What Is Chinese Wall?
A Chinese wall (increasingly referred to as an "ethical wall" or "information barrier") is a virtual barrier within a financial institution that restricts the flow of material non-public information between different divisions — particularly between investment banking and research/trading departments. These barriers prevent conflicts of interest and insider trading. For example, an investment bank advising on a merger must prevent its traders from using that knowledge to trade the target company's stock. Chinese walls are mandated by securities regulations and enforced through physical separation of departments, restricted computer access, compliance monitoring, and restricted lists of securities that employees cannot trade. The concept became codified in U.S. law after the Securities Exchange Act and was strengthened by the Global Settlement of 2003, which addressed conflicts between research and investment banking.
