The only effective record of Systematic Internaliser (SI) services, essential to determine the current MIFID II status of a trading counterparty.
The SI Registry provides this information by allowing SIs to register the details of the financial products for which they are providing SI services, in a single centralised register, that is updated daily. The SI Registry is a collaboration between the SmartStream RDS and a group of Approved Publication Arrangements (APAs). The initiative is open to all APAs and SIs with over 120 SIs currently sharing their status. The service is fully Brexit ready and able to support both the EU and UK trade reporting regimes.
