AML Red Flags in Fund Subscriptions and Redemptions
Money moves into a fund at subscription and out at redemption, so that is where laundering shows. This guide sets out the red flags regulators name, why each one matters, what to do when one appears, and a worked example for fund managers, administrators and transfer agents.
Fund managers often treat AML as an onboarding task. The subscription is checked, the investor is approved, and the file is closed. But a fund can be used to launder money only if money moves through it, and most of that movement happens at two points: when the investor pays in and when the fund pays out. FATF Recommendation 10(d) requires scrutiny of transactions throughout the relationship to ensure they are consistent with what the firm knows about the customer, their business and risk profile, and, where necessary, the source of funds.
This article is for compliance, operations and investor-relations teams at fund managers, fund administrators and transfer agents. It draws on the indicator lists published by the Monetary Authority of Singapore (MAS) and the Securities and Futures Commission of Hong Kong (SFC), with US references where they apply. It cites the texts as read on 7 November 2026 and is general information, not legal advice. For the reporting process itself, see our guide to SAR and STR filing.
Why Fund Dealing Is Where Laundering Shows
A fund offers a launderer three things: a regulated counterparty, an investment story that explains large sums, and a redemption payment that looks like legitimate investment proceeds. The SFC puts the risk plainly in its chapter on third-party payments: when a customer uses a third party to pay for or receive the proceeds of an investment, the arrangement may be used to disguise the true beneficial owner or the source of funds (Guideline 11.1).
Fund terms change the risk. In its final investment adviser AML rule, FinCEN said an adviser assessing a private fund may wish to consider minimum subscription amounts, restrictions on the type of investors, restrictions on redemptions or withdrawals, and the types of currency transactions conducted with investors. It also said funds with redemption restrictions cannot be treated as categorically lower risk, because other factors about the fund and its investors matter too (89 FR 72191). That rule's effective date has been delayed to 1 January 2028 (91 FR 36), but the risk analysis is a useful guide for any fund.
Responsibility is shared but not transferred. The fund or its manager usually remains responsible for its AML obligations even where an administrator or transfer agent performs the checks, as our article on fund administrator AML responsibilities explains. Red flags therefore need a route from whoever sees the payment to whoever decides on a report.
Red Flags at Subscription
These are the indicators to watch when an investor applies and pays in. Each is drawn from the MAS Guidelines to Notice SFA04-N02 (Appendix B, "Examples of Suspicious Transactions") or the SFC AML/CFT Guideline (Appendix B, "Illustrative indicators of suspicious transactions and activities", and Chapter 11).
| Red flag at subscription | Why it matters (our analysis unless cited) | Where the regulator says so |
|---|---|---|
| Source of funds unclear, or out of line with the investor's profile and apparent standing | The fund may be the first place criminal proceeds enter the regulated system | MAS Guidelines App. B, B-2(vii) and B-6(vii); SFC Guideline App. B, 1(g) |
| Payment from someone other than the investor, such as a company, relative or unrelated person | A third-party payer can disguise the true beneficial owner or the source of funds | SFC Guideline 11.1 and 11.3; MAS App. B, B-4(iv) and B-4(ix) |
| Cash or cash-like funding for an investment | Cash breaks the audit trail. MAS's guide to a large cash amount is one exceeding S$20,000 or its equivalent | MAS App. B, B-3(ii) and B-3(vii); SFC App. B, 5(a) |
| Reluctance to give normal information, or information that is minimal, false, misleading or hard to verify | Missing CDD is itself a reason to consider an STR | MAS App. B, B-1-4; MAS Notice 13.3; SFC App. B, 1(h) |
| The application is withdrawn once CDD questions start | An investor who walks away when asked for evidence may be testing the controls | MAS Notice 13.3(b) |
| Unnecessary complexity: offshore companies, trusts or bearer shares with no clear reason | Layers make the beneficial owner harder to identify | SFC App. B, 1(c), 1(d) and 2(a); MAS App. B, B-4(vi) |
| Several accounts or subscriptions with the same beneficial owners and no business reason | Splitting can keep each holding below review triggers. MAS separately flags many accounts with frequent transfers between them | SFC App. B, 1(e) and 5(h); compare MAS App. B, B-2(ii) |
| Unusual interest in your AML controls or reporting thresholds, or no interest at all in fees and costs | Behaviour that suggests the investor is planning around the controls, not the investment | SFC App. B, 1(j) and 1(k) |
| An intermediary not subject to adequate AML/CFT rules submits the subscription | You may be relying on checks that were never done | MAS App. B, B-8(viii) |
| Links to higher-risk countries with no explanation that fits the investor | Geography is a standard risk factor; for countries subject to an FATF call for countermeasures, MAS requires the relationship to be treated as higher risk | MAS Notice 8.6(a); SFC App. B, 5(f) |
Two of these deserve emphasis for funds. First, a third-party payment should be the exception: the SFC says third-party deposits or payments should be accepted only in exceptional and legitimate circumstances that are reasonably in line with the customer's profile and normal commercial practices (11.3), and its due diligence process includes critically evaluating the reasons for the arrangement, taking reasonable measures on a risk-sensitive basis to verify the third party's identity and ascertain its relationship to the customer, approval by a designated approver (a senior manager with an AML/CFT role, or the MLRO), and documenting the findings (11.5). Second, if you already have reasonable grounds to suspect before the relationship starts, Singapore requires you not to establish it and to file an STR (Notice 6.2). Our article on source of funds and source of wealth covers the evidence to ask for.
