Yuan Control

We're all familiar with the lip service given to an increasing Yuan by the Chinese government, but are they finally getting serious? The Chinese government has announced another rate increase on top of their recent efforts to tighten lending restrictions. The end(?) of the US rate hike cycle along with increasing Chinese rates should help boost the Yuan - key word being should. To illustrate how adept China remains at controlling the exchange rate, here is their track record compared to the USD/Yen exchange rate over the past year:
Not going anywhere other than 1.8% a year.

I think we can also deduce the "basket" of currencies China is using to measure the Yuan against by this chart - the US Dollar and a basket of currencies that are pegged to the dollar.
