估计你什么都没搞请，逻辑不对啊。

Buy MBS, is to increase credit creation. Itself is inflationary. It has nothing to do with shorting gold.

shorting gold is tiring to give a shot to the weakening dollar, thereby to fortify the confidence on dollar. 

All boils down that fed knows that QE is dollar negative, the only way to save it is to creat a phantom impression that dollar was still the "safe haven".

if dollar.was still the safe haven, why all the people here buy cabbage houses?
