Enhanced Due Diligence: Triggers & Process
5 min read · KYC Analyst
Know exactly when standard CDD isn't enough. You'll identify EDD triggers including PEPs, correspondent and private banking, and finally nail the interview-favorite distinction between source of funds and source of wealth — with corroboration, not just claims.
EDD: when standard isn't enough
- EDD = a deeper, evidence-backed level of due diligence
- Required on a risk-sensitive basis (FATF Rec. 10)
- Goal: understand the relationship well enough to defend keeping it
Enhanced due diligence, or EDD, is what you do when standard CDD isn't enough to get comfortable. FATF Recommendation 10 requires enhanced measures for higher-risk customers, and the FFIEC manual spells out what that looks like in practice. EDD means going deeper and demanding more evidence: more documentation, more verification, senior sign-off, and ongoing scrutiny.
The goal is to understand the relationship and the customer's money well enough that the institution can defend the decision to bank them. If you can't reach that comfort, EDD is also where you decide the relationship isn't worth the risk. Think of EDD as moving from 'we've met the minimum' to 'we genuinely understand this customer and can stand behind banking them.'
What triggers EDD
- High-risk customer rating from your model
- PEPs and their close associates (FATF Rec. 12)
- Correspondent banking and cross-border relationships
- Private banking and high-net-worth clients
- High-risk geographies, complex structures, adverse media
So what trips EDD? Most directly, a high-risk rating from the model in lecture five. Beyond that, certain categories trigger it almost automatically.
PEPs and their close associates, under FATF Recommendation 12, generally warrant enhanced measures and senior approval. Correspondent banking — where you provide accounts to other banks — is treated as inherently higher risk because you're relying on another institution's KYC; that's why FATF Recommendation 13 and the Wolfsberg CBDDQ exist. Private banking and high-net-worth relationships get EDD because of the size, secrecy, and complexity involved.
And high-risk geographies, opaque ownership structures, and serious adverse media all push a customer into the enhanced lane.
Source of funds vs source of wealth
- Source of funds — origin of the specific money in this transaction/account
- Source of wealth — how the customer built their overall net worth
- EDD usually needs BOTH, with corroboration
- Classic interview question — know the difference cold
Here is the single most important distinction in this lecture, and a near-certain interview question. Source of funds is the origin of the specific money moving through the account right now — this deposit came from the sale of a property, that wire is proceeds of a business contract. Source of wealth is bigger: it's how the customer accumulated their total net worth over time — an inherited estate, decades of business ownership, an IPO.
A wealthy client might have a clean source of funds for one transaction while their overall source of wealth remains unexplained, or vice versa. EDD typically requires you to understand and corroborate both. Know this cold.
Interviewers will often hand you a one-line fact and ask which one it describes, so practice classifying examples until it's instant.
Corroborating the story
- Don't just record claims — verify them
- Funds: contracts, sale deeds, payslips, account statements
- Wealth: company filings, audited accounts, tax records, public profile
- Look for a coherent, consistent narrative
EDD isn't a longer questionnaire — it's a verified one. When a customer says their wealth comes from a family manufacturing business, you don't just write that down; you corroborate it. For source of funds, that might mean a sale contract, a property deed, payslips, or bank statements showing the money's path.
For source of wealth, it might mean company registration and filings, audited financial statements, tax records, or a credible public profile. The analyst's skill is checking whether the pieces form a coherent, consistent story. If a customer claims modest earnings but moves enormous sums, or the documents contradict the narrative, that inconsistency is the finding — and it heads toward escalation.
Correspondent and private banking specifics
- Correspondent: due-diligence questionnaire, no shell banks, no nested-bank surprises
- Wolfsberg CBDDQ standardizes the questions
- Private banking: senior oversight, ownership of EDD, ongoing review
- Never bank an unverifiable counterparty just for revenue
Two special cases deserve a word. In correspondent banking, you're trusting another bank's controls, so EDD focuses on understanding that bank's AML program, confirming it isn't a shell bank with no physical presence, and learning whether it provides nested correspondent services to other institutions you can't see. The Wolfsberg Group's Correspondent Banking Due Diligence Questionnaire standardizes exactly these questions across the industry.
In private banking, the FFIEC manual expects heightened senior oversight, a designated owner of the relationship's due diligence, and frequent review — because the wealth is large, often offshore, and sensitive. In both, the discipline is the same: never let revenue pressure override an unverifiable counterparty. The common thread across both special cases is humility about what you can't see, and a refusal to let commercial pressure paper over a gap in understanding.
Recap
- EDD = deeper, evidence-backed diligence for higher risk (FATF Rec. 10)
- Triggers: high-risk rating, PEPs, correspondent, private banking, geography
- Source of funds (this money) vs source of wealth (overall net worth)
- Next: keeping the whole file current over time
Let's recap. EDD is the deeper, evidence-backed diligence you apply to higher-risk customers under FATF Recommendation 10. It's triggered by a high-risk rating, by PEPs, by correspondent and private banking, and by high-risk geographies or structures.
Its heart is the difference between source of funds — the specific money now — and source of wealth — the whole net worth — both corroborated, not just recorded. You've now onboarded, screened, rated, and deepened the file. But customers change, and a file that's true today can be dangerously wrong next year.
Keeping it current is ongoing monitoring, and it's next. Go test yourself first.

Test your knowledge
A few KYC Analyst questions on this material — pick an answer to see the explanation.
Q1. The Corporate Transparency Act requires companies to report their beneficial ownership information directly to FinCEN under 31 CFR 1010.380. How does this obligation differ from the CDD Rule?
Q2. A customer's ownership chain runs: Natural Person A owns 40% of Trust X, Trust X owns 80% of Operating LLC. What is Person A's indirect ownership stake in Operating LLC, and does it trigger the CDD Rule's ownership prong?
Q3. A bearer share certificate represents ownership of your legal-entity customer. Why are bearer shares treated as a red flag in beneficial ownership analysis?
Q4. What does OFAC's SDN List stand for, and what is the practical effect of a verified true match?
