Siena - Treasury Trading - white - transparent

Treasury, Trading and ALM Software, Built for Banks Growing in Complexity.

Siena gives growing and specialist banks a single control environment across treasury, trading, risk, and Asset & Liability Management, so issues surface early, controls hold as complexity grows, and governance stands up under scrutiny.

Problem

Growing Banks Face a Familiar Problem.

As volumes rise, products diversify and regulatory expectations increase, systems and processes that once worked become sources of risk and inefficiency. Treasury teams carry the pressure, along with personal accountability.

  • icon_clock

    Risk Surfaces Too Late

    Exposures, settlement issues and balance-sheet impacts often only become clear at end of day, or after a decision has already been made. By then, a manageable issue has become a last-minute escalation.

  • icon_clipboard

    Controls Can't Keep Pace With Complexity

    New products, currencies and regulatory requirements expose the gaps in systems and processes that worked at lower scale. Teams fill the gaps with manual checks, individual judgement and informal workarounds.

    Fragmented Systems, Fragmented Confidence

    Treasury, Trading and ALM data spread across multiple platforms and spreadsheets. Reconciliation becomes routine, ownership becomes unclear, and teams lose confidence in which numbers to trust, even when nothing is formally broken.

AUDIENCE

Built for Banks That Want Institutional Control Without Institutional Complexity.

Siena is designed for banks and financial institutions where treasury complexity is real but a Tier 1 enterprise platform would be over-engineered, over-priced, or simply the wrong fit.

Retail and Commercial Banks

You're managing a diversifying product mix across FX, funding, derivatives and fixed income, and the controls that worked at lower scale are starting to show the strain. You need an integrated treasury, trading and ALM capability without the cost or rigidity of a Tier 1 platform.

Specialist Banks

Your treasury activity is disproportionately complex relative to your size, and regulators know it. Fragmented systems make risk harder to quantify, inflating capital requirements and increasing scrutiny. You need controls that are as defensible as they are functional.

Digital Banks

You've grown quickly and regulatory expectations are now moving faster than your controls. You need a foundation that's robust enough for scrutiny, but flexible enough to keep pace with the bank you're building.

Overseas Subsidiaries With Local Accountability

You carry local regulatory accountability, but your group-level infrastructure wasn't designed for your market or reporting requirements. You need treasury independence that satisfies local regulators without creating a governance conflict with the group.

Benefits

When Treasury, Trading and ALM Share One Control Environment.

Control Before it Becomes Critical

See the Full Picture Before Decisions Are Made, Not After.

Pre-deal limit checking, real-time position keeping and intraday cash ladder visibility mean your team always knows where they stand, before committing to a deal, not after.

  • Make confident decisions, with full awareness of the consequences before you commit.
  • Spot exposures and settlement risks intraday, not at end-of-day when it's too late to act.
  • Replace manual checks with automated alerts when limits or tolerances are approached or breached.
  • Reduce end-of-day reconciliation by holding treasury data in one place across treasury, trading and ALM.

One Shared Truth Across Treasury, Trading and ALM

One Set of Numbers. Trusted Across Every Team, Every Report.

When treasury, trading and ALM operate on shared data, from deal capture through to balance-sheet and regulatory reporting, reconciliation powered by a single set of numbers becomes streamlined, consistent and trusted across every team and report.

  • Manage treasury, trading and ALM end-to-end, not system by system, or spreadsheet by spreadsheet.
  • Work from one set of numbers, built on shared assumptions and a single data model.
  • Trust what you report. No manual adjustments, no offline corrections before a board or regulator conversation.
  • Keep treasury aligned with the rest of the bank as products, volumes and structures change.

Questions We Get Asked at This Stage.

  • We're Not a Standard Bank - Does Siena Work for Institutions With Complex or Non-template Operating Models?

    Yes. Siena is specifically designed for banks where standard templates don't account for the nuances of the operating model. Implementation starts with structured scoping workshops that map your products, processes, workflows and reporting requirements before configuration begins, so the platform reflects how your treasury function works, not a generic approximation of it. This is where we consistently outperform faster, more standardised alternatives.

  • How Does Implementation Work, and Who is Accountable When Things Get Complex?

    Our delivery model is built around continuity and accountability, The same team that scopes your implementation works through configuration, testing and go-live, there are no handovers to different delivery functions mid-project, Senior Eurobase experts are directly involved throughout, not just at kick-off. Our standard implementation processes are designed to manage complexity. Detailed up-front scoping work assures that projects deliver the right scope on time and on budget,

  • Can Siena Handle Our Current Scale, and Will It Hold as We Grow?

    Siena is modular and designed to scale from early treasury maturity to complex, multi-entity operations, without requiring re-platforming as your bank grows. We work with banks at very different stages: some are implementing treasury controls for the first time, others are replacing disconnected specialist tools as their product range and complexity increases. The same platform serves both.

  • We Already Have Some Treasury Systems in Place. Does Siena Replace Everything, or Can It Integrate?

    Both are possible, and the right answer depends on your current situation. Siena integrates with core banking systems, ERPs and surrounding platforms via open APIs and ready-to-deploy adaptors, so it doesn't require a wholesale replacement on day one. Many clients find that consolidating onto Siena removes the reconciliation overhead and fragmented ownership that comes with maintaining multiple specialist systems. We'll give you an informed view of what makes sense for your situation.
