Stable News is Lumx's weekly curation dedicated to tracking the major moves in stablecoins, digital infrastructure, and the future of global payments.
The week opened with Mastercard, which processes roughly $9.5 trillion in annual payments, announcing that it will allow issuers and acquirers to settle card transactions directly in regulated stablecoins. This is not a pilot, but an operational option on the global card rail. In parallel, Paybis published data showing that 98% of the stablecoin volume processed by the platform in 2026 already comes from enterprise customers (up from 36% in 2023). Revolut confirmed via Reuters that it will offer stablecoins alongside FDIC-insured accounts at its future US bank. And much more.
Between market developments, technical and legal discussions, and moves across the globe, the ecosystem reinforces how this technology has moved beyond being simply categorized as "crypto" and is now entering the backbone of how the global financial system processes money.
Mastercard enables card settlement in regulated stablecoins
In brief:
Issuers and acquirers can now settle card transactions directly in USDC, PYUSD, USDG, USDP, RLUSD, and SoFiUSD
Intraday, weekend, and holiday settlement, across 8 networks (Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo, XRPL)
First partners: ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei (US and LatAm)
Mastercard announced the expansion of its settlement infrastructure to allow issuers and acquirers to settle card transactions using regulated stablecoins, including intraday settlement on weekends and holidays. The initiative covers USDC (Circle), PYUSD, USDG, and USDP (Paxos), RLUSD (Ripple), and SoFiUSD (the SoFi Bank stablecoin covered in the previous edition), distributed across eight blockchain networks. The rollout begins in the US and Latin America through partnerships with ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei.
The move follows the New York BitLicense that Mastercard obtained in May. Context matters: Mastercard processes roughly $9.5 trillion in annual payments. Allowing part of that rail to settle in stablecoin is an architectural decision about what the next generation of card infrastructure will do with latency, cost, and operating windows. On-chain settlement removes the "banking hours" constraint from the system — it resolves a bottleneck that has been locked since the 1970s to holiday calendars, weekends, and market closing windows.
The market reading is straightforward. Visa already has a stablecoin settlement program with an annualized run rate of $7 billion (up 50% last quarter, across 9 blockchains). Now Mastercard enters with broader scope, more supported stablecoins, and more networks. The two largest card networks in the world have started treating stablecoin settlement as standard infrastructure.
The scenario taking shape is illustrative: SoFi has just become a stablecoin issuer, Mastercard settles in SoFiUSD, and the end user keeps tapping the same card at any merchant. The transformation is happening precisely on the invisible rails behind that familiar gesture.
Paybis: 98% of stablecoin volume now comes from enterprise payments
In brief:
Enterprise volume rose from 36% (2023) to 98% (first 4 months of 2026) of Paybis stablecoin payouts
Stablecoins represented 86% of total crypto volume on the platform in April, vs. 12% in July 2023
McKinsey: global stablecoin payments reached $390 billion in 2025, 60% of which was B2B
Paybis, a crypto exchange and payment infrastructure platform, released a dataset that reinforces findings from other ecosystem reports: B2B payments have consolidated as the dominant use case for stablecoins. In the first four months of 2026, 98% of stablecoin payout volume processed by Paybis came from enterprise customers, up from 36% in 2023. Stablecoins alone accounted for 86% of the platform's total crypto volume in April, compared to 12% in July 2023.
The sectors driving this shift are consistent with other reports. Digital goods, virtual assets, technology, retail/e-commerce, and fintech account for more than 78% of B2B stablecoin activity on the platform. McKinsey, cited in the report, estimates that global stablecoin payments reached $390 billion in 2025, 60% of which was B2B. The market is increasingly consolidating as a space for corporate treasury and procurement infrastructure.
A secondary data point in the report also deserves attention: 22.5% of surveyed companies already use or plan to use stablecoins for international payments within the next 12 months. And there is an interesting perception gap, nearly half of companies still believe a stablecoin transfer takes between one hour and one day, and about a third estimates fees at 3%. In practice, settlements occur in seconds or minutes, with costs generally below 1%. That gap between perception and reality is exactly where the opportunity lies for those building infrastructure. Market education has become an essential part of distribution.
