Hong Kong’s New Financial Crime Info-Sharing Law: A Turning Point for Asia’s Fight Against Fraud and Money Laundering

A quiet legislative milestone in Hong Kong this month may prove to be one of the most transformative anti-financial crime initiatives in Asia-Pacific in years.

On June 4, Hong Kong’s Legislative Council passed the Banking (Amendment) Bill 2025, a forward-thinking law designed to enhance the detection and prevention of financial crime through regulated, secure information-sharing between banks and law enforcement agencies.

At a time when financial fraud and cyber-enabled money laundering are rising sharply across the region, this legislative development marks a shift in how governments and financial institutions collaborate in the face of sophisticated criminal threats. It also positions

Hong Kong as a regulatory innovator—offering lessons for other markets in Asia grappling with similar challenges.

What the New Law Enables

At its core, the new law creates a legal and technological infrastructure that allows banks to share personal and corporate account information with one another—and with law enforcement—when financial crime is suspected.

Under strict conditions, banks will now be able to use designated digital channels such as the Financial INtelligence Evaluation Sharing Tool (FINEST) to exchange data relating to:

• Suspected money laundering

• Terrorist financing

• Proliferation financing

• Fraud and associated illegal activity

  
  

While post-suspicion sharing is prioritized in the first phase, future mechanisms are planned to enable pre-suspicion data collaboration, which could enhance proactive detection and intervention.

Why This Is a Game Changer for Asia-Pacific

Financial crime is no longer limited by borders or traditional tools. Fraudsters leverage technology, shell entities, and digital assets to hide identities and move funds quickly across jurisdictions. This makes timely intelligence sharing between banks not just beneficial—but essential.

Hong Kong’s law addresses several longstanding challenges in the region:

1. Breaking Down Data Silos in Banking

Historically, banks in Asia-Pacific have operated in silos, even when suspecting the same individuals or entities of fraud. With limited legal grounds and mechanisms for peer-to-peer sharing, many institutions are left to fight well-organized financial crime networks in isolation.

By formalizing and protecting information flows, the new law empowers banks to move faster, detect sooner, and intervene earlier—without fear of violating privacy rules.

2. Strengthening Regional AML Capabilities

As a leading international finance hub, Hong Kong’s actions set an important precedent. Other financial centers such as Singapore, Tokyo, and Sydney may soon consider similar frameworks to keep pace with evolving criminal typologies, including:

• Cross-border fraud rings

• Cyber-enabled mule accounts

• Layering through multiple institutions

With Asia-Pacific increasingly under pressure from global watchdogs to enhance AML/CFT enforcement, Hong Kong’s approach shows a balance between data protection, operational efficiency, and cross-sector collaboration.

3. Aligning with FATF and Global Best Practices

The Financial Action Task Force (FATF) has long encouraged public-private partnerships and secure intelligence exchange as key components of national AML strategies. Hong Kong’s new law aligns with these global standards and reinforces its credibility as a responsible, proactive jurisdiction.

Technology at the Core: FINEST and Secure Digital Exchange

The foundation of the new law’s operational model is FINEST, a digital platform launched by the HKMA in 2023 that allows secure communication between financial institutions.

This kind of infrastructure is critical. Without a reliable, encrypted, and auditable channel, information-sharing efforts often stall. FINEST serves as:

• A data pipeline for post-suspicion alerts

• A compliance-protected mechanism to reduce manual back-and-forth

• A potential future hub for real-time, multi-bank transaction monitoring

As financial institutions across Asia continue modernizing their core systems, integrating with such platforms will become a cornerstone of fraud prevention architecture.

Implications for Financial Institutions in Hong Kong and Beyond

For banks, the law opens up new possibilities—but also new responsibilities. Institutions must now:

• Update internal protocols to reflect data sharing rules

• Upgrade systems to interface with secure HKMA platforms

• Train compliance teams to handle outbound and inbound information within legal boundaries

• Establish governance around what constitutes “suspected conduct” and when to escalate

Meanwhile, fintechs and cross-border digital lenders operating in or through Hong Kong will need to understand how this law may impact KYC, onboarding, and transaction monitoring obligations—especially if future extensions include digital wallet providers or non-bank players.

What the Rest of Asia Should Watch For

As fraud levels rise in markets like Thailand, Malaysia, Indonesia, and Vietnam, regional regulators may increasingly view Hong Kong’s model as a benchmark.

Instead of solely emphasizing enforcement after the fact, Hong Kong is moving toward real-time, intelligence-led disruption—a strategy that could significantly reduce losses and improve the effectiveness of anti-money laundering systems.

Countries with similar ambitions may explore:

• National data-sharing frameworks between banks

• Secure platforms modeled on FINEST

• Legal reforms to protect institutions that act in good faith

• Pre-suspicion intelligence-sharing for early intervention

Conclusion: From Compliance to Collaboration

Hong Kong’s new financial crime info-sharing law is more than a policy update—it’s a paradigm shift. By unlocking secure, regulated data collaboration across institutions, the city is setting a new standard for proactive financial crime prevention in Asia-Pacific.

For financial institutions, regulators, and compliance leaders across the region, the message is clear: fraud and financial crime are no longer challenges to be tackled alone. Collaboration, supported by clear laws and smart technology, is the way forward.

As this law takes effect, it will not only safeguard Hong Kong’s financial system but may also inspire a broader regional movement toward smarter, faster, and more connected financial crime response strategies.
