BRICS Countries Discussing Linking CBDCs and Fast Payment Systems (Nagaland Post)

Reserve Bank of India (RBI) Governor Sanjay Malhotra reportedly said that BRICS nations are discussing linking central bank digital currencies (CBDCs) and fast payment systems (FPSs) to facilitate cheaper and faster cross-border funds transfers. The BRICS countries are Brazil, Russia, India, China, South Africa, Egypt, Ethiopia, Iran, Saudi Arabia, Indonesia, and the United Arab Emirates (UAE). Governor Malhotra also reportedly said that efforts are on to internationalize the rupee, including by expanding the number of memorandums of understanding (MoUs) between central banks that it signs for promoting bilateral trade in local currencies. At present, India and the RBI have signed such agreements with Indonesia, Maldives, Mauritius and the UAE. [Nagaland Post]

India to Launch CBDC-Based Direct Benefit Transfer POC in Chandigarh and Dadra & Nagar Haveli (GOI)

The Government of India (GOI) will launch programmable central bank digital currency (CBDC) based direct benefit transfers (DBTs) under the Pradhan Mantri Garib Kalyan Anna Yojana (PMGKAY) food subsidy program in the Territories of Chandigarh and Dadra & Nagar Haveli on August 14. With the launch of this scheme the subsidies will be transferred to eligible PMGKAY beneficiaries in the form of programmable digital rupee tokens directly into their CBDC wallets, instead of via traditional bank account transfers. This subsidy can be used to purchase food grains from listed merchants through a secure , trackable, and real-time digital payment system. The aim is to ensure transparent and thorough distribution of public funds , while also reducing leakages , embezzlement, and cash transactions associated with traditional subsidy distribution mechanisms. It will facilitate quick and secure transfer of benefits to beneficiaries and promote financial inclusion through simple wallet-based transactions. This initiative builds on pilots carried out earlier in 2026 in Puducherry and Gujarat, and is envisioned as a proof-of-concept for the nation and a scalable template for adoption by other states and territories.

Tokenized Deposits: Old Wine in New Bottles? (SUERF)

SUERF published a policy note by Alistair Milne that argues tokenized deposits offer little operational novelty over conventional account-based deposits, since the automation, programmability, and 24/7 processing attributed to distributed ledger technology are equally achievable on centralized ledgers. Decentralization’s only distinct capability is pseudonymous transfer without intermediaries—which banks are not pursuing. Tokenized deposits’ genuine appeal is confined to “on-us” transactions on a single bank’s balance sheet, avoiding interbank settlement complexity. JP Morgan’s Kinexys, adopted for corporate multi-currency cash management, exemplifies this, but reflects business logic rather than ledger technology. Milne characterizes bank tokenization efforts as a defensive marketing response to the stablecoin threat. Open questions include whether interoperability initiatives such as UK Finance’s tokenized sterling deposits project can generate domestic adoption incentives, and whether capital markets tokenization—requiring 100% reserving and settlement-asset recognition—warrants separate assessment.

Latest Pix Management Report Presents Agenda for its Future Evolution (BCB)

Banco Central do Brasil (BCB) published an update on the main advances of the Pix ecosystem between 2023 and 2025, the results achieved by the instant payment system (IPS) and the prospects for its evolution in the coming years. Looking ahead, the BCB is discussing bilateral connections and participation in multilateral instant payment hubs. Existing models let Brazilians pay abroad and non-residents pay in Brazil through partnerships with foreign institutions and Pix QR codes, but Pix itself settles only the domestic real leg, with the corresponding foreign-currency transfer occurring later through conventional remittance rails. Connecting Pix to foreign IPSs via bilateral links and multilateral hubs could enable remittances and merchant payments with local-currency availability within seconds, while reducing fees, improving speed, access, and transparency.

China Cuts Durian Settlement to 30 Minutes with First Outbound e-CNY Payment to Malaysia (SCMP)

China has completed its first outbound payment via the Cross‑Border e‑CNY Express Service (CBETS) to Malaysia, settling a 43,000 yuan shipment of fresh durian. The transaction was executed by China Construction Bank’s Xiamen branch in coordination with its Labuan branch in Malaysia, using direct bank‑to‑bank ledger transfers and on‑the‑fly conversion into Malaysian ringgit. Compared with traditional correspondent banking networks operating under the Society for Worldwide Interbank Financial Telecommunication (SWIFT) system, this cut settlement to 30 minutes from one to three days and eliminated clearing fees of up to 6% and per‑transaction charges of $25 to $35. CBETS, operated by the e‑CNY International Operation Center under the guidance of the People’s Bank of China’s Digital Currency Institute, provides on‑chain and off‑chain connectivity and 24/7 cross‑border settlement. [SCMP]

FYI most publications are presenting this as a central bank digital currency (CBDC) story, but there’s no concrete evidence that it is. For starters, the Peoples Bank of China (PBOC) announced earlier in the year that the e-CNY is now a tokenized commercial bank deposit-based platform. And earlier stories going back to September 2025 (see below) that I missed make it clear that the Cross‑Border e‑CNY Express Service (CBETS) platform is only operating under PBOC guidance, so none of these platforms are CBDC-based according to the core part of the CBDC definition; a direct liability of the central bank.

