Abstract

Esta investigación proporciona una explicación congruente y consistente de por qué Petróleos Mexicanos (pemex) ha incrementado el uso de las coberturas financieras en los últimos años, tanto en el precio del petróleo crudo como en el tipo de cambio y las tasas de interés. Particularmente, en este trabajo se examina la eficiencia de la cobertura con opciones put sobre el precio del petróleo crudo realizadas en 2009. Se simula la ganancia o pérdida que se tendría para garantizar un precio de 70 dólares por barril (de la mezcla mexicana) presupuestado por el Gobierno Federal. Asimismo, se utiliza un modelo garch (1,1) para estimar la volatilidad del precio del petróleo para realizar una simulación mark to market./ This research provides a consistent and coherent explanation of why Petroleos Mexicanos (pemex) has increased the use of financial hedges, in recent years, in crude oil prices, exchange rates and interest rates. Particularly, in this paper we examine the efficiency of hedging through the put option on the price of crude oil, in 2009. The gain or loss incurred to guarantee a price of $ 70 per barrel (of the Mexican mix) budgeted by the federal government is simulated. Moreover, we use a garch (1,1) model to estimate the volatility of oil prices for a mark to market simulation.
