Correspondent banking is a crucial aspect of the global financial system, allowing banks to provide services to their clients across borders. It involves one bank, known as the correspondent, offering various banking-related services to an overseas bank, referred to as the respondent.

This arrangement facilitates international trade, enables efficient cross-border payments, and fosters economic growth. However, correspondent banking relationships have also been exploited for illicit purposes, particularly money laundering. Due to the cross-border nature of these transactions and the sometimes weak regulations surrounding them, criminals have taken advantage of correspondent banking to hide the origins of their illicit funds.

Correspondent banking plays a crucial role in facilitating cross-border financial transactions, but it is not immune to vulnerabilities. The global nature of correspondent banking relationships has made it an attractive avenue for money launderers to disguise the origins of their illicit funds. The weak regulations surrounding these transactions have provided criminals with the perfect opportunity to exploit the system. This has led to a number of notable cases where correspondent banking relationships have been used for money laundering purposes.

In the following infographic, we delve into some notable cases where correspondent banking relationships were exploited for financial crime.

While correspondent banking plays a crucial role in facilitating cross-border transactions and promoting economic growth, it has become an attractive avenue for criminals to conceal the origins of their illicit funds. In response to this challenge, banks and regulatory authorities must take proactive measures to strengthen their due diligence processes and enhance their monitoring capabilities. By doing so, they can effectively detect and prevent money laundering activities, thus safeguarding the integrity of the correspondent banking system. This is vital to ensure that correspondent banking continues to fulfil its essential role in facilitating international trade and driving economic prosperity.

AML Risk Assessment: A Practical Framework for Banks and Fintechs in Asia

Risk assessment is the foundation of every AML compliance programme. Regulators across APAC are explicit about it: the controls an institution puts in place — its monitoring thresholds, its CDD tiers, its STR workflows — must be derived from a documented assessment of that institution's specific money laundering and financing of terrorism risks. A generic risk assessment produced for an examiner and then filed away is not just insufficient. It is the root cause of most examination failures.

This guide covers what an AML risk assessment must contain, the four risk dimensions every institution must evaluate, how MAS, AUSTRAC, BNM and BSP approach risk assessment requirements, and the common failures that examiners consistently find.

Talk to an Expert

Why the Risk-Based Approach Requires a Documented Risk Assessment

FATF Recommendation 1 establishes the risk-based approach as the cornerstone of global AML/CFT frameworks: countries and institutions should identify, assess and understand their ML/FT risks, and apply measures proportionate to those risks. This is not a suggestion — every APAC regulatory framework has embedded this requirement into binding law and supervisory guidance.

The practical implication is that no two institutions should have identical AML programmes. A Singapore digital bank serving retail PayNow users faces different risks from a Malaysian trade finance institution handling cross-border commodity transactions. An institution that deploys vendor-default monitoring rules without anchoring them to a documented risk assessment cannot demonstrate to supervisors that its controls are proportionate to its risks.

The risk assessment is also a living document. Regulators across APAC require institutions to review and update it whenever material changes occur — new products, new customer segments, new delivery channels, acquisitions, or changes in the external risk environment (new FATF grey list additions, updated national risk assessments).

The Four Risk Dimensions

A complete AML risk assessment covers four categories of inherent risk:

1. Customer Risk

Customer risk is typically the most significant driver of an institution's overall ML/FT risk profile. Key factors to assess:

  • Customer type: Retail vs. corporate vs. institutional. Within corporate, assess ownership structure complexity, industry sector, and beneficial ownership transparency.
  • PEP exposure: What proportion of the customer base are Politically Exposed Persons or their family members and close associates? High PEP concentration requires more extensive EDD capacity.
  • Non-resident and cross-border customers: Customers based outside the institution's jurisdiction, or who conduct significant cross-border activity, represent elevated risk due to reduced visibility into source of funds.
  • High-risk sectors: Customers operating in cash-intensive businesses (retail, hospitality, gaming), real estate, precious metals and stones, or legal and accounting services carry higher inherent risk.

