Two Networks, One Goal
The United States now has two competing real-time payment networks: The Clearing House RTP® network (launched 2017) and the Federal Reserve's FedNow® Service (launched July 2023). Both enable instant, 24/7 payments between US financial institutions — but they differ in ownership, reach, features, and strategic positioning. Understanding these differences helps businesses and developers make informed decisions about which network to build on.
At a Glance: Side-by-Side Comparison
| Feature | TCH RTP® | FedNow® |
|---|---|---|
| Operator | The Clearing House (private, bank-owned) | Federal Reserve (government) |
| Launch Year | 2017 | 2023 |
| Transaction Limit | Up to $1 million | Up to $500,000 (default $100K, adjustable) |
| Availability | 24/7/365 | 24/7/365 |
| Message Standard | ISO 20022 | ISO 20022 |
| Request for Payment | Yes | Yes |
| Liquidity Model | Prefunded positions at TCH | Reserves at the Fed |
Reach and Participation
TCH RTP launched first and has built relationships with large financial institutions — many major US banks were early adopters. FedNow, backed by the Federal Reserve, is expected to reach broader community bank and credit union coverage over time, since many smaller institutions already hold Fed accounts and don't need separate liquidity arrangements with a private entity.
For businesses: check whether your specific bank partners support one, both, or neither network. Dual participation is common among larger banks.
Transaction Limits: What You Need to Know
TCH RTP supports transactions up to $1 million, making it attractive for B2B use cases like supply chain payments and real estate disbursements. FedNow currently supports a maximum of $500,000, though the default per-transaction limit is set lower by individual financial institutions and can be raised. For high-value B2B transactions, TCH RTP currently holds an edge.
Request for Payment (RfP)
Both networks support Request for Payment (RfP) — a message where a payee requests funds from a payer. This is transformative for billing and invoicing: instead of pushing payment details and hoping, a business can send a structured payment request directly to the payer's bank. The payer approves and money moves instantly. Both networks implement RfP using ISO 20022 messaging, making the experience similar on either network.
Liquidity Management Differences
One structural difference that matters to treasury teams: TCH RTP requires participants to prefund a position in a joint account at the Fed, managed by TCH. FedNow uses existing Federal Reserve master accounts, which most banks already hold. This gives FedNow a potential onboarding advantage for community banks that find the TCH liquidity model cumbersome.
Which Should You Build On?
The honest answer for most developers and businesses is: both, if possible. Dual-network support maximizes payment reach. However, if you need to prioritize:
- Choose TCH RTP if your use case involves large-value B2B payments or you need established bank coverage today.
- Choose FedNow if you're targeting community banks, credit unions, or want to align with the Federal Reserve's long-term infrastructure.
- For consumer-facing apps, work with a fintech-as-a-service provider that abstracts both networks through a single API.
The Competitive Outlook
Rather than one network winning, the US market is trending toward interoperability. Industry groups and regulators have voiced support for eventual technical bridges between the networks. For now, the competitive dynamic is healthy — both networks are investing in new features, lower costs, and expanded participation to grow the overall instant payments ecosystem.
