The Option That Changes Everything

A callable bond gives the issuer the right to repay the bond before its maturity date, usually at a set call price after a period of call protection. A non-callable bond cannot be redeemed early, so the investor receives every coupon until maturity. Because the call option benefits the issuer, callable bonds pay a higher yield than otherwise identical non-callable bonds.

Issuers call bonds when interest rates fall, so they can refinance at a lower cost. That leaves the investor with cash to reinvest at the new, lower rates. Understanding that trade-off is the key to every question on the topic.

This comparison sits in the investment vehicle section of the exam and comes up again whenever an adviser recommends bonds to a client. For the full route from exam to registration, our complete guide to how to become an investment adviser representative covers every step.

How a Call Feature Works

A callable bond sets out its call terms in the bond’s indenture. The three terms that matter are the call protection period, the first call date and the call price.

The call protection period is the stretch, often five or ten years, during which the issuer cannot redeem the bond. After the first call date, the issuer may call the bond, usually at a price slightly above par to begin with, stepping down to par over time. A premium of two points, for example, means the issuer pays $1,020 for each $1,000 bond.

A non-callable bond, sometimes called a bullet bond, has none of these terms. The issuer repays the full face value on the maturity date and not before. United States Treasury bonds issued today are non-callable, which is part of why they serve as the benchmark for the whole market. The Series 65 Exam Preparation course at FRC sets out each of these terms with the worked yield calculations the exam expects.

Callable vs Non-Callable at a Glance

Why Issuers Call Their Bonds

Issuers call bonds for the same reason homeowners refinance mortgages. If a company issued bonds paying 6 percent and market rates fall to 4 percent, calling the old bonds and issuing new ones at 4 percent saves two percentage points of interest every year.

Issuers may also call bonds to remove restrictive covenants, to reduce debt after selling a business or to simplify their capital structure. Municipal issuers frequently call bonds after ten years when rates have fallen, and municipal bonds are among the most commonly callable securities an adviser will meet.

The decision is entirely the issuer’s. The investor cannot stop a call, which is why the call feature is described as an option the investor has effectively sold to the issuer.

Call Risk and Reinvestment Risk

Call risk is the risk that a bond is redeemed early, usually at the worst possible time for the investor. Bonds are called when rates have fallen, so the investor receives cash just when new bonds pay less.

That creates reinvestment risk. An investor counting on 6 percent for twenty years might find the bond called after seven, with only 4 percent available on comparable new bonds. The income stream the investor planned around disappears.

Non-callable bonds remove this particular risk. The investor knows exactly how long the coupon will last, which makes them valuable for planning, such as matching a bond’s maturity to a known future expense like a child’s tuition or a retirement date.

Price Compression: The Ceiling on Callable Bonds

When interest rates fall, bond prices rise, but callable bonds hit a ceiling. Investors will not pay much above the call price for a bond that is likely to be redeemed at that price soon.

Here is a worked example. Take a 6 percent bond with ten years to maturity. If market yields fall to 4 percent, a non-callable version rises to about $1,163.50 per $1,000 of face value. A callable version that can be redeemed at $1,020 in three years would trade at only about $1,073.80, because investors price it to the likely call.

When rates rise, the picture changes. At an 8 percent market yield, the issuer has no reason to call, and both bonds fall to about $864. The callable bondholder takes the full loss when rates rise but shares less of the gain when rates fall, an effect known as negative convexity. Our article on why bond prices fall when interest rates rise explains the underlying relationship.

Callable Bonds and Duration

Duration measures how sensitive a bond’s price is to changes in interest rates, and call features make it a moving target. A non-callable bond has a predictable duration that shortens steadily as it approaches maturity.

A callable bond’s effective duration changes with the market. When rates fall and a call becomes likely, investors treat the bond as if it matures on the call date, so its duration shortens and its price stops rising. When rates rise and a call becomes unlikely, the expected life extends towards final maturity and duration lengthens, just as prices are falling.

That combination is uncomfortable for investors: less price sensitivity when it would help and more when it hurts. Portfolio managers who need stable interest rate risk exposure often favour non-callable bonds for exactly this reason.

Yield to Call, Yield to Maturity and Yield to Worst

Callable bonds need more than one yield measure. Yield to maturity assumes the bond is held to its final date. Yield to call assumes it is redeemed on the call date at the call price.

Yield to worst is the lower of the two, and it is the figure regulators expect firms to quote on customer confirmations for callable bonds. It shows the investor the lowest return they could receive without the issuer defaulting.

Work through an example step by step. A $1,000 bond pays a 6 percent coupon, matures in ten years and is callable in three years at $1,020. It trades at $1,080.

Step one: the current yield is $60 divided by $1,080, or 5.56 percent. Step two: the yield to maturity, solved over ten years to a $1,000 repayment, is about 4.97 percent.

Step three: the yield to call, solved over three years to a $1,020 repayment, is about 3.79 percent. Step four: the yield to worst is the lower figure, 3.79 percent.

