When I hear the U.S. senate cry about how the allegedly undervalued yuan hurts the economy, I can't help myself from thinking that money would be better spent on a gigantic hamster wheel to power The Big Apple during peaks instead of having the worsts of the lunatic fringe argue over something about which they don't know anything. As the proverb states, "No attention is paid to him who is always complaining", so it is with the U.S. senate. They can blow their horns as much as they want, but no one will lend his ear. In fact, they can't be serious when they say the yuan should revalue by as much as 20% overnight by letting it float. That would spell disaster for the Chinese economy. It would not only open the floodgates and unleash huge flows of hot money onto the economy—the NYSE has by far the largest market capitalization in the world and it alone would be more than enough to completely engulf the Shanghai Stock Exchange, but many state-owned banks would go belly up as they own lots of U.S. treasuries. Moreover, singling out the exchange rate as the culprit is simply rubbish, especially since the economy was so poorly managed. Many policy mistakes were made. Reckless government spendings, unsustainable monetary policies, financial deregulations, restrictions on exports, to name a few. The main factor contributing to the U.S. current account deficit is the discrepancy between investment and savings. According to this view, domestic savings are not enough to meet the demand of capital, which is satisfied instead by offshore capital. Consequently, currency appreciation is offset by the outflow of capital hindering trade adjustment. Although this does not explain the chronic trade deficits with China, it does suggest that unless there is an increase in domestic savings the U.S. trade deficit with China would barely budge even if it were to revalue the yuan. The experience of Japan proves that currency appreciation does little to solve the problem. After the Plaza Accord, the yen exchange rate skyrocketed up to 1/145 relative to the dollar from 1/238; yet the U.S. trade deficit continued unabated. Now, there are other ways out of this. I can only think of two in the immediate present. One would be to increase wages; the other, strengthen the social safety net. I have also heard some criticisms on the interest rate, which is allegedly kept at a low rate to stifle consumer spending. Obviously, a little pat would be enough to shrug off this one. State-owned banks are heavily burdened with bad assets on their balance sheets, which threateningly creak under their weights. Raising interest rates would cause these balance sheets to buckle on their own weights. I can't wait to hear the next diatribe coming from The Congress, on Muslim extremism.
