This book provides a legal analysis of the regulation of bank-based financial conglomerates from a structural, commercial, and regulatory perspective. It includes a comparative analysis of the regulation of bank-based financial conglomerates from the standpoint of the three jurisdictions that established a distinct regulatory model, i.e. Germany, the UK, and the US. At the same time, it analyses which banking resolution strategy is most appropriate for different models, taking into account four factors applicable to bank insolvency. The book further examines the types of capital structure associated with each model, and in particular how BBFCs have influenced industry developments in Germany, the United Kingdom, the United States, and the EU. While there are several books that focus on the regulation of banks, insurance companies, and securities firms, this book will include the first analysis of BBFC from a structural, commercial, and resolution standpoint, analysing not only the three major jurisdictions but three different BBFC models, and will be of particular interest to students, researchers, and professors of banking and financial institutions.
