A free lunch

An old article by Tyler Cowen:

CONTRARY to popular opinion, China may be good for our trade balance. American consumers seem determined to spend money, and Chinese businessmen have made the bill cheaper.

It is not the case that China is simply draining the United States of money. Most of the growth in Chinese exports to the United States has come from switching manufacturing and assembly from other, more expensive, Asian countries.

...C. Fred Bergsten, director of the Center for International Economics, has been calling for a revaluation of the yuan for years, in the hope that a more valuable currency will make Chinese exports more expensive.

The belief is that if the dollar has less value in China, Americans will spend less on Chinese products to offset the prices they pay per item. But even if the numbers work out so that the flow of dollars to China diminishes, American consumers will pay higher prices and see fewer goods from China. Yuan revaluation is unlikely to benefit the United States, even if it does lower its trade deficit.

The trade effects of a revaluation of the yuan are unlikely to be large, in part because many Chinese exporters specialize in assembly. China sends out money buying components like semiconductors and turns them into finished goods, thereby running a trade deficit with East Asia. A new and higher value for the yuan would largely be a wash for these activities. With a stronger currency, China would have a harder time selling its electronic goods, but this would be offset by its greater purchasing power over the semiconductors. It would not do much damage to the Chinese competitive position.

The Chinese keep the yuan low, relative to the dollar, by buying up United States Treasury securities; as of early 2006, the Chinese central bank held up to $470 billion in Treasury securities. This huge accumulation of relatively low-yielding assets is the investment strategy of risk-averse bureaucrats, but it may bring longer-term benefits. Those assets can someday be sold or otherwise transferred to underdiversified Chinese financial institutions. The accumulation gives the Chinese a stake in American prosperity and signals that the Chinese are committed to long-term participation in the global economy. On the American side, the Treasury market is more liquid and the budget deficit can be financed at lower cost.

The yuan should not, as matters stand, float freely with free capital movements. Large quantities of Chinese savings, currently restricted to the domestic currency, would probably flee the country, worsening the serious solvency problems at Chinese banks. The Chinese must first clean up their banking system before they can have free capital markets. Contrary to the conventional wisdom, a market-determined value for the yuan might well be lower than today's exchange rate, not higher.

To the United States, the primary gains from yuan revaluation would come from the increased spending by Chinese consumers on American exports. But the Chinese are, and should be, extremely cautious. In addition to saving about 50 percent of their incomes, they are spending most of the rest on local basics, like food, cheap cars or education. Health care is a probable growth sector. China is still a poor country, and its potential to drive American export success is modest for the foreseeable future.

...

The climb of the Chinese economy out of Communism and into prosperity has brought the world, and the United States, a free lunch. Consumer goods of many kinds are cheaper and the Chinese are likely to generate many scientific and technical innovations. Steering the value of the Chinese currency -- from Washington -- is unlikely to increase those gains. The United States should not be spending its international political capital on yuan revaluation, which is at best a nonevent.

In fact, as Lawrence Lindsey wrote some time ago:

America, however, benefits from this arrangement. The Chinese clearly undervalue their exchange rate. This means American consumers are able to buy goods at an artificially low price, making them winners. In order to maintain this arrangement, the People's Bank of China must buy excess dollars, and has accumulated nearly $1 trillion of reserves. Since it has no domestic use for them, it turns around and lends them back to America in our Treasury, corporate and housing loan markets. This means that both Treasury borrowing costs and mortgage interest rates are lower than they otherwise would be. American homeowners and taxpayers are winners as a result.
