Validation rules

384 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 'BG_IM_IPH_Cuadres.pdf' (file dated 2024-04-01 by the server), each shown with its number of evaluations and its formula.

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