The conference attracted a wide range of policy- makers, including a number of members of the ECB’s Governing Council and users and compilers of statistics from central banks, supervisory authorities, statistical institutes, international institutions, academia, the media and the financial industry. The conference provided an opportunity to discuss ways of strengthening the information basis for the fulfilment of the mandates given to the ECB and to the European Systemic Risk Board. The topics included: i) the supply of statistics in multi-purpose data collection, for both monetary policy and macro-prudential oversight; ii) the use of micro data in macro measurement and iii) issues related to the use of economic statistics by financial market participants. I firmly believe that good data are essential for making good decisions. Producing high-quality statistics on the financial sector is a core activity of central banks, both for policy-making and for communicating their decisions and thus also for the credibility of our actions. Today, the key challenges for the central bank statistical community concern the growing need for accurate, timely and granular data, and the necessary availability of adequate resources to address complex organisational and conceptual changes in statistics. It is vital to collect more data consolidated at the level of banking groups or insurance groups and more data to monitor unregulated financial institutions and markets. Aggregates alone are not sufficient, as policy-makers and analysts need access to the underlying micro data owing to the increased policy relevance of and emphasis being put on, data “outliers” and so-called “tail risks”. Moreover, since the boundaries of the phenomena under investigation are changing quickly, a high degree of adaptability among statistics’ compilers is required. An important issue in this respect concerns the confidentiality of individual data, and supervisory data in particular. In this context, conference participants discussed how to find the right balance between the need for confidentiality and the possibility of data sharing. There is also an increasing need for statisticians to present their results in a meaningful way and to communicate clearly with users, the press and the general public. Data revisions in particular have rightly or wrongly captured the limelight and need to be explained carefully. All this entails good cooperation not only at the European level but also at the national level between central banks, statistical institutes and supervisory authorities, and requires efficient data transmission and processing between different organisations and consistency with initiatives taken at the global level. As witnessed by the quality of the contributions collected in this book, the Sixth ECB Statistics Conference has made a significant contribution to the better 7 understanding of the statistical demands created by the financial and sovereign debt crises. I hope this will provide valuable food for thought for future initiatives by statisticians aimed at meeting the needs of policy-makers in the fields of monetary policy and financial stability, and I trust that other readers of this book will equally benefit from these insights.

This introduction provides a summary of the contributions and discussions contained in the rest of this volume. The conference started with an introductory speech given by the ECB President Mario Draghi, and it was structured into four sessions: 1. Future challenges for monetary statistics in a changing environment. 2. How fit for use are statistics for macro-prudential oversight. 3. Micro foundations of macro data. 4. Financial markets participants as users of economic statistics. Andreas Dombret, member of the Executive Board of the Deutsche Bundesbank, delivered a keynote speech between the second and third sessions, and Jose Manuel González-Páramo, member of the ECB’s Executive Board, gave the closing speech. The conference offered also a preview of a book on European System of Central Banks (ESCB) statistics to mark the 20th anniversary of the ESCB Statistics Committee, which was presented by Peter Bull. In his opening address, Mario Draghi reflected on the key statistical challenges arising from the financial crisis and the role of statisticians. He then mentioned selected initiatives aimed at filling in data gaps, bearing in mind constraints related to reporting burdens and data confidentiality. The key challenges concern the need for very timely and granular data, and complex conceptual changes in statistics. For instance, traditional monetary statistics are unable to gather information on financial groups that operate across borders and through non-bank subsidiaries.
