From Rivalry to Synergy: The Convergent Evolution of the Global Digital Currency Ecosystem

With the cooperation of Tether, Turkey's financial regulator successfully froze over $500 million in stablecoin assets suspected of money laundering; simultaneously, Anchorpoint, a joint venture between Standard Chartered Bank, Ancillary Group, and Hong Kong Telecom, formally submitted its application for a stablecoin issuance license to the Hong Kong Monetary Authority. This series of seemingly disparate events actually outlines a clear trajectory of the global digital currency ecosystem moving from initial opposition to deep collaboration. In balancing regulation and innovation, the digital currency world is undergoing a profound evolution from technological experimentation to financial infrastructure.

01 Regulatory Watershed: The Chinese Model and Hong Kong Exploration of the Global Stablecoin Regulatory Framework

Global digital currency regulation is forming a clear geographical divide. In early 2026, the People's Bank of China, the State Administration of Foreign Exchange, and other departments jointly issued the "Notice on Further Preventing and Handling Risks Related to Virtual Currencies," marking the entry of China's regulation of virtual currencies into a stage of institutionalization and normalization. The document explicitly states for the first time: "Without the consent of the People's Bank of China, the State Administration of Foreign Exchange, and other relevant departments in accordance with laws and regulations, no entity or individual, whether domestic or foreign, may issue stablecoins pegged to the RMB overseas." Behind this regulation lies a systemic consideration of monetary sovereignty and financial security.

Stablecoins, through blockchain technology, bypass traditional cross-border capital flow regulatory systems, potentially becoming new channels for capital flight, money laundering, and terrorist financing. The Bank for International Settlements (BIS), in its 2025 research report, "Regulatory Challenges of Stablecoins," points out that the global daily trading volume of stablecoins has surged from $10 billion in 2020 to over $50 billion in 2025, with approximately 30% of transactions involving cross-border flows, posing a potential threat to the exchange rate stability of small, open economies. China's cautious attitude towards RMB-pegged stablecoins is based on the practical need to maintain financial stability.

In contrast to the mainland's prudent regulation, the Hong Kong Special Administrative Region has showcased innovative explorations through a "regulatory sandbox." In August 2025, Anchorpoint Financial Limited, a joint venture between Standard Chartered Bank, Anchor Group, and Hong Kong Telecom, formally submitted an application to the Hong Kong Monetary Authority (HKMA) for a stablecoin issuance license. The HKMA, in its "2025 Fintech Development Roadmap," explicitly stated its intention to promote Hong Kong as an Asian digital asset hub, while ensuring manageable risks. As of January 2026, over 20 financial institutions had expressed their intention to issue stablecoins in Hong Kong, with eight having entered the substantive application stage.

This differentiated regulatory practice under the "One Country, Two Systems" framework provides an important institutional experiment model for the world: it maintains the legal status of sovereign currencies while preserving experimental space for financial innovation.

02 Sovereign Credit Extension: The Integration of the Digital Yuan into the Financial System from Cash to Deposits

The evolution of the digital yuan shows that the true value of central bank digital currencies (CBDCs) lies not only in technological innovation but also in the deep integration with the financial system. On January 1, 2026, the interest calculation mechanism for the digital yuan will be officially implemented, marking its transformation from "digital cash" (M0) to "digital deposits" (M1), completing a qualitative leap towards a mature financial instrument.

The core of this transformation lies in the fundamental adjustment of its measurement framework and financial attributes. According to the "Fourth Quarter Monetary Policy Implementation Report of 2025" released by the People's Bank of China, the balance of commercial banks' digital yuan wallets will be officially included in the deposit reserve base, and participating institutions will be required to pay users interest at the current deposit rate of 0.05%. This means that the digital yuan is no longer a simple cash substitute, but possesses a complete credit creation function.

