How do I ensure my trade settlement workflow with a settlement platform is compliant with T+1 requirements and audit controls?

To ensure your trade settlement workflow is compliant with T+1 requirements and has strong audit controls, design the process around three things:

1. speed — all trade data must be validated and confirmed fast enough to settle the next day,
2. control — clear ownership, exception handling, and approvals,
3. evidence — every critical step must be logged, time-stamped, and reproducible.

1) Build the workflow around T+1 deadlines

Map the full post-trade timeline from execution to settlement:

• Trade capture
• Allocation
• Confirmation/matching
• Instruction generation
• Settlement submission
• Exception resolution
• Final settlement confirmation

For T+1, set internal cutoffs well before market deadlines. Common best practice is to use same-day trade affirmation and intraday monitoring so issues are resolved before end of day.

2) Automate validation as early as possible

Before submitting trades to the settlement platform, validate:

• trade economics
• counterparty details
• standing settlement instructions
• account identifiers
• instrument identifiers
• currency and venue rules
• cutoff times
• holiday calendars and time zones

Use pre-settlement checks so bad instructions are blocked or routed to exception queues immediately.

3) Use exception-based processing

A T+1 workflow should not rely on manual review of every trade. Instead:

• auto-process clean trades
• route breaks to an exception queue
• assign each exception an owner
• track SLA and aging
• escalate unresolved items before settlement cutoff

Maintain clear disposition codes for why a trade failed validation or matching.

4) Implement strong audit controls

Your settlement workflow should produce a complete audit trail for:

• trade creation and amendments
• allocation changes
• confirmation timestamps
• settlement instruction changes
• approval actions
• rejections and overrides
• final settlement status
• any manual intervention

Audit records should include:

• who did it
• what changed
• when it changed
• why it changed
• before/after values
• system or user source
• approval chain, if applicable

Use immutable logging where possible and retain records according to regulatory and internal policy requirements.

5) Enforce segregation of duties

Avoid one person being able to:

• create a trade,
• amend settlement instructions,
• approve the exception,
• and confirm settlement

Typical controls include:

• maker/checker workflow
• separate trading, operations, and oversight roles
• dual approval for sensitive changes
• restricted override permissions
• privileged access reviews

6) Reconcile continuously

Do not wait until end of day. Reconcile throughout the day:

• trade blotter vs. settlement platform
• internal books vs. external confirmations
• matched vs. unmatched trades
• expected vs. actual settlement status
• cash and position movements

Daily reconciliation should also identify stale breaks, duplicated instructions, and mismatched timestamps.

7) Monitor deadlines and settlement risk

Set up monitoring for:

• approaching cutoffs
• failed confirmations
• unmatched allocations
• failed SSI validation
• pending settlement instructions
• settlement fails and partials

Create dashboards and alerts so operations teams know what must be fixed before T+1 deadline.

8) Control change management

Any changes to the settlement workflow, platform configuration, or rules engine should be controlled through:

• documented requirements
• testing in non-production environments
• approval before deployment
• release notes
• rollback plans
• post-deployment validation

This helps prove that the process was operating as designed.

9) Keep policies and procedures current

Document:

• T+1 operating model
• cutoff schedules
• exception handling procedures
• escalation paths
• approval authorities
• audit retention requirements
• incident response steps

Train users regularly and confirm they understand the process.

10) Test and evidence compliance

Perform periodic control testing:

• sample trade lifecycle reviews
• exception samples
• access reviews
• reconciliation testing
• audit log completeness checks
• settlement fail root-cause analysis

Be able to show auditors:

• process maps
• control descriptions
• sample logs
• approvals
• reconciliation reports
• exception tickets
• evidence of remediation

Practical control checklist

A compliant T+1 settlement workflow typically includes:

• same-day trade affirmation
• automated data validation
• clear internal cutoffs ahead of market deadlines
• exception queues with ownership and SLA
• maker/checker approvals
• immutable audit logs
• segregation of duties
• continuous reconciliation
• alerting for aging breaks
• controlled change management
• periodic control testing

Important note

Specific T+1 requirements can differ by:

• asset class,
• jurisdiction,
• counterparty type,
• market infrastructure,
• and regulatory regime.

So the workflow should be reviewed against the applicable rules where you operate.

If you want, I can also help you turn this into a control framework, SOP, or audit checklist for your specific settlement platform.
