What are Perpetual Bonds?

perpetual bond, or a perp bond, is an irredeemable bond with a perpetual fixed income. In other words, it is a bond with no maturity date and cannot be redeemed. The purpose of a perpetual bond is to earn regular interest income perpetually, i.e. Therefore, these bonds do not have a maturity date or a maturity value.

Like dividends from equity shares, perpetual bonds also indefinitely provide regular income. Therefore, perpetual bonds are sometimes considered a part of equity, and their prices are determined akin to equity shares. Moreover, perpetual bonds create a perpetual debt obligation for the issuer, only in name, as the issuer does not have to repay the amount.

Why invest in Perpetual Bonds in India?

An investment in a perpetual bond is a guaranteed way to earn a fixed income. The secured income is usually for a more extended period since such bonds lack maturity feature. Not to mention, the return on investment on such bonds is more than other investment tools available in the market.

Here are the three primary reasons to invest in a perpetual bond:

Fixed Income Opportunity

Such bonds are the primary source of earnings for an investor looking for a source of fixed income. Such investment does not have any maturity. Hence, the interest earned from a perpetual bond is repetitive.

Increased Yield

Investing in perpetual bonds in India is acknowledged as an investment that provides higher returns. Such returns are in the form of interest. As a perpetual bondholder, you can receive interest forever as coupon payments.

Perpetual Bonds Taxes

The annual perpetual bonds coupon are added to the total income of an investor and then taxed accordingly, as per the Income Tax slab. However, if the investor earns a long-term capital gain (after a holding period of 1 year) while the bond is sold in the secondary market, then tax is applicable.

The long-term capital gains tax will be levied at 10% minus indexation.

Note: Due to the rise in inflation, investors are stepping back from the equities market to a more secure fixed source of income. Long-dated perpetual bonds with higher yields are the preferred option for such investors.

What You Need To Know Before Investing in Perpetual Bonds

With time, perpetual bonds have gained popularity among individual investors. However, there are certain risks involved that you need to know before investing in such bonds.

Redemption Uncertainty

A perpetual bond is an exclusive investment that varies from other kinds of fixed-income products and where redemption is an uncertain element.

The redemption usually happens with the consent of the issuer, however, it is influenced by certain market factors like present bond price, interest rate level, bond structure, etc.

Lack of Voting Rights

The majority of perpetual bonds are considered equity, according to accounting standards. It is because coupons are paid out periodically, and redemption is not guaranteed.

The holders of bank equity or company can vote on matters that need shareholder input. However, bondholders do not enjoy such privilege, even with perpetual bonds.

Subordinated Nature of Perpetual Bonds

The superiority of a bond evaluates the priority where investors are repaid if an issuer defaults or moves into liquidation.

Equity products and fixed income can be categorized as per their repayment priority, and the senior secured bonds are entitled to get paid first during liquidation or bankruptcy.

Discretionary Coupons 

Due to discretionary coupons, bond issuers can pay coupons at their convenience without compulsion. Investors who buy bonds integrated with such a feature are entitled to the risk of not getting a coupon payment during the bond tenure.

Why Do Banks Issue Perpetual Bonds in India?

Banks issue perpetual bonds in India to address long-term capital requirements. As per the features of such bonds, banks pay the perpetual bonds last during liquidation before equity investors. In banks, such bonds fall under the Additional Tier I bonds.

The coupon payment for such bonds is based on the issuing bank’s present-year profitability. The capital adequacy ratio that an issuing bank needs to maintain is 10.875% (minimum) with a Capital Conservation Buffer of 1.87%.

Note: The yield of perpetual bonds is higher than 200 points compared to government bond yields.

Looking at Perpetual Bonds with the aid of an Example

Perpetual bonds are priced similar to stock dividend payments. When transformed into a formula, the current value of a perpetual bond is:

Present Value = D/r


D = the applicable periodic coupon payment

r = the discount rate

For instance, if a perpetual bond pay USD 21000 every year as perpetuity when the discount rate is 3%, the current value will amount to:

Present Value = USD 21000 / 0.03 = USD 700,000.

Who Issues Perpetual Bonds?

How Does a Perpetual Bond work?

The concept of perpetual bonds is simple. These are perpetual debt instruments issued by government institutions or banks for the purpose of raising capital with a fixed interest or coupon rate. Individual investors purchase these bonds to receive a fixed income perpetually, i.e., till the issuer decides to redeem the bonds. In these types of bonds, the issuer is not required to repay the principal amount. Although perpetual bonds are a risk-free investment, they still carry a credit risk for the investors. Moreover, there is a risk of the investor losing the investment value if the market interest rate becomes more than the bond’s coupon rate. To counter this risk, some issuers may offer to increase the coupon rate after a fixed number of years, depending on the market rates.

Although perpetual bonds are very different from equity in various aspects, they still resemble equity more than debt. Therefore, they are considered to be a part of equity. It is important to note that the issuer has an option to redeem the bonds after the specified time has passed. This provides the issuer with the flexibility to redeem the bonds at their convenience, making it the most sought-after option to raise finance for the issuer.

The yield of a perpetual bond on the current date can be calculated by dividing the annual coupon payment by the market price of the bond. Further, multiply the figure with 100 to express it in terms of percentage.

Here is an example –

For instance, you purchased an Rs.1000 bond at a discounted rate of Rs. 850. The annual interest income received on the bond is Rs. 80. Then, the yield will be calculated as follows –

(80/850)*100 = 9.41%

Calculating the Yield on a Perpetual Bond

Investors can determine the yield to understand what to expect from a perpetual bond:

The yield on a perpetual bond = Periodic Coupon Payment/ Market Price of a bond.

Here is an example for a better understanding. You have spent money on a perpetual bond with a par value of 2000 by buying the bond at a rebate of Rs. 1950. You get coupon payments of Rs. 90 each year.

Current Yield = 90/1950 *100

= 0.046 *100

=4.6 %

The current yield of the bond is 4.6%.
