5. Geopolitical flashpoints.In the not too distant past, a small supply disruption would send oil prices skyward. In early 2014, for example, violence in Libya blocked oil exports, contributing to a rise in oil prices. In Iraq, ISIS overran parts of the country and oil prices shot up on fears of supply outages. But since then, geopolitical flashpoints have had much less of an effect on the price of crude. During the last few weeks of 2014, violence flared up again in Libya. But after a brief increase in prices, the markets shrugged off the event. Nevertheless, history has demonstrated time and again that geopolitical crises are some of the most powerful short-term movers of oil prices.
