Sovereign Digital Currencies and the Remaking of Emerging Market Economies by 2035

Research Brief: How Sovereign Digital Currencies Could Redefine Emerging Market Economies by 2035 Prepared by: SANICE AI — Glass Research Pipeline Date: May 25, 2026

Executive Synthesis

The global CBDC landscape in 2025 presents a structural paradox: the countries with the most to gain from sovereign digital currencies are frequently the least equipped to capture those gains. Early-mover emerging economies demonstrate that CBDC deployment does not automatically generate financial inclusion — it generates infrastructure upon which inclusion can be built, but only if the design, governance, and ecosystem integration are deliberately engineered from the outset. The window for consequential design decisions is 2025–2028; the architecture choices made in that period will determine which version of the 2035 CBDC landscape materializes — one of expanded inclusion and monetary efficiency, or one of surveillance normalization and entrenched inequality. Policymakers, institutional investors, and development practitioners who treat CBDC governance as a central bank operational matter rather than a constitutional-level policy question are systematically mispricing the strategic stakes.

Defining Sovereign Digital Currencies and Their Relevance to Emerging Markets

A Central Bank Digital Currency is a direct liability of a sovereign monetary authority, denominated in the national unit of account, and distributed through digital infrastructure. Unlike cryptocurrencies, a CBDC carries the full faith and credit of the issuing state. Unlike commercial bank deposits, it does not carry counterparty risk against a private institution. This distinction matters enormously in emerging markets, where banking system fragility and sovereign credit risk are often inversely correlated — precisely the environments where a well-designed CBDC offers the greatest theoretical advantage.

Emerging markets, broadly defined, encompass economies in Sub-Saharan Africa, South and Southeast Asia, Latin America, Central Asia, and parts of the Middle East. They share structural characteristics that are directly relevant to CBDC design considerations:

• Large unbanked or underbanked populations with limited access to formal financial services
• High remittance dependency, with flows often exceeding foreign direct investment in GDP terms
• Underdeveloped payment infrastructure relative to mobile device penetration
• Limited fiscal space for conventional monetary interventions
• Asymmetric integration into global financial systems, concentrated through dollar-denominated correspondent banking

These are not peripheral conditions. They are the fault lines along which CBDCs could, if properly designed and deployed, generate transformative economic impact by 2035. The operative word remains "could." This report does not argue that CBDCs will automatically redefine these economies. The evidence consistently supports a more conditional path — one in which design choices, governance frameworks, and political economy dynamics determine whether sovereign digital currencies become instruments of inclusion or vectors of surveillance and exclusion.

Current Global Landscape: CBDC Development Tiers and Active Deployments

The global CBDC development landscape in 2025 is better characterized as a stratified ecosystem than a uniform wave of adoption. A significant number of central banks worldwide are in exploratory, development, or live stages, but meaningful operational progress remains highly concentrated among a subset of actors.

Among emerging economies, three tiers of engagement are visible:

Live retail deployments: Nigeria's eNaira, Jamaica's JAM-DEX, and the Bahamas' Sand Dollar represent first-generation retail CBDCs. Their common characteristic is modest uptake, attributed to limited merchant acceptance, inadequate offline functionality, and insufficient integration with existing payment habits. These systems are functioning proofs of concept, but not yet evidence of transformational impact.

Advanced pilots with scale ambitions: India's digital rupee (e₹) has achieved a circulation of ₹1,016 crore (approximately USD 122 million) as of March 2025, with announced plans for cross-border CBDC pilots. China's e-CNY has been extended to Hong Kong in 2025, creating what is reported as the world's first linkage between a Fast Payment System and a CBDC — a structurally significant development for understanding interoperability architecture and its geopolitical implications.

Full-launch completions: Kazakhstan was scheduled to complete the full launch of its Digital Tenge by end of 2025, with a design emphasizing programmability and cross-border payment functionality. This positions Kazakhstan as a critical case study for how Central Asian economies navigate CBDC deployment in resource-dependent, dollarized environments.

