• A Chinese wall is a business term used to describe a virtual barrier erected to block the exchange of information between departments of a company.

  • The wall is not physical, but ethical, designed to prevent the exchange of information that could lead to ethical or legal violations.
  • In the financial industry, the need for such barriers increased with the passage of the Gramm-Leach-Bliley Act of 1999 (GLBA), which repealed federal laws that prohibited firms from any combination of banking, investment, and insurance services.
