I should have also added treasury purchases to the reasons for US dollar strength because of perceived safe haven status. Of course in reality nothing could be further from the truth as the US is the epicentre of this toxic waste created Wallstreet fiasco of epic proportions but old habits die hard but they do die when reality sets in, which it will.
In my view the US has destroyed it's financial credibility with it's derivative excesses, toxic paper creations and greed because no one was minding the farm for the last 12 years or so and has become a debt machine driven and supported by false prophet mathmatic models with mark to model chicanery. Simply unbelievable and will lead to a new world monetary union where the US role is greatly diminished unless guns prevail in which case walls will go up with far raching consequences.