Scale: 1 = Early Exploration, 3 = Live Pilot, 4 = Advanced/Expanding, 5 = Full Operational Rollout

Research examining CBDC adoption across a broad sample of countries finds that existing financial inclusion indicators — specifically account ownership rates — positively correlate with the likelihood of a country advancing to a CBDC pilot project. This is counterintuitive on the surface but reveals a critical structural truth: CBDC adoption correlates with existing financial infrastructure, not the absence of it. Countries with the deepest financial exclusion problems may paradoxically face the highest barriers to CBDC deployment — a self-reinforcing gap that requires deliberate policy intervention to break.

The IMF's CBDC Virtual Handbook, with new chapters published November 2025 and financially supported by the Government of Japan, represents the most comprehensive multilateral technical resource currently available for emerging market and developing economy central banks. Its existence signals that the international institutional architecture around CBDC governance is maturing — but technical guidance alone cannot substitute for political will and domestic institutional capacity.

Economic Redefinition: Financial Inclusion, Remittances, and Monetary Policy

Financial inclusion remains the most frequently cited justification for CBDC development in emerging markets — and the evidence on whether it will be delivered remains genuinely mixed. The UNDP's January 2025 analysis identifies the design features that make financial inclusion outcomes achievable:

• Offline functionality enabling transactions in low-connectivity environments
• Simplified Know-Your-Customer (KYC) requirements for low-risk, low-value transactions
• User interfaces calibrated for low-literacy populations
• Interoperability with mobile money ecosystems already operating at scale

Without these features, a CBDC is effectively a digital product for the already-banked. With them, the addressable population expands dramatically. Sub-Saharan Africa alone has mobile penetration rates that significantly outpace bank account ownership — the infrastructure for CBDC distribution exists in the handset, not the branch.

On remittances, the structural opportunity is substantial. Remittance flows to low- and middle-income countries represent a significant share of GDP in many emerging economies — in some cases exceeding foreign direct investment and official development assistance combined. The cost of sending remittances has traditionally remained high in corridor-specific markets, well above internationally recognized targets. A well-designed cross-border CBDC rail — particularly one leveraging the interoperability architectures being developed through BIS Innovation Hub projects like mBridge — could structurally reduce these costs toward near-zero marginal transaction fees.

The critical constraint is that cross-border CBDC interoperability requires bilateral or multilateral agreements between sovereign monetary authorities. This is inherently a political negotiation, not a technical one. The e-CNY extension into Hong Kong's Fast Payment System is significant precisely because it demonstrates that a major economy is willing to establish the precedent — and China's geopolitical incentives for doing so in Belt and Road corridor economies deserve rigorous analytical attention.

Monetary policy implications are the most underappreciated dimension of this transition. A retail CBDC that achieves significant scale introduces a structurally new variable into monetary transmission. Central banks gain the potential for:

• Direct fiscal transfer capability (programmable stimulus payments with consumption parameters)
• Real-time visibility into transaction velocity and sectoral spending patterns
• Potential disintermediation of commercial banking deposit bases

The disintermediation risk is particularly acute in emerging markets where commercial banks rely more heavily on deposit funding and have thinner capital buffers. If a CBDC is perceived as safer than a commercial bank deposit — a perception entirely rational in environments with a history of banking crises — deposit flight becomes a systemic vulnerability. This is not hypothetical: it is the core reason why most CBDC designs currently include holding limits (caps on individual CBDC balances) as a structural safeguard.

The design tension between inclusion (maximize accessibility) and stability (limit substitution) cannot be resolved by technical means alone. It requires explicit policy choices that must be made before deployment, not after.

Challenges and Risks: Infrastructure, Digital Divide, and Financial Stability

The gap between CBDC ambition and operational reality across emerging economies reflects compounding implementation challenges that deserve honest, disaggregated treatment.

