Who's to blame for rising oil prices? Speculators - Yahoo! News
http://news.yahoo.com/s/csm/20110427/cm_csm/379828 Oil prices have continued to rise despite mixed news on oil supply and demand, a diminishing chance of Saudi oil disruptions, and Japan’s human and economic catastrophe. Such price movements were even more dramatic when oil prices rocketed from $50 in February 2007 to over $147 per barrel in July 2008. Rapid swings in price, which are hard to connect to traditional market forces, indicate the influence of speculation.
