Early Indicators Of Currency Crises Review Of Some Literature

Financial crises have become relatively frequent events since the beginning of the 1980s. They have taken three main forms: currency crises, banking crises, or both - so called twin crises. As the number of developed economies, developing countries, and economies in transition experienced severe financial crashes researchers are trying to propose a framework for systemic analyses. That is why attempts to advance the understanding of features leading to the outbreak of financial crisis as well as the reasons of vulnerability have become more and more important. In recent years a number of efforts have been undertaken to identify variables that act as early warning signals for crises. The purpose of this paper is to provide some perspective on the issue of early warning signals of vulnerability to currency crises. In particular, it is aimed at presenting and highlighting the main findings of theoretical literature in this area. An effective warning system should consider a broad variety of indicators, as currency crises seem to be usually associated with multiple economic and sometimes political problems. Indicators that have proven to be particularly useful in anticipating crises and received empirical support include the development of international reserves, real exchange rate, domestic credit, credit to the public sector, domestic inflation, and structure and financing of public debt. Other indicators that have found support are trade balance, export performance, money growth, M2/international reserves ratio, foreign interest rates, real GDP growth, and fiscal deficit. Many of the proposed leading indicators have been able to predict particular crises, however, only few have showed ability to do so consistently. Generally, economic models can be said to be more successful in predicting crises that erupt because of weak fundamentals, which make country vulnerable to adverse shocks. They are less likely in anticipating crises due to selffulfilling expectations or pure contagion effects. So far economists are only able to identify situations in which an economy could face the risk of a financial crisis. This is most because of the well-known fact that if we knew the crisis would have already occurred. Warning indicators seem to be unlikely to predict crises in precise way but their analyses can provide extended information about impending problems what enables to take preventive measures.

This paper examines the empirical evidence on currency crises and proposes a specific early warning system. This system involves monitoring the evolution of several indicators that tend to exhibit an unusual behavior in the periods preceding a crisis. When an indicator exceeds a certain threshold value, this is interpreted as a warning “signal” that a currency crisis may take place within the following 24 months. The variables that have the best track record within this approach include exports, deviations of the real exchange rate from trend, the ratio of broad money to gross international reserves, output, and equity prices.

This paper reviews the literature on financial crises focusing on three specific aspects. First, what are the main factors explaining financial crises? Since many theories on the sources of financial crises highlight the importance of sharp fluctuations in asset and credit markets, the paper briefly reviews theoretical and empirical studies on developments in these markets around financial crises. Second, what are the major types of financial crises? The paper focuses on the main theoretical and empirical explanations of four types of financial crises—currency crises, sudden stops, debt crises, and banking crises—and presents a survey of the literature that attempts to identify these episodes. Third, what are the real and financial sector implications of crises? The paper briefly reviews the short- and medium-run implications of crises for the real economy and financial sector. It concludes with a summary of the main lessons from the literature and future research directions.

The abruptness and virulence of the 1997 Asian crises have led many to claim that these crises are of a new breed and thus they were unforecastable. This paper examines 102 financial crises in 20 countries and concludes that the Asian crises are not of a new variety. Overall, the 1997 Asian crises, as well as previous crises in other regions, occur when the economies are in distress, making the degree of fragility of the economy a useful indicator of future crises. Based on this idea, the paper proposes different composite leading indicators of crises, which are evaluated in terms of accuracy both in-sample and out-of-sample.

This study reviews the literature on the origins of currency and banking crises. It presents empirical tests on the performance of alternative early-warning indicators for emerging-market economies. The book also identifies crisis-threshold values for early-warning indicators.
