Simply a full court press being put on from the terrorists in Washington and New York on the dollar. Talk is cheap (Paulson, bernanke and Bush) and I can't point to one fundamental that supports a higher dollar so the dollar will fall again soon enough. I'm sure the dollar shorts are chomping at the bit for another round of profit and certainly the gold longs on the sdielines will welcome the chance to get back in. Sinclair has time and again warned about this volatility in the gold/currency market and he has certainly been right to date. He also said that after the third retest that gold will not be coming back anytime soon and this should qualify. The hard part is getting used to timelines that used to be weeks now done in days.
If I was a betting man I would wager something very bad like another bank failure is coming this way soon and they know it ergo the attempt to talk the dollar higher so when it falls they have a chance to catch it before it breaks it's all time low and really causes a crisis.
