I want to know the answer to the following question:
What is one of the reasons experts believe contributed to the volatilaty in oil prices in 2008?
All the background I'm provided with is that "Experts debate the causes, with some attributing it to speculative flow of money from housing and other investments into commodities, some to monetary policy, and some to the increasing feeling of raw materials scarcity in a fast-growing world, leading to long positions taken on those markets, such as Chinese increasing presence in Africa.". Is that enough to answer the question?
Answer: yes
