"From the second phase, we will lay the groundwork for commercialization." — Bank of Korea representative, on Project Hangang Phase 2
Three of the world's largest economies have adopted mutually incompatible central bank digital currency strategies in the span of six months. The United States signed a four-year legal prohibition on Federal Reserve digital dollar issuance on July 10, 2026. South Korea announced the same week that it will expand Project Hangang to nine banks with live retail transactions beginning September 2026. China, meanwhile, reclassified the e-CNY from central bank cash to commercial bank deposit liability in January 2026 — effectively abandoning the CBDC model it pioneered.
The result is a fractured global landscape. According to the Atlantic Council CBDC Tracker, 146 countries representing 98% of global GDP are exploring digital currencies, with 41 active pilot programs. Yet the three largest potential markets — the US ($26.9T GDP), China ($18.5T), and South Korea ($1.7T) — are now moving in fundamentally different directions. The divergence has implications for cross-border settlement architecture, stablecoin regulation, and the competitive positioning of private-sector payment networks.
The US Senate passed the 21st Century ROAD to Housing Act on June 22, 2026, in an 85–5 vote. Buried within the housing-affordability legislation was Section 4021, which prohibits the Board of Governors of the Federal Reserve System or any Federal Reserve bank from issuing "a central bank digital currency or any digital asset that is substantially similar" — directly or through intermediaries — until December 31, 2030.
The bill became law on July 10, 2026, when President Trump signed it into effect. The prohibition formalized an executive order signed in January 2025 that had already halted administrative CBDC work.
The legislative ban does not apply to privately issued stablecoins. The GENIUS Act, a separate piece of legislation governing stablecoin issuance and reserves, passed both chambers but missed its July rulemaking deadline, with six federal agencies failing to publish required implementing regulations by the statutory cutoff.
The practical effect is a policy architecture that favors private-sector digital dollar issuance — via USD-pegged stablecoins regulated under the GENIUS Act — over a sovereign digital currency. Kevin Warsh, President Trump's Federal Reserve nominee, had previously characterized China's e-CNY project as threatening "the dominance of the US dollar," framing the prohibition as a defensive posture rather than technological aversion.
The Bank of Korea (BOK) on July 20, 2026, confirmed the second phase of Project Hangang will begin live retail transactions in September 2026 with nine participating commercial banks. The architecture uses a two-tier model: the BOK issues wholesale CBDC on its own infrastructure, while commercial banks mint and manage deposit tokens backed by the digital won for consumer use.
Phase 1 ran for approximately three months beginning April 2025. The results were modest:
| Metric | Result | |--------|--------| | Invitations sent | 100,000 | | Wallets opened | ~80,000 | | Test transactions | 118,000 | | Transaction volume | 692.46 million won (~$500,000) | | Infrastructure spend (banks) | 30–35 billion won (~$21–25 million) |
The cost-to-volume ratio was unfavorable. Banks collectively spent roughly 43–50x the transaction volume on infrastructure. Only 80% of invited participants opened wallets, and average transaction size was approximately 5,900 won ($4.25).
Phase 2 adds Kyongnam Bank and iM Bank to the original seven participants: KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup, IBK Industrial, and BNK Busan Bank. LG CNS remains the core technology partner.
New capabilities include biometric (fingerprint) authentication, peer-to-peer wallet transfers, and automatic top-up from linked bank accounts — features absent from Phase 1 that the BOK identified as barriers to adoption.
Unlike Phase 1's fixed three-month window, Phase 2 has no predetermined end date, signaling the BOK's intent to iterate toward commercialization rather than run bounded experiments.
The BOK plans to test deposit tokens as a distribution channel for government subsidies, beginning with the Ministry of Climate, Energy and Environment's EV Charging Facility Construction Programme. The 2026 program allocation is approximately 30 billion won (~$21 million). If successful, the BOK has indicated interest in channeling a portion of South Korea's 110 trillion won annual subsidy disbursements through the CBDC rail.
Separately, the Ministry of Economy and Finance is preparing a tokenized government bond pilot using the wholesale CBDC settlement layer, targeted for Q4 2026 in Sejong, the administrative capital.
On January 1, 2026, the People's Bank of China (PBOC) reclassified the e-CNY from a direct central bank liability — the standard CBDC model — to a commercial bank deposit liability. The change, analyzed by the Peterson Institute for International Economics (PIIE), effectively means the e-CNY is no longer a CBDC by conventional definitions.
Under the new framework:
The Japan Research Institute assessed that, following this change, the digital yuan "resembles tokenized deposits more closely than a conventional CBDC."
Despite operating the world's largest retail digital currency pilot across 26 cities, the e-CNY's market penetration remains marginal:
| Metric | Value | |--------|-------| | Cumulative transactions | 3.5 billion | | Cumulative volume | 16.7 trillion yuan (~$2.3 trillion) | | 2024 annual volume | 4.2 trillion yuan | | Share of China's digital payment volume | 0.2% |
The 0.2% share is the critical figure. Alipay and WeChat Pay processed over 2,100 trillion yuan in digital payments in 2024. The e-CNY, despite seven years of development and integration with both platforms, has failed to capture meaningful market share.
