The Payments Pulse: Access, Infrastructure, and the Stablecoin Tipping Point.

This week the payments industry moved on four fronts simultaneously. Western Union confirmed it is launching a Solana-based stablecoin in May to replace SWIFT for internal settlements, a move that reframes what legacy remittance infrastructure is capable of becoming. The UK government used Fintech Week in London to announce a single regulatory framework covering traditional payments, stablecoins, and tokenised deposits together for the first time. A bipartisan US House bill proposed giving fintechs and regulated crypto firms direct access to Federal Reserve payment rails, removing the bank intermediary layer that has added cost and delay to digital payments for decades. And Mercury became the latest fintech to receive conditional OCC approval for a national bank charter, joining a queue of nearly 20 firms that applied or received approvals in Q1 2026 alone. Five stories, one consistent theme: the structural access question in payments, who can connect to what infrastructure and on what terms, is being answered in real time across multiple jurisdictions simultaneously.

Western Union Is Replacing SWIFT With Its Own Stablecoin. The Launch Is Next Month.

On April 24th, Western Union CEO Devin McGranahan confirmed on the company’s Q1 2026 earnings call that its US dollar stablecoin, USDPT, is in the final stages of preparation and will launch next month. Built on Solana and issued by Anchorage Digital Bank, a federally chartered crypto custody institution, USDPT will not launch as a consumer-facing product. Its first deployment is as an alternative to the SWIFT interbank settlement network that Western Union currently uses to move funds between the company and its global agent network. The company operates in more than 200 countries with over 360,000 cash pickup locations. Replacing SWIFT settlement with on-chain settlement means real-time finality including weekends and banking holidays, and the elimination of capital tied up in transit.

The launch is structured in three layers. USDPT handles internal settlement between Western Union and its agents. The Digital Asset Network, or DAN, connects crypto wallet providers to Western Union’s retail and agent infrastructure through a single API, allowing wallet users to convert digital assets into local currency through Western Union’s existing network. The first DAN partner went live this week. Seven more are expected to activate by year end. The third layer is the Stable Card, a consumer-facing prepaid card built with Rain and Visa that allows customers to hold USDPT and spend it globally, with a particular focus on inflation-sensitive markets where dollar-denominated value has immediate practical utility.

McGranahan was direct about the strategic motivation: Western Union intends to own the economics linked to stablecoins rather than pay them to a third-party issuer. Revenue from issuance, exchange spreads, transaction fees, and float on reserves that currently flow to external stablecoin providers will flow to Western Union under this architecture. The company is not the only legacy player building on Solana for this reason. PayPal’s PYUSD, Fiserv’s FIUSD, and DoorDash via Stripe’s Tempo chain have all made similar moves. Solana processed a record $650 billion in stablecoin transactions in February 2026 alone, making it the dominant enterprise stablecoin settlement network by volume.

For cross-border payment operators: When a 175-year-old remittance company with 360,000 cash-out points replaces SWIFT with a Solana-based stablecoin, the conversation about whether stablecoin rails are ready for enterprise-scale settlement is over. The question now is how quickly the rest of the industry builds the multi-rail architecture to route across both legacy and stablecoin infrastructure depending on corridor economics, speed requirements, and counterparty capabilities. The case for building that architecture now rather than in response to competitive pressure is covered in our piece on why multi-PSP strategies and payment orchestration are no longer optional in 2026.

The UK Announced a Single Regulatory Framework for Traditional Payments, Stablecoins, and Tokenised Deposits.

On April 21st, the UK government used Fintech Week in London to announce a comprehensive package of payments regulation reforms that bring traditional payment services, stablecoins, and tokenised deposits under a single, unified framework for the first time. The package was presented by City Minister and Economic Secretary to the Treasury Lucy Rigby and marks the most significant shift in UK payments regulation since the introduction of the Payment Services Regulations in 2009.

The headline measure is a planned consultation on reforming payment services and electronic money regulation to create a coherent single framework that covers both fiat and tokenised payment instruments. The framework will bring stablecoins issued under the forthcoming UK regulated stablecoin issuance regime into the payments regulatory perimeter alongside traditional e-money and payment institution structures. The government also confirmed it will explore how payment services regulation should evolve to account for payments conducted by AI agents, making the UK the first major jurisdiction to explicitly commit to an AI agent payments regulatory workstream. The FCA will receive new powers over the next phase of Open Banking, supporting new payment products within commercial schemes.