2. Product and Service Risk

Each product an institution offers carries its own ML/FT risk profile based on how easily it can be used to move, layer or integrate illicit funds:

  • Payment services: Real-time payment rails (PayNow, NPP, InstaPay, DuitNow) with pre-settlement processing create exposure to rapid fund movement and mule network activity.
  • Cash-accepting products: ATMs, cash deposit facilities, and cash-settled products require specific controls for structuring and threshold monitoring.
  • Digital asset services: Crypto exchange, custody, and settlement services require typology coverage for mixing patterns, rapid conversion, and cross-chain transfers.
  • Trade finance: Documentary credits, bills of lading, and commodity financing are among the highest-risk products for trade-based money laundering (TBML).
  • Private banking and wealth management: Complex investment structures, trust arrangements, and high-value low-frequency transactions require enhanced monitoring capabilities.

3. Geographic Risk

Geographic risk covers both where customers are located and where transactions are directed:

  • FATF grey list and black list jurisdictions: Transactions to or from FATF-listed countries require enhanced scrutiny. As of 2026, active monitoring of the FATF grey list is a regulatory baseline expectation across all APAC jurisdictions.
  • High-risk third countries: Individual country risk ratings from MAS, AUSTRAC, BNM and BSP guidance — some countries carry elevated risk even without formal FATF designation.
  • Domestic geographic risk: Within-country risk concentration. In the Philippines, certain provinces have higher exposure to specific predicate offences. In Malaysia, specific industries in specific regions may carry elevated risk.
  • Correspondent banking corridors: For institutions with correspondent banking relationships, the risk profile of respondent institution jurisdictions must be assessed.

4. Delivery Channel Risk

How customers access products and services affects the institution's ability to verify identity, detect suspicious behaviour, and monitor transactions:

  • Non-face-to-face onboarding: Digital onboarding through apps, online portals, or third-party introducers carries higher initial CDD risk than face-to-face identification. Most APAC regulators allow digital onboarding subject to specific verification controls (e.g., MyInfo in Singapore, eKYC under BNM guidance in Malaysia).
  • Third-party reliance: Where institutions rely on introducers or third parties for CDD, the risk that controls were not properly applied transfers to the institution.
  • Agent networks: For payment companies using agent networks for cash-in/cash-out, each agent represents a CDD and transaction monitoring control point.

How APAC Regulators Require Risk Assessments

MAS (Singapore)

MAS Notice 626 requires banks to document their ML/FT risk assessments and use them as the basis for their AML/CFT frameworks. MAS's risk-based supervisory approach means that examination intensity is directly calibrated to the assessed risk profile of the institution. The 2024 Singapore National Risk Assessment identified trade finance, cross-border private banking, and digital payment channels as elevated risk areas — institutions with material exposure to these areas are expected to reflect them prominently in their risk assessments.

AUSTRAC (Australia)

Under the AML/CTF Rules Part 2, Australian reporting entities must conduct a money laundering and terrorism financing (ML/TF) risk assessment covering their customers, the ML/TF risk of each designated service they provide, delivery channels, and the countries they deal with. The risk assessment must be documented, kept up to date, and made available to AUSTRAC on request. The Tranche 2 reforms extending obligations to lawyers, accountants and real estate agents (effective from 2026 under the AML/CTF Amendment Act 2024) have elevated the importance of sector-specific risk assessment methodology.

BNM (Malaysia)

Bank Negara Malaysia's AML/CFT/CPF/TFS Policy Document (2023) requires reporting institutions to conduct an enterprise-wide risk assessment (EWRA) covering the full scope of their ML/TF/PF/TFS risks. The EWRA must be reviewed at least annually and whenever material changes occur. BNM's supervisory focus in 2025–2026 has emphasised the quality of risk assessment documentation — specifically whether identified risks are actually driving control design — following findings of disconnect between risk assessments and monitoring configurations across multiple examination cycles.

