Will the Phoenix Fly Again?

What kind of phenomenon is a banker's oath? The oath is a warranty added to a promise, and has a complex nature and history that is discussed. Recent research on promising is presented that indicates that there may be a desired effect on both oath taker and on the audience, even if an oath is performed reluctantly or insincerely. Based on a comparison with the oath of office, it is argued that a banker's oath is not just a professional oath sworn to peers, but rather a political oath whereby one swears to the nation. Furthermore, the oath's long history indicates possible strengths and problems with the introduction of a banker's oath. It is concluded that the moral nature of an oath has to be taken into consideration, and that it is not just a tool to try and create trust.
