This paper presents the Flow-of-Funds Analysis applied to improve knowledge about financial flows in Brazilian economy. We develop asset-liabilities-matrixes (ALM) to the years 2004 and 2009, which are disaggregated in 10 institutional sectors to obtain a broadly overview of the specific structure of flows in Brazilian financial system. From flow-of-funds indexes we could illustrate the role of each institutional sector in the system, than we could highlight that during the period, there was a movement to increase the participation of others financial firms in financial system, excluding government-sponsored banks, while enterprises and government were working as financial intermediaries in an informal market.
