Compliance Design Options for Offline CBDCs: Balancing Privacy and AML/CFT (IEEE)
Compliance Design Options for Offline CBDCs: Balancing Privacy and AML/CFT (IEEE)
The Institute of Electrical and Electronics Engineers (IEEE) published a paper that examines the design options for offline central bank digital currency (CBDC) that balance user privacy with anti-money laundering and counter-terrorism financing (AML/CFT) compliance requirements. The paper presents a compliance-by-design framework for evaluating technologies that can enable CBDC transactions without network connectivity while maintaining regulatory oversight. It classifies privacy design options and corresponding technical building blocks for offline CBDCs, along with their impact on AML/CFT measures, and outlines commonalities and differences between offline and online solutions. As such, it provides a conceptual framework for further techno-legal assessments and implementations. The paper finds that offline CBDC functionality introduces additional degrees of freedom for privacy design compared to purely online systems, with the highest privacy options limiting AML/CFT compliance to basic transaction thresholds and identity verification, while lower privacy models enable sophisticated monitoring including transaction screening, sanctions checks, and graph analysis.

ECB Selects Digital Euro Service Providers (ECB)
The European Central Bank (ECB) has selected service providers for five key components of the digital euro project, following a call for applications and tender process. However, the actual development of components will only proceed pending adoption of the Digital Euro Regulation and further ECB Governing Council decisions. No payments have been made yet, and the agreements include safeguards to adapt to possible legislative changes. Framework agreements have been signed for: (i) alias lookup (Sapient and Tremend Software Consulting), (ii) risk and fraud management (Feedzai), (iii) app and software development kit (SDK) development (Almaviva and Fabrick), (iv) offline payment solutions (Giesecke+Devrient), and (v) secure exchange of payment information (Senacor). Service requests will initially be directed to the above providers, but second-ranked providers may be approached if required (see press release for full list). [Source: ECB]

Make the Digital Euro Work for Merchants to Ensure it Meets its True Potential (IRE)
Independent Retail Europe (IRE), part of the Merchant Payments Coalition Europe, urged European policymakers to ensure the digital euro is designed to benefit merchants as well as consumers. The coalition argues for a simple, uniform transaction fee capped at 4 cents, allowing merchants to incentivize adoption and keep payment costs low, and for digital euro transactions to be accessible both online and offline without added complexity. They recommend prioritizing in-store and e-commerce payments over person-to-person use, enabling merchants to hold and use digital euros for supplier payments, and building a single, standardized European payments infrastructure to foster competition and integration. The statement emphasizes that the digital euro's potential for innovation, cost reduction, and resilience depends on transparent, inclusive, and merchant-focused legislative and technical decisions.

The digital euro has enraged half of Brussels
Politico published an article about how the European Central Bank (ECB) push for a digital euro is provoking controversy across Brussels, especially among banks and right-leaning politicians. The legislative process, led by skeptical European Union (EU) lawmaker Fernando Navarrete, is mired in political debate: privacy advocates demand strong safeguards, some governments insist on offline use. Another ongoing debate is whether banks should be paid for distributing digital euros and ensuring their payment rails accept and profit from digital euro transactions. Also the lEuropean Parliament will have to work with the Council of the European Union, which represents member countries whose ministers are being lobbied by their respective banking industries. The final legislative framework likely won’t be ready before May 2026, so practical rollout is unlikely before 2028. [Source: Politico]

Wholesale Central Bank Money in the Context of Technological Innovation (BIS)
Wholesale Central Bank Money in the Context of Technological Innovation (BIS)
The Bank for International Settlements (BIS) published a report, produced by a group of seven major central banks, that examines the implications of technological innovation—especially distributed ledger technology (DLT) and tokenization—for wholesale central bank money (CBM) and settlement systems. The report finds that while wholesale CBM has existed for decades in the form of reserves, “wholesale CBM tokens” represent a new technical form enabling programmability and composability, but their fundamental economic function remains unchanged. The report lays out options and trade-offs for central banks, including whether to support private settlement solutions, enhance existing systems, or build new infrastructures—potentially with integration of multiple assets/tokens. While technological advances like DLT could improve efficiency, interoperability, and resilience, the report stresses that choices will differ by jurisdiction and caution is needed to avoid liquidity fragmentation, loss of central bank oversight, and inefficient duplication. Ultimately, central banks must balance innovation, risk management, and policy objectives when considering whether and how to make central bank money available for the settlement of tokenized wholesale transactions, with international cooperation seen as important for navigating trade-offs and possible next steps.

