Statistical Data and Metadata Exchange (SDMX)

The various sets of BIS statistics (international banking and financial statistics, data on global liquidity, credit, property prices, exchange rates and payment systems), require the transmission, processing and dissemination of vast amounts of statistical data and related methodological information (so-called metadata).

On behalf of the central banks involved in its statistical work, the BIS is a sponsor of the Statistical Data and Metadata Exchange (SDMX) initiative, together with the ECB, Eurostat, the IMF, the OECD, the World Bank and the UN.

Together with IT service architecture and IT tools, the SDMX technical standards and content guidelines enable data and metadata to be disseminated and shared efficiently. The first version of the standards was finalised in 2004 and has been approved as an ISO Technical Specification (ISO/TS 17369:2005). The most recent version (SDMX 2.1) was approved by the SDMX sponsors in 2011.

In March 2016 an IFC Report was published which presents the results of a survey on central banks' use of the SDMX (Statistical Data and Metadata eXchange) standard, which was organised by the SDMX Global Conference 2015 organising committee. The report shows that SDMX is increasingly used among central banks for the exchange and dissemination of statistical data and metadata.

At the beginning of 2016, the SDMX sponsors approved a "Roadmap 2020" presenting a vision of where SDMX is heading in the next few years and outlining a series of strategic objectives. These priorities are further developed in an Action Plan covering the period until end of 2018.

A concrete example of the utilisation of SDMX standards is the recently set-up data exchange between the same seven international organisations that are IAG members (see Communication Note).
