As the CNY depreciates, just a quick note for perspective.

As the Chinese economy continues to slow (at least apparently), a lot of attention has centered on the Yuan’s course; the depreciation against the dollar shouldn’t obscure the fact that the CNY remains fairly strong on a trade-weighted basis.

Since the series is plotted in log terms, one can read off the difference in values at two times as a percentage change. Over the past year, the real CNY has risen from 0.13 to 0.27, implying a 14% appreciation against China’s trading partners’ currencies.