The PIIE analysis noted a structural tension: payment platforms must hold 100% reserves and cannot pay interest on digital wallet balances, while retail banks can offer interest on e-CNY deposits. The interest rate differential — 0.05% on e-CNY deposits versus up to 3.5% on US stablecoin yields — illustrates the competitive gap.
The European Central Bank completed its two-year preparation phase for the digital euro in October 2025 and approved continuation into a pilot development phase beginning Q3 2026. A call for expressions of interest from European payment service providers will launch in 2026, with an operational pilot expected in H2 2027 for a 12-month period.
The ECB has stated it will only decide whether to issue a digital euro once the European Parliament and Council adopt the Digital Euro Regulation, currently in legislative process. The earliest possible issuance is 2029, contingent on regulation adoption in 2026 — a timeline that has already slipped.
Design parameters include offline payment capability, privacy protections for low-value transactions, and per-wallet holding limits to prevent disintermediation of commercial banks. The architecture explicitly prioritizes bank stability over adoption velocity.
The fracture in domestic CBDC strategies directly affects cross-border settlement infrastructure. Project mBridge — the multi-CBDC platform linking central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia — has processed $55.49 billion across 4,047 transactions, a 2,500-fold increase from 2022 pilots. China's e-CNY accounts for over 95% of mBridge settlement volume.
The Bank for International Settlements (BIS) withdrew from mBridge governance in October 2024, transferring control to the participating central banks. The project's Chinese dominance and the BIS exit have raised questions about its viability as a neutral multilateral platform. A Forbes analysis in May 2026 declared multilateral CBDC interoperability "dead" following the governance changes.
The US prohibition on a Federal Reserve CBDC means there will be no American participant in cross-border CBDC settlement networks through at least 2031. This creates a structural gap that private-sector stablecoins — USDC, USDT, and potentially bank-issued tokens — may fill by default rather than by design.
South Korea's wholesale CBDC layer, by contrast, is being designed with cross-border extensibility. The Seoul Economic Daily reported on July 1, 2026, that the BOK is exploring using Project Hangang infrastructure for foreign bond investment settlement, suggesting an ambition beyond domestic retail payments.
| Dimension | United States | South Korea | China | Eurozone | |-----------|--------------|-------------|-------|----------| | Status | Legally banned until 2030 | Phase 2 pilot (Sep 2026) | Reclassified as deposit token | Pilot development (2027) | | Architecture | N/A (stablecoins preferred) | Wholesale CBDC + deposit tokens | Commercial bank deposit liability | TBD (offline + privacy focus) | | Retail users | N/A | ~80,000 (Phase 1) | 26 cities, 0.2% penetration | N/A | | Cross-border | None planned | Hangang extensibility explored | mBridge ($55.49B settled) | None active | | Interest-bearing | N/A | Not specified | Yes (bank deposit rate) | TBD | | Earliest possible launch | 2031 | 2027 (commercialization) | Live since 2020 (redefined 2026) | 2029 | | Technology partner | N/A | LG CNS | State-owned banks | TBD (RFI in 2026) |
The US has legislated itself out of the CBDC race through 2030. The 85–5 Senate vote signals bipartisan consensus favoring private stablecoin issuance over sovereign digital currency. No Federal Reserve digital dollar project exists to resume even if the ban expires.
South Korea is running the most structurally ambitious retail CBDC pilot among major economies. The two-tier wholesale-CBDC-plus-deposit-token model, government subsidy channel, and tokenized bond pilot represent a full-stack approach. Phase 1 adoption was weak — 692 million won in volume against 30–35 billion won in infrastructure costs — but Phase 2 removes the fixed timeline, allowing indefinite iteration.
China has effectively conceded the CBDC model. Reclassifying e-CNY as a commercial bank deposit means it competes as a bank product, not a monetary instrument. After 3.5 billion transactions and $2.3 trillion in cumulative volume, it commands 0.2% of digital payments. The pivot acknowledges that Alipay and WeChat Pay's dominance cannot be displaced by government mandate.
Europe's digital euro remains a regulatory exercise. The earliest possible issuance in 2029 — contingent on legislation that has not yet passed — means the eurozone will observe the results of other jurisdictions before committing resources.
Cross-border CBDC settlement is fragmenting. mBridge's 95% Chinese dominance, the BIS withdrawal, and the US prohibition collectively undermine the original vision of interoperable sovereign digital currencies. Private stablecoins are the default beneficiary.
The global CBDC project, which the Atlantic Council tracks across 146 countries, has entered a phase of structural divergence rather than convergence. The three largest non-European economies have chosen incompatible paths: prohibition, active deployment, and redefinition. Only South Korea is pursuing the original CBDC model — a central-bank-issued wholesale layer supporting commercial-bank retail tokens — at meaningful scale among major economies.
The economic implications follow directly. In jurisdictions where CBDCs stall or are prohibited, private stablecoins absorb the demand for programmable digital money. In jurisdictions where CBDCs launch but fail to achieve adoption — as China's 0.2% penetration suggests — the infrastructure investment yields regulatory capability rather than commercial returns. South Korea's Phase 2 will test whether the deposit-token model can achieve the adoption that direct CBDC issuance has not.
The data will become clearer by Q1 2027, when South Korea's open-ended pilot will have six months of results, China's reclassified e-CNY will have a full year under the new framework, and Europe's pilot operational phase will be underway. Until then, the fracture is the story.
