On 28 May 2024 the settlement cycle for most U.S. broker-dealer transactions shortens to T+1 under SEC Release No. 34-96930. Market participants must complete allocations, confirmations, and affirmations by the end of trade date and update operations to support faster funding, securities lending, and collateral flows.

Compliance milestones

  • Same-day affirmation. Investment advisers and broker-dealers must complete allocations, confirmations, and affirmations as soon as technologically practicable and no later than T (end of trade date).
  • Written policies. Investment advisers must adopt procedures ensuring timely completion of post-trade processes; broker-dealers must document arrangements with counterparties.
  • Recordkeeping. Maintain records demonstrating compliance with Rule 15c6-2 requirements and exception handling.

What to prioritize

  • Technology upgrades. Automate trade matching, allocation, and affirmation workflows, integrating with DTCC ITP platforms and custodian interfaces.
  • Funding and liquidity. Adjust treasury processes, securities lending, and collateral management to reflect shortened settlement windows.
  • Cross-border coordination. Align foreign exchange and securities settlement in markets still operating on T+2 to mitigate fails.

Source material

This brief guides trading, operations, and treasury teams through T+1 readiness, spanning workflow automation, policy updates, and exception management.

Rule Overview

The Securities and Exchange Commission's T+1 settlement rule took effect on May 28, 2024, reducing the standard settlement cycle for most broker-dealer securities transactions from two business days (T+2) to one business day (T+1). This is the most significant change to US securities settlement since the transition from T+3 to T+2 in 2017.

The accelerated settlement cycle reduces counterparty and market risk by decreasing the time between trade execution and final settlement. Shorter settlement windows reduce exposure to market volatility and counterparty default during the settlement period, enhancing overall market stability and investor protection.

Affected Transactions

The T+1 requirement applies to transactions in equities, corporate bonds, unit investment trusts, and securities allocated in firm commitment offerings. Exchange-traded funds and most other securities traded on US exchanges fall within the rule's scope. Certain transactions including government securities and options remain subject to different settlement timeframes.

Cross-border transactions present particular complexity, as international markets maintain different settlement cycles. Market participants with global operations must coordinate settlement processes across jurisdictions with varying requirements and timeframes.

Operational Implications

Compressed settlement timelines require significant operational adjustments across the securities industry. Trade allocation, confirmation, and affirmation processes must complete more quickly to support same-day matching and settlement instruction submission. Automation investments help market participants meet accelerated processing requirements.

Foreign exchange transactions supporting cross-border settlements require earlier initiation to ensure currency availability for settlement. Organizations must coordinate FX processes with securities settlement workflows, potentially requiring earlier trading cutoff times or pre-funding arrangements.

Technology and Process Changes

Market participants have invested significantly in technology upgrades supporting T+1 compliance. Automation of trade matching, exception processing, and settlement instruction generation reduces manual intervention and processing time. Straight-through processing capabilities enable same-day completion of post-trade activities.

Integration between front-office, middle-office, and back-office systems supports compressed timelines. Real-time data sharing and automated workflows reduce delays associated with manual handoffs and batch processing cycles. Investment in technology infrastructure positions firms for continued market structure evolution.

Risk Management Considerations

Accelerated settlement reduces overall settlement risk but compresses the time available for exception resolution. Organizations must improve exception management capabilities to identify and resolve issues within tighter timeframes. Escalation procedures and contingency arrangements address situations where standard processing cannot complete within required timelines.

Liquidity management becomes more critical as settlement obligations arise more quickly following trade execution. Organizations must maintain appropriate funding arrangements and collateral management processes to meet accelerated settlement requirements. Cash management improvement helps ensure settlement readiness.

Regulatory Compliance

Market participants must show compliance with T+1 requirements through appropriate policies, procedures, and controls. Documentation should address trade processing workflows, exception management procedures, and escalation protocols. Regular testing validates operational readiness and identifies potential improvement areas.

Coordination with custodians, clearing firms, and other service providers ensures end-to-end settlement chain readiness. Service level agreements should address T+1 processing requirements and performance metrics. Ongoing monitoring tracks settlement performance and identifies emerging issues requiring attention.

Industry Coordination

The securities industry undertook extensive collaborative preparation for T+1 setup. Industry working groups coordinated testing, developed good practices, and addressed common challenges. Continued engagement supports ongoing improvement and addresses post-setup issues.

Summary

T+1 settlement represents a significant market structure change requiring sustained operational excellence. If you are affected, continue optimizing settlement processes, monitoring performance metrics, and investing in capabilities supporting efficient securities settlement in the accelerated environment.

Future Considerations

Market discussion has turned to potential further shortening of settlement cycles, with some jurisdictions considering same-day (T+0) or real-time settlement. If you are affected, consider how current T+1 investments position them for potential future changes and whether additional capabilities may be required.

Distributed ledger technology and other innovations may enable settlement cycle changes not feasible with traditional infrastructure. If you are affected, monitor technology developments and participate in industry discussions about settlement infrastructure evolution.

Global harmonization of settlement cycles remains an ongoing consideration, with international coordination potentially driving future changes. Organizations with cross-border operations should engage with global settlement discussions and prepare for potential international convergence on settlement timelines.

Continuous improvement of settlement operations supports competitive positioning while managing risk in securities markets. Investment in automation, exception management, and monitoring capabilities benefits organizations regardless of specific settlement cycle requirements.

Staff training ensures personnel understand T+1 requirements and their roles in settlement processes. Documentation of policies and procedures supports both operational consistency and regulatory compliance demonstrations. Regular review of settlement metrics identifies opportunities for further improvement and risk reduction in the accelerated settlement environment.

Operational Impact

T+1 settlement shortens the standard settlement cycle from two business days to one, reducing counterparty risk and capital requirements. Market participants must optimize trade processing, reconciliation, and exception handling to meet compressed timelines. Operational resilience becomes critical with less time for error correction.

Technology Requirements

Real-time trade matching and automated affirmation processes replace manual workflows. System upgrades address throughput requirements for same-day processing. Integration with industry utilities like DTCC ensures coordinated settlement across market participants.

Global Coordination

International investors must align funding and trade instruction timing with US market settlement windows. FX settlement coordination becomes more complex with compressed timelines. Correspondent bank relationships require updated cutoff times and communication protocols.
