Putable bonds, also known as put bonds, are a type of bond that grants the bondholder the right to demand early repayment of the principal before the bond’s maturity date. This feature provides investors with a measure of protection against interest rate risk and credit risk. The concept of putable bonds dates back to the early 20th century when investors sought ways to mitigate risk during periods of economic uncertainty and market volatility.
Types/Categories of Putable Bonds
Putable bonds can be classified into several categories based on their characteristics and the conditions under which the put option can be exercised:
1. European Putable Bonds
These bonds allow the holder to exercise the put option only at specified dates, usually on an annual basis.
2. American Putable Bonds
American putable bonds give the holder the flexibility to exercise the put option at any time before the maturity date.
3. Bermudian Putable Bonds
These bonds offer a middle ground, allowing the holder to exercise the put option on predetermined dates.
Key Events
1. Introduction of Putable Bonds
The introduction of putable bonds provided investors with a new way to manage interest rate risk, especially during periods of high inflation in the 1970s.
2. Market Adaptation
Over the decades, putable bonds have become an important tool in fixed-income portfolios, particularly during times of economic downturns and volatile interest rates.
Detailed Explanations
Importance and Applicability
Putable bonds are essential for investors seeking safety and flexibility in their fixed-income investments. They are particularly attractive during times of rising interest rates, as they allow investors to reinvest in higher-yielding securities. Furthermore, they provide an additional layer of security in case the issuer’s creditworthiness deteriorates.
Mathematical Models
The pricing of putable bonds incorporates the valuation of the embedded put option. Theoretical models such as the Black-Scholes model and binomial models are often used for this purpose.
Black-Scholes Model for Putable Bonds
The Black-Scholes model can be adapted to value the put option in a putable bond. The key variables include the bond’s volatility, time to maturity, and the risk-free interest rate.

Examples
Real-World Example
Consider a bond issued by a corporation with a 10-year maturity and a 5% annual coupon rate. If interest rates rise significantly after five years, the bondholder can exercise the put option to get back the principal and reinvest at higher prevailing rates.
Considerations
1. Issuer Perspective
Issuers typically offer putable bonds with lower coupon rates than comparable non-putable bonds to compensate for the additional cost of the put option.
2. Investor Perspective
Investors should weigh the benefits of the put option against the lower coupon rate and potential reinvestment risks.
