The second draft of the securities firm's trading and settlement system stress testing guidelines has been released, increasing the annual tests from at least once to twice.

A reporter has learned that the China Securities Association recently released the second edition of the “Guidelines for Stress Testing of Securities Company Trading and Settlement Systems (Draft for Comments).” The second draft supplements, refines, and adjusts the provisions based on the first edition. One of the core changes in the second draft is the adjustment of testing frequency and trigger mechanisms, requiring securities firms to use a production environment or a test environment with comparable configuration, conducting at least one test annually, and key information infrastructure units to conduct at least two tests annually. This becomes the first clause to propose differentiated testing frequencies for different types of securities firms. The second draft also introduces mandatory requirements that each stress test must cover the basic compliance scenarios outlined in the testing guidelines. When there are significant changes or obvious modifications to the system architecture, securities firms are required to add expanded and enhanced scenarios and recommended supplementary scenario testing based on the system situation.
