The European Banking Authority (EBA) today published four principles to support supervisory efforts in assessing the representativeness of COVID-19-impacted data for banks using internal ratings based (IRB) models. These principles will be part of a supervisory handbook, which the EBA will publish later in 2022 with the objective to ensure a harmonised approach in the use of COVID-19 data, especially where the use of moratoria and other public measures may have led to changes in default rates.
