Stablecoin Remuneration and the U.S. Regulatory Framework

In this special edition of my daily digest I’ve prepared a summary of the issues around remunerated stablecoins in the U.S. regulatory context that started with the enactment of the GENIUS Act in July 2025, which prohibited stablecoin issuers from paying interest or yield to holders but is silent on whether affiliates or third-party platforms may offer equivalent rewards — a gap the crypto industry has moved quickly to exploit. The Office of the Comptroller of the Currency (OCC) February 2026 implementing rulemaking proposes to close this administratively by extending the prohibition to affiliates and related third parties, but that rule is not yet final. The CLARITY Act, the broader digital asset market structure bill that passed the House in July 2025 but is still making its way through the Senate, has become the primary legislative vehicle for resolving the question. The most recent draft has introduced a prohibition of yield on passive holdings while permitting activity-linked rewards, but it remains to be seen if this will get it through Senate Banking Committee and on to the Senate floor for a vote.

(Scroll down past this summary for some regularly scheduled central bank digital currency (CBDC) developments.)

The Banking Industry’s Case Against Stablecoin Remuneration

The banking industry’s core argument, advanced primarily by the American Bankers Association (ABA) and the Bank Policy Institute (BPI), is that yield-bearing stablecoins would erode bank deposits and, by extension, reduce the credit available to households and businesses (Nelson, 2026). The theoretical anchor is a family of general equilibrium models which show that a digital payment instrument offering yield can displace bank deposits and contract lending if its rate exceeds a certain threshold (Chiu et al., 2023). Research, funded by Coinbase, Paradigm, PayPal, and Stripe, adapted this framework to argue that current stablecoin reward levels fall within a “safe zone” that enhances rather than damages bank intermediation by forcing deposit repricing (Cong, 2026). Nelson (2026) turned the Cong (2026) model against itself, the paper implies that once stablecoins reach projected 2030 scale, dollar-for-dollar deposit destruction and significant lending contraction follows. Wang (2025) estimates that such lending contraction could be between $65 billion and $1.26 trillion depending on adoption scale, reserve management, and whether issuers gain Federal Reserve master account access.

However, two caveats are warranted:

  • The Chiu et al. (2023) framework was designed to model a central bank digital currency — a sovereign instrument set by a welfare-maximizing authority with a single rate and a financial stability mandate. Transposing it to a competitive stablecoin market, where multiple private issuers face profit incentives and no coordination mechanism, important assumptions that do not hold. The central bank in that framework can target the “sweet spot” of beneficial competition precisely because it internalizes systemic consequences; a private stablecoin issuer — or more precisely, the exchange intermediaries passing reserve income through to holders via subscription models and loyalty programs — faces no equivalent constraint.
  • Wang (2025) does not model whether competitive deposit repricing could generate the crowding-in effect that Chiu et al. (2023) identify — i.e., whether banks raising deposit rates in response to stablecoin competition might expand intermediation sufficiently to offset or reverse the deposit migration. She treats the competitive response as a defensive mechanism that partially cushions outflows, not as a mechanism that could produce a welfare-enhancing equilibrium. The paper’s analytical architecture simply takes deposit outflows as directionally given and then traces their consequences for credit provision, without closing the loop through endogenous bank pricing behavior.

Nelson (2026)’s strongest argument points to the Coste (2024) analysis, which shows that even when stablecoin reserves remain within the banking system as deposits, they arrive as wholesale funding subject to 100% liquidity coverage ratio (LCR) outflow rates rather than the 5–10% applicable to retail deposits. The receiving bank must therefore hold equivalent high-quality liquid assets against them, rendering those funds prudentially inert for lending purposes. This mechanism operates regardless of whether aggregate deposit volumes change, and it is mechanical rather than behavioral — meaning it holds even if banks reprice deposits competitively in response to stablecoin competition.

The Affiliate Loophole and Section 404 of the CLARITY Act

Section 404 of the current CLARITY Act draft (“prohibiting interest and yield on payment stablecoins”) reaffirms the GENIUS Act’s core prohibition on issuer-paid yield and attempts to resolve the affiliate loophole question that it left open. It draws a distinction between rewards linked to transaction activity (e.g., paying a stablecoin to a merchant, completing a cross-border transfer) and rewards accruing solely from holding a balance in a digital wallet. The former would be permitted; the latter prohibited. In practice, this mirrors the legal recharacterization already underway in the market, such as Coinbase’s move to restrict USDC rewards to Coinbase One subscribers and its framing of those rewards as a “loyalty program” rather than passive yield. This is the kind of arrangement the most recent draft attempts to legitimize for activity-linked payments while drawing a line against pure balance-based accrual. Whether that line is administratively enforceable, given that the economic substance of near-term Treasury yield pass-through does not change based on how the payment is labelled, remains the central unresolved question.

The Challenge of Fintech Cash Management Products

An analytical tension in the banking industry’s position is revealed by its treatment of fintech cash management products. Platforms such as Betterment currently pay depositors approximately 3.25% annually — close to the federal funds rate — by sweeping customer funds across a network of Federal Deposit Insurance Corporation (FDIC)-insured banks. This model does to branch-based banks’ deposit spreads essentially what the Chiu et al. (2023) mechanism predicts a competitive outside option should do: it forces repricing. Yet when the FDIC proposed in 2024 to tighten the brokered deposit rules that govern these arrangements, which would have subjected fintech sweep products to additional restrictions, the ABA, BPI, and a coalition of nine other trade groups jointly opposed the proposal.

