Validation rules

17 rules, as counted from the BdE's published material. They are written for people to read; software cannot run them as published. Source

How they are written: PDF report of cross-checks ('Informe de cuadres y relaciones' or 'Correlaciones y cuadres') giving each rule code, its number of evaluations, tolerance and formula.

Under I.E. 2008.02, statements that fail the validations are, as a general rule, rejected automatically and treated as not filed; part of the checks are also published in XBRL in the Bank's taxonomies.

The rules, on bde.es

How they were counted

Distinct rule codes listed in 'Clausulas_suelo_Cuadres.pdf' (file dated 2021-10-13 by the server), each shown with its number of evaluations and its formula; 2 rule codes whose validity period ended before 11 November 2026 were left out (19 listed in all).

Counts are in the BdE's own unit, so they are not comparable with other regulators' counts.
