I believe the dollar is being viewed as the safe haven currency for now - off but I suppose it's all relative in currency. And any thought that some deal might actually work will bring investors out of the dollar and into more higher risk currencies. The move started on friday but there were several reports as to central bank's interventions in the market then. Anyway if they dollar gets weaker I think it would be a good sign for the equity markets as well as a negative for gold.