Technological infrastructure constraints are the most visible but least analytically distinctive challenge. More structurally significant is the governance capacity gap: running a CBDC system requires central banks to develop competencies in software engineering, cybersecurity, data architecture, and real-time system operations — disciplines that are adjacent to, not part of, traditional central banking. The IMF's technical assistance infrastructure is scaling to address this, but the timeline required to build institutional capacity across dozens of central banks simultaneously is measured in years, not months.

The digital divide operates on multiple axes simultaneously:

• Device access (smartphone penetration versus feature phone environments)
• Connectivity (urban 4G/5G versus rural 2G or no-signal zones)
• Digital literacy (ability to navigate wallet interfaces and manage PINs)
• Trust (population confidence in state-issued digital instruments, particularly in countries with histories of currency crises or government seizure of assets)

The trust dimension is systematically underweighted in technical CBDC literature. In Zimbabwe, Venezuela, or Argentina — environments where citizens have experienced forced currency conversions, hyperinflation, or capital controls — the state's issuance of a new digital currency will be met with structural skepticism that no technical elegance resolves. Adoption requires social legitimacy, and social legitimacy must be earned through demonstrated monetary policy credibility over time.

Financial stability risks manifest through several transmission channels:

• Bank disintermediation reduces credit creation capacity if commercial deposits migrate to CBDC holdings at scale
• Cybersecurity vulnerabilities in centralized CBDC infrastructure create single-point-of-failure risks at the sovereign level — a breach of a CBDC ledger is not a private bank breach, it is a monetary system breach
• Currency substitution dynamics in dollarized or informally euroized economies could be disrupted in ways that benefit long-run sovereignty but create short-term volatility

The IMF's November 2025 paper explicitly acknowledges that low adoption in early-implementing countries reflects inadequate attention to demand-side and trust-side factors. The lesson from Nigeria's eNaira is not that CBDCs don't work — it is that they don't work by default. Adoption requires deliberate ecosystem development: merchant incentive programs, integration with government payment flows, and mobile operator partnerships that treat CBDC wallets as an on-ramp rather than a competing product.

Geopolitical and Social Implications: Data Sovereignty, Global Trade, and Governance by 2035

By 2035, the geopolitical architecture of sovereign digital currencies will be at least as consequential as their domestic economic impacts. The international CBDC landscape is already stratifying along three distinct governance models:

1. State-centric surveillance architectures — exemplified by China's e-CNY design, which provides transaction-level visibility to monetary authorities. The e-CNY's expansion into Hong Kong and its integration potential across Belt and Road economies represents a genuine geostrategic vector. For emerging market economies that adopt China's CBDC technical standards or interoperability protocols, the data sovereignty implications are significant: transaction flows become visible to a foreign sovereign authority. This is not speculative — it is the structural consequence of protocol-level dependencies.

2. Privacy-preserving architectures — advocated by the European Central Bank's digital euro design and BIS working group guidance, these systems seek to preserve tiered anonymity: full privacy for small transactions, identity verification for larger flows. For emerging market central banks choosing technical partners and architecture models, this choice is largely irreversible in the medium term. The standard adopted during the pilot phase becomes the infrastructure upon which the national payment system is built.

3. Federated or multilateral architectures — projects like mBridge (BIS-facilitated, involving central banks of China, Hong Kong, Thailand, and the UAE) and Project Dunbar represent attempts to build shared rails that distribute governance across participating sovereigns. For smaller emerging economies, multilateral rails offer reduced technical burden but introduce new dependencies on the norms and power dynamics of the governing consortium.

Data sovereignty is a first-order geopolitical issue, not a technical footnote. A central bank's CBDC system contains, in aggregate, a near-complete map of its economy: who transacts with whom, in what amounts, on what schedule, and in what sectors. For economies seeking to preserve strategic autonomy — particularly those navigating U.S. sanctions pressure, IMF conditionality, or Chinese economic influence simultaneously — the architecture of their CBDC system is an act of geopolitical alignment as much as monetary policy.

