Bonds are a way for governments and companies to raise money by borrowing from investors. When you purchase a bond, you lend them money in exchange for regular interest payments. Once the bond reaches its end date (this is called maturity), you get back the amount initially paid. Bonds come in different forms, each with its own purpose and features. 

‍

Key Takeaways

  • What Bonds Are: Bonds are essentially loans you make to a corporation or government. In return, you receive regular interest payments and get your initial investment back when the bond "matures" or reaches its end date.
  • Main Types of Bonds: The most common types are Corporate Bonds (issued by companies, higher risk/reward), Municipal Bonds (from local governments, often with tax benefits), and Treasury Bonds (from the U.S. government, considered very safe).
  • Why People Invest in Bonds: Bonds are primarily used to generate a steady income stream, preserve capital, and add stability to an investment portfolio to balance out riskier assets like stocks.
  • Key Risks to Consider: The main risks include interest rate risk (if market rates rise, the value of existing bonds may fall), credit risk (the issuer could fail to pay you back), and inflation risk (your fixed payments may not keep up with the rising cost of living).
  • How to Buy Bonds: You can invest by purchasing individual bonds directly through a brokerage, buying U.S. Treasuries on TreasuryDirect, or for simpler diversification, by investing in bond mutual funds or ETFs.

How Do Bonds Work?

When a government or company needs to raise money, it issues bonds. By buying a bond, you are lending them that money. In return, you get paid interest, called a coupon, at regular intervals. Once the bond reaches its maturity date, you get your original amount, called the principal, back. Most bonds are issued at a standard price of $1,000 each. After that, they can be bought and sold on the secondary market. At this point, prices may rise or fall depending on interest rates and demand.

Different Types of Bonds

There are several kinds of bonds, each serving a different purpose. Some are issued by businesses, others by local or federal governments. Knowing which is which and how they differ helps you decide which bonds might best align with your investment goals. 

Corporate Bonds

Corporate bonds are issued by companies looking to raise money for things like product development or expansion. These bonds typically offer higher interest rates than government bonds. However, they also come with more risk. Companies are rated based on their credit quality. Higher-rated ones are considered safer, while lower-rated ones, called high-yield or junk bonds, are riskier but offer bigger returns.

Municipal Bonds

Municipal bonds are issued by state and local governments. One of their main benefits is tax savings. Many are exempt from federal income tax, and sometimes states and local taxes too, if you live in the same state. There are two main types: general obligation bonds, backed by the issuer’s credit, and revenue bonds. These are repaid through specific sources like tolls or utility payments. 

Also, while many municipal bonds offer tax-exempt interest, the IRS provides guidance on which types may still be subject to federal tax depending on the circumstances.

Treasury Bonds

Treasury bonds are long-term bonds issued by the U.S. Government. They’re considered very safe because they’re backed by the government. These bonds pay interest every six months and have longer maturity terms, often 10 to 30 years. Because of the low risk, they tend to offer lower returns but are a stable option for conservative investors.

Government Bonds (Beyond Treasuries)

Other than Treasury bonds, there are other government-backed options as well. These include savings and government agency bonds issued by organizations like Fannie Mae or Freddie Mac. You’ll also find international government bonds, known as sovereign bonds. These are riskier due to currency changes or political shifts in other countries.

Type of Bond Issuer Key Features Risk Level Tax Benefits Ideal For
Corporate Bonds Private companies Higher interest rates; rated by credit agencies; includes investment-grade and high-yield (junk) Moderate to high (varies by rating) None Investors seeking higher returns and willing to take on credit risk
Municipal Bonds State and local governments May offer tax-exempt interest; includes general obligation and revenue bonds Low to moderate Often exempt from federal (and sometimes state/local) taxes Tax-conscious investors, especially those in higher tax brackets
Treasury Bonds U.S. Federal Government Very safe; long-term maturity (10–30 years); fixed semiannual interest payments Very low Interest is exempt from state and local taxes Conservative investors looking for stability and guaranteed returns
Government Bonds (Other) U.S. agencies & foreign governments Includes savings bonds, agency bonds (i.e. Fannie Mae), and sovereign bonds; risk varies Varies (very low to high) U.S. agency bonds may have some tax advantages; international bonds may not Investors seeking exposure to government-backed or international debt instruments

Key Features of Bonds

Before investing in bonds, you should familiarize yourself with important terms that define how they work. These features impact how much you earn and when you get paid. 

Face Value and Maturity

The face value of a bond, also called par value, is the amount the issuer agrees to pay when the bond matures. For most bonds, this is $1,000. Maturity is the length of time until that repayment date. Some bonds mature in just a year or two. Others can take 10, 20, or even 30 years. Knowing the maturity lets you plan when you’ll get your money back. 

Interest Rates and Yields

Bonds pay interest at either a fixed or variable rate. A fixed rate stays the same, while a variable one changes over time. The income you earn from a bond is called the yield. Two common terms are current yield (what you earn based on the bond’s current price) and yield to maturity (your total return if you hold it until it matures). Interest rates also affect bond prices. When rates rise, bond prices generally fall, and vice versa.

Credit Ratings and Risk

Bond issuers are rated by credit agencies based on how likely they are to repay their debt. Ratings range from high-quality (low risk) to low-quality (high risk). Higher-rated bonds typically pay lower interest because they’re safer. Lower-rated bonds offer more income but carry a bigger change of default. Understanding these ratings helps you choose bonds that match your risk tolerance.

Quick Glossary of Bond Terminology

Face Value: The amount of money a bond will repay to the investor at maturity. Most bonds have a face value of $1,000.

Maturity: The date when the bond issuer repays the face value to the investor. Bonds can have short-term or long-term maturities.

Fixed Rate: An interest rate that stays the same for the life of the bond. You receive the same payment amount on a regular schedule.