The explanation likely lies in the structure of the banking lobby’s membership. Large banks that anchor sweep networks and receive wholesale deposits via them have no interest in restricting arrangements that benefit their funding base. The stablecoin case is structurally different — reserves held in Treasury bills or at the Federal Reserve bypass the banking system entirely — which is why it generates a unified banking industry response. The banking lobby’s argument implicitly treats the current level of deposit spreads as socially optimal and worth protecting, while simultaneously defending the very competitive mechanisms that have already eroded those spreads for rate-sensitive depositors.

Unresolved Tensions

Several questions remain open regardless of how the drafting process resolves. The activity-versus-passive-holding distinction in Section 404 rests on a legal characterization that may not be administratively stable. If the economic pass-through of reserve income to holders is empirically indistinguishable between the two forms — Krause (2026) found a 98.7% correlation between USDC rewards and Treasury yields — enforcement of the distinction will depend on definitional precision that neither the current legislative text nor the OCC rulemaking has yet provided. The Coste (2024) LCR mechanics apply irrespective of how the yield question is resolved, suggesting that prudential concerns about deposit composition persist even under a complete yield prohibition. The Wang (2025) finding that effects are highly heterogeneous across bank types — with mid-sized regional banks facing the greatest vulnerability — points to a distributional dimension that aggregate models obscure and that community banking advocates have raised without yet quantifying rigorously at the institutional level. Finally, the broader question of whether branch-based deposit spreads reflect productive intermediation or market power against inertial depositors remains analytically unresolved in the policy debate (Zhang et al., 2024). The answer to that question matters considerably for evaluating how much of the banking industry’s concern reflects genuine systemic risk versus incumbent rent protection.

Now on to the regularly scheduled updates…

Digital Shekel Project: Progress Report 2025 (Bank of Israel)

The Bank of Israel published an update on its digital shekel project that is progressing toward an end‑2026 issuance decision, concluding that expected macroeconomic benefits are likely to exceed the associated costs. The analysis found that disintermediation risk is low under appropriately calibrated holding limits, with policy rate cuts and liquidity injections (via short‑term Bank of Israel bill redemptions) sufficient to offset deposit outflows except under extreme scenarios. A decentralized supervisory model is proposed, with existing financial regulators overseeing their respective digital shekel participants under a uniform Bank of Israel rulebook. A unified multipurpose infrastructure for retail and wholesale use is found technologically feasible and preferable to separate systems. Open questions include whether the digital shekel should be remunerated, offline payment double‑spend prevention, and retail‑versus‑wholesale sequencing. In addition, a quantitative survey of small businesses found that only one‑fifth expressed interest in using digital shekels, citing satisfaction with existing digital payment methods, although they indicated general interest in a digital shekel if it were to offer lower fees than current digital payment methods. A qualitative survey of large corporations also found lukewarm interest in using a digital shekel, with respondents mainly viewing it as potentially relevant for internal settlement and treasury operations rather than for customer‑facing retail payments, and stressing the importance of compatibility with existing systems.

BOE DLT Innovation Challenge 2025: Final Report (BOE)

The Bank of England (BOE) reported on explorations, carried out in September–October 2025 with nine firms, to see if wholesale central bank money can be transacted and settled on an external programmable ledger not controlled by the central bank. It concluded that distributed ledger technology (DLT) can technically speed wholesale settlement and improve throughput but only by accepting material trade‑offs in finality, governance, and resilience. Designs that deliver faster, more “deterministic” settlement tend to shift risk and trust assumptions, weakening decentralization or operational robustness relative to established real‑time gross settlement systems. Scalability enhancements add architectural complexity and create new dependencies that interact negatively with control and resilience requirements. Interoperability solutions with other DLT and legacy systems rarely eliminate trust or operational dependencies; instead they reallocate them across networks or third parties, including off‑chain components for permissionless ledgers. Overall, the trials suggest no dominant DLT architecture for wholesale settlement and frame the policy problem as one of choosing which trade‑offs in speed, control, and governance are acceptable. Further targeted DLT experiments are planned for 2026. [BOE]

Crypto-Asset Service Providers as Financial Intermediaries: Risks and Policy Approaches (BIS)

The Bank for International Settlements (BIS) published a paper that argues that large crypto-asset service providers have evolved into multifunction crypto-asset intermediaries performing bank-like risk transformation and should face commensurate prudential regulation. The paper documents expansion from custody and trading into lending, derivatives, and “earn” programs that transform client assets into credit, liquidity, and maturity risks. Such activities replicate core intermediation functions without capital, liquidity, or supervisory safeguards, raising financial-stability and regulatory-perimeter concerns as links to traditional finance deepen. The authors advocate a combined entity- and activity-based approach, while noting unresolved issues around data gaps, cross-border supervision, and incomplete coverage of key activities. [BIS]

The Stablecoin Stumbling Block (FT)

