[from next Monday, four Chinese securities firms in Hong Kong will be listed among the first batch of "dual-counter" market makers. The Hong Kong Exchange will officially launch the "Hong Kong dollar-RMB dual-counter model" and dual-counter market maker mechanism in the Hong Kong stock market on June 19. The first batch of 21 double-counter securities and a list of 9 market makers will be released. Among them, the list of market makers includes four Chinese securities firms in Hong Kong, including Citic Lyon, Guotai Junan International, CICC Hong Kong and Bank of China International. HKEx said that after the launch of the dual-counter model, more dual-counter market makers may be included in the dual-counter model. It is understood that under the dual-counter model, market makers will provide bilateral quotations for the buying and selling of RMB-denominated stocks of the above-mentioned securities, thereby providing liquidity for RMB counters and narrowing the price difference between the two counters.
