A bond — also called a “debt security” — is similar to an IOU. Companies and governments issue bonds as a way to borrow money from investors. This guide explains more about what a bond is, the advantages and risks of bonds, and how issuing bonds can help a corporation.
As mentioned above, a bond is similar to a formal “IOU.” When someone buys a bond, they’re essentially lending money to an organization (such as a business or a government). In exchange, that organization promises to pay the lender an agreed-upon interest rate for a specified time. They also agree to repay the principal, also known as the face or par value of the bond, by a certain date.
There are four primary categories of bonds sold in U.S. markets. This section explores each category.
Corporate bonds are issued by companies. Sometimes, companies issue bonds rather than seek bank loans for financing certain projects or investments. In situations like this, a bond benefits both shareholders and the corporation.
Municipal bonds are issued by states and municipalities. One municipal bond advantage over other types of bonds is the potential tax benefit for investors.
A government bond is a bond issued by the U.S. Treasury. The entire category of bonds issued by a government treasury is often called “treasuries.” Government bonds issued by national governments may be referred to as sovereign debt.
Agency bonds are issued by government-affiliated organizations. Agency bond examples include bonds issued by Fannie Mae and Freddie Mac, the U.S. Congress-created federal mortgage companies.

Bonds can provide investors with a predictable income stream. Unlike equity securities that may lose value, investors know the exact value of a bond. This is why bonds are sometimes called “fixed-income instruments.” Additionally, the interest from municipal bonds is generally exempt from federal income tax and may be exempt from state and local taxes.
There are a few risks that come with owning bonds. These include:
If someone’s considering buying a bond, it’s prudent to do their homework to make an informed decision. Companies should also consider the risks before issuing bonds.
Bonds are debt securities that are issued by companies and governments and sold to investors. As with most debt, bonds have maturity dates, at which point the principal amount must be paid back in full.
