What is an MT300 swift?

Answer 1

It is a foreign exchange confirmation message. Swift sends system to system messages to tell other systems that something needs to be done. Once a confirmation document has been created an MT 300 will be sent to a counterparties system to tell them that the confirmation has been created and that they need to create /send a confirmation from their system in order to match the fields/information associated with a trade. However this is all dependant on whether the counterparties bank has access to the SWIFT network, if they don't then normal paper/e-mail/fax etc confirmations maybe sent out which don't require a SWIFT to be sent.

SWIFT messages are set out very much like xml i.e <customer id> but instead uses uniform field names like :16r, which I believe is used to deal with different names for fields in different systems.
