(20)Under Part XII, Division 1 of the SFA, MAS has established a comprehensive regulatory framework to ensure market integrity and prevent insider dealing and market manipulation in relation to securities, units in collective investment schemes and derivatives contracts. This framework prohibits, and authorises MAS to take enforcement action against, practices which could result in distorting the functioning of the markets, such as false trading and market rigging (section 197), bucketing (section 201A), price manipulation (section 201B), employment of fraudulent or deceptive device (section 201), and the dissemination of information about illegal transactions (section 202). Sections 218(2) and 219(2) of the SFA also prohibit insider dealing and the communication of inside information. Under Sections 15 and 33 of the SFA, AEs and RMOs are required to maintain and enforce business rules for the proper regulation and supervision of their members. To help ensure that trading activities are subject to ongoing and effective surveillance, AEs are responsible for ensuring compliance with all applicable regulatory requirements. Accordingly, they are expected to put in place systems, processes and controls to ensure compliance and prevent misconduct. MAS conducts periodic inspections of the surveillance and enforcement functions of AEs to ensure their relevance and effectiveness in detecting trading irregularities. RMOs are also expected to put in place processes and controls to detect potential insider dealing and market manipulation.
