Purpose: The purpose of this study is to increase the understanding of how a bank?s features and internal factors have affected its choice of method in calculating the capital requirement.Theoretical and Empirical Method: The research strategy of this study has been of a qualitative nature with a deductive approach. The choice of method was depth interviews with respondents from a targeted sample of Swedish banks. These respondents were chosen based on the knowledge they possess as key employees in the capital requirement process and their involvement in choosing their banks? method for calculating the capital requirement. The interviews were semi-structured, with open questions that allowed a dialogue with the respondents in which they could express their opinions and knowledge regarding the factors affecting their banks? choice of method.Theoretical Approach: The study is based on the new institutional economics theory of how institutions affect organizational behavior. It?s also based on earlier research within the regulation Basel II by, among others, Hakenes and Schabel (2011), Rime (2005) and Wahlström (2009).Conclusions: The results of this study show that banks have identified different factors that affect their choice of calculation method for the capital requirement. The choice the banks are facing is to keep the standardized method, develop an advanced internal based method, create partnerships with other banks or focus on alternative clientele portfolios. The two factors that were considered to be have the greatest significant for the choice of calculation method were resources associated with the implementation of the IRB approach models and how the banks? clientele portfolio was designed. How these were distributed and to what extent they influenced the choice was highly individual for the chosen banks.