Red Flags at Redemption and During the Holding
Once the investor is in, the signs change. Most of these involve the way money leaves the fund, or an investor whose dealing no longer matches the profile you recorded at onboarding.
| Red flag at redemption or during the holding | Why it matters (our analysis unless cited) | Where the regulator says so |
|---|---|---|
| Redemption soon after subscription, with no plausible reason, sometimes accepting a fee or a loss | The fund is used to turn dirty money into a clean-looking payment from a regulated entity | MAS App. B, B-2(iii) (footnote 22 covers funds deposited for fund management purposes); SFC App. B, 1(i) and 1(k) |
| Proceeds to a third party, or to an account in a different name from the investor | Layering: value moves to someone whose link to the investor is unknown | SFC Guideline 11.1, 11.5 and footnote 103; SFC App. B, 5(e) |
| Frequent changes of bank details for receiving proceeds, or of address or authorised signatories | Also a common sign of account takeover fraud | SFC App. B, 5(k); MAS App. B, B-8(iv) |
| Proceeds sent to another jurisdiction from the one the money came from | Cross-border hops make funds harder to trace | SFC App. B, 5(j) and 5(c) |
| The holding works as a conduit: money in and out with little real investment | The account behaves like a deposit account, not an investment | SFC App. B, 5(b); MAS App. B, B-5(iii) |
| Transfers of units or interests between parties with no apparent relationship | A transfer can move value without cash passing through the fund's accounts | SFC App. B, 2(c) and 5(d) |
| Activity out of line with the investor's profile: size, frequency or a sudden change of pattern | The core test of ongoing monitoring | FATF Rec 10(d); MAS App. B, B-8(i); SFC App. B, 2(b) |
| Structured or staggered dealing that appears designed to stay under thresholds | In the US, a transaction designed to evade BSA requirements through structuring is itself a SAR trigger for mutual funds (31 CFR 1024.320(a)(2)(ii)) | SFC App. B, 5(h); MAS Guidelines 6-10-7(b); 31 CFR 1024.320 |
Early redemption deserves a word of caution. Investors redeem early for many legitimate reasons, including a change in circumstances, a better opportunity elsewhere, or concerns about the fund. MAS frames the indicator as withdrawal immediately after deposit "unless the customer's business activities furnish a plausible reason" (B-2(iii)). In our view, the red flag is the combination: a short holding, indifference to cost, and a payee who is not the investor.
Payments to third parties are rarer still. The SFC notes that the need for third-party payments "should be rare" and that the circumstances that justify them may differ from those for third-party deposits (footnote 103). For structuring patterns, see our article on smurfing and structuring.
How the Red Flags Differ by Fund Type
The indicator lists are written for capital markets firms in general. How they show up depends on the fund's dealing terms. The table below is our own mapping, not a regulator's.
| Fund type | Where the pressure points are | What to watch (our view) |
|---|---|---|
| Open-ended funds (daily, weekly or monthly dealing) | Money can go in and come out quickly | Round trips; redemptions to new accounts; investors who accept dealing costs without question |
| Closed-ended private funds (private equity, private credit, real estate) | Capital calls, distributions and secondary transfers rather than redemptions | Capital calls paid by someone other than the LP; distributions to a changed account; transfers of interests to parties you have not onboarded |
| Funds sold through intermediaries | The fund may see a nominee or platform, not the end investor | Whether the intermediary is regulated and supervised for AML/CFT; unusual flows from one intermediary account |
For closed-ended funds, capital calls and distributions are the subscription and redemption equivalents, so the same tests apply: who paid, from where, and who receives the proceeds. Our LP onboarding checklist covers the onboarding side, including bank account details.
