Brad De Long on Asian Trade Surpluses (Project Syndicate)

Professor of economics Brad DeLong at UC Berkeley has an insightful analysis of the situation Asian economies face vis-a-vis the West:

"...As for Asia's governments, with China in the lead, the US remains the importer of last resort. The key to their development strategy is to put migrants from the countryside to work making exports destined for the US market. They doubt that an alternative development strategy based on boosting domestic demand would succeed. Thus, the real values of their currencies must be kept low relative to the dollar, which means that their reserves now invested in the US must continue to grow.

Someday, of course, this will come to an end. Perhaps Asian real currency values will rise sharply as a result of a burst of inflation in Asia. Perhaps the dollar will collapse and there will be a burst of inflation in the US as the Federal Reserve Board decides that temporarily abandoning its price-level peg is a lesser evil than the unemployment fallout that will result from a dollar collapse and interest rate spike.

A government that buys political risk insurance by placing an ever-growing stock of reserve assets in dollar securities guards against some dangers. But it is exposed to other risks, especially if it confines its investments to that slice of the asset pool, US Treasury and high-grade corporate bonds, that US politicians are comfortable having foreigners own. Nominal bonds are not well hedged against inflation and, over the long run, assets that are claims to cash without effective control are highly vulnerable to financial vultures. Prudent foreign government and private investors would find some way to diversify.

"But how? Buying other countries' bonds would mean abandoning the goal of keeping real currency values low against the dollar. Buying up whole enterprises triggers angry speeches in the US Congress. What are needed are intermediary organizations that will grant a measure of control to foreigners, allow diversification across a wider range of US-located assets, and yet still appear 100 percent American to US politicians...(Source: Taipei Times, Brad DeLong Blog, Project Syndicate version not up yet)
