130 Countries, One Goal: The CBDC Race and What Digital Currencies Mean for Tech

The global monetary system is undergoing its most significant transformation in decades. According to the Bank for International Settlements (BIS), 130 countries — representing 98% of global GDP — are now actively exploring central bank digital currencies (CBDCs). That number was just 35 in 2020. The race is no longer a question of if governments will issue digital money; it is a question of how fast, and what the technical choices made today will mean for banks, payment processors, and the entire fintech ecosystem for the next generation.

China’s Digital Yuan: The Benchmark Everyone Is Watching

No country has moved further or faster than China. The e-CNY (digital yuan) pilot, which began quietly in 2020, has now reached a scale that commands global attention. As of early 2026, China has issued over 1.8 billion e-CNY wallets across 26 major cities, with cumulative transaction volumes surpassing 7 trillion yuan (approximately $970 billion). That figure makes the digital yuan the largest CBDC deployment in history by an enormous margin.

What makes e-CNY technically notable is not just the scale — it is the architecture. China’s system operates on a two-tier model: the People’s Bank of China (PBOC) issues digital yuan to commercial banks, which then distribute it to consumers and businesses through existing banking infrastructure and apps. Crucially, e-CNY does not use a public blockchain. It runs on a centralized distributed ledger controlled entirely by the PBOC, giving the state full visibility into transaction flows and the ability to attach programmable conditions to money — something no commercial bank can currently offer.

The implications for international trade are significant. China is already piloting mBridge, a cross-border CBDC platform built with the BIS Innovation Hub, connecting the digital yuan with Hong Kong, Thailand, and the UAE. If mBridge scales, it offers a dollar-bypass corridor for trade settlement that could reshape the architecture of global payments.

The EU Digital Euro: Cautious, Privacy-Focused, Politically Contested

The European Central Bank (ECB) is moving more carefully. After completing its investigation phase in late 2023, the EU entered a formal preparation phase in 2024 that is expected to run through 2026 before any legislative decision. A retail digital euro — money held directly by citizens, not banks — remains the stated goal, but the politics are genuinely complicated.

European banks have lobbied hard against a digital euro that would allow consumers to hold large balances directly with the ECB, arguing it would trigger deposit flight from commercial banks during economic stress events. In response, the ECB has proposed a holding limit of €3,000 per individual — enough for everyday payments, not enough to replace a bank account. Privacy advocates, meanwhile, have pushed back on any design that gives central banks transaction-level visibility into citizen spending.

The ECB’s proposed solution is “conditional anonymity”: small everyday payments would be processed without identifying data (similar to cash), while larger or suspicious transactions would be flaggable. Whether this satisfies privacy law under GDPR remains an open legal debate.

From a technology perspective, the digital euro architecture leans on an intermediated model — commercial banks and payment service providers remain in the loop — rather than a direct CBDC design. The underlying ledger is not public; it is a permissioned system managed by the ECB and its national bank partners.

The United States: FedNow vs. CBDC

The US position is notably more ambiguous than either China or the EU. The Federal Reserve launched FedNow in July 2023 — an instant payments infrastructure that allows real-time bank-to-bank settlement 24/7. FedNow is not a CBDC; it is a faster rail for existing bank money. But for many practical use cases — instant payroll, real-time bill payment, emergency disbursements — it addresses the same pain points that CBDC proponents cite.

Political headwinds against a US retail CBDC have stiffened considerably. Legislation introduced in Congress would explicitly prohibit the Federal Reserve from issuing a retail CBDC without congressional authorization, citing surveillance concerns. The current administration has signaled it has no plans to advance a digital dollar. The US financial industry, which benefits enormously from correspondent banking fees and dollar-denominated settlement, has little commercial incentive to accelerate a disruptive alternative.

Where the US remains actively engaged is in wholesale CBDC research — digital dollars used only between financial institutions for interbank settlement, not accessible to consumers. Project Cedar, run by the New York Fed, has shown that wholesale CBDC transactions can settle in under 10 seconds across currency pairs, compared to the 2–5 days typical of correspondent banking today.

Nigeria’s eNaira: Hard Lessons from an Early Mover

Nigeria launched the eNaira in October 2021, becoming the first African country to issue a CBDC. The results have been sobering. Adoption remained stubbornly low for two years despite government incentives, with fewer than 1% of Nigerians using the eNaira regularly as of mid-2023. The Central Bank of Nigeria redesigned the app twice, removed transaction fees, and linked the eNaira to Nigeria’s National ID system in an attempt to drive uptake.

The failure mode was not technical — the eNaira worked as designed. The failure was behavioral and trust-based. Nigerians who already transacted digitally used established fintech apps like OPay and Flutterwave. Those who remained unbanked lacked smartphones or reliable data connectivity. The eNaira sat between these two groups, solving a problem that neither group had articulated as their own.

The lesson for CBDC designers globally: technology is the easy part. Distribution, trust, and genuine utility against incumbent alternatives are the hard parts.

The Tech Stack: Distributed Ledger vs. Centralized Architecture

Across the 130 countries studying CBDCs, two broad architectural philosophies have emerged. The first — exemplified by China — uses a centralized or permissioned distributed ledger where the central bank retains full control. This maximizes programmability and state oversight but creates a single point of failure and raises civil liberties concerns.

The second approach, explored by countries like Canada and Sweden, experiments with more decentralized architectures that give greater autonomy to commercial banks and payment processors in operating the CBDC infrastructure. These models are slower to deploy but politically easier to adopt in democratic systems where central bank overreach is constrained by law.

Programmable money — the ability to attach conditions to currency (expiry dates, restricted merchant categories, spending triggers) — is perhaps the most disruptive capability that CBDCs introduce. It raises profound questions about monetary sovereignty, individual freedom, and the appropriate role of the state in regulating how money flows.

What This Means for Banks and the Payments Industry

For commercial banks, CBDCs represent a structural threat and a structural opportunity simultaneously. If consumers hold CBDC wallets directly with central banks, the deposit base that underpins bank lending shrinks. But if banks serve as CBDC distributors — as in both the EU and China’s two-tier models — they remain essential infrastructure.

For payment processors and card networks, the risk is more direct. Visa and Mastercard currently earn billions from interchange fees on every card swipe. A CBDC that enables peer-to-peer or merchant payments without going through card rails would compress that revenue significantly. Both companies are investing heavily in CBDC integration research, seeking to position themselves as wallet and API layer providers in the new infrastructure rather than being bypassed entirely.

Fintech startups face the most complex environment: CBDC infrastructure could either eliminate the problem they were built to solve (expensive, slow money movement) or become the foundational layer on which a new generation of financial applications is built.
