P2P payments in commerce: limits merchants must understand in 2026

P2P payments are everywhere in the headlines. Pix in Brazil. UPI in India. RTP and FedNow in the US. Regulators in Europe calling for a “sovereign” alternative to global card networks.

The narrative is simple: instant bank transfers will reshape commerce, lower costs, and reduce reliance on cards. The reality is more nuanced.

In a recent episode of Behind the Checkout, John Lunn sat down with Daniel Kornitzer, Head of Global Partnerships at EBANX, to unpack what peer-to-peer and real-time payments actually mean for merchants. The discussion moved beyond hype and into something more practical: where P2P payments work, where they struggle, and what limits merchants must understand in 2026.

What P2P payments really are in commerce

Peer-to-peer payments began as consumer-to-consumer systems. In India, UPI emerged as part of a broader digital infrastructure initiative that included biometric identity. In Brazil, Pix was launched by the central bank to modernise a cash-heavy and boleto-dominated economy.

Daniel put it clearly: real-time payments “have solved genuine financial inclusion challenges.” In Brazil alone, more than 90 percent of adults use Pix. Hundreds of millions of consumers in India use UPI. These systems lowered barriers to digital payments for small merchants who were previously underserved by traditional card infrastructure.

But here is the key shift for 2026: these systems are no longer just P2P. They are increasingly person-to-business.

Daniel pointed out that in Brazil, a significant share of Pix volume now flows to merchants. What started as a social payment tool has moved into checkout. That transition is what matters for ecommerce and platforms globally.

Adoption does not equal replacement

One of the biggest misconceptions around P2P payments in commerce is that they are replacing cards. They are not.

In Brazil and India, Pix and UPI have grown rapidly. But card volumes have also continued to grow. As Daniel explained, “it’s not a zero-sum equation.” Both rails are expanding because the digital economy itself is expanding.

In emerging markets, real-time payments replaced cash and legacy bank transfer mechanisms first. They did not immediately displace cards at checkout. Instead, they filled gaps where cards were inaccessible or uneconomical.

This distinction is important for merchants in mature markets.

If your assumption is that P2P payments will eliminate cards, you may be misreading the direction of travel. The more likely outcome is coexistence.

The consumer incentive problem in developed markets

Financial inclusion drove adoption in India and Brazil. But in North America and Europe, the dynamics are different.

Consumers already have access to cards, wallets, and instalment products. They often benefit from interest-free grace periods, chargeback rights, and loyalty rewards. As Daniel noted, when he uses a credit card in Canada, he receives rewards, enjoys dispute protections, and gains a free period before repayment. That creates a structural incentive gap.

Why would a consumer choose a bank-to-bank payment over Apple Pay, PayPal, or a rewards credit card if there is no clear benefit? This is where many European open banking initiatives struggled. Merchant enthusiasm was strong because lower processing costs are attractive. Consumer motivation was weaker because there was no compelling reason to switch behaviour.

For P2P payments in commerce to scale in mature markets, incentives must exist. Those incentives may be price-based, loyalty-based, or tied to convenience. Without them, adoption will remain limited to specific verticals such as bill payments or high-value transfers.

The fraud and liability limits merchants cannot ignore

There is a popular narrative that P2P payments are “chargeback free.” That phrase needs careful interpretation.

Most real-time bank transfers are push payments. The consumer authorises the transaction and pushes funds to the merchant. There is typically no traditional chargeback mechanism in the way card networks operate. That can reduce certain types of merchant risk.

However, it does not eliminate fraud. It shifts it. Social engineering scams, authorised push payment fraud, and mule account schemes have grown in parallel with real-time payment adoption. Fraudsters adapt quickly. As Daniel said, payments is an arms race. Taller walls lead to taller ladders.

In the UK, regulators have already intervened to rebalance liability for certain real-time fraud scenarios. In the US, smaller banks have been cautious about scaling real-time payments because decisions must be made in seconds, not days.

For merchants, the limit is clear: do not equate “no chargebacks” with “no fraud exposure.” Risk models must evolve with push-based systems. Operational processes must adapt to irreversible transactions. In 2026, that risk discipline becomes a competitive advantage.

Are regulators pushing too fast?

Another tension discussed in the episode was regulatory momentum. India and Brazil show what happens when regulators actively shape payment infrastructure. Europe has expressed interest in building domestic alternatives to global card networks, partly for sovereignty reasons.

But pushing infrastructure does not guarantee consumer adoption. Daniel described regulators as catalysts who have a dual responsibility: protect financial stability and foster innovation. When they collaborate with industry, adoption can accelerate. When incentives are misaligned, progress can stall.

For merchants, the takeaway is pragmatic. Regulatory support can accelerate supply. It does not automatically generate demand. If you operate in multiple regions, expect uneven adoption curves for P2P payments in commerce.

Domestic rails versus global commerce

One structural limit of P2P systems in 2026 is geography. Pix works brilliantly in Brazil. UPI works brilliantly in India. RTP and FedNow are evolving in the United States. But most of these systems are domestic.

Cross-border interoperability remains complex. Standards alignment, compliance rules, and AML considerations add friction. While there are early projects linking systems regionally, a seamless global real-time fabric is still developing.

For international merchants, this fragmentation matters. Supporting P2P payments means integrating multiple domestic schemes rather than one global rail. That complexity does not eliminate the opportunity. It simply raises the architectural stakes.

Recurring and subscription use cases are the next battleground

Historically, P2P systems focused on instant transfers. Now they are moving into recurring payments. Brazil has introduced Pix Automático. India supports UPI Autopay. These features allow subscription and recurring billing models to sit on real-time bank rails.

This is where commerce strategy becomes more interesting. If bank-based recurring payments become reliable and widely adopted, they can compete directly with stored card credentials for subscription services, SaaS platforms, and digital content.

But again, the limit is incentives. Consumers will compare bank-based recurring payments with credit-based options that provide rewards or dispute rights. Merchants must assess where bank-based subscriptions offer net benefit without increasing churn or friction.

What merchants must understand in 2026

P2P payments in commerce are not a magic cost reduction lever. They are not a universal card replacement. They are not fraud-proof.

They are powerful in the right context. They excel in markets where financial inclusion and digital transformation coincide. They perform well in bill payments and high-trust environments. They offer structural cost advantages where incentives are aligned.

But they require careful integration into a broader payment strategy. As Daniel summarised, the future is “more integration than replacement.” Cards, bank rails, wallets, and emerging technologies will coexist. The digital economy is expanding, and multiple rails can grow simultaneously.

The question for merchants is not whether to accept P2P payments. It is how to position them intelligently within a diversified payment stack.

The role of payment orchestration

If you operate across regions, you may need to support Pix in Brazil, UPI in India, RTP in the US, SEPA Instant in Europe, alongside cards and wallets everywhere.

Each rail has different risk dynamics, settlement behaviour, refund mechanics, and customer incentives. Managing that complexity manually is not sustainable.

Payment orchestration allows merchants to integrate domestic P2P rails, cards, and alternative payment methods through a unified layer. It enables routing logic based on geography and context. It provides visibility across settlement types. It supports gradual experimentation without full-stack rewrites.

P2P payments in commerce will continue to grow. But growth alone does not guarantee efficiency or profitability.
