In 12 months’ time, securities markets across the EU, UK, Switzerland and Liechtenstein will move to a T+1 settlement cycle. Naturally, the industry is focused on implementation and readiness, as any significant change to market structure deserves careful preparation.
Ultimately, however, this transition phase is temporary. By 2028, firms will have settled into a new operating rhythm, and attention will move elsewhere. The more urgent question now is what T+1 tells us about how market participants are preparing for an uncertain future.
Clearer view
One way we identify emerging trends in post-trade FX is by examining how firms use our services.
Following the US transition to T+1, demand for the automation of operational processes increased. In CLSTradeMonitor, our post-trade monitoring and reporting tool, use of API connectivity increased among the 20,000 funds and 60 asset managers using the service.
The reason is that shorter settlement cycles leave firms with less time to discover and resolve problems. Market participants wanted a clearer view into what was happening between trade execution and settlement so they could respond before issues became settlement risks.
We have also seen more interest in the service among European firms preparing for T+1. German asset manager MEAG provides one example. Before adopting CLSTradeMonitor, the firm relied on daily reports from multiple custodians to reconcile FX trades across more than 130 funds. Information came from multiple sources and required significant manual review. Unmatched trades were sometimes identified only shortly before custodian cut-off times, reducing the time available to resolve issues before settlement.
By introducing a consolidated view of matched and unmatched trades, MEAG reduced the volume of positions requiring reconciliation and gained earlier visibility into potential exceptions. As MEAG put it: “Near real-time visibility of unmatched trades helps us identify risks earlier, giving us more time to act before custodian cutoff times and easing last-minute liquidity pressures. With the move to T+1 fast approaching, achieving greater operational and execution efficiency has become essential.”
T+1 is the catalyst, not the destination
However, the CLSTradeMonitor case study is not simply about one product or one aspect of post-trade efficiency. Rather, it illustrates one way in which the shift to T+1 is prompting firms to reassess elements of the post-trade process that may become increasingly difficult to sustain as settlement windows compress.
Trade monitoring and visibility into settlement are part of a broader operational chain. Exception management, reconciliation, funding and communication between counterparties and custodians can all come under pressure when the available time shrinks.
The mistake would be to view October 2027 as the finish line. That perspective is understandable while firms rightly focus on executing a successful transition. However, T+1 is better understood as the beginning of a wider evolution in how post-trade operations are designed and operated. Markets must be prepared for changes extending beyond settlement cycles. Global financial markets are transforming in ways that would have seemed unlikely just a few years ago.
US exchanges are exploring longer trading hours. Digital assets and tokenized securities have revived discussions around near-instant and atomic settlement. Across markets, participants expect faster access to information, execution and reporting. In short, market infrastructure is moving toward shorter timelines and fewer buffers.
Viewed in that context, T+1 starts to look less like a destination and more like one step in a broader evolution of market structure.
Beyond 2027
Unlike North America, Europe is not contending with the same degree of time-zone friction that affected investors funding US securities transactions from Europe and Asia. Compared to the shift to T+1 for securities settlement in the US1, there is less concern about the impact of Europe’s T+1 transition.
There will, of course, still be operational challenges. The alignment of securities and FX processes remains important. Firms need to understand how custodian cutoff times interact with compressed settlement windows. Funding and prefunding processes require careful consideration where transactions fall outside normal settlement arrangements.
In time, firms will address these challenges as they adapt their processes and establish new operating norms.
By investing in stronger exception management, cleaner post-trade processes and greater visibility of settlement status, firms are preparing for more than the October 2027 transition. They are preparing for markets that leave less time to identify problems, tolerate less operational friction and demand greater coordination across counterparties and service providers.
