Bonds and Fixed Income Products – Understanding the Basics
Helping investors build wealth through disciplined investing, goal-based investing and long-term strategies.
Bonds and fixed-income instruments represent lending arrangements between investors and issuers. This article explains coupon rates, maturity, credit ratings, yields, interest-rate risk, liquidity risk, default risk, and the key characteristics of fixed-income securities.
Fixed-income products form an important part of the financial markets.
Unlike equity securities, where investors acquire ownership interests in companies, bonds generally represent a lending relationship.
When an investor purchases a bond, money is effectively provided to the issuer under specified terms. In return, the issuer may pay interest and repay the principal according to the terms of the security.
What Is a Bond?
A bond is a debt instrument issued by an entity seeking to raise funds.
Issuers can include:
- Central government
- State governments
- Public-sector organisations
- Corporations
- Financial institutions
- Other eligible entities
The bond document defines important terms including:
- Face value
- Coupon rate
- Maturity date
- Payment frequency
- Security structure
- Credit rating
- Redemption terms
Face Value
The face value is the nominal value assigned to a bond.
It is usually the amount on which coupon payments are calculated and may also represent the amount repayable at maturity, subject to the bond terms.
Coupon Rate
The coupon rate represents the interest rate specified by the bond issuer.
For example, if a bond has:
- Face value: ₹1,00,000
- Coupon rate: 8% per annum
the annual coupon may be ₹8,000, subject to the terms of the instrument.
However, the coupon rate is not the same as the investor's actual yield when a bond is purchased at a market price different from its face value.
Maturity Date
The maturity date is the date on which the issuer is expected to repay the principal according to the terms of the bond.
Bonds can have varying maturities, including:
- Short-term
- Medium-term
- Long-term
Some instruments may contain special redemption, call, put, or extension provisions.
What Is Yield?
Yield represents the return measure associated with the bond's market price, coupon payments, and maturity value.
Because bond prices can trade above or below face value, the yield can differ from the stated coupon rate.
For example, when an existing bond's market price falls, its yield may rise, assuming other factors remain unchanged.
Likewise, when the bond price increases, its yield may decline.
Bond Prices and Interest Rates
Bond prices and market interest rates often have an inverse relationship.
When prevailing interest rates increase, existing bonds carrying lower coupon rates may become comparatively less attractive, which can place downward pressure on their market prices.
When interest rates decline, existing bonds with higher coupons may become more attractive, potentially affecting their market values.
This relationship creates interest-rate risk.
Credit Risk
Credit risk refers to the possibility that an issuer may experience difficulty in meeting its payment obligations.
This can affect:
- Interest payments
- Principal repayment
- Market price
- Liquidity
Different issuers have different financial strength and repayment capacity.
Credit Ratings
Credit-rating agencies assign ratings to certain debt instruments based on their assessment of creditworthiness.
Ratings provide an opinion regarding credit risk at a particular point in time.
They are not guarantees of repayment, and ratings can be upgraded or downgraded.
Investors may encounter rating categories such as:
- AAA
- AA
- A
- BBB
- Lower rating categories
The exact meaning depends on the rating agency's published scale.
Liquidity Risk
Not all bonds trade frequently in the secondary market.
An investor seeking to sell a bond before maturity may find:
- Limited buyers
- Wider bid-ask spreads
- Lower market prices
- Delays in executing the transaction
This is generally referred to as liquidity risk.
Default Risk
Default risk refers to the possibility that an issuer may fail to make interest or principal payments according to the contractual terms.
Default risk varies significantly between issuers and securities.
Government-backed securities and corporate debt instruments can have very different risk characteristics.
Secured and Unsecured Bonds
Some bonds are backed by specified assets of the issuer and may be classified as secured instruments.
Others may not have specific collateral and are classified as unsecured.
Security does not eliminate risk, but it can affect the rights and recovery process applicable to bondholders.
Convertible and Non-Convertible Instruments
Some debt instruments may allow conversion into equity shares under specified conditions.
These are generally known as convertible instruments.
Non-convertible debentures, commonly called NCDs, do not convert into equity and continue as debt instruments according to their terms.
Government Securities
Government securities are debt instruments issued by central or state governments.
These may include:
- Treasury bills
- Government dated securities
- State Development Loans
Although sovereign securities generally differ from corporate debt in terms of credit characteristics, their market values can still fluctuate because of interest-rate movements and liquidity conditions.
Corporate Bonds
Corporate bonds are issued by companies to raise capital.
Terms may vary widely between issuers.
Relevant characteristics may include:
- Coupon rate
- Credit rating
- Security
- Maturity
- Seniority
- Liquidity
- Repayment structure
Fixed Deposits and Fixed Income
Fixed deposits are commonly associated with fixed-income products, but they differ structurally from market-traded bonds.
Bank deposits, company deposits, bonds, debt mutual funds, and government securities can all have different:
- Regulatory structures
- Liquidity conditions
- Risk characteristics
- Tax treatment
- Return mechanisms
Therefore, the term “fixed income” covers multiple types of financial instruments rather than a single product.
Taxation of Fixed-Income Products
Tax treatment can depend on:
- Type of instrument
- Interest income
- Capital gains
- Holding period
- Investor category
- Applicable tax law
Tax rules can change, so product taxation needs to be considered based on prevailing regulations.
Important Information Available in Bond Documents
Before participating in a bond issue or transaction, relevant documents may contain information concerning:
- Issuer profile
- Purpose of issue
- Credit rating
- Interest payment terms
- Maturity date
- Security or collateral
- Redemption conditions
- Risk factors
- Default provisions
- Listing details
- Liquidity
- Tax considerations
These disclosures help explain the structure and risks of the instrument.
Bonds Are Not Risk-Free
The word “fixed” in fixed income does not mean that all aspects of the investment are guaranteed or free from risk.
Depending on the instrument, risks can include:
- Credit risk
- Interest-rate risk
- Liquidity risk
- Reinvestment risk
- Inflation risk
- Default risk
- Market-price risk
The relative importance of each risk depends on the individual security.
Conclusion
Bonds and fixed-income instruments provide a mechanism through which governments, companies, and other entities raise debt capital.
Understanding the issuer, coupon, maturity, credit characteristics, liquidity, market price, yield, and repayment terms helps explain how these products operate.
Each fixed-income instrument has its own contractual terms and associated risks, making the official product documentation an important source of information.
