DTCC says June 30 is double settlement day after faulty trades

On June 30, 2026, the Depository Trust & Clearing Corporation (DTCC) reported that the day marked a significant increase in settlement activity due to a higher volume of faulty trades that required reprocessing. This surge in activity led to a dual settlement workload, with both corrections and new transactions needing timely resolution to meet regulatory deadlines. The incident highlights the challenges associated with accelerated settlement cycles, particularly as markets across the European Union, United Kingdom, and Switzerland prepare for the transition to T+1 settlement by October 2027.

The EU T+1 Industry Committee has emphasized the importance of automation and standardization in post-trade processes to reduce the likelihood of such issues. The committee’s High-Level Roadmap, published in June 2025, outlines key timing requirements for allocations, confirmations, and settlement instructions, all of which must be completed within tight deadlines to ensure smooth operations. The UK AST implementation plan similarly recommends electronic processing of allocations and confirmations by 23:59 UK time on the trade date.

DTCC’s ALERT® platform, which supports the electronic exchange of Standard Settlement Instructions (SSIs), has been instrumental in improving straight-through processing and reducing settlement fails. The platform’s compliance with FMSB standards ensures that firms can meet the heightened demands of T+1 settlement. As the industry moves toward a more automated and harmonized post-trade environment, incidents like the one on June 30 underscore the need for continued investment in operational resilience and technological readiness.
