1. Treasury controls.
A confirmation is a document through which a market participant notifies its counterparties or customers of the details of a trade/transaction and, typically, allows them time to affirm or question the trade/transaction.
The issue and matching of confirmations is one of the key controls in treasury dealing activity.
Increasingly confirmations are being transmitted and matched by electronic means, but the same rules, relating to the separation of the dealing function from the confirmation function, still apply.