Variable Rate: An interest rate that can change over time, usually based on a benchmark like the prime rate or inflation index.

Yield: The income you earn from a bond, usually expressed as a percentage of its price. It includes interest payments and potential gains or losses from buying at a discount or premium.

Current Yield: A simple way to measure bond income: annual interest payment divided by the bond’s current market price.

Yield to Maturity (YTM): The total return you’ll earn if you hold the bond until it matures, including all interest payments and any difference between the purchase price and face value.

High-Quality (Low Risk): Bonds from issuers with strong credit ratings. These bonds are more likely to pay on time and offer lower yields.

Low-Quality (High Risk): Bonds from issuers with weaker credit ratings. These carry more risk of default but typically offer higher yields as compensation.

Why Do People Invest in Bonds?

Many people add bonds to their portfolios because they offer a dependable source of income and help balance out more unpredictable investments like stocks. Bonds are often used in retirement planning and are a common way to work toward long-term financial planning. 

They’re known for providing steady interest payments and preserving your invested money. Bonds are practical for those who want to limit risk or create a more balanced mix of investments. They’re also a good fit for investors who prefer regular income over potential high returns.

Bonds vs. Other Investment Vehicles

Bonds aren’t the only way to invest your money. Depending on your goals, you might also consider stocks, mutual funds, or EFTs (Exchange-Traded Fund). Here’s how bonds compare to a few of those options.

Bonds vs. Stocks

Bonds and stocks are two very different types of investments. When you purchase a bond, you’re lending money. When you buy a stock, you’re buying a piece of a company. Stocks offer higher returns, but they also carry more risk. Bonds are typically more stable and provide steady income, which is helpful if you’re looking for something more predictable.

Bonds vs. Mutual Funds and ETFs

Instead of buying individual bonds, you can invest in a bond mutual fund or ETF. These funds group many bonds together, which spreads out the risk. They’re managed by professionals and are often easier to buy and sell than single bonds. Just remember that fund fees and market prices affect your overall return.

Risks of Bond Investing

Like any investment, bonds come with some risks. A prominent example is interest rates. When rates go up, bond prices usually fall. There’s also credit risk, which is the chance the issuer can’t pay you back. Inflation can chip away at the value of your interest payments over time as well, and reinvestment risk means you may not find the same returns when your bond matures. Understanding these risks helps you make informed decisions and find bonds that match your goals and comfort level.

How to Start Investing in Bonds

Getting started with bond investing doesn’t have to be complicated. Buying individual bonds and exploring funds are both great starting points. Depending on your goals, experience, and how involved you want to be, there are a few ways to begin diversifying your investment portfolio with bonds. 

Direct Purchases

One way to invest in bonds is to buy them directly through a brokerage or government website like TreasuryDirect. Doing so gives you more control over what you own, including the issuer, maturity date, and interest rate. However, some bonds have minimum investment amounts, and managing your own might take more research. 

Bond Funds

Bond mutual funds and ETFs let you invest in many bonds at once. This is an easier way to start because you’re not picking individual bonds. These funds are managed by professionals and often offer more flexibility and liquidity than buying bonds directly. They also help you spread out risk by holding a variety of bonds in one place. 

Working with a Financial Advisor

A financial advisor can help if you’re unsure of where to start. They’ll look at your financial goals, timeline, and comfort level with risk. They’ll then recommend bond investments that make sense for your situation. They also help monitor your portfolio over time and make changes when needed. 

Wrapping Up: What to Know Before You Buy Bonds

Bonds can be a strategic addition to your investment plan, especially if you’re looking for stability, regular income, or a way to balance out more unpredictable assets like stocks. While they come in different forms and carry more risks, understanding the basics helps you make decisions that align with your long-term goals.

Frequently Asked Questions

What is a bond? 

A bond is a loan made to an issuer, like a corporation or government. In exchange, the issuer pays you regular interest over a set period and returns your original investment, the principal, at the bond's maturity date.

How do bonds work? 

When you buy a bond, you lend money to an issuer. The issuer pays you interest (coupons) at regular intervals. When the bond reaches its maturity date, the issuer repays your original investment. Bond prices can also rise or fall on the secondary market.

How long is a bond good for? 

A bond’s lifespan is its "maturity," which is the date the issuer repays the principal. This can range from short-term (a few months or years) to long-term (30 years or more). The maturity date is fixed when the bond is issued.

What does a $1,000 bond mean? 

A $1,000 bond typically refers to its face value, or par value. This is the amount the issuer promises to repay you when the bond matures. While its market price may change, the face value is the amount paid back at the end.

Can you lose money in bonds? 

Yes. If you sell a bond before maturity when interest rates have risen, its price may be lower than what you paid. There is also credit risk, which is the chance the issuer could default and fail to repay your principal investment.

What is the typical return on bonds? 

A bond's return is called its yield, which varies based on its credit quality and prevailing interest rates. Safer bonds like U.S. Treasuries offer lower yields, while riskier corporate bonds generally offer higher yields to compensate for the added risk.

Are all bonds a good investment? 

Whether a bond is a good investment depends on your goals and risk tolerance. They are excellent for generating stable income and diversifying a portfolio, but they still carry risks. Matching the bond type (corporate, municipal, etc.) to your financial objective is key.

How to start investing in bonds? 

You can start by buying individual bonds through a brokerage or TreasuryDirect. For easier diversification, you can invest in bond mutual funds or ETFs, which hold a wide variety of bonds. A financial advisor can also help create a personalized strategy for you.

Are bonds better than stocks? 

Neither is better; they serve different purposes. Stocks offer higher growth potential but more risk. Bonds typically provide more stability and predictable income. Many investors use both to create a balanced portfolio, managing risk while seeking returns.
