The CBRC requires that trust companies participating in stock index futures business must have a regulatory rating of 3C or above, and those applying for speculation in stock index futures trading should have a regulatory rating of 2C or above, and have been engaged in hedging or arbitrage business for more than one year.
2C is not authoritative yet. Comprehensive rating is a comprehensive evaluation of trust companies, including corporate governance structure, internal control, compliance management, asset management and profitability. The comprehensive rating is not the weighted average of the rating results of the above five factors, but is determined comprehensively after considering the importance of the factors.
