What is a Bond in Finance : Meaning, Types, Features & Benefits

A bond in finance is a fixed-income investment where people lend money to a company or government for a set time at an agreed interest rate. The borrower returns the money with interest after the period ends.

For example, Meena bought a ₹10,000 bond from the Indian government for 5 years at 6% yearly interest. Each year, Meena gets ₹600 as interest, and after 5 years, she gets back her ₹10,000. This way, Meena earns money safely.

Here is how Meena's bond works:
 

Bonds help people grow money steadily and help governments or companies raise funds.

The Mechanism of Bonds

Bonds are like formal loans. When you buy a bond, you lend your money to a company or the government, and in return, they promise to pay you interest regularly and return your money after a fixed time. This setup is common for raising money for schools, roads, or expanding businesses.

Let’s understand this with an example:

Ravi, a school teacher, buys a ₹5,000 bond from a company for 3 years at a 7% interest rate. Each year, the company pays Ravi ₹350 as interest (7% of ₹5,000). After 3 years, the company returns its ₹5,000. So, Ravi earns money without taking much risk.

A Closer Look at the Core Bond Categories

There are four main types of bonds you will find in the market. Each has a different purpose and comes from a different type of issuer. Here's a simple table to help you understand them with examples:

In the U.S., Fannie Mae issues bonds to give money for home loans.

How Interest Rates Affected Bond Prices?

In 2022, many central banks like the US Federal Reserve raised interest rates sharply, moving from around 1.5% to over 4% (e.g. US Aggregate bond yields rose from 1.7% to 4.65%).

As those rates climbed, older bonds with lower coupons dropped in value. For instance, PIMCO  held long-term bonds bought when yields were just 1–2%. When yields rose, the market value of those bonds fell sharply, creating paper losses for PIMCO.

Similarly, an investor in a 7% government bond in India found that in 2023, new bonds were offering 8%- 8.5%, so selling the older bond early meant accepting a lower price.

This scenario shows that:
