Instant Payment Systems Around the World: UPI vs Pix vs FedNow vs SEPA Instant

Every day, India's UPI handles more payments than most countries make in a month. Meanwhile, Brazil's Pix has reached nine in ten adults in under six years. By contrast, the US and Europe are still catching up.

So why did some instant payment systems take off while others stayed small? This guide compares the five that matter most, with the latest numbers, and explains what made the difference.

What is an instant payment system?

An instant payment system moves money from one bank account to another in seconds. It runs 24 hours a day, every day of the year, including weekends and holidays. The money arrives in full and in final form, so the receiver can use it straight away.

That sounds simple. However, older bank transfers often took hours or days, and many still stop over weekends. Instant payment systems remove that wait. As a result, they now compete with cards and cash at checkouts, in bill payments and between friends.

Most of these systems share three features:

• Account to account. Money moves directly between bank accounts, without a card network in the middle.
• Simple aliases. You pay a phone number, email or QR code instead of typing long account numbers.
• Low or zero cost. Consumers usually pay nothing, which helps adoption.

The five big instant payment systems at a glance

The gap in scale is huge. In fact, UPI processes more payments in a single day than FedNow processed in all of 2025.

UPI vs Pix: the two giants

India and Brazil built the world's two most successful instant payment systems. They took slightly different routes to get there.

UPI launched in 2016 under NPCI, an organisation owned by Indian banks. In September 2026, it handled 24.07 billion payments worth ₹29.37 lakh crore, according to Business Today. Daily volume crossed 800 million for the first time, at 802 million payments a day.

Pix launched in November 2020, and Brazil's central bank runs it directly. In 2025, it processed 79.8 billion payments worth R$35.36 trillion, up 33.6% on 2024. It now reaches more than 175 million users, about 93% of Brazil's adults. On 4 September 2026, it set a new daily record of 318 million payments, according to The Rio Times.

Both systems won for the same core reasons:

• They are free for ordinary users.
• They work through QR codes at almost any shop or stall.
• They let people pay a phone number or ID instead of an account number.
• A strong public body pushed every bank to join.

They also add features at a similar pace. UPI AutoPay handles recurring payments such as subscriptions. Pix launched its own version, Pix Automático, on 16 June 2025, and contactless Pix in February 2025.

There is one key difference in the money. UPI was free for merchants for years, but India is changing that. From 15 October 2026, larger merchant payments above ₹2,000 carry a 0.4% fee. Our UPI MDR explainer covers the details.

FedNow vs UPI: why the US is different

FedNow launched in July 2023, seven years after UPI. It already counts more than 1,600 participating banks and credit unions. However, it works very differently in practice.

In 2025, FedNow settled more than 8.4 million payments worth $853.4 billion, according to Digital Transactions. The average payment was $101,435. In other words, businesses use it mostly for large transfers, such as payroll, supplier bills and moving cash between accounts. The Fed raised the limit per payment to $10 million in November 2025.

Several things hold back everyday use in the US:

• Cards work well. Most Americans already pay with debit cards, credit cards and apps, and many like the rewards on credit cards.
• Joining is optional. Each bank decides whether to connect, and the US has thousands of banks.
• There is no national QR standard. Shops have no common way to accept instant bank payments at the till.

The US also has a private rival. The RTP network, run by bank-owned The Clearing House, has offered instant payments since 2017. Two systems split the market, so neither has the reach of UPI or Pix.

SEPA Instant: Europe catches up by law

Europe launched SEPA Instant Credit Transfer in November 2017. For years, though, many banks offered it late or charged extra. So the EU passed a law to force the change.

Under the EU Instant Payments Regulation, banks in the euro area had to:

1. Receive instant euro transfers by 9 January 2025.
2. Send them by 9 October 2025.
3. Charge no more for an instant transfer than for a standard one, also from 9 October 2025.
4. Offer Verification of Payee, a free check that the name matches the account, from the same date.

EU countries outside the euro area follow in 2027. Payment and e-money institutions in the euro area also join by 9 April 2027, according to the ECB.

As a result, Europe now has the rules for instant payments everywhere. What it lacks is a single consumer brand like UPI or Pix, so adoption at shop tills will take longer.

Faster Payments: the UK's early mover

The UK was years ahead of everyone. Faster Payments launched in May 2008, long before most countries had an instant payment system at all.

In 2025, it carried 5.548 billion payments worth £4.838 trillion, according to Pay.UK. That is 9% more payments than in 2024. Most of the growth came from single immediate payments, the everyday transfers people make in banking apps.

However, Faster Payments shows that being first is not enough. The UK still relies heavily on cards at checkouts, because the system grew up around bank transfers rather than shop payments.

What makes an instant payment system succeed?

Put the five systems side by side and a clear pattern appears. The winners got five things right.

1. Free for consumers. People switch when it costs them nothing.
2. Easy to pay a shop. A shared QR code standard turned UPI and Pix into checkout tools, not just transfer tools.
3. Simple aliases. Paying a phone number beats typing an account number.
4. A strong central push. NPCI and Brazil's central bank brought every major bank on board quickly.
5. Weak alternatives. In India and Brazil, many people had no credit card, so instant payments filled a real gap.

By contrast, the US and Europe already had good card networks. So their instant payment systems must compete on cost and speed for businesses first.

What comes next

The next frontier is crossing borders. Today, most instant payments stay inside one country or currency area. A few systems already have bilateral links, and the BIS Innovation Hub's Project Nexus aims to connect national systems more widely.

Meanwhile, stablecoins chase the same goal from a different direction. Our guide to how stablecoins make money explains that rival model.

The bottom line

Instant payment systems have already won in India and Brazil, where they became the default way to pay. The UK got there early but stayed focused on bank transfers. Meanwhile, Europe is forcing adoption by law, and the US is growing from business payments up.

For readers everywhere, the trend points one way. Money will move faster and more cheaply between accounts, and the next big question is who gets paid when it does.
