The global financial architecture is experiencing a curious paradox. Despite unprecedented regulatory interest in central bank digital currencies (CBDCs), real-world implementation remains more the exception than the rule. To date, 146 countries and currency unions, representing about 98% of global GDP, are actively exploring the potential of state-issued digital money. However, only four jurisdictions have reached full retail circulation: Jamaica, the Bahamas, Kazakhstan, and Nigeria. This is a telling sign that the path from concept to mass adoption is strewn not only with technological but also institutional obstacles.
China takes the lead: the digital yuan as a savings instrument
China remains the undisputed leader in scale. The Middle Kingdom is not merely testing the technology but transforming the digital yuan into a full-fledged financial instrument. Since 2026, the People's Bank of China has expanded the number of operator banks from 10 to 30, and starting January 1, it has begun accruing interest on balances in digital wallets. A rate of 0.05% per annum for verified users is a global precedent. In essence, Beijing is converting a means of payment into a savings instrument, directly challenging traditional bank deposits.
Notably, the Chinese model differs fundamentally from Russian approaches. The digital yuan is promoted not only as a payment method but also as a store of value. In parallel, Beijing is actively developing cross-border settlements, moving some operations beyond SWIFT statistics through independent digital channels. This is a strategic step aimed at strengthening currency sovereignty while bypassing Western payment infrastructure.
Europe in debate, the US in opposition
The European Union is moving significantly slower. The digital euro project has been under development since June 2023, and only in July 2026 did the European Parliament approve its position, opening the final stage of negotiations with the EU Council. The ECB has already selected 36 banks and payment companies, including Deutsche Bank, Revolut, and UniCredit, to participate in the pilot, which is scheduled to begin in the second half of 2027. The testing will last 12 months, with the main disputes revolving around mandatory acceptance, the offline version, data protection, and the risk of deposit outflows from the banking system.
The United States has taken the toughest stance among major economies. In June 2026, Congress passed a law prohibiting the Federal Reserve from issuing a retail digital currency until December 31, 2030. The initiative received overwhelming support: 89 votes to 10 in the Senate and 396 to 13 in the House of Representatives. The reason is obvious — the dominance of the dollar does not require creating an instrument that could undermine the existing system. Research in the country continues, but only in the area of wholesale settlements under the Agorá project involving the New York Fed.
The Korean experiment and the global mosaic of readiness
South Korea demonstrates a different approach. In September 2026, the Bank of Korea is launching the second phase of its pilot across nine commercial banks, connecting real transactions to the testing for the first time. The system's distinctive feature lies in the division of roles: the regulator provides the infrastructure, while each bank issues its own deposit tokens — tokenized versions of deposits. The new head of the regulator, Hyun Song Shin, has already called CBDCs and deposit tokens the most important element of the country's monetary system, relegating private stablecoins to a secondary role.
The remaining economies are distributed across stages of readiness. India, Iran, the UAE, Turkey, and North Korea are conducting pilots at various stages; Brazil, Japan, Indonesia, Thailand, Australia, and Canada are developing concepts; Qatar is at the initial stage of launch. Mongolia and Saudi Arabia have joined the international mBridge project for real-time settlements via distributed ledger. Sweden remains one of the pioneers of research, but it is still far from launch.
My conclusion as an analyst: the gap between pilots and real-world implementation is not a technical problem but a fundamental issue of trust and economic viability. Until CBDCs offer users clear advantages over existing systems, mass adoption will remain more of a political decision than a market necessity. The Chinese model with interest accruals could become the very catalyst that forces others to accelerate.
