Paul Krugman: Chinese New Year

It’s the season when pundits traditionally make predictions about the year ahead. Mine concerns international economics: I predict that 2010 will be the year of China. And not in a good way.

Actually, the biggest problems with China involve climate change. But today I want to focus on currency policy.

China has become a major financial and trade power. But it doesn’t act like other big economies. Instead, it follows a mercantilist policy, keeping its trade surplus artificially high. And in today’s depressed world, that policy is, to put it bluntly, predatory.

Here’s how it works: Unlike the dollar, the euro or the yen, whose values fluctuate freely, China’s currency is pegged by official policy at about 6.8 yuan to the dollar. At this exchange rate, Chinese manufacturing has a large cost advantage over its rivals, leading to huge trade surpluses.