This upgrade brings multiple impacts. First, banks can build an integrated deposit, loan, and remittance business model based on the digital yuan, solving the problem of a lack of commercial drivers in previous promotions. The head of the Digital Currency Research Institute of the Industrial and Commercial Bank of China pointed out: "The introduction of the interest calculation mechanism allows the digital yuan to seamlessly integrate with the bank's existing business system. It is expected that by the end of 2026, loan products based on the digital yuan will account for more than 5% of our bank's consumer credit business."

Second, this change improves the efficiency of monetary policy transmission. In its January 2026 technical report, "CBDC and Monetary Policy," the International Monetary Fund (IMF) analyzed that interest-bearing CBDCs allow central banks more direct policy tools in a zero-interest-rate environment, particularly during economic downturns, where adjusting CBDC interest rates can directly influence household savings behavior. The launch of Digital Yuan 2.0 is a Chinese practice of this theory.

03 Smart Contract Empowerment: Digital Yuan from Payment Tool to Governance Infrastructure

True technological breakthroughs often lie in their ability to solve social pain points. On February 6, 2026, under the guidance of the People's Bank of China, the first nationwide digital yuan smart contract for migrant worker wage payments was launched in Chengdu, demonstrating the new possibilities of CBDC beyond payments.

This innovation relies on the smart contract ecosystem service platform of the Digital Yuan Operation and Management Center, achieving "contract digitization, automated execution, and transparent supervision." In the migrant worker wage scenario, the general contractor loads a smart payment contract with the opening bank, locking funds for specific purposes. Funds can only be fully paid to workers' digital wallets according to the filed wage details, completely eliminating long-standing problems such as arrears and misappropriation.

Data from the Chengdu Municipal Housing and Construction Bureau shows that in the first month of the pilot program, 120 million yuan in wages were paid to migrant workers through this model, benefiting over 8,000 construction workers. The on-time wage payment rate increased from 78% to 100%. More importantly, the programmability of smart contracts enables automatic matching of fund flows and information flows, significantly reducing regulatory costs.

According to the Digital Currency Research Institute of the People's Bank of China, as of the end of January 2026, digital RMB smart contracts have been piloted in 12 areas, including prepayment fund management, supply chain finance, and government subsidy disbursement, with a cumulative total of 486,400 signed contracts and a transaction amount of 316 million yuan. An expert from the Institute of Finance and Banking of the Chinese Academy of Social Sciences commented: "Smart contracts upgrade the digital RMB from a transaction medium to a rule executor, which may be the most important institutional innovation of CBDC—it embeds compliance requirements through technological means, realizing 'regulation as a service.'"

04 Cross-border Payment Revolution: Multilateral Central Bank Digital Currency Bridges Reconstruct the Global Financial Network

The pain points of traditional cross-border payments—low efficiency, high costs, and poor transparency—are being systematically addressed by the Multilateral Central Bank Digital Currency Bridge (mBridge) project. This project, involving the Bank for International Settlements (BIS) Innovation Centre, the People's Bank of China, and the Hong Kong Monetary Authority, aims to build a new generation of cross-border payment infrastructure centered on CBDC (Central Bank of China).

The practical application of this technology by the Jiangsu Branch of the Bank of China demonstrates its effectiveness. Recently, the bank facilitated a RMB 550 million cross-border payment for a foreign trade company in Nantong through the mBridge, a process that took only 8 seconds and cost less than one-tenth of the cost of traditional SWIFT channels. In contrast, according to the World Bank's 2025 Global Remittances Report, traditional cross-border payments take an average of 3-5 business days, with average costs reaching 6.2% of the remittance amount.

The technological breakthrough of mBridge lies in its "corridor network" design. The BIS's Interim Report on the Money Bridge Project, released in October 2025, points out that the platform achieves interconnectivity with participating central bank CBDC systems, supports peer-to-peer payments, and avoids layers of intermediary bank fees. By the end of 2025, the project had connected the central banks of China, Thailand, the UAE, Hong Kong, and Macau, processing 4,868 cross-border payments totaling RMB 477.8 billion.

