Perpetual Bonds: Definition, Yield Calculation, Examples

Perpetual bonds, also known as "consol bonds" or "perps," are a unique type of fixed-income security that offers a continuous stream of income to investors. Unlike traditional bonds, perpetual bonds have no maturity date, making them an attractive option for investors seeking a steady and reliable income source. However, their lack of a redemption date also introduces specific risks and considerations. Let's delve into the world of perpetual bonds, exploring their definition, yield calculation, and examples.



Definition of Perpetual Bonds

Perpetual bonds are long-term debt instruments issued by governments, corporations, or other entities to raise capital. These bonds have no specified maturity date, allowing them to pay interest indefinitely. The issuer is not obligated to repay the principal amount, making perpetual bonds more akin to equity than debt. However, they are typically considered a hybrid security, combining characteristics of both debt and equity.

Yield Calculation of Perpetual Bonds

The yield calculation of perpetual bonds is influenced by several key factors, including the discount rate, coupon payment, market demand, credit risk, inflation, and subordination. The discount rate reflects the rate at which money loses value over time, primarily due to inflation. The coupon payment, or interest payment, is a fixed amount paid by the issuer to the bondholder. Market demand plays a crucial role in determining the bond's yield, as higher demand leads to a higher price and lower yield. Credit risk, inflation, and subordination also impact the yield of perpetual bonds.

The current yield and present value of the perpetual bond formula are as follows:

Present value = D / r
Where:
D = periodic coupon payment of the bond
r = discount rate applied to the bond

Current yield = Annual coupon payment / Market price

The price of a perpetual bond is calculated as the present value of the fixed interest income or periodic coupon payment (D), which is obtained by dividing D by the discount rate R.

Examples of Perpetual Bonds

1. British Government Perpetual Bond (Consol)
- Issuer: British Government
- Issue Date: 1888
- Features: The British Consol is one of the oldest perpetual bonds still in existence. It was issued with a coupon rate of 2.5% and has no maturity date. The British government has never redeemed these bonds, and they continue to pay interest indefinitely.
- Risks: As with any government bond, there is a risk of default. However, the British government has a strong credit rating, making this risk relatively low. Additionally, the bond's low coupon rate may not keep up with inflation, reducing the real value of the income received.

2. Enron Perpetual Preferred Stock
- Issuer: Enron Corporation
- Issue Date: 2001
- Features: Enron issued perpetual preferred stock with a coupon rate of 8.25%. These securities had no maturity date and paid dividends indefinitely. However, they were callable by Enron at any time, giving the company the option to redeem the stock.
- Risks: Enron's perpetual preferred stock was riskier than the British Consol due to the company's lower credit rating and the callable feature. When Enron faced financial difficulties in 2001, it called back the preferred stock, leaving investors with no further income and no principal repayment.

3. Hyundai Motor Company Perpetual Bond
- Issuer: Hyundai Motor Company
- Issue Date: 2014
- Features: Hyundai issued a perpetual bond with a coupon rate of 3.75% and a call option after 5 years. The bond had no maturity date, and the company was not obligated to repay the principal.
- Risks: Hyundai's perpetual bond carried credit risk, as the company's financial health could deteriorate, leading to a default on interest payments. Additionally, the call option allowed Hyundai to redeem the bond if market conditions improved, potentially leaving investors without further income.

Perpetual bonds offer a unique investment opportunity with a steady income stream, but their lack of maturity and subordinate position require careful consideration. Understanding their features and risks is essential for making informed investment decisions. By examining the examples above, investors can gain insight into the various aspects of perpetual bonds and their potential impact on a portfolio.
