How EU Instant Payments is Reshaping Finance Infrastructure

The EU's instant payments mandate sets clear deadlines: banks have been required to receive instant payments since January, with sending capabilities due by October 2025. 

Yet behind these straightforward regulatory requirements lies a more complex transformation that extends well beyond technical compliance.

While institutions focus on meeting the mandated timeframes for real-time transfers, the operational implications run much deeper than upgrading payment systems. 

The shift to instant settlement is forcing fundamental changes to fraud prevention, business models and the very architecture of how banks operate.

The 24/7 challenge banks didn't see coming

Meeting deadlines is one thing; running a bank round the clock is quite another. 

Rossana Thomas, Vice President Enterprise Payments at Fiserv, says that “adapting comprehensively rather than tactically to the regulatory push will position institutions to meet evolving market expectations efficiently and effectively”.

The infrastructure demands extend well beyond upgrading payment rails. Banks are discovering they need entirely new operational frameworks for continuous processing, real-time customer support, and always-on fraud monitoring. 

Legacy systems built for business-hour operations now must handle weekend millionaire transfers and middle-of-the-night merchant settlements.

Laurent Descout, Founder and CEO of Neo, highlights an often-overlooked consequence of the regulatory changes. With the previous €100,000 limit removed, “it's now possible to transfer millions overnight.” 

Banks that once managed liquidity during predictable business hours now face the prospect of massive fund movements at 3am on a Sunday.

This creates what Rossana describes as a “two-pronged approach: prioritising regulatory compliance while modernising backend systems, including cloud migration and real-time fraud monitoring.” 

Modern payment hubs are emerging as the solution, separating payment execution from creaking core systems. These platforms promise what Rossana calls the ability to “aid institutions in meeting regulatory timelines, ensuring real-time orchestration, settlement, built-in compliance and payment flow visibility”. 

But implementing such systems requires more than technology: it demands operational transformation that many banks are still grappling with.

Fraud prevention in the age of 10-second transfers

Traditional fraud prevention looks quaint in the instant payments era. Banks spent decades building elaborate post-transaction monitoring systems, analysing patterns over hours or days to spot suspicious activity. With 10-second settlement windows, that approach has become obsolete.

The technological response involves deploying machine learning models that can assess risk in milliseconds. 

Top-tier institutions are integrating behavioural biometrics to detect unusual user patterns, alongside dynamic scoring engines that adjust based on live context. These systems run at the network edge to eliminate processing delays entirely.

Irene Skrynova, Chief Customer Officer at Unlimit, explains the transformation: “The nearly instant settlement window dictates a paradigm shift in risk management. Traditional post-transaction screening is obsolete; the new standard is AI-driven, preemptive fraud prevention.”

Machine learning models now make instant go-or-no-go decisions at the transaction layer, often processing logic directly on payment gateways or even user devices.

But regulatory frameworks haven’t adapted to this new reality. Laurent acknowledges the operational challenges this creates, noting that “instant payments may move money in seconds, but managing fraud and risk at that speed is a whole new challenge.” 

Current anti-money laundering requirements still assume institutions can perform comprehensive due diligence within 10-second windows – an expectation that may need recalibrating.

Banks are implementing new tools to bridge this gap. Confirmation of Payee and IBAN-name matching help catch impersonation fraud before transfers complete. 

Meanwhile, AI systems process contextual signals like location, device fingerprints, and transaction history to learn normal user patterns and flag suspicious deviations without generating excessive false positives.

When speed becomes free, what do you sell?

The EU’s pricing parity requirement eliminated the most obvious revenue model for instant payments. Banks can no longer charge premiums for speed, forcing a complete rethink of how payment services generate value.

The response has been to shift focus from the transaction itself to the broader customer experience. 

Smart institutions are bundling instant payments into comprehensive service packages, monetising enhanced customer journeys rather than individual transfers. 

This includes services like instant payroll systems, real-time expense reimbursements and immediate refund processing – capabilities that use instant rails as enablers rather than end products.

Irene describes the transformation: “When speed becomes free, experience becomes the product. Payment providers can no longer rely on just monetising the transaction itself. 

“Value creation now has to come from the experience layer, with what happens before, during, and after a transaction.”

Fiserv’s approach exemplifies this shift. Rather than simply accelerating payment processing, their platform enables banks to embed financial services deeper into business workflows and customer interactions. 

Rossana explains how the platform helps institutions “enhance their services on instant rails. By offering valuable services like instant payroll and improved automation, EPP helps institutions progress towards embedding financial services more deeply into business workflows and customer interactions.”

The long-term economics also look compelling. 

Laurent points to cost efficiencies that emerge over time: “In the long term, although investing in instant payment infrastructure is costly, banks and payment service providers will benefit from greater cost efficiency through lower transaction, handling and operational expenses, as well as improved liquidity management.”

Competition is moving toward premium API offerings, advanced analytics, and orchestration services. The winners will be those who make instant transfers seamless components of superior customer experiences.

The platform revolution

Variable Recurring Payments, API-driven services and embedded finance are converging to reshape how payment services actually reach customers. 

The old model – where banks owned the entire customer journey – is crumbling.

Irene says that institutions “can't operate in silos anymore.” The leaders are building developer-first platforms that abstract complexity, enabling partners to create new payment flows without understanding the underlying infrastructure. 

“This is about composability, extensibility and orchestration – not product proliferation,” she notes.

Laurent describes how payment service providers are “recasting themselves as infrastructure platforms using APIs to power third-party use cases.” 

The transformation extends beyond European borders. Cross-border payments, long plagued by high fees and slow processing, are being revolutionised by modern infrastructure. 

Laurent notes that providers can now address “high fees, slow processing times and limited transparency” through interoperable systems and real-time processing.

Variable Recurring Payments (VRPs) add another dimension, enabling dynamic payment arrangements that move far beyond traditional direct debits. 

Combined with instant settlement, VRPs create new possibilities for cash flow management and customer engagement that were impossible under previous payment frameworks.

The orchestration economy takes shape

Embedded finance has killed the idea that payment providers can own customer relationships. Financial services increasingly live inside other platforms – marketplaces, apps, business software – where the payment experience must be seamless and invisible.

Rossana describes how companies are adapting their infrastructure to be “more modular, API-first and cloud-native to meet the demands of this evolving environment, enabling seamless connections to various payment rails.” 

Fiserv’s platform exemplifies this approach, functioning as a unified hub managing transactions across multiple rails – real-time payments, ACH, cross-border networks – while integrating smoothly into diverse business contexts.

The competitive dynamics are shifting fundamentally. Success no longer comes from owning the customer journey but from being everywhere customers need payment capabilities. 

Irene captures this evolution: “As financial services shift into third-party platforms, marketplaces and apps, traditional payment providers must rethink how and where they deliver value. 

“The days of owning the customer journey are fading; relevance now comes from being everywhere your customer needs you.”

Multi-rail strategies are becoming standard as platforms demand access to every payment method their users might want. 

When every marketplace wants to offer comprehensive payment options, Irene argues: “the key differentiator isn’t technical – it’s how seamlessly your payment partner can manage every method.”
