The European Banking Authority (EBA) releases today the interim results of its investigation on risk-weighted assets (RWAs) in the banking book aimed at identifying any material difference in RWA outcomes and at understanding the sources of such differences. This report, which illustrates the outcomes of the first phase of the investigation, is part of a wider EBA analysis on the consistency of RWAs, whose ultimate objective is to better understand the differences in the calculation of RWAs and, if need be, to formulate the necessary policy solutions to enhance convergence between banks and to improve disclosure.