The Financial Times published a paper in which Daniel Heller argues that existing stablecoin designs are structurally unfit to serve as wholesale settlement assets at scale. He notes that post-crisis standards for financial market infrastructures require settlement in central bank money or assets with equivalent credit quality and intraday liquidity, a bar current stablecoin reserve and redemption models fail to meet. This matters because large-value payments and securities settlement depend on systemically robust “money,” and today’s stablecoins embed maturity, liquidity, and operational risks misaligned with that role. Heller sees potential in tokenized central bank money or purpose-built, narrow-balance-sheet wholesale stablecoins, but leaves open whether central banks will grant reserve access and how global oversight would be structured. [FT]

I’m reposting this paper by Christian Pfister because of its relevance to yesterday’s post regarding the European Central Bank’s (ECB’s) stated digital euro motivations:

For a Political Economy of Central Bank Digital Currency (REP)

In this 2024 Revue d’Economie Politique (REP) article, Christian Pfister applies a positive (political economy) rather than normative framework to retail central bank digital currency (rCBDC). He maps stakeholder incentives across governments, central banks, regulators, incumbent banks, and fintech firms, then tests whether stated policy rationales align with those incentives. He concludes that publicly foregrounded motives, like financial inclusion, payment system safety, monetary sovereignty, and privacy, are analytically weak or already reached in developed economies. The dominant but largely unstated drivers are fiscal, such as seigniorage maximization through balance-sheet expansion, permanent rollover of sovereign debt held as rCBDC backing, and reduced tax evasion. Setting rCBDC remuneration at zero, officially framed as “do no harm” to bank intermediation, simultaneously serves those seigniorage objectives while suppressing a monetary policy transmission channel that the academic literature broadly endorses. For institutional design, combining legal tender status with fee exemptions advantages rCBDC in ways that raise competitive-neutrality concerns and risk crowding out private innovation. In non-democratic settings, programmable money creates structural conditions for mass surveillance. [REP]

Eastern Caribbean Central Bank (ECCB) Suspends DCash 2.0 Project (ECCB)

[February 13, 2026] The Monetary Council of the Eastern Caribbean Central Bank (ECCB) approved the suspension of the DCash 2.0 central bank digital currency (CBDC) project to prioritize the development of the fast payment system (FPS) and participation in the The Caribbean Community (CARICOM) Payments and Settlement System (CAPSS) pilot.

ECB Signs Agreements with European Standard Setters to Facilitate Digital Euro Payments (ECB)

The European Central Bank (ECB) announced agreements with three European payment standard‑setting bodies to reuse existing open standards for processing online digital euro payments. The standards include European Card Payment Cooperation (ECPC) CPACE (to support contactless “tap‑to‑pay” payments using near‑field communication between a payment device and a payment terminal); nexo (specifications to connect merchants’ systems with the back-end systems of payment service providers and acquirers; and Berlin Group (to allow payments to be made using an alias (such as a mobile phone number) and support balance checks and reconciliation across mobile devices and payment acceptance in areas like digital euro transactions initiated in merchant apps on smartphones). The deal aims to reduce integration costs, support cross‑border scaling of European schemes, and lessen dependence on proprietary card and wallet standards owned by global firms. This move embeds the project in existing retail payment infrastructure, but leaves open how additional standards and governance will evolve over time. [ECB]

Western Union to Launch Stablecoin Next Month (The Block)

Western Union will launch a Solana-based, U.S. dollar–backed stablecoin called USDPT next month, initially using it as an internal settlement rail with key agents in select countries as an alternative to SWIFT, enabling on-chain cross-border settlement even during traditional banking holidays. The firm is also rolling out a Digital Asset Network (DAN) that connects consumer crypto wallets to Western Union’s retail and agent network so users can cash out digital assets into local currency through familiar outlets, with the first partner going live this week. Later this year, Western Union plans a USD “Stable Card” in dozens of markets, allowing consumers—especially in inflation-prone countries—to hold dollar-denominated value in stablecoins and spend globally. [The Block]

FIDO Alliance to Develop Standards for Trusted AI Agent Interactions (FIDO)

The FIDO Alliance announced a new Agentic Authentication Technical Working Group and payments workstream to standardize how AI agents authenticate, delegate, and execute commerce on users’ behalf. The initiative, building on contributions like Google’s Agent Payments Protocol and Mastercard’s Verifiable Intent, aims to create phishing‑resistant mechanisms for verifiable user instructions, agent authentication, and bounded, user‑controlled delegation for transactions. This matters for policy and market structure because it could harden agentic commerce against fraud, reduce reliance on proprietary stacks, and provide interoperable guardrails around intent, authorization, and liability allocation, while leaving governance and enforcement models still under‑specified. [FIDO]

Reforming MiCA for Euro Stablecoins (Blockchain for Europe)

Blockchain for Europe published a report in which Ulrich Bindseil and Erwin Voloder propose reforms to the Markets in Crypto-Assets Regulation (MiCAR) to bolster euro-denominated electronic money tokens (EMTs). Core recommendations include permitting remuneration limited to reserve income pass-through, eliminating the 30-60% minimum bank deposit requirement to enable diversified high-quality liquid assets (HQLA) akin to liquidity coverage ratio standards, enhancing proportionate reserve transparency via standardized reporting, mandating stress testing and concentration limits, granting calibrated central bank deposit access for safeguarding, and clarifying cross-border multi-issuance frameworks. These adjustments aim to mitigate MiCAR’s regulatory overreach—placing Europe on the downward-sloping Laffer curve for stablecoin competitiveness—while preserving prudential safeguards, reducing bank interdependencies, and elevating the euro’s global on-chain role amid U.S. dollar dominance. [Blockchain for Europe]