26 Financial Institutions Sign On as direct participants with e-CNY Center International (SCIO)

[June 17, 2026] The State Council Information Office of China (SCIO) announced that the e‑CNY International Operation Center, which operates under the guidance of the Digital Currency Institute of the People’s Bank of China, has enrolled 26 institutions as direct participants on its Cross-Border e-CNY Transfer Services (CBETS) platform. Since the beginning of 2026, the e-CNY International Operations Center, which commenced operations in September 2025, has upgraded its three major platforms into the CBETS. CBETS provides on-chain and off-chain connectivity and 24/7 settlement, reducing reliance on three-to-five intermediary correspondent banks per transaction. The 26 aforementioned institutions include Standard Chartered China and Chinese bank branches in Thailand, Singapore, Laos, and Qatar. [SCIO]

e-CNY International Operation Center Officially Launched in Shanghai (PBOC)

[September 25, 2025] The People’s Bank of China (PBOC) formally launched the e‑CNY International Operation Center in Shanghai to provide dedicated infrastructure for cross‑border use of the digital renminbi, framed as part of a broader upgrade of monetary and payment systems. The center’s three core “business platforms” are a cross‑border digital payment platform, a blockchain service platform, and a digital asset platform, together supporting e‑CNY cross‑border settlement, asset tokenization, and related digital financial services. Institutionally, the PBOC’s Digital Currency Institute will build and operate these systems, with a mandate to connect domestic and foreign financial infrastructures and support international operation of e‑CNY.

Project Agorá Real Value Testing (BIS)

The Bank for International Settlements (BIS) and Institute of International Finance (IIF) completed real value testing of their Project Agorá multi‑currency programmable platform for atomically settled wholesale cross‑border payments using wholesale central bank digital currency (CBDC) and tokenized commercial bank deposits. The trials involved 28 private-sector financial institutions and central banks executing approximately CHF 800,000 in transactions across 17 scenarios (corporate, interbank, intra-group, and payment‑versus‑payment) and six major currencies (CHF, EUR, GBP, JPY, KRW, USD) across Asia, Europe and North America, with end‑to‑end processing averaging 80 seconds from submission to settlement. The exercise focused on feasibility and operational performance under realistic conditions, highlighting improvements in speed, transparency, and status/routing visibility relative to existing correspondent banking architectures. However, still to be resolved are questions around legal treatment of tokenized claims, settlement finality, data‑sharing, and governance models. [BIS]

Are Stablecoins Efficient for Remittances? Evidence from a Mystery Shopping Exercise (Banca d’Italia)

Banca d’Italia published a paper that finds stablecoin-based remittances offer no systematic cost advantage over traditional channels, based on a mystery shopping exercise. Researchers transacting as ordinary customers transferred 200 USD Coin (USDC) across ten corridors linking Italy with Argentina, Brazil, South Africa, the UAE, and Japan. Total costs ranged from 0.30% to nearly 9%, with the on-chain transfer contributing a marginal 0.4%; the on- and off-ramp fiat-conversion steps, exchange fees, and funding method drove costs and duration. Speed depended on domestic payment infrastructure: instant-payment jurisdictions (Brazil’s PIX, Italy’s TIPS) settled end-to-end under 20 minutes, while standard bank transfers extended settlement to one or two days. Regulatory design shaped operator availability and feasibility. However, cross-corridor comparability is confounded by Argentina’s parallel exchange rates and single-stablecoin, and single-transaction scope limits generalization. [Banca d’Italia]

Bolivian Government Considers including USDT as an Official Form of Payment (La Razon)

La Razon is reporting that Bolivia’s government is considering recognizing USDT as an additional settlement currency within the domestic payment system alongside the dollar and boliviano, following a 2024 Central Bank of Bolivia resolution that lifted a prior ban on crypto operations amid foreign‑exchange pressures. Authorities highlight that current usage of crypto-assets remains outside legal‑tender status and operates in a regulatory vacuum beyond the initial unblock, creating both market disruption and compliance gaps. The policy discussion is shaped by Bolivia’s placement on the Financial Action Task Force (FATF) “grey list,” with explicit concern that any formal integration of USDT must address anti‑money‑laundering and counter‑terrorist‑financing (AML/CFT) vulnerabilities in crypto flows. The key unresolved issue is the design of a robust regulatory framework governing crypto‑asset use in payments. [La Razon]

