Executive Summary

The United States operates a unique dual-operator payment infrastructure model. The Federal Reserve provides Fedwire (RTGS), FedACH (batch), and FedNow (instant) — the public-sector rails. The Clearing House, owned by 22 major banks, operates CHIPS (large-value netting), RTP (instant), and EPN (batch ACH) — the private-sector rails. This creates competition and redundancy at every layer: RTGS (Fedwire), netting (CHIPS), batch (FedACH vs EPN), and instant (FedNow vs RTP). The regulatory framework involves the Federal Reserve, OCC, FDIC, CFPB, and state regulators.

How It Works

Settlement Model

Mixed: RTGS (Fedwire), Hybrid netting (CHIPS), DNS (ACH), RTGS/Prefunded (FedNow/RTP)

Message Standard

ISO 20022 for Fedwire (March 2025), CHIPS (April 2025), FedNow (native), RTP (native). ACH uses Nacha format.

Max Transaction

Fedwire: No limit. CHIPS: No limit. FedNow: $10M. RTP: $10M. ACH: $1M (Same-Day).

Clearing Mechanism

Multiple: direct RTGS (Fedwire), netting (CHIPS), batch clearing (FedACH/EPN), instant settlement (FedNow/RTP)

Settlement Cycle

Varies by system: Fedwire operates ~21 hours/day weekdays. FedNow and RTP operate 24/7/365. ACH processes multiple daily windows. CHIPS operates during NY business hours.

Message Flow

Payment flows depend on the rail: large-value payments typically route through Fedwire or CHIPS. Retail payments use ACH (batch) or FedNow/RTP (instant). Cross-border USD payments primarily flow through CHIPS and correspondent banking. All rails ultimately settle in Federal Reserve balances.

Typical Use Cases

Comprehensive: interbank settlement, corporate treasury, payroll, consumer transfers, government payments, cross-border USD clearing

Participants & Access

Membership Requirements

Federal Reserve systems: open to institutions with Federal Reserve master accounts. TCH systems: participation criteria set by TCH. Universal reach through correspondent banking.

Governance & Risk

Governance Model

Dual governance: Federal Reserve (public, statutory mandate) and The Clearing House (private, owned by 22 banks). Nacha provides rules for the ACH network. FSOC designates systemically important FMUs. State and federal banking regulators oversee participants.

Concentration Risk

Systemic concentration at the Federal Reserve account level — all systems ultimately settle in Fed balances. The dual-operator model provides competition but both operators are deeply interconnected.

Resilience & Business Continuity

The dual-operator model provides structural resilience. If TCH systems experience issues, Federal Reserve systems can continue (and vice versa). Multiple settlement windows and real-time alternatives reduce systemic pressure.

Dispute Resolution

Varies by system: UCC Article 4A (Fedwire), Nacha Operating Rules (ACH), specific operating rules (FedNow, RTP, CHIPS). Consumer protections under Regulation E (EFTA) and Regulation Z (TILA).
