Domestic financial instability and foreign reserves accumulation in China

摘要

Using a time series analysis, this paper argues that domestic financial instability, which increases the potential for resident-based capital flight from the domestic currency, provides an incentive for China to hold more foreign reserves in the short run. To measure its domestic financial conditions, we construct a monthly Chinese financial stress index, which is used as a proxy for the possibility of capital flight. The empirical results show that this index is a significant determinant of the movements of China's foreign reserves around its trend and that using M2 as a proxy for domestic financial instability as suggested by previous studies is not a valid strategy for China. It is suggested that greater attention should be given to the role of domestic financial conditions in explaining China's short-run demand for foreign reserves.
