Flow-of-funds accounting permit to monitor the financial sector in terms of flows and stocks and to analyze its relationship with the real sector. These show inter-sectoral financial flows, capture balance sheet positions and all financial transactions by instrument, type and economic sector. In this paper we explain the methodology for the construction of flow-of-funds accounts and we exemplify their use for two source cases of study: the Mexican Crisis (1994-1995) and the Asian Crisis (1997-1998). Using similar sources of data, the same methodology and approach for the construction of all the flow-of-funds matrices allow comparisons among countries relating to the impact, manifestations of these crisis episodes and policy reactions to confront their effects. The use of homogeneous data and methodology also permits to trace contagion effects between countries.
