EFFECT OF THE 2007/2008 CRISIS ON INTERNATIONAL VOLATILITY TRANSMISSION IN BRAZILIAN CAPITAL MARKET

Abstract

With the increasing globalization of world, financial markets around the world began to show further integration. This relationship between markets has implications as a term that has attracted the attention of professionals and academics, the transmission of volatility. Thus, this work has as scope to analyze the transmission of volatility in the Brazilian market. For that, we used a multivariate Garch model with BEKK parameterization. Based on this model, we estimated the bilavariate relationships between the Brazilian market, represented by the Bovespa index, and the U.S. markets, Argentine, Mexican and Chinese, also with outcome approached by representative indexes of January, 4 of 2000 to march, 30 of 2010, totaling 2667 observations. The sample was divided into three parts, representing the periods of before, during and after the sub-prime crisis of 2007/2008. The results allow concluding that during the 2008 crisis, in general, there was a change in the direction of the volatility transmission between Brazilian market and the others studied, with Brazil passing to exercise greater influence, because it suffered less consequence due to the financial crisis. Moreover, after the period of turmoil caused by the crisis of 2008, the relationship between the volatility of the Brazilian market with the rest became less asymmetric than in the period before the crisis.
