Executive Summary

The ACH Network is the backbone of US retail payment processing, handling over 30 billion transactions annually — payroll, bill payments, government disbursements, and business-to-business payments. FedACH is the Federal Reserve's ACH operator, processing approximately 60% of ACH volume alongside EPN (The Clearing House's ACH operator). Nacha sets the rules. Same-Day ACH, introduced in 2016, provides faster processing with a $1 million per-transaction limit.

How It Works
Settlement Model
Deferred Net Settlement (DNS)
Message Standard
Nacha ACH format (proprietary batch format), with ISO 20022 support for international ACH (IAT)
Max Transaction
$1,000,000 per transaction (Same-Day ACH limit, raised from initial $25,000 in 2016)
Clearing Mechanism
FedACH (Federal Reserve, ~60% market share) and EPN (The Clearing House, ~40%). Both operators are interoperable.
Settlement Cycle
Multiple daily settlement windows. Standard ACH: next-business-day settlement. Same-Day ACH: three processing windows per day with same-day settlement. Settlement in Federal Reserve balances.
Message Flow
The originator submits ACH entries to their Originating Depository Financial Institution (ODFI). The ODFI batches entries and transmits to FedACH (or EPN). FedACH sorts entries by Receiving Depository Financial Institution (RDFI) and delivers to each RDFI. Net settlement positions are calculated and posted to Federal Reserve accounts. RDFIs process entries to end-customer accounts.
Typical Use Cases
Payroll (Direct Deposit), bill payments, government benefits (Social Security, tax refunds), business-to-business payments, insurance premiums, subscription payments

Participants & Access
Membership Requirements
Participation open to all federally insured financial institutions through their Federal Reserve account (for FedACH) or EPN membership. Third-party processors may originate on behalf of institutions.
Governance & Risk
Governance Model
Nacha is the self-regulatory organisation setting ACH rules. The Federal Reserve and EPN operate the infrastructure. Nacha membership includes over 10,000 financial institutions. Rule changes follow a public comment process.
Concentration Risk
Low — two operators (FedACH and EPN) provide competitive redundancy. Near-universal participation among US financial institutions. However, ACH is critical infrastructure — disruption would affect payroll, government payments, and bill processing for hundreds of millions of Americans.
Resilience & Business Continuity
Dual-operator model provides systemic resilience. FedACH leverages Federal Reserve infrastructure. Settlement in central bank money eliminates counterparty risk. Same-Day ACH provides faster processing alternative.
Dispute Resolution
Nacha Operating Rules govern returns, disputes, and unauthorised transactions. Regulation E (EFTA) provides consumer protections for electronic fund transfers. 60-day return window for unauthorised consumer debits.
Pricing
FedACH pricing per item with volume-based tier discounts. Same-Day ACH carries an additional fee.
Transaction fee: $0.0023 per item (FedACH forward, high volume tier)
Connectivity
settles via
Fedwire
ACH net settlement positions are posted to Federal Reserve accounts (same infrastructure as Fedwire)
complementary to
FedNow
FedNow provides instant alternative for payments that previously used Same-Day ACH
Peer Comparison
FedACH/ACH is comparable to Bacs (UK) and SEPA SCT (Europe) as a batch credit transfer and direct debit system. ACH is unique in its dual-operator model (FedACH + EPN). Same-Day ACH provides faster processing than traditional batch, approaching (but not matching) instant payment speeds. ACH Direct Debit is the US equivalent of SEPA SDD and Bacs Direct Debit.

BCB Adds Automatic Blocking Controls to PIX Settlement Accounts After R$100 Million Breach
Resolution BCB No. 554, effective March 30, requires all direct participants in Brazil's instant payment system to configure minimum balance thresholds and optional automatic account blocking for their Conta PI settlement accounts at the central bank.

PayShap Passes 461 Million Transactions but Fees Limit Daily Adoption
South Africa's instant payment system reached 461 million cumulative transactions worth R403 billion through 2025. Despite rapid volume growth, independent research shows PayShap captures less than 7 percent of debit transactions at the most-adopted banks. Per-transaction fees of R6 to R10 create a structural barrier to the daily-use patterns seen in zero-fee systems like PIX and UPI.
