Fintech as Strategic Infrastructure: Hong Kong’s Role in China’s Financial Strategy
Executive Summary
Hong Kong has positioned itself as an international fintech hub in recent years, establishing digital asset licensing regimes, launching sandboxes for emerging technologies, and channelling public resources into Web3 and blockchain development. While the authorities frame these initiatives as efforts to preserve the city’s competitiveness as a global financial centre, this report argues that Hong Kong’s fintech development has become offshore infrastructure for China’s financial security strategy. It is helping Beijing build alternative payment, settlement, digital asset, and offshore RMB systems that extend Chinese influence abroad while reducing reliance on a global financial order still anchored in Western institutions and U.S. dollar dominance.
Although Hong Kong remains a leading hub for international capital flows, it can no longer be treated as a neutral financial centre. With Beijing's deepening political control over the city, Hong Kong's regulatory logic, supervisory practices, and information environment now answer to Beijing's strategic priorities. The consequences extend beyond international businesses operating through the city to the wider system of cross-border financial oversight and enforcement.
Key Findings
Hong Kong’s fintech sector has become Beijing’s offshore laboratory for building an alternative to the Western-led financial order. Today, fintech is no longer simply a collection of digital financial services but an emerging infrastructure of the financial system itself. It encompasses blockchain-based networks, stablecoins, central bank digital currencies (CBDCs), and cross-border settlement systems that underpin how financial transactions are executed, settled, and monitored. Chinese policymakers view these technologies as a generational opportunity to remake the terms on which China engages with global finance. Yet Beijing faces structural constraints in projecting its domestic financial system onto the global stage. Capital controls, restricted RMB convertibility, and tight regulation of digital assets all limit China’s ability to develop more open and internationally oriented financial infrastructure onshore. Hong Kong therefore provides a critical offshore platform, combining a globally respected legal system, established financial architecture, and access to international markets, all under Chinese sovereignty. It allows Beijing to test new forms of digital financial infrastructure, including stablecoin arrangements and mBridge, in a globally connected environment where comparable experimentation remains tightly constrained onshore. At the same time, Hong Kong’s offshore RMB market, Cross-Border Interbank Payment System (CIPS)-linked settlement, and cross-border market-access channels help internationalise Chinese financial infrastructure while deepening Hong Kong’s integration with the mainland financial system.
Hong Kong’s financial infrastructure and regulatory environment increasingly serve China’s strategic interests, creating political risks for international businesses and external regulators. As Beijing has tightened political control over the city, Hong Kong’s regulatory environment has increasingly mirrored China’s political stance and strategic interests. This is visible in the authorities’ rejection of Western-led sanctions as “unilateral”, in the city’s continued role in supporting Chinese companies linked to sensitive technologies or military activities, and in its facilitation of transactions linked to Russia, Iran and other partners. Such transactions often resemble established patterns of illicit financial flows and money laundering under international regulatory frameworks, including the use of front companies, multi-jurisdictional transaction layering, and offshore accounts, with digital assets increasingly incorporated as an additional channel for cross-border value transfer. While Hong Kong maintains a comprehensive anti-money laundering (AML) and countering the financing of terrorism (CFT) framework, regulators face political pressure in classifying or enforcing against activities that involve Chinese interests or sanctions Beijing rejects. This opens a widening gap between international regulatory expectations and local enforcement practice. The divergence is reinforced by China’s anti-sanctions framework, which exerts political and legal pressure on Hong Kong’s regulatory authorities not to implement foreign sanctions deemed contrary to Chinese interests.
Hong Kong has tightened information control in response to international scrutiny, masking the city’s deepening role in China’s financial strategy. As international scrutiny grows over Hong Kong’s role in facilitating transactions involving sanctioned Chinese entities and China’s strategic partners, the authorities have sought to protect the city’s global reputation. However, rather than restricting such activities, they have moved to shape international perceptions through increasing information control, limiting how the activities become visible and scrutinised. This is reflected in tighter control over media reporting, constraints on due diligence and corporate intelligence, and changes in regulatory disclosure in areas such as sanctions monitoring, China-related listing risks, and specialist technology initial public offerings (IPOs). The combined effect is to make it harder for businesses, investors, and external regulators to independently verify exposure to China-linked financial risks. Although Hong Kong authorities point to renewed IPO activity and business confidence as evidence that the city’s business environment remains intact, these market signals do not fully capture the deeper political and regulatory realignment under way beneath them.
