5 Red Flags That Should Trigger Enhanced Due Diligence

Standard due diligence is the baseline for every customer relationship, but certain situations call for a deeper level of scrutiny. Enhanced Due Diligence (EDD) is a more thorough investigation applied to higher-risk customers and transactions. The challenge for compliance teams is knowing when to escalate from standard to enhanced procedures. Here are five red flags that should always trigger EDD.

1. Politically Exposed Persons (PEPs)

When a customer or their close associate is identified as a PEP, enhanced due diligence is mandatory under most regulatory frameworks. PEPs hold positions that could be exploited for corruption or money laundering, so they inherently present elevated risk. EDD for PEPs should include senior management approval for the relationship, establishing the source of wealth and source of funds, and enhanced ongoing monitoring.

2. Complex Ownership Structures

When a corporate customer has a multi-layered ownership structure — particularly one involving shell companies, trusts, or nominees — it can be difficult to identify the true beneficial owners. This complexity may be legitimate, but it can also be used to obscure illicit activity. EDD should involve tracing the ownership chain to its ultimate beneficial owners and understanding the business rationale for the structure.

3. High-Risk Jurisdictions

Customers based in or conducting significant business with countries identified as high-risk by FATF, the EU, or your national regulator warrant additional scrutiny. High-risk jurisdictions are those with weak AML controls, high levels of corruption, or that are subject to international sanctions. EDD should include understanding the nature of the customer's business in those jurisdictions and applying stricter transaction monitoring.

4. Unusual Transaction Patterns

Transactions that do not align with a customer's stated business purpose or known profile are a significant red flag. This includes:

  • Sudden spikes in transaction volume or value
  • Frequent transactions just below reporting thresholds
  • Payments to or from unrelated third parties, particularly in high-risk jurisdictions
  • Round-number transactions with no clear business purpose
  • Rapid movement of funds through multiple accounts

Any of these patterns should prompt a review and potential escalation to EDD.

5. Adverse Media Hits

When a customer appears in negative news coverage related to financial crime, fraud, corruption, or other relevant offenses, this is a clear signal for enhanced scrutiny. Adverse media screening should be part of both onboarding and ongoing monitoring. When a hit is identified, compliance teams should assess the credibility and relevance of the reporting and determine whether the relationship should continue.

Responding to Red Flags Effectively

Identifying red flags is only the first step. Your compliance program needs clear procedures for escalating to EDD, including who is authorized to approve high-risk relationships, what additional information to gather, and how to document your decisions. Automation plays a critical role — manual processes are too slow and inconsistent to catch every red flag.
