BSG

Bank Single Gateway in Europe

12 providers listed on TreasuryMap

Bank Single Gateway (BSG) solutions streamline multi-bank connectivity by providing a single access point through which companies can send and receive financial messages to and from all their banking partners. They replace direct, bilateral connections with a standardised communication hub, reducing complexity, cost, and operational risk. BSG platforms support SWIFT, ISO 20022, EBICS, APIs, and legacy bank file formats (MT940, camt.053, XML, CSV), and are the backbone of modern treasury bank connectivity architectures.

Why BSG matters for corporate treasurers

As soon as a company works with more than a handful of banks, bilateral connections become costly and fragile. A single gateway centralises connectivity, normalises formats and removes a major source of operational risk and reconciliation lag. It is the plumbing on which payments, reporting and forecasting all depend.
