Enhanced due diligence (EDD) is the deeper set of checks a regulated firm applies to customers or transactions that present higher money laundering risk. It goes beyond standard due diligence to establish where money and wealth come from, who really controls the customer and whether the relationship makes sense. It ends with a senior person deciding whether to proceed.
Why does enhanced due diligence matter once agents act?
EDD cases are where the hard judgements sit. A politically exposed person, a customer in a higher-risk jurisdiction or an unusually complex ownership structure each need someone to weigh evidence that rarely fits neatly. Agents are well suited to the research. They are not suited to the decision, and we hold that enhanced due diligence still needs a person.
The reason is accountability. Most regimes expect senior management to approve higher-risk relationships. That approval is meaningful only if the approver has read the evidence and owns the conclusion. A compliance agent works in the second line, never as the last word.
What does EDD involve in practice?
The exact triggers and measures come from national law and the firm's own policy, but EDD typically adds:
- Evidence of source of funds for the relationship or specific transactions.
- Evidence of source of wealth: how the customer built their overall assets.
- Fuller ownership and control analysis, including people behind nominees and trusts.
- Adverse media and screening across more sources and associated parties.
- Senior management approval to start or continue the relationship.
- Closer ongoing monitoring, with lower thresholds and more frequent review.
An enhanced due diligence checklist turns these into tasks with evidence for each.
An example with a high-risk customer
Take a private bank onboarding a business owner who is a former senior official in a ministry abroad. The agent assembles the file: public declarations of assets, the sale of a family company described in local press, property records and bank statements the customer provided. It notes that the statements are declared evidence and the press report is external, and that a large transfer in the statements does not match the sale price reported.
The analyst asks the customer for the sale contract, verifies it and writes a recommendation. A senior manager reads the file and approves the relationship with tighter monitoring. The guide to running enhanced due diligence on high-risk customers with an AI agent covers each step.
How is EDD different from customer due diligence?
Customer due diligence applies to every customer: identify them, verify them, understand the relationship and keep the file current. It is the baseline.
EDD is triggered by higher risk and asks harder questions. CDD asks who the customer is; EDD asks whether the customer's money and story hold together. CDD can often be completed from standard documents and registries; EDD usually needs explanation, corroboration and a senior sign-off. In agent terms, much CDD work can run at draft depth with routine approval, while EDD work should always end at a named, senior person.
Which terms sit next to EDD?
- Politically exposed person: a common EDD trigger.
- Source of funds and source of wealth: the two evidence questions at the heart of EDD.
- Risk-based approach: the principle that sets when EDD is needed.
Questions people ask
Can EDD be completed without contacting the customer?
Sometimes, from public and internal sources, but often the firm needs documents only the customer has. An agent can draft the request, avoiding any hint of suspicion, and a person approves it before it is sent.
How often is EDD refreshed?
More often than standard reviews, on a cycle set by policy and whenever a trigger occurs. The refresh should test whether the original explanation still fits the customer's current activity.
