As the U.S. moves to T+1 settlement on May 28, 2024, our latest report, Hitting 90% Affirmation by 9:00 PM ET on Trade Date: The Key to T+1 Success, unveils crucial strategies for a seamless transition. Under today’s T+2 timeline, approximately 90% of all trades are affirmed by 11:30 AM ET on T+1, the current affirmation cutoff. Under T+1, to maintain existing levels of settlement efficiency, the industry should affirm at least 90% of all trades by the 9:00 PM ET cutoff on trade date.

Key takeaways:

  • The move to a T+1 settlement cycle may require market participant firms to adapt operations to ensure they have adequate time to allocate, confirm and affirm trades by 9:00 PM ET on trade date (the T+1 DTCC affirmation cutoff).
  • Based on trades currently affirmed on T+1 that settle under the current T+2 timeline, DTCC recommends the industry affirm 90% of all trades by 9:00 PM on trade date. Doing so will maintain current levels of market efficiency and lower the chances for a potential increase in trade fails.
  • Unfortunately, DTCC data shows that only 69% of all trades were affirmed by 9:00 PM on trade date in December of 2023. To support the move to T+1, the industry must focus on affirming trades earlier.
  • Institutional trades settled bilaterally through DTC could achieve higher on-time affirmation rates by:
    • Ensuring market participants understand best practices of using a TradeSuite ID omnibus account number.
    • Encouraging investment managers to obtain their own TradeSuite ID number.
    • Examining the pros and cons of first, having custodian counterparties affirm, second, managing self-affirming or third, leveraging a central matching solution with auto affirmation capabilities such as CTM’s Match to Instruct (M2i) workflow.
