On 26 February, the European Banking Authority (EBA) released the interim results of its investigation on Risk-Weighted Assets in the Banking Book aimed at identifying any material difference in risk-weighted asset outcomes and at understanding the sources of such differences. This report, which illustrates the outcome of the first phase of the investigation, is part of a wider EBA analysis on the consistency of risk-weighted analysis, whose ultimate objective is to better understand the difference in the calculation of risk-weighted assets and, if need be, to formulate the necessary policy solutions to enhance conversions between banks and to improve disclosure.
