The facts

- How often
- Monthly (rule 67.1 table (Circular 4/2017 as published in the BOE in 2017; Circular 1/2025 later changed some statements)). Under Circular 1/2025, FI 105 is sent only by institutions with derivatives of a cumulative notional amount of EUR 150 billion or more. Source

- Format
- XBRL-XML. XBRL-XML file built on the Bank's own taxonomy, sent through the SIF system (web upload or signed and encrypted email to correo@procesos.bde.es) with a Banco de España electronic certificate; the file names the reporting module and lists the statements sent in a preamble (I.E. 2008.02). Taxonomy 'reservados_m_2026_03' (monthly confidential statements) in the Bank's list of taxonomies in force. Source

Validation rules
915 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.
How they were counted
Distinct rule codes listed in 'FI_Reservados_individuales_mensuales_FI_100_FI_105_Cuadres.pdf' (file dated 2026-07-06 by the server), each shown with its number of evaluations and its formula; 9 rule codes whose validity period ended before 11 November 2026 were left out (924 listed in all).
Counts are in the BdE's own unit, so they are not comparable with other regulators' counts.
