Treasury bonds are medium or long term debt securities issued by sovereign governments or their agencies. Typically they carry a lower rate of interest than corporate bonds. In addition to serving as a source of finance for governments, treasuries are used to manage the money supply in the money market operations of central banks.

Money market instruments are short term debt instruments, such as certificates of deposit, commercial paper and certain bills of exchange. They are highly liquid and are sometimes referred to as "near cash".

Eurosecurities are securities issued internationally outside their domestic market. They include eurobonds and euronotes. Eurobonds are characteristically underwritten, and not secured, and interest is paid gross. A euronote may take the form of euro-commercial paper (ECP) or euro-certificates of deposit.

Hybrid
Hybrid securities combine some of the characteristics of both debt and equity securities.

Preference shares form an intermediate class of security between equities and debt. If the issuer is liquidated, they carry the right to receive interest and/or a return of capital in priority to ordinary shareholders.

Convertibles are bonds which can be converted, at the election of the bondholder, into another sort of security such as equities.
