According to an investigation by a congressional subcommittee70% of all trading in West Texas Intermediate crude on the New York Mercantile Exchange is by speculative traders compared to 37% in 2000. The subcommitte findings are based on data obtained from federal commodity futures regulators. So are the Saudis right that speculators in futures trading ar playing a big part in the oil price increases or is the administration position correct that this is not a factor at all? This provides backing to the Saudi position, the IMF position and the position of McCain and Obama, the 2 presidential candidates. And there are calls to close a loophole that prevents oversight by the government over this kind of trading.
