Settlement Infrastructure
85% traditional banking rail
Swiss private bank custody, EU correspondent network. Payroll, debt servicing, institutional counterparties.
5.4 days avg. settlement · 61 bps friction · 2.1% operational cash drag (annualized)
15% hybrid rail
4 regulated OTC desks (Singapore, UAE, Switzerland, US). Self-custody multi-sig 3-of-5. Stablecoin settlement.
9 hours avg. settlement · 10 bps friction · 0.4% operational cash drag (annualized)
Panel II — Three transactions enabled by settlement velocity
Cross-border deals executed within counterparty windows structurally incompatible with traditional rail timing.

Panel III — Settlement velocity as the operational driver
Cumulative excess return — hybrid versus counterfactual all-traditional allocation. Three deals in Q1–Q2 2025 account for the majority of accumulated outperformance.
Counterfactual benchmark: identical asset allocation under traditional banking-only settlement architecture, applying client’s pre-rebalance settlement times (5.4 days avg) and friction costs (61 bps avg).
cumulative operational excess return vs single-rail counterfactual (bps)
Hover over the line for transaction-level detail.
Excess Return · Portfolio
+290 bps
Total Return · Real
+14.7%
Total Return · Counterfactual
+11.8%
Both architectures coexist within the portfolio. The hybrid component, sized to client risk profile, contributed measurable operational advantages — primarily through execution velocity — that translated into +290 bps of excess return at the portfolio level over 18 months.
