Resolution planning: organisation and liabilities: every EBA validation rule in plain words (RESOL1)

Resolution reporting gives resolution authorities the data to plan how a failing bank could be resolved in an orderly way: its legal entities, liabilities, critical functions and links to market infrastructure. MREL and TLAC reporting shows whether it holds enough capacity to absorb losses. Both use EBA templates and travel in XBRL.

EBA's 4.2 package has 122 validation rules for it. Line4 Check runs 88 of them (1,791 written-out checks): 48 can block a filing and 40 are warnings. EBA has switched 26 off. 8 are not run yet.

8 rules not run yet

Their EBA formulas need parts of the XBRL formula language Line4 Check does not cover yet. Your authority's validation runs them.

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.