Revisiting National, Economic, and Monetary Sovereignty (SSRN)
Revisiting National, Economic, and Monetary Sovereignty (SSRN)
In a paper posted on SSRN, Ulrich Bindseil (ex-ECB) and Richard Senner (Swiss National Bank) examine national, economic, and monetary sovereignty, defining sovereignty as the ability of a community to make and implement collective decisions in its people's interest. They argue that sovereignty remains highly relevant despite challenges from globalization, digitalization, and international organizations, as states retain fundamental legislative and enforcement powers, particularly over legal frameworks governing money and finance. They distinguish between domestic sovereignty (freedom from internal impairments like corruption or institutional weakness) and international sovereignty (ability to manage cross-border relations and exclude external interference). The paper gives special attention to monetary sovereignty, which encompasses the state's capacity to regulate currency, conduct monetary policy, and organize payment systems. Drawing on historical analysis from Bodin through Knapp's State Theory of Money, the authors demonstrate that money is fundamentally a legal construct requiring state involvement, while acknowledging ongoing debates between those favoring stronger public roles (progressives) versus market-based solutions (libertarians). They conclude that effective monetary sovereignty—understood normatively as serving societal welfare rather than maximizing state power—requires nations to actively address challenges like payment system dominance by foreign firms, crypto-assets facilitating illicit transactions, and the balance between central bank independence and democratic accountability.

Implications of Financial Architecture Change (SNB)
Dirk Niepelt presented a paper at a Swiss National Bank (SNB) seminar that examines how shifts such as the introduction of retail central bank digital currencies (CBDCs) and private currencies can impact the economy. The paper identifies specific conditions—such as policy design, transfer mechanisms, and bank lending support—under which these changes can occur without altering real economic outcomes, a concept termed as “neutrality.” It argues that while a neutral transition to CBDCs is feasible through careful management, introducing private currencies poses greater challenges, often resulting in significant effects on resource allocation and market equilibrium. Ultimately, the economic impact of such financial innovation is not predetermined but depends on policy choices, institutional constraints, and underlying financial frictions. [Source: SNB]

Strategic Digitization in Currency and Payment Competition (JFE)
Strategic Digitization in Currency and Payment Competition (JFE)
The Journal of Financial Economics (JFE) published an article that analyzes how competition from private digital money (like cryptocurrencies and stablecoins) and foreign currencies is driving national governments to digitize their own currencies and modernize payment systems. The authors find that less-dominant currencies tend to digitize faster to gain a competitive edge, while dominant ones like the U.S. dollar delay action until truly threatened. If governments hesitate too long, private digital money can take over, reducing the role of traditional fiat currencies in global payments. The study highlights that regulation, public–private partnerships, and strategic timing all impact this competition, and achieving efficient outcomes will require cross-border cooperation. Ultimately, the enduring significance of fiat currencies in digital payments depends on strategic, timely, and coordinated digitization by governments.

Retail CBDCs In Practice: The Experience of the Sanddollar, E-CNY and JAM-DEX (SSRN)
Retail CBDCs In Practice: The Experience of the Sanddollar, E-CNY and JAM-DEX (SSRN)
A team of central bankers posted a paper on SSRN that reviews reviews the practical rollout and early experiences of retail CBDCs in The Bahamas (SandDollar), China (e‑CNY), and Jamaica (JAM‑DEX®) as of August 2025, noting that early public uptake was modest but that more recent data point to a gradual increase in use. It finds no evidence of significant movement of bank deposits into these CBDCs, in part because they are used primarily as payment instruments rather than savings vehicles, and most transactions incur no fees for consumers or merchants, implying potential cost savings versus traditional alternatives. Each jurisdiction’s design reflects distinct policy goals—such as financial inclusion and payments modernization—implemented via two‑tier, account‑based structures with streamlined onboarding for the unbanked and a range of incentives to spur user and merchant adoption. The study underscores that clear public communication, market‑based incentives to secure private sector participation, and international peer learning are critical for success, and that while CBDCs still represent only a small share of total payments, they fill specific gaps and offer useful lessons for global policymakers.

Point-of-Sale Integration: The Hidden Catalyst to CBDC Adoption
Point-of-Sale Integration: The Hidden Catalyst to CBDC Adoption
OMFIF interviewed G+D's Lars Hupel, who emphasizes that for central bank digital currencies (CBDCs) to be widely adopted, seamless point-of-sale (POS) integration is essential. Rather than building new hardware, he suggests leveraging current POS devices and card payment infrastructures, updating them with software for CBDC compatibility. A key to merchant acceptance is providing commercial incentives like lower transaction or scheme fees, rather than relying on regulations such as mandatory acceptance. For users, CBDC payments should be as intuitive as current digital payments, prioritizing convenience and instant, possibly offline, settlement. Ultimately, Dr. Hupel argues that easy technical and commercial integration at POS is the hidden, but critical, catalyst for CBDC adoption, promising greater resilience and efficiency in retail payments.

