Bullet Bond
A bullet bond is a fixed-income security that pays periodic coupon interest throughout its life and repays the entire principal in a single lump sum at maturity, with no scheduled principal amortization prior to the maturity date and no embedded call or put option allowing early redemption. It is the most straightforward and common bond structure in investment-grade corporate and government debt markets.
Key takeaways
- Unlike amortizing bonds (which return principal gradually) or callable bonds (which can be redeemed early), a bullet bond provides a single principal payment at maturity — making its cash flows fully predictable.
- The price sensitivity (duration) of a bullet bond is higher than an equivalent amortizing bond of the same maturity, because all principal is returned at the end, maximizing the time-weighted cash flows.
- Bullet structure is preferred by corporate issuers seeking to avoid refinancing risk during the bond's life and by investors who prefer predictable reinvestment timing and want to 'ride the yield curve.'
- The simplicity of bullet bond cash flows makes them the reference instrument for constructing yield curves and pricing other fixed-income instruments via bootstrapping.
- Bullet bonds can still be 'redeemed' through open-market purchases or tender offers by the issuer, but the holder has no obligation to participate — a key difference from callable bonds where the issuer has the right to force redemption.
Explanation
The bullet structure represents the 'plain vanilla' of fixed-income instruments. A company or government issues a bullet bond with a stated face value (par), a coupon rate (fixed, typically paid semiannually in the U.S. or annually in Europe), and a single maturity date. Cash flows consist of coupon payments at each scheduled coupon date and a final payment of the coupon plus the full principal at maturity. There is no optionality — the bond will pay exactly these cash flows barring default.
The bullet structure's simplicity has important portfolio implications. Because the full principal is returned at a known future date, portfolio managers can precisely match liabilities with bullet bond maturities — critical for pension funds, insurance companies, and defined benefit plans using liability-driven investment (LDI) strategies. A pension fund with $50 million of benefit payments due in 2030 can purchase $50 million face value of 2030 bullet Treasuries and eliminate reinvestment risk entirely on that tranche of liability.
Duration — the primary measure of interest rate sensitivity — is higher for bullet bonds than for structurally equivalent amortizing bonds. An amortizing bond that returns half its principal after 3 years and the remaining half after 7 years has an average maturity of about 5 years, similar to a bullet bond with a 5-year maturity — but the bullet bond has longer duration because its cash flows are more back-loaded. For a zero-coupon bullet bond (which pays no coupons at all), duration equals exactly the maturity, making it the purest expression of interest rate risk.
Issuers prefer bullet structures when they want to lock in long-term financing without facing refinancing requirements during the bond's life. A company that issues a 10-year bullet bond in a favorable rate environment knows its entire principal obligation is due in 2034, allowing its treasury to plan cash flows accordingly. The bullet structure also avoids the complexity of callable bonds, which require embedded option valuation and create uncertainty about effective maturity and yield. Investment-grade corporate issuers predominantly use bullet structures for their benchmark debt issuances; high-yield issuers frequently include call provisions, making true bullet bonds less common in the speculative-grade universe.
Formula
Price = Σ [C / (1+y)^t] + [F / (1+y)^T] Where C = coupon payment, F = face value, y = yield to maturity, T = maturity Modified Duration = Macaulay Duration / (1 + y/m)
Example
Apple Inc. issued a $2 billion 10-year bullet bond in September 2019 with a coupon of 2.200% due September 2029. Holders receive $22 per $1,000 face value every six months (0.011 × $1,000) from October 2019 through September 2029, plus a final payment of $1,022 at maturity. An investor who purchased $1 million face value at par receives $22,000 every six months for 10 years, with the full $1 million principal returned in September 2029. There is no uncertainty about cash flow timing (barring Apple default), no call risk, and no amortization to track — the pure bullet structure allows institutional investors to precisely model the bond's contribution to portfolio duration and carry.
