Geopolitical tensions, opec news, and the oil price: A Granger causality analysis. RAE [online]. ISSN Are oil price forecasters aware of these tensions? Is there a difference between news coming from OPEC countries versus other major what is the meaning of dominant characteristic exporters? In this article, why is granger causality important analyse the influence of geopolitical tensions, news, and events in major oil producers on the Brent oil price, its forecasts, and the dispersion of those forecasts.

We why is granger causality important test cause and effect task cards pdf hypotheses by introducing and making use of a unique media-based measure of geopolitical tensions accounting for supply crunches and expansions for the period, by means of Granger causality. We found evidence suggesting that overall geopolitical tensions affect the current level of oil price, its forecasts, and the dispersion of those forecasts.

More remarkably, when separating between OPEC and non-OPEC news, we found that the former affect oil price forecasts and its consensus, and at the same time, the current oil price determine oil-based news on OPEC countries. Moreover, non-OPEC news affect the current and future oil price level why is granger causality important neither the forecast nor the dispersion of those forecasts its affected by the level.

All these results imply that geopolitical tensions in a broader sense affect oil prices, and OPEC news should be read jointly with other geopolitical tensions as oil price drivers -and not as an isolated news generator affecting oil prices. This weakens the hypothesis of OPEC as a price setter in the global oil market whose behaviour, in turn, seems a matter for forecasters.

These results are important suggesting that, in order to keep track of oil price dynamics, one needs to account for a more general context of geopolitical tensions beyond OPEC countries, relying on signals and externalities that are not necessarily based on economic rationale. En este artículo, analizamos la influencia de las tensiones geopolíticas, noticias, y eventos en los principales productores de petróleo sobre el precio del petróleo Brent, sus proyecciones, y la dispersión en torno a esas proyecciones.

Encontramos evidencia sugiriendo que las tensiones geopolíticas, en general, afectan el nivel actual del precio del petróleo, sus proyecciones, y la dispersión en torno a esas proyecciones. Notablemente, al separar entre las noticias de la OPEP y las no OPEP, encontramos que las primeras afectan las proyecciones del precio del petróleo y su consenso y que, al mismo tiempo, el precio actual del petróleo afecta las noticias en los países de la OPEP.

Esto debilita la hipótesis de la OPEP como un fijador de precios en el mercado mundial del petróleo cuyo comportamiento, a su vez, parece ser relevante para los pronosticadores. Servicios Personalizados Revista. Erasmo Escala Teléfono: 56 2 Fax: 56 2 rae uahurtado. Como citar este artículo.
