The Payments Pulse: The Payments Infrastructure Shift Is No Longer Theoretical

Four stories defined the payments week. The White House moved to redraw the rules of access to the US payment system, directing the Federal Reserve to open its master account framework to fintech and crypto firms for the first time. Google made the most consequential bet yet on agentic commerce by embedding Klarna and Affirm inside Gemini and AI Mode, wiring BNPL directly into the discovery-to-purchase loop. National Australia Bank completed the acquisition of Banked, signalling that A2A payments are no longer an experiment but a mainstream infrastructure investment for tier-one banks. And Adyen and SAP collapsed the enterprise commerce stack into a single native integration, eliminating the fragmented gateway architectures that have burdened large retailers for years. The direction of travel across all four is the same: the infrastructure layer is consolidating, and access to core payment rails is being renegotiated from the ground up.

The White House Orders the Fed to Open the Rails. The Access Question Just Became a Policy Question.

On May 19, President Trump signed an executive order titled “Integrating Financial Technology Innovation Into Regulatory Frameworks,” directing the Federal Reserve and other financial regulators to review rules that restrict fintech and crypto firms from accessing the US payment system. The order instructs the Fed to evaluate its framework governing access to Reserve Bank payment accounts and services, explore options for extending master account access to non-bank financial companies, and clarify whether individual Federal Reserve banks have independent authority to grant or deny applications. Agencies have 90 days to identify restrictive rules and 180 days to take concrete steps toward reform.

The practical implication is direct: master accounts are the gateway to Fedwire, FedACH, and the core US settlement infrastructure. Firms without them must route through intermediary banks, adding cost, latency, and counterparty dependency into every transaction. The order also directs the SEC, CFTC, and OCC to identify regulations that “unduly impede fintech firms from entering into partnerships with federally regulated institutions” and to streamline charter application processes. The Federal Reserve has already begun moving in this direction. The Kansas City Fed approved a limited-purpose account for Payward, Kraken’s parent company, in March 2026, under a framework that restricts intraday credit but allows direct payment system access. That approval was the first of its kind for a crypto-native firm and now sits alongside a broader public comment process the Fed opened on special-purpose payment accounts on the same day the executive order was signed.

For operators building on the assumption that crypto-native and fintech payment infrastructure will remain permanently separated from core US rails, that assumption is now under active regulatory revision. The 90-day review window means the framework governing master account access will be materially clearer by August 2026.

For compliance teams and operators with US payment infrastructure exposure: The access question that has constrained stablecoin issuers, crypto exchanges, and non-bank payment platforms for years is now a formal policy review with a defined timeline. Operators should be mapping their dependencies on intermediary banking relationships now and modelling what direct rail access would mean for their cost structure and settlement speed. The platforms best positioned to capture the upside of a more open access framework are those already operating with flexible, multi-rail orchestration infrastructure that can adapt as new access pathways are confirmed rather than retrofitting after the fact.

Google Wires BNPL Into Gemini and AI Mode. The Checkout Button Is Moving Upstream.

On May 12, Google confirmed simultaneous partnerships with Affirm and Klarna to embed both providers’ pay-over-time options inside Google Search’s AI Mode and the Gemini app via Google Pay. The integrations are built on Google’s Universal Commerce Protocol, the open standard the company introduced in January 2026 to standardise the full shopping journey – discovery, comparison, purchase, and post-purchase – within conversational AI environments. At checkout, US users shopping through Google surfaces will see Affirm and Klarna alongside standard payment options within Google Pay, with real-time eligibility checks and full payment schedule disclosure before any transaction is confirmed. Affirm has also developed an early BNPL extension for UCP independently, making pay-over-time logic machine-readable for any AI agent operating on the protocol.

The commercial logic is significant. BNPL providers have spent years competing for placement at the bottom of ecommerce checkout pages, after purchase decisions had already been made. Moving into Gemini and AI Mode places them at the moment of discovery and comparison, where the decision to buy and the decision to finance are collapsing into a single conversational step. Klarna cited internal data showing AI-referred shopping traffic in the US grew sharply over the past year as conversational tools took a larger role in product research. At Google Marketing Live on May 20, the company expanded the UCP framework further: adding hotel booking and food delivery as verticals, extending geographic rollout to Canada, Australia, and the UK in coming months, and deepening integrations with major retail partners including Nike, Walmart, and Sephora. The signal from both announcements is that Google’s UCP is becoming the commercial architecture for AI-driven shopping at scale, and that flexible payments are being treated as infrastructure within that architecture, not an optional add-on.

For payment operators and consumer finance platforms: The integration of BNPL into AI-driven commerce environments is not a distribution story – it is an infrastructure positioning story. Affirm’s decision to develop a UCP extension independently signals that providers who want to be present in agentic commerce flows will need to make their payment logic machine-readable and protocol-compatible, not just available at checkout. Operators managing consumer payment products should be evaluating their UCP and agentic commerce readiness now. The volume of AI-assisted purchase decisions is growing faster than most product roadmaps anticipated.

