Global Bank has Code of Conduct for Staff Members and a separate Code of Conduct for Executive Directors. Their purpose is to outline basic principles of professional ethics expected from international civil servants, and is intended to provide guidance to Global Bank personnel to avoid situations of real or apparent conflict between their private interests and their public duties. They elucidate and supplement the relevant provisions of the Agreement Establishing Global Bank ("Global Bank Agreement"), the Staff Rules and Regulations, and other relevant legal instruments.

The Codes of Conduct do not set out to define every possible situation that may confront Global Bank personnel nor are they intended to be exhaustive or all inclusive. Global Bank personnel are expected to use their own good judgments or seek appropriate advice form the Integrity Vice Presidency Unit, or Office of the General Counsel (OGC), the Legal Vice Presidency Unit