For global trade, CBDC networks could reduce the structural dominance of the U.S. dollar correspondent banking system. The traditional SWIFT-based correspondent banking model creates significant friction for emerging market trade — particularly for intra-regional trade between developing economies. A bilateral CBDC settlement system between two African central banks could in principle enable direct settlement in local currencies without dollar intermediation. The political will to pursue this exists in several regional contexts; the technical infrastructure and bilateral trust architecture do not yet.

Social governance dimensions introduce a further layer of complexity. Programmable money — CBDCs with embedded spending conditions or expiry dates — enables genuinely novel social policy instruments: conditional cash transfers that can only be spent on food, education, or healthcare; stimulus payments that expire if unspent within a defined window to maximize velocity. These capabilities are real policy tools. They are also instruments of financial control that, in authoritarian contexts, can enforce ideological compliance through monetary mechanism. The governance frameworks that constrain programmatic capabilities are therefore not regulatory details — they are human rights considerations.

By 2035, the emerging market economies that navigate these trade-offs successfully will have done so by treating CBDC governance as constitutional-level policy, not central bank operational design.

Strategic Outlook: Conditions for Transformational Impact by 2035

The evidence supports a forward projection in which CBDC adoption across emerging market economies will be widespread but deeply uneven in impact by 2035. The countries that realize transformational gains will be distinguishable not by the sophistication of their technology, but by the clarity of their institutional design and the depth of their stakeholder integration.

On financial inclusion architecture: Effective CBDC systems must be designed for the last-mile user from the outset. Retrofitting offline capability, low-literacy interfaces, and tiered KYC onto an already-deployed system is technically expensive and politically difficult. India's e₹ pilot, at USD 122 million in circulation as of March 2025, offers the most relevant near-term empirical dataset on what design features drive adoption in a large, diverse emerging market — this evidence base should be systematically analyzed before domestic architecture decisions are finalized elsewhere.

Interoperability with existing mobile money ecosystems — M-Pesa-class infrastructure in Africa, GoPay and Dana ecosystems in Southeast Asia — is not optional for emerging markets seeking meaningful adoption. CBDC systems that compete with established mobile money networks face entrenched adoption barriers; those that complement them gain instant distribution scale.

On monetary policy safeguards: Structural holding limits and remuneration policies must be implemented from launch, not as post-hoc corrections. The disintermediation risk to commercial banks is manageable if contained by design, but asymmetrically damaging if allowed to develop organically. Real-time monetary monitoring capabilities must be developed in parallel with CBDC deployment — the data advantage of a CBDC system only translates into policy advantage if the central bank has the analytical infrastructure to process transaction-level data for macroprudential purposes.

On cross-border architecture: BIS multilateral initiatives — mBridge and Nexus — represent priority technical partnerships for smaller emerging economies, for whom the development cost of bilateral interoperability agreements with every relevant trade partner is prohibitive. The Kazakhstan Digital Tenge model warrants specific analysis for programmable cross-border payment applications, representing the most directly analogous case study for other Central Asian and resource-dependent economies.

The structural forecast for 2035: Emerging market economies with populations above 50 million, functional digital identity infrastructure, mobile penetration above 70%, and central banks with existing payments modernization programs are the highest-probability candidates for CBDC systems that demonstrably advance financial inclusion and monetary efficiency. For smaller, lower-infrastructure economies, the realistic near-term path is integration into regional multilateral CBDC rails rather than standalone national systems — a trade-off of sovereignty for access that is analytically defensible given the cost and capacity constraints involved.

The design choices made between 2025 and 2028 will determine which future materializes.

