The Securities and Exchange Commission (SEC) will implement a T+1 settlement cycle, shortening the settlement period from 2 business days to one business day, aiming to address market volatility and reduce credit and settlement risk. Most firms' current back-office operations cannot handle this change due to challenges such as manual processes being under pressure, batch data processing not being feasible, and existing systems having limitations in handling large volumes of trade data. To prepare for T+1, firms should automate manual processes, replace batch processes with real-time event-based processing, and leverage MongoDB's developer data platform to accelerate development and improve operational efficiency. The use of an operational trade store (ODS) can help consolidate transaction data in real-time, while MongoDB's integration capabilities enable the development of AI/ML models to manage trade settlement risk failure, ultimately driving efficiency across the securities market ecosystem.