Stablecoins and the Future of the Dollar (Philadelphia Fed)

An article by the Philadelphia Fed’s Joseph Abadi argues that reserve‑backed stablecoins, reinforced by the GENIUS Act, will entrench the dollar and position stablecoins primarily as regulated payment instruments rather than interest‑bearing stores of value. It traces the shift from early trading‑oriented and algorithmic designs, through the Terra collapse and the Silicon Valley Bank–linked run on USD Coin, to the current dominance of transparently backed, short‑term dollar‑asset portfolios that depend on public safety nets in stress. This matters because U.S. law now treats stablecoins as fully reserved “digital cash,” channels them into settlement and remittance use, and is intended to prevent disintermediation of bank deposits, even as yield‑like products via exchanges expose a regulatory gap. The unresolved issue is whether Congress closes this “yield loophole” and how cross‑border demand interacts with capital controls. [Philadelphia Fed]

Zelle Heads to India, Unveils ZelleUSDSM Stablecoin For Other Markets (Zelle)

Early Warning, the operator of U.S. fast payment system (FPS) Zelle, will launch Zelle in India first for U.S. consumers sending money to family and friends abroad, with initial availability expected before year-end, and it also introduced ZelleUSD (ZLUSD), a U.S. dollar-backed stablecoin intended to support future international payments in other markets. The company framed the move as an expansion of its domestic payments network into cross-border remittances, saying financial institutions could offer near-instant transfers through existing banks and credit unions. [Zelle]

The Anatomy of Stablecoin Transactions (BIS)

The BIS published a paper by Schär, Kosse, Rice, Shirakami, and Siridhasanakul that analyze 593 million Ethereum event logs across 141 million transactions to argue that stablecoin transfers are routinely embedded within atomically executed bundles combining trading, lending, and settlement, distorting standard interpretations of stablecoin activity. While 31.6% of transactions involve such complexity, these generate nearly 60% of all transfer events, meaning transfer-level data misclassifies most observations as standalone payments. USDT, USDC, and PYUSD differ systematically in co-usage, computational burden, urgency, and business-hour alignment, reflecting distinct institutional designs rather than interchangeability. The action-set classification offers supervisors a basis for activity-based oversight, while divergent jurisdictional timing patterns underscore the need for cross-border data-sharing among regulators. [BIS]

Stakeholder Engagement and Roadmap for Philippines Wholesale CBDC (IMF)

The IMF published a technical assistance report on stakeholder engagement and roadmap development for Bangko Sentral ng Pilipinas’s (BSP’s) Project Agila wholesale central bank digital currency (wCBDC) project. As part of this work, tokenized government bond settlement and cross-border payments were identified as priority wCBDC use cases. Workshops with financial institutions, the Bureau of the Treasury, and market infrastructure providers highlighted real-time gross settlement (RTGS) system settlement-window limitations, capital market shallowness, and correspondent-banking-dependent cross-border payment inefficiencies. The roadmap calls for cost-benefit analysis of wCBDC against alternatives including trigger solutions and omnibus accounts, although the Securities Clearing Corporation (SCCP) prefers its existing fee-free settlement-bank arrangements, which also provide netting and liquidity-saving features not easily replicated on RTGS, over direct settlement access. Legal framework gaps and financial integrity regulation compliance remain key open issues. [IMF]

MoneyGram Launches MGUSD Stablecoin (MoneyGram)

MoneyGram announced the launch of its MGUSD U.S. dollar stablecoin to underpin its global remittance and payments network. MGUSD is framed as an infrastructure layer integrated into a self-custodial wallet in the MoneyGram app, initially in the United States, using Bridge as regulated issuer, M0 smart contracts and Stellar for settlement, with Fireblocks providing custody. Unresolved are regulatory treatment across markets, interoperability with other stablecoins and systems, and how issuance and reserves will be supervised at scale. [MoneyGram]

Advancing Digital Payments in Bhutan (ADB)

The Asian Development Bank (ADB) published an assessment of Bhutan’s digital payment infrastructure that included an update on Bhutan’s Royal Monetary Authority (RMA) central bank digital currency (CBDC) projects, both retail and wholesale. The aim is to provide more accessible and secure financial services to a broader population, including underserved communities, and streamline cross‑border transactions, including by reducing the need for correspondent banking relationships and simplifying currency conversion processes in international trade. However, the ADB found that there are gaps in existing financial services regulations and payment systems rules will need to be addressed first. [ADB]

Call for Expressions of Interest to Participate in the Appia Contact Group (ECB)

