The effect of stimulus policy on lending behavior and bank risk: Evidence from the Chinese banking sector

Considering China's stimulus policy in 2008 as a quasi-natural experiment, our study attempts to provide evidence to understand how expansionary monetary policy is likely to influence bank risk-taking in emerging markets, specifically in China. Using data on Chinese counties from 2006 to 2011, we theoretically discuss and empirically observe a positive relationship between the stimulus policy and bank risk-taking, as measured by nonperforming loans. Such a nexus stems from the negative effect of the stimulus policy on banks' lending standards and the positive effect on banks' credit support to small and medium sized enterprises. In addition, our study is enriched by estimating the moderating effects of bank capitalization based on the "risk-shifting" effect and "search for yield" effect caused by the stimulus policy. Specifically, we find important differences across banking groups, such that small and medium-sized banks with low capitalization increase their exposure to risk, while large state-owned banks with high capitalization notably reduce their risk tolerance. The results of this study may help to characterize monetary policy and macro prudential regulation, especially for emerging economies.
