When interest rates rise, the market prices of existing bonds fall. A bond locked into a 3% coupon can’t compete with newly issued bonds paying 5%, so its secondary-market price drops until a new buyer’s effective return lines up with current rates. The size of the drop depends mostly on how long the bond has left to run, and the loss only turns into a real loss if you sell before the bond matures.
Why Rising Rates Push Bond Prices Down
A bond’s coupon is set at issuance and never changes. A $1,000 bond with a 4% coupon pays $40 a year for its entire life, regardless of what the Federal Reserve does afterward. When the Federal Open Market Committee raises its target rate, newly issued bonds come to market with higher coupons to match. Older bonds are suddenly competing against fresher alternatives that pay more.{1Federal Reserve. Federal Open Market Committee}
Nobody will pay full face value for a 3% bond when a comparable new bond pays 5%. The older bond’s price falls until that same $40 coupon represents a competitive return for a new buyer. The bond itself hasn’t changed; the issuer still owes the same payments on the same schedule. What changed is the opportunity cost of holding it, and the market prices that gap almost instantly.{2TreasuryDirect. Understanding Pricing and Interest Rates}
A quick example. If you paid $1,000 for a 4% bond that now trades at $920, a new buyer collecting the same $40 coupon is earning a current yield of about 4.35%. The discount is what compensates them for the below-market coupon. The reverse happens when rates fall: an older bond with an above-market coupon trades above face value, at a premium.
How Much Prices Fall: Duration and Maturity
Not all bonds react the same way. A 30-year bond will lose far more market value than a 2-year note for the same rate increase, because being locked into a below-market rate for three decades is a much bigger penalty than being locked in for two years.
Duration is the number that measures this. It estimates how much a bond’s price will move for each 1% change in interest rates. A bond with a duration of 5 drops roughly 5% in price if rates rise by 1%. A bond with a duration of 18 drops roughly 18%.{3FINRA. Brush Up on Bonds: Interest Rate Changes and Duration} Long-term Treasuries commonly carry durations in the high teens or low twenties, so a 1% hike can erase nearly a fifth of their market value. Short-term notes barely move.
This is where most investors underestimate their risk. A bond fund holding long-duration securities can swing in value like a stock portfolio during an aggressive hiking cycle. Funds with significant debt holdings report interest rate sensitivity data to the SEC on Form N-PORT, including projected portfolio value changes from a 1% rate move.{4U.S. Securities and Exchange Commission. Form N-PORT} That filing tells you more about a fund’s rate risk than its name does.
Zero-Coupon Bonds Are the Extreme Case
Zero-coupon bonds pay no interest along the way. You buy them at a deep discount and collect the face value at maturity. Because there are no coupon payments to partially offset rate changes, the bond’s duration equals its full maturity. A 20-year zero has a duration of 20, making it far more volatile than a 20-year bond paying regular interest. When rates rise, zeros lose more than coupon-paying bonds of the same maturity.
What This Does to Yield
Current yield (coupon divided by price) only tells part of the story. If you buy a bond at $920 and hold it to maturity, you also get the full $1,000 face value back. That extra $80 is a gain current yield doesn’t capture.
Yield to maturity accounts for everything: coupon payments, the time remaining, and the difference between what you paid and what you’ll receive at maturity. When rates rise and prices fall, yields to maturity on existing bonds rise to match the new environment. Two bonds with very different coupons and prices can end up with nearly identical yields to maturity if their credit quality and time horizons are similar. The market uses yield to maturity as the great equalizer, which is why experienced bond investors watch it rather than the coupon rate on the face of the bond.
If You Hold Until Maturity, the Paper Loss Disappears
This is the part that calms most investors down. If you hold a bond until it matures and the issuer doesn’t default, you get the full face value back. Every dollar of price decline you see on your statement is a paper loss that evaporates at maturity. A $1,000 bond that dropped to $850 on the secondary market still pays $1,000 when the term ends.
The loss only becomes real if you sell early. Secondary-market prices reflect what another investor would pay today, factoring in current rates.{3FINRA. Brush Up on Bonds: Interest Rate Changes and Duration} If you don’t need the cash before the bond matures, those interim swings are noise. This is one reason financial professionals distinguish individual bonds from bond funds. A bond fund never matures, because the manager continuously buys and sells, crystallizing gains and losses that an individual bondholder could simply wait out.
The flip side is reinvestment risk. While you’re collecting that locked-in 3% coupon for the next fifteen years, market rates might stay at 5% or higher. You’ll get your principal back eventually, but you’re earning less than you could in the meantime.
