The China Financial Futures Exchange (CFFE) announced a series of measures to curb speculation of stock index futures on Wednesday.
The CFFE said it will raise margin requirements on stock index futures from 30 percent to 40 percent of the contract value.
The upper transaction limit on a single product will be reduced to 1,000 shares per day for each investor.
For investors who buy a product and sell it on the same trading day, the CFFE will charge a transaction fee of 0.23 percent of the contract value, up from the current 0.0115 percent.
The CFFE also warned customers to learn regulations carefully before de facto transactions and asked each of them to make a written promise that they will abide by the rules.
The measures will take effect from Sept. 7.
