Moody's senior analyst based in Beijing, Yvonne Zhang, says China's National Audit Office's estimate of the banks loans as part of China's total local government debt of 10.7 trillion yuan ($1.65 trillion) is understated. The Audit Office estimated bank loans to be 8.5 trillion yuan. Moody's says this is understated by 3.5 trillion yuan or about $540 billion. Moody's sees the delinquency ratio of these loans between 50 and 75%. With these figures it sees 8-12% of bank loans in China's banking system as non-performing loans.
