One of the interesting things about the presidential debate tonight was the prominence of China. Governor Romney repeated his insistence that he would declare China a currency manipulator “on day one”. (I am surprised he didn’t mention the “yellow peril”.) If his criterion is forex intervention, he should be prepared to declare many other countries manipulators as well.

Even the Peterson Institute for International Economics, which has been adamant historically, recently estimated a 3% undervaluation.
