The UK’s transition to T+1 settlement is fast approaching, but industry complacency risks turning a regulatory milestone into a costly operational shock, according to Andrew Douglas, chair of the UK Accelerated Settlement Taskforce.
With a fixed implementation date of October 2027 now effectively locked into law across Europe and the UK, Douglas warned that firms treating T+1 as a narrow compliance exercise are missing a broader strategic shift.
“If you just look at it as compliance, you miss the point,” he said during a fireside chat at FundsTech 2026, arguing that the move represents a “gateway” to wider digital transformation across financial services.
The shift from T+2 to T+1 settlement will compress post-trade processes dramatically, requiring firms to complete the same operational workload in a fraction of the time. “You will have to do 100% of the work you do today in 20% of the time,” Douglas said, emphasising that automation is no longer optional but essential for survival in a digital-first market.
Lessons from the US transition in 2024 underline the risks of inaction. Firms that failed to prepare saw back-office staffing costs rise by as much as 16–18% as they scrambled to meet new requirements manually. In an industry where margins are measured in basis points, such cost inflation can be highly disruptive.
Regulators are also stepping up scrutiny. The Financial Conduct Authority is expected to take a more “intrusive” supervisory approach, requiring firms to demonstrate clear plans for compliance. Failure to do so risks not only financial penalties for late settlement but also reputational damage and increased regulatory attention.
Douglas stressed that responsibility ultimately lies with individual firms. While the taskforce has outlined clear recommendations, including the need for automation and improved settlement processes, “it’s your job to reverse engineer that into your back office and identify the gaps,” he said.
Operational readiness will depend on the entire transaction chain functioning efficiently. A single weak counterparty can disrupt settlement, prompting firms to reassess trading relationships and favour partners with higher levels of automation. Initiatives such as an industry “readiness register” aim to improve transparency and help firms identify compliant counterparties.
Encouragingly, much of the market is already close to meeting tighter deadlines, with around 86–87% of settlement instructions currently submitted on time. However, Douglas urged firms to focus on the remaining failures, often linked to specific instruments or counterparties, as a starting point for improvement.
With testing windows opening and timelines tightening, the message is clear: preparation must begin now. Firms that delay risk higher costs, strained relationships and regulatory scrutiny—while those that act early may gain a competitive edge in an increasingly automated marketplace.
“Don’t wait until the last minute,” Douglas said. “You can prevent the fire before it starts.”
