Fixed Income
Build stability into your portfolio.
Fixed income can provide a defined role within a portfolio through income generation, capital stability and diversification. The right instrument, maturity and credit exposure matter as much as the headline yield.
Fixed income investments are subject to interest-rate, credit, liquidity and market risks. The return and repayment of principal may depend on the issuer, instrument and market conditions. Past performance does not guarantee future results. Information presented is for educational purposes and should not be interpreted as a recommendation to buy or sell any particular security.
What role should fixed income play in your portfolio?
Fixed income can serve different purposes for different investors. It may provide income, help manage portfolio volatility, support near- and medium-term liabilities, or diversify exposure to growth assets.
The right fixed-income allocation begins with the portfolio's purpose, not the advertised yield.
More than just interest income.
Fixed-income investments generally involve lending capital to an issuer in exchange for interest/coupon payments and repayment according to the instrument's terms.
Principal
The amount invested.
Coupon / Interest
The contractual or expected income associated with the instrument.
Maturity
When the instrument is scheduled to mature or repay principal.
Yield
The return implied by the price and cash flows of the instrument.
Credit
The issuer's ability and willingness to meet its obligations.
Duration
Sensitivity to changes in interest rates.
Not all fixed income is the same.
This is not an exhaustive product catalogue — it reflects the general categories relevant to fixed-income planning, finalised against what is actually offered.
Who are you lending to?
| Government / Sovereign | Corporate |
|---|---|
| Issuer is government-related | Issuer is a company |
| Generally lower credit risk for sovereign obligations | Credit risk varies by issuer |
| Yield influenced by government borrowing and rates | Yield also reflects credit premium |
| Different liquidity characteristics | Liquidity can vary considerably |
| Risk profile depends on instrument | Requires issuer/credit assessment |
Higher yield can compensate investors for taking additional risk. It should never be viewed in isolation.
Yield is compensation for risk.
When two instruments offer different yields, the difference may reflect differences in credit quality, duration, liquidity, structure or market expectations.
Higher yield does not automatically mean better investment.
What are you lending to?
Issuer Quality
Financial strength and business stability.
Cash Flow
Ability to service obligations.
Leverage
Debt relative to the issuer's financial capacity.
Coverage
Ability to meet interest obligations.
Rating
External credit assessment, where applicable.
Structure
Security, seniority, covenants and other terms.
A credit rating is one input into credit analysis, not a substitute for understanding the instrument.
When rates move, bond prices can move.
This relationship is most relevant to market-valued fixed-income instruments, and the effect varies according to maturity, duration and instrument structure.
How sensitive is the investment to interest rates?
Duration is a way of understanding how sensitive a fixed-income investment or portfolio may be to changes in interest rates.
Match the investment to the time you need the money.
Do not select maturity first. Define the liability first.
Can you exit when you need to?
- Market liquidity
- Bid/ask spreads
- Secondary-market availability
- Lock-ins
- Premature exit conditions
- Issuer-specific liquidity
- Liquidity during stressed markets
An investment can be attractive on paper and still be unsuitable if the liquidity does not match the investor's needs.
The highest yield is not always the best choice.
Yield must be evaluated alongside risk.
Different assets. Different jobs.
| Dimension | Fixed Income | Equities |
|---|---|---|
| Economic exposure | Lending | Ownership |
| Primary return source | Interest / yield + price movement | Earnings growth + valuation |
| Credit risk | Important | Different form of business risk |
| Interest-rate sensitivity | Often significant | Indirect / sector-dependent |
| Capital volatility | Generally lower, but varies | Generally higher |
| Portfolio role | Income / stability / diversification | Growth / ownership |
Fixed income and equities are not substitutes in every portfolio. They often serve different purposes.
Fixed income is broader than fixed deposits.
| Dimension | FD / Bonds / G-Secs / Debt Funds |
|---|---|
| Return structure | Varies by instrument — fixed, market-linked or accrual-based |
| Liquidity | Varies — from lock-in to daily redemption |
| Market value | Some instruments carry mark-to-market movement, others do not |
| Credit exposure | Varies by issuer and instrument |
| Interest-rate exposure | Varies by structure and duration |
| Taxation | Differs by instrument, holding period and structure |
| Maturity | Fixed, flexible, or open-ended depending on instrument |
| Convenience | Varies by access, servicing and platform |
The appropriate instrument depends on the objective and risk profile.
What you earn is not the same as what you keep.
Tax treatment can vary by instrument and may change over time. Investors should evaluate post-tax outcomes rather than headline yields alone.
What happens when the investment matures?
An investment may mature when market yields are lower than when the original allocation was made.
Maturity → Reinvestment Decision → New Rate Environment
Income is not the same as purchasing-power protection.
A fixed return may look attractive in nominal terms while delivering a much smaller real return after inflation.
The objective is not simply to earn a positive return. It is to understand what that return means in real purchasing-power terms.
Fixed income reduces some forms of portfolio risk. It does not eliminate risk.
