The Enforcement Action: Nine Firms, S$27.45 Million in Penalties
The Monetary Authority of Singapore (MAS) announced on 4 July 2025 that it had completed regulatory actions against nine financial institutions, imposing total composition penalties of S$27.45 million for breaches of Anti-Money Laundering and Countering the Financing of Terrorism (AML/CFT) requirements. The actions concluded MAS’s supervisory examinations of financial institutions with nexus to persons of interest (POIs) in the August 2023 money laundering case, which involved more than S$3 billion in assets. Penalties were determined based on the extent of each institution’s exposure to POIs, the number of breaches of MAS requirements, and the degree of weakness in AML/CFT controls, as stated in the MAS’s 4 July 2025 media release.
The enforcement action represents one of the largest coordinated AML penalty exercises by MAS, targeting a mix of six global and regional banks, two capital market services licence holders, and one licensed trust company. MAS emphasised that the penalties factored in the severity and systemic nature of the compliance failures identified during its supervisory examinations, which began after the 2023 scandal broke.
Breakdown of Financial Penalties by Institution
The composition penalties imposed on each institution, as detailed in MAS’s 4 July 2025 announcement, are as follows:
Credit Suisse Singapore Branch: S$5.8 million
United Overseas Bank Limited (UOB): S$5.6 million
UBS AG, Singapore Branch: S$3.0 million
UOB Kay Hian Private Limited: S$2.85 million
Citibank N.A. Singapore and Citibank Singapore Limited (collectively Citi): S$2.6 million
Bank Julius Baer & Co. Ltd., Singapore Branch: S$2.4 million
Blue Ocean Invest Pte. Ltd.: S$2.4 million
Trident Trust Company (Singapore) Pte. Limited: S$1.8 million
LGT Bank (Singapore) Ltd.: S$1.0 million

Composition Penalties Imposed by MAS on Nine Financial Institutions (S$ million)
The two largest penalties—S$5.8 million and S$5.6 million—were levied against Credit Suisse Singapore Branch and UOB respectively, reflecting the highest exposure to the persons of interest in the 2023 case and the most severe control weaknesses identified.
Nature of Breaches and Individual Accountability
MAS identified common shortcomings across the nine institutions. According to the regulator’s findings, the institutions demonstrated failures in customer risk assessments, inability to adequately trace sources of customers’ wealth, and insufficient monitoring of transactions flagged as suspicious. AML/CFT policies, where they existed, were inconsistently implemented across business lines and client portfolios.
Beyond institutional penalties, MAS issued prohibition orders and reprimands against 18 executives and managers for their roles in the compliance failures. Prohibition orders, lasting between three and six years, were issued to four former or current executives at Blue Ocean Invest Pte. Ltd., according to regulatory filings. The affected individuals included senior management and compliance officers who had failed to develop, update, and audit effective AML/CFT policies, conduct sufficient customer due diligence, and escalate or investigate red flags associated with high-risk clients.
In a related but separate enforcement action, on 27 June 2025, MAS penalised five Major Payment Institutions (MPIs) a total of S$960,000 for AML/CFT breaches. Those penalties, which preceded the 4 July announcements, stemmed from inadequate customer screening against money laundering and terrorism financing information sources, insufficient customer identity verification, and incomplete transfer information for cross-border wire transfers. The MPIs are licensed to provide cross-border money transfer services, a sector that has drawn increasing regulatory attention given its role in the 2023 scandal.
The enforcement actions are grounded in Singapore’s AML/CFT regulatory framework, which operates under MAS Notices issued pursuant to the Monetary Authority of Singapore Act (MAS Act 1970) and the Financial Services and Markets Act 2022 (FSMA). Each breach of these notices constitutes an offence under section 27B(2) of the MAS Act and/or section 16(4) of the FSMA, with statutory penalties reaching up to S$1,000,000 per offence. The compounded fines imposed are authorised under section 176(1A) of the MAS Act and section 177(1) of the FSMA.
MAS’s actions align with the three aims of its enforcement approach, as stated in its latest Enforcement Report: early detection of misconduct and breaches of laws, effective deterrence, and shaping business and market conduct. The regulator signalled that it will continue to provide AML/CFT guidance to financial institutions and take robust enforcement action, with a focus on cross-border collaboration and digital asset misconduct.
The industry should expect sustained scrutiny. Recent amendments to AML/CFT Notices and Guidelines for financial institutions came into effect on 1 July 2025, following MAS’s April 2025 consultation. These amendments broaden obligations around customer due diligence, transaction monitoring, and suspicious transaction reporting. For compliance officers and senior management across Singapore’s financial sector, the message from MAS is unambiguous: the two-year examination cycle may have concluded, but the enforcement architecture is now more demanding than ever.
