In this article we analyze, first, why funds continued to flow towards emerging economies while fundamentals in host countries had been deteriorating before the Asian crisis (a rising external deficit, with a significant liquid component; appreciating exchange rates; low capital formation, particularly in Latin America), and why funding remains dry for long since 1998; the role of the nature of the predominant agents and of a process of flows rather than one shot building of stock of foreign capital are stressed. Then, the analysis focuses on the interrelations of capital flows and fiscal, monetary and exchange-rate policies. Finally, some policy implications are presented for boom-and-bust stages of cycles led by capital flows.
