All fee and timeline data is embedded at build time. No data leaves your browser.

Fee and settlement data is sourced from published rail operator documentation, central bank specifications, and industry surveys. All figures are indicative — actual fees depend on your PSP contract, transaction volume tiers, FX provider, and bilateral agreements. Validate against your live PSP pricing before committing to a rail migration.

Regulatory compliance notes for key payment rails across PSD2/PSD3 (EU/EEA), CFPB 1033 (US), and SWIFT MX migration requirements. Not legal advice — verify with your compliance team before live deployment.

EU / EEA — PSD2 & PSD3 / PSR
SEPA Instant — SCA Compliance
Full SCA required at payment initiation under PSD2 Art. 97. Low-Value exemption (≤€30) available. TRA exemption available for ASPSP fraud rate below EBA RTS thresholds. Instant confirmation ≤10s per SEPA Inst rulebook Nov 2025 amendments.
SEPA Instant — IBAN Reachability
As of Jan 2025, all eurozone PSPs must send and receive SEPA Instant under the EU PSR (Payment Services Regulation). Remaining gap: non-euro EU member states (Bulgaria, Czechia, Hungary, Poland, Romania) have extended deadlines to Oct 2025.
PSD3 / PSR — Transition Timeline
PSD3 and PSR are in trilogue; expected to enter into force 2026–2027. Key changes: enhanced open banking data access, IBAN/name verification obligation (like UK CoP), expanded SCA exemptions for embedded finance. Plan for consent dashboard updates (see Tool 18).
SWIFT CBPR+ MX Migration
SWIFT coexistence period ends Nov 2025. All cross-border SWIFT messages must use ISO 20022 MX format. Structured address fields (PostalAddress) become mandatory. Truncation of enriched data to legacy MT counterparties is a known risk — validate with Tool 77.
US — CFPB 1033 & Dodd-Frank
FedNow — Reg E Coverage
FedNow is subject to Regulation E for consumer-initiated transfers. Error resolution rights apply within 60 days of statement. PSPs must provide written confirmation and credit provisionally within 10 business days pending investigation completion.
RTP / FedNow — CFPB 1033 Data Access
CFPB Section 1033 Final Rule (Oct 2024) requires data holders to provide machine-readable transaction data to authorised third parties on consumer request. FDX v5 API schema is the recognised standard. Phased compliance: >$500B assets → Apr 2026; >$10B → Apr 2027; smaller → 2028–2030.
ACH — Same-Day Limit Increase
NACHA raised the Same-Day ACH per-transaction limit to $1,000,000 in March 2023. Corporate credit transactions over this threshold require Next-Day ACH or a real-time alternative. Verify AML/BSA obligations for high-value A2A flows — FinCEN monitoring applies.
SWIFT gpi — US Outbound
SWIFT gpi provides end-to-end tracking and confirmed SLA for cross-border wires. OFACscreening required for all US-outbound wires. BIS CPMI Report on FX Settlement Risk (2023) recommends PvP where available; USD corridors to EUR/GBP should consider CLS settlement where eligible.
Other Rails — Regional Compliance Highlights
PIX (Brazil) — LGPD & BCB
PIX is mandatory for all financial institutions with >500K active accounts per Banco Central do Brasil. Real-time compliance with Brazil's LGPD data protection law required. PIX keys (CPF, CNPJ, phone, email, random) must not be stored or processed beyond transaction necessity.
UPI (India) — NPCI + RBI
UPI is regulated by NPCI under RBI's Payment and Settlement Systems Act. Cross-border UPI (Singapore, France, UAE) is live. Transaction limits: ₹1 lakh per day for most use cases; ₹2 lakh for specific categories (capital markets, IPO). Data localisation required for payment data.
Faster Payments (UK) — PSR & CoP
Confirmation of Payee (CoP) is mandatory for UK PSPs from Jun 2023 (PSR direction). All outgoing payments >£100 require name match against beneficiary account. UK PSR review of APP fraud reimbursement (Oct 2024): mandatory reimbursement up to £85K for most APP fraud cases.
NPP (Australia) — CDR & NPPA
Australia's New Payments Platform is operated by NPPA. Open banking under CDR requires ABA-registered banks to support NPP for PayID-linked A2A payments. AUSTRAC AML/CTF compliance applies to all NPP transactions. PayID lookup raises privacy considerations — implement with NPPA guidance.

Full reference table for all 10 rails embedded in this tool. Fee figures are indicative typical PSP costs, not guaranteed rates. Settlement windows are standard operating conditions.

Rail Region Operator Typical Fee Settlement Window Max Tx Limit 24/7 ISO 20022 Cross-border

Fee methodology: "Typical fee" represents a blended estimate of PSP pass-through fees at $10K transaction value based on publicly available rate cards (Stripe Treasury, Plaid, Modulr, Wise Business, etc.) and published operator fee schedules. Actual fees vary significantly by volume tier, PSP relationship, and negotiated agreements.

SWIFT gpi: Fee includes SWIFT messaging fee ($5–$15), correspondent bank fees ($15–$40 estimated), and FX spread (0.3–1.5% indicative). Total cross-border wire cost varies widely — gpi tracking provides visibility but does not control correspondent charges.

ACH: NACHA operator fee is ~$0.001 per item. PSP fees typically $0.20–$2.00 per transaction. Same-Day ACH incurs a 5.2 cents per-item NACHA surcharge (effective March 2021). Returns are typically $2–$5 per item.

Data vintage: May 2026. PIX and UPI limits reflect March 2026 NPCI/BCB guidance.
