Rubric What is granular data? Micro- or granular data? • Micro data refers to the individual statistical or reporting unit Operational system Granular data closer to operations Main statistical aggregates Granular data (e. g. information contract by contract, or counterparty by counterparty) • ESCB’s focus lies lately on granular data Microdata in ESCB banking statistics www. ecb. europa. eu

Rubric What is microdata? Pros and cons of granular data (and for whom) Cons Pros – Potentially very rich information source (users, producers) • • distributional information other microfoundations of aggregates – Could significantly decrease the reporting burden (producers, reporting agents) – Allows for producing tailor-made statistics (users, producers) – Integrated data models could help in overcoming the silo-mentality (users, producers) Microdata in ESCB banking statistics – detailed knowledge of various instruments and contracts is needed (producers) – data at various levels of granularity could exploit very different properties (producers) – confidentiality issues (producers, reporting agents) – in an ESCB content: could result in additional burden for NCBs (producers) www. ecb. europa. eu

Rubric ESCB activites relating to granular data collection Examples of ESCB Projects relating to granular data • Centralised Securities Database (CSDB) • Securities Holdings Statistics (SHS) • Analytical Credit dataset (Ana. Credit) Supporting reporting agents in the production of statistics • Banks’ Integrated Reporting Dictionary (BIRD) – not reporting! Microdata in ESCB banking statistics www. ecb. europa. eu

Rubric Discussion points • The move towards more granular data brings potentially benefits for reporting agents, producers and users, but also significant challenges • Are Central Banks (and Statistical Institutes) ready to move to the industrial scale production that is needed? • What kind of competences, IT infrastructure, international standards and legal framework will be needed in the future to deal with large scale, detailed information that the move to granular data is bringing?

Rubric ECB-UNRESTRICTED Centralised Securities Database (CSDB) Reference information on individual securities relevant for ESCB purposes • Up-to-date, complete, accurate, consistent security-by-security information • Allows compilers to base their interactions with reporting agents on the most granular level in the field of securities statistics • Multi-purpose system supporting the production of various central banking statistics (insurance companies, investment funds, financial vehicle corporations, securities issuance) The ECB is preparing the CSDB to handle the Legal Entity Identifier (LEI).

Rubric ECB-UNRESTRICTED Securities Holdings Statistics (SHS) Statistical dataset on securities holdings, developed since 2009 • Collection of security-by-security data either directly or via custodian reporting • Interoperability with the CSDB Two main components for different analytical purposes • Sectoral data – Holdings of euro area residents broken down by the country and sector of the holder (collected via direct reporting) – Securities issued by euro area residents held by non-euro area residents (collected with the help of custodians) • Reporting Banking Groups (RBGs) data (direct reporting) Microdata in ESCB banking statistics www. ecb. europa. eu

Rubric Analytical credit datasets (Ana. Credit) as an important building block of an integrated approach • Ana. Credit will cover the need for granular data on credit and credit risk (mainly loans), whose current availability, e. g. from Central Credit Registers, is rather incomplete and heterogeneous across EU countries • It will bring increased coverage, and especially harmonisation in underlying concepts and definitions standardisation • Multipurpose; should support a wide range of users – – – Monetary policy analysis and operations Risk control and collateral management Financial stability Micro/macro supervision Economic analysis and research Statistical production Microdata in ESCB banking statistics www. ecb. europa. eu

Rubric Banks’ Integrated Reporting Dictionary (BIRD) • The BIRD proposes a standardised model for organising the banks’ internal data warehouses in an integrated way • It also covers transformations to obtain reports that banks need to transmit ü The BIRD consists of documentation, it is not an IT tool ü The application of the BIRD by the banks is strictly voluntary ü Responsibility for the correctness of the data remains with the banks ü The BIRD implies no additional reporting requirements Microdata in ESCB banking statistics Top FAQs www. ecb. europa. eu
