A bond is one of the most fundamental financial instruments in the global markets. It plays a vital role in funding governments, corporations, and major institutions. Bonds are so central to modern finance that they influence interest rates, investment strategies, and even the global economy. In fact, some bonds like Eurobonds trade across international markets, showing how wide and interconnected fixed-income markets have become.
This glossary article explains what a bond is, how it works, the main types of bonds, why they matter, their risks, and how traders and investors use them.
What Is a Bond?
A bond is a type of fixed-income security that represents a loan made by an investor to a borrower. The borrower can be a government, municipality, or corporation. In return for the loan, the borrower promises to:
- Pay back the principal (face value) at maturity.
- Make periodic interest payments (called coupon payments) at a predetermined rate.
In simple terms, a bond works like an IOU. Investors lend money to the issuer, and the issuer promises to repay on set dates.
Bonds are essential because they provide stable income, diversify portfolios, and help companies and governments fund long-term projects.
How Bonds Work
Bonds operate through a straightforward structure, but their pricing and trading can become complex. Here’s how they function:
1. Issuance
The issuer creates the bond and sells it to investors. The bond includes terms such as:
- Face value (par value)
- Coupon rate
- Maturity date
- Payment schedule
2. Coupon Payments
Most bonds pay interest semi-annually or annually. For example:
- A $1,000 bond with a 5% coupon pays $50 per year.
3. Maturity
On the maturity date, the issuer returns the face value to the investor. If a bond matures in 10 years, the investor receives interest for 10 years and then gets the principal back.
4. Secondary Market Trading
After issuance, most bonds are traded on the secondary market. Their prices fluctuate due to:
- Interest rate changes
- Credit ratings
- Market demand
Bond prices move inversely to interest rates:
When interest rates rise, bond prices fall.
When rates fall, bond prices rise.
This is one of the most important principles in fixed-income investing.
Why Bonds Are Important
Bonds have major functions across the economy:
1. Funding Governments and Projects
Governments use bonds to fund national budgets, infrastructure, and social programs.
2. Corporate Financing
Businesses issue bonds to expand operations, acquire assets, or refinance debt.
3. Stabilizing Portfolios
Investors rely on bonds for:
- Steady income
- Lower volatility
- Hedging stock market risks
4. Benchmarking Interest Rates
Government bonds (especially U.S. Treasuries) serve as benchmarks for global lending rates.
5. Global Economic Impact
Bond yields affect mortgage rates, business loans, currency markets, and even equity valuations.
Key Components of a Bond
Understanding bond structure helps investors evaluate returns and risks.
1. Face Value (Par Value)
The amount repaid at maturity is usually $1,000 for corporate bonds.
2. Coupon Rate
The fixed interest rate paid to investors.
3. Coupon Payment
The actual cash paid, calculated as:
Coupon Rate × Face Value
4. Maturity Date
The date the principal is repaid.
5. Yield
Yield measures return. There are several types:
- Current yield
- Yield to maturity (YTM)
- Yield to call (YTC)
YTM is the most used because it accounts for:
- Interest payments
- Price changes
- Time to maturity
6. Credit Rating
Agencies like Moody’s, S&P, and Fitch score the issuer’s creditworthiness.
Higher ratings = lower risk but lower returns.
Lower ratings = higher risk but higher returns.
Types of Bonds
Bonds come in many forms, each serving different financial needs.
1. Government Bonds
Treasury Bonds (T-Bonds)
Issued by national governments and considered low-risk.
Examples include:
- U.S. Treasury Bonds
- UK Gilts
- Kenyan Treasury Bonds
- Japanese Government Bonds (JGBs)
Municipal Bonds (Munis)
Issued by cities, counties, or states. Often tax-free.
2. Corporate Bonds
Issued by companies to raise funds. Two major types:
Investment-Grade Bonds
Lower risk, stable returns.
High-Yield (Junk) Bonds
Higher risk, higher potential returns. Issued by companies with lower credit ratings.
3. International Bonds
These include foreign-issued bonds sold outside the issuer’s home country.
Eurobond
A Eurobond is a bond issued in a currency different from the currency of the country where it is issued.
Example:
A Kenyan company issuing a bond denominated in U.S. dollars in the European market.
Eurobonds help issuers access international investors and often have lower borrowing costs.
4. Zero-Coupon Bonds
These bonds do not pay periodic interest. Instead, they are sold at a deep discount and mature at par value.
The investor’s profit is the difference between the purchase price and par value.
Example:
A zero-coupon bond sold at $600 and redeemed at $1,000 earns $400 at maturity.
5. Convertible Bonds
These bonds allow investors to convert bond holdings into a company’s shares at a specific conversion rate.
They offer:
- Lower coupon rates
- Upside potential from stock price appreciation
6. Callable and Puttable Bonds
Callable Bonds
The issuer can repay the bond early.
Benefit to issuer, risk to investor.
Puttable Bonds
The bondholder can demand early repayment.
Benefit to investor, cost to issuer.
How Bonds Are Priced
Bond pricing depends heavily on interest rates and market conditions.
Interest Rate Relationship
Bond prices move in the opposite direction from interest rates.
- When interest rates rise → existing bonds become less attractive, → prices fall.
- When interest rates fall → existing bonds become more attractive, → prices rise.
Discount, Par, and Premium
A bond trades:
- At par when price = face value
- At a discount when price < face value
- At a premium when price > face value
Advantages of Bonds
1. Predictable Income
Fixed interest payments create a stable cash flow.
2. Lower Risk
Bonds are generally less volatile than stocks.
3. Diversification
They reduce overall portfolio risk.
4. Protection During Market Downturns
Investors shift to bonds when stock markets crash.
5. Priority in Bankruptcy
Bondholders are paid before shareholders.
Limitations and Risks of Bonds
1. Interest Rate Risk
When rates rise, bond prices fall.
2. Inflation Risk
Inflation reduces real returns.
3. Credit Risk
Issuers may default, especially with junk bonds.
4. Liquidity Risk
Some bonds may be hard to sell quickly.
5. Currency Risk
International bonds expose investors to exchange rate fluctuations.
Bonds in Trading and Investing
Bonds serve different purposes across financial markets.
1. Income Generation
Retirees and conservative investors rely heavily on bonds for consistent returns.
2. Portfolio Hedging
Bonds often move opposite to stocks, helping to offset equity volatility.
3. Yield Trading
Traders speculate on movements in interest rates by buying or selling bonds.

Bond yields influence currency markets, commodity prices, and stock indexes.
5. Corporate Finance
Companies strategically issue bonds to manage funding costs.
Examples of Bonds
Example 1: Government Bond
The government issues a 10-year bond at a 6% coupon rate.
An investor earns 6% annually and receives principal at maturity.
Example 2: Corporate Bond
A company issues a 5-year bond with an 8% coupon.
Investors expect higher returns due to higher risk.
Example 3: Eurobond
The Nigerian government issues a U.S.-dollar-denominated bond in Europe.
Investors worldwide can buy it without local currency restrictions.
Example 4: Zero-Coupon Bond
A bond is sold at $500 with a maturity value of $1,000.
The investor earns $500 at maturity.
