What Is a Perpetual Bond?
A perpetual bond is a bond with no scheduled maturity date. Unlike a conventional bond, it does not have a set date when the issuer is required to repay the par value, unless the bond is called, redeemed under a special feature, or otherwise retired according to its terms.
Perpetual bonds can continue paying interest indefinitely. That makes them resemble a long-running income stream, but they still carry issuer risk, interest-rate risk, liquidity risk, and call-feature risk.
Key Takeaways
- A perpetual bond has no fixed maturity date.
- The issuer generally is not required to repay principal on a scheduled date.
- Many perpetual bonds include call features that let the issuer redeem them under stated terms.
- Perpetual bonds can be sensitive to interest-rate changes because their cash flows may extend far into the future.
How the Structure Works
A traditional bond has a maturity date. At maturity, the issuer repays the bond's par value, assuming no default and no earlier call or redemption. A perpetual bond removes that scheduled end date. The investor may receive coupon payments for as long as the bond remains outstanding.
The lack of maturity changes the risk profile. The investor cannot rely on a future maturity date to get principal back from the issuer. Selling in the secondary market may be the only practical way to exit unless the bond is called.
Feature | Conventional Bond | Perpetual Bond |
|---|---|---|
Maturity date | Has a scheduled maturity date. | No scheduled maturity date. |
Principal repayment | Usually due at maturity. | Generally not due on a fixed date. |
Interest payments | Paid until maturity or redemption. | May continue indefinitely if the bond remains outstanding. |
Exit path | Hold to maturity, sell, or face call risk. | Usually sell or wait for a call/redemption feature. |
Income and Price Risk
Perpetual bonds can appeal to investors seeking income, especially when coupons are higher than those on shorter-maturity debt. The tradeoff is duration-like sensitivity. Because principal repayment is not scheduled, price can be highly sensitive to changes in interest rates, credit spreads, and issuer health.
Call features can also shape returns. If rates fall, an issuer may redeem a callable perpetual bond and refinance at a lower cost, limiting the investor's upside. If rates rise or credit weakens, the bond may remain outstanding while the market price falls.
What to Read in the Terms
The prospectus or offering document is essential. Investors should review coupon terms, call dates, deferral rights, subordination, capital treatment, tax treatment, and whether missed payments are cumulative or discretionary.
Perpetual does not mean risk-free income forever. It means there is no ordinary maturity date, which makes the contract terms and issuer quality especially important.
The Bottom Line
A perpetual bond has no scheduled maturity date, so its value depends heavily on coupon terms, issuer strength, interest rates, liquidity, and call provisions. The income can be attractive, but the missing maturity date changes the risk.
