Wholesale FX Treasury for Inter-Branch and B2B Flows

Wholesale FX (B2B)

Handle high-volume currency transactions with partner institutions through structured treasury workflows.

Technical highlights

  • Wholesale operations generate deterministic operation numbers with WHO date-time pattern.
  • Treasury creation atomically updates bought and sold currency balances for the selected till.
  • Treasury history is enriched with till and currency metadata for faster reconciliation.

Large-ticket currency operations

Manage gross buy/sell flows with external counterparties while preserving visibility on transaction status and treasury exposure.

Standardized treasury documentation

Generate treasury slips using a deterministic format (WHO-YYYYMMDD-XXXXX) to simplify reconciliation and controls.

Automated till-balance impact

Treasury operations automatically increase bought-currency balances and decrease sold-currency balances on the selected till.