Rising Rates Can Also Pressure Credit Quality
Falling prices aren’t the only risk when rates rise. Higher borrowing costs squeeze companies that need to refinance debt. Firms operating on thin margins, especially smaller and heavily leveraged ones, feel the pressure first, and credit downgrades or outright defaults become more common in prolonged high-rate environments.
Investment-grade bonds from stable issuers tend to weather this with minimal damage. High-yield bonds (sometimes called junk bonds) are a different story. They already carry elevated default risk, and higher borrowing costs make that risk worse. On price alone, high-yield bonds are sometimes less sensitive to rate changes because their shorter durations and larger coupons cushion the blow, but credit losses can easily swamp that cushion if the issuer’s finances deteriorate. Chasing yield without watching credit quality is one of the most common mistakes during rate-hiking cycles.
Tax Consequences If You Sell at a Loss
Selling a bond for less than you paid creates a capital loss that offsets capital gains elsewhere in your portfolio. If your losses exceed your gains for the year, you can deduct up to $3,000 of the remainder against ordinary income ($1,500 if married filing separately). Anything left over carries forward to future tax years indefinitely.{5Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses} Bonds held one year or less produce short-term losses; those held longer produce long-term losses.{6Internal Revenue Service. Topic No. 409, Capital Gains and Losses}
The Wash Sale Rule
If you sell a bond at a loss and buy a substantially identical one within 30 days before or after the sale, the IRS disallows the loss.{7Office of the Law Revision Counsel. 26 U.S. Code 1091 – Loss From Wash Sales of Stock or Securities} The disallowed loss isn’t permanently lost; it gets added to the cost basis of the replacement bond, deferring the tax benefit rather than destroying it. “Substantially identical” is the phrase that trips people up. Two bonds from the same issuer with the same coupon and maturity would almost certainly qualify. Bonds from different issuers with different terms generally wouldn’t.
Market Discount Is Taxed as Ordinary Income
Here’s a trap specific to buying bonds that fell in price because rates rose. Any gain up to the amount of the accrued market discount is treated as ordinary income when you sell or redeem the bond, not as a capital gain.{8Office of the Law Revision Counsel. 26 U.S. Code 1276 – Disposition Gain Representing Accrued Market Discount Treated as Ordinary Income} Ordinary rates can be significantly higher than long-term capital gains rates, which erodes some of the apparent bargain in buying a discounted bond.
There’s one narrow exception. If the discount is less than 0.25% of face value multiplied by the number of years remaining to maturity, the IRS treats it as negligible, and the entire gain is capital. For a $1,000 bond with ten years left, that threshold is $25.
What You Can Do About Rate Risk
Knowing that prices fall when rates rise is only useful if you can act on it. Several approaches reduce rate sensitivity without abandoning fixed income.
Bond Ladders
A bond ladder spreads your money across bonds maturing at regular intervals: one year, two, three, and so on. When the shortest bond matures, you reinvest at the long end. In a rising-rate environment, that means you’re regularly freeing up capital to put to work at higher rates. You won’t capture the top rate on your whole portfolio at once, but you also won’t be stuck with everything locked in below market. The strategy works on the assumption that nobody can predict rates reliably, and the evidence supports that assumption.
Treasury Inflation-Protected Securities
TIPS adjust their principal based on changes in the Consumer Price Index. When inflation pushes rates higher, the principal on your TIPS rises, and your fixed coupon rate applies to that larger principal. At maturity you receive either the inflation-adjusted principal or the original face value, whichever is greater.{9TreasuryDirect. Treasury Inflation-Protected Securities (TIPS)} TIPS don’t eliminate rate risk entirely. If rates rise for reasons other than inflation, TIPS prices can still drop on the secondary market. But when inflation is driving the rate increases, TIPS hedge in a way conventional bonds cannot.
Floating-Rate Notes
Floating-rate notes reset their interest payments periodically rather than paying a fixed coupon. Treasury floating-rate notes tie their rate to the most recent 13-week Treasury bill auction and reset weekly.{10TreasuryDirect. Floating Rate Notes (FRNs)} When rates rise, the coupon rises with them, so there’s little reason for the price to drop. The tradeoff is giving up the upside of locking in a high fixed rate before rates fall.
Shortening Duration
The simplest move is shifting toward shorter maturities. A portfolio concentrated in bonds maturing within one to three years will barely flinch when rates move. You give up the higher yields longer maturities offer, but you gain the ability to reinvest frequently at whatever rates prevail.
A Note on Callable Bonds
Some bonds let the issuer repay early, usually when rates drop so the issuer can refinance more cheaply.{11U.S. Securities and Exchange Commission. Callable or Redeemable Bonds} When rates are rising, issuers have no reason to call, so callable bonds behave like regular bonds in that environment. The call feature becomes a non-issue, and you keep collecting the coupon for the full term.
