The disadvantages of investing in bonds come down to a core trade-off and a stack of specific risks layered on top of it. In exchange for steadier income, you accept lower long-term growth, and you take on interest rate risk, inflation risk, default risk, call risk, less favorable tax treatment, and in many cases poor liquidity. The “safe” label bonds often wear oversells what you actually get.
Lower Long-Term Returns Than Stocks
Since 1926, bonds have returned roughly 4% to 6% a year, compared with 8% to 10% for stocks. Over a decade or two, that gap compounds into a very different ending balance. For a younger investor who doesn’t need the income yet, a bond-heavy allocation is a drag on growth. Retirees have good reason to hold bonds for stability, but even they need to think about how much growth they’re giving up over a 25- or 30-year retirement, because a portfolio tilted too far toward bonds may not keep pace with inflation.
Prices Fall When Interest Rates Rise
Bond prices and interest rates move in opposite directions. When the Federal Reserve raises the federal funds rate, newly issued bonds carry higher coupons, and older bonds with lower coupons become less attractive on the secondary market. To sell an existing bond, you have to drop the price until its effective yield matches what buyers can get on new issues. That price drop is a real loss if you need to sell before maturity.1Federal Reserve Board. Monetary Policy: What Are Its Goals? How Does It Work?
How big that drop gets depends on duration. A bond with a modified duration of 7 loses about 7% of its market value if rates rise one percentage point. Longer-term bonds carry higher durations and get hit harder. A 30-year Treasury can swing dramatically on a single rate announcement, while a 2-year note barely moves. Investors who think of bonds as uniformly safe sometimes learn this during a rate-hiking cycle, when their conservative holdings drop 10% or more in a year.
Inflation Erodes What Your Coupons Buy
A bond paying 4% sounds fine until inflation runs at 5%. The coupon payments are fixed, so when prices in the broader economy rise, each dollar of bond income buys less. Over a 20-year holding period, moderate 3% inflation cuts the real value of your principal nearly in half by the time it comes back at maturity.
This hits retirees hardest. Groceries, healthcare, and housing don’t stay flat for two decades, but bond coupons do. Treasury Inflation-Protected Securities adjust their principal with the Consumer Price Index, which helps, but TIPS pay lower starting yields than comparable nominal bonds, and the inflation adjustments are taxed every year even though you don’t receive the added principal until maturity. A partial solution, not a complete one.
The Issuer May Not Pay You Back
Every bond carries the risk that the issuer defaults. Credit rating agencies assess this risk and assign ratings, and a downgrade pushes a bond’s market price down right away, often well before any missed payment.
If an issuer files for bankruptcy, federal law sets a strict payment order. Secured creditors with claims backed by specific collateral get paid first, up to the value of that collateral.2Office of the Law Revision Counsel. 11 U.S. Code 506 – Determination of Secured Status Administrative costs and other priority claims come next.3Office of the Law Revision Counsel. 11 U.S.C. 507 – Priorities Unsecured bondholders sit further down and often recover only a fraction of what they’re owed. Investment-grade corporate bonds default rarely; high-yield (junk) bonds are another story, and the higher coupon is compensation for a real chance the issuer goes under.
Corporate Actions Can Hurt Bondholders Overnight
Even without a default, a corporate restructuring can damage your position. When a company becomes the target of a leveraged buyout, the acquirer loads the balance sheet with new debt, pushing existing bonds into riskier territory and dropping their prices. Studies of 1980s buyouts found bondholders in acquired companies posted average abnormal losses, while stockholders in the same deals captured large gains.
The variable that decides the outcome is covenant protection. Bonds with strong covenants, including change-of-control provisions that let holders demand repayment if the company is acquired, actually gained value in those deals. Bonds with weak or no covenants absorbed the losses. This risk doesn’t show up in a credit rating or a yield number at the time of purchase. Reading the indenture for covenant protections is worth the effort, even though almost nobody does it.
Callable Bonds Can Be Taken Away From You
Many bonds include call provisions that let the issuer repay you early, and issuers exercise that option at the worst possible time for you. When rates fall, the issuer retires expensive old bonds and reissues at lower rates. You get your principal back, sometimes with a small premium, but now you have to reinvest in a lower-rate environment.4FINRA. Callable Bonds: Be Aware That Your Issuer May Come Calling The income stream you were counting on disappears exactly when alternatives are least attractive.
Some bonds carry make-whole call provisions instead of fixed-price calls. A make-whole call forces the issuer to pay the present value of remaining cash flows, discounted at a rate tied to comparable Treasury yields plus a small spread. Because that redemption price rises when rates fall, the issuer has little incentive to call. If call risk concerns you, look for make-whole language in the prospectus.
Bond Interest Is Taxed as Ordinary Income
Bond interest is taxed at ordinary income rates, not the lower long-term capital gains rates that apply to qualified stock dividends. In the 32% or 37% federal bracket, a meaningful share of your coupon goes to the IRS. A bond yielding 5% might net only 3.2% after federal taxes at the top bracket, and that’s before state income tax.5Internal Revenue Service. Publication 550 (2024), Investment Income and Expenses
Municipal bonds are the main exception. Interest on bonds issued by state and local governments is excluded from federal income tax.6Office of the Law Revision Counsel. 26 U.S. Code 103 – Interest on State and Local Bonds That exclusion doesn’t cover every muni. Private activity bonds that don’t qualify as exempt are treated as a preference item for the Alternative Minimum Tax, so higher-income investors can still owe tax on interest from certain municipal bonds.7Office of the Law Revision Counsel. 26 U.S. Code 57 – Items of Tax Preference Munis from your own state are usually exempt from your state’s income tax too, but bonds issued by other states typically aren’t. These wrinkles can narrow or wipe out the yield advantage munis seem to offer on paper.
Selling Can Be Slow and Expensive
Stocks trade on centralized exchanges with transparent pricing. Most bonds don’t. They trade over the counter through dealer networks, which makes finding a buyer for a specific issue slower and more expensive. High-yield corporates, small municipal issues, and anything off the beaten path often carry wide bid-ask spreads, sometimes several percentage points. In a period of market stress, when dealers pull back, you can take a haircut well beyond what the bond’s credit risk alone would justify.
Government bonds and large investment-grade corporates trade with reasonable liquidity. The further you move from those benchmarks, the worse it gets. The illiquidity premium is theoretically priced into the yield at purchase, but it becomes a real problem when plans change and you need the money back.
Bond Funds Add Risks You Don’t Get With Individual Bonds
Many investors buy bonds through mutual funds or ETFs, and that introduces risks that don’t exist when you hold a bond directly. The biggest one is maturity. When you hold an individual bond to maturity, you get your principal back regardless of what rates did along the way. A bond fund has no maturity date. It’s constantly buying and selling, so if rates rise and stay high, the fund’s net asset value can stay depressed indefinitely, and there’s no guaranteed return of your original investment.
Fees compound the issue. The asset-weighted average expense ratio for bond mutual funds was 0.38% in 2024, and actively managed bond funds often charge more. Bond index ETFs average around 0.10%. Those fees come straight out of your yield. On a bond fund yielding 4%, a 0.38% expense ratio eats nearly a tenth of your income every year, and over a decade the drag adds up. Individual bonds don’t carry ongoing management fees, though you do pay a spread to the dealer when you buy or sell.
