What it means
A conventional bond normally has a stated maturity and principal repayment obligation at that date. A perpetual bond lacks that scheduled endpoint.
An investor therefore cannot plan recovery of principal from a maturity date that the contract does not contain. FINRA's bond-data glossary explains that perpetual bonds have no set redemption date but may include call or other redemption features.
Unless redeemed under applicable features, the issuer is not required to pay the par value on a scheduled date. Check the actual terms rather than assume principal is permanently forbidden from returning.
An issuer call is an option for the issuer, not an investor's promise of repayment. The first permitted call date is not the same thing as maturity.
If the issuer does not call, the investment can continue under its terms. A holder wishing to exit may need to sell in the secondary market if no holder-redemption right exists.
The price can be below face value, and liquidity can be poor. A quoted market price does not ensure a large holding can be sold promptly at that level.
Payment terms need separate review, since some securities permit interest deferral or have other conditional coupon features, and the word bond should not cause a reader to ignore those provisions or assume every missed payment has the same consequences as a conventional debt default. A 2008 SEC-filed capital-security prospectus illustrates this combination: no fixed maturity, issuer redemption provisions, coupon deferral, and no holder right to redeem at will.
It is an example of specified terms, not evidence that every perpetual instrument has those exact features. Long-lived payments are sensitive to discount rates.
When the required return rises, the present value of a fixed payment stream falls. Inflation can also reduce the purchasing power of fixed nominal coupons even if they continue to be paid.
In practice
Real-world examples.
Example
A perpetual bond permits its issuer to call after five years. An investor enters that date in the cash forecast as guaranteed principal repayment.
Example
A holder needs cash and sells a perpetual bond below face value. The instrument has no holder redemption right and no scheduled maturity.
Example
A security's prospectus permits coupon deferral under specified conditions. The investor initially expects the same uninterrupted cash schedule as an ordinary fixed-maturity bond.
Formula
Calculation
For a simplified level annual perpetuity with the first payment in one year, present value = annual payment / required return, where the return is positive and expressed as a decimal.
A $60 annual payment at a 6% required return has an illustrative value of $60 / 0.06 = $1,000. At 8%, the value falls to $60 / 0.08 = $750, a $250 decline, or 25% of the starting value. If the required return fell to 5%, the value would rise to $60 / 0.05 = $1,200.
This assumes uninterrupted fixed payments and ignores call, reset, default, deferral, taxes, and liquidity. Those features must be considered before treating the model as a real security price.Case study
Seen in the real world.
Fictional case study: Fieldstone Treasury buys a perpetual security for income and expects redemption at its first call date. The issuer leaves it outstanding, while market-required returns have risen. Fieldstone reviews the prospectus and realises its cash plan relied on an issuer option rather than a contractual maturity. Selling would now produce less than the original investment, and coupon conditions also need to be reflected in future forecasts. The company changes its review checklist to record maturity absence, call rights, payment conditions, ranking, and exit liquidity separately.
The lesson is that a high coupon and a visible call date do not create the same cash certainty as a scheduled principal repayment. To see the scale, suppose Fieldstone holds 1,000 bonds with a $1,000 face value and a $60 annual coupon, so it receives $60,000 a year and paid $1,000,000. If the required return rises from 6% to 8%, the simplified value of each bond falls to $750, so the holding is worth about $750,000, a paper loss of $250,000. The coupons continue, but the cash from a sale would not match the original investment.
Watch out
Common mistakes.
- Treating the first call date as guaranteed maturity. The issuer can retain discretion under the instrument's terms.
- Assuming perpetual means risk-free endless income. Credit, payment conditions, inflation, and market rates still matter.
- Using the simple perpetuity formula as a complete market valuation. Structural features and liquidity can materially alter price.
Questions
People also ask.
Can a perpetual bond be redeemed?
Yes, if its terms permit redemption and the relevant conditions are met. No scheduled maturity is different from no possible redemption.
How can an investor exit?
Check holder rights and market liquidity. A secondary-market sale may be necessary and can return less than face value.
What should I read first?
The maturity, call, coupon, deferral, ranking, and holder-redemption provisions, together with issuer credit and the investment's fit with cash needs.
