,000 corporate bond purchased at a 5% interest rate pays $50 per year in interest. If prevailing rates fall to 4%, the value of the bond may rise to $1,250, because the $50 annual interest would represent a 4% return at that higher value. This inverse relationship between bond prices and interest rates is one of the most important concepts in fixed-income investing.

The Risks of Investing in Bonds

Default Risk

The most obvious risk is the potential for issuer default. If a corporation that issues bonds goes out of business, those bonds may become worthless. While it is theoretically possible for states and local governments to default on municipal bonds, it is historically rare. By contrast, US Treasury securities are considered impervious to default; the US government can tax, borrow, or create money to pay the interest and principal on its securities.

Interest Rate Risk

Interest rate risk is the most significant risk inherent to all bonds, including US Treasuries. As described above, if interest rates rise after you purchase a bond, the market value of that bond falls. For example, a $1,000 20-year bond issued at a 4% interest rate pays $40 per year. If prevailing rates rise to 5%, the bond’s market value may fall to $800, because $40 would represent a 5% return at that lower price.

It is important to understand that this is a market fluctuation; if you hold the bond until maturity, you will receive the full face value regardless of what happens to interest rates in the interim. The risk primarily affects investors who need to sell bonds before maturity.

The Different Types of Bonds

Corporate Bonds

Corporate bonds are debt securities issued by public corporations and traded on national exchanges. They can be purchased through investment brokerage firms. A typical bond term is 20 years, and they are usually purchased in minimum denominations of $1,000, though brokers may require a minimum purchase of 10 bonds, or $10,000.

The risk level of corporate bonds varies significantly. You can evaluate this risk through major bond rating agencies, including Moody’s, Fitch, and Standard & Poor’s. There are two basic classes:

• Investment-grade bonds — rated AAA, AA, A, or BBB. AAA is the highest-rated bond, while BBB is the lowest in the investment-grade class.

• High-yield bonds — rated BB and below. These bonds pay higher interest than investment-grade bonds because they carry a greater risk of default. Despite the more appealing name, these are still higher-risk securities that deserve careful scrutiny before investing.

Municipal Bonds

Municipal bonds are issued by states, counties, municipalities, and agencies. Their major advantage is that interest is exempt from federal income tax and, if you live in the state where the bonds are issued, from state income tax, making it double tax-free. Because of this tax-exempt status, municipal bonds are best held in taxable investment accounts rather than tax-deferred accounts like IRAs, where the tax exemption provides no additional benefit.

Like corporate bonds, municipal bonds can be purchased through investment brokerage firms and should be evaluated using the same three rating agencies listed above.

US Treasury Securities

US Treasury securities are the safest bonds available, backed by the full faith and credit of the US government. They can be purchased through TreasuryDirect.gov or through an investment broker. Treasury securities come in several types:

• Treasury bills — maturities of a few days to 52 weeks, available in denominations of $100, sold at a discount. For example, you might pay $98 for a bill that repays $100 at maturity, and the $2 difference is the interest earned.

• Treasury notes — maturities of 2 to 10 years, purchased in denominations of $100, paying interest every six months.

• Treasury bonds — 30-year terms, available in denominations of $100, paying interest every six months and face value at maturity. The 30-year Treasury bond is currently yielding approximately 5.2%, its highest level since 2007.

• Treasury Inflation-Protected Securities (TIPS) — issued with terms of 5, 10, and 30 years. The principal value adjusts based on the Consumer Price Index, rising with inflation and falling with deflation. If held to maturity, you receive the greater of the original face amount or the inflation-adjusted value.

• Savings bonds — including EE bonds purchasable for as little as $25, and I bonds, which provide additional inflation-adjusted principal similar to TIPS.

Interest from all US Treasury securities is exempt from state income tax, a meaningful advantage for investors in high-tax states.

Using TIPS and I Bonds to Preserve Capital

Treasury yields are currently at their highest levels in nearly two decades, with the 30-year Treasury bond recently hitting 5.2% and the 10-year note yielding approximately 4.67%. This makes Treasury bonds significantly more competitive with other investments than they were during the near-zero rate environment of 2020-2022.

For investors specifically concerned about inflation eroding purchasing power, TIPS and I Bonds offer built-in protection. Both are tied to the Consumer Price Index, providing returns that keep pace with inflation rather than erode it.

For I Bonds, there is a variable rate component in addition to the fixed rate that adjusts every six months based on CPI. The current composite rate for I Bonds issued May through October 2026 is 4.26%. For TIPS, the adjustment is made to the principal every six months, though you will not receive the increased principal until the bond matures.

Taxes on TIPS and I Bonds

Both TIPS and I Bonds are subject to federal income tax, though they are exempt from state and local taxes. With I Bonds, you can defer reporting the interest until the bonds are redeemed. TIPS are different; you must pay taxes on earnings as you receive them, including the inflation adjustment to principal, even though you do not receive that cash until maturity. To offset this, consider holding TIPS in a tax-advantaged retirement account where you will not owe taxes until withdrawal.

Should You Invest in a Bond Fund?

A bond fund is a professionally managed portfolio of bonds and other debt instruments. It allows you to spread risk across a broad range of individual securities, making it more accessible than buying individual bonds, particularly for smaller portfolios.