The European Central Bank (ECB) is inviting financial market stakeholders and public sector bodies to express their interest in participating in the Appia Contact Group Appia CG). The Appia project is aimed at enabling the settlement of distributed ledger technology (DLT) transactions using tokenized central bank money (CeBM) via a unified settlement ecosystem. It runs alongside the Pontes project, aimed at settling DLT transactions using API-based trigger and hash-link mechanisms and dedicated DLT cash wallets funded from TARGET accounts, which has its own contact group. The Appia CG will contribute to the Appia roadmap and advise on the operation and evolution of the Pontes pilot. Membership targets future users, contributors to Appia, relevant value‑chain actors, and industry associations. National central banks and selected European authorities participate as observers; the group is chaired and serviced by the European Central Bank and meets quarterly, with work outputs generally published. [ECB]

The ECB Publishes List of Digital Euro Steering Committee Members (ECB)

Project Agorá: A Shared Programmable Platform for Wholesale Cross-Border Payments (BIS)

The Bank for International Settlements (BIS) published an update on Project Agorá, a public-private collaboration convened by the and the Institute of International Finance (IIF). It proposes a two-layer distributed ledger platform for wholesale cross-border payments, combining tokenized central bank reserves with tokenized commercial bank deposits linked via smart contracts. The architecture explicitly preserves correspondent banking and the two-tier monetary system — a design choice that limits ambition considerably, since the structural inefficiencies of correspondent chains (nostro prefunding costs, corridor de-risking, access inequality) remain largely intact. The principal claimed advantages — atomic settlement eliminating credit risk, and parallel rather than sequential compliance processing — are real but narrow, and address wholesale volumes where settlement failures are costly rather than the access and cost problems motivating the G20 reform agenda. FX settlement and liquidity-saving mechanisms are out of scope. Governance arrangements, settlement finality across jurisdictions, cybersecurity at production scale, and coordinated financial crime information-sharing are all unresolved, leaving the prototype considerably further from deployment than the report’s tone suggests.

BOE Considers Keeping Digital Pound On Ice as Rivals Race Ahead (Bloomberg)

The Bank of England (BOE) and HM Treasury (HMT) are reportedly considering slowing down the digital pound project to defer making an immediate firm decision to approve or scrap it. Officials have been encouraged by private-sector innovation—especially tokenized deposits—that could deliver many CBDC benefits (faster, cheaper payments) within the existing regulated banking system, reducing the urgency to build a central-bank solution. The project has faced skepticism from the public, Parliament, and even BOE Governor Andrew Bailey, who remains unconvinced of the need for a retail CBDC. A decision to build would entail upfront costs in the hundreds of millions of pounds (albeit later offset by CBDC income), voluntary participation by banks, and risk of political backlash over privacy concerns. [Bloomberg]

Meta Rolls Out Stablecoin Payments (Coindesk)

Meta rolled out digital currency payouts for select creators in Colombia and the Philippines. The payouts use the USDC stablecoin on either the Solana or Polygon blockchain networks, processed via Stripe’s Link wallet and accompanied by tax reporting from both Meta and Stripe. The initiative marks Meta’s return to stablecoins after it attempted to introduce the Libra token, later renamed Diem, only to shut down the project amid regulatory scrutiny in 2022. [Meta]

Central Bank Digital Currency and Monetary Architecture (Dirk Niepelt)

In a literature review that has been accepted for publication by the Journal of Economic Literature, Dirk Niepelt argues that the macroeconomic consequences of retail central bank digital currency (CBDC) depend primarily on the policy choices accompanying its introduction. Organizing the survey around a neutrality result, the paper demonstrates that bank disintermediation does not independently constitute a source of non-neutrality, provided the central bank recycles CBDC proceeds to banks on deposit-equivalent terms. Most existing research conflates policy-contingent with fundamental sources of non-neutrality, obscuring the extent of policymaker control. Because CBDC represents a structural shift in monetary architecture rather than a technical payment upgrade, it raises political economy questions that exceed the conventional mandate of central banks. [Niepelt.ch]

On the Resilience of Payment Methods (NBER)

The U.S. National Bureau of Economic Research (NBER) published a paper that argues, using multi-source U.S. and cross-country evidence, that cash functions as critical fallback liquidity when electricity outages disable digital payment infrastructure during natural disasters. Event studies across store-level transaction data, card aggregates, and household scanner records show that hurricanes generate persistent outages, shifting spending composition sharply toward cash, while pre-disaster expenditure spikes are credit-financed stockpiling. The finding that payment-system fragility is a first-order attribute of any instrument has direct implications for regulators overseeing cashless transitions, mandatory acceptance rules, and the design of offline-capable central bank digital currencies.

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]
