Trade Matching & Confirmation

Trade Matching

The process of trade matching is intended to ensure that transactions, once input into the security settlement system (SSS) at a CSD or ICSD, do not fail to settle because of instruction mismatches.

It is not recommended that counterparties rely purely on trade matching at the SSS for verification of the terms of transactions, as this usually reduces the available time to correct mistakes or resolve disagreement. This in turn may lead to an unexpected build-up of risk.

Once a transaction negotiation concludes, counterparties should promptly verify the terms of the transaction, through trade confirmation and response, prior to input to respective security settlement systems. This procedure will mitigate the risk of trade mismatches and avoid trades being set up with economic differences.

It is recommended that a market vendor is utilised for such trade matching, and that the counterparties to the trade send files to the vendor for comparison at least every 15 minutes, thus allowing pre-matching to occur as soon as possible. The data sent to the vendor should contain all relevant fields for comparison, including the SSIs such that they can also be compared prior to the CSD/ICSD. See IBP-153 for more information on contract compare.


Confirmation is the process of providing a complete record of the commercial terms of a transaction and settlement instructions to the other party. The provision of a Confirmation allows the recipient to cross-check the sender's record of the terms of a transaction against the recipient's own records. Confirmations can also be used during the life of a transaction to verify changes. Counterparties should clarify prior to undertaking any transactions if they intend to provide confirmations, in what timeframe, and any expectations they have in relation to confirmations, of the other counterparty. If counterparties agree not to use confirmations, it is strongly encouraged that a robust Trade Matching and post-trade Contract Compare process is in place between the parties in order to mitigate risk.

New Loan Booking


To support SFTR reporting, it is recommended that both parties to a transaction book a new loan within one hour of its negotiation. See Execution Timestamp (Field 2.12) and Execution Timestamp (Voice Trades) Booking Practices (IBP-296)

SSI Confirmation


Market participants should confirm each transaction with their counterpart, and that confirmation should include SSI.

Note that a confirmation is required within CSDR Chapter III Article 6(2) Regulation (EU) No 909/2014 and although that part of the regulation does not specifically mention SSI, the ISLA Survey 2018 noted SSI communication as one of the largest causes of settlement fails.

In support of this practice, use of a vendor solution is recommended to enable pre-settlement matching of both matching fields and SSI. (IBP-290)
