What are bonds? A Complete Guide to Understanding Bond Investing in 5 Minutes

You must have heard the word “bond”, but what exactly is it?

Many people are familiar with stocks, funds, real estate, but are unfamiliar with bonds. In fact, bonds are one of the largest asset classes on the global financial market, with the conglomerate Buffett holding a large amount of U.S. debt for a long time.

This article will tell you in the simplest way: what bonds are, how they work, what are the risks, and who they are suitable for investing. After looking, you will understand why bonds are called “fixed income”.

1. What is a bond? Make it clear in one word

A bond is a “loan” where you lend money to a government or company and the other party promises to pay you interest on a regular basis and repay the principal at maturity.

To give an example:

• Government issues a “10-year bond” worth $10 million at an annual interest rate of 3%
• You bought this bond, which is equivalent to borrowing $10,000 to the government.
• For the next 10 years, the government will pay you $3,000 a year in interest
• Ten years later, the government will pay you $10,000 in principal.

This is the most basic way bonds work.

The Three Core Elements of Bonds

① Face amount (principal)The amount you borrowed, for example $10 million. The full amount will be refunded to you when it expires.

② Box Office RateA fixed rate of interest paid to you each year, such as an annual interest rate of 3%.

③ Expiration DateThe term of the loan can be 1 year, 5 years, 10 years, 30 years, etc. Repayment of principal upon maturity.

💡 Simple to understand: Bonds are like if you deposited money in a bank, but the target is not a bank, but a government or a corporation. Fixed interest, maturity repayment, is therefore known as a “fixed income” investment.

Second, what are the types of bonds?

Bonds differ from issuer to issuer and are mainly divided into the following:

① Government Debt (National Debt)

Issued by the national government to raise funds for national construction, military fees, etc.

Features:

• Minimal risk (unless state bankruptcy)
• Lower interest rate (usually 1~ 3%)
• Good liquidity, easy to buy and sell

Common examples:

• U.S. Treasury
• Taiwan Debt
• Japanese Debt (JGB)

② Corporate Debt (Corporate Debt)

Issued by enterprises to raise working capital, expand business, etc.

Features:

• Medium risk (depending on company body)
• Higher interest rate (usually 3~ 8%)
• Need to evaluate the company's credit rating

Common examples:

• TSMC Corporate Debt
• Apple Corporate Debt
• China Telecom Corporation Debt

③ Municipal Debt (Local Government Debt)

Issued by the local government or public sector for infrastructure.

Features:

• Risk Between Debt and Corporate Debt
• Moderate interest rate (usually 2~ 4%)
• Less common in Taiwan, very common in the United States

④ High Yield Bonds (Junk Bonds)

Issued by companies with a lower credit rating, the risk is high but the interest rate is also high.

Features:

• High risk (company may close)
• High interest rate (usually 8~ 15%)
• Suitable for high risk takers

⚠️ Key Reminder: The risk and reward of bonds are proportional. Government bonds are the safest but have low interest rates; high yield bonds have high yields but may be bloodless.

3. How to make money on bonds? Two ways to make money

There are two ways to make money on investment bonds:

Method One: Earn Interest (Holding Expiration)

This is the most basic way. YOU BUY BONDS, HOLD MATURITIES, CHARGE A FIXED INTEREST EACH YEAR, AND GET THE PRINCIPAL BACK AT MATURITY.

Example:

• You bought $100 million in 5-year bonds with an annual interest rate of 2%
• Earn $2 million in interest per year
• Receive $100 million in principal after 5 years
• Earn a total of $10 million in interest

This method is stable, but the payoff is not high.

Method 2: Earn the spread (mid-way sell)

Bonds can be bought and sold in the market and the price fluctuates as market interest rates change.

Core Logic:

• Market interest rates fall → Bond prices rise
• Market interest rates rise → bond prices fall

Example:

• You bought a debt worth $100 million at an annual interest rate of 3%.
• Later, the market interest rate fell to 2%
• Your 3% bond has become a hit and the price rises to $105 million
• You sell and make a difference of 5 million

This method pays off more, but requires determining the rate movement.

Fourth, what are the risks of bonds?

Although bonds are called “fixed income”, it does not mean that there is absolutely no risk:

Risk 1: Risk of default

Issuers may not have made money yet, especially corporate debt. The company closes, and the bonds become scrap paper.

How to reduce: Choose bonds with a high credit rating (AAA, AA)

Risk 2: Interest Rate Risk

When market interest rates rise, the price of old bonds falls. If you want to sell halfway, you may lose.

How to reduce: Hold maturity is not affected by price fluctuations

Risk 3: Expansion risk

If the inflation rate is higher than the bond rate, your purchasing power will decrease. For example, an interest rate of 2% but inflation of 3% is actually a loss.

How to reduce: Choose “Anti-Inflation Bonds” (TIPS) or High Interest Rate Bonds

Risk 4: Liquidity risk

Some bonds are not easy to sell, especially small company bonds or long-term bonds.