A Tale of Transactions: An Analysis of Retail Payments in the Euro Area (JPSS)

The Journal of Payments Strategy & Systems (JPSS) published an article in which Diederik Bruggink uses euro area retail payment data to inform debate on potential holding limits for a digital euro. Drawing on the European Central Bank’s Study on the Payment Attitudes of Consumers in the Euro Area 2024 and ECB statistical data, he derives average transaction values and cash holdings by country, and analyzes card and e‑money transactions by instrument and merchant category. The paper shows cash still anchors small-value payments and backup liquidity, debit cards dominate everyday non‑cash transactions with falling average ticket sizes, and e‑money is highly concentrated in a few markets. This matters because realistic digital euro limits must reflect actual transaction sizes, cross‑country heterogeneity, and the contingency role of cash, or risk distorting payment choice, inclusion, and bank funding. Open questions include how to integrate instant payments and how behavioral substitution will evolve once a digital euro exists. [JPSS]

19th ERPB Technical Session on the Digital Euro (ECB)

The European Central Bank (ECB) posted the presentations discussed at the 19th Euro Retail Payments Board (ERPB) technical session on the digital euro held virtually on April 9. Main topics included a refresher on the fundamentals of the offline digital euro solution and its main components, and an overview of the 12-month pilot slated to start in H2 2027 to be conducted with a limited number of payment service providers, merchants and Eurosystem staff.

Canada’s Stablecoin Framework (Government of Canada)

The Government of Canada published a federal framework in which non‑bank issuers of fiat‑backed stablecoins must register with the Bank of Canada, maintain fully backed high‑quality liquid reserves, and offer at‑par redemption in the reference currency. The framework centralizes prudential oversight at the Bank of Canada while leaving trading, payments, and anti‑money‑laundering oversight to existing securities and payments regimes, aiming to enable innovation and competition in digital payments while tightening consumer protection and financial stability safeguards. It is explicitly designed to align with European Union and United States approaches and with Financial Stability Board recommendations, positioning Canadian‑issued coins for prospective cross‑border interoperability. Key open questions concern how detailed reserve, redemption, and governance standards will be calibrated in regulation over 2026–27 and how authorities will exercise expansive national‑security and public‑interest powers to deny or revoke market access. [Government of Canada]

Changes Made for KfW’s Third Blockchain Bond (KfW)

KfW announces that its third blockchain-based crypto security will migrate both registrar and distributed ledger infrastructure mid‑term to stress‑test Germany’s Electronic Securities Act framework under real market conditions. The bond will shift registrar functions from Cashlink to DekaBank and move from the Polygon blockchain to SWIAT/Regulated Layer One, while also switching wholesale payment processing from the Deutsche Bundesbank’s trigger solution at issuance to the Eurosystem’s forthcoming Pontes platform for coupons and redemption. This staged migration aims to generate evidence for scalable, standardized digital capital-market infrastructure in Europe, but leaves open whether secondary-market liquidity and operational risks will prove manageable at scale.

Making Stablecoins Stable (IMF)

The IMF published a paper that develops a theoretical framework to analyze the tension between stablecoin stability and issuer incentives. The central finding is that unregulated stablecoin issuers hold excessive risky assets to maximize profits, thereby elevating run risk while failing to internalize the welfare consequences for households. A regulator acting in the broad public interest can improve upon this outcome by mandating high-quality liquid asset backing, ideally central bank reserves, but strict liquidity requirements alone reduce issuer profitability and suppress stablecoin supply below socially optimal levels. The authors argue that achieving both stability and adequate issuance requires two complementary policy instruments: a safe backing asset requirement and a supplementary revenue source for issuers, such as remuneration on reserves or regulated data monetization. The paper draws supporting parallels from China’s e-money experience and situates its findings relative to emerging regulatory frameworks including the U.S. GENIUS Act and the EU’s MiCA regulation. [IMF]

Stablecoin Issuance Market: Four Business Models Reshaping the Market (Tiger Research)

Tiger Research published a report arguing that late‑entry stablecoin issuers can survive only by abandoning the dominant reserve‑interest model and specializing in distinct market niches. The authors show that Tether uses scale to monetize reserves while gradually repairing transparency and building a diversified real‑world asset (RWA) and investment portfolio, turning regulatory normalization into a way to defend its monetary base. StraitsX instead treats stablecoins as payments infrastructure, monetizing fee‑based transaction velocity under a Monetary Authority of Singapore license that converts compliance into a regional moat. M0 repositions issuance as shared infrastructure, using network effects across issuers and builders to become a neutral standard rather than a competing coin. KRWQ treats regulatory gaps and offshore non‑deliverable forward demand as an entry point, using offshore liquidity as an option on future domestic legitimacy, leaving open whether such sequencing can withstand eventual onshore regulatory choices. [Tiger Research]

What Are Stablecoins Used for Today? Estimating the Distribution of Stablecoins (Kansas City Fed)