The government also appointed Chris Woolard, a partner at EY and former interim CEO of the FCA, as Wholesale Digital Markets Champion. Woolard will lead the development of a tokenised wholesale financial markets ecosystem, coordinating across the public and private sector. Legislation to reduce administrative burdens for stablecoin payments firms is being brought forward separately, addressing a specific pain point where firms currently need authorisation under both crypto and payments regulations simultaneously during the transition period.

For operators with UK exposure: A unified framework covering fiat and tokenised payments under a single regulatory regime removes one of the most significant compliance complexity barriers to building stablecoin products alongside traditional payment services in the UK. The AI agent payments workstream is the more forward-looking signal. The UK is explicitly building its regulatory infrastructure for agentic commerce now, ahead of formal requirements. The operators mapping their compliance architecture in parallel are building the foundation that will make licensing straightforward when the consultation concludes. Our analysis of how stablecoin regulation has evolved and what a compliant stablecoin now requires provides the foundational context for understanding where the UK framework sits in the global regulatory landscape.

A Bipartisan US Bill Would Give Fintechs Direct Access to Federal Reserve Payment Rails.

On April 21st, US Representatives Young Kim, a Republican from California, and Sam Liccardo, a Democrat from Silicon Valley, introduced the Payments Access and Consumer Efficiency Act, known as the PACE Act. The bill proposes a federal pathway for qualified nonbank payment providers to connect directly to Federal Reserve payment infrastructure including Fedwire, the FedNow instant payment service, and FedACH, without routing transactions through intermediary banks. Under current rules, nonbank payment companies must work through sponsor banks to access Fed clearing systems, and those intermediaries charge markups of up to 100 times the Fed’s own per-item fee, according to the bill’s fact sheet.

To qualify, a firm must hold at least 40 active state money transmitter licences, which effectively targets large-scale operators already regulated across most US states, or hold a state bank or credit union charter. Qualifying firms could register for an optional federal framework administered by the Office of the Comptroller of the Currency, receive a payments reserve account at a Federal Reserve bank, and connect directly to clearing and settlement infrastructure. The OCC would have six months to decide on completed applications, with an automatic approval mechanism if that deadline is missed. Capital and operational requirements are set at bank-like levels, with 1:1 reserve backing and Bank Secrecy Act compliance standards aligned to the GENIUS Act.

The bill has no Senate companion legislation yet. A Senate discussion is underway and the Blockchain Association and the Financial Technology Association both issued immediate support statements. Traditional bank trade groups are expected to push back at committee, as the bill structurally reduces banks’ role as intermediaries in digital payments and removes a significant fee revenue stream. Whether it passes in its current form or not, the PACE Act signals that the political consensus around fintech access to federal rails has shifted materially in 2026.

The structural implication: Direct Fed rail access for fintechs would change the cost architecture of digital payments in the US fundamentally. It would reduce sponsor bank dependency, compress intermediary fees, and allow payment platforms to build tighter, faster settlement loops without a bank in the critical path. For operators currently absorbing intermediary costs on ACH and instant payment flows, the PACE Act trajectory is worth monitoring closely even before it reaches a Senate vote. The broader context for how real-time rail access connects to approval rate and payment performance is covered in our analysis of approval rates as the real growth lever in digital payments.

Nearly 20 Fintechs Applied for or Received OCC Charters in Q1 2026. The Queue Is Now a Market Signal.

Mercury received conditional OCC approval on April 27th to establish Mercury Bank, N.A., a full national bank that will allow the fintech to deliver banking products to its 300,000-plus customers under direct federal oversight. Mercury applied for the charter in December 2025. The OCC processed the application in under five months, consistent with Comptroller Jonathan Gould’s stated goal of turning around charter applications within 120 days. Mercury’s approval follows Coinbase’s conditional OCC approval on April 2nd for a national trust bank. Agora Finance applied for a national trust bank charter on April 24th for stablecoin issuance and digital asset custody.

The American Banker reported this week that nearly 20 neobanks, digital asset companies, lenders, and payment providers applied for or conditionally received OCC charters in Q1 2026 alone. That figure, combined with the OCC’s stated 120-day processing target and the current administration’s explicitly receptive posture toward fintech charter applications, creates a regulatory environment that PitchBook has described as a now-or-never moment. Trust charters in particular have accelerated following the GENIUS Act, which created a clear federal licensing pathway for stablecoin issuers that trust bank status can satisfy.

