Bonds are seen as safe investment whereas shares represent the risky chance of quick profits. However, bonds are not entirely free of risk. All issuers, whether bank, corporate or sovereign are affected by different factors and risks. Not only financial but also political or environmental variables play a role. This master thesis provides the different approaches to an evaluation of the bond categories.Central problem statement of this thesis is the different approaches within the assessment and analysis of the bank, corporate and sovereign bonds. Furthermore it discusses the various methods of analysis of the bond types and their application is illustrated. These issues lead to the following research questions: What are the differences between bank bonds, corporate bonds and sovereign bonds? What is the role of different characteristics in the evaluation process of the three bond types? What methods are used for evaluation of the bank, corporate and sovereign bonds? What methods are used for analysis of the bank, corporate and sovereign bonds?The introductory section of the work deals with the basics of bonds. Definitions, variations, risks, ratings are the topics of this chapter. The bulk of the work begins with chapters on bank, corporate and sovereign bonds. The differences between the variants are identified and the rating process is demonstrated. Another chapter is devoted to the valuation of fixed rate and variable rate bonds. Completion of the main part is the section about the different approaches for analysis of bonds.