BSP (Philippines)

BSP Circular 706 mandates a risk-based approach across all covered persons. Risk assessments must identify ML/FT/PF risks inherent to the institution's business model and must be used to calibrate CDD levels, monitoring thresholds, and reporting obligations. BSP's examination programme has focused increasingly on NBFI and e-money issuer risk assessments following the Philippines' 2023 FATF grey list exit, with examiners checking whether post-exit risk profiles have been updated to reflect the changed supervisory environment.

Translating Risk Assessment Outputs Into Controls

A risk assessment that does not drive control design is a compliance document, not a risk management tool. The direct outputs should include:

CDD tiering: Customer segments assessed as higher risk must be mapped to EDD requirements. The risk assessment should specify which customer types trigger EDD, what additional information must be collected, and who must approve the relationship. For PEP screening guidance tied to the customer risk component of the assessment, see our PEP Screening Guide.

Monitoring scenario design: Each high-risk area identified in the assessment should map to at least one detection scenario in the transaction monitoring system. If the risk assessment identifies trade-based money laundering as a material risk but the monitoring system has no TBML-specific rules, the programme has a control gap that examiners will find.

Reporting thresholds: STR determination criteria and CTR thresholds should reflect the assessed risk profile. Institutions with high-risk customer segments should not be applying the same STR escalation criteria as a low-risk institutional counterparty book.

Resource allocation: Higher-risk products, channels and customer segments require more investigation capacity. The risk assessment should inform staffing levels and case management workflow design.

For a practical evaluation framework for transaction monitoring systems that can support risk-based monitoring at scale, see our Transaction Monitoring Software Buyer's Guide.

Common Risk Assessment Failures in APAC Examinations

Supervisors across MAS, AUSTRAC, BNM and BSP have identified recurring risk assessment deficiencies:

Boilerplate risk assessments. Documents that describe general industry risks rather than the institution's specific risk profile. An e-money issuer in the Philippines and a trade finance bank in Singapore should not have risk assessments that look similar. Generic risk assessments fail the first examiner question: "How is this assessment specific to your business?"

Risk assessment not driving monitoring design. The most common finding across all jurisdictions — the risk assessment identifies high-risk customer segments or products, but the monitoring system runs vendor-default rules that do not target those specific risks. The control gap between the documented risk and the deployed detection scenario is the core failure.

Static assessments not updated for material changes. Institutions that launched digital banking products, expanded into new markets, or onboarded new customer segments without updating their risk assessment are out of compliance with the update obligation in every APAC jurisdiction.

Residual risk not assessed. The risk assessment identifies inherent risk but does not assess the adequacy of existing controls in reducing that risk to an acceptable residual level. Supervisors expect to see both the inherent risk score and the institution's assessment of whether current controls are sufficient.

No board sign-off or inadequate governance trail. The risk assessment must be approved by senior management and the board in most jurisdictions. A risk assessment that exists as a compliance team document without board-level ownership does not satisfy governance requirements.

Building a Risk Assessment That Drives Your Programme

A defensible AML risk assessment for an APAC financial institution requires:

  • Institution-specific risk identification across all four dimensions — customer, product, geography, channel
  • Quantified risk scoring (high/medium/low) with documented rationale for each rating
  • Assessment of existing controls against identified risks, producing a residual risk view
  • Direct mapping of risk outputs to monitoring scenarios, CDD tiers, and reporting thresholds
  • Annual review cycle with interim updates triggered by material changes
  • Board approval and documented governance trail
  • Alignment with the current national risk assessment for each operating jurisdiction

Institutions evaluating whether their current compliance infrastructure can support a genuinely risk-based programme — including transaction monitoring systems that can be calibrated to specific risk outputs rather than running vendor defaults — should start with the monitoring layer. See our Transaction Monitoring Software Buyer's Guide for an evaluation framework built around risk-based requirements.

Best AML Software for Singapore: What MAS-Regulated Institutions Need to Evaluate

“Best” isn’t about brand—it’s about fit, foresight, and future readiness.

