Britain’s Financial Markets Embrace Change: The Journey to T+1 Settlement

uk stock market T+1In a significant move aimed at enhancing the efficiency and competitiveness of its financial markets, Britain is set to accelerate the completion of share transactions, aligning more closely with Wall Street’s pace. The transition to a one-business-day settlement period (T+1) from the current two days marks a pivotal shift in trading operations, promising to modernize the landscape of share trading in the UK. Spearheaded by the Accelerated Settlement Taskforce, this initiative reflects a deliberate and phased strategy to ensure market readiness and system adaptability.

A Gradual Transition Ensuring Market Preparedness

The decision to adopt a phased approach in transitioning to T+1 settlement times is a testament to Britain’s commitment to market stability and participant readiness. Charlie Geffen, chair of the Accelerated Settlement Taskforce, emphasizes the inevitability of the move towards T+1, focusing on the “how and when” rather than “if.” This strategic stance underscores the importance of preparedness in the face of significant operational shifts, ensuring that banks, asset managers, and other market participants have ample time to adjust their systems and processes.

The Role of the Technical Group

A crucial step in facilitating this transition is the formation of a technical group tasked with developing common standards and processes. This collaborative effort aims to harmonize the technical and operational aspects of T+1 settlement across the London Stock Exchange, banks, and asset managers, among others. The establishment of this group is pivotal in ensuring a smooth and coordinated switchover, minimizing potential disruptions and enhancing overall market efficiency.

This foresight allows for adequate budgeting and planning, addressing one of the industry’s key concerns regarding the transition. While some industry officials anticipate the actual switch to T+1 may not occur until 2026, the phased approach allows for flexibility and learning, especially taking into account the upcoming changes in the United States, Canada, and Mexico.

International Coordination and the Path Forward

The move towards T+1 is not unique to Britain; the European Union has also expressed its intention to adopt a similar timeline, highlighting the need for international coordination. Geffen’s reluctance to set a concrete date for the switch in Britain is prudent, allowing for adjustments based on lessons learned from the U.S. transition and ensuring that the necessary coordination is achieved through a mandated approach.


Britain’s strategic decision to move towards a T+1 settlement period signifies a major step forward in aligning with global financial market practices. By adopting a phased and collaborative approach, the UK demonstrates its commitment to ensuring that its financial markets remain competitive, efficient, and responsive to the needs of market participants. This transition not only promises enhanced operational efficiency but also underscores Britain’s position as a forward-thinking financial hub, ready to embrace the challenges and opportunities of the 21st century.
