Jim Grant: Gold is the play off a confusing Fed

"I think gold will really be interesting when people stop asking what the Fed is going to do, and begin asking, who is the Fed and what can they know?" said Grant, who's the founder of Grant's Interest Rate Observer, a bimonthly newsletter.

"We are the prisoners of a very dubious set of pseudo-scientific pretensions that are part of the people who manage our monetary affairs," he added.