Revolut prepares US bank with stablecoins alongside FDIC-insured accounts
In brief:
Revolut's US bank expected to launch in 2027, with FDIC-insured accounts, multi-currency, stocks, and crypto
Plans to offer stablecoins alongside traditional accounts, per Reuters
Revolut already offers USDT/USDC on cards in other countries; has 75M+ customers globally
Revolut confirmed via Reuters that it will offer stablecoins through its future US bank, expected to launch next year. Revolut's US CEO, Cetin Duransoy, indicated that customers of the new bank will have access to FDIC-insured accounts, multi-currency deposits, stock trading, crypto, and, now confirmed, stablecoins. Revolut filed for a US national bank charter in March, taking a path that replaces its previous strategy of acquiring an existing bank. The initial focus will be retail customers and businesses with international banking needs, particularly those operating across multiple currencies.
Revolut is not new to stablecoins, in other markets, its customers already make card payments using USDT and USDC. The US move is less about the product and more about the vehicle: the federal charter allows it to offer nationally insured banking products under a single regulator, something that would previously have required multiple state licenses. In practice, it is the SoFi and Nubank playbook, international fintechs becoming US banks via federal charter, with stablecoins as a native product at the counter.
The broader reading matters. Over the past 12 months, Nubank, Crypto.com, Circle, Ripple, BitGo, Fidelity Digital Assets, and Paxos have received conditional OCC approvals to operate as national banks or national trust banks. SoFi became a stablecoin issuer directly within its banking app. Mastercard began processing stablecoin settlement. And now Revolut will be the next regulated bank offering tokenized dollars alongside an FDIC-insured account. The map of the US financial system is being redrawn in real time.
NYDFS and European Banking Authority sign MoU for coordinated stablecoin oversight
In brief:
22-page memorandum between NYDFS and EBA for sharing supervisory information on stablecoins
Coordination covers operational or financial crises at issuers, and civil and criminal investigations
The stablecoin market is already at ~$314 billion and clearly crosses regulatory borders
The New York Department of Financial Services (NYDFS), the regulator best known for its BitLicense regime, and the European Banking Authority (EBA) signed a 22-page memorandum of understanding to coordinate stablecoin supervision between New York and the European Union. The scope covers the exchange of supervisory and confidential information, sharing of insights on civil and criminal investigations, and, perhaps most importantly, coordinated response protocols in the event of "serious operational or financial difficulties" at supervised issuers. If something undermines an issuer on one side of the Atlantic, the regulator on the other side will be notified quickly.
Relevant context: stablecoins have crossed the $314 billion market cap mark and operate at genuine transatlantic scale. When USDC briefly lost its peg in 2023 (dropping to $0.87 following Circle's exposure to Silicon Valley Bank), the event was American in origin but had global repercussions within seconds. The NYDFS-EBA MoU formally acknowledges this reality, it is no longer possible to supervise stablecoins as a local product. The agreement is not legally binding, but it establishes supervisory communication infrastructure that matters: when the New York regulator and the EU regulator have a direct channel, the response time between problem detection and coordinated action shrinks significantly.
The reading for those building infrastructure is instructive. Transatlantic supervisory coordination is institutional maturation of the market. When stablecoins become part of global payment infrastructure, it follows that national regulators begin operating as coordinated regulators. This has existed for decades in banking via Basel and in securities via IOSCO. Stablecoins are now entering the same track. In parallel, it is worth noting that the ECB remains cautious (Isabel Schnabel mentioned "run risks" and concerns about European monetary sovereignty during the week), but the direction emerging is less one of containment and more one of coordinated governance. For issuers and fintechs operating across multiple jurisdictions, this means compliance becomes even more central, and even more predictable.
