Economists Who Believe the Fed's Holdings of $3 Trillion in Assets Affects Interest Rates Must Believe China's Holdings of $4 Trillion in Reserves Affects Exchange Rates

May 15, 2015

The Washington Post told readers that China’s government is no longer acting to keep the value of the dollar up against its currency:

“Economists say that over the past several years, China’s currency has risen to a fair value, no longer providing Chinese exporters with a leg up on U.S. businesses.”

After citing several economists who support the claim that the currency is at or near a market value, it then reports that it’s trade surplus is within a normal range.

“Nick Lardy, a Peterson economist specializing in China, says that in 2014 China’s trade surplus dropped to 2.2 percent of gross domestic product, a level considered an indicator of fair exchange rates. At their peak in 2007, China’s exports amounted to 10 percent of GDP, he said.”

There are several points worth noting. First, while it appears that China has largely stopped its large-scale purchases of foreign exchange (mostly dollars), its central bank now holds close to $4 trillion in foreign exchange. This is at least twice what would be expected for a country with an economy of China’s size.

It is widely believed by economists that the Fed’s holding of $3 trillion of assets is holding interest rates down in the United States. The idea is that by holding this stock of government bonds and mortgage backed securities, it is keeping their prices higher than they would be if investors had to hold this stock of assets. (Higher bond prices mean lower interest rates.) If we accept the view that holding a large stock of bonds affects their price, then it must follow that the decision of China’s bank to hold a large stock of foreign reserves raises their price relative to a situation where investors held them. This would mean that China’s central bank is continuing to prop up the value of the dollar against its currency, even if it is not actively buying dollars.

The point about a trade surplus of 2.2 percent of GDP being normal is also misleading. This would be a reasonable figure for a slow growing rich country like the United States. Economists usually expect fast growing developing countries like China to be running trade deficits. The idea is that capital earns a better return in a fast growing country. This pushes up the value of its currency.

Remember the billions of stories in the media last fall about how the dollar was rising because the U.S. economy was so strong? (It was growing at a bit more than a 2.0 percent annual rate.) That should be happening with China, given the huge difference between its growth rate and the growth rates in the U.S., Europe, and Japan. The rise in the value of China’s currency would make its goods and services less competitive internationally, shifting its trade surplus to a deficit. The fact that this is not happening is explained by the actions of China’s central bank to keep its currency from rising.
