TEXT OF STORY
KAI RYSSDAL: Oil continued its generally downward ways today. Or at least we think it did. Since crude started climbing last year there's been all kinds of speculation about speculation in the market. So the Commodity Futures Trading Commission has spent most of this year trying to find out what's going on.
Today the Wall Street Journal reports that as part of its investigation the CFTC is looking into whether oil companies have been manipulating prices themselves. The theory is that by reporting that their reserves are lower than they really are, that false shortage would force prices higher.
From New York, Ashley Milne-Tyte reports.
ASHLEY MILNE-TYTE: The Commodities Futures Trading Commission didn't have any comment on the Journal's story. It would say only that its oil market investigations are ongoing.
Tom Wallin is president of Energy Intelligence. He says what's certain is that the oil companies report their inventory levels to the government, which then publishes the numbers.
TOM WALLIN: Every week when these numbers come out they're watched by the market and people in the futures market trade directly off of these numbers and they make immediate assumptions about what the trend in the market is, based on those inventory numbers.
So if the inventory numbers are low, traders buy and the price goes up. The oil company itself can then theoretically sell its oil for more than it would otherwise. Reporting inaccurate data to the government is against the law.
Amy Meyers Jaffe directs the Baker Institute Energy Forum at Rice University. She says the big oil companies already make billions of dollars producing oil.
Amy Meyers Jaffe: And it's just hard for me to believe that the companies would engage in illegal activity to make a little bit of money. Why would they risk the scandal?
Tom Wallin is also skeptical. He says a company could under- or over-report and potentially move the market once or twice.
WALLIN: It would be very, very hard to do this in a systematic way. And it would be inconceivable to me that this could be the cause of a . . . sort of a major surplus in the price of oil.
He says the U.S.'s method of collecting this information is more thorough than that of most countries.
