Did Speculation Fuel Oil Price Swings?, 60 Minutes: Speculation Affected Oil Price Swings More Than Supply And Demand - CBS News: "'Approximately 60 to 70 percent of the oil contracts in the futures markets are now held by speculative entities. Not by companies that need oil, not by the airlines, not by the oil companies. But by investors that...don't actually take delivery of the oil."
"Gilligan said. "I tease people sometimes that, you know, people say, 'Well, who's the largest oil company in America?' And they'll always say, 'Well, Exxon Mobil or Chevron, or BP.' But I'll say, 'No. Morgan Stanley.'"
Morgan Stanley isn't an oil company in the traditional sense of the word - it doesn't own or control oil wells or refineries, or gas stations. But according to documents filed with the Securities and Exchange Commission, Morgan Stanley is a significant player in the wholesale market through various entities controlled by the corporation.
It not only buys and sells the physical product through subsidiaries and companies that it controls, Morgan Stanley has the capacity to store and hold 20 million barrels. For example, some storage tanks in New Haven, Conn. hold Morgan Stanley heating oil bound for homes in New England, where it controls nearly 15 percent of the market. "
Interesting. I should warn you that the video is not ground breaking (for as anyone knows speculation obviously played a role in price swings), but worth including as it shows how far investment banking has gone from traditional investment banking and it has some good insights in the market for oil.
