Weathering financial crisis in China: the role of global market integration

We test the hypothesis that the integration of China into the global financial system, as a consequence of domestic market reforms, reduced the effectiveness of intervention efforts during the stock market crises. Using an event study methodology in tandem with the DCC GARCH and Markov Regime Switching models, we investigate whether the interventions were able to address the decline in market returns and volatility during the 2008 and 2015 stock market collapses. Results show that the 2015 measures were ineffective compared to the 2008 ones and that the increasing global integration of the Chinese market played a significant role in their failure. This study is the first of its kind and the results have important implications for policymakers, given the vital position of China in the international economy.
