Corporations, in addition to municipal governments and the U.S. Teasury, all issue bonds.

Bonds are issued to raise financial capital. The issuer gets money today in exchange for a promise to repay funds in the future.

Anyone who buys a bond is a lender, since bond buyers pay money now in exchange for repayment in the future. The U.S. Treasury, banks in different countries, and private citizens all buy bonds.
