The issuer makes a clear distinction between the two. The federal government, acting through The Bureau of the Fiscal Service, is the issuer of treasury securities. In contrast, the corporate bond issuers are various private organizations with various credit ratings to denote their legitimacy. The most reliable kind of bonds in terms of trustworthiness are U.S. Treasury securities. They do, however, provide cheap interest rates. Corporate bonds, in contrast, offer greater interest rates but may also be riskier, depending on the issuer's credit standing.