When compliance teams search for the “best AML software,” they often face a sea of comparisons and vendor rankings. But in reality, what defines the best tool for one institution may fall short for another. In Singapore’s dynamic financial ecosystem, the definition of “best” is evolving.

This blog explores what truly makes AML software best-in-class—not by comparing products, but by unpacking the real-world needs, risks, and expectations shaping compliance today.

Talk to an Expert

The New AML Challenge: Scale, Speed, and Sophistication

Singapore’s status as a global financial hub brings increasing complexity:

  • More digital payments
  • More cross-border flows
  • More fintech integration
  • More complex money laundering typologies

Regulators like MAS are raising the bar on detection effectiveness, timeliness of reporting, and technological governance. Meanwhile, fraudsters continue to adapt faster than many internal systems.

In this environment, the best AML software is not the one with the longest feature list—it’s the one that evolves with your institution’s risk.

What “Best” Really Means in AML Software

1. Local Regulatory Fit

AML software must align with MAS regulations—from risk-based assessments to STR formats and AI auditability. A tool not tuned to Singapore’s AML Notices or thematic reviews will create gaps, even if it’s globally recognised.

2. Real-World Scenario Coverage

The best solutions include coverage for real, contextual typologies such as:

  • Shell company misuse
  • Utility-based layering scams
  • Dormant account mule networks
  • Round-tripping via fintech platforms

Bonus points if these scenarios come from a network of shared intelligence.

3. AI You Can Explain

The best AML platforms use AI that’s not just powerful—but also understandable. Compliance teams should be able to explain detection decisions to auditors, regulators, and internal stakeholders.

4. Unified View Across Risk

Modern compliance risk doesn't sit in silos. The best software unifies alerts, customer profiles, transactions, device intelligence, and behavioural risk signals—across both fraud and AML workflows.

5. Automation That Actually Works

From auto-generating STRs to summarising case narratives, top AML tools reduce manual work without sacrificing oversight. Automation should support investigators, not replace them.

6. Speed to Deploy, Speed to Detect

The best tools integrate quickly, scale with your transaction volume, and adapt fast to new typologies. In a live environment like Singapore, detection lag can mean regulatory risk.

Why MAS Compliance Requirements Change the Evaluation

Singapore's AML/CFT framework is more prescriptive than most compliance teams from outside the region expect. MAS Notice 626 sets specific requirements for banks and merchant banks: risk-based transaction monitoring with documented calibration, explainable detection decisions for examination purposes, and typology coverage aligned to Singapore's specific ML threat profile. For a full breakdown of what MAS Notice 626 requires from banks and how those requirements translate to monitoring system specifications, see our MAS Notice 626 guide.

For payment service providers licensed under the Payment Services Act 2019, MAS Notice PSN01 and PSN02 set equivalent CDD, transaction monitoring, and STR filing obligations. Software that meets European or US regulatory requirements may not generate the alert documentation, investigation trails, or STR workflows that MAS examiners look for.

The practical evaluation question is not which vendor ranks highest on global analyst lists — it is which solution can demonstrate, in an MAS examination, that:

  • Alert thresholds are calibrated to your customer risk profile, not vendor defaults
  • Every alert has a documented investigation and disposition decision
  • STR workflow meets the "as soon as practicable" filing obligation
  • Detection scenarios cover Singapore-specific typologies: mule account networks, PayNow pre-settlement fraud, shell company structuring across corporate accounts

The Role of Community and Collaboration

No tool can solve financial crime alone. The best AML platforms today are:

  • Collaborative: Sharing anonymised risk signals across institutions
  • Community-driven: Updated with new scenarios and typologies from peers
  • Connected: Integrated with ecosystems like MAS’ regulatory sandbox or industry groups

This allows banks to move faster on emerging threats like pig-butchering scams, cross-border laundering, or terror finance alerts.