The Federal Reserve Bank of Kansas City (Kansas City Fed) published an article in which Franklin Noll estimates that stablecoins are used predominantly for crypto‑finance trading, with payments accounting for less than 1 percent of supply. He finds roughly half of outstanding stablecoins sit in exchanges, decentralized finance, and related infrastructure, with another large share used for high‑value transfers and a material portion idle in rarely used wallets. This usage pattern implies that stablecoins currently function more as market plumbing and speculative liquidity than as a broad retail or commercial payments instrument, and that reliance on bridges and exchanges highlights interoperability and concentration risks in the ecosystem. [Kansas City Fed]

Self-Custodial Wallets in a Regulated World (Walletconnect and Ubyx)

WalletConnect and Ubyx published a paper arguing that self-custodial wallets can operate within existing anti–money laundering, sanctions, and tax frameworks if regulators adopt technology-neutral, outcomes-based rules and focus obligations on intermediaries at the “edge.” The authors document concrete mechanisms—such as FATF “travel rule” data capture within wallet flows, cryptographic “sign-In with X” ownership proofs, programmable token-level controls, and blockchain analytics—that allow virtual asset service providers to meet customer due diligence, travel rule, and reporting obligations without banning or custodianizing self-custody. This matters because exclusionary rules would push activity offshore, create a two-tier system, and undermine both financial inclusion and supervisory visibility, whereas regulated interoperability preserves open finance benefits while strengthening compliance. The paper highlights unresolved questions around the precise regulatory status of new wallet architectures (trusted execution environments, multi-party computation, bank-deployed wallets) and the scope and consistency of edge-enforcement obligations across jurisdictions. [Walletconnect and Ubyx]

The Central Bank of Bolivia (BCB) to Explore Wholesale CBDC in 2026 (BCB)

[November 6, 2025] Banco Central de Bolivia (BCB) issued a press release outlining a phased roadmap to explore a wholesale central bank digital currency (CBDC) dubbed the Boliviano Digital through 2026. The plan sequences stakeholder consultations, surveys of potential participants, further technical and regulatory evaluation, and prototype testing in controlled environments to minimize operational and technological risk while building institutional capacity. For policy and market structure, the initiative positions CBDC as an infrastructure upgrade for interbank payments, cost reduction, and innovation. [BCB]

Worldpay 2026 Global Payments Report (Worldpay)

Worldpay published the 2026 edition of its Global Payments Report in which it argues that global consumer payments are rapidly shifting toward digital wallets and app‑based rails, with cards adapting and crypto evolving rather than disrupting. The report documents rising wallet dominance in e‑commerce and at point of sale, regional variation in account‑to‑account systems, and the continued but declining direct share of cards as usage migrates into wallets. These developments sharpen questions about governance of national fast‑payment infrastructures, merchant routing and fee regulation, cross‑border interoperability, and the competitive position of bank‑issued cards versus platform wallets and “superapps.” They also highlight how buy-now-pay-later and card‑backed installments blur prudential and consumer‑protection boundaries, and how stablecoin‑based payment rails may need bespoke oversight alongside traditional systems. [Worldpay]

An Efficient Frontier Analysis of Stablecoin Reserve Management (VISA)

VISA published an article in which Ezechiel Copic uses an efficient frontier framework to show how new U.S. and EU stablecoin rules compress reserve returns and reorient issuer economics toward liquidity and resilience. The article models pre‑regulation reserve strategies using Tether’s historical mix to illustrate a wide opportunity set, then re‑estimates frontiers under the U.S. GENIUS Act and the EU’s Markets in Crypto‑Assets Regulation. Under GENIUS, a narrow set of high‑quality liquid assets leaves only a thin band of feasible risk‑return combinations, making reserve management resemble liquidity engineering rather than portfolio optimization. Under MiCA, lower euro‑area rates and binding bank‑deposit floors further depress and compress the frontier, especially for “significant” issuers. The analysis implies competition will shift from balance‑sheet yield to technology, distribution, and compliance, while leaving open how far reduced issuer economics may constrain market entry and long‑run innovation. [VISA]

Tokenized Finance (IMF)

The IMF’s Tobias Adrian argues that tokenization is a structural reconfiguration of financial architecture that shifts trust and risk management from institutions to programmable infrastructures. Tokenization enables atomic, real-time settlement and embedded compliance across money, banking, capital markets, and financial market infrastructures, compressing value chains but also accelerating liquidity dynamics and potential stress transmission. For emerging and developing economies, although tokenization may lower payment and market-access frictions, it heightens risks of volatile capital flows, currency substitution, and fragmented liquidity. The note emphasizes that the long-term success of tokenization depends on anchoring digital finance in public trust through clear policy frameworks and safe settlement assets, robust governance of code, legal certainty, and international coordination. Absent such anchors, tokenization risks amplifying financial instability through speed, concentration, and fragmentation, as contract-based risk management alter the nature of settlement, liquidity, and systemic risk. [IMF]

Results of the SNB 2025 Payment Methods Survey of Private Individuals (SNB)