⚠️ Governance Capacity Shortfalls: The Hidden Implementation Risk

The successful implementation of CBDCs in emerging markets hinges on governance capacity, which is consistently and dangerously underestimated in both technical literature and policy planning. Countries with limited institutional frameworks may struggle to develop the required competencies in cybersecurity, data management, real-time operations, and monetary analytics — disciplines that are adjacent to traditional central banking, not part of it. A CBDC system deployed without this capacity is not merely inefficient; it is a liability. A centralized digital monetary ledger without robust cybersecurity is a single point of failure at the national monetary system level — an attack surface that did not exist under conventional payment architectures.

• Severity: High
• Mitigation: Engage proactively in international collaborations for capacity building — the IMF's CBDC Virtual Handbook and BIS Innovation Hub resources represent the current state of multilateral technical assistance. Leverage regional partnerships to share resources, expertise, and infrastructure where national capacity constraints are binding. Prioritize sequencing: do not deploy a live retail CBDC until internal governance capacity meets minimum operational standards, even if this means delaying launch timelines relative to peer economies.

💡 Leverage Mobile Money Networks: The Underutilized Acceleration Path

Existing mobile money networks — M-Pesa in East Africa, bKash in Bangladesh, GoPay and Dana in Southeast Asia — represent the single most underutilized resource in emerging market CBDC strategy. These networks already carry the user relationships, distribution infrastructure, and behavioral trust that CBDC systems are attempting to build from scratch. Integrating CBDCs into these platforms rather than positioning them as competing products converts an adoption challenge into a distribution opportunity. The user base is already there; the question is whether the architecture connects to it.

• How to Apply: Initiate formal negotiations and technical integration discussions with major mobile money providers to create integrated platforms that accept CBDCs, focusing on seamless user experiences that require no behavioral change from existing users. Treat mobile money operators as distribution partners, not competitors, in national CBDC rollout strategies.
• Why This Matters: Many countries are pursuing CBDC deployment as a standalone system build, viewing sovereign digital currency as categorically separate from existing fintech infrastructure. This is a strategic error. Countries that recognize CBDCs as a complement — not a replacement — to existing mobile financial ecosystems will achieve adoption curves orders of magnitude faster than those that do not. First movers in this integration approach will establish network effects that become structurally difficult for later entrants to replicate.

🧭 Execution Plan: From Strategy to Implementation

1. Refine CBDC Design Specifications (Complete within the current institutional planning cycle)

   • What to do: Conduct systematic, in-depth analysis of current pilot projects — particularly India's e₹ and the Nigeria eNaira — focusing on the specific design features that drive or inhibit adoption: offline functionality, tiered KYC, mobile operator integration, and merchant acceptance infrastructure. Document design requirements before architecture decisions are finalized.
   • Why now: Early-stage architecture decisions are effectively irreversible within a 5–10 year horizon. Analysis of existing pilots provides an empirical foundation that eliminates the most costly category of error: deploying the wrong design at scale.

2. Build Institutional Capacity (Initiate within the next budget and staffing cycle)

   • What to do: Establish structured training programs within central banks covering cybersecurity fundamentals, data management and architecture, and real-time monetary operations. Engage with IMF technical assistance programs and BIS Innovation Hub resources as external capacity accelerators. Set minimum internal governance standards as a deployment prerequisite.
   • Why now: Governance capacity cannot be built after deployment. The time between CBDC planning and go-live — typically measured in years — is the only window in which institutional capability can be developed without operational risk exposure.

3. Develop Stakeholder Engagement Framework (Begin formal consultation within the next policy planning cycle)

   • What to do: Engage commercial banks, mobile money operators, fintech companies, consumer advocacy groups, and privacy regulators in structured consultation processes to align CBDC rollout design with existing financial ecosystems and public expectations. Publish architecture choices — including foreign technical dependencies and data access provisions — with full transparency, subject to appropriate legislative scrutiny.
   • Why now: Stakeholder resistance from commercial banks and mobile operators, if unmanaged, can create distribution bottlenecks that no technical solution resolves. Early engagement converts potential opponents into implementation partners — and the window for this alignment closes once deployment parameters are publicly committed.
