RTP Network

What Is the RTP Network?

The RTP network (Real-Time Payments) is a payments infrastructure operated by The Clearing House (TCH), a banking association owned by some of the largest commercial banks in the US. Launched in November 2017, it was the first new core payments system in the US in over 40 years and the first to offer real-time clearing and settlement on a 24/7/365 basis.

At its core, the RTP network allows a sending bank to push funds to a receiving bank with immediate finality. Once a payment clears, it is irrevocable: there are no chargebacks, no hold periods, and no batch processing windows. This distinguishes it from legacy systems like ACH, which processes payments in batches with settlement delays that can range from hours to days.

The network is built on the ISO 20022 messaging standard, meaning rich data (invoice numbers, remittance details, structured references) can travel alongside the payment itself. This makes RTP useful not just for moving money, but for automating reconciliation and reducing manual back-office work.

How It Works

The RTP network operates as a credit-push system. That means only the sender (payer) can initiate a payment: no party can pull funds from another account. Every transaction follows the same basic flow:

1. The payer instructs their financial institution to send a payment to a specific recipient account
2. The sending bank submits the payment message to the RTP network
3. TCH validates the message, checks the sending bank's prefunded balance, and routes it to the receiving bank
4. The receiving bank credits the recipient's account and sends a confirmation back through the network
5. The entire process completes in seconds with immediate finality

Settlement Mechanism

Settlement on the RTP network happens in real time through a joint prefunded account held at the Federal Reserve Bank of New York. Participating banks must deposit funds into this account before they can send payments. When a transaction clears, TCH debits the sender's position and credits the receiver's position within the joint account. This prefunding model eliminates credit risk between participants because funds are always available before a payment is sent.

Request for Payment (RfP)

One of the RTP network's most distinctive features is Request for Payment (RfP), a real-time invoicing mechanism. Instead of sending money, a payee sends a structured payment request to a payer through the network:

1. The payee's bank creates an RfP message (ISO 20022 pain.013) and sends it through the RTP network
2. The payer's bank delivers the request to the payer through their banking app or portal
3. The payer reviews the request, which includes bill details and supporting documents, then approves or declines it
4. If approved, the payment executes instantly as a standard RTP credit push

Because RfP uses the push-payment model, the payer always retains control. No one can debit their account without explicit authorization. This makes RfP more secure than traditional pull-based methods like ACH debits, where a biller initiates the charge. The network charges $0.01 per RfP message to the requester.

Network Parameters

RTP vs. FedNow

The launch of FedNow in July 2023 introduced a second real-time payment rail in the US. While both systems achieve the same core goal (instant, irrevocable payments available around the clock), they differ in important ways:

The two networks are not interoperable: a bank on RTP cannot send a payment to a bank that only supports FedNow, and vice versa. In practice, 58% of US financial institutions that offer instant payments now participate on both rails, adopting a multi-rail strategy to maximize reach.

RTP's advantages include a six-year head start, higher transaction limits, and broader current adoption. FedNow's advantages include direct Federal Reserve access (which may appeal to smaller community banks and credit unions that are not members of TCH) and a liquidity management tool for managing real-time payment flows. Competition between the two rails is expected to drive innovation and reduce costs for participating institutions.

Adoption and Growth

The RTP network has seen rapid growth since its launch. In 2024, the network processed 343 million transactions with a total payment value of $246 billion, representing a 94% increase in value from the prior year. By February 2026, the network set a new daily record of 2.05 million transactions in a single day, with a peak daily value of $8.36 billion.

More than 1,100 financial institutions now participate on the RTP network, covering approximately 90% of US demand deposit accounts. The average payment value rose from $514 in 2023 to $719 in 2024, indicating growing use for business and corporate payments alongside consumer transfers.

Analysts project US real-time payment transaction volumes across all rails to reach 8 billion in 2026 and nearly 13.9 billion by 2028, representing a 31.7% compound annual growth rate.

Use Cases

Business Payments and Treasury

Corporate treasury teams use the RTP network for time-sensitive payments: intercompany transfers, cash concentration, just-in-time vendor payments, and liquidity management. The $10 million limit enables large-value corporate transactions that previously required wire transfers, at a fraction of the cost ($0.045 vs. $25+ for a wire).

Payroll and Gig Economy

Employers and gig platforms use RTP to deliver earned wages instantly rather than waiting for next-day or multi-day ACH settlement. For the roughly 25% of US households living paycheck to paycheck, instant access to earned wages can reduce reliance on payday loans and overdraft fees.

Bill Pay and Invoicing

The Request for Payment feature enables billers to send digital invoices directly to a customer's bank, complete with bill details and supporting documents. Customers approve payment with a single action, and funds settle immediately. This eliminates the multi-day float of ACH-based bill payment and reduces failed payments caused by insufficient funds at debit time.

Insurance and Claims

Insurance companies use RTP for instant claims disbursement, delivering funds to policyholders within seconds of claim approval rather than mailing checks or waiting for ACH.

Risks and Considerations

Irrevocability

RTP payments are final and irrevocable once settled. There is no chargeback mechanism. If a payment is sent to the wrong account or for the wrong amount, the sender must request a return from the recipient's bank, which is not guaranteed. This is a fundamental difference from card networks and ACH, which offer dispute and reversal mechanisms. For businesses, this means payment validation and fraud checks must happen before the payment is submitted, not after.

Fraud Risk

The speed and irrevocability of real-time payments create new fraud vectors. Authorized push payment (APP) fraud, where a victim is tricked into sending a payment voluntarily, is a growing concern across all real-time payment systems globally. Because RTP payments cannot be reversed, victims of APP fraud have limited recourse.

Adoption Gaps

While over 1,100 institutions participate, many are receive-only: they can accept incoming RTP payments but do not yet enable their customers to send them. Approximately 34% of US banks report that their core systems cannot manage the speed and volume required by RTP, and another 34% have concerns about supporting 24/7 availability. Full ubiquity remains a work in progress.

Private Ownership

The Clearing House is owned by a consortium of large banks, which raises questions about governance and equitable access. Smaller banks and credit unions have historically had less influence over TCH's rules and pricing, which was one motivation for the Federal Reserve's decision to build FedNow as a public-sector alternative.

Why It Matters for Digital Payments

The RTP network represents a fundamental shift in US payment infrastructure: from batch-based, business-hours-only processing to always-on, instant settlement. For fintech builders and payment platforms, RTP provides a programmable, standards-based rail that can serve as the foundation for instant payment products.

The broader trend toward real-time payments also creates an interesting parallel with cryptocurrency payment networks. Systems like Spark enable instant, final settlement of Bitcoin and stablecoin payments with similar speed guarantees, but without reliance on traditional banking infrastructure. As real-time expectations become the norm for all types of payments, both traditional rails like RTP and crypto-native solutions address the same user demand: money should move instantly, at any time, with immediate finality.
