What are Bonds?

A bond is a type of fixed-income investment where an investor loans money to a borrower (typically a corporation or government entity) in exchange for regular interest payments and the return of their principal investment.

Key Characteristics

Fixed Income: Bonds offer a fixed rate of return in the form of interest payments.
Principal Repayment: The borrower repays the principal amount (face value) at maturity.
Maturity Date: The specific date when the bond expires and the principal is repaid.
Credit Risk: The risk that the borrower may default on interest payments or principal repayment.

Types of Bonds

Government Bonds: Issued by governments to finance public projects or refinance debt.
Corporate Bonds: Issued by companies to raise capital for various business purposes.
Municipal Bonds: Issued by local governments and municipalities to finance public projects.
High-Yield Bonds: Issued by companies with lower credit ratings, offering higher yields to compensate for the increased risk.

The 2022 lesson: why duration matters

Bonds are often described as the safe part of a portfolio. Then 2022 happened. As the Federal Reserve raised rates to fight inflation, the broad U.S. bond market lost about 13 percent for the calendar year, its worst year on record. Long-term Treasury bonds did far worse, falling close to 30 percent. Stocks fell too, so the classic balanced portfolio had nowhere to hide. Anyone who thought bonds could not lose money learned otherwise in a single year.

The mechanism is simple and worth memorizing. When interest rates rise, existing bonds with lower coupons become less attractive, so their prices fall until their yields match the new market. How far a bond’s price falls depends on its duration, which is roughly the number of years until you get your money back. A useful rule of thumb: a bond fund with a duration of six years loses about six percent for every one-point rise in rates. That is why long-term bonds cratered in 2022 while short-term bonds barely wobbled.

The practical takeaway is to match your bond duration to your time horizon. Money you need in a year or two belongs in short-term bonds or Treasury bills, where rate moves barely register. Money you will not touch for a decade can sit in intermediate bonds and ride out the swings. Duration is not a detail for professionals. It is the single number that tells you how much a bond investment can hurt you when rates move.

Benefits

Regular Income: Bonds provide a predictable stream of interest payments.
Low Risk: Government and high-grade corporate bonds typically offer lower risk compared to stocks.
Diversification: Bonds can help reduce overall portfolio risk by adding a fixed-income component.

Risks

Interest Rate Risk: Changes in interest rates can affect bond prices and yields.
Credit Risk: The risk of borrower default, which can result in loss of principal.
Liquidity Risk: The risk of not being able to sell a bond quickly or at a fair price.

Investing in Bonds

Individual Bonds: Investors can purchase individual bonds directly from the issuer or through a broker.
Bond Funds: Mutual funds or exchange-traded funds (ETFs) that invest in a diversified portfolio of bonds.
Bond Ladders: A strategy where investors purchase bonds with staggered maturity dates to create a regular income stream.

By investing in bonds, individuals can add a fixed-income component to their portfolio, providing regular income and relatively lower risk compared to other investments.

Bonds vs. bond funds

There is one more distinction that trips up beginners. An individual bond has a maturity date: if you hold it to the end, you get your principal back (assuming no default), no matter what rates did in between. A bond fund has no maturity date. It constantly buys new bonds as old ones mature, so there is no date on which you are guaranteed your principal back. That is why a bond fund can lose money even if you hold it patiently.

Most investors should still use bond funds. Building your own diversified ladder of individual bonds takes serious money and effort, and a fund gives you hundreds of bonds for a tiny expense ratio. Just go in with the right expectation. A bond fund is not a savings account with a better yield. It is a portfolio of loans whose market value moves every day, and its job is to pay you interest and diversify your stocks, not to never lose money.
