What Is a Coupon Rate?
A coupon rate is the yield paid by a fixed-income security; a fixed-income security’s coupon rate is simply just the annual coupon payments paid by the issuer relative to the bond’s face or par value. The coupon rate, or coupon payment, is the yield the bond paid on its issue date. This yield changes as the value of the bond changes, thus giving the bond’s yield to maturity. 1:32
How a Coupon Rate Works
A bond’s coupon rate can be calculated by dividing the sum of the security’s annual coupon payments and dividing them by the bond’s par value. For example, a bond issued with a face value of $1,000 that pays a $25 coupon semiannually has a coupon rate of 5%. All else held equal, bonds with higher coupon rates are more desirable for investors than those with lower coupon rates.
The coupon rate is the interest rate paid on a bond by its issuer for the term of the security. The term “coupon” is derived from the historical use of actual coupons for periodic interest payment collections. Once set at the issuance date, a bond’s coupon rate remains unchanged and holders of the bond receive fixed interest payments at a predetermined time-frequency.
- A coupon rate is the yield paid by a fixed-income security.
- When a market ticks up and is more favorable, the coupon holder will yield less than the prevailing market conditions as the bond will not pay more, as its value was determined at issuance.
- The yield to maturity is when a bond is purchased on the secondary market, and is the difference in the bond’s interest payments, which may be higher or lower than the bond’s coupon rate when it was issued.
A bond issuer decides on the coupon rate based on prevalent market interest rates, among others, at the time of the issuance. Market interest rates change over time and as they move higher or lower than a bond’s coupon rate, the value of the bond increases or decreases, respectively.
Special Considerations: Market Rate and Yield to Maturity
Changing market interest rates affect bond investment results. Since a bond’s coupon rate is fixed all through the bond’s maturity, a bondholder is stuck with receiving comparably lower interest payments when the market is offering a higher interest rate. An equally undesirable alternative is selling the bond for less than its face value at a loss. Thus, bonds with higher coupon rates provide a margin of safety against rising market interest rates.
When investors buy a bond initially at face value and then hold the bond to maturity, the interest they earn on the bond is based on the coupon rate set forth at the issuance. For investors acquiring the bond on the secondary market, depending on the prices they pay, the return they earn from the bond’s interest payments may be higher or lower than the bond’s coupon rate. This is the effective return called yield to maturity.
For example, a bond with a par value of $100 but traded at $90 gives the buyer a yield to maturity higher than the coupon rate. Conversely, a bond with a par value of $100 but traded at $110 gives the buyer a yield to maturity lower than the coupon rate.