There are three main types of bond funds:

Open-End Bond Mutual Funds

You can buy or sell shares at any time, but the price is calculated once per day based on the net asset value of the underlying bonds.

Closed-End Bond Mutual Funds

A limited number of shares are listed and sold. Price fluctuates based on the underlying securities but also reflects supply and demand dynamics.

Exchange-Traded Bond Funds (ETFs)

Bond ETFs trade on an exchange just like stocks, meaning the price changes throughout the day as shares are bought and sold. Bond ETFs are generally the most accessible and cost-effective option for most individual investors, offering diversification across many bond issues with low expense ratios and commission-free trading at most major brokerages.

The Hidden Risks of Bond Funds Most Investors Overlook

Bond funds are not as risk-free as they might appear. Two key risks apply:

Default risk — bond funds that hold corporate or municipal bonds carry the risk that individual issuers within the fund may default. This risk can be minimized by choosing funds that invest exclusively in US government securities.

Interest rate risk — all bond funds are subject to interest rate risk. When rates rise, bond prices fall, and this is especially pronounced for funds holding longer-term bonds. A 30-year bond with 25 years remaining is highly sensitive to interest rate changes, while a 10-year bond with three years remaining is minimally affected since the ultimate payoff is so close.

If you want bond funds to offset equity risk in your portfolio, consider funds primarily invested in US government securities with maturities of less than 10 years. This eliminates default risk and minimizes interest rate risk.

Also, pay careful attention to fund portfolio composition. Some funds described as government bond funds may hold foreign government bonds, introducing currency risk. Always review the fund’s prospectus before investing to confirm the holdings match your investment goals.

Why Bonds Are More Attractive in 2026 Than They Have Been in Years

With Treasury yields at multi-decade highs, bonds are more attractive than they have been in years. Here are four scenarios where bonds make sense in 2026:

• 1. Locking in current yields before rates potentially fall. With the 30-year Treasury yielding around 5%, investors who lock in these rates now benefit significantly if rates decline over the coming years, capturing both the attractive yield and potential capital appreciation.

• 2. Interest rates could fall from current highs, raising bond prices. With rates at their highest levels since 2007, there is a meaningful case that they could decline from here. If they do, bond prices would rise, giving current bondholders both income and capital gains.

• 3. Bonds as a safe haven during stock market volatility. With equity valuations elevated and economic uncertainty present, bonds — particularly US Treasuries — now offer genuinely competitive yields with significantly lower volatility than stocks.

• 4. International instability driving demand for US Treasuries. Periods of global geopolitical uncertainty historically drive demand for US Treasury securities as a safe haven, which can push yields down and bond prices up, benefiting existing bondholders.

Are Stocks and Bonds as Mutually Exclusive as You Think?

One important caveat to the traditional stocks-and-bonds diversification argument: historically, stocks and bonds have both risen and fallen in response to changes in interest rates. When rates fall, both tend to rise. When rates rise, as they have recently, both can fall together.

This correlation means bonds may not provide the pure diversification benefit many investors expect. For this reason, shorter-term bonds and TIPS are generally more effective as portfolio stabilizers than long-term bonds, which tend to correlate more closely with equity market movements.

How and Where to Buy Bonds

• Corporate and municipal bonds — available through most investment brokers, including Vanguard, Fidelity, and Charles Schwab

• US Treasury securities — available directly through TreasuryDirect.gov with no broker fees, or through most major brokerages

• Bond funds and ETFs — available commission-free through most major brokerages, and are generally the most practical option for most individual investors

For most individual investors with smaller portfolios, bond ETFs are the most cost-effective and accessible option. For larger portfolios, individual bonds offer more control over specific maturities and credit quality.

How Much Should You Invest in Bonds?

The right bond allocation depends primarily on your risk tolerance and time horizon. A commonly cited rule of thumb is 120 minus your age for the percentage of your portfolio allocated to stocks, with the remainder in bonds.

For example:

• At age 30: 90% stocks, 10% bonds (120 – 30 = 90)

• At age 50: 70% stocks, 30% bonds (120 – 50 = 70)

• At age 65: 55% stocks, 45% bonds (120 – 65 = 55)

This is a starting point, not a rigid formula. Adjust your bond allocation based on your personal risk tolerance, how soon you will need the funds, and your other sources of retirement income.

A Note for Military Members

For military members with a pension and TSP already providing significant retirement income, the bond allocation in a taxable portfolio may be lower than the rule of thumb suggests, since the pension effectively functions as a large fixed-income asset in the overall financial picture. The TSP’s G Fund and F Fund already provide significant exposure to government and bond securities at extremely low cost; military investors should account for this when determining how much additional bond exposure to add through individual bonds or bond funds.

Building a Bond Strategy That Works for You

Bonds are an essential component of a well-diversified investment portfolio, providing stability, income, and a counterweight to equity volatility. With Treasury yields currently at their highest levels in nearly two decades, bonds are more attractive than they have been in years, offering competitive yields with the safety and liquidity that make US Treasury securities one of the most valuable asset classes available to any investor.

The key is matching your bond investments to your specific goals, time horizon, and risk tolerance, and understanding the trade-offs between different bond types, maturities, and funds before committing your money.