The Swiss National Bank (SNB) reported its 2025 survey results on payment behavior among private individuals in Switzerland. The SNB finds that use of payment methods at physical points of sale is largely unchanged from 2024, with debit cards leading, followed by cash and mobile payment apps, based on diary and questionnaire responses from roughly 2,000 residents. For policy and cash-infrastructure design, satisfaction with cash access has dropped from 88% to 81%, likely reflecting the continued reduction of automated teller machines and similar access points, which may pressure authorities to reconsider minimum cash-access standards or incentives for basic cash services. At the same time, only 2% of respondents support abolishing cash, underscoring that cash still fulfills a demanded role in retail payments and resilience planning. [SNB]

Do We Really Need the Digital Euro: A Solution to What Problem Exactly? (IEA)

[April 30, 2025] The Instituto Espanol de Analysts (IEA) published a book that included a chapter by European Parliament rapporteur Fernando Navarette, that argues that a digital euro is a mis-specified response to Europe’s payments challenges and should be downgraded to a contingency “Plan B.” He contends that the core problems—trust in money post‑crisis, overreliance on non‑EU payment schemes, and stablecoin‑driven currency substitution—are better addressed through institutional and regulatory reforms, wholesale central bank digital currency (CBDC), and pan‑European instant‑payment solutions based on commercial bank money. Navarrete stresses that retail CBDC is inherently destabilizing for bank funding, raises unresolved privacy and governance risks, and risks crowding out private innovation, especially if coupled with legal tender and complex “waterfall” mechanics. He instead proposes a three‑pillar architecture: private‑led interoperable instant payments, a narrowly scoped offline digital euro, and wholesale CBDC—leaving a full retail CBDC only as a last‑resort backup if private efforts fail. [IEA]

The eNaira Journey So Far (in 2023) (CBN)

[In 2023] the Central Bank of Nigeria (CBN) published a book on the economics of digital currencies in which there was a review of how the eNaira central bank digital currency (CBDC) was designed, launched, and managed. It argues that weak demand reflects structural and institutional frictions rather than purely technological failure. The review documents a phased rollout focused on financial inclusion, payment efficiency, and monetary control, but shows that limited interoperability, burdensome onboarding, and unclear value propositions constrained uptake. It emphasizes how institutional choices around wallet tiers, distribution architecture, and bank–fintech roles reshaped market incentives, often reinforcing banks’ dominance rather than fostering broader innovation. It highlights the need to recalibrate design toward open interfaces, clearer legal and regulatory frameworks, and better alignment between central bank objectives and private‑sector business models.

Bank of Korea Launches Full-Scale Implementation of “Project Han River” Phase 2 (BOK)

The Bank of Korea (BOK) announced Phase II of Project Hangang. It aims to trial large-scale, won-pegged deposit tokens built on a wholesale central bank digital currency (CBDC) layer, to cut transaction costs for both major corporations and small merchants burdened by credit card fees, building on Phase I’s system build out and 2025 live pilot. Participating banks will expand from 7 to 9 and merchant coverage will be significantly broadened. Phase II will test person to person transfers, biometric authentication, and automatic deposit token funding and sweep out. It will also deepen programmability, using digital vouchers in blockchain based treasury pilots such as an electric vehicle (EV) charging infrastructure project, and continue experiments with AI agent payments and tokenized bonds and equities. The 2026 agenda includes support for government treasury execution, and external consulting on regulation and operating models, with a Phase III vision of low cost universal payments, programmable financial services, and infrastructure for Korea’s broader digital asset ecosystem.

ECB Calls for Experts to Participate in Digital Euro Rulebook Development (ECB)

The European Central Bank (ECB) launched a call for experts to join two workstreams under the digital euro Rulebook Development Group (RDG) to support further development of the digital euro scheme rulebook, which will set common rules, standards and procedures for using the digital euro across the euro area. One workstream (G5) will focus on implementation specifications for ATMs and payment terminals, including communication technologies, integration of offline digital euro functionality and leveraging existing standards, requiring expertise in ATM and terminal interfacing or provision. The other (B1) will design a certification and approval framework for testing and certifying payment and acceptance solutions and infrastructure used by payment service providers in the digital euro ecosystem, requiring expertise in payments and acceptance devices. The ECB notes that the flexible draft rulebook will be updated to reflect the outcome of the EU legislative process, with any decision to issue a digital euro to follow only after legislation is adopted.

ECB Workshop on Pontes Platform Decentralized Programmability (ECB)

The ECB published an updates to its Pontes project aimed at enabling the settlement of distributed ledger technology (DLT) transactions using central bank money (CeBM). Pontes is the near-term DLT-based interoperability solution linking DLT platforms with TARGET Services so DLT transactions settle in CeBM, using API-based trigger and hash-link mechanisms and dedicated DLT cash wallets funded from TARGET accounts. The update focused on a workshop on market-developed smart contracts deployed by national central banks on the Eurosystem DLT (“decentralized programmability”) that would enable cash-locking for delivery-versus-payment, programmable payments, microtransactions, DLT interoperability, and automated corporate actions. [ECB]

Consultation on the Eurosystem’s Appia Project (ECB)

The ECB also published an update to its Appia project aimed at enabling the settlement of DLT transactions using CeBM. Appia is the longer-term initiative to provide tokenized CeBM for DLT-based wholesale markets via a unified settlement ecosystem. The update concerns the launching a formal consultation inviting market and public authorities to comment on Appia’s proposed DLT‑based wholesale ecosystem design and six‑block workplan via a structured questionnaire due 22 April 2026. Feedback will shape standards, governance choices, cross‑border linkages, and prioritization of analytical and practical work toward a 2028 blueprint. [ECB]

