Eric deCarbonnel seems to think so:
I am certain the US is less than a month away from a currency collapse. The fed and treasury are not even taking the time to think at this point: they are just throwing money and guarantees at each new problem that pops up without worrying about the consequence. Since no one can imagine a currency collapse, there isn’t the political will to take the painful steps needed to prevent it (reign in fed and let institutions fail). The forces and trends behind the financial collapse are too powerful to stop.
Buy gold, if you can find it.
