ISO 15022 is an ISO standard for securities messaging used in transactions between financial institutions. Participants in the financial industry need a common representation of the financial transactions they perform and this standard defines general message schema, which in turn are used by organizations to define messages in a complete and unambiguous way.[1] This results in efficiency, lower costs, and the avoidance of errors. Prior to standardization in this area, there were overlapping standards, or ad hoc approaches where there was a functional gap and no standard.
