Well, most USD watchers focus on the Euro because it’s such a heavily weighted part of the index. IMHO what we should be watching is the Chinese Yuan and maybe to a lesser extent the Ruble. The Yuan is at its’ highest levels vs. the USD since March. Santelli has mentioned it twice now in the last two days.
So, we watch the Yuan and maybe Germany to see if they stay in the EU. Could be awhile though.
