SSI Management: ALERT®
The Gold Standard for SSIs
Accurate Standing Settlement Instructions (SSIs) are vital for fast, compliant trade matching and settlement. But outdated, incomplete or inaccurate SSI data continues to be a leading cause of trade exceptions and settlement failure.
With over 17 million multi-asset SSIs, ALERT streamlines the management and sharing of SSIs. In ALERT, SSIs are securely stored, centrally managed and automatically shared with counterparties, enabling firms to reduce trade fails, support T+1 readiness and align with industry-standard practices.
