Interest rate risk in the banking book: every EBA validation rule in plain words (IRRBB)

IRRBB reporting tells a supervisor how a change in interest rates would hit a bank’s economic value and its earnings. Every institution files the headline template (J 01.00) each quarter; larger ones add the detail behind it. The EBA publishes the templates and the validation rules, and the returns travel in XBRL.

EBA's 4.2 package has 206 validation rules for it. Line4 Check runs 151 of them (3,601 written-out checks): 0 can block a filing and 151 are warnings. EBA has switched 55 off.

The rules, by template

Each rule in plain words, its code in brackets. Open one for what to do if your filing fails it. A rule that reads more than one template is listed under the first. Rules are warnings unless marked blocking.
