Following the implementation of negative interest rates by the euro zone, Switzerland, Denmark and Sweden, the Japan's central bank announced its adoption of negative interest rate on January 29, 2016, it is possible that more nations will follow suit. ANBOUND's chief researcher, Chen Gong is of the view that the worldwide negative interest rate environment might pose a significant risk to the banking system. Since China does not have close ties with the international financial market, in the event the negative interest rate triggers global financial crisis, as soon as the risk starts to spread, China should absolutely consider the possibility of shutting down its financial system. This is equivalent to a temporary measure of "cutting off electricity supply".
