According to a new ECB Regulation, there have been light changes in the calculation of aggregated interest rates in chapter19 (Tables 19.3 to 19.10)
Chapter 19. Interest rates (excluding those published in financial markets chapters)
As from the present edition of the Boletín Estadístico, the method for obtaining national aggregate interest rates has changed slightly owing to the recent entry into force of a new ECB Regulation relating to this statistic. In particular, the new method introduces different treatment of the base data, which are compiled from a survey, to estimate the aggregate of national monetary financial institutions. Given that this new method is not compatible with the obtaining of aggregates broken down by different groupings of institutions, the tables referring to the deposit institutions grouping cease to be published in this chapter and only those referring to the aggregate of credit institutions and credit financial intermediaries will be published.
