Abstract

En este articulo examinamos el comportamiento del mercado cambiario en Mexico, el cual se caracteriza por movimientos extremos muy frecuentes ocasionados por la informacion generada dentro del mercado financiero y el entorno macroeconomico internacional. Modelamos estos movimientos extremos utilizando un proceso varianza gamma, el cual nos permite capturar el sesgo y el exceso de curtosis de los rendimientos del tipo de cambio. Concluimos que, en general, este proceso ajusta mejor a los datos que el movimiento browniano geometrico – basado en la densidad normal– y nos permite estimar con mayor precision el Valor en Riesgo (VaR). Mostramos, ademas, que el ajuste mejora conforme aumenta la ventana temporal utilizada para calcular los rendimientos del mercado cambiario. Finalmente, realizamos un backtesting del VaR mediante la prueba de Kupiec.
