Fortress CSD is STT’s central securities depository software for capital market institutions that need electronic management and settlement of securities traded on an exchange or over the counter.
The system supports custody, registry, depository and settlement workflows, helping CSDs manage securities operations across multiple asset classes, including bonds, commodities, equities and money market instruments.
Fortress CSD can support straight-through processing, SWIFT messaging, ISO standards, reporting, corporate actions, participant access and integration with third-party systems.
The solution can operate independently or form part of STT’s broader market infrastructure stack, including exchange, trading, clearing and real-time risk management solutions.
