GUIDELINE OF THE EUROPEAN CENTRAL BANK
of 26 September 2012
on the data quality management framework for the Centralised Securities Database
(ECB/2012/21)
(2012/689/EU)
THE GOVERNING COUNCIL OF THE EUROPEAN CENTRAL BANK,
Having regard to the Statute of the European System of Central Banks and of the European Central Bank, and in particular Articles 5.1, 12.1 and 14.3 thereof,
Having regard to Council Regulation (EC) No 2533/98 of 23 November 1998 concerning the collection of statistical information by the European Central Bank (1),
Whereas:
|
(1) |
The Centralised Securities Database (CSDB) is a single information technology infrastructure, which is operated jointly by the members of the European System of Central Banks (ESCB), including national central banks (NCBs) of non-euro area Member States where such NCBs voluntarily participate in the operation of the CSDB. The CSDB stores item-by-item data, in particular, data on securities, their issuers and prices. |
|
(2) |
Data are collected from various sources, including from ESCB members, certain commercial data providers, the public domain and administrative sources, and transmitted to the CSDB. There is a risk, however, that such input data may be inaccurate or incomplete. The CSDB system is able to reconcile partially inconsistent input data from different sources, and can detect incomplete or missing data. It automatically compounds input data from various overlapping sources to the extent possible into a complete and high quality single record. |
|
(3) |
The overall quality of data in the CSDB can only be assessed at the level of output data rather than at the level of individual sets of input data. To ensure the completeness, accuracy and consistency of output data, to the extent possible, it is necessary to define a framework for data quality management (DQM) to be applied to output feed data, a subset of output data that can be used to support the production of statistics or other uses. Output feed data is provided to NCBs no later than seven working days following the end of each calendar month. |
|
(4) |
Some output feed data also include attributes such as prices or income-related information which are expected to fluctuate over time. These attributes are automatically verified by the CSDB system through the application of statistical algorithms. Only attributes specified in Annex I for each DQM target are subject to verification by competent authorities in accordance with this Guideline. The full list of attributes constituting the supported feeds is set out in Annex II. |
|
(5) |
The CSDB DQM framework should be applied to output feed data regardless of the source of input data. It should lay down the responsibilities of the euro area NCBs for the quality of output data in the CSDB and, where relevant, those of the European Central Bank (ECB). |
|
(6) |
The CSDB DQM framework should be based, first, on DQM targets that represent indicators for assessing the quality of output feed data and, second, on DQM metrics that identify and prioritise, for each respective DQM target, the output feed data that need to be verified. It should also be based on DQM thresholds that define the minimum level of verification that needs to be conducted in relation to a DQM target. |
|
(7) |
Given the absence of benchmark data, DQM targets do not always identify errors in output feed data but can only identify cases where manual verification of output feed data is needed. |
|
(8) |
Since the CSDB is operated jointly by all ESCB members, they should all aim to follow the same DQM standards. Moreover, non-euro area NCBs are in the best position to carry out DQM on the data related to issuers residing in their respective Member States. While it is recognised that guidelines adopted by the ECB may not impose any obligations on non-euro area NCBs, Article 5 of the Statute of the European System of Central Banks and of the European Central Bank applies to both euro area and non-euro area NCBs. Non-euro area NCBs should therefore design and implement all the measures that they consider appropriate in order to carry out DQM in accordance with this Guideline. |
|
(9) |
To improve the quality of output data, data source management (DSM) should be carried out with the aim of identifying and correcting repetitive and structural mistakes in input data directly with the data provider, |
HAS ADOPTED THIS GUIDELINE:

Conceptual background:
Concept: For each country of residence the metric shall identify the instruments in clash groups and shall relate them as a percentage share in terms of counts or in terms of monetary amounts to all instruments for that country. Coverage: The metric shall cover all instruments in the CSDB. |
Target 3a assesses the correct identification of the issuer population. Where there is a disagreement on the issuer of an instrument, i.e. instruments in ‘clash groups’, such instruments shall not exceed the DQM threshold. |
Explicit attributes: Issuer identifier used for grouping. |
Amounts outstanding in euro referring to instruments in clash groups, expressed as a percentage share of all instruments. |
||||||||||||||||||||||||||||||
|
Target 3b: Data accuracy – support correct sector allocation and data extraction by issuer |

Concept: For each country of residence the metric shall identify the instruments in stand-alone groups and shall relate them as a percentage share in terms of counts or in terms of monetary amounts to all instruments for that country. Coverage: The metric shall cover all instruments in the CSDB. |
Target 3b assesses the correct identification of the issuer population. Where there is no reliable information on the issuer of an instrument, i.e. instruments in ‘stand-alone groups’, such instruments shall not exceed the DQM threshold. |
Explicit attributes: Issuer identifier used for grouping. |
Amounts outstanding in euro referring to instruments in stand-alone groups, expressed as a percentage share of all instruments. |
||||||||||||||||||||||||||||||
|
Target 4: Data accuracy – amount outstanding of debt securities including certificates |
Concept:
|
Target 4 compares CSDB output data to external benchmark data. Unverified and unexplained differences between aggregated CSDB data and the respective information from ECB SEC or other reliable benchmarks shall, subject to the availability of such benchmark data, not exceed the DQM threshold for the same reference date for each of the following ESA issuer sectors:
|
Explicit attributes: Amount outstanding in euro, market capitalisation in euro. Implicit attributes: issue date, maturity date, currency, issuer ESA sector, country of residence. |
Amounts outstanding or market capitalisation in euro, expressed as a percentage difference between CSDB and external benchmark. |

|
Target 5 compares CSDB output data to external benchmark data. Unverified and unexplained differences between aggregated CSDB information and the respective information from ECB SEC or other reliable benchmarks shall not, subject to the availability of benchmark data, exceed the DQM threshold for the same reference date for each of the following ESA issuer sectors:
|
Explicit attributes: Amount outstanding in euro, number of shares outstanding for quoted shares. Implicit attributes: nominal currency, issuer ESA sector, country of residence, price value for quoted shares (outlier check only). |
Amounts outstanding or market capitalisation in euro, expressed as a percentage difference between CSDB and external benchmark. |
||||||||||||||||||||||||||||||
|
Target 6: Data accuracy – issuer classification |
Concept: The metric shall rank issuers for each country of residence/issuer sector combination pursuant to their total security-based liabilities (equity and debt combined). The metric shall also indicate absolute rank changes between different issuers to facilitate identification of significant outliers in outstanding amounts or market capitalisation. The country of residence and sector classification of the issuer shall be verified up to the DQM threshold. Coverage: The metric shall cover all investment fund shares, equity and debt securities which do not have a maturity date older than three months. |
Target 6 assesses the statistical classification of issuers. The statistical classification of the issuers up to the DQM threshold shall be verified for each of the following ESA issuer sectors:
|
Issuer ESA sector, country of residence. |
Amounts outstanding or market capitalisation in euro, expressed as ‘capitalisation’, i.e. amounts outstanding plus market capitalisation per issuer. |
(1) The numbering of categories reflects the numbering introduced in the proposal for a regulation of the European Parliament and of the Council on the European System of national and regional accounts in the European Union, COM(2010) 774 final.
