Bond

is a loan you make to a government or corporation. In exchange, they promise to pay you interest (coupon) regularly and return your principal at maturity.

Bonds are called 'fixed income' because they pay a fixed interest rate. They're generally less risky than stocks but offer lower returns.

Quick answer

A bond = you loan money to a company or government. They pay you interest regularly and return your principal at maturity. Bonds are safer than stocks but offer lower returns. Bond prices fall when interest rates rise.

A bond is a loan to a government or company that pays periodic interest and returns principal at maturity; its price moves inversely to interest rates.

What Is a Bond?

A bond is essentially an IOU. When you buy a bond, you're lending money to the issuer—whether that's the US government, a corporation, or a municipality. In return, they pay you interest and return your principal at maturity.
