Credit bonds, also known as "unsecured bonds", refer to bonds issued only by the credit of the issuing company without specific assets as collateral. It is also a bond issued by a subject other than the government, and it is agreed to repay the cash flow with a certain principal and interest. Specifically, it includes corporate bonds, corporate bonds, short-term financing bonds, medium-term notes, separate convertible bonds, asset-backed securities, subordinated bonds and other varieties.

At present, there are three main types of bonds in the bond market: national debt, convertible bonds and credit bonds.

Compared with secured bonds, holders of unsecured bonds bear greater risks, so they often demand higher interest rates. Generally, only enterprises with higher credit ratings issue credit bonds.
