For the past six years, the Chinese government has kept the economy on life support in the form of massively expanded credit creation, government-directed investment into urban and transport infrastructure development and, most important, real estate construction. In the process, local governments, banks and businesses across China have amassed extraordinary levels of debt. Outstanding credit in China is now equivalent to 251 percent of the country's gross domestic product, up from 147 percent in 2008. Local governments alone owe more than $3 trillion. It is unknown -- deliberately so, most likely -- what portion of outstanding debts are nonperforming, but it is likely far higher than the official rate of 1 percent.
