Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
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. 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.
