Is China's currency undervalued as its export surplus hits record levels?
Core argument: China's manufacturing export surplus stands at roughly 2% of world GDP, described as roughly twice the largest surplus Japan ever ran, while exports surge and domestic demand stalls.
China’s macroeconomics are very different from those obtained before the global financial crisis and, even more so, before the end of its property boom. Exports are surging, but domestic demand has stalled. China's export surplus in manufacturing is now around 2% of world GDP, which is “roughly twice the largest surplus Japan ever ran.” Most importantly, China shows an unexplained negative net income of around $125bn on its net foreign investments. But it should, on reasonable assumptions about the income it earns on its $4tn in net foreign assets, have a surplus of some $100bn. As a result, Brad Setser argues, the renminbi is by now some 30% undervalued. China’s policies look unavoidably threatening to much of the world. If a major trading partner runs huge and persistent trade and current account surpluses, everyone else has to run offsetting deficits. This leads to the shrinkage of sectors specialising in producing tradable goods and services, as well as huge domestic financial deficits.
