IR-swap blotter and dealer-confirmation email folder — "Swap resets post from a blotter that was typed after the dealer confirm arrived"

Operational Forensic Breakdown

Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.

Model in Calculator
Spreadsheet Failure ModeManual Workflow

Root Operational Bottleneck

Interest-rate swaps are typed into a blotter from dealer confirmation emails after the reset, so the register receives the ticket only when the paste finishes.

Control Hazard & Audit Exposure

Swap resets post from a blotter that was typed after the dealer confirm arrived, and interest starts on a ticket that does not match the dealer.

Deterministic Software ReplacementClient-Owned Architecture

Interest-Rate Swap Gateway that Posts Only After Dealer Confirm Matches the Ticket

IR-swap execution gateway that captures the dealer confirm and posts the reset only when notional, rate, and reset date match the ticket.

Continuous Assertion Rule

Swap assertion: an interest-rate swap reset cannot post unless a dealer confirmation matches the ticket on notional, rate, and reset date.

Before & After Pipeline Schematic

Three-stage comparison between manual workbook reconciliation and automated rule-based execution.

Pipeline Archetype: Continuous API Ingestion & Immutable Ledger
Direct ERP, banking, and billing API webhooks replace manual CSV export/import routines with real-time balance propagation.
