I'm beginning to think that Paul Krugman is the only one more obsessed with the Chinese currency value issue than I am (not that I agree with all of his views of the issue, but I do share his interest). As Dan Drezner notes, here is yet another piece by Krugman making the same points he made a couple weeks ago:
Most of the world’s major currencies “float” against one another. That is, their relative values move up or down depending on market forces. ... most nations try to keep the value of their currency in line with long-term economic fundamentals.
China is the great exception. Despite huge trade surpluses and the desire of many investors to buy into this fast-growing economy — forces that should have strengthened the renminbi, China’s currency — Chinese authorities have kept that currency persistently weak. They’ve done this mainly by trading renminbi for dollars, which they have accumulated in vast quantities.
And in recent months China has carried out what amounts to a beggar-thy-neighbor devaluation, keeping the yuan-dollar exchange rate fixed even as the dollar has fallen sharply against other major currencies. This has given Chinese exporters a growing competitive advantage over their rivals, especially producers in other developing countries.
He has said this part before. The new point he makes is this:
What makes China’s currency policy especially problematic is the depressed state of the world economy. Cheap money and fiscal stimulus seem to have averted a second Great Depression. But policy makers haven’t been able to generate enough spending, public or private, to make progress against mass unemployment. And China’s weak-currency policy exacerbates the problem, in effect siphoning much-needed demand away from the rest of the world into the pockets of artificially competitive Chinese exporters.
But why do I say that this problem is about to get much worse? Because for the past year the true scale of the China problem has been masked by temporary factors. Looking forward, we can expect to see both China’s trade surplus and America’s trade deficit surge.
That, at any rate, is the argument made in a new paper by Richard Baldwin and Daria Taglioni of the Graduate Institute, Geneva. As they note, trade imbalances, both China’s surplus and America’s deficit, have recently been much smaller than they were a few years ago. But, they argue, “these global imbalance improvements are mostly illusory — the transitory side effect of the greatest trade collapse the world has ever seen.”
Basically, his view is that it's even worse than we thought, and the Obama administration better do something quick.
