Bond Maturity

Bond maturity is the expiration date of the contract. On that date, the company pays back the full principal amount, and the bond ceases to exist. Until then, the bondholder collects periodic interest payments. Maturity ranges from a few months to 30+ years, and the longer the maturity, the more interest-rate risk you shoulder and the higher the yield you should demand.

Why maturity matters

Maturity is the bond’s time horizon. A one-year bond gives you certainty that your principal is returned in 12 months; a 30-year bond exposes you to decades of interest rate and credit risk. If you buy a 30-year bond at 4% and interest rates rise to 6%, the bond’s market price falls sharply because new bonds offer better terms. You’re locked into a lower coupon, and to exit early, you must take a loss. This is interest rate risk, and it grows with maturity.

Issuers typically pay higher yields on longer-dated bonds to compensate for this risk. A 2-year corporate bond might yield 3%, while a 10-year bond yields 4.2%, and a 30-year bond yields 5%. The difference is the term premium—compensation for lending over a longer horizon.

Corporate maturity conventions

Most corporate bonds are issued with maturities of 3 to 10 years. Longer-dated corporates (20+ years) are rarer because companies face higher refinancing risk—the possibility that when the bond matures, they’ll have to roll over debt at much higher rates. Perpetual bonds—bonds with no maturity date—exist but are unusual; investors are wary of lending indefinitely.

The bond indenture specifies the exact maturity date. Bonds are often referred to by maturity in shorthand: “2030 bonds” are due in 2030, “10-year bonds” mature 10 years from issuance. As the bond ages, it “rolls down the yield curve,” meaning its yield and price change as it approaches maturity.

The path to maturity

As a bond ages, its maturity shortens. A 10-year bond issued today is a 9-year bond next year, an 8-year bond two years from now. This has practical effects:

1. Price behavior. All else equal, a 5-year bond is less sensitive to interest-rate changes than a 15-year bond. As your bond approaches maturity, its price becomes more stable because the principal repayment is imminent.

2. Refinancing opportunity. If interest rates have fallen, the company may exercise a call option before maturity and refinance at a lower rate. Bondholders lose the benefit of a high coupon.

3. Credit watching. Investors watch maturity clusters. If many bonds of one issuer all mature in 2027, there’s a “maturity wall”—the company must refinance a lot of debt at once, which can be risky in a stressed credit environment.

Bullet bonds vs. amortizing bonds

Most corporate bonds are “bullet” bonds: they pay interest regularly and return the full principal on one date (maturity). Some companies issue “amortizing” bonds that return principal gradually over the bond’s life—less common in corporate markets, more common in asset-backed securities.

Early redemption and maturity

Companies often reserve the right to call (redeem) bonds before maturity, typically 5+ years after issuance. The indenture specifies the call schedule and any premium (call price) the company must pay. Early redemption means the bondholder’s expected maturity is uncertain—the bond might be called at par if rates fall enough to make refinancing attractive.

Conversely, putable bonds give the bondholder the right to force the issuer to repay before maturity under specified conditions (e.g., a credit rating downgrade). This shifts maturity risk to the issuer.

Maturity and credit rating

Shorter maturities generally carry lower credit risk because repayment is sooner. A junk-rated company’s 2-year bonds are safer than its 10-year bonds—less time for the company to deteriorate. This is why yield curves for high-yield bonds are often steep: long maturity demands significant yield premium.
