Financial integration and exchange rate determination: a Brazilian case study

Abstract

This paper investigates the impact on exchange rate determination of two recent changes in developing and emerging countries’ financial integration: first, the rising volume and heterogeneity of short-term portfolio flows; second, foreign investors’ increased exposure to domestic rather than foreign currency assets. In its analysis of Brazil, the paper shows that both changes have potentially destabilizing implications for the exchange rate and may create the risk of self-feeding bubble dynamics leading to large and sudden swings in exchange rates. The results have important implications for the regulation of international capital movements and choice of exchange rate regime.
