A term bond is a bond in which the entire principal is repaid on a single maturity date, while the issuer pays fixed interest to bondholders in the meantime.1National Association of Bond Lawyers. Maturity Date Corporations and municipalities use the structure to raise large sums for projects that take years to pay off, deferring the full repayment until the investment has had time to generate returns.
How the Structure Works
Every bond in a term issue shares the same maturity date. If a company sells $200 million in term bonds maturing in 2040, every bondholder receives principal back on that single date. Until then, the issuer pays interest at a fixed coupon rate, calculated as a percentage of face value. Corporate bonds typically carry a face value of $1,000 per bond.
Those coupon payments give you predictable income for the life of the bond. When the maturity date arrives, the issuer repays the full face value in one lump sum. For a large issue, that final payment can run into the hundreds of millions, which is why term bonds usually include contractual features designed to make the obligation manageable rather than leaving it all to the last day.
Term Bonds Compared With Serial Bonds
The clearest way to see what a term bond is is to set it against a serial bond. In a serial issue, the principal is split into portions that mature on a staggered schedule across multiple years.2National Association of Bond Lawyers. Serial Bonds A $100 million serial issue might retire $10 million each year for a decade, so the issuer’s outstanding debt steadily declines. A $100 million term issue requires the whole $100 million in one shot at the end.
That gap creates what is sometimes called balloon payment risk. A serial issuer proves its ability to repay every year; a term issuer does not face the real test until the final date. Investors in serial bonds watch the debt shrink. Investors in term bonds carry more concentration risk, which is why sinking funds exist.
Municipalities often blend the two in a single deal, using serial bonds for the early maturities and term bonds for the later ones.3MSRB. Municipal Bond Basics The serial portion starts generating repayment cash flows quickly while the term portion pushes the bulk of the debt further out, giving the funded project time to ramp up revenue.
Sinking Funds and Call Features
Because the whole principal is due at once, most term bond issuers don’t just wait for maturity day. The most common safeguard is a sinking fund provision, which requires the issuer to set aside money on a regular schedule, usually annually or semiannually, earmarked for retiring portions of the debt before the final date.4National Association of Bond Lawyers. Mandatory Sinking Fund Redemption
A trustee oversees these payments and uses the accumulated funds to buy back a set portion of the outstanding bonds each period. Bonds selected for early retirement are chosen at random, so you won’t know in advance whether your specific bonds will be called.4National Association of Bond Lawyers. Mandatory Sinking Fund Redemption The redemption price is typically face value plus accrued interest. For most issues held through the Depository Trust Company, this lottery-style selection is the default.
The sinking fund cuts both ways. It reduces the risk that the issuer can’t pay at maturity, because the outstanding balance shrinks over time. But it can also strip you of a bond paying an attractive coupon, with no say in the matter.
Beyond the mandatory sinking fund, many term bonds carry an optional call provision that lets the issuer redeem the whole issue before the stated maturity.5Investor.gov. Callable or Redeemable Bonds Issuers typically use this right when market interest rates drop below the coupon, allowing them to refinance more cheaply. Many municipal bonds become callable after ten years. The call price is usually set at or near face value plus accrued interest. Once bonds are called, interest payments stop and you receive the call price regardless of what you paid. If you bought the bond at a premium in the secondary market, a call can mean a loss.
Some corporate term bonds instead include a make-whole call, where the issuer pays a lump sum calculated to approximate the present value of the remaining interest payments plus principal, using a discount rate pegged to Treasury yields plus a spread specified in the indenture.6FINRA. Callable Bonds: Be Aware That Your Issuer May Come Calling The intent is to compensate you more fairly for early retirement, though the actual payout depends on market conditions at the time. Whichever call structure applies must be disclosed in the offering documents, so you can see before buying whether and when your bonds could be retired.5Investor.gov. Callable or Redeemable Bonds
The Main Risks
Interest Rate Risk
Bond prices move opposite to interest rates. When rates rise, your existing bond’s fixed coupon becomes less attractive next to new issues, and the market price drops. The longer the time to maturity, the sharper the swing.7FINRA. Duration – What an Interest Rate Hike Could Do to Your Bond Portfolio A term bond with 20 years remaining will lose far more market value from a one-percent rate increase than one maturing in three. Duration is the metric that captures this sensitivity; term bonds with long maturities and lower coupons carry the highest duration, and are among the most rate-sensitive fixed-income instruments. If you hold to maturity, daily price moves don’t affect your final return. If you may need to sell early, this is the biggest variable.
