Payment Rails · Cross-Border T212 · T254 · T255 · T229 7 Rails Benchmarked ISO 20022 Zero PII

Global Real-Time Rails Comparator

Pick a payment corridor. The model scores SEPA Instant, FedNow, RTP (TCH), PIX, UPI, FPS, and SWIFT gpi on speed, finality, cost, ISO 20022 readiness, and scheme participation complexity. Weights are user-tunable; the recommendation reflects the corridor's actual technical and regulatory constraints. Export a boardroom-ready Policy Mandate.

ISO 20022 column note: PIX and UPI are not natively ISO 20022 rails — their scores reflect message-structure compatibility and data-richness relative to ISO 20022 standards, not native adoption. SEPA Instant and FedNow are full ISO 20022 implementations.

Panel 03 · Recommendation

Best Rail for This Corridor

Composite-weighted winner + sensitivity callouts

Cross-border note: FedNow and RTP (TCH) are domestic US rails scored on a single-leg basis; they are not end-to-end cross-border capable. For cross-border corridors a second-leg rail (e.g. SWIFT gpi or a local instant rail in the destination country) is required. Scores for these rails on non-US corridors reflect the US-side leg only and a cross-border penalty is applied.
