The new regulation on settlement discipline for securities trading transactions obliges the buyer in a securities transaction to initiate a Buy-in process against the seller should the settlement of a transaction fail after a certain period of time. This requires a neutral third party who acts as Buy-in Agent. The Buy-in Agent service closes this gap and enables market participants to comply with the European regulation that is expected to come into force in February 2022. In addition, the solution provides a high level of standardisation and automation in order to resolve the operational burden which is associated with the new mandatory Buy-in process.
