China’s Trade Surplus

The August numbers are in. From MarketWatch:

China posted a wider-than-expected trade surplus in August as imports unexpectedly contracted from the year-ago period, suggesting anemic domestic demand, according to data released Monday.

Exports exceeded imports by $26.7 billion during the month, beating expectations for a $17.2 billion surplus in a Dow Jones Newswires survey of economists.

Monthly exports rose 2.7% from a year earlier, indicating relatively weak overseas demand, with the gain missing a 3% projection from a Reuters poll of economists.

But imports surprised by dropping 2.6% from August 2011, failing expectations for a 3.4% increase from the Dow Jones Newswires survey and a 3.5% forecast gain in the Reuters survey.

The evolution of the trade balance and the Chinese real exchange rate is shown in Figure 1.

This is more apparent when trade balance is normalized by GDP, as in Figure 2.

I remember a year ago having discussions with other China analysts over the issue of the sustainability of this downswing in the Chinese current account balance. Note that reduction in the surplus preceded the global slowdown.

Back in April, the IMF released a working paper forwarding the explanations for the revision in the Chinese CA outlook, which was quite substantial, as shown in Figure 3:

Figure 3: Source: Ahuja et al. (2012).From Ahuja, Ashvin, Nigel Chalk, Malhar Nabar, Papa N’Diaye, and Nathan Porter, 2012, “An End to China’s Imbalances?” IMF Working Paper 12100:

It’s important to note that the forecasts are conditional: “these forecasts assume a constant real effective exchange rate, the [April 2012] World Economic Outlook projections for global demand, and a path of steady, medium-term fiscal consolidation in China.” The assumption of constant real effective exchange rate (for purposes of consistency with other forecasts in the WEO) explains in part why the CA begins to improve again. As I’ve noted elsewhere, continued real appreciation is a necessary part of adjustment over the longer term.

The authors conclude:

… the decline in China’s external surplus has been impressive and should be welcomed. However, this adjustment has largely been the result of very high levels of investment, a weak global environment, and a pace of increase of commodity prices that outstrips the rising price of Chinese manufactured goods. While all three of these factors are likely to continue to put downward pressure on the external imbalance, this does not represent the “rebalancing” in China advocated by the IMF over the past several years. In particular, the available official data which cover the period through the end of 2010 do not yet indicate that the shift in the external imbalance is due to consumption rising as a share of GDP or national savings falling.

Just as the current account surprised on the downside, it might surpise on the upside going forward. From yesterday’s NYT:

Many Chinese economic indicators already show a slowdown this spring, with fixed-asset investment growing at its weakest pace in May since 2001. The annual growth rate for industrial production has edged below 10 percent, while electricity generation was up only 3.2 percent in May from a year earlier and up only 1.5 percent in April.

The question is whether the actual slowdown is even worse. Skewed government data would help explain why prices for commodities like oil, coal and copper fell heavily this spring even though official Chinese statistics show a more modest deceleration in economic activity.

So to the extent a step up in investment might have contributed to the current account decline, a big down step in private investment will result in a CA reversal, unless offset by government investment (and or consumption or private consumption) (see the saving-investment approach to the current account, discussed here). However, an increase in government investment will only exacerbate the longer term challenges of rebalancing the Chinese economy toward more consumption.[2]

    Last time I checked, the appreciation of China's exchange rate was even more striking if calculated on a unit labor cost basis. Is that still the case?
