Along with traditional fixed-income instruments, some investors now evaluate bonds to diversify their investment portfolios. Bonds are debt instruments and are of various types. Puttable bonds are one of them. A puttable bond gives investors the right to sell the bond back to the issuer before maturity on predetermined dates. This feature becomes useful when interest rates rise or market conditions change unexpectedly. Investors may prefer reinvesting funds into instruments offering better returns or lower credit risk exposure.
Understanding Puttable Bonds
A puttable bond, also called a put bond or retractable bond, includes an embedded investor protection feature. It gives investors the right to sell the bond back before the scheduled maturity date. However, investors are not obligated to exercise this option if market conditions remain favourable during tenure. This feature, called a put option, generally provides greater flexibility throughout the bond investment period.
In the case of a regular bond, a person receives interest payments as well as the face value upon maturity. Whereas, in a puttable bond, this structure continues, but with an additional exit feature at specific intervals. These intervals are defined at the time of issuance and are disclosed in the offer document.
For investors, this may be seen as a structured exit clause. The investor may choose to return the bond to the issuer rather than depending only on selling it on secondary markets such as the Bombay Stock Exchange (BSE) or the National Stock Exchange of India (NSE).
How Puttable Bonds Work
A puttable bond operates through predefined contractual terms that specify when and how the put option can be exercised.
The bond includes one or more “put dates” during its tenure. These dates are set in advance to provide structured exit opportunities. From an investor’s perspective, this reduces dependence on market liquidity for exit.
For example, a 7-year NCD issued in India may include a put option at the end of year 3 and year 5. On these dates, the investor can choose to continue holding the bond or exit by selling it back to the issuer. The investor’s decision usually depends on market conditions. Factors such as prevailing interest rates, alternative yields, and the issuer’s credit profile could influence this decision.
If interest rates in India rise after issuance, newer bonds may offer higher yields. In such a case, the investor may exercise the put option and reinvest elsewhere. Conversely, if rates fall, the investor may choose to continue holding the bond.
Importance of Puttable Bonds for Issuers and Investors
Puttable bonds provide flexibility to investors and funding access to issuers. There is an increasing demand for flexible securities among Indian investors, with an emphasis on balancing returns and liquidity.
For the investor, the put feature allows for an agreed exit strategy, which can help in dealing with interest rate cycles and credit perceptions. This usually reduces reliance on the secondary market, where liquidity can vary across issuances.
For issuers, including a put option may make the bond more attractive, particularly during periods of uncertainty. This can support subscription levels in primary issuances.
However, this flexibility introduces refinancing considerations for issuers. If many investors exercise the put option, the issuer may need to arrange funds earlier than the original maturity.
The structure may redistribute market exposure between the issuer and the investor. Investors gain optionality, while issuers take on timing-related repayment obligations. Both parties need to assess these trade-offs within their financial planning.
How to Find the Valuation of Puttable Bonds
Valuing a puttable bond involves adjusting the price of a regular bond to include the value of the embedded put option.
Vputtable = Vstraight + Vput option
Where:
Vputtable : Total value of the puttable bond
Vstraight : Value of an equivalent bond without the put option
Vput option: Value of the embedded put option
Example 1: Bond Trading at a Discount
Assume a bond has a face value of ₹1,000 and is currently valued at ₹970 as a regular bond without any special features. The embedded put option is estimated to be worth ₹40 because investors may benefit from selling the bond back to the issuer if market interest rates increase in the future.
Using the formula:
₹970+₹40=₹1,010₹970 + ₹40 = ₹1,010₹970+₹40=₹1,010
So, the total value of the puttable bond becomes ₹1,010.
Example 2: Bond Trading at a Premium
Assume another bond has a face value of ₹1,000 and the equivalent straight bond is valued at ₹1,030 because its coupon rate is higher than prevailing market interest rates. The embedded put option is estimated to be worth ₹40.
Using the formula:
₹1,030+₹40=₹1,070₹1,030 + ₹40 = ₹1,070₹1,030+₹40=₹1,070
So, the total value of the puttable bond becomes ₹1,070.
These examples show that a puttable bond may derive its value from either a discounted or premium-priced straight bond, with the embedded put option adding extra value in both cases.
Types of Puttable Bonds Available
Some common types of puttable bonds are:
Traditional Puttable Bonds
These are the most commonly used formats. In this structure, the bond includes one or more predefined put dates during its tenure. The investor can choose to sell the bond back to the issuer at these specific points, usually at face value.
In the Indian market, many non-convertible debentures (NCDs) follow this format, with terms disclosed in the offer document.
Example:
Let’s say an investor buys a 5-year non-convertible debenture worth ₹1,000 with a put option in the third year. In case the interest rate rises in the third year, the investor can invoke the put option and exit at ₹1,000 rather than waiting until the fifth year.
Extendable Puttable Bonds
These bonds combine a put option with an extension feature. In this structure, the investor has two choices at a predefined date:
- Exit the bond using the put option, or
- Continue holding the bond for an extended maturity period
If the investor chooses to extend, the bond may offer a revised coupon rate for the extended period. This reflects changing market conditions and compensates for the longer holding duration.
Example:
An investor holds a 4-year bond with a put option at the end of year the second year. In the 2nd year, the investor can exit or extend the bond to year 4 with a higher coupon rate. The decision may depend on prevailing yields and reinvestment options.
Advantages and Limitations of Puttable Bonds
Some benefits and limitations of puttable bonds are:
| Advantages | Limitations |
|---|---|
| Investors can exit at predefined dates instead of holding until maturity, which may help in managing changing market conditions. | The presence of a put option may lead to a lower Yield to Maturity (YTM) compared to similar non-puttable bonds. |
| The option to exit may limit exposure to interest rate changes or shifts in the issuer’s credit profile. | If the bond is exited early, reinvesting the proceeds may result in lower yields if market rates have declined. |
| Investors are not fully dependent on exchange liquidity to exit, especially when trading volumes are limited. | The put option is only available on certain dates, which cannot always match the demands of investors. |
| Investors can modify the duration and allocation of their portfolios in response to changing financial circumstances. | Compared to ordinary bonds, understanding embedded options, pricing, and value may take more research. |
| The functionality might make it easier for investors to react to situations where interest rates are rising. | The cost of flexibility may be taken into account by issuers, which may have an impact on coupon rates and total pricing. |
Things to Consider Before Investing in Puttable Bonds
Some important points that investors can review before investing are:
- Credit rating and financial strength of the issuer, as the put option does not eliminate default risk.
- Alignment with individual risk tolerance rather than focusing only on yield expectations
- Reinvestment risk if the put option is exercised, especially when interest rates are lower at the time of exit
- Tax treatment of coupon income and capital gains in India, which may vary based on holding period and investor profile
- Terms in the offer document, including put dates, coupon frequency, maturity, and conditions for exercising the option
- Diversification across issuers and sectors to reduce concentration risk within a fixed-income portfolio
These factors may help investors assess how puttable bonds fit within their broader investment approach and market conditions.
Conclusion
Puttable bonds give investors the option of selling the bond back to the issuer at predetermined intervals before maturation. This could influence how investors handle duration and liquidity in the Indian market, where interest rates and credit conditions change. The structure does, however, have trade-offs. Lower returns, time constraints, and reinvestment concerns could all have an impact on overall performance. So, understanding the link between the put option, yield, credit risk, and market conditions is important.
