The Quarterly Financial Accounts (QFA) present a complete and consistent set of quarterly financial data for all sectors of the Irish economy. They provide comprehensive information on the financial and investment activities of households, non-financial corporations, financial corporations, government and the rest of the world. The whom-to-whom tables provide information on the interactions between these sectors. They show the financial-interlinkages of the economic sectors for a subset of financial instruments. For deposits, debt securities, listed shares and mutual fund shares and units the tables provide the perspective of a respective debtor sector vis-a-vis all resident creditor sectors and the Rest of the World. The tables show nominal and not-seasonal and calendar adjusted stock and transaction values on a quarterly basis.
