NEW YORK ( TheStreet) -- Gold price manipulation is the most controversial theory that has circulated among gold bugs for 20 years. Conspiracy theorists think that gold prices have been illegally suppressed over the last two decades by central banks and governments. GATA or Gold Anti-Trust Action Committee is the biggest complainant. Central banks reportedly have 32,000 tons of gold, with the International Monetary Fund accounting for 2,800 tons. Under the Washington Agreement on Gold, its members can only sell a maximum of 400 tons a year thereby restricting the amount of gold in the open market place. GATA argues that central banks in actuality have less than 15,000 tons of gold and that the missing gold has been secretly sold into the market preventing gold prices from rising to their actual price, which helps the country's paper currency, bonds and interest rates. The suppression theory means that global economies are in worse financial shape than investors think and that gold should be bought as the ultimate safe haven. The New York Post recently reported that the the Commodities Futures Trade Commission and the Department of Justice have launched criminal and civil probes into JPMorgan's trading in the silver market to determine if the investment bank depressed the silver price for their advantage. There are also rumors circulating that a major New York law firm will launch a similar lawsuit against the investment bank. I interviewed Chris Powell, secretary and treasurer of GATA to get the facts of this alleged manipulation. Can you explain the basics of silver/gold manipulation? Powell : Gold, and to a lesser extent, silver are currencies. Governments have intervened in the gold market in the open throughout history. Our complaint is that more often now they're doing it surreptitiously as a mechanism of supporting their currencies, supporting government bonds and suppressing interest rates. So can you break it down, how the government is doing it on the sly as you said? Powell: Yes, the manipulation of the gold market now is achieved through two mechanisms mainly. One is the outright sale or leasing of central bank gold reserves to add gold to the market. The other is the sale of futures and options, gold derivatives by the big investment banks that have special relationships with the central banks, particularly with the Federal Reserve. These are essentially naked short positions in the gold and silver markets.
