The facts

Who files
Credit institutions. The Bank lists this return among the periodic information it requires from credit institutions, and rule 62.3 of Circular 2/2016 refers to their obligations to send the Bank the statements of Implementing Regulations (EU) 2021/451 and 2021/453, in addition to the Bank's own statements. Source
How often
Quarterly, as the Bank's list states for template G 01.00 [3900], citing Article 20 of Implementing Regulation (EU) 2021/451. Source
Deadline
Not stated on the Banco de España page for this return or in its template list, which cite the EU implementing regulation for the reporting frequency. See the EBA entry for the EU remittance dates. Source
Format
XBRL-XML. XBRL-XML files sent through the Bank's SIF system (web upload or signed and encrypted email). The Bank publishes Spanish extensions of the EBA and SRB taxonomies that keep the business content unchanged: one module covers both individual and consolidated data, told apart by the dimension 'Agrupacion', and the EBA filing indicators are replaced by the Bank's own preamble listing the statements sent. All facts of one data type must use one decimal precision so the Bank can convert the file to xBRL-CSV for the European authorities; a mismatch is a serious error and the file is rejected (I.E. 2008.02).

Templates (0)

The library lists no templates for this return.

EU return: the templates and instructions are defined by the EBA. See the library's EBA entry eba/gsii (docs/eba/gsii.md). Spanish firms use the EBA's templates and taxonomy, through the Banco de España's Spanish extension. Source

Validation rules

The BdE publishes the checks it runs on this return. They could not be counted from the published material. Software can run them exactly as published. Source

How they are written: EBA validation rules in the EBA reporting framework (see the EBA entry); Banco de España cross-check file ('Correlaciones y cuadres') with rule code, severity and formula.

The rules are the EBA's (see the library's EBA entry eba/gsii). The Bank's cross-check workbook for this return lists 28 distinct rule codes, 17 owned by the EBA and 11 by the Banco de España itself, each with its severity (blocking 'Error restrictivo', non-blocking 'Error no restrictivo' or a request for public information) and a formula. Under I.E. 2008.02, statements that fail the validations are, as a general rule, rejected automatically and treated as not filed.

How they were counted

Not counted here: the EBA's validation rules apply (see eba/gsii).

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