The problem is that even people who don't feel strongly about the future of the USA mostly know that other people will be buying dollars as a safe haven and so they themselves buy. You make money getting in early on where the moneys going, not where the truth already is. Also, most people aren't contrarian investors, they won't get in to something unless is already looks like it is going in a confirmed direction, if silver went up $5 many more people would get in on it even though it represents less value than it does now. Stackers are almost always contrarian, trying to buy at the bottom when everyone else says it's over. Well...that's not quite true, they just put ounces on whether people say things are looking good or bad, which is a type of contrarian position I guess, contrary to all popular wisdom.
I am a little surprised that the dollar didn't get a bigger bump than it did. I was betting on USD denominated PMs going sideways but with a 3 or 4% jump in the DXY.
From what I gather watching the financial news channels and reading a few different things most investors are just not trading either way, you could still get a positive move if the EU/IMF/Greeks make waves indicating that things are going to get messy.