What to Do When a Red Flag Appears
A red flag is a reason to look, not a conclusion. MAS says the list of examples is intended as an aid and "must not be applied as a routine instrument in place of common sense" (Guidelines B-1-1). The steps below follow the MAS and SFC texts.
Stop and look before you act
Do not process the payment or the redemption on autopilot. The SFC says that where a transaction is not consistent with what the firm knows about the customer, or is unusual, the firm should take steps to examine it further (Guideline 7.3, read with 5.13 to 5.20). In our view, a short hold while you ask questions is usually better than processing and investigating later.
Ask questions, carefully
Ask the investor for an explanation and evidence: why the payment came from a third party, why proceeds should go to a new account. The SFC says enquiries made properly and in good faith do not constitute tipping-off (5.16). MAS says a customer's explanations should be checked for plausibility and not accepted without scrutiny (Guidelines B-1-3).
Know when to stop the CDD
If you have formed a suspicion and reasonably believe that continuing CDD would tip off the investor, MAS allows you to stop, provided you document the basis for that assessment and file an STR (Notice 13.4). The SFC takes the same approach where you reasonably believe CDD would tip off the customer (5.16).
Escalate to one point
MAS requires a single reference point to whom all employees, officers and representatives must promptly refer suspected transactions, and records of all transactions referred to STRO with the internal findings and analysis (Notice 13.1). The Guidelines add that the basis for not filing on escalated cases should be documented (13-6). In practice the reference point is usually the MLRO, as the SFC expects (7.9). Make sure your administrator and transfer agent know who that is and how quickly they must escalate.
Decide on reporting and record the reasons
If suspicion remains, report it. Singapore requires STRs to STRO promptly, regardless of the amount (Notice 13.2), and MAS expects filing within 5 business days after the firm concludes an STR is warranted (save in exceptional circumstances), and as soon as possible and no later than 1 business day for cases involving sanctioned parties or those acting for them (Guidelines 13-1). Hong Kong requires a report to the JFIU as soon as it is reasonable once a person knows or suspects (Guideline 7.1). In the US, a mutual fund must file a SAR for suspicious transactions of at least $5,000, generally within 30 calendar days of initial detection (31 CFR 1024.320). Record the decision either way: the SFC expects findings and rationale to be documented in writing (5.17).
Re-rate the investor and keep watching
Update the investor's risk rating, decide whether enhanced monitoring is needed, and decide whether to continue the relationship. Keep any report confidential from the investor: tipping-off is an offence in Hong Kong (SFC Guideline 7.6), the MAS Notice directs Singapore firms to the tipping-off provision in section 57 of the CDSA (Notice footnotes 4 and 12), and US SAR confidentiality rules apply to mutual funds (1024.320(d)).
Reporting Rules at a Glance
| Regime | Who you report to | Timing and threshold | Source |
|---|---|---|---|
| FATF standard | The financial intelligence unit (FIU) | Report promptly if you suspect, or have reasonable grounds to suspect, that funds are criminal proceeds or related to terrorist financing | FATF Recommendation 20 |
| Singapore (capital markets intermediaries, including fund managers) | Suspicious Transaction Reporting Office (STRO) | Promptly, including attempted transactions, regardless of amount; copy to MAS on request. MAS expects filing within 5 business days after the firm concludes an STR is warranted, save in exceptional circumstances (1 business day for cases involving sanctioned parties) | MAS Notice SFA04-N02, 13.2; Guidelines 13-1 |
| Hong Kong (SFC-licensed corporations) | Joint Financial Intelligence Unit (JFIU) | As soon as it is reasonable once a person knows or suspects; no minimum amount. Failure to report carries a maximum penalty of three months' imprisonment and a fine of HK$50,000 | SFC Guideline 7.1, 7.5 and footnote 90 |
| United States (mutual funds) | FinCEN, on Form SAR | Transactions of at least $5,000; no later than 30 calendar days after initial detection, extendable to 60 days if no suspect is identified | 31 CFR 1024.320 |
| United States (investment advisers) | FinCEN | The IA AML Rule, including SAR filing, has had its effective date delayed to 1 January 2028; FinCEN said it will use the delay to review and, as applicable, tailor the rule | 89 FR 72156; 91 FR 36 |

Worked Example: The Three-Week Round Trip
Illustrative scenario. An open-ended fund with monthly dealing receives a USD 2 million subscription in the name of an individual investor. The money arrives from a company account held at a bank in a third country. Three weeks later the investor asks to redeem in full at the next dealing day, accepts the early-redemption charge, and asks for the proceeds to go to a bank account in the name of a different company, held in another jurisdiction.
