Swedish Firms Show Broad but Uneven Readiness for T+1 Settlement Transition

Key Takeaways

• Finansinspektionen's survey of Swedish market participants finds strong overall readiness for the move to T+1 settlement, with 84-88% of respondents reporting preparedness for the December 2026 and October 2027 deadlines, respectively.
• However, smaller firms lag behind larger institutions, and most companies have not committed to industry-wide testing, raising concerns about operational resilience ahead of the transition.

Deep Dive

This update signals that the Swedish T+1 transition is progressing largely on schedule, but with meaningful gaps that compliance and operations teams must address. FI's survey results show that while larger institutions have already mapped their processes and begun remediation work, smaller companies are only beginning to engage with the requirements. This divergence creates systemic risk, since T+1 settlement depends on every link in the chain—custodians, brokers, and smaller intermediaries alike—functioning correctly and on time.

The core operational challenge identified is the need to submit settlement instructions on the same day a trade is executed, eliminating the current buffer for manual correction of errors. This represents a significant shift from current T+2 practices and requires automation, straight-through processing, and robust exception-handling capabilities. Firms that rely on manual intervention or batch-based processes will face heightened settlement fails risk once the transition takes effect.

Key dates compliance teams should track: initial adjustments are required by December 7, 2026, with full transition to T+1 settlement occurring on October 11, 2027. FI has also indicated it will launch a follow-up survey for non-respondents and conduct dialogue meetings with firms, meaning additional regulatory engagement and potential scrutiny should be expected in the interim period.

A particularly notable risk area is testing. Despite FI and ESMA's emphasis on industry-wide testing to confirm interoperability across systems, most Swedish firms have indicated they do not plan to participate in such testing. This is a red flag for operational risk, as isolated internal testing cannot validate end-to-end settlement chain functionality. Compliance and risk teams should treat this as a priority area, ensuring their firm participates in industry testing initiatives and can demonstrate this to the regulator if queried.

Recommended actions include: (1) benchmarking current T+1 readiness against FI's recommendations and the EU T+1 Industry Committee roadmap; (2) accelerating automation of settlement instruction workflows to meet same-day requirements; (3) committing to and documenting participation in industry-wide testing; (4) engaging proactively with FI surveys and dialogue sessions to avoid being flagged as a laggard; and (5) extending due diligence to smaller counterparties and clients to confirm their readiness, given FI's stated intent to trace weak links through larger CSD relationships.
