How do perpetual bonds work?

Understanding How Perpetual Bonds Work

A perpetual bond, also known as a perpetuity or a ‘consol’, is a special type of bond that has no maturity date; it goes on indefinitely; in theory, its payments continue perpetually. These bonds were introduced initially because governments wanted to fund their operations without worrying about repaying the principal amount at any point.

Basic Features of Perpetual Bonds

Perpetual bonds have a few distinctive features that set them apart from other bonds:

1. No Maturity Date

The most notable feature of a perpetual bond is that it doesn’t have an expiration date. Once an investor purchases a perpetual bond, they can hold onto it indefinitely.

2. Fixed Interest Payments

Perpetual bonds make regular interest payments, also known as the coupon payment, throughout their unlimited life.

3. No Repayment of Principal

Since there is no maturity date for these bonds, the issuer does not have the obligation to repay the principal amount to the bondholders.

4. Subordination

Perpetual bonds are usually subordinate. In a liquidation scenario, they stand below other senior notes and debt instruments in preference for claims.

How Does a Perpetual Bond Function?

While a perpetual bond may seem like a complex financial instrument, its functioning is rather straightforward and involves some basic principles.

1. Issuance

An organization, which could be a business or a government agency, first issues a perpetual bond in order to raise money for its operations. The bond comes with a fixed interest rate, also known as the coupon rate, which remains unchanged for the bond’s lifetime.

2. Interest Payments

After an investor purchases a bond, the issuer pays them regular interest payments—typically annual or semi-annual ones. The yield of a perpetual bond is essentially the difference between the interest payment and the price. Since the price of perpetual bonds in the secondary market can fluctuate significantly because of macroeconomic conditions, the yield at the time of buying may be very different from the initial coupon divided by the original issue price.

3. The Hold

Investors typically hold perpetual bonds for an extended period of time. It offers them a constant income source, as the bonds produce consistent interest payments.

4. Transfer of Ownership

Though the issuer doesn’t have the obligation to repay the principal amount, the original investor can transfer ownership of the bond by selling it to another investor. Therefore, while the bond lives forever, its ownership can change hands.

Advantages and Disadvantages of Perpetual Bonds


1. Regular income

For the investor, perpetual bonds can serve as a reliable source of regular income in the form of interest payments.

2. No repayment pressure

For the issuer, the absence of a maturity date and no obligation to repay the principal amount make perpetual bonds a debt instrument with less pressure.


1. Interest rate sensitivity

Perpetual bonds are highly sensitive to interest rate changes. If interest rates in the economy rise, the prices of existing perpetual bonds will fall because they pay fixed interest.

2. Lack of principal repayment

For the investor, while the regular interest income is positive, they must also acknowledge that there will never be a principal repayment.

Are Perpetual Bonds Right for You?

The decision to invest in perpetual bonds depends on individual investment goals, risk tolerance, and overall portfolio strategy. If consistent income and long-term commitment align with your investment objectives, perpetual bonds could be a fitting addition to your portfolio. If, however, your strategy demands higher liquidity, short-term yields, or capital appreciation through principal repayment, standard fixed-income securities like regular bonds might be a better choice.

Final Thoughts

Perpetual bonds provide a unique opportunity for investors to secure a constant income stream. Its unique features make it an important instrument in the bond market, adding diversity and depth. However, understanding its intricacies and risk profile is key to using this tool effectively for wealth creation and capital preservation. Always consult with a trusted financial adviser or conduct thorough research to make informed investment decisions.