The Premium and Discount Rule

The order of yields follows a fixed pattern. For a premium bond, bought above par, the coupon rate is highest, followed by current yield, then yield to maturity, then yield to call. That matches the example above: 6 percent, 5.56 percent, 4.97 percent and 3.79 percent.

The premium is lost faster if the bond is called early, because the investor paid $1,080 and receives only $1,020 after three years rather than $1,000 after ten. Spreading a loss over fewer years cuts the annual return harder.

For a discount bond, bought below par, the order reverses. Yield to call is highest, then yield to maturity, then current yield, then the coupon rate. The discount is earned back faster if the bond is called early, which boosts the annual return.

The Memory Aid

Remember this line: the issuer calls when rates fall, and the investor reinvests at less. Every feature of a callable bond follows from it, from the higher yield that compensates investors, to the price ceiling, to the reinvestment risk.

For yield ordering, picture a seesaw. With a premium bond, the coupon sits at the top and yield to call at the bottom. With a discount bond, the seesaw tips the other way and yield to call rises to the top.

For the quoted yield, remember that “worst” means the lower of yield to call and yield to maturity. For a premium bond, yield to worst is almost always yield to call.

Exam Traps to Avoid

The first trap is assuming the investor controls the call. Only the issuer can call a bond. An option that lets the investor sell a bond back early is a put feature, and a putable bond pays a lower yield because the option benefits the investor.

The second trap is reversing the rate direction. Bonds are called when interest rates fall, not when they rise. A question describing rising rates is unlikely to involve an early call, and the correct answer will often point to extension of the bond’s expected life.

The third trap is choosing yield to maturity for a premium callable bond. When a question asks which yield is quoted, or which return is lowest, the answer is yield to call or yield to worst. The fourth trap is ignoring the call price: a call at $1,020 changes the yield to call calculation, so always use the stated call price rather than par.

A Client Scenario

A retired client wants dependable income and is choosing between two municipal bonds with similar credit quality. One is non-callable and yields 3.4 percent to maturity in fifteen years. The other is callable in five years and offers a yield to maturity of 3.9 percent, but a yield to worst of 3.1 percent because it trades at a premium.

The adviser explains that the higher headline figure on the callable bond is not the return to rely on. If rates fall, the bond is likely to be called in five years, the client would receive the call price and would have to reinvest at lower rates, and the realised yield would be closer to 3.1 percent.

For a client who needs certainty of income for fifteen years, the non-callable bond is the better fit. For a client comfortable with the possibility of early repayment, the callable bond may still suit. The decision turns on the client’s risk tolerance and need for predictable income, which is exactly what suitability requires the adviser to weigh.

Make-Whole Calls and Sinking Funds

Not every call feature hurts investors equally. Many investment grade corporate bonds carry a make-whole call, which lets the issuer redeem at any time but only by paying the present value of all remaining payments, discounted at a Treasury yield plus a small spread. The cost is usually so high that make-whole calls are rarely exercised for refinancing.

A sinking fund requires the issuer to retire part of the issue each year, either by calling bonds at par or buying them in the market. It reduces default risk for the issue as a whole but means any individual bond may be redeemed early.

High yield bonds typically use traditional calls with a non-call period followed by a declining premium. Call terms are one of the clearest differences between the two ends of the credit spectrum, and they should be checked on every bond before it is recommended.

Practice Questions to Test Yourself

Question one: Why do callable bonds pay a higher yield than comparable non-callable bonds? Because the issuer holds the option to redeem early, which exposes the investor to call risk and reinvestment risk. The extra yield compensates for those risks.

Question two: Interest rates have fallen sharply. Which bond is most likely to be called? A high-coupon bond whose call protection has ended, because the issuer can refinance at a much lower rate. A low-coupon bond, or one still within its protection period, is unlikely to be called.

Question three: A bond trades at a premium and is callable in four years. Which yield will be lowest? Yield to call, because the premium is lost over fewer years if the bond is redeemed early. Yield to call is therefore also the yield to worst.

Question four: A bond trades at a discount. Rank the coupon rate, current yield, yield to maturity and yield to call from lowest to highest. Coupon rate, current yield, yield to maturity, then yield to call. The discount is gained back faster on an early call, so yield to call is highest.

Question five: A client needs income that will last exactly twenty years to fund a fixed obligation. Which bond is most suitable, all else equal: a callable bond or a non-callable bond with the same credit quality and maturity? The non-callable bond, because it guarantees the term of the income stream, while a callable bond could be redeemed early and leave the client reinvesting at lower rates.

Key Points to Retain

A callable bond lets the issuer redeem early, usually after a call protection period and at a stated call price. A non-callable bond runs to maturity. Callable bonds pay higher yields to compensate investors for call risk and reinvestment risk.

Issuers call when rates fall, so callable bond prices are capped near the call price while non-callable bonds rise freely. For a premium bond, the yield order runs coupon, current yield, yield to maturity, yield to call, and yield to worst is the figure to quote.
