The European Banking Authority (EBA) published today a second report on the consistency of risk weighted assets (RWAs) in the residential mortgage portfolio. The report, which is part of a wider ongoing EBA work on comparability of RWAs, illustrates the findings of a so called “drill-down analysis”, an investigation on the extent to which the most commonly used risk drivers influence the variability in risk weights. Overall, the analysis confirmed that risk parameters, such as loan to value, are drivers of RWAs. However, there are differences in how the banks reflect such drivers in RWAs.
