• Ubiquity & Acceptability: Nearly every U.S. financial institution participates, powering payroll, bill payments, and recurring debits.
• Lower Costs/Predictability: A mature system with stable, often lower, fees.
• Reversibility/Consumer Protections: Defined return windows, error resolution, and unauthorized debit protections.

• Nacha Operating Rules: Cover authorization, returns, reversals, and data security for ODFIs, RDFIs, and third-party senders.
• Error and Unauthorized Debit Procedures: Tools like the Written Statement of Unauthorized Debit (WSUD) protect consumers, with up to 60 days for some claims.
• Risk/Return Thresholds: Unauthorized return and administrative return rates are closely monitored.
• Recordkeeping & Audit: Financial institutions must maintain records and may face Nacha enforcement actions or fines.

Run by The Clearing House, RTP enables 24/7 real-time push payments with immediate settlement.

• Irrevocability: Once settled, RTP transactions cannot be reversed. Compliance teams must focus on prevention, not remediation.
• Dispute Rules: No equivalent of ACH’s “return window.” Errors must be prevented upstream.
• AML/Fraud Monitoring: Instant settlement means near-zero time for conventional reviews. Real-time identity checks and sanctions screening are essential.

Launched in July 2023, FedNow is the Federal Reserve’s real-time payments infrastructure, open to any eligible depository financial institution.

• Governing Framework: Regulation J (Subpart C), Operating Circular No. 8, and FedNow Service Operating Procedures. For customer & member transactions, Regulation E also applies.
• Funds Availability: Once credit advice is provided, funds must be made available immediately.
• Operational Controls: Digital signatures, encryption, ISO 20022 message formatting, and settlement timeouts.
• AML/Fraud/Sanctions: Federal expectations for robust compliance programs, with real-time monitoring to prevent both legal and reputational risks.

• ACH: Best for high-volume, recurring, or non-urgent payments with cost efficiency.
• RTP: Ideal for emergencies, instant disbursements, and P2P where speed and irrevocability are critical.
• FedNow: Attractive for financial institutions seeking inclusivity, federal oversight, and enhanced fraud/risk controls.

Managing ACH, RTP, and FedNow simultaneously raises complexity. Success depends on:

• Governance: Policies that define rail usage, authorization standards, and escalation paths.
• Training: Staff must understand Nacha rules, Regulation E, Regulation J, and RTP/FedNow procedures.
• Technology: ISO 20022 readiness, AML integrations, and systems capable of real-time reconciliation.
• Monitoring & Reporting: Keep a close eye on return/exception rates, unauthorized debits, and fraud loss metrics.

Managing ACH, RTP, and FedNow simultaneously adds new layers of operational and compliance complexity. Compliance teams must navigate overlapping regulations, evolving fraud risks, and increasing expectations for real-time monitoring.
