Read the terms before reading the yield
A conventional bond has a face value, a maturity date and a coupon arrangement. Face value is the principal specified by the security; it is not necessarily the price an investor pays in a later market trade. A fixed coupon is based on the stated principal. Other bonds can have floating rates, no periodic coupon or special redemption features.
The issuer might be a government, municipality or company. The label bond does not make these issuers equally creditworthy. Seniority, collateral and contract terms can also change a bondholder’s position. The security’s documents matter as much as the broad asset-class name.
Coupon rate is not the same as purchase yield
Imagine a fictional $1,000 face-value bond with a 4% annual coupon and two years remaining. For simplicity, assume one $40 coupon at the end of each year and $1,000 principal returned with the second coupon. The scheduled cash flows are $40 after one year and $1,040 after two. This example assumes full payment and omits fees and taxes.
Buying at $1,000 makes the annual coupon equal to 4% of the purchase price. Buying the same bond at $950 leaves the contractual $40 coupon unchanged, but $40 ÷ $950 is about 4.21%. That is current yield, not the full yield to maturity. The latter also accounts for timing and the difference between purchase price and principal repayment.
Several risks can operate at once
Credit risk concerns payment. Interest-rate risk concerns how a bond’s market price responds when required yields change. Inflation can reduce the purchasing power of the payments. Liquidity can affect the price available when selling. A callable bond may be redeemed under its contract before the date an investor expected to hold it.
A plan to hold until maturity does not make all those issues disappear. It may reduce concern about interim price changes if the investor can actually hold and receives all promised payments. It does not cure default risk or guarantee the money will buy the same amount of goods later.
An individual bond and a bond fund are different
A bond fund owns a portfolio that can change as securities mature, are sold or are replaced. Its shares do not generally promise to return a particular original investment on the maturity date of one underlying bond. Read the fund’s mandate and duration rather than transferring an individual bond’s repayment story to the entire fund.
In a market report, separate the coupon, the traded price and the quoted yield. A sentence about rising yields often describes a market repricing, not a sudden increase in a fixed coupon already promised to existing holders.
A fixed-coupon bond’s price falls. Does its scheduled coupon automatically rise?
Show the explanation
No. Its contractual coupon stays fixed. A lower purchase price can increase the yield calculated for a new buyer, subject to the payment assumptions and bond terms.
