The „Bail-In Tracker“ is a joint project of the Research Center SAFE in Goethe University Frankfurt’s House of Finance and the German business daily Börsen-Zeitung. The project is funded by the VolkswagenStiftung in the context of the project “Science and Data Journalism”. It aims at examining the bail-inable debt of large European banks. In particular, researchers will exploit data on the bond issuances of these banks over the last years and construct a data set which represents the bail-inable debt over several years. Moreover, this data set will be presented on this website and updated regularly to represent the current level of bail-inable debt for these banks. This data set will also serve as a basis for several scientific investigations. Results will be published as academic studies and also highlighted in the Börsen-Zeitung for a broader audience. The “Bail-In Tracker” shall build a bridge between academic research and journalism and enhance the general understanding of the bail-in topic.