Credit Risk
Issuer may fail to meet obligations.
Interest-Rate Risk
Market value can change as rates move.
Liquidity Risk
Exit may be difficult or costly.
Duration Risk
Longer duration can increase rate sensitivity.
Reinvestment Risk
Future rates may be lower when capital matures.
Inflation Risk
Returns may not keep pace with rising prices.
Concentration Risk
Too much exposure to one issuer or sector.
Structure Risk
Terms, seniority, security and covenants matter.
Capital stability is not the same as a capital guarantee.
Where does fixed income fit?
Don't let every maturity arrive at once.
- Staggered liquidity
- Reduced reinvestment concentration
- Better matching of liabilities
- Disciplined maturity management
Build cash flows around actual needs.
Fixed income works best when its cash flows are connected to a purpose.
Purpose → Issuer → Credit → Yield → Duration → Liquidity → Tax → Allocation → Review

09 Review
Does it continue to serve its intended purpose?
Every fixed-income allocation needs a reason.
A high coupon is not an investment thesis.
Fixed income has its own investor biases.
Yield Chasing
Choosing the highest advertised yield.
Safety Illusion
Assuming "fixed" means risk-free.
Familiarity Bias
Choosing only familiar issuers.
Recency Bias
Assuming current interest rates will persist.
Anchoring
Focusing on an old interest rate.
Credit Complacency
Assuming ratings eliminate credit risk.
Liquidity Neglect
Ignoring how difficult it may be to exit.
The word "fixed" describes the structure of the income. It does not mean every risk is fixed.
Common fixed-income mistakes.
Stability requires structure.
Fixed income should not be treated as a passive allocation that requires no review.
The objective is not to maximise yield. It is to build an appropriate risk-adjusted fixed-income allocation.
We don't chase yield. We evaluate what sits behind it.
A fixed-income investment should be assessed through its purpose, issuer, credit quality, duration, liquidity, taxation and role within the broader portfolio.
Yield tells you what you may earn. Risk tells you what you are taking to earn it.
Fit depends on objective, not just the appeal of a fixed return.

What is fixed income?
Fixed income generally refers to investments that involve lending capital to an issuer in exchange for interest or coupon payments and repayment of principal according to the instrument's terms.
How does fixed-income investing work?
An investor provides capital to an issuer, who agrees to pay interest over a defined period and repay principal at or before maturity, subject to the terms and risks of the specific instrument.
What are the different types of fixed-income investments?
Common categories include bank deposits, government securities, corporate bonds, debt mutual funds and target-maturity structures, among other regulated instruments, each with different risk and liquidity characteristics.
Are fixed-income investments risk-free?
No. Fixed-income investments carry credit, interest-rate, liquidity, reinvestment, inflation and other risks. Capital stability is not the same as a capital guarantee.
What is credit risk?
Credit risk is the risk that an issuer is unable or unwilling to meet its interest or principal obligations. Higher yields can reflect compensation for higher credit risk.
What is interest-rate risk?
Interest-rate risk refers to the way market values of fixed-income instruments can change as interest rates move, particularly for market-valued instruments.
What is duration?
Duration is a way of understanding how sensitive a fixed-income investment or portfolio may be to changes in interest rates. Longer duration generally implies greater potential price sensitivity.
Why do bond prices fall when interest rates rise?
When new instruments offer higher rates, existing instruments with lower fixed rates generally become less attractive at their original price, which can cause their market value to fall.
What is the difference between yield and coupon?
Coupon refers to the stated interest payment on an instrument, while yield reflects the return implied by its current price and cash flows, which can differ from the coupon.
What is the difference between bonds and fixed deposits?
Bonds and fixed deposits can differ in liquidity, market value behaviour, credit exposure, interest-rate exposure, taxation and convenience. Neither is universally superior — the appropriate instrument depends on the objective.
What is reinvestment risk?
Reinvestment risk is the risk that when an investment matures, prevailing market yields may be lower than when the original investment was made.
What is liquidity risk?
Liquidity risk refers to the possibility that an investment cannot be exited easily, or can only be exited at a cost, particularly during stressed market conditions.
How does inflation affect fixed-income returns?
A fixed nominal return can look attractive on paper while delivering a smaller real return once inflation is accounted for, reducing purchasing-power growth.
How is fixed income taxed?
Tax treatment can vary by instrument, holding period and investor tax slab, and may change over time. Investors should evaluate expected post-tax outcomes rather than headline yields alone.
How much fixed income should an investor hold?
There is no universal allocation. The appropriate amount depends on objectives, liabilities, liquidity needs, existing exposure, risk tolerance and overall portfolio construction.
How does SA Hedge Fund evaluate fixed-income investments?
Through a structured framework covering purpose, issuer, credit quality, yield, duration, liquidity, tax outcome, portfolio allocation and ongoing review.
Build stability with intention.
Fixed income should be selected around your objectives, liquidity needs, risk tolerance and broader portfolio — not simply the highest advertised yield.