SEC Approves Nasdaq’s Securities Tokenization Plan (SEC)

The U.S. Securities and Exchange Commission (SEC) approved a Nasdaq rule change allowing certain listed securities to clear and settle in tokenized form via a Depository Trust Company (DTC) tokenization pilot. The order authorizes trading tokenized versions of large-cap equities and major index exchange-traded funds (ETFs) on the same order book, with identical CUSIP, symbol, rights, and execution priority as traditional shares, with tokenization preferences expressed through an order flag and implemented post‑trade by DTC. This embeds distributed-ledger-based entitlements within existing exchange, clearing, and surveillance infrastructures, preserves T+1 settlement, and treats tokenized and traditional shares identically for fees, market data, and audit trail. The SEC frames the decision as technology‑neutral, while leaving broader questions about alternative tokenization models, issuer choice, and future non‑fungible tokenized instruments to subsequent rulemakings.

Zero-Knowledge Proof Authentication for Offline CBDC Payments (arXiv)

Santanu Mondal and T. Chithralekha propose a hybrid offline central bank digital currency (CBDC) architecture that uses zero-knowledge proofs (ZKPs) and secure hardware to enable cash-like payments on resource-constrained internet of things (IoT) devices while preserving regulatory oversight. The system combines a two-tier CBDC model with hierarchical “main wallet / IoT sub‑wallets,” secure elements and trusted execution environments for tamper-resistant key storage and counters, and NFC/BLE device-to-device transfers backed by lightweight ZKPs. This operationalizes intermittently offline CBDC designs, translating privacy-preserving anti–money laundering and counter–terrorist financing rules into on-device limits and ZKP circuits rather than continuous online monitoring, thereby shifting supervisory leverage into protocol and hardware design choices. Unresolved are empirical tradeoffs among proof complexity, device diversity, and real-world performance under regulatory stress scenarios. [arXiv]

Which is the Fairest of all Tokenized Monies? (OMFIF)

OMFIF published an article in which Ousmène Mandeng pitches tokenized money market fund (MMF) shares as an alternative tokenized settlement asset. They offer bankruptcy‑remote, interest‑bearing claims on sovereign or high‑quality assets rather than bank balance sheets. By enabling instant delivery‑versus‑delivery transfer and collateralization without title transfer, tokenized MMFs could shift institutional liquidity management from episodic subscription/redemption to continuous circulation, potentially easing run dynamics and unlocking high‑quality collateral for intraday liquidity and cross‑border settlement. Constant net asset value MMFs invested in government securities could function as par settlement instruments with favorable prudential treatment, positioning them as strong competitors to tokenized deposits and stablecoins in wholesale use cases. Key uncertainties concern the robustness of distributed ledger technology, the status of the on‑chain versus off‑chain legal register and the prudential and regulatory classification of these instruments, which will determine their scalability and systemic role. [OMFIF]

How Canada Can Shape the Future of Stablecoins and Digital Payments [CD Howe Institute)

The CD Howe Institute published an article in which Peter MacKenzie and Mark Zelmer argue that Canada must rapidly operationalize its Stablecoin Act and consider a central bank digital currency (CBDC) to avoid ceding payment-system sovereignty to U.S. dollar-linked stablecoins enabled by the GENIUS Act. They note that GENIUS-backed U.S. stablecoins and foreign exchanges could become core Canadian payment rails, undermining monetary sovereignty, domestic oversight, and data access, while Canada’s high-level Stablecoin Act leaves key issues on reserves, operations, and foreign platforms unresolved. The authors propose a function-based, two-track regime that treats pure payment stablecoins as fully backed payment instruments under Bank of Canada oversight and keeps tokenized deposits in the banking framework, complemented by Bank of Canada liquidity lines and a CBDC settlement layer to preserve singleness of money and cross-platform interoperability. They stress that the open question is whether Canada will implement detailed, “comparable” rules fast enough to shape international arrangements rather than import foreign standards.

Federal Court Ends Custodia Bank’s Legal Bid for a Master Account (CoinTelegraph)

The US Court of Appeals for the Tenth Circuit has rejected Custodia Bank’s last attempt to force the Federal Reserve to grant it a master account, effectively ending the Wyoming crypto-focused bank’s five‑year effort to gain direct access to Fed payment rails and reserve accounts. Custodia had argued that the Monetary Control Act entitled it, as a state‑chartered institution, to such access, but multiple courts have now affirmed that the Fed retains discretion over master account approvals. The Tenth Circuit, in a 7–3 decision, declined to rehear Custodia’s appeal, though a dissenting judge warned that a master account is “indispensable” to a bank’s operations and that denial is “akin to a death sentence.” The ruling comes shortly after Kraken secured a limited master account from the Federal Reserve Bank of Kansas City, raising broader questions about how and on what terms crypto firms can obtain direct connections to systems like Fedwire.

