The European Banking Authority (EBA) published today an update to the XBRL taxonomy that Competent Authorities should use for the remittance of data under the EBA Implementing Technical Standards (ITS) on supervisory reporting. The revised taxonomy will be used for reference dates from 31 March 2018 onwards.
The documents published today include the following:
A set of XML files forming the XBRL taxonomy;
A description of the architecture of the XBRL taxonomy;
A description of the Data Point Model (DPM), of which the taxonomy is a standardised technical implementation, including both a database and document representations, along with a description of the formal modelling methodology by which the DPM is defined.
Reports with reference dates as of 31 March 2018 onwards are to use the new taxonomy set (2.7), which is related to the April 2017 framework release.
Background and legal basis
The taxonomy defines a representation for data collection under the reporting requirements related to own funds, financial information, losses stemming from lending collateralised by immovable property, large exposures, leverage ratio, liquidity ratios, asset encumbrance, additional liquidity monitoring metrics, supervisory benchmarking and funding plans. As part of enhancing regulatory harmonisation in the EU banking sector and facilitating cross-border supervision, uniform data formats are necessary to enable comparable data on credit institutions and investment firms across the EU.
Although, the EBA XBRL taxonomy was primarily developed for data transmission between Competent Authorities and the EBA, many authorities have been using it for the collection of supervisory reporting from the credit institutions and investment firms they supervise. In this respect, the taxonomy proposed by the EBA will lead to greater efficiency and convergence of supervisory practices across Members States. In addition, it will facilitate the supervisory process, allowing supervisors to identify and assess risks consistently across the EU and to compare EU banks in an effective manner.
