This article briefly describes the structure of sectoral accounts for the economy under the framework of the System of National Accounts. It outlines a Reserve Bank work programme to support the development of financial accounts and flow of funds analysis. These accounts would enhance our understanding of financial behaviours and inter-sectoral relationships within the economy. The article also discusses the development of a full household sector balance sheet and presents estimates for a number of items that are not currently covered in the Reserve Bank’s published tables of household assets. New experimental estimates of the equity held in unincorporated businesses, and households’ equity in unlisted incorporated businesses add around $170 billion to previously published estimates of household assets.
