The Monetary Authority of Singapore concluded its enforcement actions against institutions with nexus to a major money laundering case, imposing penalties ranging from S$1 million to S$5.8 million.

Overview of Penalties

On 4 July 2025, the Monetary Authority of Singapore (MAS) announced composition penalties totalling S$27.45 million against nine financial institutions for breaches of MAS’ Anti-Money Laundering and Countering the Financing of Terrorism (AML/CFT) requirements in relation to the major money laundering case of August 2023. The penalties ranged from S$1.0 million for LGT Bank (Singapore) Ltd. to S$5.8 million for Credit Suisse Singapore Branch, reflecting the culmination of supervisory examinations that began following the landmark case.

These regulatory actions represent the final chapter of MAS’ enforcement against institutions with material nexus to persons of interest (POIs) in the August 2023 money laundering scandal—a case that involved assets exceeding S$3 billion and prompted a sector-wide review of AML controls in Singapore’s financial centre. The penalties took into account three key factors: the extent of each financial institution’s exposure to the POIs, the number of breaches of MAS’ requirements, and the degree of weakness in the institution’s AML/CFT controls.

Breakdown by Institution Type

The sanctioned institutions span three categories of financial licence types, underscoring the breadth of entities that came into contact with the 2023 money laundering network.

Banks bore the largest aggregate penalties, accounting for six of the nine institutions fined. Credit Suisse Singapore Branch received the highest single penalty of S$5.8 million, followed closely by United Overseas Bank at S$5.6 million. UBS AG, Singapore Branch was fined S$3.0 million. Citibank N.A. Singapore and Citibank Singapore Limited—collectively referred to as Citi—were penalised S$2.6 million. Bank Julius Baer & Co. Ltd., Singapore Branch received a S$2.4 million penalty, and LGT Bank (Singapore) Ltd. faced the smallest bank penalty at S$1.0 million.

Capital Markets Services (CMS) licence holders constituted two of the fined entities. UOB Kay Hian Private Limited, one of Singapore's largest stockbroking firms, was penalised S$2.85 million. Blue Ocean Invest Pte. Ltd., a CMS licence holder, received a S$2.4 million penalty—an amount equal to the fine imposed on Bank Julius Baer.

Licensed trust companies were represented by Trident Trust Company (Singapore) Pte. Limited, which was fined S$1.8 million. The inclusion of a trust company in the enforcement actions signals that MAS scrutinised not only traditional banking channels but also trust and corporate service providers that may have been used to obscure beneficial ownership structures linked to the POIs.

Conclusion of the Major ML Case Enforcement

MAS stated that the present suite of actions "marks the conclusion of MAS’ enforcement actions against FIs with material nexus to the major ML case." The regulator confirmed it had completed its supervisory examinations against pertinent financial institutions and their employees who fell short of MAS' AML/CFT requirements.

The penalties, while substantial, reflect a calibrated approach. Regulators emphasised that each composition penalty was determined based on the extent of the FI's exposure to persons of interest, the number of breaches of MAS requirements, and the degree of weakness in the FI's AML/CFT controls. This structured framework provides industry participants with a clear signal that MAS evaluates not merely whether breaches occurred but also the systemic nature of compliance failures and the depth of institutional exposure to illicit actors.

The August 2023 money laundering case—one of the largest in Singapore's history—involved ten foreigners convicted of laundering proceeds from organised crime activities including illegal gambling and fraud. The case exposed vulnerabilities in Singapore's financial system, prompting MAS to conduct extensive examinations of financial institutions that had transacted with the POIs. These examinations identified deficiencies ranging from inadequate customer due diligence and transaction monitoring failures to weaknesses in suspicious transaction reporting protocols.

Outlook. As global regulators intensify AML scrutiny—with enforcement actions in 2024 reaching into the billions of dollars for institutions such as TD Bank in the United States—Singapore's decisive enforcement sets a clear precedent. The S$27.45 million in penalties remind financial institutions that robust compliance programs are non-negotiable in the post-2023 era. Industry participants should expect continued regulatory attention on correspondent banking, trade finance, and cross-border payment channels—areas highlighted by the Wolfsberg Group as high-risk. For financial institutions operating in Singapore, the message is unambiguous: AML/CFT compliance is not a cost centre but a regulatory imperative with real consequences for failures.
