Money laundering isn’t just a crime drama cliché. It’s a sophisticated, evolving threat that financial institutions must constantly guard against. 

But let’s face it! Criminals are getting smarter.  

They manipulate financial systems, disguise transactions, and exploit loopholes, making it harder than ever to spot wrongdoing. A single overlooked red flag can lead to hefty fines, regulatory crackdowns, and irreparable reputational damage. That’s why Money Laundering Reporting Officers (MLROs) need to stay sharp, recognize the warning signs, and act fast. 

From suspicious transaction patterns to rapid fund movements across multiple accounts, let’s break down the key red flags MLROs can’t afford to miss and MLRO responsibilities—and how to respond effectively. 

The Key Red Flags and MLRO Responsibilities You Should be Aware

1. Unusual Transaction Patterns 

One of the most common indicators of suspicious activity is a transaction pattern that does not align with a customer’s typical behavior or business profile. MLROs should be on high alert for: 

• Sudden spikes in transaction volumes from an account that historically had low activity. 

• Round-number transactions (e.g., exactly $10,000 or $50,000) that may be structured to avoid reporting thresholds. 

• Frequent deposits followed by rapid withdrawals without clear business justification. 

• Splitting large transactions (smurfing) to avoid regulatory scrutiny. 

Case Example: 

A retail business with a declared monthly revenue of $50,000 suddenly starts receiving daily wire transfers of $100,000 from different sources. This discrepancy warrants immediate investigation. 

2. Rapid Movement of Funds 

The speed at which funds move can also signal money laundering or illicit financial flows. Red flags include: 

• Immediate transfers in and out of an account without any apparent reason. 

• Multiple transfers to different accounts before reaching the final beneficiary (a classic layering technique in money laundering). 

• Frequent international transfers, particularly to high-risk jurisdictions identified by the Financial Action Task Force (FATF). 

Case Example: 

An individual deposits $500,000 into their account and, within 24 hours, wires the entire amount to multiple accounts in different countries. This behavior indicates potential layering of illicit funds. 

3. Inconsistent Customer Information 

A key component of AML compliance is Know Your Customer (KYC). If a customer’s financial activity does not align with their declared income, occupation, or business nature, it could be a red flag. Warning signs include: 

• Mismatch between income and transaction volume (e.g., a student account receiving large wire transfers). 

• Frequent changes in account ownership or authorized signatories without a reasonable explanation. 

• Use of multiple accounts under different names but controlled by the same entity. 

Case Example: 

A small consulting firm with minimal declared income starts processing millions of dollars in transactions. This calls for enhanced due diligence. 

4. Transactions Involving High-Risk Countries or Entities 

Certain jurisdictions are known for weak AML enforcement. Transactions linked to these regions should be examined closely. Red flags include: 

• Transfers to or from countries with high money laundering risks (as per FATF grey/blacklists). 

• Payments to shell companies in tax havens with no legitimate business activity. 

• Transactions involving politically exposed persons (PEPs) that could indicate corruption risks. 

Case Example: 

A customer frequently wires large sums to an offshore company registered in a jurisdiction with no AML regulations. Without a clear business purpose, this is a red flag. 

5. Use of Third Parties or Unusual Payment Methods 

Criminals often use intermediaries to obscure the source of illicit funds. MLROs should be wary of: 

• Payments made through unrelated third parties with no apparent connection. 

• Multiple individuals depositing into a single account with no clear reason. 

• Use of cryptocurrency or prepaid cards to bypass banking scrutiny. 

Case Example: 

A real estate purchase is funded by multiple wire transfers from various unrelated individuals. This could indicate an attempt to launder illicit funds. 

6. Attempts to Avoid Compliance Measures 

Some customers deliberately try to bypass AML procedures. MLROs should be alert to: 

• Refusal to provide KYC documents or resistance to enhanced due diligence. 

• Frequent account closures and openings to avoid detection. 

• Unexplained complex legal structures (trusts, foundations, offshore accounts). 

Case Example: 

A customer refuses to disclose beneficial ownership details and insists on processing transactions under different corporate entities. This raises serious compliance concerns. 

7. Large Cash Transactions or High-Risk Sectors 

Certain industries are more susceptible to money laundering. MLROs should pay close attention to: 

• Businesses dealing with high volumes of cash (casinos, money service businesses, luxury goods dealers, real estate, etc.). 

• Unusual large cash deposits followed by immediate withdrawals. 

• Transactions that do not align with a company’s declared operations. 

Case Example: 

A jewelry store that primarily deals in high-value items suddenly starts depositing large sums of cash without corresponding inventory purchases. This could indicate money laundering.
