​This supplement to the Quarterly Bulletin presents the revised national financial account for South Africa from 1992 to 2009 – the period under review. The revised statistics for this period replace all relevant annual and quarterly national financial account matrices published earlier. The purpose of this supplement is to restate the national financial account data over the revision period in order to present a more accurate analysis of the economy.This revision was necessitated by two main factors, namely (1) the technical improvement in the compilation of flow of funds in 2006 that revealed minor imbalances in all flow matrices finalised previously and (2) the recent revision of South Africa’s national accounts data as a result of rebasing. The balance sheets of institutional sectors have remained largely unchanged over the revision period, resulting in broadly unchanged aggregate financial assets and liabilities at the sectoral level. The revised data indicate a decline of about R70,8 billion in total flows over the revision period – bringing total flows to R1,3 trillion in 2009 from R218 billion in 1992. The data also demonstrate that only 11 per cent of the sectoral net financing positions have changed signs during the revision period.The approach followed in this supplement is to briefly outline the national financial account compilation methodology in section 2. The sectoral analysis, where each sector is discussed in brief over the period under review, is presented in section 3 and section 4 concludes this supplement. All the amounts mentioned in this supplement are flows, unless otherwise indicated.
