The recent dramatic fall in oil prices has renewed the interest in the importance of shocks in the oil price volatility. This column presents results from new research on the role of shocks and speculation on oil prices. The authors find that when speculation is short in duration, it has the weakest impact on oil prices and demand shocks have the largest. However, when speculation is allowed to have short- and long-term effects, it is the main contributor to the volatility of oil prices.
