Topic guide: Bond prices, coupons and market yield

A bond's coupon is a contractual cash flow, while market yield reflects the return implied by price and assumptions. Understanding their distinction helps explain why fixed-coupon bond prices respond to changing required returns.

This is an independent topic guide, not the official syllabus. Compare it with the current paper outline and rules published by the examination authority.

01 / UNDERSTANDING

Learning objectives

Cover fixed cash flows, coupon rate, discounting and market yield. The objective is to explain the price-yield relationship with explicit assumptions and distinguish contractual income from an investor's realised return. Use the same promised cash-flow stream under two assumed required yields and compare its present values. Then distinguish the coupon calculation from the price-based yield concept. The learner should explain why a contractual payment can remain fixed while the market price needed to attract investors changes.

02 / UNDERSTANDING

The concept in context

A plain fixed-coupon bond promises specified cash flows subject to the issuer's ability and obligation to pay. Market participants value those flows using a required return. With other assumptions unchanged, a higher required yield lowers their present value and a lower required yield raises it.

03 / UNDERSTANDING

A worked learning case

A bond pays a fixed coupon and matures at a stated amount. Newly available comparable investments offer a higher required return in a hypothetical scenario. The existing bond's fixed cash flows become less attractive at its old price, so a lower price is needed to provide the higher required yield, assuming other factors remain unchanged.

ORIGINAL EDUCATIONAL PRACTICE

Try it before you check.

With fixed cash flows and other assumptions unchanged, what happens to bond price when required yield rises?

Show the answer and reasoning

Price falls.

The cash flows are discounted at a higher required rate, reducing their present value. The fixed coupon itself does not rise merely because market yields increase. This inverse relationship is a controlled comparison; actual bond prices can also reflect changes in credit risk, liquidity and expected cash-flow performance.

Two traps to watch for.

  • Treating coupon rate and market yield as identical concepts.
  • Applying the inverse relationship without holding other factors constant.

YOUR TOPIC-SPECIFIC LEARNING MAP

Your revision map

  1. List the bond's promised coupon and maturity cash flows.

  2. Explain how a higher discount rate changes their present value.

  3. Separate the fixed coupon from the investor's purchase-price-based return.

Explain the idea, apply it to a new situation, then check what changed in your reasoning.
