The race to develop and deploy central bank digital currencies (CBDCs) is gaining momentum worldwide, with major economies advancing pilot programs, refining technical frameworks, and addressing strategic financial sovereignty concerns. From retail payment trials in South Korea to wholesale system innovations in Switzerland, central banks are actively shaping the future of money—driven by technological evolution, economic security, and the growing influence of private digital payment platforms.
This transformation marks a pivotal shift in global finance, where digital currency is no longer a theoretical concept but a tangible priority for national monetary authorities. As these initiatives progress, they reflect diverse strategies tailored to regional needs, regulatory environments, and long-term economic visions.

South Korea Launches Nationwide Digital Won Pilot
In a significant step toward real-world implementation, the Bank of Korea (BOK) has moved its central bank digital currency (CBDC) initiative into live testing. On April 1, 2025, the BOK launched "Hangang," a large-scale retail CBDC pilot program involving 100,000 consumers and seven financial institutions.
Participants can convert traditional bank deposits into digital won tokens and use them across more than 4,000 online and physical merchants—including convenience stores and major e-commerce platforms like Hyundai Home Shopping. Each transaction is capped at 5 million KRW (approximately $3,700), allowing for meaningful spending while maintaining risk control.
The trial leverages distributed ledger technology (DLT) to enable instant settlement, reducing reliance on legacy clearing systems. A key focus is evaluating smart contracts for public sector applications—such as automated government subsidy disbursements—potentially increasing transparency and efficiency in social spending.
Beyond retail use, the BOK is also advancing wholesale CBDC experiments in collaboration with the Bank for International Settlements (BIS). These efforts explore cross-border securities settlement using tokenized assets, aiming to modernize international capital markets. Notably, one prototype successfully integrates carbon credit trading with payment execution via programmable smart contracts—demonstrating how digital currencies could support sustainable finance goals.
Europe Pushes Back Against Dollar-Dominated Digital Payments
The European Central Bank (ECB) has intensified its drive toward launching a digital euro, framing it as a strategic imperative for preserving monetary sovereignty. In a recent speech, ECB Chief Economist Philip Lane warned that the dominance of U.S.-based payment providers threatens Europe’s financial autonomy.
According to the ECB’s 2024 Payment Markets Report:
- Visa and Mastercard process 65% of all credit card transactions in the eurozone.
- Digital wallets like Apple Pay and Google Pay are accepted by 42% of online merchants.
- Nearly 99% of stablecoin volume is tied to the U.S. dollar.
Lane emphasized that this structural imbalance risks “de facto dollarization” of European digital payments—an outcome that could undermine the effectiveness of EU monetary policy and expose the region to external financial shocks.
To counter this trend, the ECB aims to complete evaluation of its digital euro prototype by October 2025. The proposed design includes critical features such as:
- Offline transaction capability for resilience during connectivity outages
- Pseudonymity to protect user privacy while enabling regulatory oversight
- Holding limits to prevent large-scale displacement of bank deposits
These measures aim to strike a balance between innovation, security, and systemic stability—ensuring the digital euro complements rather than disrupts existing financial infrastructure.

Switzerland Pioneers Hybrid Models for Wholesale Digital Franc
Switzerland continues to lead in exploring advanced models for institutional digital currency. The Swiss National Bank (SNB) recently released findings from its ongoing research into synthetic central bank digital currency (sCBDC)—a hybrid model where private entities issue tokenized money fully backed by central bank reserves.
Unlike traditional retail CBDCs issued directly by central banks, sCBDC allows regulated financial intermediaries to create digital money using central bank collateral. This approach preserves the role of commercial banks while enhancing payment efficiency through tokenization.
The SNB stresses that any sCBDC solution must operate in harmony with existing payment systems and undergo rigorous testing alongside its wholesale CBDC pilot programs. Key evaluation criteria include:
- Interoperability with legacy infrastructure
- Cybersecurity robustness
- Regulatory compliance under anti-money laundering (AML) frameworks
- Operational efficiency in high-value interbank settlements
While no final decision on implementation has been made, the SNB remains committed to prioritizing system safety, transaction speed, and regulatory alignment—principles essential for maintaining Switzerland’s reputation as a global financial hub.
Diverging Paths, Shared Goals: The Global CBDC Landscape
Despite differing technical approaches and use cases, central banks around the world share common motivations behind their digital currency initiatives:
- Monetary Sovereignty: Protecting national control over money issuance amid rising dominance of foreign tech platforms and dollar-linked stablecoins.
- Payment Efficiency: Reducing settlement times, lowering transaction costs, and improving financial inclusion through instant, programmable money.
- Financial Stability: Mitigating risks associated with decentralized private currencies and ensuring central banks retain influence over monetary transmission.
- Innovation Enablement: Leveraging smart contracts and DLT to unlock new capabilities in areas like cross-border trade, fiscal policy delivery, and green finance.
These efforts underscore a broader shift: central banks are no longer passive observers in the digital asset revolution—they are active architects of its next phase.
Frequently Asked Questions (FAQ)
Q: What is a central bank digital currency (CBDC)?
A: A CBDC is a digital form of a country’s official currency issued and backed by its central bank. It functions as legal tender and exists alongside cash and traditional bank deposits.
Q: How does a CBDC differ from cryptocurrency like Bitcoin?
A: Unlike decentralized cryptocurrencies, CBDCs are centrally issued, regulated, and fully backed by government authority. They are not speculative assets but tools for payment and policy implementation.
Q: Can I use a CBDC for everyday purchases today?
A: Most CBDCs are still in pilot stages. While limited trials exist—such as South Korea’s Hangang project—widespread public access is expected only after 2025, pending regulatory approval and system readiness.
Q: Will CBDCs replace cash?
A: No immediate replacement is planned. Central banks emphasize that CBDCs will coexist with physical currency, offering an additional option for digital transactions without eliminating cash.
Q: Are CBDC transactions private?
A: Privacy levels vary by design. Systems like the proposed digital euro will offer pseudonymity—protecting user identity during transactions while allowing authorized oversight for law enforcement purposes.
Q: Could CBDCs help fight climate change?
A: Yes—emerging use cases include embedding environmental conditions into smart contracts. For example, South Korea’s carbon credit integration demonstrates how digital currencies can automate green incentives.
The Road Ahead: Toward Interoperable Digital Money
As central banks refine their digital currency strategies, the focus is shifting from isolated pilots to cross-border interoperability and real-world utility. Collaborative efforts through institutions like the BIS suggest a future where digital currencies seamlessly connect national economies—enabling faster trade settlements, reducing dependency on correspondent banking, and fostering inclusive financial ecosystems.
