UK Firms Must Act Now to Prepare for T+1 Settlement Deadline

The United Kingdom is set to transition to a T+1 securities settlement cycle, reducing the current two-day process to just one. This significant change will take effect on October 11, 2027, marking the UK’s entry into the global T+1 framework. Financial firms across the UK must now initiate preparations to ensure a smooth transition, as this shift will impact all market participants.

Understanding the Implications of T+1

The move to T+1 is more than just a technical adjustment; it is a strategic reform aligned with the UK government’s Mansion House agenda. This initiative aims to enhance investment, improve efficiency, and bolster the UK’s market competitiveness. The change is also a crucial step towards broader digitalisation efforts. Faster settlement will mitigate counterparty and liquidity risks, liberate capital, and foster greater market efficiency and resilience.

To reap these benefits, firms must shift their focus from planning to execution. The UK Accelerated Settlement Taskforce (AST) recently published an implementation plan, prompting many firms to begin their preparations. Research from the first half of 2023 indicates that over two-thirds of firms have already started this process, a promising sign for the industry. Nevertheless, much work remains to be done as the October 2027 deadline approaches.

Essential Steps for Firms

Market participants must establish their T+1 capabilities by the end of this year. The AST recommends that firms should:

• Review the AST’s Implementation Plan published in February.
• Assess the impact of T+1 on their operations, as each firm’s technological and operational circumstances differ.
• Develop a comprehensive plan to achieve T+1 readiness by 2026, ideally through automation, as suggested by AST guidelines.
• Secure the necessary budget to implement this plan.

These foundational actions are crucial for ensuring a well-structured and secure transition that maintains market resilience. Additionally, firms should prepare for an increased agenda of changes as digitalisation progresses.

The recent migration to T+1 in North America has highlighted the tangible benefits of accelerated settlement, particularly the crucial role of automation. Transitioning to T+1 will eliminate more than 80 percent of the time currently spent correcting settlement errors and recalling stock loans. Relying on manual processes will not suffice in this new environment; automation across the entire post-trade chain is essential.

Investing in automation now will help firms manage costs effectively and avoid complications later. Some companies are already recognizing the competitive edge that comes with automation, choosing to collaborate exclusively with other automated firms, which may lead to broader market-wide efficiencies by the deadline.

The UK Accelerated Settlement Taskforce is collaborating closely with the European Industry Committee, led by Giovanni Sabatini, to ensure a seamless transition. By aligning the timelines and standards across the UK, EU, and Switzerland, the transition can be coordinated, minimizing disruptions for firms operating across borders. The goal is to make the mandated T+1 trading day as uneventful as possible, marking a successful shift for the market.

As the deadline draws nearer, it is imperative for firms to act decisively. The time to prepare is now, and the groundwork laid will be instrumental in achieving a smooth transition to T+1.