US Congress debates whether the government should pay tax refunds in stablecoins
In brief:
NCUA Chairman Kyle Hauptman suggested government payments (refunds, stimulus) in stablecoin at a June 4 hearing
Representative Brad Sherman (D-CA) pushed back, calling it "sanctifying an alternative to the dollar"
FDIC announced it will soon propose KYC rules for stablecoin issuers under the GENIUS Act
At a House Financial Services Committee hearing, National Credit Union Administration Chairman Kyle Hauptman suggested that the US federal government could distribute payments via stablecoin — tax refunds arriving on a Sunday or holiday, emergency stimulus delivered "in a more timely and secure manner." The argument is precisely the 24/7 settlement without dependence on the banking calendar. The response came from Representative Brad Sherman (D-CA), a longstanding crypto critic, who pushed back: government payments in stablecoins would "sanctify an alternative to the dollar designed to facilitate a tax evasion economy."
The point deserves careful analysis, as it is the kind of debate likely to recur. On one side, there is a concrete operational advantage, continuous settlement, no banking window dependency, particularly useful in emergencies. On the other, there are concerns about tax traceability, even accounting for blockchain's inherent traceability. What is productive in the debate is that both sides, in practice, acknowledge the product: no one is saying stablecoins won't exist or aren't in use. The discussion is about whether the government itself should adopt it as an official rail. It is a disagreement about integration, not legitimacy.
In a parallel thread at the same hearing, FDIC Chairman Travis Hill announced that the agency will "soon" propose customer identification rules for stablecoin issuers under the GENIUS Act. Falcon Finance launched fUSD with Anchorage Digital as a GENIUS-compliant token. And on a parallel front, the question of yield loopholes in the CLARITY Act resurfaced, Sherman warned that "the best lawyers in the country are already hunting for loopholes" on paying interest on stablecoins. The US regulatory picture continues adjusting in real time as new products emerge.
Worth Reading
Spyglass published an analysis that cuts past the headline: "Chat is dead", according to a senior OpenAI executive.
M.G. Siegler comments on a Financial Times report about what is being described as the biggest ChatGPT redesign since launch. The direction OpenAI is signaling is a move from chatbot to agentic assistant that executes tasks, coding (via Codex), image generation, integration with partners like Canva and Booking. The strategic premise behind the move: Anthropic surpassed OpenAI in top-line revenue despite Claude consuming far fewer resources, and ChatGPT just hit 1B MAU, a large number, but reached 6 months behind target. OpenAI is preparing for an IPO and needs a product that justifies recurring revenue.
The parallel with stablecoins is relevant. There is a product layer that appears to be the final destination (the "chat," the "USDT on the exchange") but that in practice is just the entry point to the real agentic infrastructure beneath. When Alex Embiricos, OpenAI's head of enterprise product, says that "when we have AGI, there will probably be a single entity I talk to that can do whatever I need," he is describing the same kind of unification seen in payments: each separate product (bank, broker, wallet, exchange) becoming a single financial entity coordinated by agents via stablecoin.

Story of the Week
David Kaye published a short but sharp essay on how culture is being consumed at an ever more compressed pace.
The trigger is specific: Chemical Brothers released "Go" in 2015. It passed largely unnoticed at the time. Ten years later, in April 2026, Netflix released the film Apex with Taron Egerton. In one scene, the character puts "Go" on the radio and breaks into a bizarre impromptu dance. The dance became a meme. The song surged 429% on Spotify in a single week and returned to the UK top 10 for the first time in over two decades. Five weeks after the film's release, the band had already shipped a greatest-hits collection titled Go: Apex And Beyond, pushed straight to the Release Radar of Spotify users.
Kaye's point is that a greatest hits collection used to mark the end of a career, the artist looked back at the body of work in retrospect. The documentary came years after the event, once the meaning had settled. Today, the collection arrives at the peak, five weeks into the meme. The documentary arrives during the trial, with pre-made versions ready for any verdict. As he puts it, "much of our culture now is planted ten minutes in the past." The industry responds to attention at the speed of attention. The side effect is that nothing gets understood, nothing ends, everything just loops and gets resold while it's still happening.
The reflection applies to several domains, including the stablecoin ecosystem. Weekly curation is an exercise in stepping back from those ten minutes in the past, in trying to understand what just happened before the next news cycle sweeps the memory clean. Much of the work is not discovering the new, it's keeping the old visible long enough to understand what it means.
