378) Should China devalue its currency? - Gary Becker

Should China revalue its currency?
By Gary S. Becker
China Daily, February 24, 2010

US President Barack Obama has apparently complained to President Hu Jintao about the yuan's low value and urged him to revaluate it substantially.

Two of the most important and closely related economic issues today are the value of the yuan and the huge assets accumulated by China, mainly in the form of United States Treasury bills and other US government assets.

China's central bank had the yuan's value fixed at a little over 8 per US dollar during the 1990s and until 2005. It then allowed the yuan to rise gradually to less than 7 a dollar until 2008, when it again fixed the rate of exchange at about 6.9 yuan per dollar. This exchange rate is considerably above a free market rate that would be determined in a regime of flexible exchange rates. So there is no doubt that China is intentionally holding the value of its currency below the rate that would equate supply and demand.

The value of the greenback has fallen substantially against other currencies since May 2009. Since the yuan is tied to the dollar it's value, too, has declined in the same ratio: 16 percent against the euro, 34 percent against the Australian dollar, 25 percent against the Korean won, and 10 percent against the Japanese yen. This substantial devaluation of the yuan has made many countries angry with China's policy of pegging it to the US dollar.

The US and other countries are worried that the undervaluation of the yuan increases the demand for Chinese exports and reduces China's demand for imports from countries like the US because China keeps the dollar and the currencies of other countries artificially expensive compared to its currency.

The US and other countries hope that greater demand from China for their exports, resulting from a higher value of the yuan, will help them resume sizable economic growth as they recover from severe recession. Their governments especially want to reduce the high levels of unemployment.

Indeed, in good part due to the low value of its currency, China has run substantial surpluses in its current trade account because it imports fewer goods and services than it exports. As a result, it has accumulated enormous reserves of assets in foreign currencies, especially US government assets denominated in dollars. At the end of last year, China had an incredible more than $2 trillion in foreign currency reserves, which included US Treasury bills. This is by far the largest reserve in the world and its ratio to China's GDP is huge: a quarter of about $8 trillion (purchasing power parity adjusted).

I doubt the wisdom of the US for complaining against China's currency policy and of China for its response. On the whole, I believe most Americans benefit rather than being hurt by China's long-standing policy of keeping the yuan at an artificially low exchange value. The policy makes the goods imported from China, such as clothes, furniture and small electronic devices, much cheaper than they would have been if China revaluated its currency substantially. The main beneficiaries of China's current policy are poor and lower middle class Americans and people in other countries who buy made-in-China goods at remarkably cheap prices in stores such as Wal-Mart that cater to cost-conscious families.

US companies that would like to export more to China have indeed been hurt by China's currency policy. They employ fewer people than their capacity and thus contribute to the high rate of unemployment in the US. But I believe the benefits to American consumers far outweigh any losses in jobs, especially because the US economy continues its recovery.

Since the opposite effects hold for China, I cannot justify the country's policies from the viewpoint of its interests. Its consumers and importers are hurt because the government has kept the cost of foreign goods artificially high for them. Their exporters gain, but as in the US, that gain is likely to be considerably smaller than the negative effects on the well-being of the average Chinese family.

I have reached a similar conclusion on China's excessive reserves. The US has little to complain if China wants to hold such high levels of low interest-bearing US government assets in exchange for selling inexpensive goods to the US and other countries. China's willingness to save so much reduces the need for the Americans and others to save more. But are not differences in savings rates part of the specialization that global markets encourage? It is difficult to understand why China is doing this because it is giving away goods made with hard work and capital for paper assets that carry little returns.

One common answer is that China hopes to increase its influence over international economic and geo-political policies by holding so many foreign assets. Yet it seems to me just the opposite is true - that China's huge levels of foreign assets put it more at the mercy of American and other countries' policies. China can threaten to sell large numbers of the US Treasury bills and other US assets it holds, but what will it buy instead? Presumably, it would buy European Union or Japanese government bills and bonds. That will put a little upward pressure on the interest rates of other governments. But to a considerable extent, the main effect in our integrated world capital market is that sellers to China of euro and yen-denominated assets would then hold the US Treasuries sold by China.

On the other hand, the US can threaten to inflate some of the real value of its dollar-denominated assets - not an empty threat because of the large US government fiscal deficits and the sizable growth in US bank excess reserves. Inflation would lower the exchange value of the dollar, and also of the yuan as long as China keeps it tied to the greenback. That would further increase the current account surpluses of China, and thereby induce it to hold more US and other foreign assets, which is not a very attractive scenario for Beijing.

So my conclusion is that the US in its own interest should not urge China to revaluate its currency - countries such as India have a much greater potential to gain from such a revaluation. On the other hand, I see very little sense at this stage of China's development for Beijing to maintain a very low value of its currency and accumulate large quantities of reserves. Paradoxically, presidents Obama and Hu should have been arguing each other's position on these economic issues.

  1. This is a great article. I have been researching the Chinese decision to allow the Yuan to float freely. It is nice to see a different perspective to this issue. Most people seem to think that this is good for the US and for the balancing of the world economic system. I don't understand the topic well enough to really have an educated opinion. It does seem that a stronger Yuan would lead to less imports from China into the US (or a rise in the cost of the imports). It seems that this would also create a larger demand in the Chinese market for high-end goods manufactured in the US. Which in turn would lead to more job opportunities for middle class Americans. Are we seeing the balancing out or re-structuring of the international economic system from the original shock from the expansion of Free trade in the Clinton years? I am not too sure about all of the details relating to how Free Trade has impacted the rise of China. But, I am always wanting to know more. Thank you for your article!
