The 1994–1995 Mexican peso crisis occurred with the presence there of a “new” financial force, namely nonbank private funds. Mexico's economic reforms have in recent years led to massive amounts of highly liquid (and volatile) foreign capital inflows. As the country further embraces market-based principles, long- and short-term capital will flow at an even larger scale across its border, subjecting providers as well as recipients to greater risks. This paper examines the trends in both the “traditional” as well as the “new” forms of capital inflows for the period 1981–1996. Our analysis should help the two sides of this issue: foreign investors to be better prepared in managing future economic challenges, and emerging economies—including several in Southeast Asia that suffered Mexican-style exchange-rate crises in 1997—to implement more appropriate policies, especially as they pertain to currency stability.
