  1. The Academy of Economic Studies Doctoral School of Banking and Finance Contagious Currency Crises - Dissertation Paper- Student: Dumitru Delia Supervisor: Prof. Moisã Altãr Bucharest, July 2003

  2. Objectives: • The Currency Crisis from Russia, august 1998: testing for the existence of a contagion effect; • Determine whether the macroeconomic similarities between countries represented a channel of contagion; • Determine the domestic economic fundamentals that influenced the pressure on the exchange market.

  3. Definitions: • A currency crisis is usually defined as a situation in which an attack on the currency leads to a sharp depreciation of the exchange rate. • Testing for contagion means searching whether the probability of a crisis in a country at a point in time increases the probability of crises in other countries after controlling for the effect of political and economic fundamentals.

  4. Krugman’s Model (1979) - crises were caused by weak economic fundamentals; Obstfeld’s Model (1986)- self-fulfilling crises; Early Warning System Models: -Kaminsky, Lizondo and Reinhart, 1998; -Eichengreen, Rose and Wyplosz, 1996; Gerlach and Smets (1995)- trade links; Goldfajn and Valdes (1995) – illiquidity; Eichengreen, Rose and Wyplosz (1996)- trade and similarity links; Sachs, Tornell and Velasco (1996)- contagion due to similar economic features. Litherature Review Three generations of models referring to currency crises: Contagious Currency Crises

  5. The Data: • Countries: Russia, Ukraine, Latvia, Lithuania, Estonia, Poland, Hungary, the Czech Republic, the Slovak Republic, Romania and Bulgaria; • Quarterly Data: Q1:1993- Q1:2003; • Date Sources: International Financial Statistics, IMF-World Bank-OECD-BIS joint table.

  6. When did speculative attacks take place? • Index of exchange market pressure: where: ei,t - the price of a USD in country’s i currency at time t; Δii,t - the variation of short term interest rate; Δri,t - the variation of international reserves; α, β, γ - weights.

  7. When did speculative attacks take place? • Extreme values of EMP: 1, if EMPi,t≥1.5σEMP+μEMP Crisisi,t= 0, otherwise. • Results:

  8. The Model • Equation: • Fundamentals: - domestic credit; - current account; - CPI growth; - employment; - GDP growth; - unemployment; - money; - government deficit; - ratio of short term debt to reserves; - deviation of the real exchange rate from the trend.

  9. The Model • Determine the macroeconomic similarities whose existence might be a potential channel for contagion. • Being “similar” means having similar macroeconomic conditions; • Similarity weights: • Variables: domestic credit, money, CPI, output growth and current account.

  22. Conclusions • A speculative attack in Russia seems to have increased significantly the odds of an attack in 6 of the countries included in the sample - it does not represent a definitive proof of contagion; • The hypothesis that attacks spread to other countries where economic policies and conditions are similar is not always confirmed – similarities are difficult to capture in a weighting scheme. • The fundamental causes of speculative attacks differ across countries- it is very difficult to find a set of fundamentals underlying all crises.
