This guide explains a topic and a method for reading related news. It does not report a newly announced event. Check the issuing authority for current facts.
01 / UNDERSTANDING
Reading the news
When a report says bond yields rose, check whether it also describes falling market prices. Do not read the yield change as an automatic change in the coupon of an existing fixed-rate bond. Identify the quoted measure and maturity, then separate market valuation from the cash payments promised by the instrument's terms.
02 / UNDERSTANDING
The concept in context
Yield to maturity is a discount rate that equates the price with the promised cash flows under stated conventions. It is not a guarantee of the investor's realised return, which depends on factors such as sale price, payment performance and reinvestment. A precise discussion identifies the purchase price, holding period and cash-flow assumptions.
03 / UNDERSTANDING
A worked learning case
A fictional bond pays an annual coupon of 6 units on a face value of 100. One learner buys it for 100 and another for 90. Both receive the same promised coupon, but their current yields differ. The class then includes the eventual principal repayment to explain why current yield alone does not measure yield to maturity.
ORIGINAL EDUCATIONAL PRACTICE
Try it before you check.
Does buying a fixed-coupon bond at a lower price change its promised coupon amount?
Show the answer and reasoning
No; it changes the relationship between the purchase price and the cash flows.
The contractual coupon follows the bond's terms, not the price paid by a new holder in the market. A lower purchase price raises the coupon relative to that price, all else equal. A complete holding-period return still needs the remaining payments, any sale or redemption value and relevant reinvestment assumptions.
Two traps to watch for.
- Calling the coupon rate the investor's guaranteed realised return.
- Using current yield as if it included every remaining cash flow.
