Roundtable Report: Is Your Firm Ready for T+1?

Read the post roundtable report on the Tplus1 settlement readiness challenges facing the UK, EU and Swiss transition to accelerated settlement.

The move to T+1 settlement is no longer a future policy debate. It is now an operational reality that every market participant needs to prepare for. With the UK, EU and Switzerland targeting transition in October 2027, firms are entering a decisive period in which plans must become tested, evidenced and ready to operate under compressed timelines.

Our latest T+1 Industry Readiness Challenges Roundtable Report captures the key themes from an Edinburgh discussion organised by the SIO in association with  ISITC Europe, with participants from the Investment Association, Euroclear, asset management, custody, middle-office outsourcing, securities financing, technology and market infrastructure. The discussion was clear: no firm can be ready in isolation. Successful implementation will depend on the preparedness of custodians, fund administrators, brokers, counterparties, technology providers and market infrastructures across the full settlement ecosystem.

The report explores the most pressing readiness challenges, including automation, FX constraints, fund settlement cycle decisions, static data quality, securities financing transactions, external provider readiness and the need for robust testing. It also highlights the growing importance of documented decision-making as regulators move from broad engagement to evidence-based supervision.

• Operational readiness: how firms are moving from planning to practical execution.
• Automation and data quality: why manual processes, fragmented data and SSI issues need urgent attention.
• Provider and market interdependencies: the importance of custodian, fund administrator, broker and infrastructure readiness.
• FX and funding pressures: the potential impact of mismatched settlement cycles and compressed cut-off times.
• Testing and regulatory evidence: why firms must be able to demonstrate readiness, not simply assert it.

For firms still relying on manual touchpoints, fragmented data or late-stage exception management, Tplus1 represents a major operational challenge. For firms that act early, it is also an opportunity to strengthen resilience, improve straight-through processing and build greater confidence across clients, providers and internal stakeholders.

Read the full report to understand where the industry stands today, what practical gaps remain, and the actions firms should prioritise now to avoid being left behind as the T+1 deadline approaches.
