KEY HIGHLIGHTS

  • Inaccurate or outdated SSIs drive 21% of T2S settlement fails, costing firms ~€70M monthly in cash penalties. Discover why resolving static data issues is critical ahead of Europe's October 2027 T+1 deadline.
  • Across Europe’s 32+ CSDs, 67% of firms run separate in-house SSI databases and only 28% are automated. Learn how fragmented settlement data creates severe friction as allocation windows shrink to T+0.
  • With >70% of global settlement moving to T+1 or faster by 2030, manual methods cannot scale. Explore how FMSB standards, ISO 20022 and self-service tools like Citi Direct are automating SSI workflows.

Lack of inventory, be it securities or cash, may be the biggest trigger for settlement fails, but data quality issues, such as inaccurate, missing or outdated Standing Settlement Instructions (SSIs) are a significant factor too. With the deadline for T+1 compliance in Europe just over one year away, time is running out for the industry to get its SSIs into shape.