For Mercury specifically, the charter enables direct Zelle integration into its accounts, expanded lending products for both businesses and individuals, and the ability to build proprietary payment infrastructure rather than relying on partner bank rails. Mercury will continue operating with its existing partner bank arrangements while satisfying remaining OCC, FDIC, and Federal Reserve requirements. Jon Auxier, who previously led SoFi’s national bank charter implementation, will serve as CEO of Mercury Bank.

What the charter queue means for operators: When nearly 20 fintech and digital asset firms are in the OCC charter process simultaneously, and the regulator is processing applications within 120 days, the legal and regulatory infrastructure for non-bank entities to operate as payment and custody institutions at federal scale is being built in real time. The platforms that understand what charter status changes about product capability, specifically direct rail access, qualified custodian status, and the elimination of sponsor bank dependency, are the ones building product roadmaps that account for this shift. Our coverage of the OCC rulemaking and what regulated stablecoin status now requires is the relevant read for operators assessing how the charter landscape affects their own infrastructure decisions.

Nuvei Launches Direct Acquiring in Mexico. Local Performance in Global Commerce Gets Another Data Point.

On April 21st, Nuvei announced the launch of direct acquiring in Mexico, enabling businesses to process card transactions locally through Nuvei’s own licensed infrastructure. The launch extends Nuvei’s direct acquiring footprint to 52 markets, covering 200-plus countries, 150 currencies, and more than 720 alternative payment methods. Phil Fayer, Nuvei’s Chair and CEO, summarised the operating philosophy directly: commerce is global but payment performance is local. The company describes its strategy as building infrastructure inside domestic payment ecosystems rather than routing transactions across borders, which improves approval rates, increases transaction data visibility, and reduces operational complexity for merchants managing payments across markets.

Mexico is a market where the performance gap between local and cross-border acquiring is significant. Local card processing in Mexico operates through domestic schemes and acquiring relationships that carry materially higher authorisation rates than cross-border processing for the same transaction. For businesses selling to Mexican consumers, the practical impact of switching from cross-border to local acquiring can be a double-digit improvement in approval rates, which translates directly into revenue that would otherwise be declined and lost. Nuvei’s direct acquiring launch removes the need to establish and manage a separate local acquiring relationship for merchants operating on its platform.

The timing is also worth noting in the context of the tariff environment. US tariff measures have created uncertainty in some US-Mexico trade corridors, but consumer e-commerce flows between the two markets are structurally robust. Mexico represents one of the highest-growth e-commerce markets in Latin America, with mobile commerce particularly strong. A direct acquiring presence there positions Nuvei to capture volume in a market where payment infrastructure quality directly determines merchant competitiveness.

For operators running cross-border e-commerce volumes into Latin America: The local acquiring story in Mexico is the same story playing out in Brazil, Colombia, Indonesia, and every high-growth consumer market where cross-border acquiring underperforms local rails. The merchants capturing that performance differential are the ones who have built the orchestration layer to route to local acquirers when available, not the ones locked into a single cross-border gateway. Our analysis of approval rates as the real growth lever in digital payments covers the mechanics of how local acquiring, smart routing, and approval rate optimisation compound into meaningful revenue differences at scale.

The Bottom Line

This week’s five stories share a single structural argument. The access question in payments, who can connect directly to infrastructure, on what regulatory terms, and through what rails, is being answered simultaneously across legacy remittance, US congressional legislation, UK government policy, fintech charter queues, and local acquiring infrastructure in emerging markets.

Western Union is replacing SWIFT with its own Solana stablecoin. The UK is unifying its payments regulatory framework across fiat and digital. A bipartisan US bill is proposing direct Fed rail access for fintechs. Nearly 20 fintech firms have applied for or received OCC charters in Q1 2026. And Nuvei is building local infrastructure inside one of the most important e-commerce markets in Latin America. Every one of these stories is about a different entity removing an intermediary, a regulatory barrier, or a geographic limitation from their payment infrastructure.

The operators who will compete most effectively in this environment are not the ones waiting to see which of these initiatives passes, launches, or scales. They are the ones building modular, multi-rail, API-first infrastructure now, so that when any of these access points opens, they can route through it immediately. The window to build that architecture ahead of competitive pressure is narrowing every week.
