Three Flawed Arguments for a Stable Yuan

♠ Posted by Emmanuel in at 2/23/2010 12:17:00 AM
Steven Dunaway at the Council of Foreign Relations has an interesting essay on why those who argue for a stable yuan--especially PRC officialdom--are incorrect. While I am general agreement with his arguments, the real question for me that remains largely unanswered is how to get China to move on the matter of currency. Without further ado, here are the arguments he shoots down:

I. The first old argument making a comeback is that a stable yuan is not only good for China, but is good for the rest of the world. The roots of this argument go back to the Asian financial crisis of 1997-98. At that time, China was persuaded to keep its exchange rate fixed against the U.S. dollar when its currency was facing downward pressure to prevent setting off a round of competitive devaluations among the crisis-stricken countries in the region. While at the time this was a very important policy decision by the Chinese authorities, any competitive disadvantage that China may have suffered was quickly more than offset in the period after the crisis by the rapid growth in productivity in China relative to its competitors. Nevertheless, despite a burgeoning trade surplus, China continued to defend a pegged exchange rate until July 2005 (when the rate was revalued slightly and allowed to appreciate gradually until August 2008, at which time the rate was effectively repegged to the U.S. dollar) as being in the best interest of China and the rest of the world, just as it had been in 1997-98.

China's actions in 1997-98 are being invoked by officials in Beijing as justification for China's decision during the current economic and financial crisis to maintain a stable exchange rate against the U.S. dollar. It is argued that this policy helped to support China's growth during the recession and that it is good for the rest of the world because strong growth in China's economy makes a major contribution to recovery in the world economy.

There is truth to this claim from a narrow statistical point of view. As the second or third largest economy in the world, if China grows faster, then that would, of course, raise the average rate of growth for the world economy. But that does not mean China's growth is adding measurably to the growth of other countries. That impact depends on how much growth in China's demand is contributing to stimulating growth in other countries. The reality is that China with a large trade surplus sells substantially more to the rest of the world than it purchases, and therefore, it continues to subtract significantly from net world demand. Thus, the rest of the world as a whole is not benefitting much from China's strong growth.

Some countries (particularly those in Asia and commodity producers) may be benefitting, and the decline in China's trade surplus in 2009 means it took less away from net world demand than in previous years. Nevertheless, China's contribution to the rest of the world's growth has not been much, and it will diminish in 2010 and the years beyond as China's trade surplus is expected to start rising again.

II. Another old argument still making the rounds is that even if the yuan were allowed to appreciate significantly, it would not materially change the pattern of imbalances among the world's major economies because it is not the root of the problem. Even with a higher value for the yuan, China would continue to be the world's leading exporter because it has a major competitive advantage in manufacturing. Manufacturing in the developed countries would not recover. Therefore, the argument concludes, changing China's exchange rate cannot be expected to make a major contribution to boosting the net exports of developed countries.

For instance, some analysts argue that even if China's currency were allowed to appreciate such that China's current account surplus would decline by 4 percent of its GDP annually and return to a level more in line with the country's long-term fundamental saving and investment balance, this would directly contribute only about a half percentage point to annual growth in the developed countries. Such a boost to these countries' economies is characterized as being small and not critical to addressing global imbalances.

However, when the developed countries are looking at prospects for annual growth of 1-2 percent, an extra half percentage point boost to growth that would come from China permitting its exchange rate to adjust is no small matter. In addition, this half percentage point addition to growth from foreign demand would further stimulate economic activity in the developed countries so that, ultimately, the impact of such a change in China's exchange rate policy would be even greater. Also, the boost to developed country growth would permanently raise the level of incomes and employment in the developed countries.

In a world economy looking for new sources of stimulus to spur demand growth (and developed countries as a rule having little scope to make further use of fiscal policy), the old argument is clearly wrong. A change in China's exchange rate policy is a critical element in the world economy's recovery.

III. Finally, there is the grand old argument that the Chinese authorities do not respond well to external pressure for policy change. Changing exchange rate policy in China is a political decision made at the highest level of government. Accordingly, China's leaders do not want to be seen as bowing in the face of foreign pressure. This is said to be particularly true at the moment because relations between China and some of the developed countries, especially the United States, have become increasingly tense. In these circumstances, the Chinese authorities could choose to cling to the current fixed exchange rate policy to project strength. The suggestion from this argument is that the rest of the world should ease pressure on China, and a change in China's exchange rate will come at a more appropriate time.

The reality is, however, that without pressure being exerted to encourage a change in its exchange rate policy, China will have no reason to move. And when patience grows thin and pressure rises again, this same argument will be trucked out once more to try to further postpone policy adjustment.

It is on the last point that Dunaway justifies the heat being placed on Chian by President Obama. Still, I find the "reverse psychology" argument interesting. That is, don't bug China on currency and it will eventually revalue since it won't be seen as "giving in" to foreigners.
