CISI UAE Financial Rules and Regulations recognize the concept of a Chinese wall, which permits employees in one part of a regulated business to withhold certain information from employees in other parts. This internal information barrier is designed to prevent conflicts of interest and insider trading by restricting the flow of sensitive or non-public information between departments. By implementing Chinese walls, firms ensure compliance with legal and regulatory requirements, uphold market integrity, and protect client interests. While audit requests and privacy concerns are valid, the primary regulatory rationale for withholding information internally is to maintain effective Chinese walls.
