Category 3
Category 3 MT messages: foreign exchange, money markets and derivatives
Written and maintained by ZagTrader. Last reviewed . How this page is sourced and checked
Category 3 is where treasury back offices confirm the deals their dealers agree: foreign exchange spots, forwards and swaps (MT300), fixed loans and deposits (MT320), call and notice deposits (MT330), currency options (MT305, MT306), forward rate agreements (MT340, MT341) and interest rate and cross currency swaps (MT360, MT361, MT362, MT364, MT365).
Both parties to a deal usually send a confirmation, and the two are compared, by the parties themselves or by a matching service, using a common reference built from both parties’ codes. Unmatched or unconfirmed deals are an operational and regulatory risk, so confirmation matching is one of the first controls a treasury operations team runs every day.
Category 3 was not part of the November 2025 payments migration to ISO 20022 and stays on MT. Settlement of the cash legs uses payment messages such as MT202 or its ISO 20022 equivalent.
