Which countries have instant payment systems? A 2026 reference table

Instant payment systems now run in most large economies: Pix in Brazil, SPEI in Mexico, RTP and FedNow in the US, SEPA Instant in the euro area, Faster Payments in the UK, UPI in India, Transfers 3.0 in Argentina, and Bre-B in Colombia. Each settles in seconds, around the clock. BlindPay pays out over Pix, SPEI, RTP, and Transfers 3.0.

The table below is the reference. Every launch date, hour, and limit comes from the operator or central bank page linked next to it. Where an operator doesn't publish a figure, the cell says so instead of guessing.

Key takeaways

• All ten systems below run around the clock and credit the recipient in seconds or close to it. The BIS counts more than 70 countries where domestic payments work this way.
• Limits vary a lot: RTP and FedNow allow $10 million per payment, UK Faster Payments up to £1 million at scheme level, and Pix leaves maximums to each bank.
• Instant rails are domestic. Linking two of them across a border is still rare, so most cross-border payouts need a separate leg between countries.
• The fastest cross-border payout ends on the recipient's instant rail. The cheapest one avoids correspondent hops and wide FX spreads before it gets there.
• BlindPay pays out over Pix, SPEI, RTP, and Transfers 3.0 in minutes, and over ACH, TED, ACH Colombia, SEPA, and SWIFT (POBO/COBO) on business-day timelines.

What is an instant payment system?

An instant payment system is a domestic network that moves money between bank or payment accounts in seconds, makes the funds usable right away, and runs every hour of every day.

Three things separate it from older rails:

• Speed. The recipient's bank credits the account within seconds, not at the end of a batch.
• Hours. No cut-off times, weekends, or bank holidays. A Pix sent at 3 a.m. on a Sunday lands at 3 a.m. on a Sunday.
• Finality. Most schemes treat a completed payment as final. The Banco Central do Brasil, for example, describes Pix transactions as irrevocable once started.

Batch rails such as ACH, domestic wire, and SWIFT work differently. They process on business days, with daily cut-offs, and can take one to five business days end to end. Why cross-border payments are slow walks through where those days go.

Which countries have instant payment systems?

Brazil, Mexico, the US, the euro area, the UK, India, Argentina, Colombia, and Singapore all run one, along with dozens of other countries. Here is the reference table.

Sources, row by row: Banco Central do Brasil on Pix, Banco de México on SPEI, The Clearing House on RTP, the Federal Reserve's FedNow launch release and September 2025 limit increase, the European Payments Council on SCT Inst, Pay.UK on Faster Payments, NPCI's UPI launch release, BCRA Communication A 7153, Banco de la República on Bre-B, and ABS on PayNow.

A few notes the table can't hold:

• RTP and FedNow both allow $10 million per payment. RTP got there first, and the Federal Reserve announced FedNow's increase from $1 million to $10 million on September 9, 2025, effective November 2025. Banks can still set lower limits for their own customers.
• SEPA Instant gives the whole chain a nine-second budget under the 2025 rulebook, inside the ten-second ceiling set by EU law.
• Transfers 3.0 is the name for Argentina's framework of interoperable immediate transfers, set by BCRA Communication A 7153 of October 30, 2020. Phase 1 went live on December 7, 2020.
• Bre-B started full interoperability on September 23, 2025, with a controlled phase before opening to all users on October 6, 2025.

What did the EU Instant Payments Regulation change?

It made instant euro transfers mandatory for most payment providers. Regulation (EU) 2024/886, the Instant Payments Regulation, amended the SEPA Regulation and entered into force in April 2024.

The dates that matter, per the European Payments Council:

1. January 9, 2025. Euro-area banks had to be able to receive instant credit transfers.
2. October 9, 2025. Euro-area banks had to be able to send them, along with the other obligations that took effect that day, including payee verification.
3. Later dates. Payment institutions, e-money institutions, and providers in non-euro EEA countries follow on a later schedule.

For a business paying into Europe, the effect is simple. Almost every euro account can now receive an instant transfer. Whether the payment actually arrives in seconds depends on whether the sender's provider uses SCT Inst or standard SEPA, which settles on business days.

Are instant payment systems connected across borders?

A few are, most aren't. Each system above is domestic, so a payment from the US to Brazil can't ride Pix the whole way.

Two linking models exist today:

• Bilateral links. The Association of Banks in Singapore lists PayNow linkages with Thailand's PromptPay, India's UPI, and Malaysia's DuitNow. Each link is its own project between two countries.
• Multilateral hubs. The BIS Innovation Hub's Project Nexus designed a standard way to connect many instant systems at once. In 2025, the central banks of India, Indonesia, Malaysia, the Philippines, Singapore, and Thailand formed Nexus Global Payments to take it live, and the BIS handed the project over.

None of these links reach the corridors most Latin American payouts use. A US company paying a supplier in São Paulo still needs a leg between the two countries. That leg is either a correspondent banking chain (a SWIFT wire) or a stablecoin that settles on a blockchain and is converted to reais before the Pix leg. The hub page on real-time cross-border settlement explains how those two legs fit together.

Which rail is fastest, and which is cheapest?

For the final leg, a domestic instant rail is both. For the whole cross-border payment, speed and cost depend on what happens before the money reaches that rail.

Speed comes down to the slowest step. If the leg between countries takes three business days, a Pix that lands in two seconds doesn't help much. Stablecoin payout settlement times shows how a stablecoin leg plus a local rail compares by country.

Cost works the same way. The Banco Central do Brasil says Pix carries no fees for people and low cost for businesses, and ABS says PayNow is free to retail customers. The expensive parts sit upstream: correspondent fees and the FX spread. What cross-border payments cost in 2026 breaks those down by corridor.

A quick decision guide for payouts:

How do you choose the rail for each payout?

Start from where the recipient banks and what they can receive, then pick the fastest rail that covers it. Here is the order most payment teams use:

1. Check the recipient's country and currency. That narrows the options to one or two domestic rails.
2. Check what details you hold. Pix needs a Pix key or bank routing, SPEI needs an 18-digit CLABE, RTP needs an RTP-eligible routing number. The details you need to pay someone in Brazil or Mexico lists them.
3. Check timing. If the payment must land tonight or on a weekend, only an instant rail works. Stablecoin payout cut-off times on weekends and holidays covers the batch rails.
4. Check the amount. Large payments can hit per-bank limits on instant rails, even where the scheme cap is high.
5. Fall back to SWIFT where no local rail reaches the recipient, or where the recipient needs dollars in their account.

How does BlindPay route payouts across instant and batch rails?

BlindPay puts eleven bank rails behind one payout API. You create a quote against the recipient's bank account, and the account type decides the rail.

Those windows come from the payment methods and cut-off times docs. They are rail windows; very high volume can stretch any of them.

How a payout runs:

• Funding at send time. The stablecoins (USDC or USDT) come from a wallet when you execute the payout, so there is no pre-funded balance sitting in each country.
• A quote first. Each payout quote shows the market rate (commercial_quotation), the rate after BlindPay's fee (blindpay_quotation), the flat fee, and the exact amount the recipient receives. It expires after 5 minutes by default.
• Compliance in the flow. Every payout runs through a customer who has passed KYC or KYB, with transaction screening on every payment.