Public vs. Private Payment Platforms: Market Impacts and Optimal Policy (Bank of Canada)

The Bank of Canada published a paper that studies competition between a welfare-maximizing public payment platform (e.g., fast payment system) and a profit-maximizing private platform. It finds that the public system should not simply aim to be as cheap as possible, because if it undercuts the private one too aggressively it can actually reduce the overall benefits from having both systems in the market. When a public system enters, more people and businesses use electronic payments and consumers are generally better off, but private providers tend to respond by putting more of their fees onto merchants. The authors also argue that if the public platform is required to cover its costs but forbids fees on consumers, it must load more of those costs onto merchants via fees, which could then reduce merchant participation, which in turn weakens the value of the platform to consumers and erodes the potential welfare gains from having the public system in the first place. [Bank of Canada]

Emerging Capabilities in Fast Payments: NFC and Offline Payments (World Bank)

The World Bank published a technical note outlining how fast payment systems (FPS) can incorporate near-field communication (NFC) and offline payment capabilities as “extended” channels and instruments, largely implemented at the payment service provider (PSP) level rather than in central infrastructure. The paper argues that NFC can shift consumer-initiated payments from cards and QR codes toward FPS by providing tap-based, tokenized, real-time credit transfers across payer‑ and payee‑initiated models, while raising device, scheme-rule, and fraud‑management questions. Offline models—deferred, temporary person‑to‑person, and person‑to‑merchant wallets—are positioned as critical for transit, low‑connectivity regions, and inclusion, but they introduce double‑spend, liability, and supervision challenges that require tight limits, secure elements, and explicit policy stances on where offline FPS should remain an exception versus a mainstream channel.

Call for Payment Service Providers to Participate in Digital Euro Pilot (ECB)

The European Central Bank (ECB) has opened applications for euro area licensed payment service providers (PSPs) to join a twelve‑month digital euro pilot in the second half of 2027. It will use a non‑legal‑tender “beta” digital euro in a controlled environment to test technical, operational and user experience (UX) aspects of P2P (online/offline) and P2B payments at physical and online points of sale. PSPs will onboard users and merchants without remuneration, be selected based on eligibility plus weighted criteria (compliance status, technical capacity, market presence, geographic/segment coverage, delivery track record), and then work directly with national central banks and Eurosystem teams. The ECB has published technical and procedural documentation and PSPs must apply by May 14, 2026, with the whole exercise framed as preparatory and conditional on future EU legislation and a separate decision to issue a digital euro. [ECB]

Towards a Consistent Regulatory Approach to Illicit Payments (BIS)

The Bank for International Settlements (BIS) published a paper that develops a framework for how illicit payment rules, centered on whether payment instruments rely on intermediaries, shape both illicit and legitimate users’ choice among payment instruments. Because detection probabilities differ by design and by whether instruments fall inside or outside anti-money laundering (AML) scope, actors shift activity toward instruments with the lowest expected detection and sanctioning, undermining overall effectiveness and prompting iterative regulatory expansion. Illicit payment measures also constrain informational privacy and freedom of choice for legitimate users, creating a privacy–integrity trade off moderated by data protection regimes and trust in public authorities. The paper argues for a forward looking architecture that applies uniform, risk based lex generalis AML/CFT and data protection requirements across all intermediated instruments, while using lex specialis tools such as transaction/holding limits, reliance on touch points, and additional duties on issuers or platforms for instruments without intermediaries, to reduce regulatory driven substitution across payment instruments while preserving both integrity and user privacy. [BIS]

Targeted Report on Stablecoin and Unhosted Wallet P2P Transactions (FATF)

The Financial Action Task Force (FATF) published a report that concludes that stablecoins, now a major share of on‑chain and illicit virtual‑asset activity, create elevated money laundering/ terrorist financing/ proliferation financing (ML/TF/PF) risks, especially via P2P transfers through unhosted wallets outside direct anti-money laundering/ countering the financing of terrorism/ counter proliferation financing (AML/CFT) controls. FATF affirms that stablecoins are virtual assets and that issuers, intermediaries and relevant DeFi actors must be regulated as virtual asset service providers (VASPs) or financial institutions under Recommendation 15, with licensing, supervision, Travel Rule compliance and sanctions screening. Jurisdictions are encouraged to build stablecoin‑specific regimes, require issuers to embed technical controls (freeze, burn, allow/deny‑lists) and strengthen cross‑border supervisory cooperation and data collection on P2P use. The report stresses expanded use of blockchain analytics, targeted controls on transfers to unhosted wallets, structured public‑private partnerships, and detailed red‑flag indicators to guide monitoring and investigations.

New Recommendations for Public Payment Preparedness (Riksbank)

Sveriges Riksbank issued new recommendations on “public payment preparedness,” urging households to see themselves as part of Sweden’s total defence and to maintain multiple means of payment so essential purchases can continue during disruptions, crises or war in an increasingly digitalized environment. It advises adults to hold at least SEK 1,000 in cash at home (in mixed denominations) for roughly a week’s essential spending and to use cash periodically so cash infrastructure remains robust, to have at least two payment cards linked to different card networks (e.g. Visa and Mastercard), to ensure access to a mobile payment service such as Swish that relies on different infrastructure than cards, and to keep physical payment cards and PINs accessible even if mobile wallets are normally used. The recommendations feed into the Riksbank’s broader work on national payment contingency and will also feature in the Payments Report 2026, due on March 12, 2026. [Riksbank]