NAB Acquires Banked. A2A Payments Just Became Tier-One Infrastructure.

National Australia Bank completed the acquisition of Banked, a London-founded Pay by Bank and account-to-account payments platform, on May 14. Financial terms were not disclosed. NAB had been a long-term investor in Banked through its venture capital fund, NAB Ventures, participating in three funding rounds across 2022, 2023, and 2024, and had been deploying Banked’s technology commercially for its business clients since 2024. In January 2025, the two companies partnered to enable Pay by Bank at checkout on Amazon’s Australian storefront. The acquisition brings Banked’s full product and engineering capability inside NAB’s infrastructure, with integration into NAB’s technology environment planned over the coming months.

Banked’s platform enables real-time account-to-account payments that allow merchants to receive funds directly from a customer’s bank account, bypassing card network intermediaries. The economics are straightforward: lower transaction costs for merchants, faster settlement, and a checkout flow that eliminates the card rails entirely. Banked’s orchestration platform had been deployed by Bank of America, Citi, and FIS prior to the acquisition, giving it a footprint that extends well beyond its Australian deployment with NAB. NAB’s group executive for transformation framed the acquisition as part of a broader shift in Australia’s payments landscape toward real-time, A2A options that sit alongside cards and digital wallets, rather than replacing them.

The deal is structurally significant for the same reason the Paymentology investment was significant last week: a tier-one bank making a full acquisition of A2A infrastructure is a different signal than a minority venture investment. It marks the point at which Pay by Bank moves from a competitive differentiator being explored by forward-looking operators to a capability that major banks are willing to own outright and integrate into their core platform.

For operators and merchants evaluating A2A payment adoption: The NAB-Banked deal is a useful marker for where the A2A conversation has moved. A year ago, Pay by Bank was a story about cost reduction for high-volume, digitally native merchants. It is now a story about tier-one banking infrastructure investment. The question for operators is not whether A2A becomes material but how quickly the merchant-side incentives shift as more banks offer it natively. Platforms with flexible payment orchestration that can route across A2A and card rails based on cost and conversion data are better positioned to take advantage of that shift than those locked into single-rail architectures.

Adyen and SAP Launch Unified Payment. The Enterprise Gateway Era Is Ending.

On May 13, Adyen announced a deepened collaboration with SAP to support the launch of SAP Unified Payment, a natively embedded payment solution integrated directly into SAP Commerce Cloud. The integration connects digital storefronts to enterprise financial infrastructure without relying on third-party payment gateways. It spans ecommerce, point of sale, and ERP environments, with a direct link to SAP S/4HANA that provides real-time settlement visibility and automated reconciliation across channels. The AI layer is built on Adyen’s transaction network, trained on over a trillion dollars in global transaction data, and is used for both authorisation routing optimisation and fraud management. The target is the specific operational problem that large global retailers face: managing a patchwork of local banks, separate processors, and disconnected fraud tools that creates manual reconciliation burdens, data inconsistencies, and measurable revenue loss.

The significance of the deal is architectural rather than transactional. SAP Commerce Cloud is the enterprise commerce backbone for a significant portion of the world’s large retailers. Embedding Adyen’s payment infrastructure natively into that environment – as a first-party capability rather than an integrated third-party gateway – changes the unit economics of enterprise payment operations materially. Reconciliation that currently requires manual processes across multiple systems becomes automated. Authorisation routing that currently sits outside the ERP becomes a native function with direct access to ERP data. Fraud tooling that currently operates in isolation from the commerce and settlement record becomes part of the same data environment. SAP’s chief product officer for customer experience described the goal as making payments an inseparable part of the enterprise software stack rather than a structural layer that exists alongside it.

For enterprise commerce teams and payment operations leaders: The Adyen-SAP launch is part of the same consolidation story that Adyen’s acquisition of Talon.One in the loyalty segment represents. The direction of enterprise payment infrastructure is toward fewer integration points, not more. For operators currently managing fragmented gateway architectures across multiple markets, the case for consolidation – and the approval rate and reconciliation benefits it enables – is becoming harder to set aside. The question is not whether to consolidate but how to sequence it without disrupting live payment flows.

The Bottom Line

Four stories, one structural direction. Access to core US payment rails is being renegotiated at the regulatory level, and the outcome will determine which players can operate as infrastructure rather than as a layer on top of it. The shopping interface is converging on conversational AI, and the payment providers who treat that as a protocol problem rather than a distribution problem are already ahead. A2A payments have crossed the line from fintech experiment to tier-one banking acquisition. And the enterprise commerce stack is collapsing from a set of integrated third-party tools into a single native platform.

The common thread is not disruption. It is maturity. Each of these moves represents an industry that has finished debating whether a capability is viable and started executing on who owns it. For payment operators, the question that comes out of this week is the same one it has been for the past several months: does your infrastructure give you the routing flexibility, protocol compatibility, and rail access to move as these markets move – or does it require a rebuild each time the landscape shifts? The gap between those two positions is widening.