Case in Point: A Smarter Approach to Typology Detection

Imagine your institution receives a surge in transactions through remittance corridors tied to high-risk jurisdictions. A traditional system may miss this if it’s below a certain threshold.

But a scenario-based system—especially one built from real cases—flags:

  • Round dollar amounts at unusual intervals
  • Back-to-back remittances to different names in the same region
  • Senders with low prior activity suddenly transacting at volume

The “best” software is the one that catches this before damage is done.

A Checklist for Singaporean Institutions

If you’re evaluating AML tools, ask:

  • Can this detect known local risks and unknown emerging ones?
  • Does it support real-time and batch monitoring across channels?
  • Can compliance teams tune thresholds without engineering help?
  • Does the vendor offer localised support and regulatory alignment?
  • How well does it integrate with fraud tools, case managers, and reporting systems?

If the answer isn’t a confident “yes” across these areas, it might not be your best choice—no matter its global rating.

For a full evaluation framework covering the criteria that matter most for AML software selection, see our Transaction Monitoring Software Buyer's Guide.

What Singapore Institutions Should Prioritise in Their Evaluation

Tookitaki’s FinCense platform embodies these principles—offering MAS-aligned features, community-driven scenarios, explainable AI, and unified fraud and AML coverage tailored to Asia’s compliance landscape.

There’s no universal best AML software.

But for institutions in Singapore, the best choice will always be one that:

  • Supports your regulators
  • Reflects your risk
  • Grows with your customers
  • Learns from your industry
  • Protects your reputation

Because when it comes to financial crime, it’s not about the software that looks best on paper—it’s about the one that works best in practice.

KYC Requirements in Singapore: MAS CDD Rules for Banks and Payment Companies

Singapore's KYC framework is more specific — and more enforced — than most compliance teams from outside the region expect. The Monetary Authority of Singapore does not publish voluntary guidelines on customer due diligence. It issues Notices: binding legal instruments with criminal penalties for non-compliance. For banks, MAS Notice 626 sets the requirements. For payment service providers licensed under the Payment Services Act, MAS Notice PSN01 and PSN02 apply.

This guide covers what MAS requires for customer identification and verification, the three tiers of CDD Singapore institutions must apply, beneficial ownership obligations, enhanced due diligence triggers, and the recurring gaps MAS examiners find in KYC programmes.

Talk to an Expert

The Regulatory Foundation: MAS Notice 626 and PSN01/PSN02

MAS Notice 626 applies to banks and merchant banks. It sets out prescriptive requirements for:

  • Customer due diligence (CDD) — when to perform it, what it must cover, and how to document it
  • Enhanced due diligence (EDD) — specific triggers and minimum requirements
  • Simplified due diligence (SDD) — the limited circumstances where reduced CDD applies
  • Ongoing monitoring of business relationships
  • Record keeping
  • Suspicious transaction reporting

MAS Notice PSN01 (for standard payment licensees) and MAS Notice PSN02 (for major payment institutions) under the Payment Services Act 2019 set equivalent obligations for payment companies, e-wallets, and remittance operators. The CDD framework in PSN01/PSN02 mirrors the structure of Notice 626 but calibrated to payment service business models — including specific requirements for transaction monitoring on payment flows, cross-border transfers, and digital token services.

Both Notices are regularly updated. Institutions should refer to the current MAS website versions rather than archived copies — amendments following Singapore's 2024 National Risk Assessment update guidance on beneficial ownership verification and higher-risk customer categories.

When CDD Must Be Performed

MAS Notice 626 specifies four triggers requiring CDD to be completed before proceeding:

  1. Establishing a business relationship — KYC must be completed before onboarding any customer into an ongoing relationship
  2. Occasional transactions of SGD 5,000 or more — one-off transactions at or above this threshold require CDD even without an ongoing relationship
  3. Wire transfers of any amount — all wire transfers require CDD, with no minimum threshold
  4. Suspicion of money laundering or terrorism financing — CDD is required regardless of transaction value or customer type when suspicion arises

The inability to complete CDD to the required standard is grounds for declining to onboard a customer or for terminating an existing business relationship. MAS examiners check that institutions apply this requirement in practice, not just in policy.

