"They" aren't letting the price of gold rise. "They" have no choice. Things got away from them.
First the Howe/Bolser Report was released to the press. The next day Bush fires O'Neill and Lindsay, and an 8 week bull run in gold takes off.
Then "they" raise the margin requirements for gold options trading, thus forcing the little players to cover while "they" hold on to their shorts and dump more gold on the market. "They" force a good correction -- which they hoped would turn into a rout.
Then this Insight article comes out, and for the first time a major reputable publication covers a story that only the samizdat Internet sources covered. Gold went up today, and I believe this story will drive it much farther.
Of course, when the price explosion comes, "they" will blame it on Iraq. You can see what excuses "they" are lining up to avoid a scandal, congressional investigation and jail time. I'll be interested in seeing how many of them board their private planes to head for places with no extradition treaty.
