Abstract: In mid 2015, China's stock market experienced abnormal fluctuations. CFFEX has implemented policies such as increasing the transaction fees and margin to restrict index futures trading. This paper explores the policy's influence on the spot market volatility using Difference-in-Difference （DID） model. The results show that for both the CSI 300 index and the CSI 500 index, the policy significantly reduces the volatility of the spot market in the short term. The policy is more effective for stocks with a higher proportion of noise trading.
