1 rule EBA has switched off
EBA has switched these off, in its 4.2 severity package or since then in its list of validation rules (latest update 12 October 2026): they do not apply to 4.2 filings.
Checks like this one, run at the point of submission, are the first step to real-time supervision. See every return on EBA validation rules in plain words.
