Renewed warnings about the bubble in housing prices in China. Earlier warnings came from Krugman, Lardy, John Taylor. This one comes from Nomura economists Zhiwei Zhang and Wendy Chen. Could the government's action to curb rising housing prices not be adequate leading to a financial crisis as early as 2014, is the question posed by Zhang and Chen. They cite the rise of housing prices by 84% from 2001 to 2006, before the financial crisis of 2008 in the U.S., using the Case-Shiller housing price index. One problem- the government statistics may have underestimated the extent of the bubble. China's official index shows housing prices rising 113% in major cities from 2004 to 2012. Zhang and Chen say this is much smaller than the actual rise because it includes older, lower quality housing property. They cite an academic paper that adjusts for this and finds prices jumping by 250% in the period 2004 to 2009. Another problem is that China's housing prices growth slows after government action but then resumes the growth, leaving the risk exposure at the high level as before. Because the local governments are tied up in the housing bubble the problem would hit the banking system. About 14.1% of the outstanding bank loans are to local government financing vehicles, and 6.2% to property developers, according to Nomura economists. The declining potential growth rate in China means there is less room for bad loans to be absorbed by hyper growth levels than in the past. Errors in policy can magnify the risk including loosening monetary policy and exacerbating the bubble at the wrong time. In the absence of errors the risks still remain requiring the sale of public assets to bail out local governments and banks. The argument made by Krugman and other economists has been that China is not immune to the risks of a housing bubble going bad, in any way less than Sweden, the U.S., Spain and other countries, requiring bailouts of banks....
