While there has been considerable research on currency crises, relatively little attention has been given to whether they are successful or not. We investigate this question for a set of 32 emerging market economies for the period 1980–2014. In the literature, many different measures of currency crises have been used, but almost all use some variants of exchange market pressure indices that look at changes in exchange rates, international reserves, and often also interest rates. These vary mainly in their specific specifications such as how to weigh the different variables. Therefore, to check the robustness of our results we use six different specifications. A second type of measure is also sometimes used. These focus only on large depreciations of exchange rates. While often called measures of currency crises they are really only measures of currency crashes. We thus take this approach as a measure of successful attacks. Using a wider range of thresholds than studies such as Lavean and Valencia’s, a well-known dataset of different types of financial crises, we still find that the vast majority of speculative attacks are not successful.

Although derivatives were developed for the treatment of some diseases, such as risks and volatilities, ironically, as experienced in the 1990s, they, themselves, created them as sometimes “adverse effects” of hedging or with deliberately harmful purposes of speculation. This paper aims to analyze the role of financial derivatives in the emerging markets financial crises of the 1990s. In this regard, it deals with the Mexican case through a VAR-GARCH approach. The paper found that financial derivatives had an increasing impact on the currency crises of Mexico. This was an immediate destabilizing effect on the volatility of the spot exchange rates. Si bien los derivados fueron desarrollados para tratar ciertas enfermedades como los riesgos y la volatilidad, irónicamente, como se vivió en la década de 1990, ellos mismos crearon en ocasiones esos problemas como “efectos secundarios” de la cobertura, o bien, con intenciones deliberadamente dañinas de especulación. Este artículo busca analizar el rol de los derivados financieros en las crisis de los noventa dentro de los mercados emergentes. Así pues, se trata el caso mexicano mediante un enfoque VaR-GARCH. El artículo encuentra que los derivados financieros tuvieron un impacto creciente en las crisis monetarias de México. Éste fue un efecto desestabilizador inmediato sobre la volatilidad de las tasas de cambio al contado.

In research on the political economy of exchange rates, a good understanding of who will endorse and who will oppose certain exchange-rate policies is central to understanding how actual exchange-rate policies are made and how the global exchange-rate system changes over time. Since existing classifications of exchange-rate level preferences have several shortcomings, this article proposes a new and more nuanced strategy for identifying preferences on exchange-rate valuation. This approach takes into account the complex interrelationship between exchange-rate and monetary policy, and the effects of these policies on balance sheets. In addition, the approach accounts for the dynamics of preference formation and change. Comparative case studies of currency crises in Hong Kong, South Korea, Thailand, and Taiwan show that considering actors' vulnerabilities to exchange-rate and interest-rate changes enhances understanding of their exchange-rate level preferences. The case studies also indicate that societal preferences affect policy outcomes. Exchange-rate stability was maintained in countries where private actors' vulnerabilities to depreciation were high. However, when pressure intensified, exchange rates were subsequently depreciated in countries where vulnerabilities to a monetary tightening exceeded the potential costs of depreciation.
