Bond Basics

What is a debt security in plain language?

It is an instrument through which an issuer borrows money from investors and promises repayment under stated terms.

What is the difference between money market and longer debt?

Debt maturing within a year is treated as money market debt. Longer paper behaves more like normal bond exposure.

Why should investors care?

Because maturity profile changes liquidity, rate sensitivity, and how the security may behave in a fund.

What is yield in simple terms?

It is the return an investor earns or expects to earn from a debt security.

What can that return include?

Yield can come from interest income and capital gain depending on price movement.

Why is yield not the whole story?

Because the same yield can come with very different credit risk and interest-rate sensitivity.

What is fixed-rate debt?

It pays a fixed interest rate for the agreed period.

What is floating-rate debt?

It pays interest linked to a market reference rate, so the interest can change over time.

Why does floating-rate debt behave differently?

Because its coupon adjusts with the market, so its value can remain steadier in some rate environments.

What happens when market yields rise?

Older fixed-rate bonds become less attractive, so their market value tends to fall.

What happens when market yields fall?

Older fixed-rate bonds can gain value because their fixed coupon looks more attractive than new alternatives.

What is the one line rule?

Bond prices and yields usually move in opposite directions.

Why do non-government bonds usually offer higher yield?

Because investors need compensation for default risk that does not exist in the same way with government securities.

What is yield spread?

It is the extra yield offered by a non-government security over a comparable government security.

What does a higher spread often signal?

Higher perceived credit risk.

Why are longer-tenor debt securities more sensitive?

Because longer maturity usually means bigger price response when market yields change.

What is the simplified idea behind duration?

It is a way to think about how sensitive a bond is to interest-rate movement.

What should a beginner remember without getting technical?

Longer maturity and higher duration usually mean higher interest-rate sensitivity.

What should you check first in bond-style exposure?

Look at yield, issuer quality, maturity, and whether the rate is fixed or floating.

What is the common beginner mistake?

Reading higher yield as free return instead of asking what extra risk is being priced in.

What is the final rule?

In bonds, return, safety, and sensitivity move together. Read all three before investing.
