Coupon yield is a fundamental concept in the fixed-income market. It refers to the annual interest income earned by a bondholder as a percentage of the bond’s face value. Unlike discount yield, which calculates yield based on the bond’s current market price and any price discount, coupon yield is tied directly to the bond’s face value and the periodic interest payments known as coupons.
Historical Context
Bonds have been used as a method of raising capital for centuries. Historically, governments and corporations issue bonds to finance projects and operations. The practice dates back to at least the 17th century. The concept of coupon yield became prominent as bond markets developed, providing investors with a way to measure their annual income from bond investments.
Types of Coupon Yield
- Fixed Coupon Yield: This is the most common type where the bond pays a fixed percentage of interest annually.
- Floating Coupon Yield: The coupon rate varies based on a benchmark interest rate, such as LIBOR or the prime rate.
- Zero-Coupon Bonds: These bonds do not pay periodic coupons and instead are issued at a discount, making the yield calculation different.
Key Events
- Introduction of Government Bonds: In the late 17th century, governments started issuing bonds, formalizing the concept of coupon payments.
- Development of Corporate Bonds: The late 19th and early 20th centuries saw corporations issuing bonds, further refining yield calculations.
Detailed Explanation

The coupon yield is calculated using the formula:
For instance, if a bond with a face value of $1,000 pays an annual coupon of $50, the coupon yield is:

Importance and Applicability
Understanding coupon yield is crucial for:
- Investors: It helps in assessing the income generated from bond investments.
- Financial Analysts: They use it to compare the income potential of different bonds.
- Portfolio Managers: Coupon yield informs decisions about bond selections in investment portfolios.
Examples
- Fixed Coupon Bond: A bond with a face value of $1,000 and a 6% coupon rate pays $60 annually, yielding 6%.
- Floating Coupon Bond: A bond whose coupon rate is linked to LIBOR. If LIBOR is 3%, and the bond’s margin is 2%, the coupon rate for that period would be 5%.
Considerations
- Interest Rate Risk: As market interest rates change, the market price of a bond and thus its effective yield to a new investor can change.
- Credit Risk: The risk of issuer default impacts the perceived value of the coupon yield.
Related Terms
- Yield to Maturity (YTM): The total return anticipated if the bond is held until it matures.
- Current Yield: The bond’s annual coupon payments divided by its market price.
- Discount Yield: A yield calculation method used for zero-coupon bonds.
Comparisons
- Coupon Yield vs. Yield to Maturity: Coupon yield focuses only on interest income, while YTM includes all income and capital gains/losses.
- Coupon Yield vs. Current Yield: Coupon yield uses the face value in calculations, while current yield uses the current market price.