- Red flags. A third-party payer at subscription (SFC 11.1); a redemption after a very short holding period with no reasonable explanation (SFC App. B, 1(i); compare MAS B-2(iii)); indifference to cost (SFC 1(k)); proceeds to an unrelated third party in another jurisdiction (SFC 11.1 and App. B, 5(j)).
- What the operations team does. It flags the redemption instead of processing it, and refers it to the MLRO the same day.
- What compliance does. It reviews the onboarding file, asks the investor how the paying company and the receiving company relate to them, and requests evidence. The answers do not reconcile: the investor cannot show a link to the receiving company.
- Outcome. The MLRO decides that suspicion has been formed, files an STR with the relevant FIU, documents the reasons, and takes legal advice on how to deal with the pending redemption without tipping off the investor. The investor is re-rated as high risk.
- Lesson. Each flag alone might have had an innocent explanation. Together they did not. MAS makes the same point: one situation may not be enough, but a combination may indicate a suspicious transaction (Guidelines B-1-1).
Controls Checklist for Fund Managers and Administrators
Use this list to test whether your controls would catch the red flags above. Each item links to a regulator text where one exists; the rest are our recommendations.
- A written policy on third-party payments in both directions, approved by senior management, setting out when they may be accepted and who approves them. The SFC says third-party deposits or payments should be accepted only in exceptional and legitimate circumstances (11.3).
- Investors asked to designate bank accounts in their own name for subscriptions and redemptions. The SFC strongly encourages firms to require clients to designate accounts in their own names, or those of acceptable third parties, for deposits, and notes that designated accounts of acceptable third parties for withdrawals make it easier to check a third-party payee before paying (11.4 and footnote 107).
- Monitoring parameters written down, independently validated and reviewed periodically. MAS expects this of the parameters and thresholds used to identify suspicious transactions (Guidelines 6-10-12).
- Monitoring that looks across all of an investor's holdings and related accounts, not one fund at a time (MAS Guidelines 6-10-10 and 6-10-11).
- Screening repeated when the investor's connected parties or beneficial owners change, as well as periodically (MAS Notice 6.40).
- Clear escalation from the administrator or transfer agent to the fund's MLRO, with time limits, in the administration agreement.
- Staff training that uses these red flags with your own fund terms: dealing frequency, lock-ups, redemption charges and transfer rules.

Frequently Asked Questions
What are the most common AML red flags in fund redemptions?
Redemption soon after subscription with no plausible reason, especially where the investor accepts a fee or a loss; proceeds paid to a third party or to an account in a different name; frequent changes of bank details for receiving proceeds; and proceeds sent to a different jurisdiction from the one the money came from. These appear in the SFC Guideline Appendix B and the MAS Guidelines to Notice SFA04-N02 Appendix B.
Is an early redemption suspicious in itself?
No. Investors redeem early for many legitimate reasons. MAS frames the indicator as assets withdrawn immediately after being deposited, unless the customer's business activities furnish a plausible reason. Look at the combination: how long the money was invested, whether the investor cared about the cost, who receives the proceeds and whether the explanation is plausible.
Can a fund accept a subscription paid by a third party?
It depends on the regime and the fund's policy. The SFC says third-party deposits or payments should be accepted only in exceptional and legitimate circumstances that fit the customer's profile and normal commercial practices, after taking reasonable, risk-sensitive measures to verify the third party's identity and ascertain its relationship to the customer, with approval from a designated approver such as a senior manager or the MLRO, and documenting the findings. Many funds simply require payment from an account in the investor's own name.
Does asking the investor about a red flag count as tipping off?
Not if it is done properly. The SFC says enquiries made properly and in good faith do not constitute tipping-off. But if you reasonably believe that continuing CDD would tip off the investor (in Singapore, once you have formed a suspicion), MAS and the SFC allow you to stop, document why, and file an STR. Never tell an investor that a report has been or may be made.
Is there a minimum amount for reporting a suspicious fund transaction?
Not in Singapore or Hong Kong: MAS Notice SFA04-N02 requires STRs regardless of the amount, and the Hong Kong reporting duty applies irrespective of the amount involved. US mutual funds must file a SAR for suspicious transactions involving at least $5,000, but may report smaller amounts voluntarily.
Who should spot red flags: the manager or the administrator?
Both, in practice. The administrator or transfer agent usually sees the payments first, while the manager or fund remains responsible for its AML obligations in most regimes. The administration agreement should say who monitors what, how quickly red flags are escalated, and who decides whether to report.
