The Washington Post reported on Friday morning that Treasury Secretary Timothy Geithner and Chinese Vice Premier Wang Qishan were close to a deal that would permit the Chinese yuan to appreciate by 3 percent this year.  

3%! Woo Hoo! We're REALLY Impressed!

This is wholly inadequate and would do little to resolve the U.S.-China trade imbalance, which was $227 billion in 2009 and 60 percent of the total U.S. trade deficit. The balance was largely oil. 
China’s yuan is likely overvalued by 40 percent, and Beijing accomplishes this by printing yuan and selling those for dollars to augment private transactions. In 2009, those purchases were $450 billion or about 10 percent of its GDP and 28 percent of its exports of goods and services. 
The U.S. trade deficit with China and on oil causes a shortage of demand for U.S. made goods and services and stifles investment in U.S. export industries, which are the most productive and R&D-intensive industries. 
In 2010, the trade deficit with China is reducing U.S. GDP by more than $400 billion or nearly three percent. Unemployment would be falling rapidly and the U.S. economy recovering more rapidly but for the trade deficit with China and Beijing’s currency policies. 
Longer term, China’s currency policies reduce U.S. growth by one percentage point a year. The U.S. economy would likely be $1 trillion larger today, but for the trade deficits with China over the last 10 years. 
A three percent revaluation of its currency will do little to change those numbers. In fact, because of Chinese modernization, the intrinsic value of China’s currency rises each year. Hence, a three percent revaluation over the next year would not even amount to the change in yuan undervaluation. 
As the U.S. trade balance with China grew worse, Beijing could say “see exchange rates don’t matter.” 
Beijing is playing the Obama Administration for fools.