Three Tiers of CDD in Singapore

Singapore's CDD framework has three levels, applied based on the customer's assessed risk:

Simplified Due Diligence (SDD)

SDD may be applied — with documented justification — for a limited category of lower-risk customers:

  • Singapore government entities and statutory boards
  • Companies listed on the Singapore Exchange (SGX) or other approved exchanges
  • Regulated financial institutions supervised by MAS or equivalent foreign supervisors
  • Certain low-risk products (e.g., basic savings accounts with strict usage limits)

SDD does not mean no due diligence. It means reduced documentation requirements — but institutions must document why SDD applies and maintain that justification in the customer file. MAS does not permit SDD to be applied as a default for corporate customers without case-by-case assessment.

Standard CDD

Standard CDD is the baseline requirement for all other customers. It requires:

  • Customer identification: Full legal name, identification document type and number, date of birth (individuals), place of incorporation (entities)
  • Verification: Identity documents verified against reliable, independent sources — passports, NRIC, ACRA business registration, corporate documentation
  • Beneficial owner identification: For legal entities, identify and verify the natural persons who ultimately own or control the entity (see below for the 25% threshold)
  • Purpose and intended nature of the business relationship documented
  • Ongoing monitoring of the relationship for consistency with the customer's profile

Enhanced Due Diligence (EDD)

EDD applies to higher-risk customers and situations. MAS Notice 626 specifies mandatory EDD triggers:

  • Politically Exposed Persons (PEPs): Foreign PEPs require EDD as a minimum. Domestic PEPs are subject to risk-based assessment. PEP status extends to family members and close associates. Senior management approval is required before establishing or continuing a relationship with a PEP. EDD for PEPs must include source of wealth and source of funds verification — not just identification.
  • Correspondent banking relationships: Respondent institution KYC, assessment of AML/CFT controls, and senior management approval before establishing the relationship
  • High-risk jurisdictions: Customers or transaction counterparties connected to FATF grey-listed or black-listed countries require EDD and additional scrutiny
  • Complex or unusual transactions: Transactions with no apparent economic or legal purpose, or that are inconsistent with the customer's known profile, require EDD investigation before proceeding
  • Cross-border private banking: Non-face-to-face account opening for high-net-worth clients from outside Singapore requires additional verification steps

EDD is not satisfied by collecting more documents. MAS examiners look for evidence that the additional information gathered was actually used in the risk assessment — source of wealth narratives that are vague or unsubstantiated are treated as inadequate EDD, not as EDD completed.

ChatGPT Image May 20, 2026, 11_33_41 AM

Beneficial Owner Verification

Identifying and verifying beneficial owners is one of the most examined areas of Singapore's KYC framework. MAS Notice 626 requires institutions to identify the natural persons who ultimately own or control a legal entity customer.

The threshold is 25% shareholding or voting rights — any natural person who holds, directly or indirectly, 25% or more of a company's shares or voting rights must be identified and verified. Where no natural person holds 25% or more, the institution must identify the natural persons who exercise control through other means — typically senior management.

For layered corporate structures — where ownership runs through multiple holding companies across different jurisdictions — institutions must look through the structure to identify the ultimate beneficial owner. MAS examiners consistently flag beneficial ownership documentation failures as a top finding in corporate customer reviews. Accepting a company registration document without looking through the ownership chain does not satisfy this requirement.

Trusts and other non-corporate legal arrangements require identification of settlors, trustees, and beneficiaries with 25% or greater beneficial interest.

Digital Onboarding and MyInfo

Singapore's national digital identity infrastructure supports MAS-compliant digital onboarding. MyInfo, operated by the Government Technology Agency (GovTech), provides verified personal data — NRIC details, address, employment, and other government-held data — that institutions can retrieve with customer consent.

