Firewall

The legal barrier between banking and broker/dealer operations within a financial institution created to prevent the exchange of inside information.

Chinese Wall

Informal; the imposed lack of communication between the investment banking and brokerage services of a financial institution. The Chinese wall exists in order to prevent brokers and investment bankers working for the same company from deliberately or accidentally sharing inside information that could lead to illegal insider trading. The Chinese wall protects both the financial institution at large and the individual investment bankers and brokers.
