The difficulty here is that the evidence is patchy and not always reliable. According to one estimate, since the post-crisis stimulus of 2008, total public and private debt in China has risen to more than 200 per cent of GDP. Figures collated by the World Bank show that credit to the private sector rose from 104 per cent of GDP in 2008 to 130 per cent in 2010, before declining marginally in 2011. The evidence suggests that 2012 has seen a further sharp increase.
The problem is not merely the rapid rise in credit as a means to spurring investment and growth.
