In July, 2025 Monetary Authority of Singapore (MAS) levied a total of S27.45 million (US21.5 million) in fines against 9 financial institutions that categorically violated anti-money laundering (AML) regulatory laws. This was the second-largest regulatory fine in the history of the city-state that followed only those associated with the 1MDB scandal.It followed a far-reaching investigation into a massive laundering scheme connected to S$3 billion in illicit assets.
The implementation will be an inflexion point in the regulatory environment of Singapore. Singapore is facing a new battle over more fundamental weaknesses in financial oversight that has long been seen as a symbol of financial soundness and cleanliness. The web of unethical activities of the high-profile Chinese citizens, vast digital networks, and the structural failure of complaints is not only a revelation of loopholes but rather a question of credibility of the city in the international arena.
Dissecting the laundering operation
The Fujian network and the S$3 billion case
The primary focus of the investigation was a transnational criminal enterprise often referred to as the Fujian syndicate. This network was used to launder billings of illegal proceeds of online gambling and other illegal sources into the Singapore banking system, trust companies and property markets.
Law enforcement acquired or confiscated S$2.79 billion of luxury homes, money, precious metals, expensive vehicles, and paintings by late 2024. Ten Chinese nationals were found guilty, and some others are still under investigation to testify how the legal endeavour is known to transpire on.
Institutional involvement and penalties imposed
The nine institutions fined by MAS include major domestic and international banks. The largest penalty was S$5.8 million on Credit Suisse Singapore (by now a division at UBS) and S$5.6 million penalty on UOB. The other banks, which were fined, are UBS Singapore, Citibank N.A. Singapore, Citibank Singapore, Julius Baer, and LGT Bank.
These institutions were seen to be in violation of some of their crucial AML requirements such as adequate risk-assessment, due-diligence and enquiry of suspicious transactions. Most Often, internal policies existed, though they were applied arbitrarily or done merely in form.
MAS’s enforcement strategy and its limitations
Targeting both banks and fintechs
MAS made it clear that its enforcement sweep extended beyond conventional banks. In June 2025, five payment service providers were fined a total of S$960,000 for AML violations under the Payment Services Act. This simultaneous focus on digital financial platforms reflects the regulator’s growing awareness of how fintech channels have expanded the risks of illicit money flows.
Such measures underscore MAS’s intent to send a message across the entire financial ecosystem: lapses, whether legacy or emerging, will face consequences.
Inconsistencies between policy and execution
MAS’s inspections revealed that while AML frameworks existed on paper, institutions struggled with implementation. Five banks failed to conduct proper customer risk assessments. Eight failed to investigate flagged transactions. And all nine failed to verify the origins of wealth for high-risk clients.
This is a wide-spread failure that indicates that compliance operations must have been deprioritized toward taking on high-value clients especially offering high-value short term returns. It also points out that automation and checklists are no replacements of human scrutiny in compliance.
Institutional responses and structural challenges
Public commitments to reform
Most of the fined institutions responded promptly and publicly. UBS confirmed its cooperation and promised tighter controls. UOB stated it had enhanced its transaction monitoring systems. Citibank and Julius Baer both emphasized their commitment to better governance and AML compliance.
However, these declarations raise a familiar dilemma. Similar commitments were made after the 1MDB case. And yet, within a few years, a bigger, more decentralized scheme went undetected by some of the same actors. The cycle points to an underlying resistance to proactive compliance investment—particularly when such investment appears to threaten profitability.
Enforcement alone isn’t enough
The regulators of the past and financial professionals have been cautioning that financial institutions tend to view fines as a cost of operation. Executives can only become accountable personally or have their licenses threatened, otherwise change is a systemic measure.
MAS has made efforts to make sure that there is monitoring that follows even after the imposing of the fines, although the question that needs to be asked is whether this monitoring bears fruit at the institutional level.
Risks to Singapore’s financial identity
Global scrutiny and reputation management
Singapore’s rise as a global financial hub has rested on a foundation of transparency, regulatory certainty, and rule of law. That reputation is now under pressure. The fact that such a vast laundering network operated in plain sight, facilitated by multiple licensed banks, invites uncomfortable comparisons with jurisdictions known for “light-touch” regulation.
Critics argue that Singapore’s financial institutions have historically relied on the assumption that MAS’s strict image would shield them from deeper scrutiny. This scandal tests that assumption.
Balancing innovation with compliance
Singapore has embraced financial innovation aggressively, supporting digital banking licenses, blockchain initiatives, and payment system modernization. But innovation without regulatory guardrails increases exposure. The inclusion of payment service providers in the 2025 fines is a signal that MAS understands this dual-edged sword.
The key going forward will be aligning compliance oversight with technological change—ensuring that fintechs and neobanks are held to the same standards as traditional players.
Structural reforms and the way forward
Compliance culture and technological solutions
The future of AML enforcement will depend heavily on technological augmentation. AI-driven transaction monitoring, real-time risk scoring, and blockchain forensics are all tools that can detect suspicious patterns faster than conventional compliance teams.
However, these tools can never prove effective when not enfolded in a culture. The financial institutions have to motivate the compliance officers, increase their leverage in the strategic decisions and make sure that further questioning of high-value transactions is not a punishable act but a much-wanted culture.
Institutional accountability and incentives
There is a growing call for MAS to explore frameworks that hold senior executives personally liable for repeated compliance failures. Without such measures, penalties—even large ones—may not alter the risk calculus at the top levels of management.
Moreover, compliance should not be siloed within legal or audit departments. It must be integrated into product development, client acquisition, and performance metrics—especially in a city where financial services are deeply interwoven with the broader economy.
Expert insights and public discourse
K. Shaughnessy has spoken on the topic in an interview, offering a sharp critique of Singapore’s current approach. Shaughnessy emphasized that while the fines were necessary,

What this signals for global banking norms
Singapore’s handling of the Fujian syndicate scandal is now under global observation. For financial hubs competing for international trust—London, Zurich, Hong Kong—the message is clear: regulators can no longer rely on reputation alone. They must demonstrate enforcement, transparency, and a willingness to adapt.
For Singapore, the test is not just whether it recovers from this scandal, but whether it rebuilds in a way that sets a new benchmark for global compliance. Will boards act before regulators step in? Will banks invest in prevention rather than mitigation? The answers could define not just the future of Singapore’s finance sector—but the global norms for AML oversight in a digital economy.