More noteworthy is its institutional innovation. The currency bridge employs a "regulatory node" design, allowing regulatory agencies in various countries to monitor cross-border capital flows in real time, ensuring compliance while improving efficiency. This model has gained increasing recognition from central banks. As of January 2026, 12 central banks from Europe, Southeast Asia, and the Middle East had joined the project as observers, indicating that multilateral CBDC cooperation may become the mainstream paradigm for future cross-border payments.

05 Public-Private Collaboration: The Dual-Track Evolution of the Global Financial System Embracing Digital Currency

International financial giants are pragmatically embracing digital currencies, forming a pattern of coexistence, competition, and complementarity between central bank digital currencies (CBDCs) and private stablecoins. Japanese financial giant SBI Holdings, in partnership with Startale Group, plans to launch a yen stablecoin in the second quarter of 2026; previously, the company announced a partnership with Ripple to introduce a dollar stablecoin to the Japanese market.

SBI Holdings Chairman Yoshitaka Kitao's statement is quite representative: "The transition to a 'token economy' has become an irreversible social trend. Our goal is not to replace traditional finance, but to enhance its effectiveness through digital tools." This positioning reflects the evolutionary logic of private stablecoins—no longer attempting to challenge fiat currencies, but rather serving as an enhancement layer to the existing financial system.

The compliance process for stablecoins is equally significant. According to Chainalysis's "2025 Cryptocurrency Compliance Report," by the end of 2025, Tether and Circle, the two major stablecoin issuers, had cooperated with global law enforcement agencies to freeze over $2.5 billion in assets suspected of illegal activities, involving approximately 5,700 wallet addresses. Notably, Tether proactively froze $380 million in USDT related to Southeast Asian fraud groups in the fourth quarter of 2025, demonstrating the regulatory cooperation capabilities of private stablecoins within a compliant framework.

This public-private partnership is reshaping the global digital currency ecosystem. At the 2026 Davos Forum, IMF Managing Director Kristalina Georgieva stated, "The future monetary system will be hybrid—central banks will provide an anchor of trust, while the private sector will provide the impetus for innovation. The key is to ensure the security and fairness of the system through regulation."

06 Conclusion: A New Ecosystem of Integrated and Symbiotic Digital Currency

Shanghai Metro fully supports digital RMB payments, with daily transaction volume exceeding 3 million; migrant workers in Chengdu receive their wages on time via smart contracts; Anchorpoint in Hong Kong awaits approval for its stablecoin license; Tokyo's SBI prepares for the issuance of a yen-denominated stablecoin—these scenarios collectively depict the diverse landscape of the global digital currency ecosystem.

The development of digital currency has transcended the initial narrative of "disrupting traditional finance" and entered a new stage of deep integration with the existing system and solving practical problems.** The digital RMB, through its interest-bearing mechanism and smart contracts, is transforming from a technological product into financial infrastructure; private stablecoins, under clear regulation, have found their place as a supplementary tool for cross-border payments and a testing ground for financial innovation; multilateral cooperation projects such as the Currency Bridge demonstrate new possibilities for global financial governance.

Mu Changchun, Director of the Digital Currency Research Institute of the People's Bank of China, recently wrote that "digital currency is not an end in itself, but a means. The ultimate goal is to build a more efficient, inclusive, and secure financial system." Under this goal, the central bank and the private sector, sovereign currencies and stablecoins, domestic applications and cross-border cooperation are moving from opposition to collaboration, jointly shaping the future form of currency.

The core logic of this transformation is gradually becoming clear: technology empowers finance, finance serves the economy, and regulation safeguards innovation. Maintaining institutional flexibility while upholding the bottom line of financial security, and ensuring controllable risks while encouraging technological innovation, may be the key to the maturation of digital currency from concept to reality. The future is here; it does not belong to any single technological route, but to ecosystems that can find balance in diversity and safeguard value through innovation.