Credit Risk
Credit risk is the chance the issuer misses an interest payment or fails to repay principal at maturity. Other than U.S. Treasury securities, generally considered free of default risk, virtually all bonds carry some. Rating agencies grade this exposure: bonds rated BBB or above by Standard & Poor’s (Baa or above by Moody’s) are investment grade; anything below is high-yield, and those issuers pay higher coupons to compensate.8FINRA. Bonds
Credit risk matters more for term bonds than for serial bonds because the full principal stays outstanding for the entire life of the issue. With a serial bond, the issuer’s total debt shrinks each year, reducing your exposure. A term bond keeps your exposure at the maximum level until the sinking fund starts biting or maturity arrives.
Reinvestment Risk
If your term bond is called early through a sinking fund or an optional redemption, you get your principal back sooner than expected. That sounds like a win, but calls tend to happen when interest rates are falling, which is exactly when a comparable return is hardest to find. FINRA has noted that investors whose callable bonds get redeemed often face a meaningful gap in expected annual income when they reinvest at prevailing lower rates.6FINRA. Callable Bonds: Be Aware That Your Issuer May Come Calling That is the trade-off built into any callable term bond: lower default risk in exchange for less certainty about how long you’ll actually receive the coupon.
Tax Treatment
How your term bond income is taxed depends almost entirely on who issued it.
Corporate Term Bonds
Interest income from corporate bonds is taxed as ordinary income at your federal rate, and typically at the state level as well. If you bought the bond at a discount from face value in the original offering, the difference between what you paid and the face value is treated as original issue discount. The IRS requires you to recognize a portion of that discount as taxable income each year, even though you don’t receive the cash until maturity or sale.9Internal Revenue Service. Publication 1212, Guide to Original Issue Discount (OID) Instruments
Municipal Term Bonds
Interest on bonds issued by state and local governments is generally excluded from federal gross income.10Office of the Law Revision Counsel. 26 USC 103 – Interest on State and Local Bonds If you live in the state that issued the bond, the interest is often exempt from state income tax as well. That advantage is a big reason municipal term bonds can offer lower coupon rates than comparable corporate bonds and still attract buyers. To compare a municipal yield with a taxable alternative, you would calculate the tax-equivalent yield, which adjusts for the taxes owed on a corporate bond’s interest. For an investor in a high federal bracket, a municipal yield of 3.5% can be worth over 5% on a pre-tax basis.
Who Issues Term Bonds and Why
Corporations are the most frequent issuers. The structure fits well when a company needs to finance a large capital project, such as a new plant or an acquisition, that won’t generate cash flow right away. Pushing the full principal repayment into the future gives the investment time to start earning before the bill comes due.
Municipalities use term bonds alongside serial bonds in most large issuances.3MSRB. Municipal Bond Basics A city funding a toll road or water treatment facility might issue serial bonds for the first ten years and term bonds maturing at year 20 and year 30. The serial portion begins paying down debt as early revenue trickles in, while the term bonds give the project decades to reach full capacity before the largest payments come due. Municipal term bonds typically mature after about 20 years.
On the buy side, institutional investors, particularly pension funds and insurance companies, often favor term bonds because the long, predictable maturity date makes it easier to match assets against long-term liabilities. A pension fund that knows it will owe benefits in 2045 can buy a term bond maturing that year and lock in both the income stream and the return of principal.
