Volatility transmission between the oil price, the exchange rate and the stock market index

Mokengoy, Mardochée Bopo 23 April 2018 (has links)
Ce mémoire analyse la transmission de volatilité entre le prix du pétrole, le taux de change et l’indice boursier au Canada et aux États-Unis de 1999/01/04 à 2014/03/21. En utilisant un modèle MGARCH-BEKK, nos résultats montrent qu’au Canada, il existe une transmission bidirectionnelle de volatilité entre le taux de change $US/$CAD et l’indice boursier TSX, une transmission positive de l’indice boursier au prix du pétrole, ainsi qu’une transmission négative du taux de change au prix du pétrole. Les résultats suggèrent également que ces relations ne sont pas stables dans le temps. Pour les États-Unis, le modèle estimé ne satisfait pas la condition de stationnarité de la covariance pour la période totale et la sous période 1999/01/04 – 2002/10/08. C’est pourquoi nous considérons uniquement les résultats des sous périodes 2002/10/09 – 2008/05/30 et 2008/06/02 – 2014/03/21. Il ressort qu’il existe des transmissions de volatilité, mais que celles-ci ne sont pas stables dans le temps. / This thesis analyzes the transmission of volatility between oil prices, exchange rates and stock market indices in Canada and in the USA for the period 1999/01/04 – 2014/03/21. Using a multivariate GARCH – BEKK model, we find that in Canada, there is a bidirectional transmission of volatility between the exchange rate $US/$CAD and the stock market index TSX, a positive transmission from the stock market index to the oil price and a negative transmission from the exchange rate to the oil price. We find also that these relationships are not stable over time. For the USA, the model estimated does not satisfy the condition of covariance stationarity for the entire sample and the sub sample 1999/01/04 – 2002/10/08. So we consider only results for sub samples 2002/10/09 – 2008/05/30 and 2008/06/02 – 2014/03/21. Results show that there are transmissions of volatility, but here again, these relationships are not stable over time.
