Actually I think that the early pressure on gold and silver had more to do with setting up the field before that announcement: "US official says US would be ready to back larger European financial stability fund via increased IMF commitments." As a result EURUSD surged as well as pretty much everything else. Anyone doubt that GS and JPM didn´t know of this in advance so they could cover their shorts and the Euro and going long. As the Mogambo would say this investing stuff is easy!
