The short answer
A push payment is a funds transfer where the sender initiates the movement of money from their account to the recipient. The payer has full agency — no one can pull funds from their account without their action. Push rails include wires, RTP, FedNow, Visa Direct, Mastercard Send, Zelle, bill pay, payroll direct deposit, and same-day ACH credits. They sit opposite pull payments (card authorizations, ACH debits) where the recipient initiates and the sender's bank responds.
The major push rails in 2026
- Wire (Fedwire, SWIFT): Real-time, no cap, $15-$50 per wire. Settlement final — irreversible. B2B treasury backbone.
- RTP (The Clearing House): Real-time, 24/7, credit-only push. Per-transaction limit raised to $10M in 2025. Over 70% of U.S. bank accounts reachable.
- FedNow: Federal Reserve's real-time rail launched July 2023. 24/7 credit push. $500k per-transaction cap. Still growing adoption — ~1,000 institutions live as of 2026.
- Visa Direct: Card-rail push. Sender initiates credit to recipient's Visa-branded card/account. Settles within 30 minutes. Popular for gig-economy instant payouts.
- Mastercard Send: Same concept on Mastercard rails. Merchant-facing API for instant-to-card payouts.
- Same-day ACH credit: See same-day ACH. Slower than RTP/FedNow, cheaper.
- Zelle: Bank-account to bank-account; instant for consumer use. Business Zelle is capped and less universally available.
Use cases for operators
- Marketplace payouts: Pay sellers, gig workers, affiliate partners in minutes rather than waiting for batch ACH. Huge retention/satisfaction benefit.
- Customer refunds: Push refunds to credit-card accounts via Visa Direct / Mastercard Send when speed matters (flight cancellations, urgent service credits).
- Vendor / supplier payments: RTP or FedNow for operational payments under $10M, beats a wire on cost.
- Insurance claim payouts, loan disbursements: Instant claim-to-cash is a competitive advantage.
- Payroll on demand: Same-day or instant pay features for employees.
What operators need to know
- Push payments are (mostly) irreversible. No chargeback, no dispute, no Reg E (in most B2B push flows). Fraud prevention has to happen BEFORE the push — you can't claw back.
- Fraud shifted post-fraud. With cards, fraudsters steal numbers and push losses to merchants. With push rails, fraudsters trick the sender into pushing funds voluntarily (authorized push-payment fraud — APP fraud). Enterprise-class push programs need beneficiary verification (Confirmation of Payee) and limits.
- RTP and FedNow are credit-only. Neither supports pulling money. For that, you still use ACH debit or card auth.
- Instant-to-card carries fees. Visa Direct and Mastercard Send fees run $0.25-$1.00 per transaction plus percentage — more expensive than ACH, less than a wire.
- Reconciliation differs. Push payments credit recipients immediately. Your treasury system needs to ingest credit confirmations in real-time (ISO 20022 messages) rather than T+1 bank feeds.
- Regulatory attention is growing. CFPB has signaled it wants broader Reg E-style protections for push fraud. Watch for rule changes through 2026-2027.
