AML & PEP Screening Explained: Sanctions, Watchlists, Adverse Media

AML screening, PEP screening, sanctions screening, and adverse media screening are often bundled together as one thing. They are related but distinct, and a strong programme treats them as separate disciplines with separate tolerances.

Sanctions screening

Hard regulatory requirement. A sanctions hit is binary: you cannot do business with the customer, full stop, in the jurisdiction that imposed the sanction. Screen against OFAC, UN, EU, HMT, OFSI, and any locally relevant list at onboarding and daily thereafter.

PEP screening

Politically exposed persons are not banned but require enhanced due diligence. The hard part is matching: PEP names often appear with multiple spellings and aliases across decades of public records.

Adverse media

The widest net and the noisiest. Done badly, adverse media buries analysts in alerts. Done well, it surfaces customers facing investigations, indictments, or reputational risks the regulator will care about.

Controlling false positives

The best providers tune fuzzy matching per jurisdiction, deduplicate matches across lists, and apply analyst adjudication before an alert reaches your compliance team.
