Brad Setser, partner to the better known Nouriel Roubini, notes that the hot money flow into China, to take advantage of an appreciating renminbi, is now moving into a sharp reversal.
The trade surplus should have produced a $115 billion increase in China’s foreign assets. FDI inflows and interest income should combine to produce another $30-40 billion. The fall in the reserve requirement should have added another $50-55 billion (if not more) to China’s reserves. Sum it up and China’s reserves would have increased by about $200 billion in the absence of hot money flows. Instead they went up by about $50 billion. That implies that money is now flowing out of China as fast as it flowed in during the first part of 2008.
