China's Currency Move Eases Tension

But doing more to raise the yuan's value and rebalance trade could create thousands of American jobs.



China’s announced change in exchange rate policy is just a start, though it does mark an important step in the direction of a more balanced economic relationship with the United States. Even if the same 18% appreciation achieved from 2005 to 2008 -- before the global economic downturn prompted the Chinese government to put a halt to the policy -- were duplicated in the next three years, the imbalance would remain. And that’s both damaging and dangerous.

China’s undervalued yuan clearly provides the country with a huge competitive advantage. In a 2007 survey of estimates, all but one of 18 studies concluded that the yuan was undervalued vis-à-vis the U.S. dollar, with an average undervaluation of 40%. More recently, the conventional wisdom puts the yuan’s undervaluation today at 24% to 30%.

Regarding merchandise trade, America ran a $231-billion deficit with China over the past year, accounting for 42% of the $547-billion U.S. total. But the impact of China’s exchange rate policies stretches beyond that, because some of China’s neighbors manage their exchange rates to preserve their competitiveness against the Asian giant’s exports in third markets. So their currencies are also undervalued relative to the American greenback. U.S. trade with Taiwan, Vietnam, Malaysia and China together accounts for fully half of America’s trade deficit.

The undervaluation isn’t, of course, entirely a bad thing. After all, cheap goods from China lower living costs here, stretching the value of the dollar. But there are reasons China’s undervalued currency is especially problematic right now.

Cheap goods aren’t a big priority for America at present. Thanks to the resource slack created by the Great Recession, inflation is already low, at around 1%, and further declines wouldn’t be especially welcome.

And the trade deficit with China directly translates into lost output and jobs. When unemployment was under 5%, that wasn’t a pressing issue. Now that the jobless rate is closer to 10%, it’s a political and economic albatross. Given a rule of thumb that says each $1 billion of net exports creates 7,000 jobs, trimming the Chinese trade deficit in half would create roughly 800,000 desperately needed jobs.

This brings us to the second aspect of the unbalanced economic relationship with China: investment. In the absence of Chinese intervention, the Asian country’s trade surplus with the U.S. would naturally lift the value of the yuan as U.S. demand for yuan-based merchandise vastly exceeded Chinese demand for dollar-based merchandise. Since that’s antithetical to China’s export-based economic growth strategy, Beijing limits the yuan’s appreciation by recycling its trade dollars back into U.S.-denominated assets, especially Treasury securities. This, too, isn’t altogether bad; it helps keep our interest rates low and buoys the sluggish U.S. economy.

U.S. dependence on large, persistent investment flows from China is scary, however. Any abrupt cessation of Chinese investment (if not offset by larger inflows from elsewhere) would drive up U.S. interest rates, presenting a menacing economic risk. Just as Greece had to scramble to appease foreign investors losing their confidence, so, too, might the U.S. become beholden to China if it quit the market for U.S. assets.

Fortunately, the risk isn’t entirely one-sided. China owns more U.S. securities than any other foreign investor, and it has an enormous pile of foreign exchange reserves to show for it. The precise value of dollar based assets in this stash isn’t known for sure, but it’s easily around $2 trillion. So China has a huge stake in the American economy, and any fiscal problems of ours are major concerns of theirs. That’s why, for example, the People’s Bank of China was among the first phone calls then-Treasury Secretary Henry Paulson made when nationalizing Fannie Mae and Freddie Mac. In addition, any appreciation of the yuan also translates into direct losses on China’s portfolio of U.S.-denominated assets. A 20% appreciation translates into a loss of $400 billion, for example.

The good news is that China has nothing to gain and a lot to lose in this complex and unhealthy relationship -- a relationship sometimes described as MAD, an acronym borrowed from the nuclear doctrine of mutually assured destruction. The blowback from an “attack” by one on the other would be severe enough to act as a deterrent.
