This is a clear example of how the quality of the overall statistical system is higher than what the mere sum of independent products would be, were such products not well-connected. Micro data as the Holy Grail We can all agree that statistics have been undergoing a revolution in the last few years. Important technological advances have increased the ability to process huge amounts of data and productivity in this area has surged: policymakers and analysts have more and more information and details at their fingertips and now have the possibility of applying  1  more sophisticated models, designing more refined economic policy responses and answering more complex questions. Some of these changes stem from the experience of the Great Financial Crisis of the last decade. Then it was felt that only the availability of detailed information on economic agents’ positions (including cross-border ones) would allow the relevant policy authorities to thoroughly analyse the exposures of an increasingly interconnected global financial system and to better understand the monetary policy transmission mechanism and the massive deleveraging that followed. To close these gaps, the Eurosystem promoted a number of projects based on granular information. These included AnaCredit (to build up a Central Credit Register at the European level), the Securities Holding Statistics Database (which contains exhaustive security-by-security information on European portfolios) and Money Markets Statistical Reporting, where daily information at the transaction level is collected from financial institutions. In Spain, we also learned the lesson.
