Approved by the China Securities Regulatory Commission, the Shanghai Stock Exchange, Shenzhen Stock Exchange, and Beijing Stock Exchange have issued a notice to revise the Implementation Rules for Margin Trading. Experts say that this will promote the functionality of margin trading and securities lending business, and better meet the reasonable trading needs of investors. In the revised Implementation Rules for Margin Trading, the minimum margin ratio for investors to purchase securities through margin trading has been reduced from 100% to 80%. This adjustment will be implemented after the market closes on September 8, 2023. It is understood that this adjustment applies to both new opening contracts and stock contracts, and investors do not need to apply the new margin ratio to the balance contract. Securities companies can comprehensively evaluate the credit and performance status of different customers, and reasonably determine the proportion of financing margin for customers. Data shows that as of August 24th, the balance of on-site margin trading and securities lending was 1567.8 billion yuan, and the margin ratio remained at a high level. The overall risk of the business was controllable. The China Securities Regulatory Commission stated that in recent years, the margin trading and securities lending business has been operating steadily, the trading mechanism has been continuously optimized, the compliance risk control level of securities companies has been continuously improved, and investors' rational trading and risk prevention awareness have significantly increased. Yang Delong, Chief Economist of Qianhai Open Source Fund: On the basis of overall controllable leverage risk, the moderate relaxation of financing margin ratio has met the moderate financing needs of some investors, increased the total amount of funds that can enter the market, and is conducive to promoting the function of margin trading and activating existing funds. Margin trading is a credit trading system that mainly refers to investors providing collateral to companies with relevant business qualifications, borrowing funds to buy securities, or borrowing securities and selling them. Simply put, the key to margin trading lies in the word 'financing', which means that investors must provide certain guarantees and pay certain fees, and return the borrowed funds or securities within the agreed period. The China Securities Regulatory Commission reminds investors to continue to adhere to a rational investment philosophy and use margin trading tools reasonably based on their own risk tolerance. The China Securities Regulatory Commission will urge securities companies to effectively strengthen risk management, provide good investor services, and protect the legitimate rights and interests of investors.
