Navigating the UK’s T+1 Transition: How Market Participants Can Prepare.

The UK’s move to a T+1 settlement cycle by October 2027 marks one of the most significant overhauls in post-trade infrastructure in decades. This shift—reducing the settlement window from two days to one—promises to enhance market efficiency and align the UK with global counterparts like the US and Canada. However, the transition also introduces complex operational, regulatory, and strategic challenges for asset managers, custodians, and trading venues. For firms seeking guidance, SecFin Solutions, a London-based consultancy founded by industry veteran Glenn Handley, offers tailored strategies to navigate this transformation. Drawing on decades of front-office expertise, SecFin provides actionable insights for optimising collateral, automating workflows, and ensuring compliance in the new T+1 era.

What T+1 Means for UK Market Participants

Regulatory Timeline and Structural Shifts
The UK’s Accelerated Settlement Taskforce (AST) has mandated T+1 implementation by October 2027, requiring legislative amendments to the Central Securities Depositories Regulation (CSDR). This applies to equities and bonds traded on UK venues and settled via CREST, while exempting repos and securities lending transactions. Firms must adopt automated trade affirmation systems, submit settlement instructions by 6:00 AM on T+1, and align with the Financial Markets Standard Board’s (FMSB) guidelines for instruction sharing.

The compressed timeline intensifies pressure on cross-border trades. For example, Asian asset managers trading UK equities will face a 3-hour window to finalise FX conversions—a process previously allowing 14.5 hours under T+2. As Glenn Handley, CEO of SecFin Solutions, notes: *“Firms that cling to manual processes risk settlement fails and regulatory penalties. Automation isn’t optional anymore—it’s existential.”

Operational Challenges: Automation, Liquidity, and Collateral

The Race to Automate
T+1’s 50% reduction in settlement time forces firms to overhaul legacy systems. Manual trade matching, batch processing, and paper-based confirmations will become untenable. Euroclear’s CREST system will extend operating hours to 9:00 PM, but firms must still reconcile discrepancies in near-real time.

SecFin Solutions advises clients to adopt ISO 20022 messaging standards and AI-driven exception management tools. Their consultants specialise in integrating distributed ledger technology (DLT) for real-time settlement tracking—a critical upgrade for firms juggling multi-jurisdictional trades.

Collateral and Liquidity Pressures
While repos remain under T+2, T+1’s tighter equity settlement cycle will ripple into collateral markets. Demand for high-quality liquid assets (HQLA) like UK gilts is expected to rise, straining balance sheets. Handley predicts *“sponsored repo volumes will surge as firms seek off-balance-sheet solutions to manage liquidity costs”.

SecFin’s collateral optimisation strategies help institutions leverage non-traditional assets, such as green bonds, while adhering to Basel III capital requirements. Their team also designs stress-testing frameworks to simulate quarter-end liquidity crunches—a vulnerability highlighted by recent SOFR rate spikes.

Strategic Shifts for Buy-Side and Sell-Side Firms

Asset Managers: Integrating Front and Middle Offices
Buy-side firms must synchronise portfolio management with post-trade operations. Pre-trade funding checks and AI-driven fail prediction are becoming essential. SecFin’s *“action this day”* methodology ensures exceptions are resolved within hours, not days—a practice Handley honed during his tenure at HSBC and Barclays.

Custodians and Prime Brokers: Redefining Client Services
Custodians face mounting pressure to offer real-time settlement analytics and API-driven instruction portals. Meanwhile, prime brokers must expand intraday credit lines to accommodate clients’ compressed funding cycles. SecFin’s workshops train operations teams on CREST’s upcoming API enhancements, ensuring seamless transitions ahead of 2027.
