A callable bond, also referred to as a redeemable bond, is a type of debt security that allows the issuer to redeem the bond prior to its maturity date. This financial instrument provides the issuing corporation the flexibility to pay off debts early, usually in response to fluctuations in market interest rates. When interest rates drop, companies can call their existing bonds and issue new ones at lower rates, effectively refinancing their debt. In exchange for this callable feature, investors receive a higher coupon or interest rate than that offered on non-callable bonds.

Key Takeaways


How Callable Bonds Work

Callable bonds function as debt instruments wherein the issuer reserves the right to return the principal amount to investors and cease interest payments before the bond's maturity date. Companies often issue these bonds to fund expansion endeavors or pay down existing loans. When market conditions suggest falling interest rates, an issuer may choose to make their bonds callable, permitting early redemption to take advantage of lowered borrowing costs.

The specifics of a callable bond—including the terms of when the issuer can recall the bond—are outlined at the time of issuance. For example, a bond with a par value of $1,000 may be callable at 102, meaning that if the issuer calls the bond early, they would pay the bondholder $1,020. The ‘call price’ typically adjusts downward if the bond remains outstanding for a longer time, thus economics dictate the issuer's exercise of this option.


Types of Callable Bonds

Optional Redemption

With optional redemption, an issuer can redeem its bonds at specific times defined at issuance. Many municipal bonds and corporate bonds feature this option, while Treasury bonds tend to be non-callable.

Sinking Fund Redemption

Some callable bonds come with what is known as a sinking fund, wherein the issuer is obligated to pay back portions of the debt according to a set schedule. This method is beneficial as it allows companies to gradually reduce their debt obligations over time.

Extraordinary Redemption

Certain callable bonds feature extraordinary redemption rights, enabling issuers to call their bonds upon the occurrence of specific events, such as loss or damage to the underlying funded project.

Call Protection

Call protection refers to a period during which a callable bond cannot be redeemed. Understanding this timeframe and the specific call terms is crucial for investors considering callable bonds.


The Relationship Between Callable Bonds and Interest Rates

Although callable bonds may appear attractive due to their higher yields, they can expose investors to reinvestment risk. When interest rates fall after a callable bond is issued, the company may opt to call the bond and refinance with cheaper debt, costing the investor the future interest payments they would have received.

For instance, if an investor holds a callable bond with a 6% coupon but finds the bond called when interest rates drop to 4%, they will be forced to reinvest their capital at the new, lower rate. This could lead to a scenario in which the investor has difficulty matching the original coupon rate, resulting in lost potential income.

Example of a Callable Bond

Consider a scenario in which a company like Apple Inc. issues a 6% coupon bond worth $10 million, maturing in five years. Each year, Apple pays $600,000 in interest to bondholders. If interest rates fall to 4% three years later, Apple may choose to call the bond, compensating investors $10.2 million (including a premium of 2% over the par value).

By calling the bond, Apple can borrow from the bank at the new rate of 4%. The result allows the company to lower its annual interest payment from $600,000 to $408,000—demonstrating a significant savings over time.


In conclusion, callable bonds serve as a double-edged sword; they provide flexibility for issuers and higher yields for investors, but they also introduce risks that should be carefully considered. Investors looking to hold a stable income-producing asset may want to approach callable bonds with caution, weighing their financial objectives against the potential for reinvestment risk.