Hong Kong’s financial infrastructure creates new geopolitical risk exposure for international businesses, with that exposure deepening as operational integration grows. As cross-border finance grows more dependent on integrated digital platforms, firms operating through the city are increasingly embedded in settlement, custody, liquidity, data, and compliance systems that are costly to unwind. Connect programmes already link international investors to China’s capital markets through Hong Kong’s settlement and custodial framework, while CIPS-linked settlement and cross-border data arrangements deepen this operational dependence. As Hong Kong’s financial infrastructure aligns more closely with Beijing’s strategic interests, that dependence brings direct political exposure during geopolitical crises, ranging from asset freezes and settlement disruption to liquidity restrictions and retaliatory measures. Russia’s 2022 invasion of Ukraine demonstrated how rapidly exposure to a geopolitically adversarial jurisdiction can become costly and difficult to unwind, with major Western energy firms facing large write-downs, delayed exits, and in several cases expropriation before orderly withdrawal was possible. In Hong Kong, these risks are compounded by constraints on the information environment and by divergent regulatory and data governance regimes, making it harder for firms to assess exposure, detect early warning signals, and comply across jurisdictions.
Recommendations
International governments should:
Incorporate financial infrastructure dependence into existing risk and exposure disclosures. Financial regulators should require banks, asset managers, and institutional investors to disclose dependence on Hong Kong’s settlement, custody, data, and alternative-payment infrastructure, including CIPS, mBridge, Central Bank Digital Currency (CBDC) platforms, and stablecoin arrangements, as a distinct risk category alongside geographic exposure and concentration risk.
Close the sanctions and AML/CFT enforcement gap created by China’s alternative payment systems. In coordination with allies through the G7 and the Financial Action Task Force (FATF), treasury departments, financial intelligence units, and financial regulators should monitor CIPS, CBDC platforms, and digital asset settlement systems, impose enhanced due-diligence and reporting requirements on participating institutions, and update sanctions and AML/CFT frameworks to close the enforcement gaps these systems create.
Embed Hong Kong financial coercion scenarios in China contingency planning. Defence, treasury, and foreign ministries should jointly model scenarios in which Beijing uses Hong Kong’s settlement systems, custodial architecture, and cross-border data platforms as instruments of strategic leverage, including in a Taiwan contingency, and develop pre-positioned response options including financial countermeasures and rapid relocation pathways for moving critical operations out of Hong Kong.
Establish supported relocation pathways for firms exiting Hong Kong. Financial regulators in alternative financial centres, including the UK, EU member states, Singapore, and Japan, should establish fast-track approval processes for international firms relocating or duplicating critical operations away from Hong Kong, with published timelines and streamlined regulatory pathways. Central banks should ensure that such firms can rapidly access payment, settlement, and liquidity systems.
International businesses should:
Conduct a board-level audit of dependency and exposure to Hong Kong’s financial infrastructure. Senior leadership should assess the full extent of operational integration with Hong Kong’s settlement, custody, data, liquidity, and compliance infrastructure, quantify potential losses, asset freezes, and operational inaccessibility under severe disruption, and treat the exercise as risk assessment rather than compliance review.
Stress-test for simultaneous Western sanctions and Beijing countermeasures. Firms should develop scenario exercises simulating Western-led sanctions on Chinese and Hong Kong financial entities alongside Beijing’s retaliatory measures, including potential application of the Anti-Foreign Sanctions Law, identify points at which automated compliance systems may receive conflicting instructions, and ensure clear human decision-making authority is in place to resolve them.
Build pre-positioned diversification pathways out of Hong Kong. Firms should identify critical financial operations currently routed through Hong Kong that could be relocated or duplicated in jurisdictions such as Singapore, Tokyo, or London, and begin pre-positioning legal entities, regulatory authorisations, and operational infrastructure capable of activation on short notice.
Minimise sensitive-data exposure within Hong Kong’s data infrastructure. Businesses should limit processing and storage of sensitive financial and commercial data within Hong Kong to what is operationally necessary, segment data systems to handle high-value information outside jurisdictions with divergent governance regimes, and account for the accelerating integration of Hong Kong’s data infrastructure with China’s centrally governed architecture.
