Bond are formal certificates issued by the companies or government agencies acknowledging the indebtedness. To the investors, they are proofs of investment. In the current scenario the terms bonds and debentures are being used interchangeably. The public sector enterprises, financial institutions and the private corporates approach the public to finance their requirements through loans. They can issue either short- or long-term bonds and debentures. The bond market consists of three different categories of issuers - government owned Financial Institutions (FIs), Public Sector Units (PSUs) and private corporates.
