The Making of China’s Trade Deficit

BEIJING – China registered a monthly trade deficit of $7.2 billion in March 2010, its first since April 2004. And yet, at around the same time, the United States Congress issued its loudest call ever to classify China as an exchange-rate manipulator, accusing Chinese leaders of maintaining the renminbi’s peg to the dollar in order to guarantee a permanent bilateral trade surplus.

China’s March trade deficit indicates, first of all, that it is incorrect to claim that Chinese economic growth depends mainly on exports. Exports are an important part of the Chinese economy, and any global market fluctuation or external shock will certainly have an impact on overall growth. But, like any other large economy, China’s economy is driven by domestic consumption and investment.

Indeed, China’s exports fell by 16% year on year in 2009, owing to the global financial crisis and recession. Nevertheless, annual GDP grew by 8.7%, thanks to 16.9% growth in consumption (measured by gross sale of consumer goods) and a 33.3% surge in fixed-investment demand.

Moreover, although China’s “trade dependency” is now reckoned to be 70% of GDP, that figure is greatly distorted by the fact that Chinese exports require massive imports of materials and parts. The net value added of total Chinese foreign trade accounts for only about 15% of GDP.

Thus, net exports contributed 10.8% to China’s overall GDP growth rate, or only about 1.1 percentage point of 9% growth in 2008. Compare that figure to Germany, where net exports accounted for 64% of growth in 2008. Similarly, the figure was 33% in Japan, 28.6% in Korea, and 20% in the Philippines. Clearly, China is nothing special in this regard.

To be sure, China’s domestic consumption is not as high as it should be, standing at 49% of GDP in 2008, with household consumption accounting for only 35%. Such figures have led many observers to believe that overall domestic demand must be low, leaving China dependent on external markets for growth.

But domestic demand, which determines imports, consists not only of consumption, but also of fixed-asset investment. Indeed, rapid growth in investment may translate into high import growth and trade deficits.

That is exactly what is happening in China now. Some people may argue that investment growth without consumption growth will result in overcapacity and eventually lead to recession. Perhaps. But we need to remind ourselves that housing investment accounts for about 30% of China’s total fixed investment, with much of the rest directed toward infrastructure – that is, long-term, durable public infrastructure investments– including subways, railways, highways, urban public facilities, and the national water system.

Moreover, one can easily imagine that import demand would soar further if the US and the European Union lifted their bans on exports of high-tech products to China. In that case, the trade deficit recorded in March could be at least 40% higher.

The renminbi’s exchange rate, then, is really a secondary factor in China’s external account. Put another way, the global imbalance could be corrected more efficiently by addressing other, more fundamental factors. The fundamental factors underlying the US external imbalance are large fiscal deficits and low household savings, owing to excessive financial leverage. The fundamental factors on the Chinese side are high corporate and household savings, together with some distortion of resource/utility prices.

Indeed, the current situation indicates that a significant adjustment in exchange rates may not be needed at all in order to redress global imbalances. If that is true, and China shouldn’t worry about the renminbi’s exchange rate, should it worry about its economy overheating? After all, its previous trade deficits in the era of reform – such as in 1992-1996 and 2003-2004 – all occurred at times of overheating.

But there are differences between now and those earlier periods. For example, when rapid investment growth in 2004 led to overheating, world markets were booming. At that time, both domestic investment and exports required immediate tightening. Today, by contrast, although domestic investment is growing very strongly, external demand has not recovered to its previous levels.

The result is the March trade deficit, caused mainly by exceptionally high annual import growth (65%) coupled with relatively low export growth, which reached a nominally impressive 24% only because of the sharp decline recorded in the base period. Such a single-factor situation is easier to deal with than the double-factor situation of 2004, and because the high investment demand has been mainly stimulus-related this time, policymakers can handle it in a more timely fashion if they perceive a problem.

That said, the ratio of capital formation does require careful monitoring. The last time China saw such high growth in domestic investment, the savings rate was not as high as it is now. The problem currently is that a trade deficit has emerged at a time when the national saving rate is as high as 51%. That means that investment is extremely high – and that, despite the high share of infrastructure investment, there is an urgent need to manage the potential risks.
