Value-at-Risk (VaR) Brazilian Real and currencies of emerging and developing markets

Abstract

Globalization has been responsible for increasing exposure to risks related to currency factors for companies and countries. The literature has addressed the issue of currency volatility in emerging and developed countries without a consensus on such a dynamic and there are few studies that estimate and place the risk of the Brazilian real. Thus, this study aimed to measure the risk of the Brazilian exchange rate, as well as test the hypothesis that there is a significant difference in volatility between currencies of emerging and developing countries. Through the parametric VaR set to extreme values ​​distributions, it was observed that the Brazilian real presented at greater risk of exchange rate. The results also showed that the distributional assumptions do not seem to have any specific pattern when faced emerging and developed countries and also emerging countries showed less volatility, reflecting the preponderance of factors external to the foreign exchange market in determining the risk of some currencies.
