AML Screening Software for MAS Compliance: Singapore Need to Know

Singapore’s AML enforcement reached a new level in 2025. MAS fined nine financial institutions $27.45 million following the country’s largest-ever money laundering case, followed by a S$960,000 penalty against five payment institutions for screening failures under MAS Notice PSN01. For compliance teams, these are not distant headlines, but a clear indication of what MAS requires, and where institutions continue to fail.

Understand the requirements of an MAS compliance in 2025, where screening programs will fail, and what an innovative AML solution should have to ensure Singapore-based institutions will be inspection-ready.

The MAS Framework Has Moved — Are Compliance Systems Ready?

The AML/CFT requirements are imposed on MAS by means of a tiered Notice regime. MAS Notice 626 covers banks. Digital payment and token service providers are regulated by notice PSN02, revised on 1 July 2025. Each of the intermediaries of capital markets, financial advisers, trust companies, and payment service providers works under their own Notices.

This was further enriched by the July 2025 reform, which must be assessed at the material stage: Proliferation financing (PF) is now explicitly an official compliance requirement alongside money laundering and terrorism financing. This requirement is in tandem with updated FATF requirements, and it incorporates a compliance layer that lacks PF in most prevailing screening environments.

Under the Financial Services and Markets Act 2022, each Notice 626 has a penalty of up to S$1 million, and S$100,000 per day for the persistence of breaches.

What MAS Found in 2025 Enforcement Review

The nine penalized institutions in MAS’s July 2025 report had control failures that could be identified as:

• Failures in Customer Risk Assessment

The risk rating was not applied in a consistent manner. Risky customers were not identified and reported as expected.

• Verification Lapses in the Source of Wealth

The institutions never put in place proper measures to verify source-of-wealth declarations of high-risk clients. The documentation was accepted without individual validation, which was also present in all nine penalised entities.

• Weaknesses in Transaction Monitoring

Eight institutions out of nine had weak transaction monitoring systems. Alerts were also created, but there was a poor process of reviewing, escalating, and closing.

• Accountability of Senior Management

MAS took direct action against individuals, not just entities. Four employees at Blue Ocean Invest, a licensed fund manager, caught in the $3 billion money laundering case, were put on probation. Formal reprimands were issued to nine other relationship managers. This move of MAS against the people is an indication that the organization is holding individuals liable, not just financial institutions.

What the 2024 National AML Strategy Demands from Technology

In the month of October two years back, Singapore came up with a National AML Strategy. This is a joint initiative taken by the Ministry of Home Affairs, the Ministry of Finance, and the Monetary Authority of Singapore (MAS). The strategy is more focused on three main layers: prevent, detect, and enforce. Each area has direct implications for screening infrastructure.

• Under Prevent, institutions must screen comprehensively before risk materialises, not reactively after a suspicious transaction surfaces.
• Under Detect, revised MAS Notices tighten STR filing timelines: standard suspicious activity must be reported to STRO within five business days. Where a sanctions or proliferation financing link is identified, that deadline drops to one business day.
• Under Enforce, documented case files must be audit-ready at the point of filing. For institutions managing tens of thousands of customers, manually building STR-ready documentation at that pace is not realistic without purpose-built case management.

The Screening Gap Singapore Institutions Cannot Afford

The June 2025 PSN01 enforcement action against five payment institutions identified three specific failures: inadequate customer screening against ML/TF information sources, insufficient identity verification, and incomplete transfer information on cross-border wire transfers.

This exposes a recurring pattern: institutions with policies on paper, but screening tools that cannot execute those policies in practice.

For AML screening software to close that gap in Singapore, it must deliver:

• Real-time, continuous screening against updated global and MAS-relevant watchlists — not overnight batch processing.
• PEP coverage at tier 4 — including relatives, close associates (RCAs), and extended associate networks.
• Multilingual adverse media monitoring — MAS’s 2025 consultation proposed screening in the individual’s native language from relevant jurisdictions.
• Sanctions screening covering primary and secondary exposure — critical for institutions with correspondent banking relationships.
• Crypto and digital asset screening — PSN02 now applies to virtual payment token service providers at the same standard as banks.
• Audit-trail documentation — supporting five-year record retention under MAS requirements.

Why False Positives Are a Challenge that Compliance Teams Can Never Ignore?

High false positive rates are themselves a compliance risk. When analysts are overloaded with non-matches, genuine risk signals get missed.

MAS expects alerts to be properly dispositioned and documented, not just generated. A queued work that has not been properly documented or settled is not a workload issue but rather a control failure.

The COSMIC platform, introduced by MAS in April 2024, is indicative of the direction that the regulatory approach is taking: data-intensive, collaborative, where institutions share red-flag customer data across the financial system. The quality of the alert is more important in that kind of environment than the quantity of alerts that are produced.

Purposely created AML compliance software will contain contextual risk scoring between the name collision and the true match that will minimze the analyst workload and enhance the dependability of what is sent to the human eye.

Not All AML Tools Are Built for Singapore’s Regulatory Moment

There is a real difference between generic compliance software and tools built for the breadth, depth, and pace MAS compliance requires in 2025.  The generic tools are also likely to contain huge lists of sanctions, but not the local MAS data, regional watchlists, or native-language adverse media. They can provide batch processing and not real-time updates. They can produce alerts but not in the context of the scorecard that operationalises the alerts.

Singapore’s enforcement record from 2024 and 2025 is direct since the institutions were not penalised due to any non-compliance; they did not have policies. They were non-conformant because their operational control systems were unable to produce what these policies demanded. The gap should be bridged by anti-money laundering software that Singapore institutions install.

How AML Watcher Helps Close the Gap Between Policy and Practice?

Singapore’s 2025 enforcement record makes one thing clear: the gap MAS is penalising isn’t a knowledge gap; compliance teams know what’s required. It’s an execution gap between what policies demand and what screening systems can actually deliver. Closing that gap is the operational challenge AML Watcher is built to solve. It gives Singapore financial institutions the infrastructure to meet MAS compliance requirements with confidence, real-time sanction and PEP screening across 3,500+ global watchlists, multilingual adverse media monitoring, crypto wallet screening, and audit-grade case management.