MAS has confirmed that MyInfo retrieval is acceptable for identity verification purposes, reducing the documentation burden for individual customers. Institutions using MyInfo for onboarding must document the verification method and maintain records of the MyInfo retrieval.

For corporate customers, ACRA's Bizfile registry provides business registration and officer information that can be used for entity verification. Beneficial ownership still requires independent verification — Bizfile shows registered shareholders but does not always reflect ultimate beneficial ownership through nominee structures.

Ongoing Monitoring and Periodic Review

KYC is not a one-time onboarding requirement. MAS Notice 626 requires ongoing monitoring of established business relationships to ensure that transactions remain consistent with the institution's knowledge of the customer.

This has two components:

Transaction monitoring — detecting transactions inconsistent with the customer's business profile, source of funds, or expected transaction patterns. For the transaction monitoring requirements that feed into this ongoing CDD obligation, see our MAS Notice 626 guide.

Periodic CDD review — customer records must be reviewed and updated at intervals appropriate to the customer's risk rating. High-risk customers require more frequent review. The review must check whether the customer's profile has changed, whether beneficial ownership has changed, and whether the risk rating remains appropriate.

The trigger for an out-of-cycle CDD review includes: material changes in transaction patterns, adverse media, connection to a person or entity of concern, and changes in beneficial ownership.

Record-Keeping Requirements

MAS Notice 626 requires institutions to retain CDD records for five years from the end of the business relationship, or five years from the date of the transaction for one-off customers. Records must be maintained in a form that allows reconstruction of individual transactions and can be produced promptly in response to an MAS request or court order.

The five-year clock runs from the end of the relationship — not from when the records were created. For long-term customers, this means maintaining KYC documentation, transaction records, SAR-related records, and correspondence for the full relationship period plus five years.

Suspicious Transaction Reporting

Singapore uses Suspicious Transaction Reports (STRs) filed with the Suspicious Transaction Reporting Office (STRO), administered by the Singapore Police Force. There is no minimum transaction threshold — any transaction, regardless of amount, that raises suspicion must be reported.

STRs must be filed as soon as practicable after suspicion is formed. The Act does not set a specific deadline in days, but MAS examiners and STRO guidance indicate that delays of more than a few business days without documented justification will attract scrutiny.

The tipping-off prohibition under the Corruption, Drug Trafficking and Other Serious Crimes (CDSA) Act makes it a criminal offence to disclose to a customer that an STR has been filed or is under consideration.

For cash transactions of SGD 20,000 or more, institutions must file a Cash Transaction Report (CTR) regardless of suspicion. CTRs are filed with STRO within 15 business days.

Common KYC Failures in MAS Examinations

MAS's examination findings and industry guidance consistently flag the same recurring gaps:

Beneficial ownership not traced to ultimate natural persons. Institutions stop at the first layer of corporate ownership without looking through nominee shareholders or holding company structures to identify the actual controlling individuals.

EDD documentation without substantive assessment. Files contain EDD documents — source of wealth declarations, bank statements, company accounts — but no evidence that the documents were reviewed, assessed, or used to update the risk rating.

PEP definitions applied too narrowly. Institutions identify foreign government ministers as PEPs but miss domestic senior officials, senior executives of state-owned enterprises, and immediate family members of identified PEPs.

Static customer profiles. CDD completed at onboarding is never updated. Customers whose transaction patterns have changed significantly since onboarding retain their original risk rating without periodic review.

MyInfo used as a complete KYC solution. MyInfo satisfies identity verification for individuals but does not substitute for source of funds verification, purpose of relationship documentation, or beneficial ownership checks on corporate structures.

STR delays. Suspicion forms during transaction review but is not escalated or filed for days or weeks. Case management systems without deadline tracking are the most common operational cause.

For Singapore institutions evaluating whether their current KYC and monitoring systems can meet these requirements, see our Transaction Monitoring Software Buyer's Guide for a full framework covering the capabilities MAS-regulated institutions need.
