Leading indicators of country risk and currency crises: the Asian experience
构建了一个基于金融变量的动态因子模型，用于提前预警货币危机，并以泰国、印度尼西亚和韩国为例验证了模型在1997年危机中的有效性，对央行防范危机有参考价值。
Most emerging capital markets in recent years adopted a system that narrowly pegs their currencies? exchange rates to the U.S. dollar. While such a system has a number of advantages, it makes a country vulnerable to shocks in mobile international capital markets and can lead to reactive strategies that can drive the country into a currency crisis and inflationary recession. ; This article aims to construct an early warning system for international currency crises using financial variables reflecting investors? expectations and banking distress, which are highly sensitive to changes in the economic environment. The authors use a dynamic factor model that switches between two regimes?representing periods of relative calmness and periods prone to currency crises?to construct leading indicators of country risk and currency crises. ; The method is applied to evaluate the model?s in-sample and out-of-sample performance in anticipating currency crises in the last two decades in Thailand, Indonesia, and Korea. The model successfully produces early signals of these crises, particularly the most severe one, which occurred in 1997. ; The study?s success in signaling future currency crises in real time demonstrates that the model?s ?country risk? indicators can be informative tools that allow central banks to take preemptive counterpolicy measures to avoid a crisis or mitigate its severity.
