Therefore, the paper starts with a brief explanation of the American banking system, its importance and the general structure, in order to prove sound previous knowledge to better understand the following theories. In the third chapter a comprehensive overview of the financial crises during the Great Depression is given, all significant aspects that could have influenced or even triggered the financial crises are explained and defined, and different views of researchers are provided. The financial crisis’ main focus of the Great Depression was on the extraordinary high banking failure rates and therefore the main objective of this paper is to investigate whether it would have been possible to forecast the high failure rates on the basis of the bank’s balance sheets before the Great Depression or not. Therefore, a comprehensive definition, its emergence in connection with the Basel Accords, and different measurement methods are provided. Due to the fact that the economy has to face financial crises again and again it is time to figure out models that might forecast financial crisis. Therefore, characteristics of former financial crisis have to be analysed in a manner that tell whether it would have been possible to forecast banking failures. In this study it will be investigated whether banks’ balance sheet could be a foundation of such theories. For this reason, the study is subdivided into three major parts. First of all, it is tested whether investments of banks influence banking failure rates at all by means of a regression model. In the second part of the study it is invest
