T+1 readiness by stabilizing the most critical operational handover points
On 11 October 2027, the European Union’s capital markets will transition to the T+1 securities settlement cycle. This shift is far more than a regulatory milestone. It represents a fundamental transformation of post-trade operations, requiring tighter coordination, higher data quality, and significantly greater reliance on automation.
T+1 success is driven by critical operational handover points
The timing and quality of trade matching, instruction handling, and workflow steps determine overall settlement performance.
No full platform replacement is needed
T+1 readiness can be achieved by introducing targeted capabilities that stabilize critical workflows within the existing system landscape.
Standardized, message-based connectivity is essential
Efficient, automated, and standardized communication between market participants is crucial. Manual processes are not scalable in a T+1 environment.
T+1’s impact: a paradigm shift in operations
T+1 forces a fundamental shift in operations. All should get from reactive operations to real-time control. In a T+1 environment manual fixes don’t fit into the timeline, data gaps turn into immediate settlement risk and delays upstream break execution downstream.
Phone calls, faxes, or spreadsheet-sharing for matching only in exception handling. Direct integration ensures automated instruction pathways run instantly.
Under T+1, error matching must happen on T-day immediately or risk fail penalties.
Increasing headcount is not scalable. Operations must process daily transaction spikes smoothly without manual confirmation handoffs.
Instead of reacting to fail messages at the end of the settlement window, systems must flag mismatching instruction data SSIs at execution time.
How to prepare for the T+1 transition
Financial institutions should review their entire trade-to-settlement process, especially areas such as data management, allocations, confirmations, settlement instructions, status tracking, reconciliation, and exception handling.
Manual or delayed processes
Identify exactly where manual or delayed processes exist in your current trade-to-settlement flow.
Settlement failure risks
Locate which data or communication issues could lead directly to settlement failures.
Affected systems & partners
Pinpoint which systems and counterparties are affected by the compressed T+1 timeline.
Required upgrades & automation
Determine where automation, standardization, or system enhancements are required.
Getting Ready for T+1: Key Actions to Take
Follow these structured steps to ensure operational resilience and compliance before the transition.
Conduct a T+1 readiness assessment
This helps identify which processes, data, channels, and control points require attention.
Determine where the following are needed:
Align with your core system provider or Dorsum
Explore whether and how your core system can support the required changes.
Prepare a priority roadmap for 2026–2027
Formulate a timeline-driven operational strategy to align system readiness with regulatory requirements.
Verify technology and DORA compliance
Ensure all messaging interfaces are secure, resilient, and fully compliant with digital operational resilience standards.
Get ready for T+1 with Dorsum
"The trusted partner who understands your unique path and mitigates risks with technical capabilities."
Following the initial assessment, it becomes possible to clearly distinguish which topics can be handled within the existing back-office system, where it is worth integrating ClavisNXT-based T+1 capabilities, and which areas require alignment or optimization within your own processes, data structure, or operational framework.
We Stabilize Critical Handover Points, Not the Entire Platform
You do not need to replace your entire legacy post-trade platform to achieve T+1 compliance. Dorsum introduces targeted, message-driven capabilities that seamlessly wrap around your existing system landscape.
Trade Matching & Confirmation Automation
Automate validation, client allocations, and matching checks immediately post-execution.
Settlement Instruction Lifecycle Control
Track instructions in real-time from initiation to settlement confirmation, eliminating blind spots.
Data Standardisation & SSI Management
Transition SSIs and reference data into automated, standard messaging formats (SWIFT, ISO).
Exception Handling & Operational Control
Replace individual spreadsheets with a centralized, dashboard-driven exception tracking framework.
Integration & Messaging Layer
Connect legacy core architectures via REST APIs, SFTP, and SWIFT message translation modules.
Operational Outcomes
Fewer Late Settlements
Avoid expensive Central Securities Depositories Regulation (CSDR) cash penalties and buy-in procedures.
Reduced Manual Intervention
Shift operational staff from typing manual trade entries to supervising centralized dashboard exceptions.
Proactive Risk Controls
Detect data gaps or late trade matching results before they become settlement-level failure flags.
Flexible Message Integration
Connect smoothly with counterparties using REST APIs, SFTP, and SWIFT translation layers.
