About the Effort

All T+1 implementation activities have been completed according to plan. We are now operating in a T+1 settlement cycle.

It has been an enormous undertaking, with financial market participants from all over the globe taking part in preparations to ensure a smooth transition. Please review the helpful resources below should you need additional guidance.

  • DTCC’s T+1 Conversion Guide. This comprehensive guide details the T+1 conversion process, along with changes that are now effective.
  • The SIFMA Command Center continues to provide conversion status information, transparency into the activity of other participants, and serves as a forum for issue identification and socialization. The Command Center’s support will be most active during the conversion period, from Friday, May 24 through Friday, May 31.
  • T+1 Tabletops: Preparing for Unplanned Events- DTCC conducted a series of tabletop exercises with a diverse cross-section of clients (including sell-side, buy-side and custodians) to assess the impacts of hypothetical outage scenarios in a T+1 settlement environment. See our summary of findings.
