Introduction to Investment: Bonds

Study bonds for CISI Introduction to Investment, with a UK-specific reading frame built around the official chapter structure and exam weighting.

Bond questions on this paper are usually practical: who issued the instrument, how does it pay, what risks matter most, and how do yield and price move relative to one another? A solid foundation answer does not need advanced fixed-income mathematics, but it does need proper classification. The most common failure is over-simplification. Candidates often remember that bonds pay interest and redeem at maturity, then lose marks because they miss whether the bond is a gilt, a corporate issue, a floating-rate structure, or an instrument whose main risk is duration, credit, or inflation.

What this chapter is really testing

The exam normally rewards you for reading the characteristics in the stem: issuer type, maturity, coupon structure, seniority, and quality. Once that classification is clear, the likely risk and return profile becomes more defensible.

It also tests the basic relationship between price, yield, and credit quality. You do not need specialist analytics to know that long-dated fixed-rate bonds react differently to rate changes than short-dated or floating-rate structures.

Bond cash-flow classifier

Bond termMeaningExam clue
CouponRegular interest payment stated as a percentage of nominal valueIncome from holding the bond
Nominal or par valueReference amount used for coupon and redemptionOften 100 or 100p in examples
Redemption dateDate principal is due to be repaidMaturity or final repayment
Market pricePrice paid in the secondary marketCan be above or below par
YieldReturn measure linking cash flows to current priceHigher yield may imply lower price or higher risk

Flat-yield formula

Flat yield uses annual coupon income relative to current market price:

\[ \text{Flat yield} = \frac{\text{Annual coupon}}{\text{Market price}} \times 100 \]

If a bond pays an annual coupon of 5 and trades at 95, the flat yield is:

\[ \frac{5}{95} \times 100 = 5.26\% \]

Flat yield is a simple income measure. It does not fully capture redemption gain or loss, reinvestment, or the timing of cash flows. Yield to maturity is broader because it considers both coupon income and the return of principal at maturity.

Section-by-section lesson

Bond terminology and characteristics

Coupon, maturity, redemption value, issuer, yield, and market price are the core language pieces. Most questions become manageable if you can tell whether the bondholder is receiving fixed contractual cash flows or something more variable.

  • If the question is really about contractual income and redemption, start with basic bond terms before trying to compare sectors.
  • Yield language often indicates a relationship question between market price and promised cash flows.

Government bonds

In UK framing, gilts are the main reference point. The exam typically uses them as the lower-credit-risk benchmark rather than as an invitation into specialist sovereign-debt policy detail.

  • When credit quality and sovereign backing are central clues, a gilt-style answer often becomes attractive.
  • Do not assume a government bond automatically eliminates market or inflation risk.

Corporate and specialist bond structures

Corporate and specialist structures add credit and structural complexity. Floating-rate notes, convertibles, subordinated issues, and similar instruments exist because issuers and investors want different balances of risk, income, and optionality.

  • If the stem points to issuer credit or special structural features, move out of plain-gilt thinking.
  • A bond can still be a bond even when it has extra features that change risk and pricing behaviour.

Bond risk, yield, and credit quality

This is where the classification work pays off. Interest-rate risk, credit risk, inflation risk, and yield comparison questions often look hard only when the candidate has not identified the bond type correctly first.

  • Longer-dated fixed-rate bonds usually show more price sensitivity to yield moves than very short or floating-rate issues.
  • Higher yield is often compensation for higher risk, not a free upgrade.

Best study order inside this chapter

  1. Bond terminology and characteristics: Build the vocabulary of cash flows and pricing first.
  2. Government bonds: Use gilts as the reference point for issuer quality.
  3. Corporate and specialist bond structures: Add credit and structural variation next.
  4. Bond risk, yield, and credit quality: Finish with the relationships that decide most exam questions.

What stronger answers usually do

  • identify the issuer and structure before discussing risk
  • separate sovereign-credit strength from interest-rate sensitivity
  • treat yield as a pricing and risk clue, not simply as a reward number
  • remember that a higher coupon or yield does not remove duration or credit concerns
  • calculate simple yield only after confirming which cash flow and price the question supplies
  • distinguish coupon income, price movement, redemption outcome, and credit-quality change

Sample Exam Question

An investor expects UK market yields to fall and wants a bond holding most likely to benefit from that move if credit quality is unchanged. Which is the best fit?

  • A. A long-dated fixed-rate gilt
  • B. A floating-rate note resetting every quarter
  • C. A notice deposit account
  • D. A short-term money-market placement

Answer: A.

If yields fall, the price of an existing long-dated fixed-rate bond tends to benefit more than shorter-dated or floating-rate instruments, assuming no offsetting credit event. That is the key interest-rate-sensitivity distinction.

Common traps

  • assuming government backing removes all bond risk
  • choosing the highest-yielding answer without asking why the yield is higher
  • forgetting that floating-rate structures behave differently from long fixed-rate bonds when rates move
  • using cash products when the question is specifically about bond pricing sensitivity

Key takeaways

  • Bond questions are usually solved by classification first: issuer, structure, and maturity.
  • Gilts are the UK sovereign reference point, but they still carry market risk.
  • Price, yield, and credit quality belong together in the same decision.