Results of the 2024 BIS survey on central bank digital currencies
The Bank for International Settlements (BIS) published its annual central bank digital currency (CBDC) survey. It found that 91% of the 93 central banks surveyed were actively exploring CBDCs in 2024, with wholesale CBDC development generally more advanced than retail versions. The primary motivation remains preserving the role of central bank money amid declining cash usage and rising asset tokenization, with over one-third of central banks accelerating their CBDC work in response to stablecoin developments. Significant differences exist between advanced economies and emerging market economies in terms of legal frameworks, design features, and use cases—with emerging economies more likely to have clear legal authority and consider features like distributed ledger technology. Simultaneously, 67% of jurisdictions now have enacted or are developing regulations for stablecoins and cryptoassets, while asset tokenization has gained traction in most advanced economies and one-third of emerging markets, particularly in bond markets, suggesting a coordinated evolution of both public and private digital money initiatives.​​​​​​​​​​​​​​​​ [Read more at the BIS]

Personal financial planning and the propensity of CBDC adoption
Personal financial planning and the propensity of CBDC adoption
A paper published in the International Journal of Bank Marketing explores how personal financial planning impacts individuals’ willingness to adopt central bank digital currencies (CBDCs), using survey data from Sweden and the UK. The research finds that individuals who engage in activities such as budgeting, tracking expenses or setting long-term goals are more likely to express interest in CBDC adoption. These behaviors, reflecting financial literacy and forward-looking decision-making, align with openness to innovative financial technologies, were strengthened by perceptions of security, safety, and trust in the new technology. Individuals who believe that CBDCs are secure and that their personal data will be protected are significantly more likely to adopt the technology. Socioeconomic factors like education and age, as well as personal attitudes toward technology and risk, also influence adoption.

Public Attitudes Towards CBDC and the Role of Trust in the Central Bank
A forthcoming Bar Ilan University Faculty of Law Research Paper reports on the results of a multi-stage nationally-representatvie survey conducted in collaboration with the Bank of Israel on Israeli attitudes towards a possible digital shekel. The survey revealed that willingness to adopt was strongly correlated with trust in the central bank; respondents who expressed higher trust in the Bank of Israel were much more likely to intend to use the digital shekel. Interestingly, concerns about privacy were lower among Israelis compared to similar surveys in other countries, which may explain their relatively high acceptance. When asked about the most important features, respondents prioritized ease of use across payment scenarios, fraud protection, the ability to use the currency offline, absence of hidden fees, the option to earn interest, and above all, assurance that the central bank would not have access to personal transaction data. Overall, the survey highlights that while technical features matter, trust in the central bank is the most decisive factor influencing public willingness to adopt CBDC in Israel.

Digital Dollar: Privacy and Transparency Dilemma
Digital Dollar: Privacy and Transparency Dilemma
The University of California (UC) Law Journal published a paper by Jiaying Jiang that explores the debate around implementing central bank digital currency (CBDC), focusing on the tension between privacy and regulatory demands. The author argues that the prevailing fear of government surveillance is not a technical inevitability but a result of outdated anti-money laundering (AML) and countering the financing of terrorism (CFT) regulations. To address this, the paper proposes concrete solutions: modernizing AML/CFT rules to allow for limited, threshold-based anonymity in everyday CBDC transactions; updating institutional record-keeping and reporting so small or low-risk transfers can occur privately; adopting privacy-preserving technologies like token-based payment options and encryption; and introducing clear legal carve-outs that permit financial institutions to implement privacy-by-design features without breaching regulatory obligations. These reforms, the author contends, would enable a digital dollar that protects user privacy while still equipping authorities with the tools necessary for oversight and crime prevention—demonstrating that privacy and compliance can be achieved together through thoughtful legal and technical innovation.

Threshold Signatures for Central Bank Digital Currencies
Threshold Signatures for Central Bank Digital Currencies
Several G+D researchers published an evaluation of the use of threshold elliptic curve digital signature algorithm (ECDSA) signatures to harden key management in central bank digital currency (CBDC) systems, using G+D’s Filia as a case study. It motivates TSS to eliminate single points of failure in custodial wallets run by financial service providers (FSPs), and compares two integration options, selecting a separate key management network (KMN) that holds key shares and serves signing to Payment Processors for modularity and security. After defining CBDC-driven requirements (transparent coexistence with standard wallets, efficient DKG, high signing throughput, secure key export/import and key updates, compatibility with P-256 ECDSA, and strong composable security), the authors choose the CGGMP21 protocol (via the dfns Rust library) for its UC security, P-256 support, pre-signing, and one-round online signing. Benchmarks show DKG, pre-signing, and signing costs grow with threshold size; end-to-end tests integrating KMN into Filia reveal roughly an order-of-magnitude throughput drop versus non-threshold setups, especially for cross-FSP transfers, though performance is acceptable for smaller n and t. Identified bottlenecks include interactive signing when pre-signatures are unavailable after key updates; proposed mitigations include background pre-signing and persistent channels. The conclusion is that TSS meaningfully strengthens CBDC security and is feasible for real deployments with careful engineering and parameter choices.