How to reduce: Choose to trade large bonds or large corporate bonds

5. Who are bonds suitable for?

Depending on your investment objectives and risk tolerance, you can refer to the following judgments:

Perfect for investing in bonds if you...

• Want a stable income and don't want high rewards
• Pursuit of low risk, insurance-oriented
• Approaching retirement age and need cash flow
• Want to balance high-risk assets such as stocks

Not suitable for investing in bonds if you...

• Young and high risk tolerance
• Seek high returns without flinching
• Small amount of funds (bond thresholds are usually higher)
• Want to build wealth fast

💡 Classic configuration rules: “60/40” or “80/20” — 60% stocks + 40% bonds, or 80% stocks + 20% bonds. The older the age, the higher the bond ratio.

6. How do beginners invest in bonds? Three ways

Method 1: Buy Bonds Directly

Buy individual bonds through a bank or broker, such as a TSMC corporate bond.

Advantages: Explicit income, fixed interest at maturityDisadvantages: HIGH THRESHOLD (USUALLY 10,000 JUMPS), POOR LIQUIDITY

Suitable for: Those who have sufficient funds and seek stable cash flow

Method 2: Buy Bond-Based ETFs

Hold a basket of bonds at a time through an ETF, such as:

• 00679B (USD 20-year bond): Track US 20-year bonds
• 00772B (CITIC HIGH RATED CORPORATE DEBT): Investing in highly rated corporate debt

Advantages: Low threshold (can be bought for several thousand dollars), good liquidity, automatic risk dispersionDisadvantages: There are management fees and prices will fluctuate

Suitable for: Ordinary investors who have little capital but want to invest in bonds

Method 3: Buy Bond-Based Funds

Operate on behalf of the fund manager to select the appropriate bond portfolio.

Advantages: Professional management without doing your own researchDisadvantages: High management fees, performance is not always good

Suitable for: People who do not want to study at all, want to be replaced

💡 Beginner Suggestions: Starting with a bond-based ETF, the threshold is low, easy to operate, and the risk is dispersed.

7. Comparison of bonds vs other investment instruments

Positioning Bonds: Balance and Stability

The role of bonds is not to “make you rich fast”, but to “stabilize your portfolio”.

• Bonds are generally relatively stable when stocks fall
• Provides fixed cash flow for retirement planning
• Reduce the volatility of the overall asset portfolio

But for young investors looking to accumulate wealth, the returns on bonds may be too low and not stimulating enough.

8. Do young people need to invest in bonds?

This is a question for a lot of newbies. The answer is:Do not rush, but know.

Why are young people not in a hurry to invest in bonds?

① Time is the greatest asset

Young people are 30 to 40 years away from retirement and can tolerate short-term fluctuations and should put their money into higher-paying assets (stocks, cryptocurrencies). Bond yields are too low to effectively accumulate wealth.

② Low cash requirements

Young people are often still working, have a stable income and do not need the fixed interest provided by bonds as a living expense.

③ High risk tolerance

Young people, even if they lose, have time to earn back. Use this advantage to invest in high-growth assets.

But why do you need to know about bonds?

① Will definitely be used in the future

As you get older and closer to retirement, bonds become more and more important. Understand now that the future will not be messy.

② Key puzzles for asset allocation

When you have accumulated a certain amount of wealth (for example, more than 200 million), bonds are needed to balance the risks. It's not a bad thing to know too early.

③ Understand the logic of market operations

The relationship between bond prices and interest rates, and how central government policy affects markets, is helpful for all investments.

9. The three bond cold facts you must know

Cold knowledge 1: Bond prices and interest rates “reverse”

Central Bank Rises → Bond Prices Fall Central Bank Decreases Rates → Bond Prices Rise

This is because new bonds have higher interest rates and old bonds are worthless.

COLD KNOWLEDGE 2: BUFFETT IS OVERLY FOND OF U.S. BONDS

Buffett's Foxx company holds a large amount of short-term U.S. debt because it is “safe, liquid, and available at any time.”

Cold knowledge 3: Crooked interest rates are recession warning

“Crooked interest rates” refers to a higher interest rate on short-term bonds than long-term bonds, which usually means that the market expects an imminent recession. This phenomenon has occurred many times in history before economic downturns.

summed

BONDS ARE A “LEND MONEY TO GOVERNMENTS OR COMPANIES AND CHARGE FIXED INTEREST” INVESTMENT VEHICLES WITH LOW RISK, STABLE RETURNS AND ARE SUITABLE FOR CONSERVATIVE INVESTORS OR RETIREES.

Core Values of Bonds:

• Provide fixed cash flow
• Balancing Portfolio Risks
• Safe havens in times of market turbulence

But for young investors:

• Pay is too low and you can't accumulate wealth quickly
• Prioritize high-growth assets such as stocks or cryptocurrencies
• After 40 years of age, join bonds to balance risks

There is no standard answer to investing. The key is to choose tools that fit your age, risk tolerance, and financial goals. Bonds are not bad, just “not the time” for young people.
